Chapter 1: After Curfew

Chapter Text

Harry’s foot was caught in the trick stair and the Triwizard egg flew out his hands and tumbled down the stairs, opening up and wailing for the whole corridor and castle to hear.

 

To Harry’s absolute horror Severus Snape turned the corner and picked up the egg. He closed it and the corridor rang with silence.

 

“Potter! I know you're here under that stupid cloak of your father’s!” Snape said as he made his way steadily to the base of the stairs, grasping thin air in front of him.

 

Harry could do nothing but watch as Snape edged his way closer. Eventually Snape started climbing the stairs and it wasn't long before Harry was shrinking against the wall as Snape grasped the invisible fabric right in front of his face.

 

With one tug Snape removed the invisibility cloak and revealed Harry stuck in the staircase and looking horrified and guilty. Severus was overwhelmed with a feeling of glee at catching Potter in such a blatant display of rule breaking. He smirked, though to Harry is appeared as just a snarl.

 

“Thought you'd get away with stealing restricted potions ingredients from my private store, did you Potter?” He spat, inches from Harry’s face. Harry flinched as some spit landed on his cheek. He ignored it, thinking it would probably make Snape more angry to wipe it away.

 

“No professor! I promise I haven't been in your stores! It was Crouch!”

 

“Crouch?” Snape scoffed. “What a ridiculous accusation. You're a thief and a liar, Potter, and it's about time someone taught you how to behave!” 

 

With that, Snape grabbed Harry by the collar and marched him through the castle and into the Potions classroom. Snape looked angrier than Harry had ever seen him.

 

Once inside the classroom Snape shoved Harry into one of the desks. Harry turned around, the tops of his thighs resting on the wooden table. Snape had started pacing up and down.

 

“What are your crimes, Potter?”

 

“Umm,” Harry said. “Er, I was out after curfew.”

 

“And?”

 

“And nothing! I told you I didn't steal anything!”

 

“Liar!” Snape hissed. “If you don't confess to your crimes I promise your punishment will be even worse, you disgusting little shit.”

 

Snape had sworn at him. Harry knew this was bad. If he continued to argue his innocence he knew Snape would make the punishment worse. Probably detention every week for the rest of the year. Or maybe cleaning the whole castle with a toothbrush. Harry gave in and decided that confessing to a crime he didn't commit would be better in the long run.

 

“I … I stole from your private store,” Harry said in a resigned voice.

 

“Well done on finally learning how to tell the truth,” Snape sneered. “So list all your crimes and then we can begin the punishment.”

 

“I was out after curfew…and I stole from your private stores,” Harry said. “Sir,” he added, in an attempt to look contrite.

 

“And?”

 

“And what?”

 

Snape grabbed Harry by the collar and pulled his hair back so his neck was exposed. Harry gasped. Snape leaned in to his ear. “If you don't show me the respect I deserve and call me ‘Sir’ I will make your punishment so much worse you'll be on your knees begging it to stop, you filthy lying arrogant delinquent.”

 

Harry’s head was pulled so far back and the fingers grabbing his hair were pulling so tightly his eyes began pricking with tears from the pain. 

 

“I'm sorry, sir. I didn't mean to disrespect you! I just wasn't sure what my third crime was. I promise I'm sorry, sir!” Harry gasped out.

 

“You're a liar, Potter, or have you forgotten?” Snape said, finally letting go of Harry and taking a step back.

 

Harry took in a few lungfuls of air and desperately tried to stop tears from falling. He certainly wasn't going to cry in front of Snape.

 

“Well?” Snape demanded.

 

“M-my crimes are” Harry began. “My crimes are being out after curfew, stealing from your stores, and then lying about it, sir.”

 

Harry was looking down, trying to avoid seeing that angry face again. Severus waited until he looked up. 

 

“And what do you think those crimes deserve?”

 

Harry paused and Snape felt a fluttering in his chest. This was so far going very well. He was so close to breaking the boy and Snape was getting giddy with the excitement of it. However, he continued to look stern and impassive while Harry was looking at him.

 

“They deserve punishment, sir” Harry said, conceding.

 

“They deserve or you deserve?”

 

Harry bowed his said and said very quietly, “I deserve it.”

 

“Mr Potter you are being willfully facetious and if you carry on you will have to add that to your list of crimes!” Snape was angry again and Harry startled, wanting to de-escalate the situation as much as possible.

 

“I deserve punishment, sir! I deserve to be punished.”

 

Snape took a breath in and let his face soften slightly. Harry appeared somewhat relieved that he wasn't getting increasingly angry.

 

“How were you punished at home as a child, Potter?”

 

“What does that have to do-” Harry stopped midway at the anger returning to Snape’s face. He changed tack immediately. “They spanked me, sir.”

 

“Right well that seems a good place to start for your first transgression.”

 

Harry was confused.

 

“Take off your trousers and pants and bend over the desk, Potter.”

 

Harry didn't move. He was alarmed. He had expected lines or a boring but laborious task. He hadn't expected a spanking .

 

Snape noticed the hesitation and knew he had to head it off before Harry could develop any confidence in the matter.

 

“Mr Potter, if you do not strip and bend over right now I will carry out this punishment tomorrow morning at breakfast on the platform in the Great Hall and the whole school can watch you get spanked like the dirty little boy you are.”

 

Panic rose in Harry’s chest at the thought of such a humiliation happening in public. He quickly pulled his trousers and pants down to his ankles. His face went bright red with embarrassment as Snape looked directly at his penis.

 

“My, my” Snape said, smirking. Harry tried to turn around to bend over but Snape stopped him with a hand on his upper arm. Harry flinched but Snape ignored it. “I thought you were supposed to be the golden boy, the boy who lived, hero of the wizarding world, Potter. I bet you're very happy no one knows what a tiny little penis you have.”

 

Harry’s face went even redder as he burned with shame. He kept his eyes on the wall, purposefully avoiding Snape’s gaze.

 

“No wonder you were so quick to get naked just now when I suggested spanking you in front of the whole school. Then everyone would know what an embarrassingly tiny cock you have. Tell me, do the other boys in your year know about it?”

 

Harry said nothing.

 

“No, I bet you hide it every chance you get. It wouldn't even take your whole hand to hide it - you can probably just use a finger.”

 

Harry tried to cover his cock and balls with his hands but Severus grabbed them to stop him.

 

“No, no, Mr Potter. This seems to be an excellent punishment for you. Stand up proudly with your tiny cock. Although,” he said, moving to face Harry so he could get a better look at his little boy penis, “maybe it's too small to even be called a cock. I haven't seen one this small even on the little first years. I think there are even some girls who have clits bigger than this miniature thing. So maybe this should be called a baby cock. A cocklet. A little tiny baby cocklet.” 

 

Snape was grinning as Harry continued to stare at the wall, consumed with shame. Snape let the silence of humiliation hang in the air for a minute.

 

“Bend over the desk then, Potter.” Snape said, as if he hadn't just spent the last few minutes humiliating the schoolboy.

 

Harry stiffly turned and bent over the desk, resting on his forearms. Snape tutted and pushed his head down so his cheek was flat against the wood. 

 

“Take a step forward.”

 

Harry took a small step forward.

 

“Do I have to threaten you so you do it properly?”

 

Harry took a bigger step forward, his small penis getting slightly crushed against the wood. He felt tears at his eyes again. He had never been so ashamed in his life. He tried to regulate his breathing. 

 

Snape noticed this. “Good boy,” he said, hoping the praise would disarm the lad. He saw Harry stifle a gasp at the words. 

 

Snape walked up to the desk and looked properly at Harry’s backside. The table was slightly lower than his hips so his bum was sticking in the air slightly. It was nice and round - probably from all that quidditch. It looked like it would bounce nicely when smacked. Severus was struggling to contain his excitement. He pressed his hand to the base of his own cock to calm himself down. It wouldn't do to come in his pants.

 

“Open your legs out.”

 

Harry didn't hesitate and he didn't question it. Clearly the earlier humiliation had dampened down whatever spirit the boy had once had.

 

“Wider,” Severus said and the boy spread his feet further until Severus had a good view of his teenage ball sack hanging down, pressed against the table. The boy’s cocklet wasn't visible as it wasn’t long enough to be seen underneath his balls. Severus had to stop himself from reaching out and touching.

 

“You will receive ten spanks for each crime. You committed three crimes so how many spanks will you get?”

 

“Thirty, sir” Harry said quietly, his eyes shut.

 

Without further ado, Severus conjured a wooden paddle and hit Harry across both buttocks with a medium strength. The boy yelped and jolted and Severus enjoyed watching his little bum jiggle.

 

“After every spank you will count the number and say ‘thank you for punishing me Professor Snape’, do you understand, boy?”

 

Harry looked as though he may argue so Severus spanked him again, slightly harder. The boy jolted again.

 

Through gritted teeth he said, “two, thank you for punishing me Professor Snape.”

 

“Oh no, you didn't count the first one and, quite honestly, you don't seem as thankful as you said for that second one. No, I think we’ll start again from scratch. Start at one, Potter.”

 

SMACK

 

“One, thank you for punishing me Professor Snape.”

 

SMACK 

 

“Two, thank you for punishing me Professor Snape.”

 

Severus decided to hit harder.

 

SMACK

 

“Arghh, no, ahh,” the boy said, gasping. “Th-three,” he said, holding back a sob. “Th-thank you for puni- punish- punishing me, Professor Snape.” 

 

Severus palmed his own cock again. The boy was whimpering and it was just perfect . His arse had turned a shade of dark pink and Severus was practically drooling at the thought of it turning a deep bruised red.

 

“Well done, Harry, you’re taking your punishment so well.” 

 

A strangled sob came from the boy. He was so close to breaking, Severus could feel it. The boy needed just a bit more comfort and then he’d be like putty in Severus’s hand. He stepped closer to Harry and gently caressed his burning bum. Harry gasped.

 

“It’s okay, Harry,” Severus soothed. “I know it feels like a lot but you deserve this punishment. You said so yourself. We have 27 more to go and we both know you won't be able to hold back tears for all of those. Look how pathetic you are after just three!”

 

Harry shook with silent sobs.

 

“Just let go Harry. You can cry. No one else can see you.”

 

With that Harry let out a big sob and tears started streaming down his face. Merlin, the crying boy was beautiful. Severus stopped stroking the boy’s bum and picked the paddle up again.

 

“Okay, Harry, we're going to continue now. We're on strike four, do you think you can manage it?”

 

Severus waited as the boy’s crying gradually calmed down. He nodded and Severus lost no time.

 

SMACK

 

“F- four, thank you for p-punishing me Professor Snape.”

 

SMACK

 

SMACK

 

SMACK

 

SMACK

 

Severus continued hitting the boy, making sure to cover his whole arse and upper thighs in welts. Harry continued to cry and sob and stutter but he dutifully counted and thanked Severus after each hit. 

 

When they got to ten Harry’s bum was a bright angry red and Severus could almost feel the heat emanating from it. 

 

“Okay Potter, just twenty strikes left.”

 

Harry jerked at the news and more tears fell. He wasn't sure he could cope with another twenty strikes. 

 

“I'll tell you what Harry,” Snape said, moving back into his more gentle voice (which was still a lot harsher than any other teacher’s voice). “I'll let you have a choice. You can either continue with the twenty strikes to your buttocks, or you can reduce it to ten strikes…but it will be on your balls.”

 

“M-my balls, sir?” Harry said, evidently confused.

 

“Yes, I will slap your balls ten times.”

 

“With the paddle?” Harry was alarmed.

 

“No,” Severus said. “Those slaps would be with my hand and much more gentle.”

 

Harry thought about it. Having his balls slapped sounded horribly painful. But on the other hand he honestly didn't think he could take another twenty hits to his arse. It was burning in agony.

 

Severus waited.

 

“Okay, erm, l’ll take the ten to my balls,” Harry said. “Sir,” he added, quickly, hoping Snape had missed his slip up.

 

Snape hadn't missed it but was too overcome with happiness at getting to spank Harry’s sensitive balls that he didn't care. He schooled his face back into neutral.

 

“Potter, stand up and then lay on your back on the table.”

 

Harry stood up stiffly and moved his legs. Severus cast a quick wordless charm at the desk to make it colder as Harry turned around. Taking a readying breath, Harry sat on the table, hissing as his burning bum made contact with a surprisingly cold table. Severus smirked.

 

Harry moved and lay down on his back, the coldness of the table simultaneously making his bum hurt more but also soothing it. Unsure what to do with his arms, he placed them down at his sides.

 

Severus moved closer and looked at the the little penis sitting on a bed of sparse dark pubic hair, with Harry’s balls acting as a cushion. His penis was probably about two inches long and Severus longed to touch it. 

 

“I will cup your balls in one hand and administer the strike with the other. You will count and thank me as before. Do you understand, Potter?”

 

“Yes, sir,” Harry said nervously. 

 

Severus touched Harry’s balls with both hands, caressing the soft skin there and massaging them. Harry gasped and Severus noticed the boy’s little cocklet begin to twitch. He tried to suppress another smirk.

 

“You I'll have to hold your baby cock out the way, Potter.”

 

Harry moved to grab his penis, unsure what to do with it, and horrified that his touch had caused him to get the beginnings of a semi.

 

“Here,” Severus said, slapping Harry’s left arm away and moving his penis so it rested against his lower abdomen. Severus enjoyed the brief contact with the little cocklet but knew he couldn't linger. He grabbed the boy’s right hand and covered his cock with it. He now had an unobstructed view of the boy’s balls and he returned to cupping and massaging them, watching Harry’s mouth gasp in a little ‘o’ as his right hand was clearly jolted by his filing cock.

 

“Are you ready Mr Potter?”

 

“Yes, sir,” Harry said anxiously.

 

SLAP

 

Harry’s whole body jerked as Severus hit both his testicles with the palm of his hand. Harry’s eyes were watering and his hands had moved to steady himself on the table, letting his cock flop back down. Severus noticed it was now completely flaccid.

 

“Oh, fuck!” Harry whimpered. 

 

“Potter-” Snape began sternly.

 

“One- please, I meant- I meant one, thank you for punishing me Professor Snape!”

 

Harry was clearly in pain and Snape loved it. He suppressed a grin and decided to let it slide. He still had nine more slaps after all. He lifted Harry’s balls and aimed for the underside.

 

SLAP

 

Harry jerked again, not having been ready for the hit. 

 

“Two,” he gasped. “Thank you for punishing me, Professor Snape.”

 

“If you're that thankful you should be holding your pathetic baby cock out the way,” Snape snarled. “Or would you prefer I hit your cocklet instead?”

 

“No! No, please, sir. Please don't hit it!”

 

“Don't hit what?” Snape asked innocently.

 

“My cocklet - my baby cock,” Harry said, oblivious to the words he was saying as he grasped his penis and moved it out the way again. “Please sir, don't hit my baby cocklet.”

 

“Very well, we shall continue.”

 

SLAP

 

SLAP

 

SLAP

 

SLAP

 

SLAP

 

On and on it went, Harry jerking to each hit, unable to control his instinctive reaction to the pain of being repeatedly hit in his testicles. He was crying again, sobbing loudly but Snape didn't seem to care. His balls throbbed and ached and he wasn't sure they would ever be pain-free again. His arse still burned but his balls were so much worse. He regretted not having gone for the twenty hits. He couldn't cope with this much agony. He lost track of where he was and why this was happening. All he could think about was the searing pain in his balls.

 

Eventually it seemed to be over and Snape was soothingly whispering “it’s okay, you're okay” to him as he gently massages Harry’s balls.

 

Harry kept crying and sobbing, no longer sure how to stop. Snape muttered a spell and a jar flew to his outstretched hand. He opened it and started applying some ointment to Harry’s sore balls, continuing to offer words of comfort. 

 

Harry gradually felt himself calming down. He just lay there, staring at the ceiling, allowing Snape to massage his throbbing balls.

 

Harry didn't even react when Snape started applying ointment to his little baby cock. He was moving ointment around the shaft and twirling it over the head. When he sipped a finger into Harry’s slit Harry jerked and became aware of what was going on. He was hard. He was hard and his potions professor was wanking him off, using ointment as lube. Harry whimpered again.

 

“You took your punishment so well, Harry,” Snape said. “Would you like a reward?”

 

Harry didn't say anything. He couldn't. His teacher was wanking him off and he was doing nothing to stop it. Renewed feelings of shame washed over him. He nodded.

 

“Say it, Harry.”

 

Harry remained silent and impassive.

 

“Say you want me to make you come. Admit that you're a dirty little boy-whore and you want your potions master to play with your baby cocklet because you want to come. Say it Harry.”

 

Harry whimpered again, more tears rolling down his face.

 

“Please, sir,” he whispered.

 

“Please what, Harry?”

 

“Please make me come.”

 

Severus kept up the same slow pace, knowing it wasn’t enough to bring Harry over the edge.

 

“Please wank me off. P-please play with my tiny baby cocklet and let me come.”

 

“Why, Harry?” Snape pushed the crying boy.

 

“Because I'm a dirty boy-whore and I want to come! I want you to make my tiny cocklet come!” Harry practically shouted it.

 

Severus grinned and sped up his movements, watching Harry’s face as he gasped with need and want while still covered in his own drying tears.

 

One more pull and Harry was coming. Small white spurts erupted from his cocklet and drizzled over Severus’s hand. He wanked the boy through his orgasm and still held onto his flaccid cock as Harry went boneless on the table, his eyes shut.

 

Severus moved his hand in front of Harry’s face and used his other hand to grab the boy’s hair again.

 

“Are you going to clean your filthy mess up, Potter?” He snarled harshly.

 

Harry opened his eyes in surprise and saw the come-stained hand in front of his face. Broken and pliant, he simply sighed and said, “yes, sir”. 

 

Severus moved his hand to the boy's mouth and he obediently stuck his tongue out, licking his own come of Severus’s fingers. Severus watched, stunned, as the boy did exactly what he wanted with no backtalk or hesitation. 

 

Once his hand was clean Severus took a few steps back. Harry slowly began to sit up on the desk, his t-shirt, which had remained on, covered in sweat and his trousers and pants still down at his ankles. 

 

“Is that all, sir?” Harry said.

 

Severus nodded and Harry stood up and re-dressed himself. He noticed his invisibility cloak was missing. Presumably Snape had it, but he didn't want to ask for it back and risk another punishment. His arse and balls were still throbbing, especially now they were being constantly touched by his underwear. He grimaced knowing the trip back to Gryffindor tower would be very uncomfortable.

 

As Harry made his way to the door, Severus spoke up, making Harry pause.

 

“You did well today Mr Potter. Let us hope your behaviour from now on starts to improve or else we may need to have a repeat of tonight’s punishment and I promise you next time I won't be so kind.”

 

Harry stood dumbfounded. Severus thought that he had been kind tonight? Harry nodded and quickly left the classroom, keen to put as much space between himself and the potions master as he could.

 

If there was one thing Harry knew it was that he had absolutely no intention of ever finding out what Severus Snape’s idea of an unkind punishment might be.

Chapter Text

The Second Task of the Triwizard Tournament had been and gone and no one, including Severus himself, would have guessed that Harry Potter participated with a reddened and bruised backside. It had been two weeks since the task (and Harry’s punishment) and Harry had behaved impeccably for the whole duration, much to Serverus’ annoyance.

 

Severus had been looking closely for any minor infraction that he could use to punish the boy again. During most of his classes he thought endlessly about new ways to punish the arrogant brat and longed for him to make just one slip up.

 

It was the final class of the day - fourth year double potions - and Severus had been watching Harry closely. The boy hadn't passed any notes, had ignored Weasley when he tried to engage him in a whispered conversation, and had even made a passable attempt at the potion they were working on. 

