The girl looked about as quietly as possible, her eyes wide. What on earth was in here with her?! Invertebrates? What did he mean by that?

Her chest leaped up and down, large breasts bouncing just barely as her loud breathing was heard through the room. She didn’t know what he had planned but this situation could lead to nothing good for her.

Suddenly something touched against Jag's thigh. It was shiny and hard as it rubbed against her bare skin. It smelled of dust as its hard exoskeleton brushed her leg.

Keithley looked down at her. "Looks like one's found you already," he said, continuing to make notes.

The girl shivered in her restraints, eyes going even wider as something brushed against her curved thighs, the firm flesh there seeming to tremble as something passed over it. Something glinted between her legs as it moved past her. She shakes her head back and forth quickly, hoping to god that it gets through on some level to the man, the sight of the young, nude girl maybe setting off some lost sense of morality.

The creature touched against the inside of her thighs with its pincer-like front legs. It gripped her thighs to heave its upper portion against her crotch. Leaning against her spread legs, the massive insect touched against her breasts with its feathered antennae.

"Have fun," said Keithley. "I'm sure the others will get their turn soon..."

Jag wriggled and finally screamed past her tapped mouth as it began to crawl up her… she might be brave enough to take on most of the monsters on the island, but if there was one thing that terrified her, it was bugs. She began to shake wildly, trying to throw it off, it’s disgusting appendages crawling up her legs, feelers feeling at her heaving chest. The girl’s eyes were wide with as she continued to thrash, desperate to get it off her.

The giant arthropod's pincers kept a firm grip on her thighs, which were already moderately apart due to the robotic tentacles holding her. The massive bug suddenly placed its head over her stomach, and lightly nipped her. Its mandibles injected her with their venom, an aphrodisiac that had to be administered to the blood.

The creature reared back again, screeching somewhat. Its pincers pushed her legs further apart as it brought its abdomen closer to her crotch. Jag could practically feel the invertebrate's chitinous armor shifting against her.

Jag yelped past the tape, tears finding their way down her face now from fear. The small nip at her stomach had hurt more than she would have guessed. Worst though, was what it seemed to be doing… spreading her legs even wider, dragging its body over her bare crotch, seeming interesting in her mound. Muffled sounds came from her gagged mouth, seeming to plead with the scientist to not let this happen.

The scientist ignored her cries, watching the student cry and struggle. As the beast mounted her, its insectoid erection pressed against the entrance to her sex. It made a clacking sound from its mandibles, followed by a low screech as it pushed into her.

Jag continued to thrash, her movements becoming even more frantic as she felt it press something against her sex, holding it against her bare slit for a few moments before pressing into her. The girl screamed in hysteria as tears streamed from her eyes, going insane with fear.

The insect pressed its member deep inside Jag's pussy, driving deep into her slit with its bulk. It pumped into the helpless student, fucking her with its erect organ. This only lasted shortly, however. Soon the bug's cock began to quiver, and after a few moments, the alien invertebrate spurted a jet of semen deep into her cunt.

Jag was surrounded by the other bugs as the first withdrew. It settled its body on the ground, and another gripped her thighs to take its place. A beeping sounded in the distance.

Keithley checked his watch. "You're lucky," he said to Jag. "Feeding time." The massive creatures scuttled away as the lights brightened, moving into a tube in the wall, where they turned a corner and disappeared.

Jag continued to scream hysterically, until her throat hurt and her lungs burned for air. She could feel it thrusting deep inside her, no worse than any monsters that had done the same, but at the same time driving her insane. It only got worse as the thing released into her, its disgusting stream of seed pushing deep inside the teen. Even as it dismounted from her, more and more gathered around her, and the hapless student simply cried, groaning in hysteria.

Something beeped nearby and the bugs seemed to leave… causing Jag to break into a further torrent of tears. She had never been so scared in her life…

Keithley made more notes as he observed the crying student. He pulled a lever, and more robotic tentacles emerged from the floor. One situated between her legs resembled a phallus more than a tentacle, and the sides of it were coated in rubber.

Jag suddenly felt the tape removed from her mouth by one of the tentacles. It held the tape briefly in front of the redhead, waving it at her before throwing it aside.

Jag gasped and yelped at the same time as the tape was ripped from her lips, her sobs slightly louder now that the gag had been removed. “Let me go… please…” she cried, still so terrified she had her eyes clenched shut, not even seeing the new menace that was threatening her womanhood between her spread thighs, some of the insectoid’s cum dripping from her cunt quickly.

Keithley looked at her. "Sorry. That's no longer an option. You know too much. You must be silenced."

His voice was cold as he spake, uncaring and clinical. The phallus pressed against her bare sex now.

The girl’s eyes went wide as she felt rubber on her sex lips, a familiar shape and pressure that she knew all too well. She pulled at the machines again, although not nearly as fervently as she had before, not driven quite as much by her irrational phobias this time, but by a more normal fear, one that, she had sadly become far too accustomed to on the island.
