Chapter Text
“Come on, where did he hide this? I thought it was supposed to be easy to find.” James whispered frantically to himself while searching the room, trying to leave everything he touched as it was when he entered the room.
He’d been in there for five minutes already and he was afraid someone was going to get back to the dorm soon. If he couldn’t find that stupid thing in the next five minutes, he would bolt out of here, prank be damned.
As he closed the drawer of one of the bedside tables, still empty handed, he heard the sound of someone climbing up the stairs. Fuck.
James started to madly run around the room to find a good hiding place, picking up his cloak from where he had left it on the ground and throwing it over his head as fast as he could when the door to the room flew open.
Fuck, he knew that prank idea was stupid, he had told Sirius it wasn’t worth how much trouble they’d get into if they got found snooping around his brother’s room, but Pads swore to distract him long enough that he’d have all the time he needed to find what they were looking for.
Stealing something from Regulus felt idiotic enough for James to no want to partake in the prank but he was nothing if not loyal to his friends and Padfoot had begged for his help, so he didn’t have a choice really. And he was sure that Sirius would respect his part of the deal, after all, how hard could it be to distract your own brother for a few minutes?
Apparently, pretty hard was the answer.
Regulus was standing a few feet away from him, locking the door with multiple spells (that James thought looked way too complicated for a dorm room), as he took his shoes and robes off neatly near his bed, the one closest to the door.
Well, here goes James’ chance to try and leave discreetly.
He wasn’t even sure he knew half the spells Regulus used on the door and even if he did, there was no way he would be able to counter them without the other boy noticing.
Now he had to wait until he decided to leave his room, which might not even be for a while. Dinner is still a couple of hours away after all.
Might as well get comfortable.
James decided to sit soundlessly on one of the beds, praying Merlin and Morgana both that Regulus couldn’t see the dent he made in the emerald green sheets.
Looking a bit more closely at the boy before him, he seemed a bit out of it. Flushed cheeks and a raspy breath as if he ran all the way here, his normally pristine Slytherin uniform a bit askew, looking around as if he was expecting someone to be there. Maybe he thought one of his dormmates was supposed to be here, but if that was the case, why did he lock the door so thoroughly?
There was a light in the boy’s eyes that James had never seen before, no matter how much time he spent staring at him from afar the past few years. Could you blame him? Regulus looked like he literally walked out of heaven, he made the basic Hogwarts uniform look like it was made by the most talented designer ever with how fitting it looked on him. His delicate hands that were always shining with the silver rings he wore so elegantly, his soft curly black hair that would make anyone want to run their fingers through it and who wouldn’t get lost in the magnificent grey of his eyes?
Okay, maybe James had a teeny tiny crush on Regulus, but nothing would ever happen between them. He was Sirius’ little brother and James couldn’t do that to a fellow marauder and... and his train of thoughts got lost when Regulus took his shirt off.
I mean, everyone takes their uniforms off when coming back to their dorms right? He was probably just going to put some casual outfit on, right?
James started to get ridiculously hot underneath his cloak despite the coldness from the dungeons, but there wasn’t anything he could do. Regulus, face still as flustered as he was when he came in, started to look frantically for something in his trunk, his pale muscular back facing a half panicked, half admiring James.
He was shorter and leaner than a lot of the people on the quidditch teams, which made him perfect for the seeker position, but one doesn’t become the best seeker in Hogwarts without training hard, and his body clearly showed that. He wasn’t ripped like some of the beaters he knew but his muscles were clearly defined, even if you would never know underneath all his clothes.
It was not the first time he ever saw Regulus without a shirt on, the training schedule making it pretty easy to cross path with the other teams in the changing room, but there was something in the way he looked here, in the comfort of his own dorm, alone, that made James’ breathing harder to control.
He had all the space to watch him here, to appreciate every detail of every muscle in his back, the goosebumps starting to form on his skin from the low temperature in the rest of the room. It was way hotter than the tiny glimpses of skin he would peek at discreetly in the locker room.
Regulus grabbed a small glass vial full of some transparent liquid James didn’t identify right away, not that it particularly mattered to him. With a front row seat to a view like that, Regulus could start juggling knifes for all he cared, and James would still be unable to tear his eyes away from the other boy’s bare skin.
He placed the unopened bottle on his bedside table, the same one James was rummaging through just a few minutes earlier, before sitting down on his bed, his back against the headboard, unknowingly facing James.
Was he going to stay shirtless? Oh, this entire thing had just become ten times more fun, he’d have to thank Sirius later for his dumb prank idea (though, now that he was thinking about it, that might not be something he should share with his best friend).
