A boyish female school student who had developed an immature body and was able to become a female

"How can you become a woman like a teacher?" I'm a fool of a boy and a woman... (first half) the invitation of lesbian with the notion of becoming feminine! The immature body responds to the sluggish tongue use of the female teacher! Moreover, the gym teacher was mixed, and the woman and the man were blamed, and the girl knew the pleasure of onna! (the latter half) "I want to become a woman." The teacher made it to the oneness of "it was done" and was able to be done by many times many times.
