Suddenly Amy bent over and looked to in pain. Surprised and frightened that her hormone might have caused the sudden reaction, Kiera quickly made her way to the still bent over Amy who seemed to be panting rather wildly. Out of nowhere, Kiera found herself flying through and crashing into the back wall before a the now slightly muscular arm of Amy kept her in place.
"Amy-gasp- what are you-doing?"
Instead of answering though, Amy shoved her tounge down Kiera's throat and started to make out roughly with the pinned scientist. Unseen and unoticed by either women, Amy's clothes started to stretch as her form started to gain large amounts of muscle mass. When the changes had finally finished, Amy was now completely naked as she looked like a professional body builder. The changes didn't stop there though. Due to her new muscular physique, Amy's body started to produce it's own hormones to counteract the synthetic sample. First she grew from her original height until she was over a foot taller than Kiera but still managed to kiss without trouble. This increase in height also made her once blocky body look more manageable and slimmer to look at. Next were her brea st which exploded in growth until each orb of flesh was bigger than Kiera's head.
With her rush of hormones now over, Amy slowly gained a semblance of control and pulled her tounge from the now unfulfilled girls mouth. Seeing such a look of want and desire on her friend's face, Amy couldn't control herself before ripping of Kiera's clothes right then and there leaving them both stark naked. Before she could dig in though, Amy noticed something strange occuring.
