Kim is bred again...

Kim panted out of breath. She had lost count of the orgasms **** on her helpless body as the multiple larvae squirmed their way out of her womb and into the world. The last one was still suckling at her left breast while the others had seemed to squirm away, she had no doubt they were headed to the large lake where she had been milked before.

The last one detached and slide down the stone table to join his siblings, leaving Kim to asses the damage done to her body. She could see her tits had swollen to at least double the original ample size but after being drained of milk were now deflated laying more flat on her chest. She could see her stomach had shrunken down but stretch marks stretched across her formerly tight stomach. Her own cum was mixed with the birthing fluid of the creatures on her inner thighs and a large pool of it covered the table between her legs

She could tell something inside her had changed. She couldn't get the image of tentacles **** and breeding her again and again out of her mind. Her body was craving the larvae suckling at her breasts. She wanted more, she needed more. She grinded her hips in the air against nothing as the aphrodisiac venom coursed through her.

The doctor had selected a different creature from his various collection to mate with Kim a second time. Using thick rubber gloves he carried the 4' long centipede in both hands as he laid it on the table between Kim's spread and bound legs. He returned to his notes to record the new changes to Kim's body from the previous breeding.

The centipede slithered up the inside of Kim's left thigh and worked its way to her spread pussy lips. It could sense the heat and arousal emanating from her wet pouty lips. It slid further up her stomach until it's head rested above her navel. It's lower half slid into position between her legs and wrapping under her ass, resting between her cheeks.

Kim could see and feel the creatures tiny legs pulling and teasing her sensitive flesh. She felt something thick and hard in the middle of the creature press against her wet folds. She wanted so badly for the creature to penetrate and breed her but she began shaking her head. "No.... No.... Not again.... Not so soon...." She managed to say between panting breaths.

The doctor loomed over her. "Yes. Yes my dear. Again and again you will live out this fate. Until at last your body expires."

She moaned deeply as she felt the creatures member penetrate her pussy. It began sliding out and pushing deep as Kim writhed and moaned with each thrust. The aphrodisiac pushed her over the edge as she came again and again on the creatures cock.

"Subject Kim Williams will now be designated as Subject K-14, the 14th such test subject I have used. K-14's breasts have increased in size by 120%, lactating quite easily and rapidly filling with milk after being drained. K-14 was previously bred with 21 native larvae from a syphropod and is currently mating with the native gargantuan centipede. K-14 has had over 50 doses of the larvae's venom and I suspect may become dependent on its effects. The result has driven her into an animalistic form of nymphomania. With her previous fitness level, I estimate she can be bred up to 27 times before succumbing to an exhaustive state and her body expiring." The doctor spoke notes into a recorder over her naked body moaning and groaning against the beast.

Kim couldn't take any more pleasure, the near continual orgasms were draining her energy and strength. She arched her back one last time off the stone table as she felt the creature push deeper than ever before and hold inside her. Cum flowed deep into her womb as she collapsed back down on the table. Her body went limp as the creature held firm inside her. She closed her eyes as a deep exhausted sleep washed over her.
