A man who is outed as a virgin in class and mocked by the girl he admires. Desperate to have sex, he begs his childhood friend Natsumi, known for her promiscuity, to help him lose his virginity. Initially reluctant, she eventually agrees if he has a condom. He uses an expired condom, which breaks during his clumsy thrusting, leading to unprotected sex. Overwhelmed by the sensation of raw sex, his pace quickens drastically. Even Natsumi, who was initially unresponsive, starts orgasming repeatedly and accepts multiple internal ejaculations.
