The dungeon air was cold and damp, the scent of mildew ever present, though Remus doubted the other students noticed. Another curse of being a werewolf he supposed. His heightened sense of smell was both a blessing and a curse.
He snuck a sideways glance at Sirius to his left and inhaled. Ah, that’s better. The warm and faintly musky scent of the larger boy was a welcome reprieve. He could breathe in Sirius’ scent all day. It was heady and masculine, his musk deepening as the day went on, strongest after he had been exercising and sweating. Remus felt a small jolt in his belly which transformed into cold shame sliding up his spine. He didn’t want to think about that, not here. But his brain wouldn’t obey him and crept onward to memories Remus kept hidden until he was alone.
Smelling Sirius’ used shirts, his dirty laundry. The pair of stolen boxers he kept at the bottom of his trunk that smelled of sweaty, musky cock and the slightest hint of piss. He felt his cheeks redden as he tried to quell the thoughts of taking his own cock in hand and thrusting into his fist wildly. Coming with abandon on his four-poster bed in the middle of the night, a silencing charm hiding his shame while he pressed the crotch of Sirius’s used boxers into his face. Moaning, nuzzling and licking them, imagining the faint taste of Sirius was the real thing. Sirius’ fat swollen cock dripping into his mouth.
Stop! His brain shouted and he hung his head lower over his desk hoping his hair would hide his glowing cheeks as he forced his mind back into the dungeons. As he bent forward, he felt another jolt in his stomach, but this was something else. He grit his teeth as his sudden awareness of his straining bladder.
He knew he should have released before potions; knew he had been overfull after lunch. Knew he shouldn’t have held it since before bed last night.
This was another of his secrets. He got off on it. Being full to bursting made him feel like he was right on the edge. He craved the sweet relief that came with releasing a hot and desperate stream of piss. It was almost as good as coming, sometimes better. He was too full now though. He had left it too long.
His dick felt heavy between his legs, swollen and thick with his piss. His whole shaft felt full from the base to the tip. He pressed his thighs together squeezing his piss-hard cock between them, clamping down on the need to release. Ah, that’s better.
The pressure on his bursting cock made him feel like he could hold on until the end of the lesson at least. Glancing up, he tried to figure out how much longer they had left. It was hard to tell without windows to gauge the time. Fifteen… maybe twenty minutes? He hoped he could hold it.
He felt another familiar jolt in his stomach and before he could stop himself, he pressed his left hand to his lower belly feeling the generous swell of his bursting bladder as it strained against the waistband of his pants. His bladder spasmed again under his hand. Suddenly the pressure on his cock didn’t feel like nearly enough and he squeezed his thighs tighter on his swollen shaft with a sharp inhale.
A low whisper brought him back to reality with a start. “Moony, are you OK?”
He glanced sideways at Sirius, making momentary contact with the larger boy’s dark eyes which were wide with concern.
“Does your tummy hurt?” Sirius asked, his voice barely more than a murmur. It wasn’t wise to attract Professor Slughorn’s attention if you could help it. The enormous man didn’t know when to stop talking.
“Uhhh, yeah…” he whispered back, his voice strained. “It hurts.”
“Is it bad?” Sirius asked in that low murmur, his voice intense, worried. “Do you need to go to the hospital wing? I can take you.”
Remus shook his head just barely. “It’s OK.” he managed to groan out quickly.
His distended bladder felt firm beneath his splayed fingers. The hard pressure of his thighs on his thick cock wasn’t enough, but it was as tight as he could press. Without thinking he started rocking slowly back and forward in his chair, his agitation growing.
He needed to grasp himself to quell the urge, or he knew he was going to spurt. His cock felt even heavier than before, like his piss was inflating it. Maybe it was just the feeling of being on the edge, of rocking his swollen length between his thighs, of anticipating the release that was making him half hard. It usually did. Good he thought, that should help me hold off, at least until potions is over.
He felt Sirius’ voice again. It was closer this time and Sirius’ upper arm pressed against his own. “Are you sure you’re OK?”
Sirius’ breath was hot in his ear and at that moment he felt it. A dribble. Just a little. From his slit. A sharp breath escaped him and instinctively his right hand reached for his cock. He gripped himself tightly. He couldn’t dribble again. He wanted to moan at the relief the tight grip of his fist brought but he held it in. He couldn’t stop himself from breathing heavily though, panic coursing through his veins. Sirius was going to see. Sirius was going to know.