The younger boy seemed a bit anxious, still looking around the room before stopping his gaze so close to where James was, as if he was seeing right through the cloak. Could he actually see him somehow? No, that wasn’t possible, he must just be looking ahead of him, and it just so happened that this was where James was sitting.
The younger man took a deep breath, looking determined, as he grabbed with slightly shaking hands at the seam of his open trousers (when had he opened them?) and got both his pants and briefs off in one swoop, before putting them neatly on the floor and sitting back down. James gasped as softly as possible at the sight, his mouth dropping open in shock and awe.
Of course, having a crush on Regulus meant that James had imagine what having sex with him would be like. He was a healthy eighteen-year-old boy, sue him for having wants and needs and a perfectly functional imagination.
Most of the time, in his daydreams, it would start slowly, building up from a few kisses to fully making out to undressing the other slowly before making love to one another (yes, James was a hopeless romantic, even in his own fantasies).
Of course, sometimes, late at night behind the closed curtains of his bed, he thought about situations a bit less romantic, a bit more savage. Pinning him against the wall of a supply closet, licking a trail from his mouth to his neck, marking him for everyone to see, getting on his knees for him, you get the picture.
But never in his wildest dreams had he ever thought a scene like that possible.
Regulus was lying on his bed now, completely naked, his head slightly raised from his pillow, his fully hard dick completely on show for James as he lazily started to stroke it.
He hissed as the coldness of his rings making contact with the hotness of his skin. The sight was mesmerizing, the silver-cladded hand slowly moving up and down in a rhythmic movement as James tried to keep his breathing as steady and silent as humanly possible.
From where he was sitting, he could see everything. The slight hitch in his breath, the flushing that gradually conquered more and more of his body, the expression of pure delight on his face, it looked perfect, he looked perfect. Like one of those ancient greek gods statues he’d seen once in a muggle museum. Regulus’ body deserved to be worshipped, he deserved a spot in a museum next to all the other art pieces.
Almost immediately (give or take the few seconds his brain short-circuited at the sight), two voices started battling in the older boy’s head;
one saying that he had no right to witness such a private moment, that Regulus deserved his privacy and that James should do something to get out of this situation (this was the voice of reason).
Another one telling him that Regulus would never know, that he could keep this a secret and just think of it as a fantasy come true, something that could’ve come from his imagination and no one needed to know it ever happened (this was the voice of horniness).
His first reflex was to listen to the voice of reason; James prided himself in being nothing but a gentleman after all, and watching someone masturbate while they weren’t aware of it was the exact opposite of that.
He closed his eyes, fully intending on not opening them until he was sure this was over, concentrating on his breathing to try to calm his rapidly thickening dick from getting even harder. He wasn’t going to get an erection right now, he refused. This whole think felt like betraying Regulus’ trust, and he wasn’t about to ruin any chance he might have at having any sort of relationship with him.
Breathing in. Breathing out. Breathing in. Breathing out.
The younger man’s pantings made James feel overwhelmed but he had no choice. He wasn’t about to give in to his longing just like that. He was stronger than that.
Breathing in. Breathing out. Breathing in. Breathing out.
There was a small break in movement, the sound of Regulus’ hand stopping and James was almost... disappointed? Until he heard the noise of a vial opening. And the almost silent sounds of the slytheryn’s hand on his cock changed into obscene wet noises as his moaning became louder and louder. The gryffindor’s breath hitched in his throat at the new noises. He wasn’t going to look. He wasn’t. He went back to focusing on his breathing.
Breathing in. Breathing out. Breathing in. Breath-
“Oh putain” whimpered Regulus under his breath, making the other boy shiver with his entire body despite the oven-like temperature under his cloak. “Oui, encore, plus vite.”
With his eyes closed, James felt as though he somehow had enhanced hearing. He could hear each and every one of the small noises, the wet sounds of the boy’s hand stroking his member, his shivering pants, his little moans and most of all, the French words he moaned under his breath that made something inside of James snap.
Fuck being a gentleman. Fuck the voice of reason, that voice didn’t have the biggest hard-on of its’ life while in front of its’ biggest fantasy ever.
James opened his eyes again, startled to see how much more debauched the boy looked with his half-lidded eyes that seemed to somehow still stare right at him, his left hand wet with the same liquid from the vial, now standing open on his nightstand (lube, he realized with bated breath) frantically tugging at his cock while his right hand tightened in the silk green sheets beneath him, his back arching slightly off the mattress.
His entire body seemed to be shining, his pale skin coated in a thin layer of sweat. It took everything in James to not get up and lick it off his body like a man dying of thirst in front of an oasis.