 

But part way through the class Severus noticed Harry fidgeting. Over the next ten minutes Harry glanced at the clock seven times, changed position four times, and seemed irritable with his friends. Severus glided silently to the back of the room where he could better overhear their teenage conversation.

 

“I don't know why you're being so weird about this, Harry,” Weasley was saying. “Just ask Snape if you can use the bathroom. Even he isn't mean enough to refuse you a piss when you need it.”

 

“No, Ron,” Harry said, slightly strained. “I don't want to give him any excuse to punish me. I can hold it, it's fine.”

 

Weasley scoffed and shrugged, turning back to his own potion.

 

Over the next half an hour Severus watched as Harry started getting more fidgety. He would frequently sit down to cross his legs and then stand up a few seconds later and hop on one foot then the other. Severus was sure he could see his forehead glistening with sweat from the effort of his task.

 

Severus walked up to the Gryffindor table and inspected the potions, his nose raised in distaste. When he arrived at Harry’s cauldron he made a snarky comment about too much water having been simmered off, which was a complete lie. He then followed it by ‘demonstrating’ to the Gryffindors how to correctly rehydrate a potion. Sticking his wand out he cast an aguamenti and allowed a slow but steady stream of water to pour from the tip of his wand and into Harry’s cauldron, directly in front of Harry’s face.

 

The boy looked to be in pain while watching the water stream. Severus smirked and turned to leave.

 

“Ah, professor?” Harry asked in a low whisper. 

 

Severus turned. There was still fifteen minutes to go until the end of class. He raised an eyebrow.

 

“Please sir, could I be excused to use the bathroom?” Harry’s eyes were wide and staring directly into Severus's, imploring him to agree.

 

Severus smirked again and said, with no attempt to keep his voice quiet, “Mr Potter I was under the impression you were a young adult and not a child.”

 

Harry turned bright red and looked down.

 

“Either you are a young adult who can control his bladder and therefore can wait until the end of class, or you are a child who should be wearing nappies until you are toilet trained. Which are you, Mr Potter?”

 

The Slytherins were doubled over with laughter at this point and the whole class was staring at Harry, who tried to shrink down as small as possible. He muttered something inaudible.

 

“What was that, Potter? Are you an adult or should I find you a nappy?”

 

“I'm an adult, sir.”

 

“Very well, then,” Severus said, turning and walking away.

 

The next fifteen minutes were agony for Harry. He was so close to wetting himself he couldn't do any of his work. He sat on his stool and gripped the edges so tightly his knuckles turned white. He was so tense he even told Ron to fuck off when he tried to offer sympathy.

 

The fifteen minutes passed torturously slowly but eventually Snape dismissed them. Harry already had his stuff packed away, ready to sprint to the closest bathroom. He stood up and had only taken three strides when Snape called out.

 

“Mr Potter, please stay behind.”

 

Harry couldn't believe it. He turned and stared at Snape with incredulity. Snape continued to look completely unphased, even slightly disinterested.

 

Harry’s fellow students gradually left the classroom, sniggering at him as they passed. Harry glared at all of them.

 

When they were finally alone Severus threw up wordless locking and silencing spells, which Harry didn't notice because he was too focused on not wetting himself. 

 

Severus stood at the front of class with his arms folded and schooled his face to look severe.

 

“Potter, you have behaved abysmally in class today.”

 

Harry looked ready to interrupt so Snape held up a finger to stop him.

 

“What you have brewed is not even the level of a first year. You have been endlessly restless and you have distracted your fellow classmates. Behaviour like this is not tolerated in my class.”

 

“Of course I've been restless, I've been desperate for the loo!” Harry shouted, now at the end of his tether. 

 

“Not this ridiculousness again!” Snape said, pretending he had forgotten. “You are fourteen years old and should be able to control your bladder by now, you foolish boy!”

 

Harry trembled with rage. 

 

“I can't help needing the toilet! It doesn't mean I'm a child!”

 

Snape’s face twisted in anger and he stepped forward into the boy’s space until he was towering over Harry from above.

 

“You are an insolent, arrogant boy just like your father,” Snape snarled quietly. “Just because others indulge your childishness does not mean I will. You will learn how to behave and how to control yourself like an adult.”

 

Harry’s heart dropped to his stomach. He'd gone too far. Fuck, he thought. He had been doing so well behaving for Snape. And now he'd fucked it.

 

Harry broke eye contact and looked down, trying to become small again. 

 

“Please, sir,” he murmured.

 

Snape scoffed. “Oh, so now you attempt to show me respect? After you've stood in my classroom and shouted at me like a petulant child?”

 

“I'm sorry, sir.” He was still using the same small voice.

 

Snape eyed the boy, who eventually rose his head to meet his gaze. Snape took a few steps back.

 

“You need to learn to control yourself, Potter. I think a time out will teach be valuable to your education. You will simultaneously learn to hold your bladder and your anger.”

 

Harry’s eyes widened in horror. 

 

“Y-you mean now, sir?”

 

“Yes, there is no time like the present to learn something new. Especially as you spent the last hour learning absolutely nothing.”

 

Harry looked too shocked to be angry. He had been standing with his legs tightly crossed and now seemed to be jerking involuntarily at the hips.

 

“Stand there,” Snape said, pointing to space two metres in front of his desk. “You will stand still. You will not move. You will think about your behaviour and where you went wrong. I will be marking homework and if you can exercise patience then I may let you leave before dinnertime is over.”

 

With that, Snape swept behind his desk and took a seat, pulling a pile of parchment towards him.

 

Harry stood dumbfounded. He couldn't possibly stay here for any length of time without wetting himself. But Snape had immediately started marking homework, seemingly disinterested in Harry, and Harry knew if he caused a fuss he would probably be spanked again. And Harry did not want to be spanked again.

 

He sighed and stood in front of Snape’s desk, trying to regulate his breathing and not think about the searing pressure in his pelvis.

 

Barely five minutes later, Snape’s quill scratching in the background, and Harry knew he wouldn't be able to hold it. He was sweating and pretty sure he was making deep groaning sounds of pain. It was just a trickle - one second where urine left the head of his penis before he was able to clamp his pelvic muscles down on the sphincter again.

 

Harry knew this was the beginning of the end, but he also knew he couldn't just give up. A second trickle exited. And then a third, which was really more of a spurt. And then suddenly his penis was expelling urine as though it was the Fountain of Youth. It came and came and Harry felt his pants and his trousers soak through with urine. Felt the warm liquid pour down his legs and into his socks and shoes. And it was still relentlessly streaming from his body.

 

Snape hadn't marked a single parchment and had instead been surreptitiously watching Harry the whole time. His mouth twisted in delight when he saw the boy jerking, and it grew even wider when he saw a faint wet patch appear over the boy’s crotch.

 

He lifted his head and openly stared at Harry as the wet patch grew larger and larger and eventually urine pooled on the floor at the boy’s feet. Harry’s face was a mixture of guilt, fear, and relief. Severus wasn’t sure he'd been this happy in years.

 

When the flow of urine seemed to have stemmed, Snape schooled his face into rage and stood up quickly, making sure to scrape the chair loudly over the stone floor. 

 

Harry looked up, scared.

 

Snape strode forward and grabbed the boy harshly by his hair. 

 

“You filthy, disgusting, depraved child!” he snarled. “How dare you dirty my classroom with your filth!”

 

Harry’s head was pulled back and tears were pricking his eyes from the pain and humiliation.

 

“I'm sorry, sir!” he gasped. “I'm sorry, I'm sorry!” he repeated over and over.

 

“You really are a child. Just a nasty little boy with his little baby cocklet. Unable to control his bladder like a toddler. Is that what you are, Potter?”

 

Harry was being forced to look into Snape’s eyes. He knew a losing battle from his previous punishment with Snape.

 

“Yes, sir.”

 

“What are you, boy?”

 

“I'm a filthy child who can't control my bladder.” His voice was once again small.

 

“And what do filthy boys who make a foul mess need to be?”

 

Harry closed his eyes.

 

“Punished, sir. They need to be punished.”

 

Snape let go of Harry’s hair and took a step back. He moved back to his desk and resumed his seat.

 

“Strip.”

 

Harry hesitated. “Er…what, sir?”

 

“Strip,” Snape said again. “Or would you prefer to remain in those wet and putrid clothes?”

 

Harry sighed and began undoing his trousers while kicking off his shoes. He peeled off the wet trousers and placed them on the floor next to the puddle of his urine. Then he took off his pants, placing them on top, before finally removing his squelching socks.

 

Snape made a motion with his hand which Harry understood to indicate his shirt, which he unbuttoned and slid out of. Snape openly stared at the teenage boy. He was shivering slightly from the coldness of the urine drying on his skin (they were in a dungeon after all). His small penis was lying flaccid. Snape had forgotten how small it actually was. He suppressed a smile.

 

“You will be spanked,” Severus said, ignoring Harry’s intake of breath at the news. “How many strikes do you think you deserve?”

 

Harry looked at him as though this was a trick question, which of course it was. 

 

“Er,” he said, clearly deciding between aiming hopefully low or contritely high. He decided on the former. “Er, it was one crime, so ten strikes?” 

 

“You think using my classroom as your personal toilet is equal to your crimes from the other night? You think soiling your learning environment with your urine is worth only ten measly strikes?” 

 

Harry looked suitably chagrined. 

 

“No, sir.”

 

“Then how many strikes, Potter?”

 

Harry hesitated. “Er, thirty, sir?’

 

Snape smiled. “Yes, I think thirty would be sufficient.”

 

Harry looked horrified. He had been overestimating. 

 

“Sir- I can't- not the paddle- I can't,” he babbled.

 

“Be quiet you silly child. I will not use the paddle tonight. You have behaved like a child so you will be treated like a child.”

 

Harry stayed silent and for a brief while the teacher and student stared at each other over the desk. Then Snape sat back in his chair and opened his legs slightly, which may have made Harry take notice of the bulge of his professor's cock. Harry looked back up at Snape face as Snape smiled.

 

“Come here, Potter. You will lie down over my lap and be spanked like a child.”

 

Harry grimaced. There was no use fighting it, so he sighed and made his way around his professor’s desk and stood in front of Snape, who he noticed was staring at his small penis. Harry closed his eyes and when he opened them again it was to Snape quirking and eyebrow in challenge. 

 

Not wanting to earn further punishment Harry steadied himself and lowered himself over his teacher’s lap. His chest was over Snape’s left thigh and his upper thighs were over Snape’s right thigh. His bum was slightly in the air and he needed to stand on tiptoes to maintain his balance. He was acutely aware that his cock and balls, which had fallen easily between Snape’s parted legs, were now being slightly crushed as Snape moved his legs closer together again.

 

“You will count each strike and thank me, just like last time. Do you understand, Potter?”

 

“Yes, sir.’

 

“Very well-”

 

SLAP

 

It happened before Snape had even finished his sentence. His bare hand had come down and spanked Harry’s right bum cheek.

 

Harry jerked but tried to make no sound. He had hoped that Snape’s hand would be easier than the paddle but he was so consumed with his current pain he didn't have the brain capacity to compare it to the paddle.

 

“One, thank you for punishing me, Professor Snape.”

 

Snape smiled and brought his hand down again, this time to the left bum cheek. 

 

SLAP

 

“Two, thank you for punishing me, Professor Snape.”

 

SLAP

Snape rained down hits on the child's arse. He covered the whole bubble butt, ensuring there was no space on the buttocks that remained milky white. He even included the upper thighs. 

 

After fifteen spanks the boy was sobbing in pain, but he continued to dutifully count the spanks and thank Severus. He longed to see the tears streaking the boy’s face. It really was the worst part about the over-the-knee position.

Severus continued to spank the boy, watching as his arse turned from pink to red to a deep, dark red with areas of purple bruising appearing. It was perfect. It was delicious. Snape wanted to bite into one of the arsecheeks and leave teeth marks.

 

He began stroking the boy’s bum between strikes, having slowed them down to get the most out of the boy’s fearful anticipation of each hit. He gently caressed each cheek and offered soothing words of “almost there” and “you're doing so well”, alongside whispers of “dirty, filthy boy” and “don't forget you deserve to be treated this way”.

 

Harry was sobbing so much it would sometimes catch in his throat and he would have a mild coughing fit. But he kept counting and didn't protest or beg once.

 

As Severus caressed his youthful backside his allowed his fingers to slip into the boy's crack. Each stroke he went slightly deeper until his fingers were brushing the boy’s virgin arsehole. When the boy gasped he moved his hand further down and started massaging the boy’s balls. He could feel the boy’s tiny penis twitch between his legs, although Harry remained quiet and allowed the silent assault.

 

SLAP

Three in quick succession, over the darkest areas of bruising. Harry screamed and forgot to count. He was in agony. His bum was burning and throbbing. It was so raw, it felt like the top layer of skin was missing. And Snape’s touches were soft but each caress sent a jolt of pain through Harry from oversensitivity.

 

Harry could feel his teacher’s fingers between his bum cheeks. He could feel as fingers brushed over his arsehole. He wasn't sure what to do. It didn't feel bad like the spanking. In fact he began to hope Snape would continue to pay attention to his hole and forget about the remaining spanks. 

 

It wasn't to be, however, and soon he was being spanked again.

 

“Th-thirty! Th-th-thank you for p-punishing me, p-professor Snape!” Harry stuttered and gasped, not recognising he had reached the end of the punishment.

 

He lay there floppy, allowing Snape to bear his whole weight - not that it was much. He could feel Snape stroking his arsehole and he allowed himself to give in to it.

 

“Okay, Potter, we should move onto the next stage of your punishment.”

 

Harry stiffened and Snape felt the tiny pucker under his finger contract to become impossibly smaller. He forced himself to not give in to the temptation to shove his finger right into the boy’s tight hole.

 

“The next stage? There's…more?” Harry said, his heart hammering away.

 

“Of course,” Snape drawled as though it bored him. “Now you've been punished you need to actually learn how to control yourself.”

 

“How am I going to do that, sir?” 

 

“Well, first your baby cocklet needs to be hard.”

 

Harry was scared and confused. He didn't know what was happening but he was too afraid to ask.

 

Severus widened his legs again so Harry’s penis hung freely down towards the ground. Keeping his right hand encircling Harry’s anus, he reached his left arm over and around the boy’s waist and grabbed the cocklet as if he were milking an udder. The boy was small for his age so it was surprisingly easy to reach around him.

 

Severus cast a wandless, wordless lubrication spell and began stroking the boy’s baby cocklet up and down, making sure to put his little finger into the boy's slit every other pump. Meanwhile he also continued to circle and press on the boy’s arsehole, gradually adding more pressure though he avoided penetrating the child.

 

It didn't take long for Harry’s teenage cocklet to grow fully hard. Harry was gasping and groaning and Severus stopped his ministrations when the boy tried to thrust his hips into Severus’s thigh. The boy made a sound of disappointment which thrilled Severus greatly. 

 

“Stand up, Potter.”

 

Harry took a while to find his feet, the dual sensations of burning pain in his bum and rock hard erection made it difficult get his balance.

 

“Hands behind your back.”

 

Harry moved his hand behind his back. Snape then cast a spell which moved Harry’s hands further up his back so his hands were grasping the opposing elbow. The spell kept them there invisibly bound.

 

Severus conjured a small metal rod, which was about six inches in length and ribbed down the shaft in a small wave-like pattern. At one end was a flat, circular piece of metal, almost like the base of a candle wick.

 

Harry was desperate to ask what was going to happen but he was preoccupied by Snape’s continued movements over his cock, keeping it painfully hard and swollen.

 

“Right, Potter. What lesson do you need to learn?”

 

“Er,” Harry struggled to think of anything except the pleasure building up in his baby cocklet. “Er, I need to learn how to control my bladder.”

 

“Exactly. In order to do that we are going to have to train you to hold your urine like an adult.”

 

Harry nodded.

 

“You will now hold your bladder until tomorrow morning.”

 

Harry briefly snapped out of the building pleasure.

 

“But, what if I can't hold it, sir?”

 

“Oh, that won't be a problem. You won't physically be able to pass urine until tomorrow.’

 

Harry was alarmed and tried to jerk away but Severus yanked painfully on his cocklet to keep him in place.

 

“What- how- what do-” Harry spluttered.

 

“I am going to prevent you from passing urine until tomorrow morning,” Severus replied calmly. Anticipating Harry’s question, he continued, “If you absolutely cannot control yourself again then you may find me in my quarters and ask for permission to use the lavatory.”

 

Harry was dubious, but his potions master was currently holding his penis and even though he was stroking it harsher than Harry would like, Harry was actively aware that he wasn't in a position to refuse his teacher anything.

 

“Okay, then, sir.”

 

Severus gave a short laugh. 

 

“Potter, this is happening with or without your consent. Though I'm glad I don't have to restrain you further.”

 

With that, he let go of Harry’s penis and let it bounce, jutting out in front of him. He picked up the metal rod and cast the lubricating charm again, coating the cold metal.

 

“Sir, what are you doing with that?” Harry asked, though realisation was dawning on his face.

 

“I am going to insert this into your baby cocklet.”

 

“No!” Harry struggled again the binds to his arms 

 

“Yes, Potter. This is happening whether you like it or not. I am going to plug up your little baby cocklet because you can't be trusted with it, because you’re a dirty and disgusting child who urinates in his trousers.”

 

Harry looked horrified but didn't say anything.

 

“It is either this or wearing a nappy and, so help me, I will force you to wear a nappy and I will show everyone in class tomorrow how much of a toddler you are. Maybe I'll make you hop up on the desk and have your nappy changed in front of the class like the pathetic little baby you are!”

 

Snape was inches from Harry's face and snarling. Harry tried to take some deep breaths. He could do this. He slowly nodded.

 

Severus immediately grabbed his cock and pushed the metal rod into his slit. Harry jerked and tears started falling down his beautiful face, but he bore the pain in silence.

 

Severus slowly moved the rod in further until the tip reached a barrier. He then cast a spell to shrink the sound down so it was the full length of Harry’s urethra. 

 

Just when Harry thought it was over, Snape started to gradually pull the rod out. Each centimetre caused pain as the ribbed waves put pressure on the walls of his urethra. It felt like someone was stabbing him from the inside, ripping apart his small penis. Harry’s sobs got louder.

 

Severus continued pushing the sound in and out of Harry's urethra for a few minutes. He gradually sped up until he was fucking the boy’s penis hole. Harry was almost doubled over in pain. It was delicious. 

 

Severus soon realised the boy wasn't going to cope with anymore, so he fully inserted the sound and cast a spell to keep it in place. The spell would only release on Severus’s command, a fact which he informed Harry with a smirk as he released the invisible binds.

 

“That's all, Potter. Hurry along to dinner or there won't be any left.”

 

Snape turned and Harry gawped.

 

“But, sir-”

 

“Yes?” Snape said, rolling his eyes.

 

“My baby cocklet is still hard, sir, I can't go to dinner like this.” 

 

“What would you like, Potter? Would you like to orgasm like last time? You wouldn't even be able to come with the sound in place. You selfish child.”

 

“What? No! I just-”

 

“But I suppose I can help you reduce your erection so it is less prominent.”

 

Harry sighed, relieved, hoping Snape knew a spell to make it wilt. 

 

But Snape want nearly so generous. He instead grabbed the boy’s penis again with one hand, and in the other he conjured some ice cubes. Without waiting for the boy to react, he ran the ice cubes up and down Harry's cocklet.

 

Harry screamed in pain as his throbbing penis was suddenly assaulted with frozen ice cubes. His whole penis was burning with a stinging pain as the blood rapidly drained away. He stood with his shoulders hunched, knowing he had to endure anything Snape forced on him. He shook with sobs and renewed tears, so overwhelmed with pain. His throbbing arse, his ripped penis hole, and the stabbing stings of freezing cold. It was too much for him to cope with. 

