Work Text:
They’ve been at the bar for two hours when someone bundles them into an auto-taxi and tells the thing to take them to Gavin’s apartment. There’s a good amount of spiked thirium in Nines’ system, and an equal amount of tequila in Gavin’s.
There’s a shared look across the backseat, heady and heated, and they crash together hard, seatbelts forgotten.
Gavin’s lips press hard, too hard against Nines’ and their teeth clack together. The feeling of metal canines scraping at his lips makes Gavin groan, barely reigning himself in as he takes a breath before he smashes their mouths together again.
The taxi is beeping at him for being unsecured, and he shuts it up by climbing across the seats to straddle the massive android’s lap and grind down on the growing tent there.
He hears Nines’ cooling unit kick on, his frantic breaths matching Gavin’s as the human sucks on his lower lip and coaxes out his tongue.
They moan in tandem, Gavin’s hips making a frantic rutting rhythm against his as he pushes their straining dicks together through layers of fabric.
The skin on Nines’ hands flickers, receding as he shoves them open-palmed up under Gavin’s shirt to slide across his chest. He takes both pecs in them and squeezes, thumbing his nipples, making Gavin arch and cry out against him.
There’s no words exchanged, as they reach their destination, stumbling out of the taxi one after the other and through the lobby.
Nines pins him against the elevator wall, the handrail digging into his back, and shoves two fingers in his mouth. He groans shamelessly, and bites them, as Nines’ lips trail a hot line of tongue and teeth down to his collarbone.
The elevator dings and he doesn’t have to walk. Nines grabs his thighs and carries him like he weighs nothing, his straining cock twitching in his jeans at the feeling of being manhandled. Nines’ own arousal sits hard and heavy against his ass.
They’ve done this before. Hazy, drunk or high, they’ll stumble to his apartment and fuck until Gavin has to call off work because he can’t walk.
He loves it. They both do.
Nines the feeling of Gavin unraveling below him, making space inside him like he was made to fit there, to ruin him until he’s hoarse and wrecked, fuck his throat and his ass until both are sore and he needs to be taken care of.
Gavin the feeling of being filled, over and over, pushed open and used and railed until all he knows is Nines’ name and the sounds of his own pleasure. He likes the way Nines fits in his throat when he fucks it, long and too damn wide, choking him until his vision goes black at the edges and he has to pull back or pass out.
Gavin had joked, their first time, if that’s why they’d called him Nines. He’d regretted it.
The dynamic changes, tonight, when the apartment door clicks shut. A switch flips in Gavin, and Nines seems startled by it. But welcoming, of course.
The smaller man pins the android to the entryway wall, thigh between his legs, grinding the firm muscle there against him as he yanks him down to kiss him.
He can’t leave marks on Nines, but seems determined to, teeth worrying hard on his lip before he runs his tongue over it and drags his open mouth down the curve of the simulated adam’s apple.
Nines moans, low and loud, and with that sound Gavin reevaluates every time they’ve ever fucked.
He’d slipped into the bottom role because it was easy, something he’s used to, but the little huff and broken off whine Nines lets out now when Gavin grabs his throbbing cock through those damned dress pants changes everything.
He murmurs the first words either of them have said since leaving the bar, and is blindsided with how quickly he’s accepted.
“Wanna fuck you, Ni.” he breathes.
“-Please.” the android answers, eyes squeezed shut as he humps Gavin’s thigh like an animal.
Gavin grips his tie and pulls it, hard, yanking him forward and leading him to the couch like it’s a leash. Isn’t that a thought. He follows, obedient, and bends easily when Gavin puts a flat hand between his shoulder blades and shoves him over the arm of it.
Gavin doesn’t even unbuckle Nines’ belt, just yanks his pants and boxers down over his hips and lets them drop to his knees. They haven’t even taken their shoes off, but neither of them can find it in themselves to care, too desperate and heated to think of anything but each other.
Nines moans weakly as Gavin draws his fingers up his perineum, meeting the little ring of simulated muscle he finds is already wet.
“Didn’t know you could do that.” Gavin groans reverently, sliding his middle finger in abruptly with basically no resistance.
“Wet- for you.” Nines stutters through a whine, grinding back against him, back muscles shifting under that too-tight dress shirt— and isn’t that a sight.
“Fuck, baby.” is all Gavin can think to say, pushing in a second finger, then a third when he takes it easy. He pushes hard, with an obscenely wet sound, reveling in the broken “Gav-” Nines lets out as all three fingers thrust in as far as they can go.
“Do you have a-” Gavin starts to ask, free hand working at the fly of his jeans when by muscle memory he presses and crooks his fingers.
“Yeah!” Nines answers breathily when he finds the mimic of a prostate, arching, clawing at the couch cushions as his cock bobs and drips under him.
“Listen to you.” Gavin teases, voice a little bit cruel, groaning as he finally frees his dick from his boxers and gives it a long and slow few strokes. He keeps his fingers curled, pressing hard over and over into that spot.
Nines goes boneless, voice modulated and staticky, legs sliding apart wider as he bucks forward against nothing and gets impossibly wetter under Gavin’s perfect touch.
“Fuck, you’re close already, I can tell. Jesus. You gonna beg for it?” Gavin continues, tone taking on something rough and growly as he scissors all three fingers and stretches him wider.
“Gavin- Gavin- fuck, yes.” he pants, and there’s a small puddle below him now, cock leaking steadily as it twitches up towards his belly, the tip swollen and flushed blue. “Fuck, please let me- Gavin please let me-”
“Yeah, Ni, baby come on. Come for me. Let me see.” Gavin encourages, not slowing for a second despite the ache in his wrist.
