Chapter Text
Standing in front of his office door, Severus hesitated. Not only because he had a hard-on from hell but because he was wearing a fucking nappy on top of it!
He had to use Occlumency to keep his blush at bay.
And yet he didn’t want to vanish it. The soft padding surrounding his lower area felt warm (and excitingly sticky from his cum) and gave him a strange sense of safety he didn’t want to explore further right now. It was just … nobody could see or feel anything about that part of his body due to the charms he’d cast over the thing, whatever was happening down there was his secret.
A tingle rippled down his spine and with a last deep breath he finally opened the door and left his quarters to head to the Great Hall.
By the time he’d reached the stairs leading up to the Entrance Hall, though, he had to actively suppress his moans because the padding gently rubbing against his tender flesh felt just so bloody good!
And by the time he took his seat next to Minerva, he had to occlude harder to not act conspicuously even though the tightness of the nappy and his trousers against his hard cock was almost making him come again.
Why exactly had he decided to do this today?
Ah, right. Hermione had persuaded him. Plus it was bloody Monday! He didn’t want to wait for another five days to try this, not after the talk they’d had last night, not with Hermione knowing about his desire and not only being fine with him experimenting but actively encouraging him.
Ugh, her firm rubs against his front had felt unbelievably good … He hadn’t come so quickly in quite a while.
“Are you quite all right, Severus?”
He winced and masked it by reaching for the coffee. “Of course I am, Minerva. Why do you ask?”
“You seem a bit … distracted.”
“Just tired.”
“Bet you are,” Pomona mumbled from Minerva’s other side and stuck her nose into her teacup, not exactly hiding a grin.
Minerva smirked as well.
He scowled at both of them, silently bemused by how they would have reacted if they'd known what he was wearing underneath his usual black trousers. “Well, I’m a bit too young to go to bed at eight-thirty in the evening, am I not?”
“Depends on what you’re doing in bed …”
“I normally read a chapter or two,” he said sweetly, silently thinking about how he’d fucked himself against his bedpost last night to welcome Hermione home with the show she deserved. Both of you would faint if you knew …
But thankfully they didn't know and so his remark only elicited a snicker from his elderly colleagues, making him focus back on his breakfast, deciding to drink three cups of coffee this morning instead of the usual two just because he could.
And yet, walking by the loos on his way to class later raised his hackles. It just felt fundamentally wrong to not use his last chance before a two-hour-long class to empty his bladder – and potentially his bowels as well. But the nappy rubbing against his slowly hardening again cock made him clench his teeth and ignore the door.
He felt that wasted opportunity and his additional cup of coffee about an hour later when he had to gulp down a moan. Gods, he was filling up quickly … “Don’t blow up the castle,” he ordered his sixth-year NEWT class and went into the storage room to grab himself and give himself a quick rub that deliciously tingled through his crotch and caused his balls to tighten.
Should he do it now? Piss into his nappy for the first time?
He exhaled a hitching breath, his heart beating a mile a minute and his grip around his cock hardening again.
Mhh …
No. He would wait for a bit longer. It felt better when he was leaking against his will first. And maybe he would make it until the end of this class and have some minutes of privacy to savour the moment.
Taking his hand off his crotch he occluded hard again and returned into the classroom, mourning the dampening of his bodily sensations.
But that measure really helped him make it through class without a single leak although his bladder had to be short of bursting already. “Leave your potion samples on my desk and don’t dawdle cleaning up your tables!” he announced and feigned being absorbed in some notes while one student after the other passed him by and placed a small vial in front of him.
When the last student had left the room, Severus twitched his wand to close the door and placed a tiny ward on it that would give him some extra seconds to get his features back under control should somebody try to come in.
Then he leaned back in his chair and slowly, slowly loosened his Occlumency.
Fucking hell!
He gasped when the full extent of his condition seeped back into his perception. Gods, he was full! His fingers curled around the armrests of his chair and his legs spread on their own accord to give his straining bladder a bit more room. Quick, shallow breaths rushed through his nose while his eyes fluttered closed. It was a matter of seconds until his body would give in, he could already feel the first drops of piss tickle the tip of his cock, but he wanted to savour those seconds. The agony, the bliss, the pending release.
And then he leaked. A hot spurt of piss soaked into the padding, quicker than he wanted.
He bit his lip, allowing himself the first loud moan since he’d left his quarters almost three hours ago.
Another spurt, longer this time, shot from his tip, spreading hotly around his cock before being soaked up.
Fuck, he didn’t anticipate it feeling so hot. Literally! He’d assumed it would turn him on immensely but his piss was of an unexpectedly high temperature as well, almost like sitting down in a hot bath.
And any second that torrid piss would fill up his nappy completely.
There was a thin layer of sweat covering his forehead now, both from the effort of holding back the flood backing up in his urethra and from being so turned on that he was actually afraid he might have to come before he could piss properly because he was so damn hard.
And then the agonised, blissful seconds came to an end and led into the holy release.
Severus almost whined aloud when his muscles gave in and piss began stuttering and leaking out of his rock-hard cock, spreading all around his crotch and his arse, billowing up to bath his pubes, causing him to be a tad nervous about whether the nappy was thick enough to soak it all up or whether he would leak into his trousers after all.
But that thought was quickly drowned out (ha!) but the overwhelming sensation of his steadying stream and the hissing sound against the padding. His heart was beating hard enough for him to tremble and when he’d released enough piss to somewhat relieve his aching bladder, his cock was so hard that he had to touch himself.
Rubbing the soaked warm padding against his hard-on, he threw his head back, moaning and bucking against his own hand. Fuck, this is better than I thought it would be … He paused for a second, right before he passed the point of no return, to prolong this for a bit longer, then he began rubbing himself in earnest again, grunting and gasping through each firm stroke and pinch, savouring the sensation of his piss being squeezed out of the padding against his flesh again, all the while keeping his eyes firmly closed because seeing his classroom would completely ruin this moment for him.
And with a last borderline brutal push down the front of his crotch, Severus came, crying out his pleasure louder than he ever had, half-heartedly trying to stifle it with his fist pressed against his mouth, and shot another load of hot cum into the soaked padding of his nappy. His chair creaked over the stone floor when his legs stiffened, his balls constricting almost painfully, lust bolting through his body like a pinball.
He slumped into his chair groggily when his climax waned, panting pathetically but smiling, albeit blearily.
Bloody hell, that was glorious …
Keeping his eyes closed for a while longer he savoured the last twitches of his orgasm – and moaned again when his cock had deflated enough for the rest of his piss to finally leave his body. Fuck … Once again he was bathed in delicious almost scorching heat and hadn’t he come just now he would instantly grow hard again.
Probably was for the best to not try this before talking about it with Hermione … He wouldn’t have been able to keep his fingers off those nappies after experiencing this.
When his flow finally tapered off, Severus stood up gingerly, feeling his crotch and his backside but his trousers were dry. As it seemed, his charms had done their job and held all of his piss. The nappy didn’t even feel overly wet actually, only heavy and bulging between his legs and he found he liked that. Enough anyway to keep it like this until Hermione would visit him for lunch …