 

Once the ice had melted Severus stepped away and took in the broken boy in front of him. His arse was still a deep red with large bruises covering most of the surface. His cock was once again tiny, though it remained an angry red. He could see the metal plate sticking to the head of the boy’s penis, held tightly by magic. 

 

“Get dressed, Potter. I shall expect to see you here tomorrow morning before breakfast.’

 

Harry nodded and walked dejectedly to his clothes, which were still soaked in urine. He didn't even make a fuss and he re-dressed in the smelling, wet uniform.

 

Severus knew now was the time to wrongfoot the boy by showing him kindness so he quickly summoned a jar of healing ointment.

 

“Potter, wait.’

 

Harry paused, just before the door, too scared to turn around and find another punishment waiting.

 

Severus cast a charm and Harry felt his clothes dry immediately. They still stank of urine, but at least he was dry. 

 

Severus then crossed the small space quickly and handed the jar out to Harry.

 

“Apply once a day until the bruising has gone.”

 

Harry stared in disbelief. Snape clicked his tongue with impatience so Harry lunged for the ointment, remembering to mutter a hasty “thank you, sir” as he left the classroom.

 

Harry walked slowly down the corridor, each step agony as his underwear scraped his bruised bum and the rod shifted inside his small cocklet. Harry knew he couldn't go to dinner like this, or even see Ron or Hermione. So he made his way to Gryffindor tower in the hope that he could collapse on his bed in an empty dormitory and tend to his sore arse.

Chapter Text

Harry spent the evening hiding behind the curtains of his four poster bed. He was so focused on the metal rod stuck in his penis that he couldn't even think of homework or talking to his friends.

He had used the ointment on his sore backside immediately and was grateful that Snape had given it to him. Perhaps he wasn't so bad after all, Harry would think before remembering that he had fucked Harry’s urethra with a metal pole. Eventually Harry drifted off to sleep, the stress of his punishment making him suitably exhausted.

The next morning Harry woke up needing to pass urine. He was instantly reminded of the sound preventing him and cursed Snape again. He couldn't risk his dormmates seeing the sound so he waited until the bathroom was empty and then grabbed a quick shower.

While in the shower he examined the sound and tugged with all his strength but the thing wouldn't be removed. Unfortunately, he found his tiny penis hardening under his ministrations and had to turn the water cold, knowing he wouldn't be able to come with the rod in place.

Making his excuses to his friends, he ran to the dungeon and knocked tentatively on the door to the potions classroom.

“Enter.”

Harry pushed open the door and walked into the room. Snape was sitting at his desk pouring over a parchment and seemingly disinterested in Harry’s presence.

Harry stood in front of his desk and stayed silent until Snape looked up.

“Yes, Mr Potter?” Snape asked with a raised eyebrow, as if he had no idea why Harry was standing before him.

“Um, sir,” Harry began. “I, er, need to use the toilet.”

He flushed red as it said it, embarrassed by his need to pass urine.

“I see,” Snape said slowly, making no move to assist the boy.

“Strip,” Snape said, as easily as if he were asking Harry to pass the salt.

Harry only hesitated for a second before slowly removing his shirt, shoes and socks. He then undid his trousers and slid them down, folded them up and placed them on the floor. The coldness of the dungeon first thing in the morning made his nipples harden, a fact that Severus noticed immediately. He forced himself to stay still and not pinch and pull those delicate nibs.

Harry then hooked his thumbs under his pants and stepped out of them.

“Turn around,” Snape commanded. “Slowly.”

Harry, completely naked now, slowly turned so his back was facing the desk. Severus noticed that his arse was still pink but the bruising had mostly healed.

He made Harry face him and his stomach fluttered in delight at seeing the miniscule cock stuffed full with a sound.

Seemingly unconsciously, Harry began tugging on his penis, likely due to the discomfort. Severus’s anger flared.

“Do not dare to touch your baby cocklet!” he snarled. Harry jumped back and immediately withdrew his hand.

“You are a child and you have to earn the privilege to touch yourself. Your cocklet is stoppered so there is no need for you to touch it at all. You've had that right taken away.”

Harry nodded, still desperate to pass urine.

“Yes, sir,” he said, looking down at the floor.

“Well?” Severus said.

Harry looked confused.

Severus sighed. “Are you going to ask for permission to urinate?”

Harry startled. “Oh, yeah. Please, sir, can I pass urine now?”

Severus looked back at his parchment, purposefully ignoring Harry.

“It doesn’t sound like you're desperate enough yet. Perhaps you should wait.”

“No, sir! Please, no! I promise that I'm desperate! I really need to pee, sir. Please please let me go. I promise I'll behave. I promise to be good!”

Harry looked scared that he might be denied this and he kept staring at Severus, hoping he would give in and be kind. Severus eventually looked up at those innocent green eyes.

“Very well,” he said, as if this were a major inconvenience to him and not something he'd spent the whole night fantasising about.

He stood up and walked over to Harry.

“Hands behind your back.”

Harry dutifully did so, and Severus cast the same invisible binding charm as before to prevent Harry moving them. Severus then moved until he was standing behind Harry, the boys bare bum cheeks pressed up against Severus’s upper thighs. Severus could feel his cock harden and poke Harry is the lower back. Harry said nothing so Severus pushed in further. He then conjured a metal bucket in front of Harry, similar to the kind a maid would use to milk a cow.

“Sir, I thought you were going to let me use the toilet?”

Severus laughed darkly.

“No, Mr Potter, I said I would let you pass urine. You do not need a toilet for that. You are not toilet trained yet, or have you forgotten?”

Harry’s face went bright red and he was ashamed he had to be treated like a child.

“I will remove the sound,” Snape began and Harry paid attention. “In order to do this your baby cocklet needs to be hard.”

Without letting Harry adjust to the knowledge he grabbed the tiny penis and began to wank it off harshly in one hand while massaging the boy’s balls in the other. A cock didn't need to be hard for a sound to come out (it didn't even need to be hard for a sound to go in, just easier) but Severus wanted to teach Harry to associate pain or anything to do with his urethra with pleasure.

Severus could feel the sparse teenage pubes in his hand as he massaged Harry’s testicles. They would have to go, he thought. He liked his boys hairless and girlish. He wondered how long he would have to ‘toilet train’ Harry for before he would rip those pubes out with hot wax while the boy writhed under him.

It didn't take long for Harry to get hard and Severus kept pumping him up and down and up and down with a varying rhythm and intensity. Harry couldn't help a few low groans escaping as his professor masturbated his tiny penis for him. He also couldn't help leaning into the sturdiness behind him. He could feel Snape’s erection press into his back and, for some reason he couldn't understand, it made his baby cocklet twitch.

Severus sensed Harry was near orgasm so he immediately stopped fondling him. Instead he held the penis with one hand, cast the wandless unsticking spell and in one smooth motion removed the sound from Harry’s cocklet.

Harry yelped as he was suddenly brought back from the edge of orgasm with a now-familiar pain burning his urethra. A small droplet of blood appeared at the tip of his penis, which Severus smeared around the head, not wanting to alarm the boy.

“Hold your bladder,” Severus commanded.

Harry stopped himself just in time. He was so tense, overwhelmed with his near orgasm, the pain, his wilting erection, and his full bladder. He strained as he desperately tried not to urinate.

Severus was still holding the boy’s rapidly deflating cock. He held it in his palm as if it were his own penis he was about to use.

He aimed the cocklet at the bucket and said in a low soft voice, “Now Harry, you can pass urine now.”

The boy twitched and his cocklet started leaking urine, gathering speed quickly. Severus ensured it went into the bucket, relishing in the tinkering sound of water splashing against the metal.

The stream seemed endless and Severus couldn't resist moving his index finger into the stream. His own cock twitched as he felt the boy’s warm stream of piss against his finger and felt it drip down his hand. He pressed himself closer into the heat of the teenager in front of him, wishing not for the first time that he was naked too.

Eventually the flow of urine stopped and Severus shook the boy’s penis to release the last drops of water.

Without missing a beat he once again resumed wanking the boy off, using his own urine as lube.

Harry gasped and shuddered, too happy to be once again edging to the orgasm he was denied earlier to protest.

Snape fondled Harry’s balls again, this time using them rougher, pulling and tugging and squeezing. Harry winced. Again. And again. Severus ignored it and continued. He wanted the boy to get used to finding pleasure despite pain. He hoped that, if he played his cards right, the boy might eventually find pleasure from the pain Severus inflicted.

Up and down, up and down, squeeze, pull, tug, harder squeeze. Severus was now almost completely holding Harry up as Harry leant his full slight weight into him. The boy was jerking and twitching in his arms and soon came in a splash of white come, ropes landing on Severus’s hand.

SLAP

Severus slapped the baby cocklet.

Harry jumped, startled, confused, and riding his post-orgasm high, which was now mostly pain in his throbbing cocklet.

SLAP

SLAP

SLAP

Three hits directly on his penis in quick succession. The boy was moving so much and grunting with each hit tag Severus had to use one arm around the boy’s waist to hold him up.

“P-p-please, sir!” Harry gasped.

SLAP

SLAP

SLAP

SLAP

Severus didn't let up and continued to spank the tiny teenage penis. Harry was now crying, tears streaming down his face. Severus wanted to lick them off.

“What is your crime?” Severus hissed, not missing a beat in his assault of the cocklet.

SLAP

SLAP

SLAP

“What is your crime?” He repeated.

“I don't n-n-know!’ Harry wailed.

Severus stopped his cock spanking and grabbed it instead, squeezing tightly.

“You came without permission,” he snarled in the boy’s ear. “How many times do I have to tell you that you have foregone your rights as a young adult and are no longer in charge of your baby cocklet? If you know you aren't allowed to pass urine yourself, and you aren't allowed to touch your pathetic excuse for a cock, why on earth would you think you would be allowed to come without my express permission?”

“I'm s-sorry! Please! I'm so sorry, sir! I didn't know! Please! Please!”

Severus loved watching the small boy beg. His tears were flowing so much they covered his bare chest. His nose was snotty and his eyes were scrunched shut.

Severus gave one more squeeze to the cocklet, eliciting a further gasp of pain, and then released it and began caressing the boy’s cock and balls again, as though he hadn't just abused them.

Harry slowly began to calm down as his cock was massaged. It was double the size of normal from the swelling, as well as being bright red.

Aware the boy wouldn't be able to take much more, Severus summoned the healing ointment and used it as lube to wank the boy off again. He whimpered as his cock began filling for the third time in less than an hour, and still before breakfast.

“I'm going to reinsert the sound,” Severus said. Harry gave no reaction and just continued to cry quietly while leaning back against Severus’s hard body. “You clearly have not learnt self control yet, so you will keep it in all day and come see me this evening after dinner if you need to pass urine. Do you understand?”

Harry said nothing, resigned to accepting his fate.

“Do you understand?” Severus repeated as he lubed up the metal rod and pressed the cold end to the slit at the tip of Harry’s baby cocklet.

“I understand, sir,” Harry whispered, took exhausted and overwhelmed to speak louder.

Severus slowly inserted the sound and Harry gave no reaction, just taking it. Severus longed for the day he could fuck the boy's arsehole and he would take it just as compliantly.

Once it was fully inserted, Severus spelled it stuck again, aware the boy was probably at the limit of what he could take.

He moved away from Harry and Harry seemed to come back to reality as he stood independently. Severus nodded at the boy as he resumed his seat behind the desk.

Harry dressed slowly, taking care not to touch his sore penis.

“Please may I go now, sir?” Harry’s small subdued voice forced Severus to look up. His eyes were red and puffy from crying and he looked thoroughly miserable.

“Yes,” Severus replied. “Don't forget to come here after dinner if you would like to pass urine again. And if you're desperate you can find me at any point today and I will make a decision about whether to let you urinate early or not.

“Thank you, sir,” Harry said, turning to leave. At the door he paused and turned back to Severus. In his small subdued voice he said, “I really am sorry about not asking permission to come, sir. I promise I really was trying to be good.”

With that Harry quickly left the room, shutting the door behind him and giving Severus hope that Harry might just be an excellent submissive painslut, if only Severus could train him right.

Notes:

More kinks and eventually anal sex/penetration will be coming up as Snape carries on teaching Harry how to obey.

Chapter Text

The next week passed in a blur for Harry. He continued attending class and hanging out with Ron and Hermione, except the whole time he had a metal rod plugging his urethra.

 

 

After a few days he had got used to the feeling of fullness, as well as the jolt of pain whenever he walked or, worse, climbed stairs or ran. He had even been out flying twice. The first time he'd only lasted 15 minutes before the pain from the rod twisting in his penis against the wooden broom became too much to handle.

 

Harry was so used to this pain he didn't really class it as pain anymore. He thought of it more like a sensation. A sensation which he couldn't go more than a few minutes without feeling.

 

He visited Snape twice a day and they went through the same ritual. Harry would strip naked the second the dungeon door closed and then would wait patiently until Snape held his tiny cocklet and allowed him to piss in the metal bucket.

 

Harry grew to anticipate these sessions. He tried to tell himself it was fear but he knew it wasn't. He now associated these sessions with relief - his bladder was always so full that there was something calming about being able to release it. Of course he didn't know that Snape was slipping him diuretic potions in his pumpkin juice, hence his constant need to urinate.

 

These sessions were also the only time his small penis was touched. After the first time Snape had spanked his baby cocklet Harry had not touched his cock or balls once. He would occasionally rearrange himself but his hand would always be over the top of his pants. He didn't want to give Snape any excuse to punish his baby cocklet again.

 

Of course that wasn't to be the case. During almost every session Harry had to endure some kind of punishment for varying infractions. His bum had been spanked raw another four times, and his balls had been painfully squeezed during every session. He had been wanked and edged six times, but had been allowed to orgasm five more. Each wanking was getting rougher and always involved mistreatment of his balls.

 

One day in the Library Harry was reading an obscure charms textbook Hermione had lent him for some homework. He came across a charm which said it could unstick anything. Without thinking of the consequences, Harry made a note of it and ran to the nearest bathroom. He locked himself in a stall and pulled his trousers and pants down, looking at his flaccid cock with the flat metal end of the sound stuck to head.

 

It took him twelve attempts but finally the counter-charm worked and he was able to slip the sound out his penis. His cocklet hardened as the metal slipped out the urethra, as it had been trained to do by Snape. 

 

Without thinking, Harry quickly urinated (in a toilet for the first time in a week!) and then immediately began wanking himself raw. He came twice in the cubicle before cleaning his cocklet with tissue paper and pulling up his pants. Pocketing the sound he returned to Hermione in the Library.

 

That night before bed Harry started panicking. Snape would be suspicious if he didn't turn up desperate to have a wee. Harry quickly started drinking as much water as he could, alarming Ron and Hermione with his apparently unquenchable thirst. He quickly ran to the bathroom and wanked his already-raw cock hard. Unfortunately the fourteen year old didn't have any lube to hand, and didn't know the spell Snape usually used as he always cast it wordlessly. Harry quickly ran the sound under the tap, splashing as much water as he could over it and inserted it into his tiny penis. 

 

Luckily for Harry his cocklet was now used to the metal rod and accepted the intruder easily, as if welcoming it home. Harry cast a simple sticking charm and pulled up his trousers and pants before running to the dungeon.

 

Harry tried to look casual as he waited, stark naked, for Snape to look up.

 

Severus pretending to be reading a parchment and left the boy squirming for longer. Harry was a fool if he thought that Severus hadn't charmed the sound. He had, of course, been alerted the moment Harry had removed it, and he knew exactly when Harry had reinserted it - barely ten minutes ago.

 

Severus knew he was going to have to act angry, but he was currently so overjoyed at Harry’s blatant rule breaking that it was taking a lot of his self control to keep his face impassive.

 

Eventually Severus looked up.

 

“Please, sir, please can I pass urine?” Harry asked, doing his best impression of someone desperate for the loo and moving weight from one leg to the other.

 

Severus walked around the desk and stood behind Harry as usual, casting the invisible binding charm. He started wanking the boy, rougher and more aggressive than ever before. Harry didn't complain. Severus unstuck the sound and yanked it out, drawing a gasp from Harry at the rough treatment. He conjured the metal bucket and aimed the baby cocklet.

 

“You may urinate now,” Severus commanded.

 

It took more than a few seconds but eventually a small spurt of urine left the cocklet. It was barely anything, it couldn't even make a proper stream. And then it dribbled and stopped. 

 

Harry’s heart sank.

 

Severus let go of the tiny penis and walked so that he was facing Harry.

 

“Mr Potter, it appears you don't have any urine in your bladder,” Severus said softly. Harry flinched at the calmness and looked at the ground. He stayed silent.

 

“Mr Potter, why do you not have any urine in your bladder?”

 

Harry stole a glance up and wished he hadn't as those dark eyes were filled with fire. 

 

“I-I don't know, sir,” Harry whispered.

 

“You don't know?” Severus was seething. “You don't know why you have an empty bladder this evening?”

 

Harry shook his head.

 

SLAP

 

Severus smacked the boy’s cheek, leaving a large red handprint. Harry, shocked by the sudden violence, fell to the floor clutching the side of his face. Tears started falling, more due to fear of having been caught than the pain from the slap.

 

Severus bent down and grabbed Harry by his hair tightly. He forced the boy’s head up until his neck was extended so far his torso also started to bend backwards. 

 

“I know you removed the sound and touched your baby cocklet,” Snape hissed quietly in his ear. “I know you've been a filthy, dirty, bad boy. I've put so much effort into teaching you how to control yourself but you just can't, can you? Not even spanking your arse until it's bruised or battering your tiny balls or plugging your baby cocklet can teach you how to behave. You're beyond hope, Mr Potter, and I give up.”

 

With that he shoved Harry back down onto the floor where he continued to cry and whimper.

 

Severus strode away from him and Harry stayed on a heap on the floor.

 

Angrily Severus turned around and shouted at the boy, “get up you useless child! Leave my classroom at once!”

 

Harry continued to whimper and not move so Severus threw a stinging hex. Harry jolted at the pain but stayed on the ground. Severus threw another one and another until Harry was jerking from the pain and small red welts were appearing all over his naked body.

 

“P-p-please, sir!” Harry sobbed, eventually moving into a kneeling position and looking at Severus. “What- what will happen now?”

 

“Now?” Severus snarled. “Now you will leave my classroom. And then I shall inform the Headmaster and Professor McGonagall of your hideous behaviour and leave it with them.”

 

Harry looked alarmed. “What will they do?”

 

“How am I supposed to know what they'll do with a Triwizard champion who cannot control his bladder and has the self-control of a toddler? I would expect expulsion, unless either Dumbledore or McGonagall wants to try to train your tiny baby cocklet, but I wouldn't put much hope in either of them wanting to touch such a disgusting little boy like you. Filth,” Severus spat.

 

Harry trembled on the ground. He was ashamed of his tiny penis. Ashamed of his lack of control. How could he face Dumbledore and McGonagall, two adults he admired and respected, and let them know about his problems urinating or controlling himself? What if they saw him naked? What if they had to touch his baby cocklet? Harry shuddered. He couldn't do that. No matter what, he couldn't let Dumbledore and McGonagall know. He wouldn't be able to bear to see their disgusted faces when they learned how despicable he truly was.

 

“Please, sir,” Harry whispered. “Please don't tell them. I-I promise to be good.”

 

Snape huffed a laugh.

 

“I promise to be better. Please, please don't tell them.”

 

“I don't have a choice, Mr Potter. There is no other option left.”

 

Harry moved forwards. He was still on his knees but now as upright as possible.

