Keithley watched the woman struggle, trying to prevent the phallus from penetrating her flower. Her efforts were in vain, of course, her body held in place by the metal tentacles. It pushed into her pussy with its rubbery tip, embedding itself a few inches in her cunt.

Jag groaned as the thing pushed into her slightly. The first violation had been almost blocked from her sensations, so afraid was she… but this was something she was a little more used to… and that actually made it worse, the girl’s body reacting quite separately from her disgusted mind, her tunnel closing around the phallus tightly as it pushed into her sex lips.

Keithley watched as the redhead's body accepted the phallus, the aphrodisiac the insect had injected obviously still coursing through her veins. As her cunt clamped down on the metal cock, it vibrated pleasantly in her pussy.

More robotic tentacles appeared, rubbing at the student's lovely breasts. Their surface was shiny in the dim light, yet their touch was somehow soft as they caressed her tits.

The teenager groaned loudly as the thing within her sex began vibrating, the girl not understanding why this was happening. Was this guy just so sick that he got off on it? It didn’t seem that was the case…

Her thoughts were interrupted as more arms began feeling over the girl’s chest, rubbing and rolling the redhead’s firm breasts easily. Her tits responded almost instantly, the small nubs darkening and standing out against her large bosom.

The metal phallus vibrated harder now as it continued to shaft her. The tentacles at her chest were rubbing at her tits. Keithley watched the student as the tentacles violated her.

Jag groaned in fear and forced lust as the thing drove itself into her cunt faster and deeper with each passing second, her lips growing more and more wet, the sucking noise as it plunged through her folds starting to fill the room. Her chest bounced under it’s grasp, the things beginning to run over the teen’s tits experimentally, and all the time the sick pervert in the room above watched with a cold glare, like he wasn’t interested in the least.

Keithley pulled another lever, watching as the mechanical phallus withdrew from her pussy entirely, slick and shining faintly from her juices. Controlling its motions, Keithley directed the machine to her mouth, where its bulky tip pressed against her lips.

It pushed into her mouth, giving her a taste of her own juices as it entered her.

"Enjoy this while you can, student," said Keithley. "Once the experiment is over, we'll make sure the secret stays with us."

The redhead shuddered as the metal phallus slid out of her womanhood easily, one last, wet, sucking noise coming from her wet cunt as it withdrew. The metal arm made its way up her body, a couple drops of her nectar leaking onto her stomach and into the deep valley of her cleavage as approached the girl’s face. The tip found her lips, already open, although she slammed them shut as she felt the metal on them. It was easily able to press through the student’s full lips, however, and into her mouth.

She clenched her eyes shut in fear, not bothering to hide it now… she might not get out of this one…

The robotic shaft began to move in her mouth, vibrating as it slid into her mouth and giving her a taste of her own juices. It slid almost all the way out before plunging in again, fucking the redhead's mouth as the bug's aphrodisiac started to take greater effect...

Jag’s eyes fluttered slightly as the thing’s toxins began reaching her brain, making her… not dizzy… something…

The thing was actually starting to feel good as it plunged between her lips, Jag’s own juices dripping into her mouth, tasting too sweet… the girl’s nipples were perked up as her chest continued to rise and fall a little more than normal, her taut body hot and starting to gleam with sweat.

Her tongue found itself running over the length of the phallus experimentally, though she quickly stopped herself. What on earth was she doing?

The tentacles continued to play with her tits as the phallus shafted her mouth. Keithley watched as the chemical took effect in the student, still looking at her coolly.

The girl’s breasts began to burn with all new sensation, almost as if she had been fine up until now. It finally occurred to her that the thing that had bitten her might have poisoned her somehow… everything the machines were doing to her was feeling better and better, almost as if…

She fought to keep her mind hers, even as the things rolled and kneaded her firm mounds, the redhead’s tits fully erect under the cold metal.

Keithley continued to observe as the tentacles kneaded her erected mounds. The aphrodisiac had obviously affected her, and the tentacles were apparently doing a fine job. The mechanical cock in her mouth began to shaft her faster, fucking her mouth.

It took all her will, but Jag tried to twist her head away from the thing that was burrowing into her mouth like it was trying to pleasure itself. She knew if she didn’t do something now, her body would take her completely. Even as she thought it, her body bucked slightly in its restraints, pushing her breasts up towards the things playing with them.

As if sensing it beforehand, the metal phallus moved with her. It would not leave her mouth as it fucked the young student, as the tentacles played over her tits. It began to twitch slightly, a sign of what was soon to cum...
