Of all the things in the world Sirius Black could have uttered into Remus’s skin after ten agonising minutes of his mouth along Remus’s length, “I wanna watch someone edge you,” was probably the most out of pocket option.
Still panting, still deliriously hard, and not quite able to think clearly with all the blood in his body pooling in his groin, Remus blinked confusedly down at the grey pair of lust blown eyes and muttered a confused, “what?”
Sirius’s grinning mouth pulled in a way that told Remus he was about to be broken down and tortured for god knows how long before ever being allowed to come while a loose and distracted hand moved along his cock with a deeply unsatisfactory pace. “I mean— I would love to have a third person that I could use to edge you, while I top both of you.
Remus’s eyebrows raised in incredulity, and he pushed himself up on his elbows to look more fully at the infuriating and beautiful man between his legs, “we’ve only been together four months and you’re already bored with me?”
The soft laugh that rumbled through Sirius’s chest told Remus he had expected that response. He tightened his grip on Remus’s neglected erection and stroked more purposefully, forcing Remus to groan out a pitiful, stuttering sound, falling back into the pillows. Sirius, the smug bastard, stroked him a few more times before tonguing the head of his cock teasingly, sucking gently, not giving Remus the satisfaction of being allowed to sink fully into the wet heat of his mouth.
“How could you think I’d be bored of this?” Sirius asked, his voice low, his hand loose again.
Remus’s panting breaths were laced in frustration as he pushed a shaking hand through his own sweaty hair, the other gripping the sheets beneath him in an effort to stop himself from lashing out.
“And who, pray-tell, are you so keen to invite into our bed?” Remus asked, trying so very hard to keep his voice even and calm.
“Oh, it doesn’t matter. Could be anyone.” Sirius grinned, still not really giving much away. Not really explaining.
“Anyone?” He asked incredulously, squeezing his eyes shut against his frustration, still trying to stay calm as Sirius’s hand continued to tease him mercilessly with its nearly useless grip.
“Yeah, anyone. It doesn’t matter.” He explained with a low, taunting voice.
“Really? Even Lily? Peter?” Remus offered scathingly, with a nonsensical gesture of his hand.
“Sure, why not?” Sirius was smirking. “The more the merrier.”
“Oh my god, stop, I was being facetious.” Remus protested with a snort. “Even James?”
“Oh, gods, no.” Sirius shook his head, grimacing at the thought. “That’s where I draw the line, that’s practically incest. I’ve broken that family tradition.”
“Oh my god—” Remus deadpanned.
“What matters—" Sirius interrupted, “is that I get to watch them bring you to the edge, over and over—" he punctuated this with a firm, sliding grip, pulling a haggard whine from Remus.
“And, each time,” Sirius’s hand was suddenly flying over Remus’s cock, the pressure and speed shocking him into delirious shouts of anguished pleasure. An orgasm was coiling in his gut, causing him tense and pant and moan, and just as he was about to reach the edge, just as he was about to tip over, Sirius let go. “I get to pull them away before you finish.”
“Fuck—" Remus sobbed loudly, angrily. He was so furious and so turned on it was derailing his ability to think.
“Don’t you want to know the rest?” Sirius asked with a mocking concern, his hands resting on the top of Remus’s thighs, thumbs stroking the creases of his groin.
“No." Remus bit, trying to sound warning and unimpressed, but it came out too shakily, too desperate and breathy.
Sirius laughed, and began pulling himself up Remus’s body, taking care to keep himself away from touching Remus where it mattered.
“What's wrong?” Sirius asked in a low voice, wet mouth to his collarbone, body hovering over him. Remus’s hands had reached blindly to grab at Sirius the moment the man was in reach and tried desperately to pull him down towards him.
“Sirius, please,” his voice cracked pitifully around the plea.
“Please what?” He was holding himself back, not giving in to Remus's insistent hands.
Remus growled a frustrated sound. “Please can we keep having sex?”
“No, I have to tell you the rest of my plan.” His voice was low and breathy against Remus’s neck, his teeth dragging along scared akin.
“Then, hurry up and tell me.” Remus snapped, hands frantically seeking in Sirius’s thick hair. The smell of neroli and sweet orange was strong, pulling at Remus’s heart, at all the aching memories of wanting to touch Sirius and not being allowed to. It made him even more needy for contact.
“Not with that attitude.” He admonished mildly, his mouth working up Remus’s neck to his jaw.
Taking a deep, fortifying breath, wrestling down the acerbic whine building in throat, Remus managed a passably even tone. “Please tell me.”
Humming approvingly, Sirius’s mouth made its way to Remus’s and neither of them could hold back the soft sighing moans as their lips pressed together, as Sirius’s tongue slid along his.
Pulling back, Sirius said, “Well, after they’ve edge you until you’re screaming, then you have to watch me fuck them.”
