A/N:If you know Detroit become human then it's like that. If not just know deviant means a robot/Android that has human emotions. That's  all, oh and also I was told to put a warning that this is a trans Keith fic so yeah. Here's that warning y'all wanted! So I suggest you skip this if you don't wanna read about trans Keith.

-----------------------

"I've wanted to do this for so long." A low rumble in a light voice. Keith is surprised to note that it's the first time the android has spoken.

"Take control," he continues, "The way I was made to be taken control of."

Keith shudders. How can just a few words be so terrifying and titillating at the same time?

"Why me?" Keith questions, and it's not a gripe, but a soft expression of curiosity.

Lance's eyes jump back up to his. "Because," He presses closer, "You're the prettiest I've ever had."

There's a split second of Lance breathing against his mouth, and then Keith is moaning into another kiss as Lance speeds up his thrusts. By now the discomfort of overstimulation has mostly subsided, leaving only a too-hot bliss in its wake.

Lance is fucking him hard now, with the sort of relentless speed and strength only a robot could be capable of. Keith's legs slip down from smooth shoulders, quickly replaced by his hands as he scrabbles for purchase, the backs of his knees now cradled in the bend of Lance's elbows. The change in weight distribution doesn't seem to bother Lance at all, as he continues fucking Keith into the wall like it's the easiest, and yet, best thing he's ever done in his life. Keith is hardly sure of what noises he's making anymore, only that there's a cock driving into his pussy more times per second than he can count and a pair of lips drinking in his every sound.

The pressure builds, and with it a sense of anticipation. Keith isn't sure what's going to happen after he cums, and it makes him uncertain, wary even, but those feelings only seem to drive him towards the edge faster.

Several things happen at once. Lance hoists Keith up, brings his arm around Keith's bottom to free his other hand. The motion breaks the union of their mouths, and Lance's finds itself now level with Keith's neck, which it nips. Additionally, that freed hand comes up to brazenly grope Keith's chest, twisting a nipple. The angle of penetration changes, but the pace doesn't falter for a moment, nor does the depth of his thrusts subside.

It's all Keith can take. Not a moment later, he's cumming around Lance's cock, winding himself so tight that the appendage feels bigger inside of him. Lance doesn't stop or slow down, fucking him through it until he perceives it's over, persisting in his ministrations on Keith's neck and chest all the while. However, he pulls out all at once as soon as he perceives that Keith has come down, giving him no time at all to pant through the aftershocks. Keith hardly processes Lance gathering him closer into his arms before he's being thrown onto the bed, hissing at the sensation of being pulled out of so suddenly.

And then there are hands back on his waist, and he's being flipped over onto his stomach, then pulled up onto his knees. He makes a move to get up on his hands and knees, maybe even stand up, but Lance is shoving him face down into the bedding by the shoulder blades as soon as he gets his hands planted.

The head of Lance's cock is prodding at his entrance again, and oh god, it burns. Lance sinks in with a groan of pleasure and without hesitation, pulling Keith's hips flush to his. Keith's cunt is used and raw and the sensation of it being penetrated again, while notcompletely painful, is enough to make him cry out.

"Fuck! That hurts, asshole!"

"Shut up," Lance rebuts, already pounding away. It's the same relentless pace from before, and it causes tears to prick in his eyes. He's thinking he might try to tell him to stop, or scramble away, but before he can even finish the thought, there are fingers prodding around the hood of his growth, and that definitely feels good. The added pleasure causes his muscles to relax a bit, which soothes the friction of Lance's cock, and Keith can just begin to appreciate how wet he actually is, how rhythmic Lance's unending thrusts. His slick has soaked into the hems of his fishnets and stickily coats his thighs. It creates an obscene, sultry sound every time Lance drives in deep.

It's not long before Keith is moaning again, begrudgingly on board with their goings-on once more. There's no denying that, as sadistic as he may be, the android isgood at sex. It's what he what made for, after all.

The viscous wetness between his legs certainly doesn't go unnoticed by Lance, either. Those fingers that had been jerking his cock trail away, to which Keith squirms in complaint. They end up at the elastic bands that circle his thighs right under the swell of his ass. The fishnets. The tips of them dip underneath the bands, linger, then snap them against Keith's slick, sensitive inner thighs. Keith emits a high-pitched gasp in kind.

"You're so wet, I could fuck your thighs without anything else..." Another snap. Another dirty, slutty gasp. "You like that, huh..."

