I, the head of the women's swimming club and the men's head of the swimming club, have sex friends. She spends all her time in the clubroom having sex every day without practicing. But we've gotten a little bored... One day, at the suggestion of my saffle, I decided to call a new member who is eager to practice, serious, and looks cute. A new member who is suddenly called by the manager of the men's and women's clubs. "It'll be a problem if an excellent girl like you quits, so why don't we do something fun like this sometimes?" In no time, I was captivated by the female manager's rich lesbian technique and my erection!
