Severus shifted in his seat, sweat beading on his forehead as he took another deep breath, attempting to steady himself. He was uncomfortably warm all over, his clothes seemed stifling and itchy and it was all he could do not to rend his robes in two and fling them away from his overheated body.
His Alpha had forbidden him from wearing his regular plug today. Since there was nothing to stopper his continuously clenching hole, slick simply pooled in his pants, the viscous fluid running down his legs and soaking his trousers.
The burn of heat-induced arousal had started a few hours ago, coming on slowly, an ember that was -while not quite a raging inferno yet - sizzling within him as an impossible-to-ignore, hot-and-bothersome need.
Especially since his mate was right there, seated at a desk in Severus' classroom under the guise of detention, and ignoring him. Ostensibly doing some sort of homework. Or possibly writing up a list of new and creative ways to torture his poor omega. Severus couldn't see the content of the scrawl across the parchment from his own desk, but the latter was a great deal more likely, he decided sullenly.
Severus was suddenly overcome with the petty urge to knock a vial off his desk like a troublesome cat in order to gain Harry's attention. But his damned Alpha had already warned him that he'd earned a punishment tonight, and so he resisted the urge to make his circumstances any worse than they had to be. Severus had set Harry a detention under the Alpha's orders to last all week, an excuse to be together while the Hogwarts population at large was currently unaware of their mating. It was to last for the full week because it was Severus' heat. It was Severus' heat and therefore Harry was supposed to be seeing to that instead of letting his poor, neglected omega literally stew in his own juices.
Another wave of arousal hit him and he shifted as imperceptibly as humanly possible. Perhaps Harry wasn't paying attention; maybe if Severus very, very carefully and slowly slid his hand under his desk, he might be able to gain a modicum of relief…
His creeping hand stilled at the pointed cough, breaking the silence.
"I know my omega isn't disobeying something so simple as 'sit quiet and still at your desk until I tell you otherwise'", Harry's taunting voice sailed from halfway across the room.
Severus moved his hand back up to the tabletop with a huff, digging his nails into the grain. His noise of displeasure was met with a pointed look from his insufferable Alpha, but since it was more amused than angry, Severus felt comfortable enough to meet his gaze and try and make his displeasure more clearly known. He hadn't been long mated to Harry and though the Alpha wasn't nearly as cruel to him as he had the right to be, he'd made his ability to carry out punishments clear already.
Apparently Severus wasn't a very respectful omega.
Well, who could have been surprised about that! He'd never wanted to be an omega, never wanted anyone to know. Never expected to have an Alpha, let alone intended to ever learn how to submit to one.
He'd been on omega suppressants since puberty, and he'd successfully passed as a beta for his entire adult life. All until the unlucky day that his injuries had interfered with his carefully curated potions regimen and his heat had come, unexpected and unwanted, at the end of a class. As his luck would have it, he immediately attracted the green Alpha, leading to a frenzied mating in his potions cupboard of all places.
And then the boy had gone and claimed him, of all the idiotic things.
He had spent the last couple of months getting used to his new circumstances and even though he had to admit they were not as horrific as they could have been, it still burned him to remember such an undignified first meeting. And especially how easy, and how right it had felt. How he'd melted at Harry's strength, the way he held him down against the cold floor, fucked into him hard and fast, sating a deep need he never knew he had...he groaned at the memory, his prick hard as a diamond and soaking the front of his ruined pants with precome.
His Alpha looked up from his parchment at the noise, taking a quick breath at what must have been quite the expression on Severus' face. Harry must be on some kind of libido dampener in order to be so controlled in the presence of his aroused, mated Omega. Severus suddenly wanted to cry with frustration. Though the need wasn't unbearable yet, his Alpha's forethought meant he really was in for punishment, and the thought of a long night of being teased and denied the cock he so desperately wanted stretched out before him and he despaired. He tried another approach, an appeal to his Alpha's mercy, and put on his best attempt at a remorseful expression to replace the annoyed one.
Something flickered across Harry's expression at the change, but what precisely it was was difficult to tell even with Severus' experience reading his Alphas moods. His scent was difficult to parse out underneath the dampener, so it put Severus a bit at sea.
"You know you're being punished," Harry said calmly, his green eyes fixed on him with an intensity that made Severus shudder.
