Work Text:
Sirius Black was losing his mind. He couldn't handle it anymore, he just couldn't. He'd been controlling himself all week, but today he just couldn't do it.
Remus Lupin, his best friend, had taken a liking to exercising on a near-daily basis. He's been going out on hikes and runs in the Forbidden Forest for a few weeks now. The Marauders, at first, teased him about it, asking if there was someone he was trying to impress. Remus would flip them off with a laugh and explain that it just made him feel more in control of his body and that 'there wasn't anyone to impress'. Sirius would always stiffen when he'd say that, acting shirty for at least fifteen minutes afterwards, much to James' chagrin.
The werewolf had always been on the scrawny side, with long limbs that were pale and littered with alternating light pink and silver scars. However, the consistent exercise had really made a difference, ask Sirius because he's had to stare at it from a distance for weeks. He had bigger, more toned arms and a more sculpted back now, almost like James' (from all the quidditch practice, of course). Frustratingly, Remus didn't seem to notice the impressive change in his body and continued to act like he was just a lanky, nerdy Prefect. Or maybe he had noticed and that was why it has been on display all the time. From swimming in the lake shirtless with the group (as it was now the beginning of summer) to openly changing in front of his dormmates, Remus didn't hide his body anymore. And, oh, he had those black shorts he’d wear on runs that made him look just delicious. Sirius always had to excuse himself to the common room whenever Remus would traipse around in them before finally leaving the dorm. Sirius was happy for the boy who had gotten over his age-old insecurity, really. Plus, Sirius supposed the newfound confidence that came with looking that hot helped.
Their dormitory creaked, dragging Sirius out of his thoughts. "Hello, boys," Lily Evans peeked through a little opening through the door. James jumped up from his lying position on Peter's bed and grinned at the redhead, fixing his glasses. Sirius rolled his eyes at his best friend.
"Evans! How can we help you?" Not 'What the hell are you doing here?', not 'Have you ever heard of knocking?', Sirius thought with a huff. James was so embarrassingly whipped.
"Oh, I'm just waiting for Remus, we're going for a walk by the Black Lake," Evans hummed, closing the door behind her and walking into the room slowly. She was wearing bootleg jeans and a dark green sweater that was at least three sizes bigger than she was and looked suspiciously like Remus'. Sirius narrowed his eyes at her. Evans then increased his level of annoyance when she judgmentally observed Sirius' messy side of the room near his four-poster bed and then politely smiled at him.
"He's in the bathroom, Evans, can't you wait outside?" Sirius spoke in a bored tone, rolling his eyes again and falling back on his bed. James gasped, scandalised.
"Padfoot, don't be rude!"
"Prongs, kiss my arse," Sirius shot back, dodging the pillow James threw at him. Peter snorted, disguising it as a cough when Lily turned to him with a raised eyebrow.
"Is-Is it, like, a date you two are going on?" James blurted out suddenly, pretending to not be distressed (he was failing). Sirius froze on top of his bed, then slowly sat up and turned to James with furrowed eyebrows. A date? Sirius hadn't thought of that. Remus wouldn't, Sirius was sure. This was James' future wife, basically. Yes, they were very close friends, but he knew that Remus would never. If so, then why was there an unpleasant feeling in his stomach and a strange tension in his jaw?
"What?" Evans raised an eyebrow at the bespectacled boy and then looked between him and Sirius, hand on hip.
"Is it a date?" James asked, adjusting his gold-rimmed glasses, this time his voice more steady. The expression he wore on his face looked like he was preparing himself to hear the worst news he could possibly hear.
"No! Merlin, no, Potter!" Lily laughed loudly, clutching her stomach. "Remus is just my friend!" Sirius frowned at her, though he couldn't deny the relief he felt.
"Alright, it's not that funny, Evans," he muttered, leaning back to relax against his pillows, hands behind his head. Lily looked at him with curiosity and mirth in her eyes, and her mouth opened to say something to the ebony-haired boy, but something caught all their attention.