The last bit of sanity he was hanging onto finally ruptured as the zipper of his trousers flew open, not even aware of the noise he shouldn’t be making, and finally, after what feels like hours (even though it couldn’t have been more than a few minutes), he pulled his hard dick out, leaking precum everywhere inside the scorching heat of his cloak.
The entire scene felt so strange to him, touching himself secretly to the man of his dreams, naked on his bed, but something about the entire situation excited him way more than any porn magazines or late-night thoughts ever did.
And the noises, oh the noises. James was dying to be the one to make Regulus sound like that. To be the one he spoke french to. To be the name he would moan as he came.
“Oui, encore, vas-y plus fort” Regulus cried out needily, his rhythm completely erratic, slowly coming undone right in front of James’ eyes.
The older boy, completely captivated by the display in front of him, started matching the crazy rhythm the slytherin was imposing to his body, doing his very best to bite back his own moans.
This entire situation was way too intoxicating. He felt as though he was dreaming and would wake up any moment now. But it was real, he was going to come right here under his cloak on some slytherin’s bed while watching his best friend’s little brother having the time of his life.
It should’ve felt wrong, he should’ve been disgusted with himself, he should’ve stopped. But he couldn’t, and more than that, he didn’t want to.
As he started to feel the pulsing of his cock in his hand getting increasingly powerful, James couldn’t help but imagine of what Regulus would think if he knew. Would he think of him as a dirty pervert? Would he yell at him and hex him? Would he find all of this as hot as James did? Oh Merlin, he hoped he’d love it as much as James was loving it right now.
“Oh mon dieu, I love this, don’t stop, s’il te plaît ! Encore! Je t’aime.” His entire body shaking, white ropes of cum flying on his beautiful hand and torso as he moaned an incoherent mix of french and english. His eyes, still gazing over the bed James was sitting on, finally closing in a wave of pleasure.
Whoever he was imagining, James could tell that he was definitely passionate about them. It was easy for him to think of these words being directed at him. All this passion and his frenetic cries made James finally come undone. He could feel the hot slick release shooting out of him directly in the sheets below him.
All he could hear was his own panting over the rushing of blood in his ears. Regulus was still caressing himself gently, coming down from his own orgasm, murmuring something again and again to himself with a huge smile on his face.
“James” he breathed, this time a bit louder. His eyes opening back, trailing in his direction, the younger boy smiled some more, as if he could see him under his cloak.
At this, James stopped breathing entirely, not sure if he heard it right. He knew he couldn’t have been that discreet in the last couple of minutes, but he thought the other boy would have been too wrapped up in his own high that he wouldn’t have noticed how much noise he made.
He’d never seen Regulus looking so at ease, so relaxed, so happy. Did he know James was here or was it just a coincidence? He certainly would have been more upset if he knew, right?
Maybe he’d heard wrong. Maybe he was thinking of someone else named James (though that was his least favorite option). While James was busy overthinking the last few minutes of his life, Regulus slowly got up, his movements still a bit slurred, grabbed some clean clothes and started walking towards the bathroom before looking once again towards the bed the gryffindor occupied, unlocking the dorm door with a smirk, and getting in the bathroom before turning the shower on.
Without thinking more about anyof this, James leaped to his feet, took the time to sort out his trousers and bolted out of the room as fast as he could underneath the cloak. He didn’t even take the time to think about the puddle of cum he left in some poor bloke’s bed, all he could think about was getting out of here as fast as possible.
As he was making a beeline from the slytherin common room, he bumped into Sirius who was visibly waiting for him. Both men stubbled on the ground, the cloak falling from James’ head.
“Oh, thank god you’re okay!” he said as dramatically as ever, hugging him on the ground while James grabbed his cloak off the floor.
“The little shit knew something was suspicious about me wanting to hang out with him, so he put some veritaserum in my tea!” he half-yelled, getting up to his feet and helping James do the same.
“Can you believe it? When he learned that you were in his room, he ran out so fast I was sure he was gonna kill you! Did he try to hurt you, Prongs?”
James was pretty sure his brain had fried sometimes between getting in Regulus’ dorm and getting out of it.
Regulus knew he was there.
Regulus knew where he was the entire time.
Regulus knew and he still did all of this.
He checked the outside of his cloak, the side that was supposed to be invisible. Right there, in the middle of it was a smudge of dirt. Not enough to make most people suspicious but if you knew what to look for, you’d definitely see it. The little shit indeed. He knew what he was doing all along.
On the way back to Gryffindor Tower, Sirius couldn’t help but notice the weird grin on his best friend’s face and hope it didn’t have anything to do with his brother.
