Chapter Text

Lily’s moan sent a shockwave down Regulus’ spine straight to his cock. He pulled the door to Lily and James’ room shut, flipping the lock with shaking fingers. He took a shuddering breath, almost not daring to turn around in case the dream he was currently living in dissipated. 

“Regulus.” James’ voice was low and ragged, drenched with desire. Regulus turned slowly to face the couple, his eyes greedily scanning their conjoined bodies, catching on James’ hand gripping Lily’s arse, then to her trailing hands as they ran up James’ chest, reaching around his neck and pulling him down so he could plant kisses along her clavicle. 

Cautiously, Regulus let his gaze find theirs, his eyes flitting between Lily and James, who were both staring at him, eyes blown wide with want. Want for him? He resisted the urge to pinch himself. 

He watched with bated breath, as Lily and James worked in tandem to rid James of his clothes. Lily grabbed the waistband of his pants and pulled straight down, just as James pulled his shirt off over his head. In one fell swoop, James went from being fully clothed, to naked as a Grecian God carved from marble. 

Regulus felt his cheeks heat immediately as he got a better look at James’ cock. Regulus suddenly knew where James got his seemingly limitless confidence. He was long and thick, proudly on display with nary a pubic hair in sight. Regulus had to close his mouth, unsure how long it had been open, as he watched Lily’s hand wrap around her boyfriend’s cock and give it a slow, tight tug. 

James moaned and Regulus’ eyes snapped up to meet James’. His eyes were half hooded, the golden brown of his irises gone completely, his pupils blown wide. His chest was heaving slightly, and Regulus could see the puffs of air leave James in short gasps as Lily continued to pump his cock as it rose quickly to full attention. 

James, holding Regulus’ gaze, bent down and licked a long strip of skin from the top of Lily’s chest to right behind her ear, nibbling on her earlobe. Regulus swallowed loudly, his recently spent cock making an impressive effort at getting hard again. 

Regulus wanted so badly to pull his belt off and fist his own cock, but he didn’t know if that would be polite. Was what had happened on the piano the extent of his participation? Was he just here to watch? The couple, in their bare skin and close embrace, felt a million miles away from Regulus in that moment, and he started to feel like he was intruding. 

James turned his attention back to his girlfriend, capturing Lily’s lips in a deep kiss. Regulus started to fidget, looking for some way to release the tension in his body, and reached around behind him, searching for the doorknob. If he was quiet, he could probably sneak out without them even knowing, grateful for the experience and happy to have played a role in their foreplay. 

His hand had just found the cool metal of the door knob when James’ voice broke through his anxious mental chatter. “I can taste you on her,” he growled. Regulus stared dumbfounded at the couple, eyes fixed at the point where their mouths met, one hand still clutching the doorknob. Regulus watched as James’ tongue explored every inch of Lily’s mouth, sucking and licking in a way that was borderline obscene. After a torturous minute, James pulled back and turned towards Regulus, licking his lips sinfully. 

“Liar.” Regulus scoffed, his eyes locked on James’s lips, which were a deeper shade of pink and much puffier than they had been at the piano. 

“Oh, you think so?” James pulled back and chided, “Want to bet?” He strode forwards towards Regulus, his fully hard dick swinging between his legs, and it took every ounce of self-control Regulus had to keep James’ eye contact. 

“I don’t think that’s a claim so easily judged.” Regulus nearly whispered, his vocal cords failing him as the appendage in his peripheral vision bobbed, splitting his focus. James was fully in his space now, not yet touching, but close enough to block out the ambient light emitting from the candles across the room on the bedside table. 

“Well, top-of-your-year Regulus Black, you love a good test, don’t you? Let’s give it a try, shall we? I’ve just marked Lily’s neck, why don’t you lick it and tell me if you can taste me?” James was so close Regulus could feel James’ breath on his cheek, and it was causing a now painful stretch in his trousers. Lily had followed James off the bed and was standing slightly behind him, arms crossed in a way that pushed her breasts together and created a long, delicious line of cleavage.  

“Alright, you’re on,” Regulus said with more confidence than he felt, and brushed past James with his shoulder, reaching out to wrap his hands around Lily’s now familiar waist and attach his lips to her throat. Lily let out a giggle of delight as Regulus licked long swipes from the dip in her collarbone up to the soft spot behind her ear that made her squirm. 

Regulus sucked languidly, knowing that James was watching, and savoring the moment beyond reasonable expectations for their bet. Somehow, this was comfortable. Their brief engagement in the parlor had given Regulus enough familiarity with Lily that he could relax in her arms. James on the other hand, was still an unknown, and his heart raced at what discovering James might be. 

“Well?” James interjected after a few minutes, “Can you taste me?” 

Regulus smiled into Lily’s neck at James’ impatience and dug his teeth further into her throat, sucking the skin there further into his mouth and marking her as his own, though she was someone else’s girlfriend. Lily gripped his curls tighter in response, causing a pleasant pain that kept him locked on her. When he finally pulled back, Lily let out a whimper that Regulus relished.

 “Well James, seeing as I haven’t tasted you yet, I don’t really have a frame of reference-” the rest of his sentence was cut off by James striding right up to Regulus, gripping his hair roughly and pulling Regulus’ mouth against his own. 

Regulus moaned and melted against James’ touch. The fire that ignited when their lips met rippled through Regulus’ entire being, setting his body alight and torching his soul. Regulus’ hands immediately sought out James’ body, running up and down all the parts of him that he could reach. He was hard and warm under Regulus’ touch, his skin was exceptionally smooth and he could feel every chiseled edge of his chaser’s frame. The anxiety that Regulus had been feeling about this moment was now completely obliterated and Regulus couldn’t get enough. Channeling his newfound confidence, Regulus reached for both James’ neck and his arse at the same time, pulling him closer, desperate to know every inch of James’ body. 

Firm. That’s all Regulus’ sex-addled brain could come up with. James was firm. Regulus’ mind briefly wandered to what it would feel like to have James on top of him, pressing every hard line of his body into Regulus’. He wanted it, wanted to shed every obstacle of clothing between them and fuse as one. He wanted to be so close that he’d be flattened into the mattress, gasping for breath but refusing to drag his mouth from James’. Regulus figured it would be a fine way to go, crushed to death by this beautiful boy. 

Regulus’ mind was brought back to the present moment with the overwhelming pleasure of a strong hand that wasn’t his own, grasping for his cock. Regulus broke the kiss, startled, and looked down, gasping at the sight of James palming at him through his trousers. 

“Take them off,” Regulus almost whimpered. His cock was now unbearably hard as he unconsciously thrust into James’ hand, desperate for more friction. 

“Needy one, aren’t you?” James said with a smirk. He didn’t move from where he was fondling Regulus over his clothes, teasing him mercilessly. Regulus bent his legs slightly, forcing James’ hand to brush over his belt buckle. 