Something ugly and painful twinged in his gut at the thought of Sirius fucking someone else. In fact, he wanted to be offended by the mere suggestion, wanted to let the flicker of hurt in his chest build into something he could nurse with his self soothing petulance. Let all of his insecurities about his inexperience and Sirius’s history and the newness of their relationship swallow him whole.
Sensing Remus’s teetering mood, Sirius kissed him softly, sweetly, before whispering with that reassuring voice of his, “it doesn’t have to be real, Remus. It’s just a game. I’m just teasing.”
Remus huffed, feeling transparent and a little embarrassed about it.
“That’s what I mean when I say it doesn’t matter who a third person could be. Because it doesn’t. What matters is the ‘you’ part. The part where I get to use every tool at my disposal to make you feel good.”
“Oh.” He breathed, his heart speeding up. It felt like Remus was being pinned down by Sirius’s gaze. His grey eyes holding him in place, not allowing him to dissolve into his self deprecating defensiveness.
“Yeah.” Sirius agreed, peppering his face with adoring lips. “If you were interested, we can talk about it later. And if you’re not interested, then it doesn’t go beyond this. Beyond me using the thought of it to drive you mad.”
Remus pushed his hand through Sirius’s curls and brought their lips together. He was feeling grateful for being seen so clearly, for the reassurance, for the knowledge that it was okay to have feelings and be inexperienced.
Moving his knees between Remus’s legs, Sirius finally brought their bodies into contact, sliding against him. Remus sighed in relief, the pressure on his now semi flaccid state reigniting the heat in his groin.
“Okay, so—" Remus was trying to rally his sense of confidence, trying to lean into the playfulness that Sirius was so good at and that left himself so wrong footed. “They edge me, you fuck them, and then what?”
“And then, if you’re well behaved, you can come.” Sirius was smirking again, slowly and languidly rolling his hips against Remus who was running his hands down Sirius’s back to grip his ass, his fingers digging into firm muscle, trying to urge Sirius to move faster. Quickly swelling back to full hardness, he felt deliriously close to the edge, having been held captive on the precipice for so long.
“How?” Remus asked a little breathlessly, trying not to be too demanding and desperate but failing abysmally, his hips rolling upwards, chasing relief.
Sirius’s voice had dipped even lower, his breath hot against Remus’s moaning mouth. “I’d fuck you while your gagging on someone’s cock, thats how.”
“Oh, fuck.” Why did that set Remus’s blood on fire so quickly? Why did he suddenly want that so badly? Sirius had only topped him once before. It was something he had a hard time with. He struggled to relax, to let go. Struggled to come when he was being breached like that. But suddenly just the thought of it— it made him shudder with anticipation, made his cock throbbed in warning, his gut clenching with a rolling wave of pleasure.
“Would you like that, Remus?” Sirius asked the crook of his neck, thrusting his hips with just a little more pressure.
And that was it. That’s what did it. With Sirius’s teeth on this neck, his teasing voice wrapped around his skin, cock sliding along his own, Remus cried out a startled moan of anguished pleasure as his hips convulsed.
Sirius seemed as surprised by his orgasm as Remus was and it took him a moment to realise it was happening. But as soon as he felt the slickness of Remus’s release, he kissed him hard and deep. And there was something about Sirius’s tongue sliding against his as he came that dragged it out, kept the rolling pleasure shaking through him in several more waves than he was used to.
And as the final feeble thrusts of his hips stilled, Sirius was reaching down to jerk himself off with a frantic, quick hand before spilling over Remus’s stomach, adding to the mess between them.
“Fuck,” Sirius muttered as he fell just to the side of Remus, his face against his bare chest.
“Fuck,” Remus whispered in agreement. His eyes were closed and he was struggling to catch his breath. To reconcile how and why his orgasm had been so startlingly good.
They were quiet a long while, trying to even their breathing before Sirius moved to clean them. Remus felt spent and limp and utterly useless in the endeavour to make himself decent and he was deeply grateful for the care Sirius was showing.
After tucking themselves beneath the covers, Sirius pulled Remus to lay on his chest, soft hands in his hair.
“I was being honest when I said I wasn’t bored with you.” Sirius said softly. “I’m not. I’m perfectly happy. I just like to push your buttons.”
Remus hummed, his limbs heavy, relieved to hear it in the aftermath. “It was fun.” He admitted sleepily, before adding ruefully, “even if it was unexpected.”
“Thats my whole thing.” Sirius laughed, kissing the top of his head. “Fun and unexpected.”
Grinning, Remus squeezed his arms tightly around Sirius before letting his thoughts drift. Perhaps, when he was feeling a bit braver, a bit more settled in this new tentative thing between them, he would have to consider this threesome idea a little bit more.
