The machine paused for a moment, perhaps confused, you though, or perhaps just curious. The hands began to cautiously brush against your skin again, but they weren’t as lustful this time, they were waiting. Waiting for what would happen next. Waiting for whatever the machine wanted.
“Well, that is most… unusual…” The metallic voice paused, a slight hint of uncertainty creeping into it for just a brief second “Only one other subject responded in this way to my tests, and she’s… well… let’s just say for the time being her time is ‘otherwise occupied’… perhaps I will introduce you two sometime?” you detected a sneer now, and you wondered what the machine had in store for you. What the fate of the other girl had been. These thoughts soon disappeared as you suddenly realised how tired your orgasms had made you.
A small metallic arm firmly lifted you head to face a pinhole camera that appeared in front of you, and blue light broke out of the ceiling, scanning your body. After a few seconds the light retracted and then blinked out.
“Well subject 14, your medical scan seems fine, and you don’t seem to need lube this time” you suddenly realised just how wet you were as the hands started to wonder to your breasts again, stoking them and squeezing them, whilst more girls ran their fingers idly up and down the inside of your thighs, stopping just short of touching you, driving you crazy.
“Fuck” you whisper under your breath, your heart starting to beat faster again. It shouldn’t feel so good but it did. The constant touching and attention was driving you wild. You were here against your will, powerless to stop a sentient machine from doing whatever twisted sexually deviant things it wanted to you, whilst a room of women looked on and touched you. You had no control over your foreseeable future, though by the looks of it, that was being some kind of sex slave for this insane machine.
God you were so turned on.
You felt high as a kite as the machine manipulated the position of your body, the hands touching you adjusting as you moved but never breaking contact. The machine stopped buzzing, and you were in position. You were still held in the same restraints, all the way past your elbows and up to your knees, unable to move.
You were on your knees, legs a comfortable distance apart, your chest was parallel to the floor, but your arms were held backwards by the restraints in V shape, level with your hips. One of the girls sat in front of you. Your head hung down and she ran her fingers up through your hair from your neck, tightly grabbing as close to the roots as possible. She pulled your head up, and you didn’t resist. She shuffled closer, supporting your head on her shoulder and running the fingers of her other hand gently over the bumps on your spine.
“Thank you” you said, twisting a little and looking into the girl’s eyes, she was very beautiful and she smiled slightly at you.
“You’re going to need it” She whispered softly, kissing your head and moving you back into position.
You jumped a little as the machine spoke again, “Beginning test 3 – simulated feelers”.
You heard the sound of metal scraping on metal, as two holes in the floor opened up behind you. You felt a twinge of fear as you felt something moving behind you, and the girl who was holding your head held you tighter.
“Remember” said the voice “You wanted this.”
“W…What exactly is, this?” You said, feeling your fear mix with growing arousal, you tried to turn your head in vain to see what was going on behind you. You felt something unusual but not unpleasant begin to slowly slide up your back, the hands parting to let it progress, it felt soft, but hard at the same time, like someone’s arm.
When the sensation reached the base of your neck it split off into two parts, and something strange appeared on each side of her head. It looked like a dildo, but certainly no dildo you had ever seen before.
“Do you like them?” The voice said, almost proud of what it was showing you “highly engineered silicone, I call them ‘feelers’. I designed them to help me experience something similar to what you do, so I can measure it, feel it, know what it’s like to be human. But, you see, there’s one thing, I need the maximum possible surface area for the best sensation” the feeler flexed and little ridges ran up and down the outside of the material.
The feelers retracted, pulling away behind you, and one of the girls began playing with your exposed clit as the head of the feeler pressed against you.
You gasped as the feeler pushed inside you, it slid in surprisingly easy, the substance had a lot of give but you still arched your back as it pressed deeper inside you.
“Fuuuck” you moaned in pleasure, trying to pull your knees together instinctively, the restraints not letting you. It began to slide slowly back and forward, the ridges always rippling in the opposite direction to the thrust. It felt incredible. The machine continued, getting rhythmically faster as you felt everything else melt away. It was vibrating inside you now and you were so close to cumming. One of the girls pinched your nipples and you twitched, letting out a breath you didn’t realise you had been holding. She pinched again, twisting and holding this time, and as the machine pulled outwards you came.
You began to shake as the machine thrust inside you again, stopping at the perfect depth, still vibrating.
“Oh god. Oh god. Oh godddd” You mumbled into your supporters’ shoulder and your whole body shook for a second time as the next wave struck.
Suddenly the vibrations stopped. The toy, if you could call it that, sat inside you, and you caught a breath. Was that it? Was it over?
After a moment too long, the arm began to move again, except the head stayed put deep inside you, it felt more like something was moving further back, like the machine was making an adjustment.
Suddenly you felt the other head sliding over your ass and you remembered that this thing had two parts. It didn’t take a genius to guess where the other one was going…
As it slid into your ass you were completely paralysed. Your mouth hung open, and you no longer had control of what little parts of your body you had been left in control of. As the feeler reached the same depth as its counterpart in your pussy you felt the two gently expand inside of you.
You’d never felt so full in your life, and you didn’t want anything else but be this full. The toy in your ass began to slide in and out, and you nearly came from the first two strokes, just as the part in your ass was thrusting in, the one in your pussy began to slide out. You could feel how wet you were. Soon they were fucking you one after the other, you were constantly been fucked by one of the toys. This drove you crazy and you were hanging on the edge, unable to get over.
Orgasm was so agonisingly close and yet so incredibly far away. You tensed as the strokes continued rhythmically, the toys rubbing against each other through the wall of your pussy, the constantly evolving and buzzing ridges rubbing your g-spot with agonising perfection.
“Please” You whispered.
The machine seemed to respond, one of the toys breaking it’s pattern, slowly synchronising with the other so that they were thrusting together. The girl playing with your clit started rubbing in circles, this, alongside the continuous rhythmic thrusts sent you into a spasm, your legs pulled on the restraints and your body shook over and over, the machine relentless in its thrusts. You came harder than you’d ever cum before, your whole body flooded with emotions, a strange, overwhelming calm flooding through you, as if nothing else mattered.
After a moment you felt the thrusts stop and the arms retract, falling out of you, leaving you empty. You were still in a blur, limp, unsure of what was up and what was down.
“Clean” said the voice, someone what bringing to your senses, and you looked up to see the head of the toy soaked in your juices hovering infront of your face. Christ, you hadn’t realised how wet you had been. Instinctively you licked the toy, tasting yourself off its surface. As you finished licking yourself off the machine, your body began to move involuntarily as you were forced gently away by the massive mechanism that had held you in place since your examination hours earlier.
“I think that’s enough”. This time you didn’t protest. You struggled to make sense of your surroundings as you were lifted into the air, the faces of the girls in the cell below fading away as you were taken to god knows where.
The machine set you down in a small barred area, and suddenly you were released from the restraints. In shock you fell against the bars, your body unable to support your weight after so many hours.
“Good night Subject 14” The machine’s voice faded away as the mechanism that had held you folded up and retracted into the cavern “I’ll see you again tomorrow”
Suddenly the bars swung open, and you fell into a larger area, several pairs of hands catching you.
“Poor thing” Said a woman’s voice.
“New subject” said another “She looks tired. Set her down so she can rest.”
You felt yourself being lowered gently to the floor, which was made of some kind of soft padding. You looked up at the women, suddenly realising how utterly utterly exhausted you were “Thank you” You breathed, and your world went black.