“Off. Nowww.” Regulus slurred, dropping his hands from where they had been gripping James, but as he reached for his belt James caught both his wrists with one strong hand. Regulus looked back up at James, eyes wide with surprise and frustration at still being clothed as James lifted his hands over Regulus’ head and walked them back several steps to the door, where James pinned him. 

“Now now,” James chided, a wide sneer stretching across his cheeks, throwing Regulus’ refusal to let Lily undress herself back in his face. “Pretty sure what’s in there is a gift for me. Wouldn’t be very nice of you to open it yourself, would it?” 

Regulus swallowed, and he noticed James’ eyes track the bob in his throat, eyes lingering before bringing them back to meet Regulus’. 

Silence and desire hung in the air between them, Regulus having been struck dumb by the sudden turn of events, and retaining very little attention span for anything other than his aching cock. 

“I asked you a question, Reggie,” James’ tongue darted out to wet his lips and Regulus stared at it. “Not very nice of you to open my present for me is it?” James’ tone had dropped low but it was still playful, like Regulus could hear the grin in it. It was unfairly sexy. He shook his head, desperate to appease James, anything to get his hands back on Regulus’ cock. 

“Words, love, use your words.”

Regulus went slightly limp in James’ grip. One pet name and James Potter had turned him to absolute mush. He felt his face flame in the realization, embarrassment written all over it that had nothing to do with his current state of debauchery. 

“It would be akin to filling the third-floor corridor with water from the lake in the middle of exams with a sticking charm so potent that even Flitwick needed six hours to get it completely cleared out,” Regulus said resolutely, and watched with glee as James fought to keep his serious demeanor intact. A giggle erupted from the bed but Regulus kept his eyes on James, staring up into his eyes, daring him to break first. 

“No, that wouldn’t be very nice. Especially during my O.W.L. year, James! I think you should apologize to Regulus here, for interrupting his very important exams and teasing the poor bastard within an inch of his life.” 

Although he couldn’t see her, as she was completely obstructed from view by James’ massive frame, he knew she had pressed herself against James’ back as her hands snuck around his middle, dusting featherlight touches across his torso. Regulus’ eyes were still locked with James but in his peripheral vision, he could see James’ abs contract involuntarily. 

“What are you doing with your hands there, Evans?” James tutted, trying valiantly to appear unaffected, but Regulus could see his resolve slipping. He knew how low her hand had strayed when James’ eyes rolled back in his head. Regulus, proud to have not been the first one to break their eye contact, immediately looked down to see Lily lightly dragging one finger up and down the underside of James’ cock. 

“Oh you want to play, do you?” James growled and Lily squealed as he grabbed her wrist with the hand that wasn’t holding Regulus and spun her around so she landed on the wall next to Regulus. He hadn’t even noticed James also grab her other hand, it was so masterfully done. 

James was breathing heavily as he looked down at Lily and Regulus, in identical compromising positions, hands twisted above their heads, locked into place by James’ considerable strength. Regulus couldn’t help but look at her next to him, her chest bare and the breasts he had recently become obsessed with pushed out and perky, her tight nipples so close he could almost reach down and latch on. 

His head was just beginning to lower, desperate to reach out and suck, but his attention was brought back when James cleared his throat. 

“You two are insatiable. Just what am I going to do with the pair of you?” 

Regulus glanced over at her and she shrugged her head slowly, a wide smile forming on her face. 

“You love a tease, don’t you, Lily? And it looks like our friend Regulus here might do as well.” He smirked down at the pair of them. “So what will it be? Are you a tease, or are you going to put that pretty little mouth of yours to use?

Lily’s tongue darted out to wet her lips, reflexively, Regulus suspected. James took a breath, looking his girlfriend up and down. She squirmed under his stare and Regulus could smell the faintest scent of musk that he had become all too familiar with on the piano. He grinned, wishing he could reach out and feel between her legs, wanting to know just how wet she was. 

James turned his attention now on Regulus, giving him the same once over, dragging his eyes down Regulus’ still mostly clothed body. Under James’ gaze, however, he felt completely exposed. 

“I think he asked for you to take his trousers off, James.”  

“Practically begged,” Regulus added under his breath. 

James glared at them for a moment before responding.

“Hmm, I’m not sure, I don’t recall.” James took a step back, releasing his grip on both of them. Regulus’ arms dropped and he groaned at the sudden change in position. “You can keep talking if you like.” James kept walking backward towards the bed, Regulus and Lily in tow,  like a pair of moths to a very hot flame. “Or, you could beg some more.” 

The bed hit the back of James’ knees and he dropped himself onto it, spreading his legs wide, putting himself completely on display for them. His hard cock bounced slightly with the movement, and Regulus could see a drop of precum glistening at the tip. His mouth watered, but he hesitated, unsure how to make his move. 

He watched, transfixed, as Lily leaned forward, bending at the waist, and giving Regulus a phenomenal view of her ass in the process. She placed her hands on each of James’ thighs and moved in to brush her lips against his. Regulus watched her mouth, and heard a whispered “I love you.” James smiled as he looked up at her, and Regulus felt his heart constrict slightly as he watched James mouth the words back to her. Regulus was suddenly glad for his relative state of dress, feeling, once again, like he was witnessing something that wasn’t meant for his eyes. 

Lily slowly turned around to face Regulus. She knelt between James’ legs, and without breaking eye contact, found James’ dick and tugged at it. Regulus’ knees nearly buckled at the groan that James’ emitted as he dropped his head back and slapped the bed next to him. 

“Fuck.” Regulus’ eyes darted up to James, who had his eyes closed and his lower lip between his teeth. His abs rippled as he panted in time with Lily’s confident strokes. 

“James was so good earlier while you and I were playing, wasn’t he, Regulus? Serenading us with that song, it was so sweet was it not?” Regulus swallowed and nodded, transfixed by how large James’ cock looked in Lily’s hands. She could barely wrap one hand completely around its girth. 

“And he deserves a reward for that, don’t you think?” Regulus looked back at Lily, who had moved her free hand down her front and it disappeared between her legs. Regulus bit the inside of his cheek as he watched Lily play with herself and James at the same time. He nodded once more. 

“And it was such a kind thing that he deserves something a little special, no? Maybe, oh I don’t know, double the reward?” Lily smirked as she not so subtly scooted over so that there was room next to her between James’ legs. Did she expect him to sit there with her? “What do you say, Regulus? Will you help me give James a special reward?” 

Regulus watched transfixed as she removed her fingers from her cunt and held them out, glistening with her juices. She motioned with them, calling him forward, and it snapped him out of his daze, hesitancy falling away. 

He leapt forward like a man starved and immediately pulled her fingers into his mouth, using his tongue to wrap around and between the digits, sucking every drop of tart essence from them. Lily giggled and James groaned again. 

“I like it when you’re eager. So happy to please aren’t you, love?” Regulus nodded, biting down slightly on her fingertips. “And you’re so good with your tongue. Baby, you need to feel this. Regulus, will you show James how good you are with your tongue?” 

