You nearly trip trying to pull off your clothes while running to the bathroom. The room is already filling up with steam as you join Gina in the shower stall. She is short, you realize, not more than 5' 2", and very slender. As your hands explore her narrow hips and small breasts, you hear her whisper in your ear, "You know, I only have one place left that hasn't been violated today." Wrapping her fingers around your shaft, Gina guides your tip towards her ass. You find her behavior strange, though you have no clue what goes through the mind of a woman who has been raped by an inanimate object, and with that thought in mind, you feel her hands grip your hips and force yourself into her.
Gina shrieks as you penetrate her, though you don't know if it is in pleasure or pain. Her ass is so tight that it almost hurts you, but rather than pull away she draws you further inside her, inch by inch. You barely get your entire length inside her before Gina's screams of passion and her overwhelming tightness drive you past the brink. Your balls clench as they force your seed into her, and with a warbling cry, Gina cums as well. The two of you stand there, your arms wrapped around Gina's body, both of you feeling the little aftershocks of your orgasms. You wait for your erection to subside, so you can pull out without hurting Gina, but it doesn't seem to be happening. If anything, it feels like she is getting tighter. Gina squeals as you cum inside her again.
You hear Gina gasp, "It hurts, but it feels so good. What's happening to me..." Her hips begin to swell under your hands, and her waist narrows slightly, transforming her petite figure into a sexy hourglass. You slide your hands up her body and begin squeezing her breasts as they press out from her chest. With a satisfied moan, Gina moves her hands next to yours, both of you rubbing her flesh as her breasts expand from small A-cups to healthy C's. You finally find yourself able to pull away from Gina's body, but as you do so you notice that you have changed as well. You cock has swollen to twice its original size, and its shape has changed slightly as well. Below them hang a swollen pair of testicles, much larger than your own. You reach down and touch yourself, half afraid that you will feel something rubbery, but to your relief you do not. You realize that your genitals are now a flesh and blood copy of the Devil's Dong dildo.
