Michelle's breasts and new penis were pinned uncomfortably to the ground when she fell. She cried out in pain, immediately rolling over to relieve the tension. For a while she just lies there, trying to recover from the orgasm she had. It was incredible, far more intense than anything else she'd ever experienced.
Sitting up, her penis drags against the ground. But beneath that, something soft presses against the floor as well. Michelle carefully lifts her cock out of the way so she can see that there's a bump protruding from her crotch where her pussy once was.
"That's not... it can't be..." she thought. But she knew it could be. Whoever the hell put her here just gave her a penis. Why couldn't they give her balls too? Prodding the lump with two fingers, Michelle was treated to waves of pleasure. It was just as sensitive as her pussy had been.
"Oh my god!" she screamed, as the lump started to swell with each touch. As her arousal grew, so did her new genitals. Her cock quickly became erect again, and the bump pushed further and further away from her body. A crevasse formed, and the one large lump broke into two.
Michelle was soon able to cup her growing balls in her hands. The feeling of her hands touching this new organ, and feeling as hair began to cover them, it was beyond anything she'd ever felt before. When her balls finished their descent, she came. Long ropes of cum were sent flying forward, and pattered onto the floor like rain drops hitting a roof.
Loud echoes as each splattered on the ground. Michelle's cock was like a geyser, she didn't think the cum would ever stop flowing. But slowly it did. Michelle fell back against the floor, completely spent. Her penis retreated, and her balls didn't feel as tense or constricted. When she was finally able to prop herself up on her elbows, she saw that after cumming, her body had grown.
"Holy shit." she said, inspecting her body. Her penis was soft, but it was at least ten inches long. And her balls looked like tennis balls. Complete with thick pubs, that covered her ballsack, the base of her cock, and her asshole. Pleasure was soon replaced by shock and horror. What was she turning into? A man? No, she still had her breasts, and the only place she'd grown hair was her crotch.
Her thoughts were interrupted by a low hiss. Michelle turned around to see the doors to her prison open.
