The other girl let out a cry as the paddle struck her again, she looked at you, defeat apparent in her eyes.
The toy buzzed, twisting slowly inside you, and you squirmed as the first stroke of the paddle struck you. You jolted forward, grunting and feeling the pain spread across your ass. Subject forty-seven let out a whimper and the paddle that rested on your ass pulled back again, you could see that behind her the same thing was happening.
In a synchronised movement both paddles came down together, the harsh sting combining with the intense pleasure of the vibrator inside you. As the paddle struck you again you felt a shiver run over your skin, your mind going fuzzy. You could see the other girl opposite you, but nothing was really registering, only the thuds, the intense heat burning on your ass, and the pleasure of the toy mixing into a concoction of pleasure and pain that you didn’t quite know how you felt about.
The machine’s voice sounded over the speaker system, crisp as ever, “Well well subject fourteen, it seems you’re enjoying this a little more than you should be, I’ll certainly be adding that to my files. Now, you will both count the remainder of the strikes.”
The paddles came down once again and subject forty-seven gasped “one.” sucking in air. You moaned involuntarily as the paddle struck you “one,” you tried to keep your voice level but it wavered as you spoke, you felt your nipples tingling, and you couldn’t tell if it was the toy inside you or the paddle that was hitting you that was getting you so riled up. You were beginning to suspect it was a combination of both.
“Two,” the other girl said quietly, her head down, as the paddle made another swing, and you said the same.
Three was particularly hard, or maybe it was just that your ass was getting more tender now, and you both shouted out in unison.
As the machine pulled back for another stroke you heard a moan from next to you and you remembered how many other people were trapped here against their will, forced to take part in whatever twisted experiments this machine wanted.
“Four!” subject forty-seven near shouted as she was struck again. You whimpered at the stroke, your body taking a second to comprehend it.
“Non compliance!” The machine said loudly, and you felt three hard swift strokes across your ass.
“Ow!” you cried out in pain, feeling your ass burning red hot. You wiggled it in the air, trying to lessen the pain, but it was no good.
“I guess we’ll just have to start over again.” The Machine spoke coldly.
“No, n-no please!” subject forty-seven begged, and she looked desperately at you.
“Pay more attention. Start from one.” The voice commanded. You had no choice but to comply.
Focus, you thought to yourself, I need to do what it tells me, if only for her sake. You looked at the girl as the first stroke hit. “One,” you spat out through gritted teeth, each was hurting more than the last, but you were clearly enjoying it more than she was.
You closed your eyes and focused on counting, taking deep breaths. As the numbers got higher your ass got more and more sensitive, you could only imagine what the bruises would be like.
“Nineteen,” you both gasped, you could feel the heat coming from where the paddle had hit just moments ago.
The final smack was the hardest of all and you both let a cry of shock “twenty!” you fell forward, resting your full weight on the supports that held you in place.
“Please…” begged subject forty-seven from across the aisle.
“Have you learnt your lesson subject fourteen?” The voice asked as you gasped for air.
“Yes, yes I won’t do it again, I’m sorry!” you stammered a little as you talked, the world around you starting to come back into focus.
The clamps loosened and metal arms plucked you like a rag doll, you were too tired and completely powerless to resist as it pulled you off, another opening appearing from nowhere which you were promptly taken through. “You will wait in the holding cell until I decide what further punishment you will receive,” the machine said robotically as it deposited you in a cell somewhere deep inside the complex.
You squinted in the relative brightness, away from the darkness of the punishment room. The cell where you’d been deposited was a lot smaller than the one you’d been taken from, about the size of two double beds. It was padded the whole way round and on the wall was the same camera that had looked down upon you in the bigger cell. In the corner was subject forty-seven, turned away from you, pressed into the wall. You could see how red her ass was and given how hot your own butt felt you guessed yours must look much the same. You moved quickly over to her and took her in your arms, she rolled over exhausted and looked up at you, not saying anything. You took her head in your arms holding her and supporting her, stroking her hair. “It’s ok, it’s over, I’m sorry.”