"Yes, and I sincerely apologize for my error, Alpha," Severus said dutifully and with at least a passing attempt at respect. It still rankled him to have to apologize to a student twenty years his junior, but it was more likely to appease the young man than trying to argue his way out if it. He'd tried that before, with nothing to show for it besides a deeply bruised bum.
If anything though, Harry just looked more amused. "What are you apologizing for, Omega?"
Severus bit his tongue and elected to not say that he was sorry he was forced to deal with miscreants and dunderheads all day, as that would surely earn him more punishment. "I was disrespectful to you and your peers in class. I was...unnecessarily cruel to your friends and I may have insinuated that you were, ah--" Severus searched his memory and flushed a bit. He was emotional in the days leading up to his heat and could not be held completely accountable for those actions, in his opinion. "--ah, neither intelligent nor deserving of admiration."
"Head stuffed with broom bristles, I think, was one of your more colorful insults," Harry replied. "Ego bigger than the quidditch pitch? Do you really think that of me?"
A tuft of anger was coming through in his tone towards the end of his response, and Severus admitted to himself that he did feel at least a little ashamed. Harry had been a better Alpha than he'd ever dreamed would be possible, and he didn't deserve his insults and disrespect. Especially, a small voice reminded him, since Severus was bound to his Alpha for life--but Harry could choose to dispose of him and find a better mate at any time.
"No, Alpha," Severus said quietly. "I do apologize. I was overly emotional and I didn't mean what I said."
Harry looked somewhat approving, though not entirely convinced. "I told you you'd be receiving a punishment tonight, and here's what it is. I will not be fucking you until tomorrow at the earliest."
Severus' eyes widened in shock. A full day of being in heat without mating?
"However, if you show me that you know how to be a good and obedient omega for me, tonight won't be as unenjoyable for you as it could be."
Severus swallowed. Harry was proving to be a...creative Alpha and he had no doubt already concocted several scenarios in his mind dependent on Severus' behavior. It behooved him to give a sincere attempt to earn the least punishing punishment, and perhaps he could even coax the young Alpha into sex of some sort still, libido dampener notwithstanding.
He lowered his eyes to the desk in a show of humility. "How can I prove my...my obedience, Alpha?"
Harry was silent for a moment, but Severus did not look up. "You're such a clever man, Omega. What do you think I'd like to see?"
Severus considered for a moment, turning a few possibilities in his head, seductive poses and displays of humility. He finally decided that the most obvious course would be the best one--the position most natural to an omega. There was something about kneeling prostrate on the floor that made an Alpha immediately more prejudiced in his omega's favor. And Severus had an inkling that he could use all the help he could get. Slowly, so he could be reprimanded if it wasn't what his Alpha was looking for, he rose slightly from his seat, slick uncomfortably sticking the fabric of his clothing to his skin. He sank to his knees beside the desk, head lowered and legs automatically spread. He clasped his hands behind his back, as it was still a fight not to attempt to rub himself after the movement sent a delicious friction between his hard cock and damp trousers.
"Good start," Harry said approvingly. Severus tried to ignore the surge of pleasure that came from his bonded Alpha's praise. "But I think your place is by my side, not all the way over there."
Severus started to rise to walk over but a noise of disapproval stopped him and he glanced up. Harry shook his head. "I still like you on your knees, pet," he said, his voice low and deepened with a natural authority.
The joy of hearing the term of endearment and embarrassment of crawling across the stone battled within him, both emotions turning his pale face a mottled red. "Yes, Alpha," he murmured and slowly crawled across the floor, stopping just beside Harry's chair and assuming the same humble position, head down and knees spread, another gush of slick pouring out of him at the rightness of the setting.
He felt a hand briefly smooth over his hair, warm and comforting, before withdrawing. "Good omega."
Severus couldn't quite suppress the quirk up of his lips at the show of affection. It embarrassed him still to feel this needy around anyone, even outside of the sexual needs brought on by his heat. But he wanted to be petted and praised by Harry, he wanted to earn his approval and affection. But he'd still not fully come to terms with that want, and it was easier to shift focus to the more immediate sexual desires, which had not not abated in the slightest. In fact, his arousal had only grown at nearness to his Alpha, his omega body not understanding that this Alpha apparently wasn't currently driven by the overbearing need to fuck him hard and knot him as many times as possible. Severus shifted again at the fresh rush of slick, his trousers tented by his full erection and uncomfortable both from the tightness and the dampness.