 

“You can teach me. I know I’ve been bad today and I don't deserve it. But you've been teaching me so well. And there's still more to learn. You can do anything you need to do to teach me how to behave. I promise l’ll learn this time. I promise to listen and obey and do anything you say. I promise I can be good. Please let me prove I can be good. Please, sir.”

 

Harry looked up at his potions master beseechingly.

 

Severus pretended to hesitate and ponder the suggestion. He sighed and looked at the naked boy kneeling on the ground in front of him.

 

“There would be conditions.”

 

Harry’s eyes looked brighter and he nodded in understanding.

 

“I will outline the conditions and then you can have the choice of whether you are willing to accept them, or if you would rather your punishment was handed over to Dumbledore and McGonagall.”

 

Harry nodded, knowing there was no way in hell he would agree to Dumbledore and McGonagall; he would be accepting anything Snape said.

 

“First, since you have no self-control I will be taking full control. You would be agreeing to hand me full control of your body and mind, to do with as I please. In essence it will be like I am your Master. And you will be like a slave, unable to do anything without my express permission, and completely at my whim, no matter how unfair or painful or unpleasant that whim may be to you. Do you understand?”

 

Harry didn't like the sound of that, but he had no choice. 

 

“Yes, sir,” he said, willingly giving up his body and mind to the full control of his potions professor.

 

“Second, you will be punished regularly until you learn how to behave like a good boy consistently. Three times a week you will come to my quarters for punishment. You will not complain about your punishments. You will not ask or beg to forgo a punishment. You will accept them graciously and thank me for them, knowing as you do that you require a hands-on approach to fix your delinquency.”

 

“Yes, sir,” Harry said.

 

“Third, you will experience pain, humiliation and degradation. You will not complain about these. You will do as as I say on the first instruction. You will not hesitate. Any feelings you have of pain or shame are not important. You are not important.”

 

“Yes, sir.”

 

“Fourth, if I desire pleasure I shall take it. Your pleasure or satisfaction is not important, because you are a child who cannot control himself and who behaves abysmally. Given that I am going out of my way to give you a favour here, you will prioritise my pleasure. Even if you are tired or in pain or don't want to. Your number one priority will be me, and making me happy. Do you understand?”

 

“Yes, sir, I shall prioritise you and your pleasure. My own isn't important.”

 

“Good. And lastly, you will not ask questions. About your punishments or anything at all. Little boys don't get to ask questions. That is a privilege for adults.” 

 

“Yes, sir.”

 

“Do you, Harry James Potter, accept all of these conditions and consent to me being your Master of Punishments?”

 

Harry looked up at Snape. Aware that the might regret this, but not seeing any other option he nodded. “Yes, sir, I consent to you being my Master of Punishments.”

 

Severus was positively gleeful but he hid it behind a neutral mask. Harry Potter was now his teenage slave. He had so many plans! There were so many ways to destroy the boy. He thought again about slamming the boy face down to the ground and shoving his massive cock into his virgin arsehole dry and pummelling the boy until his hole was gaping. 

 

But no, Severus thought. He would have to work up to that. But that's no reason not to play with the boy’s hole a little today.

 

“Given your terrible behaviour with passing urine, I think we should go right back to basics. You have lost the right to control all of your bodily functions.”

 

Harry looked alarmed and opened his mouth as though he were about to protest or ask a question. Snape raised an eyebrow and his mouth shut.

 

“From now on you will not have control of your bowels either.”

 

Harry looked terrified.

 

“Bend over the desk.”

 

Harry stood up slowly and walked to one of the desks in the front row of the classroom. He bent over at the waist, like he had on the day of his first punishment, and pressed his cheek into the wood. His arms were still bound invisibly behind his back.

 

Severus stood behind him and grabbed each globe of his arsecheeks with each hand, separating them in the middle until he could see that tiny virginal pucker.

 

He started massaging the outside with his index finger and felt Harry reflexively clench it even more.

 

“Have you ever put anything in here?” Snape asked.

 

“N-no, sir,” Harry whimpered.

 

Severus was struggling to access the boy’s anus as his bum was nice and bouncy and he was clenching his bum cheeks in fear. Snape slapped the right bum cheek.

 

“One, thank you for punishing me, Professor Snape.”

 

Severus suppressed a laugh. He hadn't told the boy to do that, but he was impressed by Harry’s initiative.

Severus enjoyed the boy squirming and the pinking of his arse cheeks. He continued to massage them and slowly felt the boy relaxing under his touch.

 

Severus wanted better access to Harry’s hole, so he repositioned the boy until he was kneeling on the desk with his face pressed to the wood as his arms were still bound. He then made the boy lower himself until he was in a frog pose. It seemed quite easy for the boy and Severus was gleeful at the boy’s flexibility. 

 

The boyishly tight ball sack was hanging down and touching the desk, his tiny penis hidden from view. Severis started caressing the boy’s balls with his left hand in his usual harsh way of mixing it squeezes and tugs and twists. With his right hand he continued circling the boy’s pucker, which was now completely on display between the boy’s spread arsecheeks.

 

Harry squirmed as he felt his baby cocklet stiffen under the familiar touch of his professor. He gave into the sensations and even started liking the pressure at his anus. He knew the anus could be used in sex, because he had heard the boys in Gryffindor talking about it, but he hadn't known it could be boy’s anus that was used. He supposed they only really talked about girls.

 

Harry gasped as he felt something wet at his entrance. He heard Snape telling him to relax and that everything would be better if he relaxed because this was happening whether he relaxed or didn't. Harry tried to take deep breaths.

 

Suddenly he was breached. Harry jolted as what felt like Snape’s finger entered his hole in one smooth motion, all the way up to the knuckle. It wasn't painful - at least not compared to the spankings Harry had had - but it felt odd, like an intruder.

 

Snape started twisting and thrusting his finger in and out. After less than a minute he inserted a second finger. It went in suddenly and all the way.

 

Harry gasped and shook. His arsehole was burning with the stretch. He wanted to teach behind him and take the fingers out but his hands were bound. He bit down on his lip to stop himself from shouting at Snape to take it out of him. He knew he had to do anything Snape wanted, so he lay there and took it and Snape thrusted his fingers in and out of Harry’s swollen hole.

 

Barely a minute later Snape added a third finger and Harry did cry out with a sob. 

 

“No, sir, please, please, it hurts,” Harry babbled as he felt his arsehole burning.

Snape pulled out his fingers and rained down spanks on Harry’s bum, changing his primary pain from burning to stinging. Harry only just remembered to thank Snape. He was sobbing with tears falling down his cheeks.

 

Snape reapplied lube and thrust the three fingers straight back into Harry, mercilessly fucking him with them. With his left hand he grabbed Harry’s balls and returned to twisting and squeezing and caressing and pulling them.

 

After a while Harry noticed he was rock hard again and he became aware that the pain had subsided. This was when he felt a sudden jolt like lightning through him. 

 

“Sir- please- I'm going to come!” Harry cried, too far gone in the sensation to care what he was saying.

 

Severus immediately stopped his ministrations and grabbed the base of the boy’s baby cocklet, squeezing it harshly until Harry was crying out from both the pain of having his cock squeezed as well as the pain of having been brought down from the edge of orgasm.

 

When he seemed to be coping better, Snape spanked his ball sack.

“You do not tell me when you are about to come, you ask permission , you filthy, uncontrollable, whore!” Snape's hissed as he spanked the oversensitive balls on each word for emphasis.

 

Harry sobbed harder as he was overwhelmed by the pain in his testicles. They felt battered and bruised although they were only slightly swollen and bright red. 

 

Severus summoned a silicon butt plug from his desk that he had been keeping just for Harry. It was about an inch and a half wide at the widest point, and the flared base had a green emerald in it. Severus had imagined the raven haired boy with the green eyes wearing the matching Slytherin-themed butt plug many times in his fantasies.

 

Severus lubed up the plug and shoved it into Harry’s hole. Harry howled in pain as it reached the widest point, the burning in his arsehole overtaking the throbbing in his balls in his attention. 

 

Severus twisted and slowly pumped it repetitively about a centimetre until he felt the muscle give and the plug slid in fully and settled inside the teenager.

 

The boy was lost in his sobs, so Severus activated the vibration charmed and once again started caressing the boy’s balls. 

 

“It’s okay, Harry, you did so well,” Severus said soothingly. “You took it so well and it's almost over. Such a good boy.”

 

The sobs started slowing down and stuttering as Harry felt the plug vibrating against his prostate. It didn't take long for his cock to get hard again.

 

Severus helped pull him up to standing so the boy’s back was against Severus’s front. The boy was hiccuping and his face was streaked with tears but he was much calmer.

 

“There, there, Harry. Such a good boy,” Severus soothed as he wrapped his left arm around the boy’s waist and started wanking the boy’s baby cocklet with his right hand.

 

Harry knew better, of course, but in that moment it almost felt as though Snape was hugging him. Harry lent into the touch, into the strong, tall, masculine body behind him, content that right in this moment nothing was required of him.

 

When Harry’s cocklet twitched with the need to orgasm, Severus let go. He continued muttering reassurances in the boy's ear as he lubed up the sound and reinserted it into Harry’s urethra, sticking it in place. 

 

“Do you want me to ice your baby cocklet down again?” Severus asked in a whisper to Harry’s ear.

 

“Y-yes, please, sir,” Harry said, knowing his cocklet needed to deflated and not trusting himself to manage it when left alone.

 

Severus quietly conjured the ice and Harry hissed as it touched his swollen, throbbing penis with a pain that was both burning and stinging.

 

When the baby cocklet was once again flaccid, Severus wrapped both arms around the boy’s waist and pressed a kiss into the base of his neck. Harry lent into the touch of affection.

 

“It's all over, Harry. You can get dressed now.”

 

Slowly Harry began to open his eyes. He could feel the sound in his urethra, but he was so used to it by now it didn't bother him. He could also feel the heavy plug lodged in his rectum. It felt strange and uncomfortable but it wasn't painful anymore. The vibrations had stopped.

 

Harry slowly stepped away from Snape and put his clothes back on. Snape watched him hungrily.

 

“Mr Potter,” Snape said, reverting to his businesslike voice, “I trust you won't forget our arrangement.”

 

“I won't, sir,” Harry said, looking down.

 

“You will not touch your baby cocklet. You will not remove the sound or the plug. You will come to my quarters tomorrow morning, rather than this classroom, and I will tend to any physical needs you have. Do you understand?”

 

“Yes, sir,” Harry said, glancing up at him.

 

“What do you say, Mr Potter?”

 

Harry looked confused for a second, and then it clicked.

 

“Thank you for punishing me, Professor Snape. I promise l’ll be good and obey this time.”

 

With that, Snape dismissed the boy and as Harry left the classroom Snape sat at his desk and pulled a piece of parchment out, planning everything he wanted to do to the teenager while masturbating his own cock under the desk.

Chapter Text

Harry could feel the butt plug inside his anus all night. It pressed against his walls whenever he moved or walked. And sometimes it would press against something that would give Harry a jolt of pleasure.

 

The next morning Harry woke early and made his way to Snape’s quarters. The potions master opened the door, revealing an open plan kitchen-living room. Snape made Harry strip as soon as the door was closed, and then made Harry bend over with his palms against the door as Snape made sure the butt plug was still present. 

 

When he was satisfied he brought Harry to what Harry assumed had probably been a guest bedroom, but was now an empty room with just a raised platform in the centre. Snape conjured a porcelain bathtub on the platform and made Harry get inside and kneel on all fours. 

 

When he was in place Severus cast a sticking charm to stick Harry’s hands and knees to the base of the bathtub, preventing Harry from moving. 

 

Severus began examining the butt plug and started twisting it. Harry winced in discomfort but said nothing. Severus pulled on the base but it seemed stuck inside Harry’s tight virginal hole. Harry made noises of pain on each attempt but Severus didn't pay them any attention. He cast a wandless lubrication charm and then pulled the plug with force, popping it out Harry’s hole.

 

Harry screamed in pain and started sobbing, “no, no, please, it's torn my hole, oh God, oh God.”

 

“Shut up you filthy slut,” Severus snapped. “I didn't give you permission to speak.”

 

Harry whimpered silently as Severus examined the boy’s hole. He was right, there was a tear in Harry’s rim. Severus cast a healing charm and it immediately closed. Harry’s whimpers died down. 

 

Severus lubed up his fingers and thrust three straight into Harry’s anus, knuckle deep. The boy howled at the burning stretch and tears fell splashing against the bathtub. Severus pumped his fingers in and out, making sure to hit Harry’s prostate. He was rewarded when he saw the baby cocklet start to get hard.

Severus couldn't resist spanking that tiny penis and the smooth balls that accompanied it.

He took his fingers out Harry’s hole and pelted the cock and balls with hard smacks until Harry’s arms gave way and his head lowered into the bathtub. Severus was delighted to see the cocklet remained semi-hard throughout the assault.

 

Severus then lubed up the tip of a nozzle and inserted it into the child’s rectum. Harry just sobbed quietly while Severus hooked the tubing up to a bag of fluid handing from a drip stand. He cast a charm that caused the bag to squeeze, slowly filling Harry’s insides with water.

 

Harry remained silent until almost half a litre of water had entered him and then he started squirming.

 

“Please, sir, please, I don't think I can take anymore.”

 

Harry could feel the water slowly filling his bowels and it was stretching him uncomfortably. It was a burning ache that soon gave way to cramps. He felt as though he needed to have an explosive motion but he was terrified of having to do it in front of Snape. His cocklet was now completely flaccid.

 

“Oh God, please sir! Please make it stop. I can't take it!” Harry gasped.

 

“You will shut up and take it or I will muzzle you like a dog,” Severus threatened. 

 

Harry continued to write but dutifully stopped complaining. As the volume got close to a litre he broke out pleading again. He felt like his insides would burst. He would take a hundred spanks to his baby cocklet if the alternative was this. 

 

“Please, sir, plea-”

 

Harry was cut off by a ball gag that was conjured into his mouth. Severus came round to Harry’s front and watched the tears streaming down his face as he continued to try and wordlessly plead, his mouth held open and wrapped around the ball gag. Severus had to press the palm of his hand to his own cock to stop himself coming at the sight.

 

Severus leaned forward and pinched Harry’s nipple. Harry gasped but Severus noticed his tiny penis starting to fill again. Severus took a nipple in each hand and began twisting and pinching and pulling them. Soon they were a dark red, just beginning to purple. The baby cocklet continued to fill. 

 

The bag was finally empty and so Severus, with a quick slap to Harry's tear soaked cheek, got up and removed the nozzle.

 

“You will keep the water inside you until I tell you to release it,” Severus commanded, knowing the impossibility of the task.

 

Harry tensed and strained with the effort of keeping that much water inside him. He panted and squirmed but it was all to no avail. Eventually his sphincter gave way and the water exploded from his anus. He began to cry at having failed his task.

 

Severus knelt down by Harry’s face.

 

“Tsk, tsk,” he said quietly, stroking Harry’s cheek. “Aren't you just a filthy little dirty boy with no self control?”

 

Harry sobbed again.

 

“Shh, don't worry, little boy,” Severus soothed. “What's done is done so just let it all out now. You're due a punishment tomorrow night anyway, so why don't we deal with this little mishap then, hm?”

 

Harry shuddered and nodded his head, leaning into the comforting touch on his cheek. 

 

When all the water had been expelled, Severus conjured a shower head and rinsed the boy. Then he returned his attention to Harry’s now-clean hole. He applied more lube and thrust his three fingers in again and kept going until the boy was hard. Just when Harry started rocking back on his fingers and moaning in pleasure, Severus withdrew them and spanked Harry’s bum cheek, causing him to flinch in pain.

 

Severus released the sticking charm, vanished the ball gag, and helped Harry out the tub, wrapping him a fluffy towel and hugging the boy as Harry buried his head into Severus’s chest. 

 

Harry groaned.

 

“Are you okay, Harry?” Severus asked innocently. “Is there something you need?” 

 

Harry just nuzzled his head further into that strong adult chest. 

 

“You need to use your words, Harry.”

 

It took a moment for Harry to gather the courage but soon he said, very quietly, “I need to wee and come.”

 

“Okay, Harry,” Severus said simply, still hugging the boy.

 

He conjured a black leather sofa on one side of the room and then picked the boy up so Harry had to wrap his legs around Severus’s waist. Harry didn't complain as Severus carried him like a child over to the sofa, one hand around his waist and the other on his bum. 

 

Severus gently lay Harry on the sofa and vanished the towel. He pushed Harry’s legs up until one was over the back of the sofa and the other was in the air. Severus sat himself down and turned to face Harry. He could see the boy’s head resting on the armrest and looking at him with innocent yet dilated eyes. He could see the boy’s naked body ending in his tiny red and bruised cocklet and balls. The recently abused hole was on full display, still open and trying to clench around nothing.

 

Severus conjured more lube and reinserted his three fingers, causing Harry to gasp and moan and push down against his teacher’s hand. Severus continued to fuck the boy with his fingers, thrusting in harder and harder, losing himself in Harry’s whimpers.

 

Severus conjured even more lube and grabbed Harry’s baby cocklet, roughly tugging it in rhythm with his thrusts. The boy grabbed underneath both his knees and pulled them to his chest, silently giving Severus better access to his penis, balls and anus. 

 

Unable to resist, Severus cast a wandless unsticking charm and bent down to pull the metal sound out Harry's tiny penis with his teeth. The boy jerked as the metal rod was removed.

 

Severus spat it on the floor and then went straight back, licking the head of the boy’s tiny cocklet and then swallowing the whole thing in one, sucking hard on the miniscule member.

 

“Please, sir!” Harry gasped, “Please can I come? I need to come, oh please! Please can I come, sir?” Harry was babbling and lost in the many sensations wracking his tiny frame.

 

Severus pulled off the baby cocklet and watched Harry’s scrunched up face.

 

“Yes, Harry, come for me now.”

 

Severus watched in awe as the boy jerked and rope after rope of come exploded from the tiny penis that looked like it shouldn't be able to hold anywhere near that much come. It landed on Harry’s stomach and all over Severus’s hand. Hee continued to pump his fingers into Harry’s anus, causing the boy to write from oversensitivity.

 

Suddenly Severus pressed down hard on Harry’s lower stomach and urine shot out the boy’s slit, coating Harry in his own pee. The warm water flowed and flowed. It formed a river and ran up Harry’s chest, pooling around his neck and running down onto his back. It coated what little pubic hair he had and Severus relished the drip drip drip of it running off the leather and onto the floor. 

 

When the flow finally stopped Harry and Severus were both lying in a puddle of rapidly cooling urine. 

 

“I'm sorry, sir, I’m sorry, I-”

 

Severus cut the boy off by reaching down licking the come, now drenched in a puddle of urine, off Harry’s stomach. Harry froze, but Severus continued until he had tasted every drop of Harry’s come and had licked up plenty of teenage urine. 

 

When he resurfaced his face was covered in Harry’s pee and he slowly moved towards the boy, dropping down and kissing him on the mouth. Harry only hesitated for a second before opening his mouth and accepting the tongue of his professor into the warm cavern. He could taste his own come and urine on his teacher’s tongue.

 

While Severus plundered the boy’s mouth he began wanking his tiny cocklet off again. Harry squirmed but Severus used his other hand to twist the boy’s balls harshly, causing Harry to gasp in pain.

 

When the boy was fully hard Severus withdrew and conjured another sound. This one was wider than the first and Harry eyed it apprehensively. 

 

Severus lubed it up and slowly pushed it into the boy’s slit, causing him to writhe in pain as his urethra was dilated once again. 

 

Once Severus had stuck the new one down, he made Harry stand in the bathtub again. Picking up the shower head Severus aimed it at the boy and magically turned the water to 5 degrees celsius and sprayed Harry with freezing cold water, shocking Harry’s body with icy lashes of pain.