He glanced down at his crotch where his hand was pressed hard around his thick shaft, searching for the evidence of his dribble. But there was no wet spot on his grey uniform pants, and he breathed a sigh of relief.
Sirius’ breath was in his ear, hot again, “Do you just need to piss? It’s not your tummy?”
Remus shook his head slightly, gripping his cock harder.
“Why don’t you just go to the loo? Do you want me to ask Slughorn if you can leave?”
“No!” Remus whispered back quickly. “I can’t Sirius. If I move my hand now, if I stand up, I’ll piss myself.”
He felt his half hard cock twitch at the thought of release and gripped it tighter as he felt another small dribble escape him.
“Oh.” said Sirius and Remus felt his chest tighten with horror and shame.
The silence between them stretched out and Remus’ eyes never left his crotch. There was still no wet spot on his pants and then Sirius was whispering again.
“Do you think you can hold it in until the end of the lesson?”
Remus nodded almost imperceptibly. “I have to.”
The tip of his cock felt very wet, and he knew a tiny pool of piss was collected in the little hood his foreskin made around his cockhead. That was what was stopping the piss from wetting the front of his pants. He knew if he spilled one more drop his foreskin wouldn’t be able to contain it.
The seconds ticked by slowly and the hard grip on his cock didn’t feel like enough anymore. He shifted in his seat. He felt like he was going to flood his pants any second. His muscles strained to keep his bladder from releasing, and he knew his breathing was laboured. He could almost feel Sirius’ concerned eyes on him, but he didn’t look up from his crotch. He was going to leak again. He knew it.
He tried to grip his swollen length tighter. It was hurting now. Everything was hurting. He grit his teeth together as a hot squirt of piss escaped and watched a dark wet spot spread instantly in the crotch of his pants just at the tip of his throbbing dick. The sharp smell hit him immediately.
He felt Sirius jolt beside him, but he didn’t, he couldn’t look up. His cheeks felt like they were on fire, and he gulped in shame. The wet spot was about the size of a galleon and quickly cooling against him, outlining his fat wet cockhead where it lay in his lap, emerging from under his tight fist.
He clenched his muscles again, willing himself to hold in his piss. He wasn’t sure he could. If he spurted again, he might not be able to stop. He might flood his pants all the way down to the seat underneath him until he was sitting in a puddle. He was so full. It would splash onto the floor in heavy wet streams and fat droplets. Everyone would see and everyone would know.
He gripped down harder on his cock, almost panting now but trying to keep it quiet and avoid attention. He shifted in his seat again to ease his desperate urge to release and felt his bladder spasm too late. Another hot spurt escaped him, more this time. He watched in horror as the dark wet spot spread across his crotch. Proof of what he had done, what he was doing. He clamped down harder. He was going to piss his pants.
He felt movement at his side and the hot feeling of shame intensified. Sirius is watching, Sirius knows. He couldn’t look up. He stared at his wet crotch, the soaked material clinging to the head of his cock and the tops of his thighs.
He kept watching, mesmerised as a strong masculine hand entered his line of sight and reached for his cock. Thick fingers pinched his tip, closing his slit. He almost moaned with relief at the touch as the urge to piss dulled a bit.
Sirius’ fingers were large and strong. They pinched his swollen cockhead tight through his piss-soaked pants. He rocked his half hard cock into them before he knew what he was doing. It felt incredible.
Sirius’ hot breath was at his ear again. “It’s OK Moony I’ve got you, just hold on a bit longer, OK?”
He stopped pushing into the strong fingers instantly, but Sirius murmured again “It’s OK, if you need to.”
He rocked his hips forward slowly again, careful not to move too much. He didn’t want to attract attention. He felt his eyes roll back at the feel of thrusting his half hard cock into Sirius’ thick fingers. The wet material of his pants added to the delicious friction. It’s not how he had imagined Sirius would first touch his dick but it was better than anything he had ever felt before. Better than any fantasy.
He still needed to piss desperately. Sirius’ fingers clamping down on his tip were the only things keeping him from jetting a hot thick stream into his pants.
He whimpered slightly and Sirius murmured, “It’s OK, potions is almost over.”
Remus raised his eyes for a second, blinking. In his desperation he had almost forgotten where they were. He was in potions, thrusting his half erect dick into Sirius’ hand through his piss-soaked pants. The other students were packing their things away, Slughorn was already gone.