Harry seemed to notice and relish in his discomfort. "As much as I enjoy seeing you wriggle around in those clothes, I'd more like to see you out of them." He tucked a sweaty lock behind Severus' ear and the omega resisted leaning in to the touch. "Are you wet, omega? I could smell you from across the room. Is your prick hard?"
"Yes, Alpha," Severus said with a groan. "I am in heat, as you are well aware."
"Let me see then. Strip," Harry ordered. Severus quickly moved to comply, but before he'd undone the first button, Harry added, "No magic. And no getting up off the floor."
Severus made quick work of the outer robe, but was more than a little humiliated that he had to wiggle out of his trousers and maneuver himself in a most undignified manner, flopping around on the floor like a fish. He scowled at the indignity, but before he could express his opinion on that, the burst of cool air against his heated flesh made him sigh, his treacherous body still thinking that his newfound nudity meant that surely fucking would commence sooner rather than later.
His nipples tightened to hard pink nubs in the dungeon air, and he could feel the slick drip out, pooling onto the stone beneath him. He reflexively tightened his hands around his thighs, wanting to touch his cock, finger his needy arse, but that would certainly raise Harry's ire, so he simply resumed his kneeling position and gazed up at Harry hopefully, awaiting further instruction.
"You can be so obedient when you want to be, omega," Harry said, casually stroking through Severus' hair. “Let’s get started on a little bit of training to keep you in the right mindset.”
Severus was too distracted by how nice his Alpha’s fingers through his hair felt to be as uneasy as such a suggestion usually warranted. Obedience didn’t usually mean pain. Pain he could handle much easier. “Obedience training” was typically humiliating, and the worst kind of humiliating, the kind that left him hot and needy.
Severus swallowed thickly. “What would you have me do, Alpha?” he rasped.
“What was it you always told us about the menial, repetitive tasks you assign in detentions–cleaning cauldrons and such. It builds character?”
“My cauldrons are all pristine,” Severus deadpanned. “Unless you intend to have me write lines?”
“I’m sure I’ll have reason to make you write lines in the future, but watching that won’t be very fun for me,” Harry said. “No, something a little more visually appealing, I should think. We need to test your self control as well as your obedience.”
Since none of this sounded like it would get him any closer to being fucked or at least sated in any minor way, Severus let out a small groan of frustration.
His Alpha gave his hair a quick, rough tug in response. “And we need to give you something to do with your mouth besides grumble and groan.”
That was a little more inspiring. Severus was immediately drawn to the bulge in the Alpha’s trousers. Libido dampener or not, there was no way he could prevent being affected by the onslaught of please fuck me now omega phermones that Severus was surely drowning him in. Sure of what he was going to be instructed, he moved forward to release his prize from the confines of fabric, glad at least he’d be getting cock somewhere.
“Uh-uh, not so fast, “ he said. Severus’ hair was still gripped between his fingers, and he felt a sharp pull back and away. “You certainly haven’t earned that yet,” he chastised.
Severus had no idea how in the world a young, healthy Alpha was able to exert this level of control over himself. It was honestly a little offensive at this point. “Please, Sir,” he whined, hoping to sway him. “I’d very much like to show my obedience with my mouth.” He tried again to lean forward, the scent of his Alpha so intoxicating to him his mouth was already watering, but a quick slap broke his focus.
It hadn’t been painful really, just surprising, though the skin on his cheek smarted for a few seconds after the contact.
“All the more proof you need some additional discipline,” Harry said, deep and commanding, and Severus shuddered at the tone, the reminder of dominance causing another wave or arousal to roll through him, another rush of slick. “Back straight, up on your knees, grip your wrists behind you.”
Severus assumed the position he’d been commanded, digging his nails into his wrists in an attempt to ground himself. He took in a few deep breaths, in and out, and waited for further instruction.
Harry cupped his face where he’d slapped him, the gentleness of the action so unexpected, Severus faltered for a moment before righting himself. “What are you?” he asked gently.
The question threw him off guard. “An omega?” he ventured.
Harry waited for him to go on.