Regulus lifted off her fingers with a pop. He licked his lips, enjoying the way the question lingered in the air and James’ look of desperation as he waited for Regulus’ response. 

“I don’t know if my tongue is enough for James,” Regulus said playfully, quickly falling back into cheeky banter in the high of James’ sinful noises. 

“It is, it is. Please, Reggie,” James whimpered from the bed, barely audible between gasps of air as Lily continued to stroke him. 

“I think,” Regulus continued, eyes on Lily’s. Her eyebrow quirked, gleefully. “It might be better if we worked together as a team.” They both turned their eyes on James who smacked the side of the bed again, his hips writhing under Lily’s grip.

“Please, Merlin, I need,” he panted, his gaze flicking between Lily and Regulus. Regulus watched James’ eyes go wide as he and Lily leaned forward at the same time. Lily moved her hand to hold the base of his cock as they stuck out their tongues and licked long stripes up James’ cock in tandem.  

The moan that James emitted was loud and long, and Regulus had never heard a sound more beautiful. He surged forward again, desperate to continue to pull those filthy noises from him. Regulus and Lily worked together, lapping at James’ cock, making sure to cover every square centimeter of velvet skin with wet, open-mouthed kisses. 

James moaned and whined with abandon. Regulus watched him close his eyes in pleasure, only to snap them back open and gaze down at them, his girlfriend and his best friends’ brother, both on their knees between his legs, working together to suck his cock. 

Regulus needed more. He looked over at Lily, a pleading look in his eye. She understood immediately and smiled, pulling back from James’ cock and giving Regulus full access. 

He hesitated, breath caught in his throat, staring at the hard dick in front of him, slick with his and Lily’s saliva, and weeping for attention. He didn’t realize he had frozen when he felt the lightest touch on his chin and allowed James to pull his gaze up slightly so they could lock eyes. The touch was so tender, surprisingly so for how lewd the moment before had been. 

“Whatever you can take, baby. If it gets to be too much we can stop, alright?” His voice was soft, a low rumble that Regulus could feel in his chest. Regulus relaxed into the moment, never expecting to feel so comfortable with James, let alone while sitting in front of him with his mouth open and reaching for his hard cock. Regulus smiled and nodded, gently at first, and then smirked quickly before confidently taking James’ cock in his hand and leaning forward, swallowing his entire length in one go. 

James let out a strangled cry and Lily gasped. Regulus’s heart fluttered proudly as he wrapped his lips around James and sucked. Large, strong hands were suddenly in his hair, lightly gripping at his onyx curls and Regulus preened. He pulled back, keeping a tight seal with his lips, and dragging his tongue up the underside of James’ cock. He reached the tip and sucked in a breath, breathing out through his nose, and playing with the ridges of James’ head with his tongue. 

James stared down at him, disbelief written clear across his features. Regulus didn’t know if it was because of who was sucking his cock, or how. 

Regulus finally pulled off his cock with an erotic pop and licked his lips. 

“Fucking hell, Regulus,” James could hardly get the words out. His hips lifted slightly, not so subtly suggesting Regulus continue with his ministrations. “Where did you…” His voice trailed off.

“Just because I haven’t sucked your cock before doesn’t mean I’ve never sucked a cock before.” 

James laughed out loud and Regulus took pity on the weeping cock, stroking it confidently as he caught his breath. 

“No, that much is clear.” James chortled. “But that’s not just any cocksucking Regulus, that was…” James blushed furiously as he struggled to finish his sentence. 

“Well you know me, I’m a thorough student.” James’ eyebrows squeezed together in confusion. “And let’s just say there’s a lot of learning to be done when they assign three queer guys together in one dorm room.” James let out another groan and Regulus felt just the slightest of pushes on the back of his head. James’ willpower was failing him as he tugged lightly on Regulus, but he remained respectful. Regulus liked that. 

“So what? Were you, Crouch, and Rosier all just fucking each other?” Lily asked and Regulus looked over at her, her cheeks were pink and her eyes were wide. Regulus didn’t fail to notice that one hand was back between her thighs, the other fondling her breasts and pinching at her nipple. 

“Occasionally, sure. Barty and I figured it out first, so we were fucking a long time before Evan got involved. Eventually, Evan came out to us and we all played together a bit but those two idiots developed feelings for each other, and instead of admitting it and getting together, they preferred to ignore them and,” Regulus paused, blushing scarlet, “basically passed me back and forth.” 

Lily looked up at James with glee, dirty images clearly painted behind her eyes. James returned the look, dumbfounded and slack-jawed. 

“There were never any feelings there for me, which made it easier, you know? There’s a lot more you’ll try if you’re not worried about also managing a romantic relationship at the same time. Barty is a bit of a freak and there’s not much I wouldn’t give a go. I’ll just say we used our free periods wisely.”

“No way,” James chuckled. “You’re lying, I was in a dorm with mostly queer dudes too and we never got up to anything like that!” James exclaimed.

“Oh, never was it?” Lily inserted with a chastising voice. 

“Well,” James smirked, eyes rolling back in memory, “maybe once-” 

“Nope, you lived with my brother, I do not want to hear it.” Regulus cut him off, using one of his hands to cover an ear. Lily giggled and he felt her hand on his thigh, sliding up his leg and brushing lightly over his clothed cock again.

Fucking Merlin, these two would be the death of him. 

Regulus smiled at her before lowering himself back down on James’ cock, desperate for another taste. 

“Fuck,” James exclaimed, “such a good fucking boy.” Regulus loved that and rewarded James by humming, sending vibrations down the length of his dick. “Merlin Lily, he’s so fucking good,” James exclaimed as Regulus continued to suck his cock. 

He looked up at James through long eyelashes and devoured the sight before him. Glasses askew, curls mussed, sweat beading and starting to drip down his chest, James was the personification of lust and Regulus couldn’t get enough.

He worked his hands in tandem with his mouth, using both hands to grip the exposed skin as his tongue worked the tip, lightly twisting his wrists in opposite directions to maximize sensation. He weighed the significance of this moment in his mind. Here he was, with James Potter’s cock down his throat as the most beautiful man in the world thrust up into him. He wanted nothing more than to live the rest of his days with his mouth stuffed full of James Potter. 

Regulus could hear James’ breathing pattern change, as his moans came quicker and his pants more shallow. He knew James was reaching the edge and Regulus was, quite literally, gagging for it. He brought one hand down to tug lightly at James’ balls and in that instant James let out a particularly loud grunt and Regulus felt hot, sticky cum shoot down the back of his throat. The noises that cascaded out of James’ mouth as he continued to thrust lightly, riding out his orgasm, were fucking erotic. 