Just then, Remus came out of the bathroom, cutting the redhead off. Sirius was secretly thankful for it; from the look on her face, Sirius suspected she'd say something he wouldn't like to hear or that he wouldn't like James and Peter to hear. Remus was wearing long, straight-legged muggle jeans and an adorable beige sweater, hair curled delightfully over his forehead, poofy from putting on his clothes. "Oh, hey Lils," he smiled at her in greeting as he walked over to the dresser. He bent over to open the sock drawer and Sirius bit his lip (he'd been doing that much too often these days) and looked away. "I'll just put on my shoes and we'll get going."
"Okay, Rem. Potter over here was just asking me if we were going on a date," she smirked, twirling her fiery hair absent-mindedly "Black thought so, too."
Sirius shot up again. "I never said that!"
"Really, Prongs?" Remus smirked as he turned to look at his best friend; Sirius could see the hidden message directed at James in those amber eyes; 'Really? I'd go on a date with your Lily?'. James' face was red and he wouldn't look at either Evans or Remus. When Remus realised James wasn't going to provide an answer, the werewolf raised an eyebrow at Sirius. "And you. Is that really what you thought, Pads?" Sirius had to fight off an embarrassed smile because the look Remus shot him had a different message; 'Is that what you thought even though I've told you I like blokes?'.
Yes, this is the other reason Sirius had been in shambles over his adorable, sweater-wearing, werewolf best friend. Remus had come to him a week ago, pushing aside the red curtains of his four-poster bed and crawling onto the foot of his bed. He had a slightly crazed glint in his eyes and his hands were shaking when he'd explained to Sirius that he had to tell someone or he'd go insane. When Sirius received the news of Remus' newly discovered sexuality, he felt like he was living a life-altering moment. He'd comforted him and reassured him he'd be accepted by the rest of the Marauders. They hugged and Sirius almost died from the way Remus wrapped his arms around his waist.
"Evans is bloody lying, I did not say that!" Sirius replied immediately, face heating up, pointing at Lily accusingly. Remus' almost predatory smile grew and his eyebrows rose high on his forehead as he stared at Sirius curiously. It felt like he figured out all his secrets, and Sirius suddenly felt exposed under the taller boy's gaze. He definitely didn't not like it.
"Whatever, Black," Evans rolled her emerald eyes and started to pull Remus out of the room. "Goodbye, now."
When the door was shut, identical sighs of relief escaped Sirius and James at the same time, and they both turned to each other with narrowed eyes when they'd realised. Peter shot them a weird look then got back to reading his quidditch magazine.
When Remus returned to the dormitory, he was a sight to behold. He had remnants of a smile still on his face, cheeks endearingly red and his hair became curlier from the humidity. When he set his shining cocoa-coloured eyes on Sirius —who was sitting on his bed cross-legged— his smile got even wider. "Hiya, Padfoot."
Sirius cursed inwardly at what this boy was doing to his stuttering heart. "Hi, Moony," he breathed out, grinning helplessly at his best friend. His eyes flicked all over Remus; from his flushed face and mirthful eyes to the slope of his waist and the way his thighs looked in his muggle jeans. Fuck.
James and Peter had gone to the library to find books they needed for research for a prank the Marauders were planning. Sirius, left alone a couple of hours, was trying to finish a quite difficult Potions essay that was due soon and when Remus walked in he was writing down the last sentence with his black-feathered quill. Sirius was thankful he was done with his homework and already sat on his bed because he had just about fainted when the werewolf started peeling off his clothes by his drawers, with his back to his friend, most probably to change into his pyjamas. In the middle of his changing, Remus stretched his hands in front of him, making his back muscles flex in a way that had Sirius practically salivating. Remus quickly turned to look at Sirius when a humilatingly high-pitched noise escaped the older boy from where he was sitting on his bed. Shit.
"...You all right, Padfoot?" with furrowed eyebrows, Remus' eyes were surveying him; Sirius could see them eyeing him from the other side of the dormitory.
"Er—Y-yeah, Moony," Sirius choked out, trying to face the other way to hide the inevitable redness in his face. "I'm fine."
"You're sure, love?" Remus came closer (still shirtless!), peeking at his best friend's red face. Sirius almost choked on his own spit at the pet name. "You look warm. And you've been...distracted."
