Monkeys Born for Reproduction

A male student who cleans school stairs with top student Numanaka peeps at her panties every day. Seemingly pure Numanaka actually knows, and one day spreads her legs wider with wet panties. After a noise exposes him and she flees, he follows her to the PE storage room, where she has stripped her lower half. They have oral sex, then bareback penetration and creampies as he says he wants to impregnate her. Classroom cutaways intercut continued intense sex and further ejaculations in the storage room. The male classmate and Numanaka reach climax in the final scene of their sexual relationship, with Numanaka smiling while feeling pleasure as the male classmate apologizes.
