It was late. Or early. Remus didn’t care to check the time. All he knew was that he would much rather be sleeping. Surely after seven years of sharing a living space with someone you’d think that he would be numb to this sort of thing. But here he was, lying on a bed in the Potter’s spare room listening to James and Lily go at it.
He couldn’t blame them really. It was the beginning of August and they hadn’t seen each other since they left Hogwarts. Really left Hogwarts in fact. Remus didn’t let himself think about how he would probably never return to the castle halls. If he did it wouldn’t be the same anyway.
James’ parents were on holiday for the week so James decided to invite the Marauders over to spend the week (not that his parents would have minded, they adored each and every one of them). Sirius was already living there full-time, Peter was on holiday with his family, and Lily was finally, finally back from visiting her grandparents. So it ended up being James, Sirius, Remus, and Lily. Not that Remus minded. He would have otherwise been sharing a room with Peter and he had had enough of hearing his snores to last a lifetime. It got to the point where James would secretly place a silencing charm around Peter’s bed the nights before early morning Quidditch practices.
So he couldn’t exactly blame James and Lily for wanting to make up for the lost time. But did they have to be so fucking loud? They were 18, they knew how to use silencing charms. James knew he was sharing a house with other people. That his room was sandwiched between Sirirus’ and the spare. Maybe this was why the Marauders called Remus a prude. He was a fan of sex, a big fan actually, but it seemed that having the opinion that one’s sex life should remain between those involved made him a prude.
Remus rolled over, pressing his face into his pillow. He was cursing James for being able to last this long but also a little proud of his improvements. Remus groaned. Now he wished that he was sharing a room with Peter. Maybe his snores would drown out the sounds from the other side of the wall.
The door to the spare room creaked open. Remus quickly turned his head to face the door. He could see a sliver of wand light making its way into the room and a mess of curly hair. “Moony? Are you awake?” Sirius.
His question was punctuated by a rather loud moan. Remus was severely uncomfortable. Lily was basically his sister, James his brother. It was like listening to his - Remus stopped himself from completing that thought. He did not need to be making the situation worse.
Sirius stepped into the room and closed the door behind him. “I’m not even going to let you answer that, I know for a fact that no one is sleeping through that.” He made his way over to the bed and sat down, pushing Remus to the far side of the bed.
Remus turned onto his side. “What are you doing here?” He tried to shield his eyes from the light emanating from Sirius’ wand.
“Shit, sorry, Nox.” The light went out. “I can’t sleep.”
Remus snorted. “And that’s my problem, because … ?”
Sirius spread himself out on the mattress. “My bed is against the same wall.” Remus didn’t see the issue. So was his. Sirius turned to face Remus. “Like, we share a wall. My bed, wall, his bed.” Ah. Remus could hear James’ bed bang against the wall every so often. He could only imagine how much worse it would be to be right there.
“So you’ve come to my room.”
“So I’ve come to your room.” With the little light that was escaping through the gaps in the curtains, Remus could make out Sirius’ grin.
“Hate to tell you, but it’s not much better over here.”
“It’s better than over there, believe me.” Remus did.
Sirius closed his eyes, and sighed, exhaling through his nose right into Remus’ face. Remus rolled over to face the other way and felt Sirius get under the covers with him.
Remus closed his eyes, willing himself to fall asleep. He hadn’t shared a bed with Sirius in years. He hadn’t shared a bed with anyone in years actually. It was weird. He could feel the presence of another body, the dip of the mattress. He could hear Sirius breathing. He could hear Lily and James. Remus groaned and tried to get more comfortable.
“Stop moving,” Sirius groaned.
“You’re in my bed, I’ll move if I want to move,” Remus quipped.
“Fiesty.”
“Shut up.”
Remus tried to sleep. He really did. He kept his eyes closed, he tried to go through the alphabet and think of the longest word that started and ended with the same letter, a trick that his mother taught him. Nothing worked. He wasn’t sure how long it had been, how many times he had heard “more” and “please” and “faster”. He adjusted himself again, and bumped into Sirius. He bumped into more Sirius than he was expecting. Remus froze.
“Are you … hard?”
Remus didn’t need Sirius to answer verbally. The question was rhetorical. He could feel the answer.
In fact, Sirius didn’t answer. Remus didn’t know what to do. Neither of them moved. Remus would be lying if he hadn’t thought about being in a situation like this with Sirius (minus his two other friends fucking in the background). He had stopped thinking about it when Sirius had started making plans about them living together after Hogwarts. He could not act on his feelings and have shit hit the fan leaving him with nowhere to live in the fall. He also couldn’t continue to sit on his feelings and be the loser who thirsted over his flatmate. He was already the loser who thirsted over his best friend.
But now. Now. Now.