The android arches beneath him, back bowed, crying out as simulated muscles grip and pull at Gavin’s fingers. Two more strokes of his prostate and he’s cumming with a desperate cry, burying his face into the couch as he bucks and writhes through it.
“Gavin, Gavin Gavin- fuck me, come on-” he begs, still shaking with the aftershocks when Gavin pulls his fingers out and slicks up his dick.
“God you’re just gagging for it.” Gavin goads, reveling in the little disappointed sound Nines lets out at the loss.
It doesn’t last long before he’s dragging the plush head of his cock through that wetness, the android shaking beneath him as he presses until it pops in.
Their groans mirror each other, and Gavin has to grip Nines’ hips to keep him still as he slides home in one long, smooth thrust that punches the breath out of them both. Nines is so hot, so wet, clenching desperately around him like that alone will draw him deeper.
He pulls back, just halfway, snapping his hips quickly forward in a way that wrenches a half-gasp out of Nines’ poor abused voice box.
“Fuckin’ look at you.” he smirks, rolling his hips in a slow grind that makes his eyes roll back. “Could’ve been doing this the whole time if you told me you wanted my dick so bad.”
Nines scrabbles for purchase on the cushions, still hard and aching between his legs, adding more to the mess on the floor by the second. “Fuck, Gavin- yeah, I’ll- yeah I can be good-”
“Aww, you wanna be good? Wanna get called a good boy?” Gavin grins, punctuating the end of his sentence with a quick jut forward that draws a sob from Nines’ mouth.
“Yeah, I wanna be good.” the RK900 breathes, barely audible over the static from his system being overloaded. He presses desperately backwards, forcing Gavin deeper, closer.
“Wanna come again baby?” Gavin asks, just a little condescending, a little mean. “You gonna come just on my cock? Be a good boy?”
The filthy words make Nines’ head blessedly and fully empty, wailing when Gavin picks up the pace and starts fucking him in earnest. “Yeah, yeah, yeah-”
The sound of skin meeting skin quickly fills the living room, broken only by Gavin’s deep groans of satisfaction and a little gasp from Nines every time he presses his hips forward harder and quicker. He can hear his thrusts getting wetter, the slide getting easier as Nines’ overworked body does everything it can.
“Fuck, fuck- that’s my good boy, Ni- Yeah, you like it rough like that?” he rambles, saying anything that comes to his sex-addled brain as Nines twitches and moans like he’s dying. “Yeah. You’re mine, you know that? All mine. Bet you wouldn’t do this for anyone else, would you? Fuck- yeah, good boy, my good boy, cum for me-”
“Just you.” Nines gasps, turning his head so he can look teary-eyed and beautiful over his shoulder. “Just yours, yeah, yes-” he hisses, and comes for the second time with a whisper of Gavin’s name he buries in one of the pillows.
Gavin can hear his cooling unit clearly now, the whir loud, Nines’ chest heaving with the effort of keeping his system from overheating. He’s merciful, and pulls out of him, despite the sad little noise Nines makes.
“Don’t want you to overheat, baby.” he explains, running careful hands up Nines’ back under the dress shirt.
“Wanted you in me.” the android replies weakly, and seems to have an idea, LED flickering as he slips back and off the arm of the couch to kneel, knees on either side of the mess he’s made. “Still want it.”
Gavin sucks in a breath, the sight of Nines on his knees like a punch to the gut. There’s tear tracks on his face, from being so deliciously overwhelmed, and Gavin takes his freckled chin gently in hand. He runs his thumb over that pretty mouth, which Nines eagerly opens to suck the digit inside with his tongue.
“You gonna be good? Want me to fuck your mouth, baby?” he asks, voice husky. Nines nods a little, as much as he can with Gavin’s now firm grip on his jaw. And the android leans backward, the back of his head pressed against the arm of the couch. Nowhere to go.
He drops his mouth open and tongue out, drooling a little around Gavin’s thumb, blue eyes half-lidded and glazed over when they meet his.
Gavin doesn’t need any more of an invitation.
He grips the base of his flushed-ruddy cock and guides it between Nines’ lips, letting out a breathy hiss when he presses forward. It’s so wet, just as slick and hot as his ass, but somehow even tighter when Nines closes his eyes and sucks. He moans, impatiently pressing forward until his nose meets the coarse curls of Gavin’s abdomen.
Gavin presses forward harder, forcing Nines’ head back against the arm of the couch, groaning loud when he feels the head of his cock slip down his throat.
“Oh that’s good, baby.” he breathes, grinding nice and slow, and Nines rumbles low and content at the praise. “Yeah, such a good boy. So hungry for it. You like it when I use you?”
Nines squeezes his eyes shut and moans, hand making slick sounds where he works at his overstimulated cock.
“Three times? Wow. Should do this more often. Bend you right over whenever I feel like it.” Gavin growls, rutting forward quicker into that wet heat. Nines moans louder, the vibrations and movement of his tongue driving Gavin closer.
“Fuck, yeah. Whenever I want. Bet you wouldn’t even need prep. Or I could just use your mouth. ‘Cause you’re about to come from just this, aren’t you?” He fantasizes aloud, eyes meeting Nines right as the blue of them rolls back into the android’s head.
Gavin pulls his hair, thrusting forward, letting out a drawn out groan as he fucks his release down the tight channel of his throat.
And Nines, cumming with him, just swallows and takes it all, seconds feeling like minutes as that perfect mouth wrings more and more out of him.
Weak-kneed and shaking, Gavin slips to sit down next to him, both of them desperately pulling in lungfuls of air to cool off and come down.
“You’re gonna bottom more often.” Gavin manages, voice hoarse.
“Yeah.” Nines answers, eyes flickering open, sounding startlingly put together. “You’ll have to work for it, next time.”
Gavin just laughs.
“I’m counting on that.”