“A very randy omega?” Severus added, not sure what he was looking for but deciding he’d speak the truth, at least.
Harry chuckled. “That’s very obvious. Whose omega?”
“Yours, Alpha,” Severus responded immediately. “Your extremely randy omega, suffering untouched through his heat, in case you hadn’t noticed.”
The bit of backtalk didn’t seem to bother Harry. It never did, the man appeared to actually enjoy a bit of wit and sarcasm, as long as it wasn’t directed at him or his friends.
“Well, I want my very randy omega to show his self control. Instead of writing lines, you can repeat a phrase and action…let’s say ten times.”
Severus was immediately suspicious. That didn’t sound difficult. Even if the “action” was something painful, ten of whatever he could do to himself didn’t seem too bad. He fixed a curious gaze on his Alpha, sure he would go on to elaborate.
He then moved both hands over Severus’ body in a slow, calculated way. Fingertips grazing down the sides of his neck, down his chest, thumbs circling over each nipple twice, a quick pinch to each, then down, slowly, achingly slowly, straight down over his stomach and to his groin before skirting down the center of the tops of his thighs, a single finger on each hand extended to barely graze along the hard length of his cock. He held himself completely still, though he wanted nothing more than to thrust up, desperate to gain some friction along the heated flesh.
“Alright, now you repeat what I just did. Just as slow, just as controlled. Your needy body is touched as much or as little as I want. What you want isn’t important right now.”
The touches themselves were so light they would do very little to arouse him on their own, but the fact that he was being ordered to touch himself in such a seemingly arbitrary and highly specific way made him dizzy with the sensation of the Alpha’s control over him. He clumsily copied the movements, Harry gently guiding his hands from straying and reminding him of the path he’d set out.
“Very good,” he said and Severus flushed at the warm approval. “Now, you’ll do just that, then move your hands behind you and grip your wrists again, and then you’ll repeat the phrase ‘I’m your needy little little cockslut with no self control’. Then, you’ll start again. Ten times. Do you understand?’
Severus’ mouth was uncomfortably dry. He licked his lips. “Yes, Sir.”
“What’s your phrase?”
“I–I’m a–I’m your needy little cockslut with no self control.”
“Good boy,” he responded, and nodded at him to go on.
The first and second times were easy, Severus more focused on remembering the specific movement than what he was doing, but on the fourth pass, he rubbed his nipples for an extra motion than the permitted quick pinch and Harry clicked his tongue. “Nope. Hands behind your back.”
“I’m sorry, Sir,” Severus said, returning to his original position.
“That’s why we’re training you. Because horny bitches with no self control need to learn obedience, isn’t that right?”
Severus nearly whimpered at that.
“Alright, again. When he finished perfectly and repeated his phrase, instead of the expected ‘four, again’, Harry said ‘good, that’s one.’
“One?” he said in disbelief.
“I expect ten in a row. It isn’t my fault if you’re so mindless and horny you need so many practice runs.”
Again he started, perfectly obedient three, four, five more times. But the agonizing slowness was grating on him, and he apparently made the mistake of rushing through.
“We’re going to be at this all night at this rate,” Harry said in an insolent, amused tone and Severus wanted to throttle him.
He was made to start again halfway through when Harry had been cruel enough to tell him how hard his distress was apparently making him, and Severus faltered by fully stroking his own needy prick instead of keeping to only the light, one fingered motion he’d been allowed.
“You’re lucky I’m only expecting ten,” Harry said, almost conversationally. “Try to tell me you’d allow a student to turn in ‘a hundred' lines when half of them are illegible.”
Severus just glared. He was on number eight now. Well, twenty something by now, at least, but eight in this run and he was going to be damned if Harry was able to rankle him enough to lose focus again. He’d finally found the right motivation to get through–-spite.
He continued. His hands were shaking but he did the right motion, the right speed. Stuttered a little over declaring himself a needy little cockslut yet again, but he said it.
When he finally heard “Ten. Very good, Omega,” he felt exhausted, his muscles trembling from forcing himself to stay steady. It had taken long enough to get through that the insistent burn of his heat was only getting stronger, the need to be mounted and fucked impossible to drown out at this point.
“Please, Alpha,” he finally said in response, allowing himself to relax out of the straight back position and seeking some mercy. “I need–please he said, hoping the ‘need you to fuck me’ was obvious even if left unsaid.