Regulus had been so thoroughly edged that the combination of the sight of James’ orgasm, the sensation of cum filling his mouth, and Lily’s playful strokes against his groin tipped Regulus over the edge, and he came hard into his trousers. He pulled off James’ dick, swallowing loudly and gasping for air as he rode out his own crest of pleasure. Black spots dotted his eyesight and Regulus lost all sense of time and space as he let the waves of bliss ricochet through him. 

Regulus didn’t know how much time had passed when he felt a soft hand on his back, rubbing calming circles into it. He smiled, at peace knowing Lily was nearby and looking after him. He blinked slowly, just now realizing his eyes had been closed, and found that his head was resting on James’ thigh. He looked upwards at James, whose eyes were clear and warm, with a hint of concern edged to them. 

“You alright down there, starlight?” Regulus purred inwardly at the nickname. Usually, he hated when people would call attention to his family’s particular habit of constellation namesakes, but coming out of James Potter it was the highest of compliments. 

“Fucking fantastic.” He sighed, not at all sarcastically. “I haven’t come in my pants since I was a fourth year. Not exactly how I saw tonight finishing.” 

James leaned down and captured Regulus’ face in both his hands, bringing his attention forward and nodding backward, signaling for Regulus to get up and onto the bed with him. Regulus did so willingly, albeit not so gracefully, as his legs felt a bit like jelly. 

James guided them both backward so they were lying on the bed, James with his thighs spread, and Regulus settling between them and on top of James’ chest. His hands ran delicately up and down the sides of James’ ribcage, basking in the euphoric feeling of just being close to James, being able to touch him like this. It was more than he ever dreamed possible. 

“First of all, you’re a stronger man than me, ‘cause I think I was still getting off in my pants till year six. Evans’ fault, obviously.” 

“You were just so easy to toy with James, how could I resist?” Lily’s voice was close as she made her way onto the bed and settled into the crook of James’ arm, bringing one arm up and around to rest again on Regulus’ back. Regulus heard the light suction sound of a kiss being planted and looked up to see James peppering kisses across Lily’s forehead. 

“And second of all,” James pulled his lips away from Lily to look down at Regulus, the blacks of his eyes wide. “Who said tonight was finished?” 

Regulus held James’ eye contact and swallowed. Regulus had just had his second orgasm of the night, he wasn’t sure how much he had left to give. But looking up at James as he turned to Lily and pulled her into a proper snog, caused him to feel the familiar twinge in his groin that signaled a readiness he didn’t know he had in him. 

He watched, entranced, as James and Lily’s kisses turned into something hungry; as if their very lifeblood existed within one another. He was so close to them that he could see the trails of saliva that connected them as they gasped into one another, desperate for more. Regulus was mesmerized, as he felt the hand that had been circling his back drift slightly lower. His spine seized slightly involuntarily, a shockwave of pleasure and anticipation shooting through him. Lily’s hand dropped even lower, teasing the skin beneath his trousers. Regulus thrust forward into James involuntarily, and he could feel James’ hardness returning as well. He wondered to himself if James had taken a stamina potion when Regulus wasn’t looking because how was this man still so hard? 

Lily’s delicate fingers slipped under the waistband of his pants and Regulus felt her teasing at the cleft between his arse. He knew where she was headed and the idea of it was making his head spin. Regulus let out a not-so-quite moan into James’ chest as Lily’s nimble fingers found home, and she began to prod at the tight ring of muscle. He felt James’ body move slightly and it wasn’t until he heard the whispered ‘lubrificare’ and felt the familiar flooding of warm slick up his arsehole that he realized James had gone for his wand. 

Regulus hadn’t even a moment to process before a long thin finger was sliding into his arse, swirling and stretching him in the most glorious way. Regulus let out a long, stuttered growl, only half aware that he was dripping drool onto James’ pectoral, so completely and utterly blissed out. James curled one of his hands into Regulus’ hair, and the other took over for Lily on his back, rubbing soothing circles into him. 

Regulus couldn’t help the little jolts that his hips made as Lily prodded at his back door, and he reveled in the feeling of her finger inside him. 

“More, please, Lily, please,” he begged and she responded with a kiss to his shoulder and added a second finger in with her index. Regulus mewled loudly, gobsmacked that he was so turned on so quickly after coming for a second time. Even if there wasn’t literal magic at play, something magical was happening to him. 

Lily hooked her fingers, clearly searching for the spongy bit of muscle, and Regulus keened when she found it, gasping for air and swearing profanities into James’ chest. Lily was relentless, creating a steady rhythm with her fingers, able to both maintain a steady pressure on his prostate and scissor her fingers, stretching him deliciously. This was absolutely not her first time fingering a man’s arsehole, Regulus thought to himself as he pushed back against her hand, fully helping her work him open. 

It wasn’t till she added a third finger that Regulus started to lose control. Unencumbered whimpers left his mouth as she stuffed his arse, thrusting with purpose as she built him up to his third orgasm of the night. His poor cock was now rock hard, still wrapped up in his trousers. But that didn’t stop him from rutting with increasing necessity against James’ thigh. 

James trailed the hand that had been tangled up in Regulus’ hair down toward his hips, the hand on his back coming to meet it. With a strong but gentle touch, James hooked his fingers into Regulus’ side and ground their hips together.

Between the friction of his and James’ thighs and Lily with three full fingers deep in his arse, Regulus was close. He panted heavily, crying out with every stroke and new sensation. 

“That’s it, Lily. He’s so close, you’re doing so good, fucking his arse with your hand like that. I bet he feels so good, doesn’t he Lil?” 

“He’s so fucking tight, James. He’s clamping so hard on my fingers it’s almost hard to get them in all the way.” 

Regulus tried to contribute to the conversation, but all that came out was a drawn-out moan, causing Lily and James to snicker to one another. 

“You’ve got him so worked up Lil, I bet he’s just begging to come again with your fingers knuckle deep in his arsehole, isn’t he?” 

Lily continued to pump in and out of Regulus, the knot in his gut curling tighter and tighter. If he hadn’t come yet tonight he probably would have by now, the way she was stroking his inner walls, deftly playing with his most sensitive spots. But this orgasm she was drawing out of him was the tsunami to his previous tidal waves. It was taking him a while to get there, but because of that, he was able to feel every sensation that much more intensely. He had never felt so much lust in his life before and, sandwiched between the two most attractive people he had ever met, he was in heaven. 

Lily was helping him climb higher and higher, his whimpers getting more and more desperate as he rocked against James, his hands still tucked around James’ torso, feeling each rivet of James’ ribcage as he worked himself up. Regulus could feel the crest of the orgasm coming, he rutted his hips desperately into James’, digging his nails in and pushing back on Lily’s fingers just as eagerly. 

“Lily, James,” he panted, quietly, completely swept up in the feeling of a thousand nerve endings being lit on fire, when all of a sudden, it stopped. 

Lily had removed her fingers. 

