Sumire is a transfer student from a village where it's customary not to wear clothes. She has no sense of shame or erotic feelings yet, so even in front of the male students, she shakes her boobs, spreads her legs wide to reveal her bushy pubic hair, and when she picks something up, she shows off her plump ass, revealing her anus, unconsciously seducing them! With her wandering around like that, the boys can't stop getting erections!! Huh? Are the boys excited by seeing me naked?? If a naked girl transfers to a school—the teachers and the boys in the class will all get involved, and the school will be filled with sex and cumming all over the place!!!