 

The boy cried and whimpered but allowed his professor to rinse of the urine and come, and even tolerated Snape’s prolonged rinsing of his tiny cock and balls, which shriveled up in the freezing cold. It was agony.

 

When Severus was done he left Harry standing in the bathtub shivering while he summoned a new piece of equipment.

 

It was a little metal cock cage and Severus placed it over Harry’s now-impossibly-smaller baby cocklet, spelling it closed and shrinking it until it fit snuggly. He then helped Harry out the tub and wrapped another towel around him, pulling him close and kissing the top of his head while whispering that he had been such a good little boy. 

 

 

Eventually Severus allowed him to dress and head down to breakfast, counting down the hours until Harry’s ‘punishment’ sessions began.

Chapter Text

The following night Severus sat in his armchair, counting down the minutes until Harry arrived for the first of his punishment lessons. Severus had spent the last two days preparing everything and was thoroughly excited to begin properly abusing the boy, though he kept on a mask of cool indifference.

 

At eight o’clock there was a knock on the door. Severus opened the door, silently directing Harry into his quarters, and then resumed his seat in the armchair. 

 

Harry, knowing what to do, stripped naked as soon as he was in the room and knelt down in front of the fireplace with his knees spread and hands behind his back. He made sure to divert his gaze and look down at Severus’s shoes.

 

Severus was positively gleeful at how submissive Harry had become in such a short space of time. Twice a day Severus was removing the sound to let Harry pee, and this morning he had given Harry his second enema. Severus could easily spell everything away, but he liked Harry’s humiliation too much to stop. Plus, he thought, the enema was providing good stretching practice for Harry’s rectum and bowel.

 

“How was school today, Harry?” Severus asked.

 

“Good, sir,” Harry said, still looking down. “Thank you for asking, sir.” 

 

“Have you touched your baby cocklet today, or had any accidents or behaviour issues?” 

 

“I haven't touched myself, sir, or had any accidents. But Professor Flitwick had to tell me off in charms for talking during class.”

 

Harry’s cheeks pinked at the admission. 

 

“We’ll have to add that to the punishment list.”

 

“Yes, sir,” Harry said. “Thank you, sir,” he added, making Severus's cock twitch.

 

“List the crimes you will be punished for today.”

 

“First is my normal punishment, sir,” Harry said, still looking at the ground. “Second is the punishment for not keeping the water in my hole yesterday. Third is the punishment for urinating without permission yesterday. Fourth is the punishment for Professor Flitwick having to tell me off in class today.”

 

“Good boy,” Severus said with a smile. “Come here.”

 

Severus held out his hand and indicated with his fingers for Harry to come close. Harry began to stand but Severus interrupted.

 

“No, Harry,” he said and Harry became flustered, briefly glancing at Severus before returning to his kneeling submissive pose. “Standing and walking is for adults. You’re a child with behaviour issues. How do children move around, Harry?” Severus was smirking.

 

“Er,” Harry said. “They crawl?”

 

“Exactly,” Severus said, making the hand gesture again. “Come here, little boy.”

 

Harry put his hands down and moved onto all fours. He tentatively started crawling across the carpet, eyes fixed on Severus’s hand. When he arrived he sat back on his heels and returned his hands to behind his back.

 

Severus reached out and threaded his fingers through the boy’s mop of black curly hair, pushing his hair off his forehead. He continued stroking Harry’s hair, almost like petting a dog.

 

“Good boy,” he said, relishing in the blush that filled Harry’s face at the words.

 

“I hope you realise that you deserve these punishments, Harry,” Severus said with a raised eyebrow.

 

“Yes, sir, I know I deserve them.”

 

“And do you think I am being good to you in helping you learn how to behave? Do you think I'm being fair?” Severus asked. “You can look at me,” he added.

 

Harry looked up at his potion’s master, taking in the hooked nose and the long black hair.

 

“Yes, sir, I’m very grateful you are taking the time to teach me things I should have learned as a child,” Harry said, and Severus struggled to detect any lie or sarcasm. “I think you are being very fair, sir.”

 

“Good, Harry,” Severus said, still stroking the boy’s hair. “And to further demonstrate how fair I am, I shall not punish you for passing urine without permission yesterday.”

 

Harry’s eyes widened with hope.

 

“I recognise you had no control over that.”

 

“Thank you, sir!”

 

“So we have three punishments today. Would you like to get started?” Severus asked, his mouth curling into a smile.

 

“Yes, sir,” Harry said, nodding. “Thank you, sir.”

 

Severus stood up and walked to the spare room. He was delighted when Harry crawled along behind him without having to be told.

 

The room had been updated since Harry’s last visit. The leather sofa remained against one wall, but there were now objects attached to another wall next to a large chest of drawers. The middle platform now contained a large wooden cross, in the shape of a St Andrew’s cross. 

 

Severus walked to the cross and watched as Harry crawled behind him, stepping up onto the platform like a dog. Severus pulled Harry up and manoeuvred his limbs so they were each against an arm of the wooden structure, with Harry’s bum against the wood. 

 

When Harry was in place Severus cast a sticking charm on each limb to keep it there. He now had complete access to the front of the naked boy. His eyes trailed down and he looked at the tiny cocklet encased in its metal cage, sitting on Harry’s smooth balls. It took all of Severus’s willpower to not touch or pinch or yank them.

 

Instead Severus took each of Harry’s nipples into his hands, pinching and pulling them between the thumb and forefinger. Harry looked down and remained silent.

 

“Look at me during your punishment, Harry,” Severus said softly.

 

Harry’s eyes immediately snapped up. 

 

Severus continued touching and twisting and pulling the teenage nipples as he watched Harry’s eyes grow darker. He increased force until Harry was wincing from the pain.

 

Harry felt the pain in his nipples go straight to his cocklet. Unfortunately his penis was caged and there was no chance of him getting hard. He started to squirm as he felt a growing arousal that he couldn't find any satisfaction from. Each jolt of pain shot to his crotch and he started squeezing his arsecheeks together, trying not to focus on how much he wanted Severus's fingers inside his arsehole again.

 

This whole thing was so confusing to Harry. He went from at times hating Snape, to finding himself almost craving the man. He wanted Snape to finger his arsehole again. He wanted Snape to suck his baby cocklet again. He wasn't even averse to the kissing. 

 

Harry began whimpering as his nipples swelled up, growing red and puffy under Snape’s ministrations. He found it painful but he equally didn't want it to stop. Harry continued to watch Snape. He was wearing an expression of complete concentration, as though torturing Harry’s nipples was the sole aim of his life. 

 

Harry felt a sudden fluttering in his stomach that wasn't from the pain. He continued to look at the teacher who was giving Harry his undivided attention. Harry had never had anyone’s undivided attention. But here Snape was, acting as if Harry were the only thing of importance in the universe.

 

Severus gave a final harsh twist of Harry’s nipples and was rewarded with a gasp and the first tear drop of the session. Severus released the burning hot nipples and, unable to resist, leaned in and licked the tear track off Harry’s face, from jaw to eyelid. Harry gasped.

 

Severus stepped back and conjured something that, to Harry, looked like two bulldog clips with a rubber coating. Severus moved forwards and attached the clamp of one to Harry’s right nipple. Harry felt a throbbing pain and began breathing heavily as the clamp was tightened on his already sore and sensitive nipple.

 

Severus repeated the same for the left nipple and then took out two small hooks, attaching each one to each clamp.

 

Harry shut his eyes as the pain grew. A further tear escaped, but he forced himself to stay silent. This was his punishment and he would prove he could take it like an adult. He would not resort to screaming like a child.

 

Once both hooks were on Severus conjured two small metal balls, each attached to a short chain. He wasted no time in attaching each to one of the hooks.

 

It became immediately apparent to Harry that these were weights. His nipples were pulled down impossibly low and he felt as though they might be pulled off altogether. It felt like the blood supply to his nipples had been stopped and they were dying. 

 

Tears started streaming down Harry’s face. Severus licked on again, relishing the taste of salty water from the crying boy. He stepped close and placed a hand over Harry’s jaw, feeling Harry lean into it subconsciously. He placed a kiss to the boy’s temple.

 

“Can you take more, Harry?” he whispered in the boy’s ear.

 

Harry let out a sob and further tears fell. Severus didn't move, but stayed stroking his thumb along Harry’s cheek and intermittently licking and kissing his temple.

 

Eventually Harry nodded, unsure why but desperate to please this man.

 

“Use your words, Harry,” Severus said softly.

 

“Y-y-yes, s-sir,” Harry whimpered. “I c-can take more.”

 

“Good boy,” Severus said and noticed Harry blush. “Such a good little boy for me.”

 

He stepped back and conjured two more balls. He attached them to each hook and Harry felt his nipples pull down even more. He began sobbing more forcefully and Severus soaked up the boy’s pain and cries.

 

“Well done, little boy, well done,” Severus soothed. 

 

He ran his thumbs over the sore nipples and felt the burning heat from them. They were almost doubled the size of when Severus started. Harry didn't seem to notice Severus caressing them, too far gone in the pain he was experiencing.

 

“Shall we move on to your second punishment, Harry?”

 

Harry’s heart dropped as he remembered there were more punishments coming. 

 

“Yes, s-sir,” he managed to say, knowing Severus would want a verbal answer. 

 

Any hope Harry had that Severus would remove the nipple clamps and weights before moving onto the second punishment were dashed when he unstuck Harry from the cross and helped him kneel down in front of it, still facing Severus.

 

Severus waited a few minutes until Harry’s crying slowed down, indicating the boy was adjusting to the level of pain from the clamps. 

 

“Look at me, Harry,” he commanded.

 

The boy looked up at his teacher, eyes red rimmed and tear streaks down his face, still whimpering slightly. 

 

“Do you want to make me happy, Harry?” Severus asked. “Answer truthfully.” 

 

Harry took a few seconds before he answered. He was in so much pain and felt so needy that he had no intention of lying. Severus caressed his cheek again and Harry felt another swoop of comfort at the touch.

 

“Yes, sir,” he said. “I want to make you happy, sir. I want to please you.”

 

Severus felt himself shudder at the boy’s open and clearly honest words. He couldn't wait to destroy him further.

 

“Good boy,” Severus muttered and he felt Harry preen. “Have you ever sucked a cock before?” 

 

Harry gasped.

 

“N-no, sir,” he said, eyes dropping down to stare at the large bulge in Severus’s trousers, which so happened to be right in front of his eyes. 

 

Severus stepped forward until his clothes cock was barely a centimetre away from the teenager’s nose.

 

“Would you like to?” he asked.

 

Harry looked up at the grown man through wet eyelashes. He moved his head forward and pressed a kiss to the zip of Severus’s trousers.

 

“Yes, sir,” Harry said. 

 

When Severus made no move, Harry added “please sir, please let me taste your cock.”

 

Severus had to take a few breaths before he could move. So much for the boy’s destruction; Severus felt like he was being slowly torn apart by this perfectly naturally submissive teenager.

 

“You're just a little slut, aren't you?” Severus sneered.

 

Harry stared up at him, mouth still pressed to Severus’s crotch. He nodded. Severus had to suppress a gasp.

 

“You're a filthy, dirty little boy, whose only good use is to take a real man’s cock,” Severus continued, unable to stop the abuse now it was coming. Harry just looked at him, eyes dilating as he was verbally degraded. “How pointless for you to go to class when all you'll ever be is the cock slut you truly are. I should make you walk around the hallways naked so anyone can take you at any moment. You'll be reduced to just your holes. It's a waste of air not to have you stuffed full of adult cock every moment you're alive.”

 

Harry shuddered but continued to mouth at Severus’s cock.

 

“Maybe I should tie you up naked in the Entrance Hall and charge everyone half a knut to fuck you raw. You'd love it the whole time and beg me for more. Who would you want to fuck you? Karkaroff? Moody? Cedric?”

 

Harry felt his baby cocklet straining against it's cage. He absolutely did not want to be publicly fucked - he'd never even been fucked at all! - but there was something about the scene Snape painted that made Harry want to do it. He wanted to be humiliated and degraded in front of others. He wanted Snape to be proud of how much cock and pain he could take.

 

Severus grabbed Harry by the hair and pulled him back with one hand. Harry gasped as his head was thrown back. 

 

Severus quickly used his other hand to drop his trousers and pants. His released cock immediately jutted out in front of him. Harry stared at it. It was massive.

 

The potions’s master’s cock was giant and a deep red and absolutely rock solid. It was so thick that Harry was sure his whole hand wouldn't be able to wrap around it.

 

Harry finally understood why Snape referred to his penis as a baby cocklet; Snape’s cock was about four times the length of Harry’s. 

 

Harry’s mouth watered involuntarily and his arsehole clenched around nothing. He could feel his nipples throbbing away with a pain that will still severe but somehow dulled. Instead his attention was mostly on his straining cocklet that wasn't able to get hard. He desperately wanted the cage removed so he could get his baby cocklet hard. He felt like he would come immediately upon its release.

 

SLAP

 

Snape slapped Harry across the face and he fell to the ground, the weights pulling harshly at his nipples as he became horizontal. Harry gasped in pain and tears began forming.

 

“Don't you dare touch your baby cocklet!” Snape hissed furiously. “You filthy, disgusting boy!”

 

Harry whimpered as he realised he must have touched his cocklet unconsciously. He slowly moved back onto his knees.

 

“I'm sorry, sir!” he gasped. “I'm sorry, I didn't mean to!”

 

“And that's why we're here, Mr Potter,” Snape sneered. “The self control of a toddler.”

 

Harry blinked away the tears that threatened to fall at having been chastised by the use of his last name. He had grown used to Snape calling him ‘Harry’ or even ‘little boy' and he didn't like the loss of comfort that come from Snape using his surname.

 

“I'm sorry, sir,” Harry whispered 

 

Snape threaded his fingers through Harry’s hair again and forced the boy’s face into his erect penis. 

 

“Lick,” he commanded.

 

Harry immediately stuck out his tongue and began licking the throbbing, heavy cock in front of him. He licked all up the shaft and then reached the head where he licked everywhere including in the slit, feeling the salty liquid on his tongue. Harry groaned at the taste of his professor’s precum.

 

Harry took the head into his mouth and began suckling like a baby animal. He pushed his tongue into the slit again and again.

 

Snape yanked his head back and Harry gasped as he was forcibly taken off the cock. Snape used the opportunity of his open mouth to shove his cock down the boy’s throat as far as it could go.

 

Harry gagged as he felt the giant cock move to the back of his tongue and hit the back of his throat. 

 

“Relax your throat, boy,” Severus said, too impatient to give Harry a chance to adjust. The boy only had a third of Severus’s cock in his mouth.

 

The boy continued to gag as his face turned bright red. Severus sighed and withdrew his cock. The boy gasped in lungfuls of air.

 

Severus, unwilling to take this slow, cast a throat relaxation charm and shoved his cock into the boy’s mouth again without warning. 

 

Harry’s throat opened up for the intruding cock, though he continued to struggle to breathe. Snape offered bits of advice, such as to breathe through his nose, but ultimately he didn't care - Harry would learn one way or the other.

 

Harry felt his throat burning as his professor’s cock pistoned into his throat. He quickly realised he would not get a reprieve from the onslaught and gradually figured he should breathe through his nose. The cock slid down into his throat, impossibly far, although Harry knew there was more of the cock to go that just simply couldn't fit in his teenage throat.

 

Like his previous punishments, Harry soon realised that accepting his fate and taking it would be better than trying to maintain some control. When he relaxed and allowed Snape to thrust relentlessly in and out of his mouth, pooling drool that dripped down his chin in long sticky streaks, he found that it wasn't so bad. The rhythm of it was almost relaxing and the pain in his throat was just pain - something which he was used to.

 

Harry instinctively brought his hand up to stroke along the base of the cock that couldn't fit in his mouth. When Snape groaned at his touch he continued with more confidence, bringing his other hand up when he realised the girth was too big for just one.

 

On and on it went with Snape thrusting in and out and in and out of Harry’s throat. Drool was covering his upper chest and dropping onto the nipple clamps with their weight. Harry could still feel the pain in his nipples, alongside the strain of his cocklet. His mind went blank as he was reduced to pure physical sensation, unable to comprehend school work or his friends or even the passing of time itself. It was just Harry and Snape’s giant cock.

 

Eventually the cock sped up and its thrusts grew more erratic. Harry could feel his professor’s heavy balls contract and then suddenly the cock was jerking and Snape’s come was filling his mouth.

 

“Swallow it,” Snape commanded.

 

Harry dutifully swallowed each drop and moved to lick the come residue off the tip of Snape’s cock. When he was done he sat back on his heels, his face a mess of dried tears and drool. 

 

“Filthy, messy boy,” Snape said looking down at the exhausted teen. “You need a shower, don't you?”

 

Harry looked up at Snape and nodded. Remembering he liked words Harry added, “yes, sir.” It came out hoarse and choked, and his throat burned as he spoke 

 

Snape smirked down at him and moved closer again, grabbing his own, now flaccid, cock.

 

Before Harry had a chance to register what was about to happen, Snape started pissing urine directly into Harry’s face.

 

Harry scrunched his eyes as he felt the warm liquid hitting his nose and cheeks, splashing everywhere.

 

“Open up, whore,” Snape said and Harry, unable to resist, obliged.

 

Severus aimed his stream into the boy's open mouth and watched as it filled with his urine. The pee overfilled and spilled down his chin and onto his chest.

 

“Swallow it.”

 

Harry swallowed and opened his mouth again, ready to collect more warm piss.

 

“Piss whore. Come whore. Dirty, filthy, slutty whore,” Snape chanted as he made Harry swallow his urine again and again.

 

When he was finished he made Harry lick his cock and balls clean. He then tucked himself away and took in the piss soaked boy in front of him, nipples still clamped and purpling.

 

“What do you say, Harry?”

 

“Thank you for letting me suck your cock and drink your piss, sir.”

 

“Are you ready for your third punishment?”

 

Harry looked up at him and, without hesitation, answered.

 

“Yes, sir.”

 

Severus stood Harry up and turned him around, sticking him to the St Andrew's cross so his backside was on display.

 

Severus conjured a thin wooden cane and moved around the cross to show it to Harry, whose eyes widened in fear and arousal.

 

“You will count and thank me.”

 

“How-”

 

Harry stopped himself and looked down, remembering he wasn't allowed to ask questions. 

 

“You may ask.”

 

Harry looked up at Severus again and took a breath.

 

“How many hits?” he whispered.

 

Snape smirked. 

 

“Until I'm satisfied.”

 

Harry gulped in fear and shut his eyes, nodding.

 

Severus walked back round so he could see Harry’s bare arse. He reached out a hand and caressed the boy’s bum cheeks, landing a few light spanks with his hand that caused Harry to jump and gasp in anticipation.

 

Eventually Severus stood and, without preamble, stuck Harry across the centre of his butt cheeks.

 

SMACK 

 

Harry gasped and whimpered in pain. Severus could see a red welt forming already on the white canvas. 

 

“One, thank you for punishing me Professor.”

 

SMACK

 

“Two, thank you for punishing me Professor.”

 

SMACK 

 

“Three, thank you for punishing me Professor.”

 

On and on it went, Severus raining down smacks to Harry’s arse as it quickly turned bright red. The boy’s gasps soon turned to sobs as he began crying in earnest. The thinness of the cane made each hit sting so much more than a spank. Severus enjoyed making some hits lighter and other harder, so the boy could never anticipate what would be next.

 

SMACK

 

SMACK

 

SMACK

 

SMACK

 

SMACK

 

SMACK

 

“Please, sir, please…” Harry whimpered, unaware he was talking let alone pleading. “I can't…please...I…”

 

Severus continued to bruise Harry's arse, delighting in the thick purple raised welts that came up. He continued and continued until the boy’s whole arse and upper thighs was a deep bruised purple and the boy was sobbing uncontrollably.