Regulus cried out in anguish, “No, please, more, let me finish, please, I need to fucking cum.” He tried to rut against James’ leg but James held his hips in place, lifting Regulus slightly off his lap so Regulus was left thrusting into mid-air, untouched and desperate for his release. 

“Shhh.” James whispered into his ear. “We’ll take care of you, don’t worry.” 

Regulus let out a groan of frustration, looking up and staring daggers into James’ eyes. 

“We just figured it might be time to get you out of these trousers, love,” Lily said, pressing herself against Regulus’ back. 

“Oh fuck yes, finally, please.” Regulus nearly shouted that last word, his cock hard and aching. 

He felt Lily pull back and, as if in unspoken sync, James flipped Regulus so he was on the bottom and James and Lily hovered over him, looking down at him with hungry smiles on their faces. 

Sweat was starting to drip down Regulus’ forehead as he reached down for his belt, Lily slapping his hand away. 

“Mine,” she whispered into the zipper, slowly unbuckling his belt, and Regulus almost came again. 

With a sigh of relief, he felt the pressure against his cock lift as Lily pulled his trousers and pants down in one rough tug. She wasted no time in pulling them straight off his body and tossing them across the room. James, at the same time, pulled at Regulus’ shirt, pulling it clean off his torso.

“So pretty,” James said, so softly Regulus thought he might not have intended it to come out at all. Regulus kept his eyes on James, watching his eyes trace over every detail of Regulus’ face, catching frequently on his mouth. 

With a moment of clarity and confidence that being stripped bare had empowered him with, he reached up and pulled James by the neck down to meet him, tongues crashing hungrily against each other. Kissing James was like coming up for air after being meters deep in the ocean, rocketed around by violent currents. He was breathing life into Regulus’ empty lungs, and Regulus could feel himself becoming addicted. 

James backed away and Regulus felt his face being pulled towards his other side, opening his eyes to meet brilliant green ones. He smiled at Lily, overwhelmed by her beauty with this close of a view. He felt a strong hand sneak between his legs as he examined every soft freckle that dotted her cheeks and forehead, spotting a row of slightly crooked bottom teeth that charmed him, and admiring the way her hair was softly curling around her temple from the moisture collecting there. 

Her kisses were softer than James’. They were tender and slow, more exploratory, allowing Regulus and Lily to meld into one as they brought their mouths together again and again. The duality of James and Lily together was electric. Regulus could picture the way he might love them both. They were different loves, but complementary in a way that he couldn’t imagine one existing without the other. 

For just a moment he let himself imagine what that would be like, as he lay sandwiched between them, Lily’s lips on his, James’ hand on his cock. This was bliss, there was nothing better. In this moment, for just a few shared breaths, they three had become one, and he could have this. 

He couldn’t though, would never actually have it. He knew that. James was Lily’s, and Lily was James’. Regulus didn’t fit into their equation, and that was okay. It had to be okay. But he would bask in the sun on a bed of flowers for as long as they’d have him. 

Regulus felt the hand on his cock slow as Lily shifted her hips, bringing her pelvis in line with his. James’ hand guided the tip of Regulus’ hard length forward until he felt it come into contact with what was unmistakably Lily’s cunt. She was dripping wet and it took nearly no effort for James to capture enough moisture with his head and spread it down the length of Regulus cock so that he was slick. 

“Are you ready, baby?” James whispered in Regulus’ ear, nipping lightly at the lobe, causing a full-body shiver to rock through Regulus. 

Regulus looked at Lily, waiting for confirmation this was what she wanted too, and she nodded at him, bringing her hand down to grip his hip and pull him closer, the tip of his cock slipping inside her. 

“Fuck,” Regulus growled as he wrapped his arms around Lily and pulled her closer to him, impaling himself the rest of the way inside of her. 

Lily let out a wail of pleasure and dug her hands into his hip, likely leaving a row of crescent marks that Regulus would enjoy viewing tomorrow. 

The inside of Lily’s cunt felt like heaven, she was so unbelievably wet and Regulus could feel himself growing even harder at the idea that he had had some hand in doing that to her. Her walls clenched down on him as he started to thrust into her. She threw one leg over Regulus’ hip and the new position made it easier for Regulus to go even deeper as he bottomed out again and again.

“Fuck, Lily, you feel incredible, best cunt I’ve ever had.” The last few words were punctuated by the slamming his hips into hers, delighting in the high-pitched moans that were cascading from her swollen, cherry lips. 

“Feel you so deep Regulus, love your dick in me, please keep fucking me with your big fat cock,” she begged, and Regulus obliged, ever the gentlemen. He slid one hand down Lily’s front, to play with the bundle of nerves at the apex of her thighs. As soon as his fingers made contact she screamed and her body convulsed. 

“Fucking Merlin, don’t stop, I’m so close.” She writhed on his cock, hips moving in time with his, pushing herself further into Regulus’ playful strokes of her clit. 

“No, love, not Merlin,” he said sweetly into her ear, “You’re fucking Regulus,” and with that, she shattered around him, and Regulus followed suit.  Her inner walls clenched hard on him as they both rode out their orgasms. Regulus threw his head back into James’ chest while also getting a hard grip on Lily’s arse and pulling her forward as far as physically possible into his cock as he rutted inside of her. Her walls continued to pulse, milking every last drop as Regulus continued to spasm, riding out his third orgasm of the night.

Lily ground small circles with her hips into Regulus, a blissed-out look on her face as she stared up at him. Regulus, feeling slightly lightheaded grinned back at her, leaning down to pepper light kisses on her forehead. 

“Lily, that was…” he trailed off. His brain, which was usually chock-full of obscure and poignant descriptive words, was completely at a loss. There wasn’t a word in the English dictionary to describe what fucking Lily felt like. 

Lily, thankfully, took his silence as a compliment and reached up to brush her lips across his delicately. 

“Why thank you,” she giggled, her hips fully locked in with his, and Regulus quite enjoyed the feeling of going soft inside of her. “And this cock,” she gave her hips another experimental swivel and he groaned at the overstimulation, holding her still against him, but not pulling out, refusing to let this moment end. “Fucking delicious.” She licked her lips, keeping her eyes on him, and Regulus, to his bewilderment, twitched slightly inside of her. 

“She really does have the most delectable cunt, doesn’t she?” James contributed, leaning slightly over Regulus, his body pressed up completely with Regulus’ back. “Being inside her is my favorite place in the world.” 

Lily mewled at the praise. 

James ran a light touch down Regulus’ side, causing gooseflesh to erupt across Regulus’ arms and legs despite the warm heat that surrounded them on the bed. 

“I do, however, have an opening for a second favorite place.” Regulus couldn’t see James but the flicker of heat in Lily’s eyes was surely replicated behind him. Regulus felt his insides squirm. “Shall we see if that place might be inside you?” 

Regulus let out an involuntary moan and instinctively pushed his hips back against James’. His cock twitched again at the insinuation, shocking even Regulus with a basically non-existent refractory period. 