Harry pulled him closer and wrapped his arms around him. “You’ve been doing very well for me,” he said, and Severus buried his face against his warm robes. Harry stood up from his chair. “That part's through now. Follow me over to the desk, hands and knees.”
Severus shuffled over in a crawl, following behind Harry as he led him to his own large desk at the front of the classroom.
He was pulled up on his desk by the Alpha’s strong arms and positioned on his hands and knees with the command to keep still. He trembled as Harry just gently touched him all over, stopping to pinch a nipple, tickle down his flanks, and fondle his bollocks. This gentle foreplay might have felt boring preceding normal sex, it wasn't nearly as intense as he liked it, but while he was in heat, and after so much teasing already, every touch and stroke and pet, no matter how feather light, just added to his frustration.
Severus whimpered when Harry stopped the light stroking along his perineum. It was so close to where he wanted to be touched but the alpha just chuckled when Severus attempted to shift himself so that Harry's fingers would make contact with his clenching hole.
His legs were shaking with the effort of holding still when his Alpha gripped his hips and used his thumbs to lightly massage the round globes of his arse, agonizingly similar to the position he'd be in if he were just being fucked already.
"Alpha, please," Severus finally bit out. "No more teasing, please."
"Poor omega," Harry said in a cloying, mock-sympathetic tone and Severus gave another frustrated whine. "You have been good for a while though, despite how desperately needy you are." Severus heard the muttering of a charm and Harry's fingers encircling the base of his cock. The orgasm denial spell, he'd been the recipient of that before. But this time there was a glimmer of hope. Perhaps it was that just to ensure he wouldn't come since he was still being punished, but Harry had changed his mind and decided to fuck him?
He glanced back and apparently hope was written all over his face because Harry smirked mischievously. "I'm going to the loo. You stay here and be still and you might get rewarded for it."
Severus groaned. "Yes, Alpha," he said with a rather undignified whine to his tone.
He raised himself a bit to get slightly more comfortable when Harry disappeared. He glanced around, fidgeting. He hoped Harry had remembered to ward and lock the door.
He knew he should be chilly, naked in the dungeons but all he could feel was the oppressive warmth burning under his skin. The way his dark red cock bobbed with every shift, he could see a literal pool of slick and precome beneath him, his cock and arse were dripping so heavily.
He tightened his hands into fists. Although he did desperately want to touch his cock, it wasn't just the burn of sexual arousal that was driving him, it was his omega instincts to be mounted and fucked, to be filled and stretched open to the point of pain.
To that end, it was his arse that was most desperate, desperate to be penetrated, the rim widening around an alphas large cock. Or failing that, something. A toy, fingers. Merlin, a potions vial would suffice at this point.
Severus moaned, low and deep as he tried to clench his hole tightly in a useless effort to sate the agonizing need. He was in no danger of coming without permission, not with the spell on, but he was desperate for something in his arse. It felt so empty, so needy, and as the minutes ticked by and Harry was still not here, Severus was getting increasingly more desperate.
Maybe if he just used his fingers to press against the rim, the pressure would alleviate some of the ache. He'd never had a heat on his own before. He'd suppressed every one until his claiming heat with Harry, and though he'd been denied orgasm through some, he'd never been denied his alpha's cock!
He didn't realize the extent of desperation, this deep, pulsing ache at being empty, the longing to be filled and stretched wide, full and deep.
Determined to simply press and rub against the rim for a few moments while his Alpha was gone, he reached back and felt for his arse, slipping his long fingers through the thick fluid before finding the spot he needed to touch most.
The slight press of his own fingers was heavenly, despite not being the ideal solution it did nonetheless feel wonderful. But Severus had overestimated the control of an omega in heat and a moment's touch to the rim quickly gave way to him burying his finger in the warm, wet hole. Then a second, and a third, needing to feel the pleasant burn, the stretch of being forced open.
The angle was awkward and his shoulder was bent uncomfortably but he paid it no mind, lost in the pleasure of finally feeling something in his arse. He quickened his movements, falling down to balance his efforts on one arm while he spread his legs wider, trying to force his fingers as deep as they would go. He felt a jolt of electricity as he brushed his prostate. He let out a loud moan at the contact, then desperately tried to recreate the angle, thrusting his hips back to meet his wildly moving fingers, grunting at squelch of skin against slick, chasing his pleasure with a single minded intensity…
"Well, look who decided to be naughty instead," Harry's deep alpha voice cut through Severus' focus and he scrambled to right himself, withdrawing his fingers with an ache at the loss. “And what did we just learn about self control?”
