Hibiki, a returnee with soft, massive breasts, transferred into an all-male class! And she's always naked, so the horny guys are all captivated by her. The teacher who was supposed to be lecturing ended up having sex, students in class took turns getting blowjobs, she was assaulted one-sidedly in the men's restroom, and in the changing room, there was forced three-way action with lotion. School life filled with free, unrestrained sex with a naked schoolgirl is incredibly stimulating!
