Adam's transformation - Futanari!

Adam's eyes were wide open and he looked down at his transformed body. All female, except for his tiny dicklet, that continued to pulse and ache.
When he exclaimed in shock and whimpered, his voice had changed as well to a clearly female higher pitch: "No.. no... what is happening? I just wanted a bigger cock..."

But right at that moment, Adam's body was rocked by yet another climax. A continuous torrent of cum erupted from his tiny dick, that suddenly wasn't so small anymore. It indeed grew! First slowly, then more quickly, as more and more cum blasted out of his growing penis.

Soon the spectacle was over, and Sarah marveled at the sight in front of her. Her brother, fully transformed, into a curvy, sexual and sensual futanari, with a huge girl cock like herself.

Sarah's own huge futa fuckstick was throbbing and stood to full attention at the sight before her, and she stroked it and stepped closer.

"It looks like you finally got your wish, Adam"