“I can’t hold it any more Sirius.” he whispered, his voice panicked.
“You can.” Sirius replied firmly. The hot breath in his ear made his stomach twist and clench and a small squirt erupted from his slit even though it was tightly clamped between Sirius fingers. He was pissing on Sirius' hand.
He clenched down immediately but it wasn’t enough and another hot little spurt then another escaped him before he could stop them. Sirius’ fingers never moved from their spot at his tip, never stopped their insistent grip on his cockhead even as beads of piss dripped from them onto his soaked pants.
He could feel piss leaking from him in a thin stream. It soaked down between his thighs, wetting his balls and the seat below him just a little and when he shifted slightly, he felt the dampness spread through the seat of his pants.
He felt his cock pulse again. Another hot spurt of piss, larger and more forceful this time, jetted out from between Sirius’ fingers, squirting through the material of his pants and splashing down on his thighs below the desk.
“Moony.” Sirius’ voice was urgent in his ear. “They’ve gone. Let’s go.”
Remus looked up. The room was empty, and the harsh sound of his breathing echoed in his ears. “I can’t.” He whimpered. It was too late for shame now. “I can’t Pads, I can’t. I’m going to piss myself right here. I’m going to piss all over your hand.”
His cock was leaking steadily now, piss incessantly seeping from between Sirius’ fingers. His arse felt wetter and wetter with each passing moment as his piss soaked the seat beneath him.
“OK, OK.” Sirius said soothingly and Remus heard his chair scrape back. Then Sirius was kneeling next to him, half under the desk. Sirius reached for his zip just to the side of his swollen piss-hard cock. The sound of the zipper was loud in the empty classroom and Remus whimpered as Sirius reached inside his soaked pants searching for the opening in his boxers. His thick fingers found it quickly and, in an instant, he was inside. He brushed his large fingers against the base of his cock, grazing through his piss-soaked pubes and Remus moaned loudly.
“Shhhhh!” said Sirius desperately. “I need to get your cock out so you can piss.”
“I can’t piss here.” he whimpered. “On the floor?”
“No.” said Sirius, withdrawing his big hand from inside his wet pants and grabbing for his satchel. He reached blindly inside and pulled out something. An empty firewhisky bottle. No. Not empty. There was a tiny bit of liquid at the bottom, too light and too yellow to be firewhisky.
“I keep this for emergencies.” the dark-haired boy said looking up at him, a flash of something unreadable in his eyes. “You never know when you’re going to need to piss.”
He brought the bottle up to his mouth and used his teeth to unscrew the cap, spitting it onto the dungeon floor where it clattered away. He placed the large bottle, empty except for the dribble of his piss on the floor next to him. Still gripping Remus’ cockhead tightly outside his pants, Sirius reached into his boxers once again.
“You have to let go Moony. I have to get your cock out and then I’ll help you piss into my bottle.” Sirius said gently.
“I can’t let go Sirius, I can’t!” Remus moaned, knowing the thin trickle would become a gushing flood as soon as the pressure of his fist left his shaft.
“I’ve still got you.” Sirius said, flexing his thick fingers around his swollen tip. “You have to let go.”
Slowly, Remus unclenched his fist from around his cock, silently willing himself to stop leaking. Sirius quickly grasped his bare wet cock inside his boxers and slid his fingers down to the tip. As he released his grip outside the pants a huge leak gushed from him which Sirius quickly slowed by gripping his bare foreskin and clamping it down over his pulsing tip, squeezing his burning slit closed.
Remus moaned again as Sirius gently pulled his cock from his pants. His knees fell apart as he opened his legs, the tip of his cock firmly in Sirius' strong grasp. He watched Sirius pick up the firewhisky bottle and bring it to his tip. Smoothly the dark-haired boy released his squeezing grip and placed the fat and swollen head of his cock at the mouth of the bottle. The thin dribble of piss that had been leaking from him for the last minute trickled down the bottleneck mingling with the remnants of Sirius’ piss at the bottom.
He looked down at his half hard, piss-heavy, swollen cock. Two of Sirius’ thick wet fingers sat at either side of it, holding his tip at the glass mouth of the bottle. He whimpered. He was too full.
“I don’t think the bottle is big enough. I’m going to have to keep holding it, but I can’t.” He almost wailed.