She smiled weakly, reaching up to stroke your face, “It’s ok, it’s not your fault,” she slumped back down on top of you, closing her eyes. You stroked her hair for several minutes as the burning hot sensation that ran across your ass slowly faded into a duller thumping pain.
You heard a magnetic clunk and the cell door swung open, the robotic arms that had so easily manhandled you before sweeping in. They quickly pinned you in place and a strange metal device suddenly appeared from seemingly nowhere. You squirmed as the arms fastened it around your waist, your arms held firmly out of interference distance. You felt the belt tightening as a strap slid up between your legs, fastening in place.
The arms released you and you slumped against the cell wall. “What is this thing?” you tugged at the device, but it was no use, it was firmly attached and there was no way for you to get it off.
“For the second part of your punishment you will wear this reverse chastity belt,” you felt a buzzing from inside the device and realised with horror what you were wearing. “You will be edged and forced to orgasm at my will. And I’ve gotten *very* good at reading body signals, so you’d better believe that I know when you’re close.” The machine said, and you swore you could sense a hint of glee in its voice.
You felt something press against your asshole and you let out a gasp as a plug slid slowly inside you, coming to its resting place inside you. A dildo pressed against the entrance to your pussy a few seconds later and you shuffled in the belt, moaning as it started to gently buzz. You realised just how wet you were as the dildo slid inside you effortlessly. Against your clit you felt the belt moving, pressing gently against it and then slowly beginning to buzz, the vibrations becoming more intense as the dildo began to slide in and out of you. You felt your heart racing as the thrusts continued, and you felt yourself getting closer to cuming. As you came to the edge everything abruptly stopped.
“No!” you cried out, trying to reach down to help yourself get there. but it was no good, the belt was too tight. “Fuck!” you muttered. As the sensation began to fade away you felt everything whir back into life and your heart skipped a beat, it didn’t take long for you to feel the need to cum again, this time you got so close you were sure the machine was going to let you cum, but again the buzzing and thrusting stopped and you let out a cry.
As the toys started up once more you took a deep breath, you lay down on the padded floor, eyes closed, trying to focus on orgasming, on pushing yourself over the edge. You started playing with your nipples, gently twisting them, your breaths were shorter now and your knees pushed closer together, your back arching as the machine brought you there once again, this time it was different, instead of shutting off completely the machine expertly dropped and increased the intensity, keeping you hanging on the edge unable to go over. It was agonizing bliss.
“Please…” you moaned, your head slumping, orgasm the only thing you could think of.
“I will let you cum once you make subject forty-seven cum.” the voice said matter of factly. You looked up at the girl you shared a cell with desperately, crawling over to her. She laughed and opened her legs.
“That bad?” she said, but you weren’t listening, all you cared about was making her cum. You crawled in closer to her desperately, your ass sticking up in the air. You’d never given oral to a girl before but you knew what you liked and you tried as best as you could to emulate that on her, licking and sucking her clit like your life depended upon it. She lay back playing with her nipples, “hmm, don’t stop, just like that,” you carried on, the feeling of being so close to the edge of orgasm was almost to much to take, she started to breathe more heavily and you felt her spasm as she came, twitching as her thighs tightened around you.
Suddenly the toys inside you buzzed up a gear and you felt an orgasm flooding through you. It was the most powerful orgasm you’d ever had and you fell to the floor, curling into a ball as wave after wave of pleasure flooded over you, your thigh muscles tensing as you came, moaning and shaking with every new pulse of pleasure. Your toes curled as the machine buzzed even harder and you screamed as it forced you to orgasm a second time, the intensity of this second orgasm was too much and your mind went blank, your whole world reduced to a pinprick of light, before exploding back into reality with another wave of pleasure.
As the buzzing slowly died down you began to feel your senses returning and you realised you were laying on the floor curled up, twitches of pleasure still coursing through you as your ass burned for the spanks. You rolled over and gazed up at the other girl who sat looking on, touching herself. You tried to speak but no words came out. You closed your eyes, waiting for the world to stop spinning, and you fell into a deep, dreamless sleep.