Sirius froze on his bed; Remus had practically purred the last part. Surely, that wasn't flirting, was it? He could've been clearing his throat or something. When Sirius finally braved a glance up at his best friend, his theories were immediately debunked. Remus looked amused, a smug smirk plastered on his face. He shocked Sirius by placing his calloused hand on his forehead. "Oh, Pads. You're definitely hot," he mused, now fully amber eyes determinedly not leaving Sirius' wide, grey ones. The boy gingerly sat down next to Sirius, abnormally close; their shoulders and legs touching (He isn't wearing a shirt! Sirius thought once again).
"No, I'm— I'm fine. H-how was your walk with Evans?" Sirius stuttered, looking away from Remus. He hoped his cheeks weren't too red, especially after Remus' overt display of affection which Sirius seldom had the pleasure of experiencing.
"It was fine, but never mind that. What's up with you?" Remus insistently pushed on, trying to catch Sirius' gaze. "You can tell me anything, y'know that, Padfoot."
"Yes, Remus, I know."
"'Remus'," the werewolf repeated, with a raised eyebrow. "See, now I know for sure that something's going on," Remus cooed, rubbing up and down Sirius' arm tormentingly, the smallest uptick of his lips on his face. He then whispered near Sirius' ear in an unnecessarily low voice, "Tell me." That's it. Remus must know what he was doing. Sirius swore he could see a hint of amusement in the werewolf's eyes; he definitely knew what he was doing. Nevertheless, even with this incriminating knowledge, Sirius' face turned redder than ever, Remus' voice doing things to him.
"I-I don't.."
Remus watched Sirius with his big, chocolate brown eyes, patiently waiting for the older boy to formulate an answer. When he realised that Sirius’ fried brain wouldn’t be coming up with words a few moments later, Remus sighed disappointedly and got up to continue changing by the dresser. He slowly slipped off his pants almost tantalisingly and then put on his pyjama bottoms (very low on his hips). And to say that Sirius was fucked would be an understatement.
Before he knew it, Sirius’ legs had gotten him up from his bed and then he was roughly pushing Remus against the wooden dresser. A small gasp escaped Remus as his wide and impossibly deep brown eyes locked with Sirius’ stormy grey ones.
"You're killing me, Remus," Sirius hissed in his ear, tone half-desperate and half-angry. His hand gripped Remus’ waist like he was expecting the taller boy to attempt to leave.
"W-what?" Remus breathed out in a stutter, hands instinctively coming to hold the edge of the dresser to support his weight. The way he looked down at Sirius with such a mixture of shock and excitement and, Sirius hoped, desire made the Black groan in frustration.
"You and your shirts and your muggle trousers and those fucking black shorts," he breathed, closing his eyes for a moment and dropping his head back. When he looked back at Remus, the boy had a shit-eating grin on his face and his eyes glowed amber. "Godric, you know exactly what you're doing, don't you?"
"What am I doing, Pads?" Remus teased him mercilessly, twirling a strand of the boy's inky black hair around his finger. And fuck if that didn’t play with his feelings and his focus and the direction of his blood flow. Sirius’ grey eyes lost their fire for a second as his cheeks reddened.
"You-you—"
"Yes?" the werewolf whispered, smirk somehow still present. Remus then chose to take control of the situation, to Sirius’ utter delight, flipping them over to swap positions. Then, he grabbed the back of Sirius’ thighs and -honest to Godric- picked him up. When he’d sat Sirius on the dresser, the older boy was too flustered by the manhandling to do anything but gape at his best friend.
"Kiss me, Sirius."
It was as if his brain conveniently whirred back to power. Sirius leaned in fast, not hesitating for a second, and pressed his lips to Remus’ awaiting ones. Remus let out a maddening sigh and immediately opened his mouth for Sirius to explore. Sirius keened, licking into the other boy’s mouth, hands flying to the golden-brown curls like they’ve always wanted to, feverishly running his fingers through the soft locks. Remus' hands were strong and so there on Sirius' waist, pulling him even closer as he gave a little bite on the Black's lower lip and was rewarded with a breathy moan.
The only thought going through Sirius' head, other than the mantra of MoonyMoonyMoony, was fucking finally.
