Seitenkan (The Sex Change) ~You can cum inside me!?~

Akira lived from day to day without any change. Every day he protected his little sister from their alcoholic father. School was a drag. It was a boys-only prep school. "I hate this life!" he thought. One traffic accident later, and he awoke as a female. (!?)

There was no way "she" could protect her sister like this... unless she played to her old man's perverted nature. "Well hello cutie, you want to take her place?" Akira's father offered predictably. To spare her cute imouto, Akira spread her new feminine legs. In spirit still a boy... and with his own father... it was like a nightmare. But physically, another feeling took over...

Teacher and student, father and son/daugther sexual experiences. Akira lives day to day with huge change.
