...fuck her ass...

You now have the Queen before you, her back to your chest, and her tits in your hands. Even with her facing away, you know your roboslut has a pleased expression on her face. You remove a hand from her breast, reaching down to her ass as you squeeze her butt. You are pleased with a moan as you move your hand to the other cheek, squeezing it. You find it funny, you are reminded of when you were a kid and would perv with Barbie. You would explore her featureless body, but now, you have a life size anatomically correct Barbie, and its time to do something you've wanted to for a while. You hand begins to slide to the other cheek again, the queen emitting a coo sound, but before it reaches the other it stops, right between her cheeks as your fingers begin to slide between the peach globes. The queen's coos continue, obviously liking the gentle attention, but as you find what you were looking for, the coos disappear.

"What 'ARE' you doing?" She asks in a commanding tone, your reply is to push your finger inside. A gasp coming from Vexus, as your finger beginning to push into the impossibly tight asshole of the robot queen.

"God Vexus, I knew you were a tight ass, but I didn't think this tight…" You mutter as you pull your finger out, pushing the queen forward again. She was now on her hands and knees, her asshole and cunt exposed to you. "God, what a cute little asshole, I could just eat it out…" You say as you lean in, spreading her ass cheeks as you move your tongue down to the pin hole, barely visible.

You push your tongue to her asshole, struggling to push it in, you hands moving in a bit from her cheeks, to the rim of her asshole. You pull at each side, the little hole beginning to stretch, you suddenly push your tongue in, the queen squealing out in pleasure, programmed to love all forms of affection.

You spit in her asshole once more before getting up, confidant you have lubed the tight hole enough, and you bring your head to her asshole. "This is gonna feel great…" You mutter before you begin to push, your cock almost hurting as you strain against her impossibly tight ass, slowly, as queen Vexus moans in pain and pleasure, her sphincter gives way. At a dull pace you move inside, her asshole much like her mouth temperature controlled.

"Shall I release lubricant inside?" She pants out as you finally get in all the way.

You respond by starting to fuck her, you saliva as the lube you suddenly pull out, only to slam back in, giving her no time to adjust she cries out in pain and pleasure. Your cock now slides in and out of her, the peach hole moving with your cock, as you go out, the skin rising in the back, and then pushing in a bit as you trust back, enough like a real woman to gain your appreciation.

Vexus's hands grip your rug as you fuck her ass, drool running down her face as she tries to process all the sensations she is feeling. You continue fucking the tight asshole, the friction inside causing your orgasm to build quickly, and before you know it, you're about to cum. You suddenly reach down, grabbing her breasts as you pull her up falling back as the queen lands on you, your cock still deep in her ass.

As if on cue, she begins rolling her hips, your cock inside feeling a similar massage to the one you received in her mouth, you moan out. "Yes human, surrender to Queen Vexus of the cluster, feel the pleasure I can bring." Unable to take it, as, by Vexus's own doing, you cum deep in her asshole.

You pant hard as the queen continues moving her hips, your orgasm over, she begins to slowly ride, her asshole spreading a bit as it pulls from your cock, milking it for the last of your seed as it pulls off.

"Do you feel better then?" You ask, with a shit faced grin.

Vexus looked embarrassed, but nodded, the personality on this roboslut to perfect.
