Wait until Catherine comes back

Catherine returns from her break, carrying with her a strange canister.

"I'm back!" She calls into the room. "Hope you two are ready for testing!"

She lifts you up onto the cart and wheels you into the testing room. The first area is a small hallway with two doors. You enter the door on the right, and find yourself in a small room the size of a bathroom. There doesn't appear to be anything inside aside from a blank screen on the wall, but you can see another viewing window to your left. You're placed up against the wall in a sitting position. Your arms droop down limply at your sides. You feel like a barbie doll, limp and powerless.

"W-what's going to happen now?" You ask as Catherine turns to exit the room.

"Well, what do you think?" Catherine answers. "You're not that dumb of a robot, I'm sure you can figure it out.You ought to know by know what kind of place this is."

You felt your non-existent stomach drop. You should have known it was more sex.

Catherine exited the room, and you prepared for the worst. However, nothing happened. Two minutes passed, and then five. Only once eight minutes had passed, did Catherine appear behind the viewing window. She tapped on the glass to get your attention.

"Okay, Curly!" She called from behind the glass. Her voice was somewhat muffled. "We're gonna test out your functions now, to make sure you work properly!"

You closed your eyes and braced yourself.

"...So, first, I'm going to need you to preform some exercises to ensure your joints work properly. Okay? Let's have you get up first."

Suddenly, you feel your entire body move. You're being controlled manually, and no matter how hard you try, you can't stop it. It's as if you were ghost, observing a body through it's senses. Your arms push yourself off the ground rather smoothly, and you stand up and face the window. Even your eyes and mouth are moving on their own. You stare straight forward, and put your arms out by your sides.

You're completely at her whim.

"Okay, now let's have you do ten jumping jacks!"

"Huh?" You think to yourself. You jump in the air and lift your arms up. You do this ten more times, and then stand still with your arms at your sides.

"Fantastic. Okay, now rotate both arms for me in a circle..."

Your bend your body slightly to the left, and your right arm spins in a windmill fashion. The same then happens with your left arm.

"Okay, now lift your legs, one at a time..."

You do just that.

"This... this is just like some sort of doctor checkup..." You think to yourself. "It can't be this simple, can it?"

"Okay, now bend over and touch your toes."

You bend over.

However, you don't get back up. You stay in that position, your ass raised in the air. At first, you think that maybe you've locked up, but then you realize you've been too trusting of Catherine.

"Alright... Warm ups are complete. Now let's see you two in action."

The door opens to reveal Miku, standing with her hand on her hip, and a soft, robotic dick between her legs. She struts over to where you're bent over, and gives you a hearty slap on the ass.

"Hey there, big girl..." She says sultrily. "How 'bout we don't keep the good professor waiting and get this show on the road?"

She grabs your large, white ass, and starts to hotdog your butt.

"What's with her?! She must be being controlled, but... This is too lifelike! How is this possible?!"

Suddenly, your posture becomes far less stiff. Your eyes close halfway, your cheeks literally glow bright red, and you lick the corner of your mouth. You arch your back, and grind your ass against Miku's crotch.

"Huh?! What the hell?!" You think to yourself.

Your mouth suddenly opens on it's own, and from your lips, you hear your own voice speak out.

"C'mon then! Why don't you show me what you're made of! Stop teasing, and stick it in~!"

"No! No!" You think. "There must be some way to power through this! They can't just own us like this!"

But they could, and they did. You feel Miku's hands firmly grab your waist, and then next thing you know, her penis is jammed into your exhaust. You give an embarrassing moan, and stagger over to the window. You press your body up against the glass. With each thurst of Miku's dick, your boobs press up and squeak against the window. Your head is thrown back, and your tongue is drooping out. You can't even close your eyes, you have to embrace it.

"Ungh!" You moan "Oh, fuck! Deeper, Miku, Deeper! Use me and abuse me like the lifeless sex doll I am!"

You tilt your head forward and stare straight into the eyes of your creator. As you stand there, drooling like a hornball, she simply continues to take notes.

