He does.

The moment you made your way over to recover the sponge, it was inevitable. All slippery and clumsy, you reach out for it and slip straight down to the ground after it, landing in a sprawl while cursing your power limitations. All things considered, you recover and get back up to your knees pretty quickly for somebody in your state, only to find yourself at waist height, staring right into your cellmates naked hips.

Fuck.

You look up at him while he looks down at you. A split second passes, before he reaches down and hooks both his arms under your armpits, lifting you clear off the floor, bare chest pressed against his. You struggle in his grip, but can barely twitch a motor.

"Get the fuck off me! I'll fucking kill you!"

You kick out at him, then turn to look for one of the guard robots. You see one, just impassively staring at you with no hint of a reaction forthcoming. You scream out in rage, thrashing about as much as you can in your diminished state. Your cellmate just squeezes you a little tighter, and takes a few steps over towards a table filled with dry towels. He sits on it, and twists you around in his grip, manhandling you like you're nothing more than a convenient sex toy for him.

"Let me go right now!"

He shifts his grip to your thighs, placing one powerful hand under each leg and forcefully opening your thighs with the quiet whir of resisting motors. You hyperventilate while looking down your body, seeing his erect cock mere inches away from your slit. You can't think of anything to get you out of this.

"Don't you put that thing in m-" You're cut off mid sentence as he just lifts you up, and drops you pussy first onto his length, spearing you to the core in one move. Your mouth goes wide as pain fills your mind, and you scream out, thrashing in place. He settles, adjusting his position go be more comfortable for himself, and wordlessly starts pumping you up and down, using you as a living sex toy. Every time he drops you onto his prick he stabs right into you, spiking pain between your legs. You have no idea how he finds this enjoyable.

He relentlessly pummels your cervix for minutes, before suddenly and wordlessly coming to a halt. You look backwards over your shoulder, making eye contact with him and continuing to struggle, when you feel him begin spilling his seed into you. You clench your teeth in anger and frustration, repeatedly striking him in the chest with your free hands. Over the next few seconds, seconds, the prisoner violating you pumps his sperm into your womb, and you can feel every drop. You try to free yourself, but his strong grip holds you down onto himself until he's finished fertilizing you.

Having filled you full to the point of overflowing around his cock, he pulls himself out, and throws you to the ground, before picking up his clothes, and casually walking out of the room like nothing out of the ordinary happened.

You're left on the floor, dribbling cum from between your thighs, and not sure what to do next. You eventually return to your cell, and sit on the bed, clutching your thighs until you eventually fall asleep. You can't even properly clean what he left in you out without going to the showers.