“I’m–I’m sorry, Alpha, please–forgive me, please,” Severus panted. His arousal hadn’t dampened at all, even with the threat of an angry Alpha. He shook with need, the brief finger fucking had only made the ache so much worse, reminded his body of what it was craving, what Harry was so cruelly denying him.
"It barely took five minutes for you to reveal yourself as a wanton little slut who can't keep his fingers to himself."
Severus dared to look up at him, at the penetrating green gaze. Distantly, he realized he'd never heard the door opening again. Had he ever left? Had he just been waiting for him to break down and disobey? He whimpered, disappointed in himself for his lack of self control. "Please, Alpha," he whined. "I'm so–so needy." He felt like he wanted to cry from the unabating arousal. "Forgive me?"
Harry circled the desk, touching him at random, squeezing his buttocks, scraping his fingernails down his buzzing skin. "We need to punish your needy arse," he declared.
Severus pulled his knees in, raising his arse high in submission to whatever was coming. "Yes, Alpha. Punish your cockslut."
Harry was still leisurely in his movements. If Severus had the ability at the moment to be more perceptive, he'd have realized he had expected him to fail. Been counting on it, perhaps. "Do you want to know how I would have rewarded an obedient omega who stayed still and kept his hands off of my property?"
Though no good would surely come of it, Severus couldn't help but be curious. "H–how, Alpha?".
He chuckled, stroking softly along the cleft of his buttocks, rubbing along the flesh and skirting the outside of his rim without touching him in the way Severus so desperately needed. "You would have earned a nice, long tonguefucking." Severus let out a loud, unhappy moan at that declaration.
"That's right, poor boy." Harry said with mock sympathy. Severus could feel warm breath against his backside and he shook with anticipation at just the idea of it. He'd been introduced to rimming by his Alpha and even though he'd only experienced it a few times it was quickly cemented as a highly sought after treat. "Bet that would have felt good," Harry added, rubbing in the taunt while massaging the omega's tightly tensed inner thighs. "Imagine it, your poor, needy hole getting licked and sucked hard, your desperate arse eaten out until you were a whimpering, shaking mess. My hot tongue working into you." The Alpha had moved up to Severus' head, so he could whisper the next cruel words directly into his ear. "I wouldn't let up even if you were screaming. Just keep chasing the taste of you, listening to you cry out in pleasure, nibbling the edges of your naughty hole and sucking the sweet slick out of you. Wouldn't that have felt nice?"
Nice didn’t even begin to describe it. Severus wanted to start crying at the thought of how much he wanted that, how amazing it would feel. He didn't think Harry was lying either, he isn't the type. "I'm sorry, Sir," he said. "I don't–I don't deserve that."
"Not tonight at least," he said, smoothing down Severus' sweaty hair in a show of comfort. "Your needy hole got you into trouble, so what does it deserve?"
"To be punished, Alpha." Severus gasped out.
"Do you need to be tied into position or will you take what I give you without moving away?"
"I'll be good," Severus answered. "Please, Alpha. I'll be good for you." He moved into a steadier position, still on his hands and knees, but more centered on the desk, his arse in the air and waiting.
"I'm going to paddle your bum until it's red and nicely bruised," Harry announced, summoning an implement to do just that. "And then, since we need to punish your naughty, greedy hole specifically, I'm going to strike it right on the rim as many times as it takes until I'm satisfied. Do you understand?"
Severus nodded, gripping the wood beneath him and readied himself, determined not to disappoint Harry again. "Yes, Alpha," he said shakily. "I'm ready, Alpha."
"No need to count, but you'll thank me for disciplining you when I finish."
The first few hits of the paddle were varied in position and relatively light as Harry adjusted his swing and angle. Severus took the stinging pain in stride, not making a sound beyond sharp intakes of breath.
Once his Alpha found a comfortable rhythm, however, the paddle landed harder and harder. He swung at the meatiest part of his flesh, over and over in the exact same spot, a loud smack every time until Severus is crying out.