Lance's other hand smooths over Keith's ass to join the first between his thighs, touching at the slick. He coats his fingers in it, rubs up against Keith's pussy lips to collect more, until his hands are completely coated. Rubbing at his sensitive thighs causes Keith to shudder and bury his face in the sheets. Then, Lance draws those hands up over Keith's ass cheeks, smearing his cum over them. He rubs and massages it all over the globes of Keith's ass, which are bouncing at every thrust angled in such a way that makes Keith want to stay on Lance's cock forever. Still, whatever it is that Lance is doing needs to be addressed.

"W-what - ahn - what are you doing that for?" Keith demands, flustered

"Just for my own pleasure," Lance answers nonchalantly. He's nearly coated Keith's ass in his own release now, essentially, well. Essentially oiling him up, Keith supposes. Again, what a perverted robot.

"Fucking - god, you suck," Keith bites back

There's a resounding crack that Keith hears before he processes what has caused it: a harsh slap to his now wet ass. Over his tortured moan, Keith can hear Lance saying, "That's an idea. Now, didn't I tell you to shut up?" Lance spanks him again for good measure, then assumes an iron grip on his hips to fuck him harder and faster.

"Grabbing onto these hips makes it so easy to fuck you. You were made for this, Keith."

Keith's body flushes at those words, but he keeps his mouth shut, enjoying the continuous pounds of Lance's hard cock into his pussy accompanied by the tingles of overstimulation. He's being fucked utterly silly, Lance's strength allowing him to force him up and down on his cock as if he weighs no more than a blowup doll. He can feel his ass bouncing every time it collides Lance's pelvis, something that certainly doesn't go unnoticed by the android, either.

"Your ass looks so cute bouncing on my cock like this. I could fuck you forever." There's a short pause, and then Lance continues, "I actually could, you know?"

Keith only mewls in response, eyes rolling back in his head at the feeling of Lance's hands on his hips, the way his cock rubs against the raw walls of his pussy. "Enough blue blood and I could sustain this for hours."

A pleased sigh from behind him. "Hmm, but I'd rather just give in... to the pleasure... you need to rest, anyways..."

Lance's thrusts become ever so slightly more erratic, what Keith assumes is meant to be a simulation of his body gearing up for orgasm. Keith moans into the sheets, presses his ass back against the android in anticipation. He's not expecting it when Lance pipes up again, "Let me just... I want to feel you cum around my cock one last time..."

Lance gives up some of his leverage on Keith's body to move one hand down between his legs once again, fondling the erect growth there. It brings Keith's pleasure to a whole new level, enough so that his knees get weak and he slumps further into the mattress. There's a moment where Lance isn't able to shove himself quite as deep because of it, but then he's leaning over Keith and driving in even deeper than before. It brings Keith right to the brink of his third orgasm, the fingers massaging his dick, the cock massaging his insides, and the feel of Lance's body heat over his back... plus, like, a million other feelings that Keith can't put a name to. The intensity, the humiliation of Lance's words... They replay in Keith's head like a broken record. If anything has stayed the same from when they first started fucking, Lance's mouth wrapped around his dick, it's that he feels utterly desired...

Suddenly he realizes that that same mouth is now latched onto his earlobe, hot lips and sharp teeth being what finally drives him over the edge. He thinks that he must cry Lance's name but he can't be sure, not with the white-hot surge of pleasure that overtakes him, not with the faint awareness of Lance's own moan behind him, not with the distant awareness of the release of artificial seminal fluid into him. Lance stays seated in deep for several minutes as the both of them (mostly Keith) drift slowly down from their climaxes, Keith completely boneless and collapsed into the mattress. Lance slips out of him all at once, and Keith's cock gives one last valiant throb at the aching sensation before softening. With a few more deep breaths, Keith is able to roll onto his side just in time to see Lance plopping down next to him.

"Get some rest. I'm going to take you again soon," is all the android says before powering down into a sleep-like state. His breath evens out, and Keith should be less surprised to note that he looks peaceful, endearing even.

A deviant android, Keith ponders. Huh. Would the agency even want him back? Wouldn't be very good for business, if he was meant to be submissive and prefers dominance...

The android's breathing causes a lock of hair to shift away from his temple, displaying the LED that had previously been hidden for a more realistic feel. Blue. The same color as his eyes.

Maybe I'll keep him.