 

Severus moved closer and pressed his front against Harry’s back, causing a gasp from Harry as his burning arse was pressed against Severus’s clothed crotch.

 

Severus wrapped and arm around Harry’s chest and pressed kisses to the crook of Harry’s neck.

 

“You've done so well, my little boy, so well,” he soothed. “What a good little boy you are.”

 

Harry sobbed harder at the kind words but leant his head back again Severus’s chest, relishing the comfort.

 

“My good little boy, do you think you can take more?”

 

Harry turned his face, already past his limit of pain. He gasped and shuddered and Severus just left the question in the air, rubbing up and down Harry’s ribs, kissing his neck. 

 

Harry so desperately wanted to please this man. 

 

“Yes, sir,” he said, so quietly Severus would have missed it if he weren't as close to the boy as physically possible.

 

“Such a good boy,” Severus said again.

 

He took a step back and raised the cane, putting in his full strength.

 

SMACK

 

A line of blood slowly appeared as the cane broke the skin on Harry’s teenage bum cheeks. Harry sobbed loudly.

 

SMACK

 

A second line. The sobs grew

 

SMACK

 

A third. 

 

SMACK 

 

A fourth.

 

SMACK

 

Harry screamed.

 

Blood dripped down to his thighs.

 

“Well done, Harry,” Severus said, coming to hug him from behind again. “Well done, little boy.”

 

Severus took his wand and healed the broken skin until it appeared like it had never broken in the first place. He unstuck Harry from the cross and turned him round. Keeping one arm around his waist to hold him up, Severus pulled off the nipple clamps.

 

Harry spasmed at the sudden shooting pain as his nipples filled again with blood. He couldn't hold his own weight so Severus lifted him up and carried him to the leather sofa, laying him down gently. Harry hissed as his bum made contact with the sofa, but Severus cast a cooling charm on the leather to provide some relief 

 

Severus summoned the healing ointment and began applying it liberally to Harry’s nipples. He could see the purpling turning back to red and the swelling going down. He carefully wiped off the remaining ointment so that Harry would still have some pain in his nipples, a reminder of his punishment. 

 

Severus then helped turn the boy onto his front and applied ointment to his arse. Harry moaned as the welts reduced. Again Severus wiped off the ointment to stop the healing process going too far. He left the boy’s arse with multiple dark red lines covering the surface. That would be sufficient for the boy to feel every time he sat down in the coming days.

 

As Severus screwed the lid back on the jar, he heard Harry continuing to moan. He looked up and saw the boy had spread his legs wide and was sticking his arse up in the air.

 

“Do you want something, Harry?” Snape asked amused.

 

“Please, sir,” the boy whimpered.

 

“Please what?”

 

“Please put your fingers in my hole again,” he said as he pushed his arse up further, his tiny pink pucker displayed to Severus. 

 

Severus stifled a groan at the slutty boy before him. He forced himself to hold back. Today was about punishments not rewards.

 

“No, Harry, not today,” he said, not unkindly.

 

The boy’s cheeks flushed bright red from the embarrassment of being rejected by his professor.

 

Severus pulled the boy up to sitting and sat down next to him, pulling Harry into his lap and wrapping his arms around him. Harry quickly nestled his face into the crook of Severus's neck and held onto his muscular shoulders.

 

“You’re such a little slut, Harry, that your hole isn't punishment for you any longer,” Severus said quietly, kissing the top of the boy’s head. “But if you're a very good boy, I'll play with it again, okay?”

 

Harry nodded. “Yes, sir.”

 

“Let’s get you cleaned up,” Severus said, as he vanished the St Andrew's cross and conjured the bathtub with shower again. 

 

Severus helped Harry into the tub and rinsed him down (with warm water this time) and then wrapped him in another fluffy towel and an even bigger hug. Severus just held him for a while until it became apparent the boy wanted to say something but wasn't sure if he was allowed.

 

“Yes, Harry? Do you have a question?”

 

Harry squirmed.

 

“Sir? Er, I haven't had a wee yet. I was just wondering, er-” he trailed off

 

“Oh, no, Harry, not tonight,” Severus said, still holding the boy close.

 

“Sir?” Harry said, confused.

 

“Twice a day is an indulgence. And besides, you've been doing well. We can move down to once a day for you to pass urine. So we’ll keep the sound and cage in place tonight and I'll remove it tomorrow morning.”

 

Harry was shocked. He currently needed a wee. Not desperately, but there would be no way he could last until the morning.

 

However, Harry knew Snape by now and he knew there was no way to talk him round.

 

“Yes, sir,” he acquiesced, once again accepting his fate.

Chapter Text

Harry had spent all of the day before desperate to pass urine. Snape was now only allowing him to pass urine once a day so he was rapidly becoming familiar with the sensation of a full bladder. He struggled to sit still and it hadn't gone unnoticed, although Ron and Hermione thought it was mostly due to his agitation at the upcoming third task, though none of them knew what this would involve yet.

 

Harry arrived for his second punishment session with Snape. As soon as the door was closed he stripped naked and assumed the ‘submissive pose’, as Snape called it. Harry was sitting back on his heels with his knees spread and his hands holding each elbow behind his back, and his eyes downcast. 

 

Severus looked at the boy before him - his tiny caged cocklet sitting on his small and mostly smooth balls, his nipples erect in the cold dungeon air. He was perfect.

 

Severus walked over to Harry and began caressing his cheek, making the boy look up at him with those big green trusting eyes. 

 

“Hello Harry,” Severus murmured. “Are you going to be a good little boy for me today?”

 

Harry nodded. “Yes, sir. I promise to be a good boy for you today.”

 

Harry was so earnest in his promise that Severus wanted to fuck him right on the living room floor. He refrained himself, however. He wanted Harry’s first time to be as a reward, not a punishment.

 

“What are your crimes today, Harry?”

 

Harry didn't even hesitate. Listing his crimes and undergoing punishment was becoming so normal for him he wasn't even questioning it anymore.

 

“I failed a History of Magic essay, sir, and I hexed Malfoy in the corridor.”

 

“You hexed Malfoy?’ Severus frowned. “Why don't I know about this?”

 

“Because no-one caught me. I'm not even sure Malfoy knows it was me.”

 

Harry looked up at Severus with such an open face. He could have easily got away with hexing Malfoy - clearly no one had known. But he chose to confess to Severus anyway. Just the perfect little submissive.

 

Severus bent down and kissed Harry forcefully, pushing his tongue into the teen’s mouth and biting his lip. Harry surrendered immediately, kissing back but letting Severus have full control. When Severus pulled back there was a line of spit stretching between their mouths and Harry was panting needily.

 

“Good boy,” Severus said, and patted Harry’s head like a dog. “This way.”

 

Severus walked towards their playroom and Harry followed, not forgetting to crawl on the hard stone floor on his hands and knees.

 

Inside the room the bathtub was back. Severus helped Harry into the tub but this time didn't stick his limbs down, instead trusting Harry to behave.

 

“You had a big lunch so we’ll start with an enema before we move on to your punishments.”

 

“Yes, sir,” Harry said, though Severus noted his deflation at having to have another enema. The boy would just have to get used to it, Severus thought. He had plans for that tight arsehole and he wanted the inside of it to be squeaky clean.

 

Severus squirted some lube on Harry’s arsehole and pushed one finger in fully to the knuckle. Harry gasped at the painful intrusion, but pushed back on the finger anyway, lowering his head onto his forearms to improve the angle. Whether consciously or subconsciously Severus wasn't sure.

 

Severus quickly added a second and Harry whimpered. It was probably too soon but the boy would have to learn. Severus scissored his fingers for only a few seconds before adding in a third. He could feel a lot more resistance now - the hole had barely been able to take two fingers - but Severus pushed through anyway. 

 

“Relax, Harry,” Severus said, trying not to let his impatience show.

 

“Sorry, sir,” Harry panted as he tried to force his arsehole to relax. The burning stretch was consuming all his thoughts but he tried desperately to loosen it. 

 

Severus found the boy’s prostate and began thrusting his fingers in and out the boy, hitting the mark every time. The boy soon started gasping and whimpering from pleasure, despite the pain.

 

Severus withdrew his fingers and inserted the familiar nozzle, letting the bag of water squeeze into Harry’s rectum and bowel.

 

Harry began squirming but no sound escaped him as he took the full litre of water inside him. 

 

“Clench,” Severus said, and Harry squeezed his arsehole shut as Severus removed the nozzle. 

 

Harry was alarmed when he felt the nozzle re-enter his hole.

 

“Sir!-” he said, before he remembered he wasn't allowed to ask questions.

 

“We’ll do two litres today, I think,” Severus said cruelly. 

 

Harry tried to regulate his breathing. He could do another litre. He had managed the first litre much better than he had the first time. 

 

The cramping ramped up as more water flowed into his belly and soon Harry was writhing in the bathtub and sobbing quietly into his forearms. He felt like he was being inflated from the inside and would soon explode.

 

Severus palmed his cock through his trousers as he watched the boy's suffering. He could see the boy’s belly swelling with water. It almost made him look pregnant. 

 

When the two litres had gone inside, Severus commanded Harry to clench again. He was surprised the boy heard him over the sounds of his sobbing and hiccuping.

 

“You've done so well, Harry, such a good little boy for me,” he said as he stroked Harry’s hair and leant down to kiss his temple. Harry sobbed harder. 

 

“Now, Harry, could you do something for me?” Severus asked. He waited a full minute for Harry to look up at him. “You can say no, but if you feel like you can, I would really like it if you held all this water inside you for as long as you can, and then further still.” 

 

Silent tears dropped down the boy’s face. Severus continued to cradle his jaw and kiss his cheek. He waited patiently.

 

Eventually Harry nodded. “Yes, sir, I can do that,” he said, and Severus wanted to break him apart.

 

He moved round to the boy’s arse and withdrew the nozzle, watching as Harry’s tight little pucker clenched as hard as possible to keep all the water in. Severus began caressing the boy’s bum and stroking his large protruding belly. He would occasionally press down on the belly and Harry would gasp as he struggled with the strain of keeping everything inside. 

 

“Just hold on as long as you can, little boy,” Severus soothed. 

 

He rubbed his hand over the boy’s bum and grabbed the globes of flesh. He let his finger trace over the boy’s tiny arsehole and watched it spasm as it clenched further. 

 

“Good boy, such a good boy,” Severus murmured. 

 

Luckily he took his hand away just in time because Harry’s willpower gave up just then and water was forcefully rejected from his rectum. It flowed and flowed into the tub and the boy sobbed and sobbed. 

 

“Hush, Harry,” Severus said, moving round to caress the boy’s face again. “I'm so proud of you. Well done, little boy.”

 

Severus leant down and kissed Harry again, this time on the mouth. Harry opened up immediately, desperate for the affection he was being offered after his ordeal. 

 

Once Harry’s bowels were empty, Severus rinsed him down and put three fingers into his hole again, feeling the muscle spasm around him and the soft walls inside Harry’s rectum.

 

“Do you want me to fill this hole up?” Severus asked.

 

“Yes, sir!” Harry gasped, desperate for his used hole to be fucked. “Please, sir, please!” He added, feeling as though he had waited far too long to feel his teacher’s cock inside him, where it should be.

 

Severus laughed cruelly and conjured an inflatable butt plug. He coated it in lube and pushed it into the boy's warm channel. Harry gasped as he felt the cool silicon slide inside him, once again disappointed that it wasn't his master’s cock.

 

His master? Since when had Harry been thinking of Snape as his master? He shuddered at the thought and then yelped as he felt the butt plug inexplicably grow inside him. He pushed back against it, subconsciously needing to be filled by even more - by whatever Snape would give him.

 

Severus inflated the plug until it was four inches long and two inches at its widest. He then spanked Harry’s bum cheeks a few times on each side just because he wanted to and enjoyed it when the white flesh turned pink.

 

He helped Harry out the bath and stood him next to the tub. He commanded Harry to hold his arms out while Severus towelled the boy dry, like a child. Only then did he point his wand at the cock cage and unlock it. 

 

Severus gently removed the cage from around Harry’s baby cocklet and then he pulled out the sound, delighted when Harry’s urethra remained just a little wider than it naturally should be.

 

He stood behind Harry as usual and grasped the cocklet in his fist, pointing it at the bathtub.

 

“Okay Harry, you can have a wee wee now,” Severus murmured in the boy’s ear.

 

Harry let go at once and Severus enjoyed watching the stream of warm piss hit the bathtub. Severus dipped his hand in it and felt the warm wetness. Then he conjured a small glass and caught some of the urine in it. He brought the glass up to Harry’s face, while Harry was still pissing, and the boy didn't hesitate in opening his mouth and letting Severus pour his own hot urine down his throat. In fact, the boy drank it like he had been dying of thirst. 

 

Severus managed to fill two more glasses that Harry drank without question before the stream stopped. 

 

“Right, Harry,” Severus said while wanking the boy off where they stood and enjoying feeling the tiny cocklet harden under his touch. “Are you ready for your punishments?”

 

Harry whimpered in arousal.

 

“Y-yes, sir.”

 

Severus vanished the bathtub and conjured a padded bench in its stead. He placed Harry on it, lying on his back. He took Harry’s hands and pulled them far above his head, casting a sticking charm so Harry would be able to move them. He allowed Harry’s legs to stretch out in front of him, transfiguring the bench so it ended at the boy’s feet. 

 

Severus then conjured a large tub of hot wax and some strips of cotton fabric. He looked down at Harry who looked up at him with a face full of trust that went straight to Severus’s groin.

 

“Your first punishment is to have the hair on your body removed so that you can be nice and smooth for me,” Severus said. 

 

Harry nodded. “Yes, sir. I want to be smooth for you, if that’s how you would like me.”

 

Severus looked again at the green eyes, which held no hint of sarcasm, just the desire to obey Severus in any way possible.

 

Severus grabbed a wooden stick and spread hot wax over Harry's shin. He applied a cotton strip and, looking Harry in the eye, the boy’s face full of calm and trust, he ripped the strip off the boy’s leg.

 

“Aargh!” Harry screamed as he felt the little hairs on his leg being pulled out. He looked at Severus as though he had been betrayed. 

 

“This is a punishment, Harry,” Severus said sternly. “You deserve this pain. You're a little misbehaving boy and you need to learn how to act like a grown up. So either take your punishment like a man or I can get a dummy to gag you.”

 

Harry looked ashamed. “No, sir,” he murmured. “I'll be good, I promise.”

 

Severus smirked and stroked Harry’s hair. Harry turned his face into the comforting touch. 

 

Harry remained silent as the remaining hair on his legs was forcibly removed, even the sensitive area at the upper inner thigh. Just as he thought it was coming to an end, he felt hot wax fall on his armpit.

 

Harry wasn't a hairy child. He only had a few sparse hairs dotted around, but evidently Snape wanted him completely hairless. He kept his eyes tightly shut as the wax was ripped from his armpit. The pain was much worse than the legs because it was a more sensitive area.

 

Once both armpits were done he felt wax again on his lower belly, between his belly button and his pubic area. Harry forced himself to stay silent by biting his lower lip as the hair was also ripped out from there.

 

But Harry couldn't contain his gasp when he felt the hot wax fall onto his nipple and areola. He was certain he didn't even have hair there. He opened his eyes and saw Snape grinning gleefully down at him. He watched as Snape covered the wax in another cotton strip. He cried out when it was torn from his body.

 

“Aaarrghh!” Harry cried as he sobbed and sobbed. “I'm sorry, sir, I'm sorry for making a sound,” Harry choked out. 

 

“It’s okay, Harry,” Severus soothed as he brushed his fingers through Harry’s hair. “You're doing very well, little boy. Just a bit longer now.”

 

Harry nodded and looked at Severus with big water filled eyes.

 

Severus poured wax on the other nipple and Harry maintained eye contact. He placed the cotton strip on.

 

“You can cry and scream and make as much sound as you want from now on, my sweet little boy,” Severus said as he continued to stroke Harry’s hair like a small child.

 

RIP

 

“Aaarrghh!” 

 

Severus loved the boy’s choked sobs. He let the boy try to soothe himself as he moved back down to Harry’s bottom half. He lifted the boy’s legs up until his knees were almost at his shoulders. Severus cast a sticking spell so each foot was stuck to its corresponding thigh, essentially held in a fixed flexion at the knee. He then placed a metal bar between the knees and cast another sticking charm, essentially keeping the legs stretched wide apart. Lastly, Severus tied some rope from the bar to the top of the bench, where Harry’s hands were held, forcing the boy's legs up as far as they could go and lifting his bum off the bench until only the boy’s shoulders and head remained in contact with the padded surface.

 

Severus then started dripping hot wax over the boy’s bum. Harry whimpered but said nothing. 

 

Six strips later and Harry’s bum cheeks were a bright red, like most of the skin on his body now. Severus had a clear view of the boy’s anus with it's rim stretched around the inflated butt plug.

 

Severus deflated the plug and yanked the plug out. Harry whimpered, whether due to the pain of its removal or due to the sadness of its loss, Severus didn't know.

 

Severus dropped hot wax directly into the boy’s cleft and spread it around, ensuring the boy’s arsehole was completely coated in burning hot wax.

 

Harry’s silent sobs started to ramp up as Severus placed a cotton strip on either side of the cleft and ripped the sparse hair out. 

 

Harry screamed.

 

Severus lost no time in stopping to give the boy a reprieve as he lay another cotton strip over the boy’s arsehole and ripped as fast as he could 

 

“AAARRGHH!! Aaarrghh!” Harry screamed. “Please, no! No! Please, sir! Please, it hurts! It hurts so much!” Harry was choking on his sobs.

 

Severus laid a hand over the boy’s arse and soothingly stroked up and down, dipping his hand to the fluttering abused arsehole. 

 

“It’s okay, Harry, you're doing so well. Such a good little boy for me.” 

 

Harry’s whimpers gradually reduced.

 

“Do you want to be a really good boy for me, Harry?” Severus said, his eyes glinting with cruelty. 

 

Harry looked up at his teacher, his master, the man he longed to be good for. He couldn't imagine denying this man anything. He nodded slowly.

 

“Yes, sir.”

 

“I'm going to take the hair off your testicles, Harry.”

 

Harry sucked in a breathe and felt his heart beating fast in his chest. It would be agony. He looked at the dark brown eyes in front of him, almost black. 

 

“Please rip out the hair from my balls, sir. They're yours to do whatever you want with.”

 

Severus almost came in his trousers. Harry was handing over complete control to him; Severus was barely having to take it from him. 

 

Severus dripped hot wax onto the boy’s little sack and watched as Harry gasped and squirmed at the painful burning to his scrotum. Severus applied a cotton strip.

 

RIP

 

Harry screamed.

 

RIP

 

Harry screamed louder.

 

RIP

 

RIP

 

RIP

 

RIP

 

RIP

 

Harry was sobbing and hyperventilating from pain. It felt like his balls were on fire and there was nothing he could do cover up or remove the painful stimulus. 

 

Eventually he realised the ripping had stopped and Severus was leaning over him, running his hands over his neck and into his hair.

 

“Good boy, such a good boy,” Severus murmured, leaning down to kiss Harry on every inch of his face.

 

It took Harry a surprisingly short amount of time for the sobbing to die down and be replaced with whimpering, in need of more touch from Severus. 

 

“Please, sir-”

 

Harry started but stopped.

 

“What is it Harry?” Severus asked as he kissed below the boy’s ear.

 

Harry hesitated, but then Severus withdrew and looked down at him.

 

“Please kiss me, sir,” Harry said, so quietly it might have gone unheard. 