"This side is a nice dark red," Harry said, giving him a brief respite as he kneads the tender flesh. "Now to match." He repeated the process on the left side, striking the middle of his buttocks enough that Severus will surely have deep bruises that last for days. As painful as they are, the omega already knows he's going to savor the deep ache every time he tries to sit down.
"Ah!" Severus cried out as another hit of the paddle lands, hard. "Hurts, it hurts Sir, please--ah!" Tears streamed down his face as he tried to focus on what he's saying. "Thank you. Thank you, Ah-Alpha, for punishing me."
After another firm stroke of the paddle that nearly sent him off balance, Harry set it aside. "Shhh, omega. Very good. You did very well for me," he ran a comforting, gentle stroke down his back as if quieting a mare.
Severus trembled under the petting. His pain tolerance was naturally high as an omega but he still trembled, overwrought with the way his heat intensifies every sensation, the constant arousal and the aching need still burning in him.
"Just one last part, and then it's over," he said soothingly, and Severus nods, sniffling and blinking away tears. "We need to remind your greedy hole who it belongs to now."
"Yes, Alpha. I'm ready, Sir." Severus took a deep breath, then maneuvered himself so he could reach behind and present himself for the rest of the punishment. His arse was already so sore, once the bruising set in they would be even more painfully tender. He pulled the flesh roughly, enjoying the hot pain of manhandling the bruised flash and hissed. "Please–Please crop my greedy hole, sir."
"I'm very proud of you," Harry said quietly, and Severus felt the press of a few quick kisses to the abused flesh. Severus was dizzy with the show of tenderness. Harry was a very strict Alpha, but moments like this reminded Severus he actually cared for him too. It was confusing when he considered this in the light of day, but through the haze of heat and pain, Severus just sunk into the simple joy of it.
"Th–thank you, Sir."
He howled at the first hot sting of the crop on his oversensitive hole, but he held position. Another hit of the leather landed, hard and quick, over and over, one on top of the other.
He was glad he wasn't tasked with keeping count, as he wasn't sure he could if he tried. After several more hits, he felt like he was on fire and his voice was rough from crying out. His arms were shaking with the effort of continuing to hold himself open for further abuse.
"How does it feel?"
"H-hurts, Alpha," he gasped, fully crying now. "It's so hot and sore, and it aches. I–ah, ah, still need you, need to be fucked but it hurts. Th–thank you, Alpha," he added, remembering the initial command.
He heard the light crop being put down, and Harry gently removed his stiffened hands from their position spreading himself apart, rubbing away the ache in his wrists.
"You took that very well, omega," his Alpha praised, and helped him settle into a more comfortable position resting partially against him. Severus felt wrung out from his exertion and the punishment, but the deep seated need that came along with his heat was still boiling away within him and he whined at the frustration of the continued emptiness of his burning hole.
Harry groaned, and Severus felt something thick and hard grinding at his side through the Alpha’s trousers. “I can smell how aroused you still are. You’re driving me crazy.”
“I am–at your service, Alpha,” Severus panted. “I’d beg you to fuck me, but I understand my–my punishment.” He moaned morosely, despite the world of pain his backside was in, he was still frenzied with the need to be mounted and pounded into, hard and deep.
“You’d really still beg for it?” Harry asked. “Even bruised and sore, inflamed from cropping, your slutty hole wants to be stretched open over my cock and pounded into?”
Severus shuddered. “Yes! Yes, please Alpha, I need it.”
“I wouldn’t be gentle,” he warned. “In fact, I’d want it to hurt worse, so you remember what an insatiable animal you are tomorrow, when you can’t sit down without wincing.
“I wouldn’t want you to be,” Severus said in a rush. He was trembling in anticipation, the hope that Harry might have changed his mind about his original punishment aglow within him. “Please, Alpha, fuck me hard, make me scream.”
The Alpha’s eyes were dark with arousal, and he studied him with an intensity that made him shiver. He saw his eyes flick over to the back wall, and then he smiled.
“Well, I don’t want you thinking I have a habit of going back on my word–if I declare you’ll be punished you are going to be.” Severus wilted. “However–” he said, “I’ve always been a fan of bending the rules.”
“Sir?” Severus asked, confused.
