Jag shook her head violently for a few more seconds before finally giving it up, allowing the thing to fuck her mouth as it wished, the girl unable to fight it, or so it seemed. She continued to try and fight down her urges even as it used her breasts to break her will, playing over the sensitive orbs. The thing in her mouth seemed to twitch, something she had felt before but… surely… it was a machine…?

After a few more seconds, the robotic phallus spasmed and released a load of fluid into the back of her throat. This substance was actually a fluid saturated with nanobots. It wasn't the full dosage she would receive; Jag would need about two or three more blasts of it.

The phallus withdrew, and another touched her anus.

Jag’s eyes went wide as it actually unleashed a load of what felt like cum in her mouth. The girl nearly choked, unprepared for such a thing, the thick liquid sliding down her throat as she was forced to swallow it.

She gasped as the thing finally withdrew from her mouth, still coughing and sputtering from its attack. The teen felt cold metal slide between her rear, and she began shaking her head, trying to protest, still sputtering and choking.

“N... not… there… not… that… please…” she coughed out.

The metal phallus, oblivious to her cries, entered her anus, pushing into her tight hole despite her protests.

Keithley's clinical face remained unchanged as he analyzed the redhead. He typed now on the keyboard, recording data.

The girl’s body contorted as it pushed through her cheeks and up into her backside, thrusting the whole of the girl’s body up in the process as it tried to push through her tight hole. She opened her mouth into a scream of pain as it stretched her, dying off into moans and sobs as she looked up at the man.

“How can you do this to another human? Please… just stop… let me go… I won’t tell anyone I swear… just stop this…” she begged, scared into submission.

"It's too late for that now, Miss Alexandra," Keithley told the redhead. "It's a shame, but we can't stop now. Besides, there's no other way to ensure you'll stay silent."

The tentacles continued to rub her tits as the phallus raped Jag's tight rear.

“No! Please… ugh… I’ll keep quiet… I’ll leave the school… whatever you want… I could… do something for you…” she said, hoping her bare, displayed form might arouse him at least a little. Still, she could only writhe and buck as the thing pushed into her tight rear relentlessly, fucking her without mercy. The things at her breasts continued to manipulate the firm orbs, the teen’s chest shining slightly with sweat now.

Keithley looked at the woman with an impassionate gaze. "Dear student, you don't seem to understand: I don't care. And here's a little secret for you, since you're not going to matter much longer: the only way to leave the school is to be enslaved by the aliens."

All the while the tentacles worked on Jag's sensitive body, massaging her tits, squeezing lightly at her nipples as the metal cock pumped into her ass further and further with each thrust.

His words hit her like a semi truck. There wasn’t any hope after all… everything she’d done to better herself, to try and make it out of this place… was for nothing?

All her will gone, she simply lay in the clutches of the machines, getting raped in her tight ass by the thing, her chest a playground for the metal fingers of the scientist’s machine. She clenched her eyes shut and wished it could all just be over, despite that it apparently would be very soon.

Another metal tentacle split open at the end, revealing a phallus similar to the one that was raping the student currently. This one pressed against her vagina, its surface brushing her clit as it rubbed her pussy. It continued to stroke her sex-lips and clit as the other metal device shafted the redhead's rear.

The girl whimpered as she felt another tentacle probing at her cunt lips, slipping between them almost teasingly, not pushing all the way through into the teen yet. The aphrodisiac, unbeknownst to Jag, was having its effect. Though she was keeping her mind for now, everything, even the rubbing of the metal over her clit, was being magnified in her body, making her shudder and gasp as it probed at her. Even the one in her ass, usually something absolutely repulsive to her, was bearable, at least as far as her body was concerned. The inhuman sounds of the machinery filled her ears as she was raped by it.

The tentacles continued to pleasure Jag's heaving breasts as Keithley watched. The metal cock in her pussy slowly pushed itself in further, hunting her "G" spot as it pressed into her cunt. Another metal tentacle emerged to stroke her clit now, rubbing the excitable little nub.

The girl’s thoughts were forced back to her situation as the machines began to tease at her clit, the one below it finally pushing all the way into her. The teen threw her head back into a long cry of forced lust as it penetrated her yet again, feeling even more than the first time, somehow… her breasts burning with sensations as it played with them.

“Whuh… nnnnngaaah… why… are you… doing this to me?” she got out, sweat now covering the entirety of her body, making it shine in the dim light.

"Because, my dear," said Keithley, but his next words were drowned out to Jag as the mechanical cock in her anus let out a high-pitched whine and released a heavy dose of its fluid into her ass. The second it withdrew, the metallic phallus in her quim began to rape the student faster, penetrating her tight hole again and again.

Jag’s eyes nearly rolled back in her head as the thing in her ass “came” in her, releasing the same kind of fluid into her tight hole that had been forced down her throat. It quickly withdrew with an audible pop, and almost as if to make up for it, the one plunging into her sex drove itself through her lips faster and faster, her only remaining hole that had yet to be filled with it’s strange secretions.