Was Sirius hard because of hearing James and Lily? If Remus could separate the noises from who they came from then … it sort of was a little hot. And if he let James and Lily’s names slip in … it felt, sexy? Remus’ dick twitched.
Remus wanted to test the waters. Maybe Sirius was sleeping. That would make more sense. And also make Remus feel weird for getting turned on by this situation. Somehow Sirius also being turned on made it ok. Alright. He was going to do this.
Trying to make it seem as nonchalant as possible, as if he was simply readjusting his position on the bed, Remus moved his ass over the bulge in Sirius’ pyjamas. He was met with a quick, sharp, inhale. Remus did it again. This time it was the sound of a small moan, caught in the back of a throat. Remus paused for thought. And did it again.
This time, Sirius’ hand reached out and gripped tightly onto Remus’ hip. He could feel Sirius’ nails digging into his skin. “Remus,” Sirius said through his teeth. Remus moved his body closer, his back flush again Sirius’ chest.
“Yes?”
“What are you doing?”
“Just trying to get comfortable.” Remus demonstrated, grinding his ass into Sirius. Sirius’ grip tightened, Remus could hear the hitch in his breath. “Something wrong?” Remus was fully hard now. He peeled Sirius’ hand off and rolled over so they were face to face.
Remus pressed himself into Sirius, felt his clothed cock press over Sirius’. Sirius squeezed his eyes shut.
“Seems like someone got a little turned on listening to our friends, hm?” Remus teased, repeating his previous motion.
“Fuck off,” Sirius breathed.
“Ok, I’ll stop.” Remus stopped moving and was about to put some distance between them when Sirius reached out and gripped Remus’ waist.
“Don’t you fucking dare.”
Remus smirked and pressed himself closer to Sirius. They were touching everywhere but their heads. That was the one place Remus was unsure of. Sirius could be horny as hell but that didn’t mean he wanted to kiss Remus. He could work with that though.
Remus lifted his head off the pillow and brought his lips to Sirius’ ear. “Turn over.”
Sirius didn’t hesitate. In an instant, he was facing the other way and now it was Remus’ turn to hold him by the waist. Remus pulled him closer, pressed Sirius’ ass against his dick. He moaned at the pressure.
He could still hear James and Lily, it felt as if they were getting louder. Remus leaned his head into Sirius’ neck and began kissing it, moving up, and lightly bit on his earlobe. Sirius moaned, a real one this time. Remus reached his hand further and let it land on Sirius’ stomach. He slowly moved it lower, and slipped under Sirius’ waistband. He slid his hand over to the side, avoiding the head of Sirius’ upturned dick. Slowly, he ran his fingers over the base. Sirius hissed, breathing out a fuck. Remus lightly trailed his fingers up.
“Please,” Sirius begged as a voice in the other room screamed the same word.
Remus wrapped his hand around Sirius and began stroking. Sirius was big. He pulled his hand out of Sirius’ pyjamas and Sirius whined at the loss of contact. Remus loved the sound. He hooked a finger around Sirius’ waistband and began pulling. Sirius got the message and lifted his body off the mattress so Remus could pull the bottoms off. It was hard, having only one hand available, but eventually, they got to Sirius’ mid-thigh, exposing both his dick, and his ass. Remus lifted his hand closer to Sirius’ mouth. “Spit,” he commanded, directly into Sirius’ ear. Sirius did as he was told and spit into Remus’ hand.
“Good boy.” Remus praised, bringing his hand back to Sirius’ dick. With Sirius’ spit slicking up his own dick, Remus began stroking at a faster pace than before.
“Fuck, Moons.” Sirius moaned, pressing his ass into Remus. Remus groaned. Keeping one hand around Sirius, Remus used his other one to shimmy out of his own pyjama bottoms. It was a little awkward, and unlike Sirius, he was wearing underwear as well. Eventually, they were both at his ankles and he kicked them off, losing them in the sheets.
Returning to the task at hand, Remus pressed his now naked bottom half against Sirius. They both moaned as Remus’ dick pressed between Sirius’ cheeks. Remus began thrusting, grinding his dick against Sirius as he continued to move his hand around Sirius’ cock.
The sounds from the other room were beginning to lose their rhythm, there was more urgency. Sirius moaned. “Please, I need you.”
Remus tightened his grip around Sirius. “I don’t have any - I didn’t bring -”
Sirius cut him off “I know a spell,” He pushed himself out of Remus’ grip and searched for his wand on the bedside table. He muttered something under his breath and moaned. He returned to his position, back pressed against Remus. He reached behind him and took Remus’ hand, guiding it to his hole.
Hesitantly, Remus pressed a finger against Sirius and slowly eased in. To his surprise, it slid in. Whatever that spell was, Remus was glad that he didn’t have to curse himself for not bringing lube.