James trailed the hand that had been running down Regulus’ body even further, in between the cleft of his arse and pressed lightly against his already stretched hole. 

“Yes please, fuck, please fuck me, James.” Regulus spluttered, the words coming out louder than he had intended.  

James groaned. “You have no idea how long I’ve wanted you to say that,” James admitted, and Regulus didn’t have time to dissect that sentence before James was casting another lubrication charm and lining up his cock with Regulus’ arse. 

“I’ll go slow, baby, take from me what you need.” James slowly pushed forward, and Regulus felt the head of James’ cock bypass the tight ring of muscle, finally entering him. 

James was the largest cock Regulus had ever had inside him, and despite being well-versed in the ways of bottoming, the stretch was intense. James, sensing Regulus’ discomfort, paused, giving Regulus a moment to adapt. 

“He’s so big isn’t he?” Lily, still wrapped around Regulus’ front, spoke into his neck, lifting off from where she had been making little love marks on his throat. “And just wait till he starts going. He knows how to fuck so well.” Regulus moaned, his body relaxing around James, giving him an experimental push of his own hips. “Oh, he’s so strong, he’ll fuck you so hard you’ll feel him in every breath you take, in every word you speak, he’ll become so deeply entrenched in you you’ll never be able to wash him away.”

“Fuck, Lily,” James groaned, shifting his hips further into Regulus, the slip of the lube making it easy. “If you keep going on like that I’ll cum before I’m all the way inside of him.

Fuck, he’s not all the way in yet?

Regulus wasn’t even sure he could take all of James, but he wasn’t backing down now. No matter how tight the fit was, Regulus would be taking all of James Potter up his arse tonight.

He was determined. 

Regulus moaned, relishing in the delicious stretch that was becoming more pleasure than pain. “More, please fuck me, James.” The words came out in a whimper, Regulus starting to get desperate again. 

“Of course love, anything for you,” James pulled back and thrust forward again, this time with purpose, hitting even deeper than before. “I just have one request.” Jame’s hips rolled back, pulling himself nearly out of Regulus before slowly, torturously, thrusting back in. 

“Yes, anything. Please, James.” Regulus was a mess. He could hear the sounds of lube squelching behind him but he didn’t have it in him to be embarrassed, all he could think about was getting more of James Potter’s cock inside of him.

James’ grip on Regulus’ hips tightened, holding him still as he wriggled to sink backward onto James’ cock. “I want you to stay there, and let Lily warm your cock while I fuck you. Can you do that for us, pretty boy?” 

Regulus gasped out a pathetic “Yes,” his hands finding Lily’s hips again and crashing them against his own. He hadn’t yet pulled out, but Lily and Regulus let out identical moans as he buried himself back deep within her, feeling the way the combination of her slick and his cum coated her walls and his cock. He was now half hard and growing by the minute. He knew Lily could feel him thickening within her as she wiggled against him. 

“Now now, Lily, I said cock-warming, not fucking.” James snapped his hips again, thrusting into Regulus who unwittingly thrust into Lily. “Can you stay still like a good girl and warm his cock for us?” 

“Fuck, yes, he’s getting hard in me again he feels so good.” Lily threw her head back, dragging her hands up and down Regulus’ chest. “Can I touch myself, James?” Regulus watched her hand dip to his V, dipping quickly to brush the root of his cock and swipe some of their combined mess onto her fingers. He watched, entranced, as she brought her sticky digits to her clit and began tracing slow circles around the sensitive bud. Regulus couldn’t get over the erotic sight of her rubbing his cum into her clit, and he tightened around James who let out a groan in response. 

“Feels like you’ve made that decision for yourself, love,” James panted, resuming his thrusts into Regulus from behind. “As long as you keep those hips still, babe, you can play with yourself all you want. Lily was clearly wasting no time as he felt her pussy contract around him. He was now fully hard and finding it difficult not to thrust into her. James however, was happy to provide a distraction, as he finally slid all the way home and Regulus let out a loud yell of pleasure as James split him open on his massive cock. 

“Fuck yes, James, you’re so deep. Fucking do that again!” And he did. Over and over again James thrust into Regulus, pulling out nearly all the way before rutting back into him again, and Regulus had never felt anything like it. Every nerve ending in his body was on fire with the way James fucked him. Regulus had imagined this and was thrilled to report that reality was better than even his wildest fantasies. Here he was, his arse stuffed full of James while he was balls deep inside Lily. Nothing could ever be better than this. 

That was until James proved him wrong. He shifted his hips slightly, scooting down Regulus’ body and holding up one of his thighs, and that slight change of movement made all the difference. James was now, repeatedly, thrusting up against Regulus’ prostate and causing Regulus to see stars. The scream that left his throat was raw and uninhibited; Regulus would look back on that time and guess it wasn’t the most attractive noise he had ever made, but in the moment there was nothing he could think about besides the pure pleasure that had been ignited in every fiber of his being.

“Ha,” James snickered into Regulus’ back, “fucking knew I’d find it.” 

Regulus could do nothing but babble incoherently in response, his body so intensely overcome with feeling that it was acting of its own accord. He was only slightly aware of his hand reaching back over his shoulder to grasp James by the back of his neck, pulling him closer, desperate to feel whatever piece of him he could. His other hand was wrapped up in Lily’s hair, which he gripped, pulling a low guttural moan out of her. 

He could feel James’ pace start to stutter, and Regulus knew he was getting close, so he thrust himself back on James’ cock, desperate to reach nirvana with him. 

“Fuck, Lily he’s too tight I’m not going to last much longer.” 

“He’s so fucking hard inside of me and you look so hot fucking him, James. I’m so close just watching you two.” 

Regulus grinned, the idea of his two lovers talking about him as if he wasn’t there while also being inside one another was entirely erotic. 

“I think it’s time you fucked him, Lily. Let’s take our boy to the stars.”

“With pleasure,” Lily replied, withdrawing her hand from her clit so she had more room to maneuver her hips as she began to rock herself back and forth on Regulus’ cock. All three of them let out identical groans as Lily and James got into a grove, matching each other stroke for stroke so that when James penetrated Regulus, Regulus was fully encased within Lily. 

It was pure willpower and a desperate need to not let this moment end that kept Regulus from coming, but even he had his limits. He was screaming towards the edge of the biggest cliff of his life and he knew it. But, before he got there, if this was the only time they were going to be together, he had one more thing he wanted to experience.

“Let me,” he stammered out, his breaths coming in short spurts that were cut short by James’ relentless thrusts, “try something.” 

Both James and Lily came to a sudden stop, and for just a moment the only thing to be heard was the sound of three people catching their breaths.

“What do you need, love?” James whispered into his ear.

“Whatever you want, it’s yours,” Lily spoke against his mouth, her lips cresting his with every syllable. 

“I want to fuck myself on you. Both of you.” James groaned from behind him and Lily smiled. 