 

Severus leaned down and captured the boy’s mouth,which yielded immediately to its master. Severus enjoyed the slide of the boy’s tongue against his own and even the damp tears that were still silently falling.

 

Severus broke away and reinserted the inflatable butt plug, watching Harry shiver in arousal as he inflated up to its previous size. He loved seeing the black base plugging up his boy’s hole. 

 

Severus removed the leg spreader and unstuck Harry’s legs from their charm, allowing him to lie back down onto the bench. Once he was lying flat he stuck the boy down.

 

“Onto your second punishment, Harry.”

 

“Yes, sir. Thank you for removing all my hair, sir. Thank you for punishing me today.”

 

Severus almost growled.

 

He knelt down beside Harry and began pinching the boy’s nipples. He pulled and flicked and twisted them until they had turned a deep red and Harry was making little gasping sounds of pain. Severus was surprised by how much pain the boy could already handle. 

 

Severus kept going for about ten minutes, although to Harry it felt like hours. The nipples soon bruised and became so sore that even when Severus lightly stroked one it caused Harry pain.

 

Harry soon became lost in his own head, aware of nothing but pain in his nipples and Severus's hand which was inflicting it.

 

Severus looked down and saw Harry’s tiny cocklet was impossibly hard and leaking precum over his stomach. Severus moved one hand down to the cocklet and began stroking it, making Harry’s eyes suddenly open as he keened in desire.

 

Just as Harry was about to come Severus let go and Harry whimpered as he was unable to crest over into the orgasm he so desperately needed. 

 

Severus conjured a thick sewing needle and Harry’s eyes widened as Severus showed it to him. Then suddenly he felt ice over his left nipple as Severus’s other hand ran an ice cube over the pert little bud. Harry gasped in pain.

 

Without bothering to explain to Harry, Severus pinched the nipple in his left hand and pulled it upwards, away from the boy’s chest. He then lined up the needle and pushed through slowly until it had pierced through the nipple and exited the other side.

 

Harry screamed. 

 

At first Severus thought it was the pain of his sensitive nipple being pierced with a needle but when he looked down he saw that Harry had come covering his lower abdomen and his bay cocklet was shrinking back to its flaccid state.

 

The boy had come untouched, from pain alone. Severus grabbed the base of his own cock through his trousers to stop himself coming. Harry was clearly far more of a painslut that Severus had anticipated. 

 

“I'm sorry, sir! I'm sorry- I didn't mean to- I-”

 

Harry was panicking about coming without permission, as he should. 

 

Severus bent down and kissed the boy on the mouth, tangling his hands in the boy’s messy black hair.

 

“No,” Severus said. “You should not have come without permission. But otherwise you've been very good today, Harry. So we'll deal with that transgression next time, okay?”

 

“Yes, sir,” Harry mumbled. “I really am sorry,” he added, miserable that he had failed his master.

 

Severus lost no time in grabbing the right nipple. Harry noticed he wasn't using ice to numb it first this time, and he agreed that he didn't deserve such kindness.

 

Severus pulled the nipple far away and then stabbed through with a second needle. Harry forced himself to stay silent, accepting the pain as punishment, even though it made his baby cocklet twitch.

 

Severus then conjured two little metal rings. He opened some sort of clasp and then threaded it through one nipple as he removed the needle, reclasping it in place once the needle was out. Once both were done Harry looked down and saw his two nipples now shining with their metal adornments. 

 

“It'll be much easier to add weights to these,” Severus said, almost to himself, as he stroked his handiwork. 

 

Harry shuddered at the moment of the nipple weights. Still, he thought, it was nothing he didn't deserve.

 

“Okay, Harry, for your third punishment you can choose,” Severus said,towering over the boy. “You can either suck my cock again or I can torture your balls.”

 

It was a no-brainer really. Who would choose ball torture when they could suck Snape’s magnificent cock? Harry’s mouth started watering at the thought of having that monstrous thing inside his mouth and throat again. He wanted nothing more than to taste his master and milk him dry.

 

But Harry felt a pang of guilt. He had come without permission. He didn't deserve to suck his master’s cock, no matter how much he wanted to. Harry knew his master would love torturing his balls. He loved abusing them every chance he got. Harry was sure his master would prefer the second option.

 

Sighing heavily, Harry looked up at Severus and gathered his courage.

 

“Please could your torture my balls, sir? I want you to torture my balls.”

 

Severus was overjoyed.

 

He conjured a belt and wrapped it round Harry’s waist and then tucked his baby cocklet underneath it, to keep it out the way.

 

Severus summoned a flogger and wasted no time in laying light hits to Harry’s balls. Each hit made the boy whimper as his balls grew steadily more swollen and red.

 

And, to Severus’s disbelief, he then saw Harry’s little cocklet harden again under his ministrations. The boy was loving having his balls flogged. That wouldn't do, thought Severus.

 

He changed out the flogger for a riding crop and began hitting harder.

 

SLAP

 

SLAP

Severus hit the balls harder and harder until Harry was writhing in pain and his cocklet had gone flaccid again. Severus could see welts appearing over the smooth, now hairless, flesh as he continued the beating. 

 

SLAP

 

SLAP

 

SLAP

 

SLAP

The boy’s testicles looked swollen and bruised. Harry was sobbing again, choking on his cries as he lay bound and helpless to stop the agony hitting his most sensitive organ.

 

“I bet you love this, don't you, Harry?” Severus jeered, too far gone in his abuse. “You love having your manhood beaten up. Bet you'll come from just this one day like the painslut you are. Is it because it's your balls? Do you like having your balls hit? Does it make you feel like everything will return to how it should be if I can hurt your balls so much that they eventually just drop off?

 

“Do you want me to beat them up so bad they have to be removed? It's not like they can be used for anything, really, same as your baby cocklet. You're not a real man, so why have them? I could just beat them off you and then you can just go round with your arsehole alone. That's what you should be. Just a mouth hole and an arse hole, needing to be filled by real men with real cocks.”

 

Severus hit the balls with his full force and Harry screamed.

 

Severus put down the riding crop and conjured a small metal pinroller with metal spikes protruding. He grabbed Harry’s hot and purpling balls in his left hand as he ran the roller over them with his right.

 

Harry screamed again as he felt the sharp spikes stabbing into his overly sensitive balls. 

 

Severus didn't stop and continued running the roller over every inch of flesh, leaving little tracks of in its wake where the sharp spikes had dug into the abused skin.

 

Harry wasn't aware when the torture stopped. He only became aware that he was suddenly unbound and sitting in Snape’s lap on the leather sofa, with Snape running his hands up and down Harry’s back and soothing him with shushes and telling him he’d been a good boy.

 

Harry pressed his face into Snape’s neck and continued sobbing. His arms moved around to hold his professor’s chest as he tried to sink deeper into his offered body heat and comfort.

 

After a few minutes Harry’s crying eased up, although he still felt dull pain throbbing through his balls, as well as in both his nipples. 

 

“Well done, little boy, you've been so good for me,” Severus said, continuing to stroke the boy soothingly. “How do you feel, Harry?”

 

Harry hiccuped as he thought about it. 

 

“I-I f-feel,” Harry said as he looked up at Severus. “I still feel pain but mostly I just feel empty. And relaxed. And…safe.”

 

“Of course you do, Harry,” Severus said, cradling the boy even closer. “You're always safe with me. Pain is not the same as danger. You, Harry, clearly need a lot of pain in order to learn. For you pain is good. Does it feel good?”

 

Harry nodded. “Yes, sir. I didn't expect it, but the pain does feel good. Especially now when I can feel it but it's not as intense.”

 

“Good boy. Would you like a reward?”

 

“A reward?” Harry said, perking up at the suggestion and thinking about Snape sinking his massive cock into Harry’s arsehole. 

 

“Yes, I think you deserve one.”

 

“Yes, sir. I would love a reward, if you think it's deserved.”

 

Severus lay Harry down lying flat on the sofa. Harry watched as he conjured what appeared to be a child’s nappy, except it was bigger, almost like it was sized for an older child.

 

“I'm going to reward you, Harry, by not caging your baby cocklet up, not putting the sound in. I trust you not to touch yourself or pass urine without my permission. This,” he indicated to the nappy, “is just in case you can't control yourself. It's a safety net, that's all.”

 

Harry was alarmed at the prospect of wearing a nappy, especially if Snape wanted him to wear it to class. But he felt too overcome with the emotions and activities of the evening to protest. Plus, Snape was his master and he was helping Harry with his behaviour problem. He obviously knew best.

 

Harry nodded. “Okay, sir.”

 

Severus indicated for Harry to lift his hips, which he did willingly. Severus slipped the nappy underneath the boy’s bum and pulled out the side and down downwards. As he went to pull it up over the boy’s cocklet and balls, he checked to make sure the butt plug was still in place. He tapped it a few times and Harry jolted as it pressed into his prostate.

 

Severus did the nappy up and spelled it shut for added security. Then he pulled Harry back into his lap and continued hugging and caressing the boy.

 

The nappy felt strange around Harry’s groin. It was softer than expected, though it was large and he wasn't sure if it would be obvious under his trousers. He couldn't help himself sighing, however, when Snape patted his bottom like a baby. It was comforting and Harry leaned against Snape’s chest, shutting his eyes and giving into the comfort of his master’s body.

Chapter Text

“What do you think the next Task will be, Harry?”

 

Harry looked up from his breakfast to find both Ron and Hermione waiting for his answer.

 

“Er,” Harry said, his mind not remotely on the Tournament. “I don't know. What do you think it might be?” he said, hastily trying to distract his friends. 

 

Luckily Ron launched into a detailed explanation of what he envisioned for the final task and Harry was once again allowed to mostly answer in hums and nods. 

 

Harry was mostly focused on the odd sensations of his body. He could feel his nipples constantly; the new piercings still throbbed lightly and kept his nipples erect. Unfortunately that meant they brushed against his shirt easily. He had spent a considerable amount of time last night touching his nipples and gently twisting the piercings. He had quickly found that he loved any sensation on his nipples, which was part of the problem today.

 

Harry was sitting at the Gryffindor table and was forcing himself to not touch his own nipples. It took a considerable amount of restraint given Snape had never forbidden it, and therefore he was technically “allowed”. Harry silently cursed the social propriety that would object to him fondling his own titties in public. At breakfast no less.

 

Harry had also been concerned that the metal piercings would show beneath his school shirt. The last thing he wanted was for someone to notice his new jewellery; they might start asking questions. And while Harry was always ready with his “detentions for poor behaviour” excuse, a small (and probably honest) part of him had an inkling that, if anyone found out about these sessions, they would stop. And even though they were painful and humiliating and confusing, Harry knew without a shadow of a doubt that he did not want the sessions to stop.

 

He had decided to wear a plain white t-shirt underneath his school shirt today and it seemed to be working well. At least Ron and Hermione hadn't pointed out anything odd about his nipples, and they had been sitting opposite him all breakfast.

 

Harry was also acutely aware of the freedom of his penis. It had only been a couple of weeks but he was now used to the sound inside his urethra and the metal caging his baby cocklet. It was strange, but without them he felt…vulnerable. The sound had plugged him up and made him somehow feel full and the cage had felt his own little shield, though he would never have admitted it before. But now they were both gone and he felt oddly empty and exposed. 

 

The nicest part was the softness of the nappy he was wearing. Harry had been opposed to the idea of wearing a nappy - he was not a child, no matter what Snape implied - and the thought of it had been humiliating. It hadn't taken long for him to feel the comfort of the soft cotton against his newly hairless arse and balls. Where the loss of the cock cage made him uneasy, the nappy somehow now made him feel comfort and safety. And it wasn’t just due to the safety net of knowing he wouldn't have an accident in class. Instead it was almost like the safety of childhood, something Harry had never experienced. 

 

Harry downed the rest of his pumpkin juice and left the hall with Ron and Hermione for Transfiguration. Harry felt the slide of the soft nappy against his baby cocklet and balls as he walked and had to restrain himself from getting hard, which was much more difficult without the cock cage. Had he always been aroused this easily? Try as he might, he struggled to recall a time before Snape’s punishments.

 

In class he took the seat next to Ron, so he could be separated from Hermione. He knew he’d have difficulty focusing today and the last thing he needed was for Hermione to notice. 

 

As he sat on the wooden chair he let out a small gasp, which he covered by turning it into a cough. He had sat down too forcefully and the giant butt plug had impaled him further. It was the large inflatable plug Snape had used the night before, and Harry had grown to like it very much. Sometimes it would hit a very specific spot and he would have a jolt of pleasure. It had caused him to have an erection for half the night, but he had dutifully not touched his tiny cocklet. He hadn't even rutted against the bed, knowing that Snape would view any cause of ejaculation to be an act of disobedience. And Harry was desperately trying to be good for him.

 

Harry spent the whole lesson focused, not on turning the vase into a candle, but on the rival sensations in his nipples, cocklet, and arsehole. By the time the lesson ended Harry was desperate for the day to be over so he could see Snape and hopefully get some satisfaction from these warring sensations. 

 

The next class was History of Magic, which did nothing to help Harry’s concentration. Luckily there were only two people to a desk in this class and Harry had managed to find a table by himself at the back of class. He spent most of the lesson rocking rhythmically and feeling the plug press against his prostate as his cocklet and balls rubbed against the soft cotton nappy that was rapidly becoming more comfortable than his old pants.

 

By break time Harry needed a wee. It was only a moderate sensation and he knew he would be able to push through it, but it gave him a good excuse to see Snape.

 

Harry left his friends with a poorly concealed excuse and made his way to the dungeons. He hovered in the doorway as Snape’s seventh year class filed out the room. Snape was busy clearing up and didn't notice Harry, so he knocked on the door and stood with his arms behind his back (hand holding each elbow as Snape preferred) and his eyes downcast. 

 

“Ah, Mr Potter,” Snape said, and Harry felt a wave of disappointment at his reversion to Harry’s surname. Harry had grown very used to being called ‘Harry’ or even ‘good boy'; it made him feel like he and Snape had a special relationship, and like he meant something to the professor.

 

Harry remained in his modified submissive pose as his words caught in his throat. Perhaps coming here had been a mistake, he thought, if Snape was being so formal and distant. 

 

Severus had a moment of worry at seeing Harry stand in his doorway without moving or talking. He wondered if he had pushed the boy too far with the waxing and the piercings and the butt plug and the nappy. Perhaps it was too much for the boy and he wanted to bow out of their arrangement. Severus felt a pang of disappointment. He had become so used to having Harry as his little plaything, a toy he was molding, and he didn't want to give him up. He had quickly grown obsessed with the boy and simultaneously wanted to make him happy and break him apart.

 

“Close the door and come in,” Severus commanded softly.

 

Harry obeyed instantly and Severus threw up the privacy and locking charms wordlessly.

 

“Are you okay, Harry?” Severus asked as Harry took a few paces into the room. He was genuinely concerned and forgot to add any curtness to his voice.

 

Harry felt a sudden lump in his throat at the use of his first name, and the softness in Severus's tone. He felt a sudden rush of being cared for, and it was suddenly one sensation too many. Harry fought the sudden need to cry as tears started to well up in his eyes. In that moment he wanted comfort and safety and so he did the only thing that was instinctive. He fell to his knees and began to crawl along the cold stone dungeon floor towards his professor. 

 

Once Severus’s shoes came into his vision he stopped and knelt at his teacher’s feet, arms behind his back and head looking down at the black shiny shoes. 

 

Severus responded slowly, unsure what the boy needed. He threaded his fingers through Harry’s wild black hair and felt the boy push into the touch. 

 

“What do you need, Harry?”

 

Harry couldn't speak and he honestly didn't know what he needed. After a few seconds he leant forward and pressed his forehead against Severus's thigh, wanting to be close to the man, and enjoying the repetitive stroking of his hair. 

 

He leaned in further and turned his head, which was now eye level with his professor’s large cock. He moved forwards and began nuzzling at the massive clothed penis, seeking comfort in its warmth. 

 

Suddenly Harry knew he needed nothing more than Snape’s monstrous cock. He wanted Snape to thrust it into his mouth and down his throat. He wanted it repeatedly rammed into him until he gagged and couldn't breathe. He wanted to be pushed to the point where he wouldn't be able to think of anything at all, except his master’s perfect cock. 

 

“Easy, boy,” Severus murmured, and he gently pulled Harry’s hair back so he was no longer able to mouth at his professor's cock. 

 

Harry looked up at Severus for the first time since he had arrived at the potions classroom. He looked almost lost and pleading at having been removed from the comforting cock. When Severus let go of his hair and took a step away he whimpered like an abandoned dog.

 

Severus immediately stroked Harry’s cheek instead.

 

“It’s okay, little boy,” he soothed. “I'm just going to sit in my chair so we can be more comfortable.” He could see Harry’s watery eyes as the boy forced back his tears. “You are going to crawl after me, okay?”

 

Harry nodded and Severus didn't push him to speak. Clearly the boy needed to remain voiceless at present. 

 

Severus walked around his desk and sat in the large straight-backed leather desk chair, Harry dutifully crawling along barely a pace behind. Severus settled the boy between his legs and Harry immediately resumed nuzzling his monster cock.

 

Severus threaded both hands through Harry’s hair and stroked the boy while holding him close. 

 

“Are you going to tell me what’s wrong, Harry?” 

 

Harry shook his head and continued nuzzling, inhaling the scent of his master and feeling the man’s cock harden under his ministrations. 

 

“I need to know what’s wrong so I can help you, little boy.”

 

Harry pressed his cheek to the cock and felt the hard member along the length of his face.

 

“Harry,” Severus said warningly as he pulled Harry’s head back so he could look the teenager in the eye.

 

Harry initially tried to look away but Severus wouldn't let him. After a few minutes Harry seemed calmer and the watery eyes had disappeared. Severus held the boy’s jaw and stroked his thumb along the boy’s cheek. Harry sighed in contentment.

 

“I need you to answer me, Harry,” Severus whispered. “Why don't we start with something easier? What made you come to see me just now?”

 

Harry shifted slightly but felt more able to speak. 

 

“I, er, needed a wee.”

 

“Good boy,” Severus said and he watched Harry’s face light up at the praise. “Thank you for telling me, Harry.”

 

Harry’s cheeks flushed red in embarrassment but he looked so happy to be doing well.

 

“And what caused this little wobbly episode just now?”

 

Harry looked away but Severus pulled his face back up so they were once again locked in eye contact. Severus maintained the silence and knew he could not be the first to break it. Eventually Harry spoke with a trembling whisper.

 

“You called me ‘Mr Potter’,” Harry said finally and this time he looked away and refused to look back at Severus despite the professor’s attempts. Severus could tell this admission cost the boy a lot.

 

“Thank you for telling me, Harry,” Severus said as he absently stroked through Harry’s hair again. Harry closed his eyes at the sensation. “You're such a good boy, Harry. You're doing so well for me.”

 

Harry’s cheeks flushed again in embarrassment, though it was obvious the boy loved the praise.

 

“Harry, do you not like it when I call you by your surname?”

 

Harry shook his head.

 

“Why, Harry?”

 

Severus waited again, continuing his gentle caresses.

 

“It’s impersonal,” Harry eventually said simply, though Severus was able to read between the lines.

 

“What do you like me calling you?” Severus asked.

 

Harry shrugged. 

 

“Do you like it when I call you ‘Harry’?”

 

Harry looked up at Severus again and nodded.

 

“Okay, that's good. Well done for telling me, Harry.”

 

Harry smiled a small smile.

 

“I might have to call you ‘Potter’ in class though, otherwise everyone will be very confused,” Severus warned. “Is that okay?” he asked.

 

“Yes,” Harry said at length. “But can you call me ‘Harry’ if it's just the two of us? Even if it's in the main castle?”

