Tall and glamorous Mio Kayama writhes with the intense high-leg pleasure that bites into her crotch! One day, Mio, a female teacher who works at a private school, injures her president's son and student who is also the ace of the swimming club. She is then summoned by the president and given a leotard to look after the swimming team until her son recovers from her injury. She can't refuse and changes into her tiny swimsuit, but she can't hide her private part and bites into her crotch intensely, and her body gradually comes out obscenely.