“By all means, fuck us Regulus,” Lily smirked, pulling him down and capturing him in a searing kiss. 

Regulus deepened the kiss, exploring her mouth with his tongue as he thrust into her, which had the intended effect of nearly pulling himself completely off James. Lily whimpered into his mouth as he drew out of her, pushing himself hard down on James’ cock, eliciting a “Bloody hell,” from James. 

Regulus started slow, delaying the edge that he had been about to topple over. At this speed, he could savor every inch of Lily’s cunt as he fucked her, and every ridge of James’ cock as he fucked him. He rocked between them, enjoying being solely responsible for all three of their pleasures, delighting in every moan and groan that spilled from their lips. 

The crest crept up on him again and Regulus began to lose control, picking up the speed of his thrusts as he truly and fiercely fucked his two lovers. He could feel Lily’s pussy start to pulse around him and knew she was close. James was behind him, letting out a string of never-ending curses and Regulus knew the end was near for him too. 

Regulus wanted them all to come together, completely unburdened. 

“Okay, fuck me, please fuck me,” he moaned, releasing them from his request and they responded with enthusiasm. James began to immediately pummel him from behind, which made Lily’s work of grinding on Regulus’ cock that much easier. The room echoed with a symphony of moans that were progressively getting louder and more high-pitched. 

They fucked with abandon, chasing their respective highs, using each other for pleasure while working together to create something beautiful. Regulus had never felt so in tune with two other people before, like they could sense what he needed and gave it to him, and him them, without so much as a word. 

Regulus felt one of James’ arms come around his body and slip between Regulus and Lily, and Regulus knew instantly that he had found her clit as her pussy clamped down hard on him. She lasted all of another thrust from Regulus before she shattered, her head thrown back, wild, red hair everywhere, her scream coming loud and long. Regulus’s own orgasm overtook him as Lily’s cunt shuddered around him, milking his cock and pulling him deeper inside of her. James followed in quick succession, giving a feral shout as he rutted into Regulus, and Regulus could feel James’ warm release shoot deep within him and he sighed in utter bliss as the three of them wrapped themselves up tight against one another, recovering from their collective orgasms. 

It was a few minutes before anyone spoke, minds drifting lazily in the afterglow, preferring to communicate with light touches and soft kisses instead. Regulus was the first to break the silence. 

“That was, without a doubt, the best fuck of my life.” Lily giggled and James’ hand gripped tighter on Regulus’ waist. 

“I think I can speak for both of us,” Lily smiled, nodding at James, “and say the feeling is mutual.” 

“Hey, you don’t know that!” James retorted playfully.

“James Potter I took your virginity, I’ve been there for every single one of your fucks and this was, by far, the best one.” 

James continued to trail featherlight touches across Regulus’ skin. “Okay, she’s not wrong,” he whispered into Regulus’ ear, “but don’t tell her that. She’s got a bit of a big head about being right all the time.”

“Excuse me, James Fleamount Potter! I am right here, I can hear you.” Her tone sounded annoyed but her face was anything but. A huge smile was plastered across her face as she reached up to play with Regulus’ curls. He usually wouldn’t allow such behavior; but for Lily? Anything for Lily. 

“What’s that, love? Can’t quite make out what you’re saying.” Regulus could hear the sarcasm in his voice as James rolled over slightly, breaking away from Regulus, and Regulus immediately felt his heart drop at the lack of him. He turned his head, watching James reach for his wand on the bedside table. He brandished it over the three of them, casting what must have been a nonverbal cleansing spell, as Regulus felt the layer of sweat and cum that had collected on him over the course of the last hour disappear. 

James rolled over again, shifting closer to Regulus, and pulling up the comforter over the three of them. 

Regulus swallowed, the familiar twinge of anxiety creeping in. Were they going to bed now? This was probably his moment to leave, but how was he supposed to do that? He was trapped between them, Lily’s head on his chest while James had one leg thrown over his own. 

“Um,” Regulus cleared his throat awkwardly. “I guess I’ll get going then.” He moved to untangle himself from them, but when he made eye contact with Lily he was frozen by the sadness in her eyes. 

“What?” she asked, pushing up quickly on her hands and looking at him questioningly. “Did we do something wrong?” Regulus could hear a note of panic in her voice. 

“No, of course not,” his voice stuttered but felt his body relax when he saw the relief wash over her. “I just thought it was time for sleep, so I better get back to my room.” He could barely get the words out, the idea of leaving these two, after the night they had just had, broke his heart. But they weren’t his, this wasn’t his room, wasn’t his relationship, and whatever this had been was now over. He knew his place, and it wasn’t here. 

He moved to pull back the covers and quickly scrambled down the bed to slide out the bottom of it before his nerves got the best of him. He realized quickly that he was naked, something he wasn’t entirely comfortable being despite having just fucked the only two people who could see him. And so he brought the comforter with him to wrap around his body, exposing Lily and James in the process.

Those two, unlike Regulus, were fully comfortable in their nudity, and he was struck dumb momentarily just looking at the two of them, sprawled out on the bed and looking so thoroughly fucked. The 18th-century European Masters couldn’t have painted anything more beautiful. 

James stretched and watched Regulus struggle with the comforter while looking for his clothes. 

“Regulus, love, get back in bed.” 

“I don’t think I have another round in me.” He blurted and both Lily and James laughed. 

“No love, don’t think we do either. I’m talking about to sleep. Sleep here, Regulus. Don’t go back to your own room.” Regulus could see the want in James’ eyes as he stared at Regulus, but he still hesitated. 

“Please, Regulus,” Lily whispered.

Well, that was him done.

All resolve dropped, Regulus smiled and slowly clambered back into bed, pulling up the comforter with him. 

James and Lily snuggled into him once more, and one of them cast a nonverbal Nox as the candles went out. 

“I’m not overstaying my welcome?” Regulus’ anxiety asked for him. 

“No, love, trust me when I say we want you here,” James replied, his voice low and gravely from overuse. 

“Regulus do you really think James and I would plot for months on how to get you into our bed just to kick you out the second it was over?” 

Regulus turned to where Lily’s voice was coming from, absolutely struck dumb. 

“What? Months?” 

“Yes love, you were quite the challenge. Too noble to hit on your mate’s girlfriend, which, in any other situation would be an honorable trait.” James added. 

Regulus thought back to all the times he had caught Lily’s eye and felt her linger. He recalled that one night when they were visiting Potter Manor and she asked him to help her apply suncream. He also thought the time she had suggested he was probably great in bed just from the way he ate a banana. The signs were all there and he had seen them but every time had talked himself out of them. He never would have believed Lily would cheat on James, it was unthinkable. But if James were in on it.

“Bit slow on the uptake weren’t you?” James teased, poking him in the side.

“I still don’t understand. You planned this?” 