“It’s big enough.” said Sirius firmly. He moved his fingers slowly up and down his shaft, pulling his foreskin back from his slit slightly with each pass as though he wanted to milk the piss from him.
Then he felt it. A hot stream erupted from him, spraying wildly into the bottle, hitting the bottom of it with such force that he felt it jerk in Sirius’s hand before the larger boy pressed it more firmly against his tip. Moan after moan escaped him and he thrust forward, grinding the head of his cock against the smooth glass mouth of the bottle.
“Fuck.” he moaned “Oh fuck yeah.” his stream was thick and hard, and it felt so good. The bottle was half full. It felt like no time at all had passed and his piss kept spraying, fast and hard. Two thirds, three quarters, it was rising up the neck and then he felt the hard glass retreat suddenly from his tip. He thrust forward, desperate to grind against it but the bottle was full and Sirius had put it down. He bucked into Sirius’ hand instead as the kneeling boy aimed his cock ahead of him. His thick stream burst out from under the desk splashing onto the flagstones in front of it.
“Oh fuck.” he moaned, writhing in his chair and thrusting his heavy cock forward as piss gushed out of him “Oh fuck, oh Sirius, oh fuck yes.” His stream jetted out of his slit with more force than it ever had. He pissed and pissed and pissed. He had never felt this good. It had never been this good before. He felt like he was coming and he knew his cock was swelling with arousal as piss continued to burst from him. His pulsing, pissing dick was raising slightly, the stream arching a little higher as he hardened with the overwhelming pleasure of his desperate release.
At last, his stream weakened. He watched Sirius stroke him slowly, still milking him as the piss arched from his tip less furiously now. It hit the ground closer and closer to him until it slowed to a gentle stream under the desk as Sirius massaged his shaft gently but insistently. Coaxing the piss from his throbbing dick. His cock was even thicker now, the uncontrollable pleasure of his release and Sirius’ milking fingers had made him stiff and engorged and his cock twitched, piss still leaking from it.
He groaned and watched as the strong thick fingers continued to milk him. He brought a hand to his stomach, pressing down on his bladder not wanting his stream to end. Not wanting Sirius to stop stroking his pissing cock. He needed to get every last drop out. He was getting harder with each pass of Sirius' fingers and he knew his piss would stop flowing soon. He was going to be so hard.
The dark-haired boy looked up at him with wide eyes, still milking him gently. With every twitch of his hardening dick a dribble of piss forced its way from his glistening head. When his wet cock was fully erect, he watched in disbelief as Sirius slowly leaned forward and licked the droplet of piss that beaded at his slit. It was the hottest thing he had ever seen. His cock jumped and trembled with arousal and he realised suddenly he was whimpering. Sirius had just licked a drop of piss from his hard cock. He writhed in his seat, pressing forward and watched Sirius lick him again.
Sirius' tongue was so hot and wet. It soothed his swollen tip as he lapped at it gently. His large tongue probed at his slit as though searching for another drop of piss. He rolled it around his exposed, sensitive cockhead, tasting him. Sirius was licking his cock. He couldn’t believe it. A tiny squirt of piss erupted from him at the sight of it and he watched Sirius’ tongue move to catch most of it as it hit his mouth. He moaned loudly and watched through eyes hooded with arousal as Sirius licked down his wet shaft, savouring him, cleaning up his piss.
"You taste incredible." the kneeling boy said as he drew back slightly, his voice thick. Remus stared at him, dazed. He noticed then that Sirius was gripping his own erect cock through his pants. He watched as Sirius ground hard against his palm. He couldn't believe what was happening. He smelt it then, the heady scent of Sirius' precum. His cock twitched again and another tiny droplet of piss seeped from his slit. Sirius' tongue darted out as he lent forward immediately and cleaned him again. His large tongue probed at him gently as though searching for more and he felt rather than heard Sirius groan, his tongue vibrating against his weeping slit. Remus moaned in bliss. It was too much.
"You feel incredible." he panted out as he thrust forward against Sirius' hot wet tongue. He wondered if he could push out one more drop. He wanted to see Sirius lick another yellow bead of piss from his slit.
Suddenly Sirius’ mouth was on him. His lips closed around his fat wet cockhead and he sucked hard. The insistent suck coaxed one last long dribble of piss from his throbbing dick. He watched Sirius swallow it down eagerly and he moaned loudly in pure ecstasy, thrusting wildly into Sirius' hot searching mouth. Now he knew there was nothing left.