“Naughty, naughty.” Remus teased, pressing more of his finger in. Sirius moaned. “Who taught you that spell, hm? Or did you look it up yourself?” He spoke into Sirius’ ear. Sirius didn’t answer. Remus slowly started thrusting his finger. “You did, didn’t you?” He kept going. “Oh Pads, what am I to do with you?”
This time Sirius answered. “Anything.”
Remus tutted, “You have to be more specific, come on,” He added a second finger.
“Everything,” Sirius moaned.
Remus started scissoring his fingers, kissing along Sirius’ neck. “You really are a naughty boy, aren’t you? Letting me finger you while we listen to our friends fucking.”
Sirius groaned in response. Remus could tell he was getting impatient. He pulled his fingers out of Sirius and gripped his own dick. He gave it a few strokes. He was a little worried about going in dry, but he could tell from his fingers that Sirius’ insides were anything but.
He pressed the tip against Sirius’ hole. Teasing him just a little longer. The sounds from James’ room were definitely getting louder. Remus was surprised they were still going, but no longer complaining.
Remus pressed into Sirius and was met with warm, wet, heat. They both moaned at the feeling. Remus pressed himself all the way in. “Fuck, you’re huge,” Sirius moaned. Remus reached his hand around and wrapped it around Sirius. He ran his fingers up to the head and was met with a surprising amount of precum.
“Fuck,” Remus moaned, stroking Sirius, using the precum as lube. Remus slightly pulled out of Sirius and eased himself back in. He started to pick up the pace, matching his thrusts with his hand.
Sirius began chanting a slur of curses, filling in the gaps from their friends on the other side of the wall. Could they hear them? Were they getting off on hearing Remus and Sirius just as they were them? Fuck. Remus found that he actually enjoyed the thought. He let go of Sirius’ dick and grabbed his hip, turning him so he was chest first on the mattress. His head to the side, flushed cheeks highlighted by the light from the window.
With a leg on either side of Sirius, Remus began thrusting, finding that this position gave him more momentum. Sirius noticed it too. “Fuck, Remus!” He all but screamed. James and Lily heard that one for sure, but there wasn’t a pause.
Remus started moving faster, Sirius was loud. Remus loved it. He loved knowing that he was the one causing those sinful sounds to drip out of Sirius’ mouth.
Sirius reached out behind him, searching for Remus’ hand. Once found, he brought up to where his hair lay spread across the pillow. Remus understood immediately, grabbing a fistful. Sirius moaned and Remus pulled harder, causing Sirius’ head to lift from the pillow.
On the other side of their shared wall, Remus could hear the chanting of don’t stop and began picking up his own pace. With his free hand, he grabbed Sirius’ waist and pulled him up so he was on his hands and knees. Remus didn’t let go of Sirius’ waist or his hair. He started thrusting faster, harder. Sirius’ dick bounced with every thrust, still leaking.
“Touch me, please, fuck,” Sirius begged between moans. Remus obeyed and reached around and under Sirius and wrapped a hand around him.
“Fuck, I’m close,” Remus and James.
“Don’t fucking stop,” Sirius and Lily.
Remus started thrusting harder. “Fuck, right there, yes, yes, yes,” Sirius moaned.
Remus let go of Sirius’ hair and his head fell forward. Remus could feel himself getting close. “Fuck, I’m going to cum, please let me cum, please, please,” Sirius started begging. Remus didn’t remember telling Sirius to wait until he was told to cum but fuck if it wasn’t hot. Remus was about to tell Sirius yes when he got an idea.
“Wait until they do. So they can hear it.”
Sirius let his arms go limp and he faceplanted into the pillow. Face down, ass up. “Hnngg.”
Remus smirked, pounding harder into Sirius’ prostate.
And then, with a loud moan, a curse, and a final bang of the headboard against the wall, the sounds came to an end. That was all he needed.
Remus sped up his hand. “You can cum now.”
Sirius let go with a mix of swears in both English and French, coating the sheets of the Potter’s guest room with his cum. The feeling of Sirius clenching around him is what tipped Remus over the edge and he came deep, and hard inside Sirius.
Remus caught his breath and slowly pulled out. Sirius winced at the feeling before extending his legs and letting them flop on the mattress, utterly spent. Remus grabbed Sirius’ wand and quickly cleaned up the mess, knowing Sirius would probably not like to fall asleep sticky with both of their cum.
Remus let himself fall into the mattress beside Sirius.
“Maybe I should sneak in here more often if that’s what’s waiting for me,” Sirius chuckled.
Remus snorted. “You say that now.”
Sirius opened his eyes in confusion.
“You seem to have forgotten that the four of us will be eating breakfast together in the morning.”
There was a pause.
“… I did forget about that part.”
Remus laughed again and closed his eyes. Finally, silence.