 

Severus looked at the boy’s hopeful eyes and he was helpless to deny him anything. 

 

“Of course,” he said. “As long as it's just the two of us alone, I won't refer to you by your surname.”

 

Harry grinned widely.

 

“Unless you've been a very bad boy and are in need of punishment,” Severus added coldly. 

 

Harry’s grin turned sly and he nodded. “Yes, sir.”

 

“If that’s all, we should-”

 

Severus stopped as Harry made to open his mouth and then closed it. 

 

“What?” he asked of the boy.

 

Harry shook his head.

 

“Tell me now, Harry,” Severus said in his threatening voice.

 

“I-,” Harry said, clearly building up the courage. “I like it when you call me ‘good boy’ or ‘little boy’ and I don't want you to stop,” he said very quickly and all in one breath.

 

Severus almost growled. Instead he reached forward and cupped Harry’s jaw and then leant down and kissed the boy roughly. Harry opened up immediately and let his professor’s tongue enter his mouth and suck and bite on his bottom lip. The kiss deepened and Harry let out little mewls and whines as his teacher snogged him as he knelt between the man’s legs.

 

When they broke apart Harry was breathless and his baby cocklet was hard as a rock. Luckily it's tiny size and the padding of the nappy meant it wasn't visible at all.

 

Severus's smile was predatory as he looked down at the needy boy in front of him.

 

“Good little boy.”

 

Harry whimpered.

 

“You're my good little boy.”

 

Harry bit his lip.

 

“Say it.”

 

Harry looked excellent, his lips red and swollen from kissing, his face pointed down but his green eyes looking at Severus through long dark eyelashes. 

 

“I'm your good little boy, sir.”

 

Severus kissed him again, softly this time.

 

“Do you need to pass urine, Harry?” Severus asked.

 

Harry bit his lip again. He wanted to be a good boy for his master.

 

“I- I think I can hold it, sir.”

 

“Good good,” Severus said. “I want you to hold your bladder for as long as you can today, okay?”

 

Harry nodded. “Yes, sir.”

 

“You can go now.”

 

Harry hesitated, still on his knees between his teacher's spread thighs, looking at the man’s giant cock tenting his trousers. 

 

“What is it, Harry?” Severus asked commandingly.

 

“I, er,” Harry said, building up the courage. 

 

Severus tutted, which prompted Harry to answer quicker.

 

“Please, sir, please can I suck your cock?”

 

God, the boy asked so nicely and Severus was so hard. But he was training Harry and that would have to take priority.

 

“No, Harry.”

 

Harry looked devastated. He had clearly not expected to be denied his request, especially as it was about satisfying Severus and hot himself.

 

Harry fought back another sudden rush of wanting to cry. He took a few deep breaths through his nose. Severus had been comforting him for the last quarter of an hour and he had been lulled into thinking it could continue. Harry had found it so calming, so grounding, to mouth against his master’s cock earlier and he was still desperate to lose himself in having his face fucked until he was unable to think of anything else.

 

“Why do you want to suck my cock, Harry?” Severus asked gently, as he moved to stroke Harry’s hair again. 

 

Harry couldn't bring himself to tell Snape. Not after he was just rejected by the man.

 

Instead he shrugged. “I don't know, sir.”

 

Harry was glad the words came out neutrally despite the strange overwhelming emotions he was feeling.

 

“Do you want to know what I think?” Severus said, continuing to stroke the boy and ignoring the feeling of guilt in his chest as he looked at the boy who looked as though he was a puppy who had just been kicked. “I think you want to suck my cock because when you suck it you can properly let go. I think it makes you feel everything and nothing.” 

 

Harry said nothing.

 

“I want you to find other ways to let go, Harry. To give in. To release all that pent up energy and repression you've stored up.”

 

Harry looked up at him again. “What other ways?”

 

“I want you to use the nappy, Harry.”

 

Harry gasped and shook his head. “No, I can't, sir, please-”

 

“Hush, boy,” Severus soothed. “It's not a punishment, it's a reward.”

 

Harry looked very doubtful.

 

“I want nothing but good things for you Harry. Do you trust me?”

 

Cautiously, Harry nodded. He had never felt safe until he had started being punished by Snape, despite the pain and fear involved. Snape had always taken good care of him so far, and only hurt him for his own benefit, so he could learn how to be good and behave properly.

 

“Then I don't want you to come to see me again until your nappy is wet with your little boy urine. When it’s wet you will come see me and I’ll get you cleaned up and changed.”

 

Though he was very unsure about this, Harry nodded. “Yes, sir.”

 


 

Severus had given Harry a tonic for ‘nerves’ as he left the potions classroom, and Severus smiled to himself now while eating lunch in the Great Hall. The tonic had actually been a potent diuretic and he was very much looking forward to Harry wetting his nappy in public (not that anyone would know) and then coming to see Severus for a nappy change.

 

Severus watched the boy at the Gryffindor table drinking his pumpkin juice and unaware of what the next hour or so would entail.

 


 

Harry was in Herbology when his bladder started to feel uncomfortably full. By now he had thought he was good at holding his bladder but perhaps the sound had helped a lot more than he thought. 

 

He could barely listen to Professor Sprout’s explanation and when he was passed his dancing sunflower he could only grimace at Neville. 

 

Luckily the class was an active one as usual so no one paid him any attention as he sat pretending to move around soil rather than repotting his sunflower as he was supposed to. In fact he was doing such a terrible job of looking after his sunflower that he briefly wondered if he'd been given a Muggle one as it hasn't moved at all, while Neville’s was somehow now dancing what appeared to be the macarena.

 

Harry grasped the sunflower pot between his hands as he tensed his abdomen and pelvic floor with the effort of keeping his urine in.

 

He was not going to wet himself in the middle of class, in front of all his friends and the Hufflepuffs. Fuck Snape, he thought. He didn't need to learn to let go, he just needed to exert more control. He could will himself to stay dry.

 

The idea of excusing himself for the bathroom never even occurred to him. Perhaps it was because it had been so long since he had been allowed to use a toilet. Though Harry knew it was really that he was battling Snape’s instructions. 

 

He looked at the clock. Twenty minutes to go.

 

Just hold on.

 

Fifteen minutes to go.

 

A little bit more.

 

Twelve minutes to go.

 

Come on.

 

At eleven minutes to go he felt a spurt of urine from the end of his baby cocklet and the accompanying warmth in his nappy, and he knew it was over.

 

Harry let go.

 

He felt as the urine poured out from his penis forcefully and he felt nothing except immense satisfaction and contentment at the feeling of release.

 

He could also feel the warm wetness of the soft cotton of the nappy surrounding him. He could feel his baby cocklet and testicles against the damp cloth and could even feel it running behind him until it felt like he was sitting on a soaking wet towel. He could almost convince himself that if he moved his weight from one arse cheek to the other he could hear a squelch.

 

To his surprise Harry liked the feeling of the wet nappy. It was different to when it was dry but it wasn’t unpleasant.

 

Harry’s urine flow continued and continued and, now the initial shock was over, he was able to look around the room and his classmates. 

 

He felt a jolt of adrenaline and arousal at the feeling of pissing his pants right in the middle of class. It felt wrong and dirty, but it also felt freeing and Harry let out a small laugh. 

 

Neville turned to him with a smile, presumably thinking he was enjoying the dancing sunflowers as much as Neville was. Harry smiled back and for the brief moment they made eye contact Harry enjoyed feeling the urine leave his baby cocklet. He felt his own joy at the thought Neville would never know that, in that moment, Harry was pissing into an enlarged nappy.

 

Harry then made an effort to see how many people he could make eye contact with while the last jets of urine poured into the nappy. He had quickly realised this nappy had clearly been spelled to hold huge volumes of water without spilling as he was pretty sure he had pissed close to a litre of urine.

 

When the stream finally finished Harry could feel his soaking wet nappy weighing him down and sagging around his groin. He was completely unsurprised that his baby cocklet was now rock solid. He had been in an almost permanent state of arousal all day.

 

Knowing Snape wouldn't be free during class, and also wanting to feel the wet nappy as it cooled down, Harry re-engaged with the lesson and joined in the general chatter of his friends.

 

After Herbology they had Charms and Harry walked with his friends to the castle, feeling the cold dampness against his arse and cocklet and balls the whole way. Combined with the enormous butt plug still lodged in his arsehole he was so aroused he almost came during the walk.

 

When Charms finished Harry rushed to the Potions classroom, hoping to catch Snape before dinner. He wasn't sure how long the spell work would last on a side nappy and he didn't want to risk it.

 

Unfortunately he found Snape in the Entrance Hall about to enter the Great Hall for dinner.

 

“Er, professor!” Harry called.

 

Severus turned around and eyed the boy. 

 

“I was, er, wondering if I could talk to you about something, sir?” Harry said, trying to indicate with his eyes.

 

Severus gave a long suffering sigh and rolled his eyes. “Very well, then.”

 

Harry noticed Snape had avoided calling him ‘Potter’ and his stomach gave a little jolt as he followed behind his teacher.

 

Snape led him to his quarters rather than his classroom. Once inside with the door closed Snape raised an eyebrow and Harry stripped down until he was wearing only his soaking wet nappy. He knelt on the floor in the submissive pose.

 

“Ah, little boy, I see you’ve wet yourself.”

 

“Yes, sir.”

 

“How did it feel?”

 

Harry looked up at Severus and grinned. “I liked it, sir.”

 

Severus raised an eyebrow. “You liked pissing yourself in public like a little dirty boy while wearing a nappy like a baby?” Severus sneered.

 

Harry felt his cheeks flush in embarrassment. “Yes, sir.”

 

“Why is that?”

 

Harry maintained eye contact. “Because I'm a dirty little boy who can't control himself.”

 

“Yes, you are, aren't you?” Severus said while moving forward and yanking Harry’s head up by the hair. “But you're my dirty little boy, aren't you?”

 

Harry shuddered. “Yes, sir.”

 

Severus eyed the boy hungrily and then moved towards the sofa. With a flick of his wand he cleared the wooden coffee table and transfigured it to be slightly larger. He then transfigured the top to be a baby changing station.

 

“Climb up, little boy.”

 

Harry wasted no time in crawling to the new changing table and climbing onto it, lying on his back. He knew what was coming and he couldn't wait to be changed now that his whole attitude to nappies had shifted.

 

“Good boy,” Severus said once Harry was in position.

 

He leant over and undid the tape on either side of Harry’s hip and gently pulled down the sodden nappy. Severus felt a jolt of excitement at seeing Harry’s tiny erect cocklet sitting on his completely hairless balls. He reached out and fondled them, relishing the smoothness of the skin as well as the dampness from the leftover urine. 

 

Harry groaned as Severus lightly stroked his baby cocklet. The poor thing had been aroused for hours at this point. 

 

Severus eyed the thick wet cotton inside the nappy and brought his face down to sniff it. Unable to resist he also licked the cotton and then sucked up a small amount of his boy’s cold urine into his mouth. It was mostly clear due to the volume but it still tasted of Harry and Severus loved it.

 

Harry’s eyes were dilated as he watched the actions of his school teacher. He was desperately trying not to buck his hips as he willed Severus to touch him more. But Harry knew by now that demanding satisfaction would not work and so he forced himself to lie still and accept whatever offerings Severus gave him. Severus pushed his knees up and Harry dutifully held onto them, allowing Severus full access to his genitals and hole.

 

Severus reached down to the large black butt plug sitting in Harry’s arsehole. He muttered the spell to deflate it and yanked it out, causing Harry to shout out in pain as most of the lube had dried up.

 

Harry Potter’s once tight virginal hole was now gaping and trying to clench around thin air. Severus could see the puffy arsehole lips spasming and could even see inside the boy’s rectum to the internal red walls. 

 

Severus muttered a quick lubrication spell and thrust in three fingers as far as they would go, relishing in Harry’s gasp at being filled again. Severus could feel the softly smooth walls of Harry’s rectum and he quickly started pumping his fingers in and out at a rough pace. 

 

Harry was gasping and moaning by this point, eyes closed as he held himself open to Severus.

 

“Open your eyes, whore,” Severus hissed and Harry obeyed instantly. Severus added a fourth finger and relished in the teenager’s squirm of pain as his arsehole stretched wider.

 

“P-please, sir-” Harry begged.

 

“Please what?”

 

“P-please f-fuck me, sir,” Harry said. “P-p-please, sir. I n-need your cock, sir.”

 

“You need my cock?”

 

“Yes, s-s-sir,” Harry said, clearly verging on delirious at this point as his baby cocklet leaked a steady stream of precum over his pubic area.

 

“What part of you needs my cock?”

 

“M-my arsehole, s-sir,” Harry gasped.

 

“You mean your pathetic little boy cunt?”

 

Harry nodded, though Severus would have been surprised if he was wholly following the conversation while Severus was roughly finger fucking the boy and hitting his prostate every other thrust.

 

“Y-y-yes, s-sir. My p-pathetic little boy c-cunt needs your g-giant cock, s-sir. M-my hole is d-desperate for you.”

 

Severus was unable to resist any longer. It wasn't how he had planned to do it but the boy was actually begging to be fucked by him. It was better than Severus imagined. 

 

Severus yanked the boy forward until his arse was at the very end of the changing table, the wet nappy dangling off the end. He quickly undid his own trousers and pushed them down just far enough to release his cock, which was jutting out in front of him at twelve inches long and six inches in circumference. 

 

Severus grabbed the base and lined the thick blunt bellend up with the teenage boy’s hole. Despite four fingers and a full day with an inflatable butt plug the boy’s hole was still much smaller than Severus’s cock. He quickly conjured more lube and coated both his cock and the boy’s hole again.

 

Severus started to thrust slowly.

 

Harry began writhing as he felt his hole stretched impossibly wide. It burnt and stung all over again and he felt as though he was being ripped apart from the inside. He shut his eyes and tried to relax. He refused to tell Severus to stop. He wanted this desperately, he had been thinking of little else all day. He wanted his master’s cock buried deep inside him.

 

Severus continued pushing in through the tight ring, ignoring the whimpering of the boy he was impaling. 

 

He knew from experience that even adults struggled to take his whole cock and therefore the whole thing would be too much for Harry, at least for his first time. He stopped when he was halfway in and, not leaving time for Harry to adjust he pulled back out and then rammed straight back in, brutally rough.

 

Harry screamed as his professor took his virginity viciously. He felt nothing but pain as Severus withdrew again. But this time when he rammed back in Harry felt a sudden jolt of pleasure as Severus hit his prostate. And it was perfect. 

 

Harry loved the pain. He loved suffering for his master. He loved the happiness his agony caused Severus. And now he got to experience both the pain and the pleasure together and it was glorious. 

 

Harry’s eyes started to roll back as he felt the monster cock thrust in and out, in and out, in and out of his previously tiny anus. He felt so full, he wanted to keep the cock inside him and he started clenching his arsehole as tight as possible in order to draw it up even further. He would have laughed at Severus's groan if he was capable of doing anything except holding his knees up to his chest as his professor raped his little boy cunt.

 

“What do you say, boy?” Severus barked.

 

“Thank you for fucking my dirty boy cunt, master!” Harry gasped. “Please don't stop!”

 

Severus growled and started thrusting faster and harder, lodging slightly more of his giant cock inside the teenager each time, while Harry’s baby cocklet lay hard and leaking but neglected, as it should be.

 

Severus relished in the tightness of the once-virginal hole as squeezed his cock. He felt his massive balls tighten and then suddenly he was filling Harry with come as he boy milked his cock for every last drop.

 

Harry felt the spurt of warm liquid inside him and smiled as he realised he had managed to satisfy Severus’s need, which was quickly becoming one of the most important things in the world to Harry. He squeezed his arsehole shut in order to keep his professor’s come inside his body for as long as possible.

 

Severus pulled out his cock and immediately plugged the boy with four fingers, pushing in until most of his hand was inside the teenager, only stoppered by where Severus's thumb joins the rest of his hand.

 

Severus continued twisting and thrusting with his hand, making sure to hit Harry’s prostate each time until the boy was once again writhing at the edge of an orgasm that couldn't be achieved due to his neglected cocklet. 

 

Severus could see his own come leaking out the boy's loose and ruined hole and he watched as it drilled down his own wrist. With his other hand he grabbed his monster cock and aimed it at the baby cocklet, letting out a jet of urine. 

 

Severus pissed on the teenager in front of him, soaking his hard and aching purple baby cocklet as well as his silky smooth balls in hot urine. 

 

Harry’s eyes widened as he watched and felt his professor piss on him while continuing to fuck his boy cunt with half his hand, and it was exactly what he needed to push him over the edge as he spasmed out the most intense orgasm of his young life. His baby cocklet spurted hot white come over his abdomen as Harry arched his back. 

 

Severus couldn't believe the boy had orgasmed without his cocklet being touched at all. He growled as he continued pissing on the boy still spasming with aftershocks. He quickly removed the hand in the boy’s arsehole and instead aimed his cock at the hole and watched as he pissed directly into Harry’s rectum, his hole so gaping that the stream entered perfectly without hitting the rim.

 

Severus could tell Harry loved it by the way his arsehole began trying to clench around the stream. It didn't succeed and only found air. 

 

Severus looked at his boy lying on the table, eyes shut, panting, and positively glowing in the aftermath. He was sweaty and covered in piss and looked utterly delightful. Severus moved round to Harry’s side and slid one arm under his shoulder and the other under his legs and lifted the boy into his arms. He could feel his own urine and come dribbling out the boy’s ruined anus.

 

Harry barely acknowledged the lift, except to turn his head towards Severus’s arm and nuzzle in.

 

Severus carried Harry to the bathroom and placed him gently into the bathtub, before moving to turn on the taps. The bath filled quickly and Severus worked in silence to gently clean every inch on Harry’s body with a soapy cloth. Harry obeyed every intimated command as he allowed his master to take care of him. 

 

By the time he was clean and Severus was helping him out the bath he was able to stand on his feet, though he was slightly wobbly. Severus wrapped him in a giant fluffy towel and hugged the boy close to his chest, pressing kisses to the boy’s temple. 

 

“Are you okay, Harry?” Severus murmured into the boy’s hair.

 

“Yes, sir,” Harry said, sounding drowsy. “Never better.”

 

Severus smiled into Harry’s hair as he held him just slightly closer. 

 

It was still early and dinner in the Great Hall would likely not be finished for another fifteen minutes, but Severus was loathe to separate from Harry. Instead he brought the boy into the living room and sat them both in the sofa, with Harry between Severus's legs and his back leaning against Severus’s chest.

 

Harry rested his head on Severus's chest and was asleep within minutes, with Severus continuing to hold him and kiss him the whole time. 

 

An hour later Harry woke up but Severus continued to hold him close. When Harry felt able to sit independently, Severus summoned a house elf and had dinner brought up for both of them. They ate at the kitchen table in comfortable silence, Harry still naked and wrapped in the now-dry fluffy towel.

 

“I'll give you a choice today, Harry,” Severus said.

 

Harry just looked at his master and smiled.

 

“Would you prefer to have the sound and cock cage back or would you prefer another nappy?” 

 

“I want whatever you want me to have, sir.” 

 

Severus smiled at his boy. “Then you shall have the cage and the nappy.”

 

“Yes, sir,” Harry said. “Will I have the butt plug as well?”

 

Severus shook his head. “No, Harry, your boy cunt needs time to heal after tonight. I want it back to it’s original tightness by the next time I fuck you.”

 

“Yes, sir.”

 

Severus took his time putting on the cock cage and Harry’s new clean nappy, and then he helped dress the boy, briefly brushing over his pierced nipples and making Harry gasp.

 

As soon as Harry left for the Gryffindor dorm, Severus took out his pensieve and added the memory of him fucking Harry Potter to the mix.
