"Actually," Derrick said with a blush. "I....I'd like to try becoming a girl this age, maybe a year younger?"
Hebe grinned from ear to ear. "Oh? Why? Do you not enjoy being a male...." She ran her hands along his enlargened penis, eliciting a shiver through his younger body.
Derrick stuttered. "I d....do. I just...I always wondered what it would be like to be a girl, grow up as a girl instead of a boy."
Hebe nodded. "I see...well my friend circe prefers girls to boys to tell the truth. I am sure she could find some fun things for you once your changed. Let's see here..."
The woman began to rub her hands along his body, and Derrick braced for what was about to happen. He watched as mud slid along his skin which became smoother, his body smaller, more lythe, even moreso than he already was. He was distinctly younger, but there was something very different now. Hebe began to wash her hands through his hair, sending coarse mud away, and as it did, he felt his bangs and his hair extend down to his neck. Hebe ran her fingers over his face...and he felt a little shift in it. Looking at his reflection, he sort of recognized himself, but his face was just a little bit different, with longer hair, he almost looked like a boy with just long hair.
That didnt last as those dexterous fingers slid along his member...and as they did, it began to retract into his body. The sensation was extraordinary, and Derrick tried his best to watch what was happening but his eyes rolled back into his head. He felt something push inside him, his groin seeming to open up from within as his testicles pulled up into his body and changed their makeup.
Then...suddenly it was over. Derrick sat there, awash in the sensations....and looked down. He was no longer a he at all though. Derrick....was now a girl.
Hebe smiled. "Welcome to girlhood, Danica."