“I said I wouldn’t be fucking you until tomorrow. And it is, uh,” he indicated the clock behind them, “just on tomorrow, isn’t it?”
Severus immediately put on the best show he could muster, getting back down on forearms and knees and wiggling as enticingly as he could manage. “Please, please, Alpha, I need it, please. Fuck me!”
“You’re still not allowed to come. That's non-negotiable,” Harry said sternly, as he quickly divested himself of his trousers, his enormous cock springing free.
Severus whimpered, but before he could respond with a “yes, Alpha”, his mouth was occupied by cock being shoved unceremoniously into it. He took his cue immediately, sucking hard at the dark head, laving his tongue all around and licking up the slightly bitter taste.
“That’s right,” the Alpha said, gripping Severus’ hair tight to the point of sweet pain, “suck. Not that it needs any lubrication, what with the fountain of slick you’re pouring out.”
Severus moaned around the head, taking him in deeper, swallowing around him and attempting to communicate the extent of his desperation through cock sucking alone.
“Fuck,” Harry said, finally pulling him off. He swung around and had Severus pulled down off the top of the desk and bent over it in a matter of seconds. He roughly shoved him up against the edge, his hip likely bruising in the process, but Severus didn't care, all he could think about was that need, that deep, cramping ache, that could only be sated by on thing, what he needed more than anything—
“Ah!” Severus cried out as he was speared open on a thick Alpha cock. Harry gave him no time to adjust, fucking into him like a wild animal. He didn’t even allow him time or space to readjust himself, slamming him hard against the desk as he scrambled for purchase. “Yes! Yes! Hurts, oh, need more, more, harder–”
Severus was babbling, lost to the white hot pleasure pain of his sore arsehole so forcefully stretched open, of his poor, bruised bottom being battered by the smack of his Alpha’s body behind him, every new hit accompanied by a flash of bright hurt.
“So tight, ngh, you drive me mad,” Harry growled, thrusting into him without respite. He reached around to Severus’ front, clasped the aching hard prick in his hand and rubbed roughly.
Severus cried out in surprise, the pleasure cresting quickly and then immediately aborted by the denial spell Harry had put on him earlier. He nearly sobbed in frustration, but he knew better than to beg for a respite from that. His Alpha preferred him desperate and frustrated after all.
“Maybe you’ll come tomorrow,” Harry grunted, “If I decide I want you to.” He dug his nail into the sensitive glans hard enough to make Severus scream. The stinging pain of the action coupled with the reminder of the man’s control over his body caused him to clench hard around the Alpha’s cock.
At that Harry’s thrusts stuttered and he came with a deep growl, nipping at the claiming scar on Severus’s shoulder, nibbling the shiny skin as Severus tingles all over.
Harry gave Severus’ prick a few harsh twists as he knotted, and Severus involuntarily clenched several times around the thick hardness, milking the knot. A new burst of delightful, hot pain burst through him every time his inner walls clench and loosen around it.
He was still unbearably aroused, and he wanted to come so much it hurt, his whole body shook with the need of it, his swollen bollocks attempting to find release only to be beaten back by the cruel spell. But something within him was still sated, a deep itch finally scratched, the rightness of being forced open and filled giving him a delirium of pleasure.
Harry nuzzled his neck from behind and lifted him enough off the desk that Severus could release his pinned down arm. He felt himself being pulled backward as Harry settled into his chair, maneuvering Severus so he could lay half against him, pinned in place by his Alpha's cock as they waited for the knot to go down. Every jostle of his body sent a new wave of intensity through him, pain and pleasure so thoroughly mixed it was difficult to differentiate the two. Severus moaned feebly as Harry continued to stimulate his denied prick. Apparently the little moans of frustration and internal clenching this caused makes the knotting phase of coitus all that more pleasurable for his Alpha, as Harry sighed in bliss every time Severus wriggled from the overstimulation.
“I like detentions a lot more when they end like this,” Harry said sleepily, and Severus scoffed.
“With fucking me or with tormenting me?
“Oh, both,” Harry answered. “I’m never going to stop fucking you, and you are never going to give me a reason to stop tormenting you.” He punctuated the sentence with another nip to Severus’ throat, soothing over the scar with a soft kiss.
Severus settled back against his Alpha, resigning himself to the idea that this was probably true.