“Well, we didn’t know if anything would ever happen. Lily thought you might have had a crush on her so that’s why we started there. But we had no idea if you actually did, and even if you did, would you also be into me? It was all just a hope and a whim. I don’t actually think we ever thought you’d feel the way about us the way we do about you, but…” he trailed off. “Here we are.” 

“And where is that? Where are we?” Regulus said, holding his breath. 

“Well,” James laughed, “technically we’re in our bed, naked. Hey, I can sense you rolling your eyes even if I can’t see them, Reggie.” Regulus had, in fact, just rolled his eyes, and being called out on it made him want to roll them again but he resisted. 

“I meant, what is this? What are w-?” He had more he wanted to ask but to put it all out there on the table was terrifying. He figured at least Lily would know what he meant. He could be seconds away from having his heart broken, and his body started to tremble as he waited for a response. 

“Truthfully, I’m not sure yet,” Lily said delicately, “What I do know, is that I like you, and James likes you, and clearly we all have incredible sexual chemistry. We’d like to explore more, but if sex is all that this is for you, we can handle that, and obviously would like to keep having sex with you.”

“No-” Regulus blurted, trying to wrap his mind around what Lily had just said. They liked him?

“No?” She sounded crestfallen. 

There was a pause before James added, “That’s okay too, Regulus. It’s totally up to you. If this was a one-time thing we can go back to just being strictly friends, we’d never dream of-”

“No,” Regulus repeated, cutting off James’ words that were searing his heart. He couldn’t hear the rest of those words come out of James’ mouth. “No, it’s not just sex, it’s not just a one-time thing.” 

Regulus was grateful for the lack of light as he could feel his face heat as he struggled to get the words out. “I like you, like you both. Have since school, that’s why there was never anyone else. No one serious, anyway. I’d always compare them to you and nobody was more aggrevatingly handsome than James or kinder than Lily. You two were always it, even if I coudln’t admit it to myself, but I never…” his voice wavered, suddenly overcome with years of emotions he had repressed, all tumbling out in this confession. “Never thought you’d see me that way.” 

“We see you,” Lily said, as James’ arm slinked over Regulus’ torso and across to Lily, pulling them together into one big horizontal hug. 

“At the risk of doing this a little backward, any chance you’d say yes to us taking you on a date?” James asked softly.

Regulus’ cheeks hurt from how wide his smile had grown. Now he wished he could see James’ face, wanted to know if he was nervous. Oh who was he kidding, James Potter was never nervous. 

He let the question hang in the air a moment, and he could hear both Lily and James holding their breaths. 

“After that performance? I think I’ve earned two dates.” 

Lily and James let out twin sighs of relief and they all collapsed into giggles. 

“Oh, I love that idea! I can plan one and James can plan the other, so you can see the whole gambit of what you’d get by dating us.” 

“Deal, as long as at least one of them ends with us back here,” James added. 

“That is a guarantee,” Regulus said shyly, overwhelmed by how full his heart felt. Here he was, lying between the two best people he knew after they had just fucked his brains out, and they were now confessing long-held feelings for one another. Regulus wanted to pinch himself because there was no way this could be real. 

“Sounds like a plan.” James kissed Regulus lightly on the top of his head. “Goodnight, love, and don’t even think about sneaking off in the middle of the night, we know where you sleep and we’ll just join you there.” He added jokingly. 

“Goodnight.” Regulus sighed and immediately fell into the best sleep of his goddamn life. 

~~~~

James wandered into the kitchen early the next morning, he was always up earlier than Lily and it seemed Regulus as well. He had managed to find his pants without making too much noise and had left his lovers tangled up with each other in the bed. 

He nonverbally accioed three glasses from the cabinet and set about filling them with water when Sirius entered the kitchen. He looked like shit, his hair sporting a million flyaways from his usual nighttime bun and dark circles rimmed his eyes. 

“Prongs, you bastard.” James’ stomach dropped out from underneath him. Had Sirius seen something last night? Did he know about them and Regulus? Obviously, he intended to have this conversation with Sirius at some point but he hadn’t even known if Regulus was into them until eight hours ago and hadn’t seen the need to open that can of worms if Regulus wasn’t interested. But James couldn’t help but feel guilty if the discovery of their new relationship had bothered him so much it had kept him up all night. 

“I’m sorry?” James said hesitantly, waiting to hear just what he was apologizing for. 

“How many times have I told you, if you and Lily are going to have marathon sex sessions, ” he paused to give James a cheeky grin and nod of approval, before settling back into his serious tone, “for the love of Merlin please use a damn silencing charm!” 

James relaxed, a smile spreading across his face. He was an idiot for forgetting, but in his defense, there was a lot going on last night. Thank Merlin Sirius didn’t realize those sounds he heard coming from James and Lily’s room also included those of Regulus’ making. There are some things a brother never needs to know. 

“Oh fuck mate, sorry about that one. Got a little carried away.” He couldn’t meet Sirius’ eye but felt the blush heat his cheeks as images of the night before began replaying in his mind. 

“Yeah, yeah, I’ve heard it all before, and I’ll probably hear it again. Just try, at the very least for Remus’ sake. You know how shit he sleeps on a good night, hearing you fuck the shit out of his best friend really doesn’t help.” 

“Yeah, fair enough,” James smiled, a shit-eating grin struggling to break through. 

“What did you guys even get up to last night? Try something new? You two sounded absolutely feral.” Sirius smiled, leaning his elbows on the counter and placing his head in his hands. “Tell me everything.” 

Sirius was such a nosey fucker, and nine times out of ten, with Lily’s permission, James would happily share the many ways in which they experimented in their physical relationship. 

“Yeah,” he chuckled, “you could say we tried something new.” Or someone.

James heard a noise come from down the hall, and both he and Sirius whipped their heads around. It was the unmistakable sound of a woman’s moan. 

Sirius looked back at James in disbelief. “No way she’s really going at it herself this morning after what you two got up to last night?” 

Sirius really was way too comfortable with them. 

“Ha,” James laughed awkwardly, knowing exactly what was happening and praying to all the Gods, Muggle and Magical alike that they wouldn’t give themselves away. “You know Lily,” James shrugged and waved his wand, levitating the three glasses of water into the air just as a distinctly male voice cried out “Oh, fuck, Lily!” 

Sirius’ eyes went wide, as he stared at James, then down to the three glasses of water, and then back up at James, confusion shifting into horror painted across his face. 

“Oh, Regulus! Fuck you feel so good!” 

James ran. 

“James Fleamout Potter, I will fucking kill you!” Sirius bellowed from the kitchen as James sprinted down the hall, barreled through the bedroom door, slammed it shut and cast a quick locking spell followed by a silencing spell. 

Both Lily and Regulus looked up at him in surprise. They were facing the door, Lily was on her hands and knees and Regulus was behind her, fucking her doggy style. His hips slowed as they took in James’ panicked expression. 

“Well,” he threw his back against the door, holding it in place as it rattled on its hinges. “I think Sirius knows.”