You feel Miku's dick inside of your artificial ass. Your butt is like a long rubber back, soaked to the brim with water and the juices your only organs create. Her dick feels like a penis, but is more like a dildo. Again and again, you feel it pound the sensors in your robo-butt, sending electronic signals to your brain and stimulating you.

"It's just mind over matter... Just mind over matter..." You think to yourself. "Just mind over matt-AAAAAGHH!"

Miku shoves her dick in as far as it will go, and you can feel it stretching the back of your colon. Your legs shudder, and Miku pulls the dick from your ass and cums on your back. You feel her warm semen dribble down your back, and you drop to the floor. Your legs splay across the ground, and you grab your breasts and squeeze them. You let out an electronic squeal, grab some of the semen with your fingers, and lap it up with your tongue.

"Mmm... Half of the entire canister was emptied..." Catherine muses to herself. "I'll have to go and get more semen from the Futas again. Maybe Miku can be on the receiving end... But for now, let's try out the vagina on Curly."

You crawl on your hands and knees to the opposite wall. You lay your back against the wall, and grab the undersides of your thighs. You lift your legs and spread them apart, exposing your puffy, silicon labia. You wiggle your eyebrows.

"Just... don't... think..." You think to yourself. Miku approaches you sexily. She bends down next to you, her hard dildo dick still dripping with cum.

"Wow, that looks so good... No! Can't think... like..."

Miku puts her arms under yours, and grabs you by the back. Slowly, she slips her long, hard dick into your surprisingly warm robo-vag. She penetrates you as far as it will go, and softly and lovingly begins to fuck you.

"..."

You give up. There was no point resisting. You loved Miku anyways, and secretly always wished for something like this. Maybe not as robots, but something similar all the same. You relaxed, and simply let yourself go.

You lay there fucking for ten whole minutes until the two of you orgasm and she fills you with her borrowed seed. As you lay there on the floor, cum dripping from your hole, Catherine tells you that autopilot mode was successful. Apparently, this took up 90% of the production time, as your body was being controlled by an A.I based off a permanently lusty woman. You were then turned to automatic mode, and allowed free control of your bodies for a few minutes.

Afterwards however, Miku was transported to Alex's room, and you were transported to the Futanari chambers. For an entire month, you were used as a sex doll. Never getting a break, as you didn't require sleep. Not only that, but after a day, your pleasure settings were set to maximum. Even the slightest touch of you skin would make you moan in ecstasy. You were in a state of permanent sexual bliss for 29 days.

When you were finally taken back to the lab, you were in awful shape. Your colon had been torn, your insides sloshed around with cum, four of your joints were gummed up with hardened cum, and your brain had been permanently scarred. You were now a true slut, just like Alex had wanted. Miku too had been used so much that her mind had been broken, and now the two of you lusted for sex, even when in automatic mode.

Both of you were then shipped to Akihabara in Tokyo, Japan, where you were used for entertainment. Since no one knew you were human, you were not considered sex slaves, but rather toys for pleasure, and were thus never liberated. However, you didn't mind. You spent your days happily getting dicks shoved into your three perfect holes. You were a cum dumpster. A sex doll for horny, lonely men to blow their loads into. Every day, you got more and more popular, and more and more people used you. Your mind broke more and more, and eventually, you were no longer required to be in autopilot. You willingly sucked off and fucked men and lesbians. Miku was the same. You even performed on stage at times, dancing on poles and swinging your silicon tits around like wrecking balls.

And the best part was, you never got tired of it. Every day was just as pleasurable as the day before. You never aged, and anytime you stopped working, you were sent back to get fixed. More and more transformed girls joined you, and soon, you were a selection in a booming business of sex bots. For 70 years you were fucked, until at last you were sold and replaced. You were then fucked by a man until your pleasure sensors broke, leaving you at maximum pleasure. Unable to repair you, you were discarded and buried in a junk heap. You lived in constant unimaginable bliss for years until at last your brain gave out and you ceased to function. Your eyes flickered and closed, and Curly the sex-bot was just a chunk of metal to be recycled.
