A man who is outed as a virgin in class and mocked by the girl he admires. Desperate to lose his virginity, he begs his childhood friend Rika to let him have sex with her. Initially taken aback, Rika eventually gives in, saying 'Okay, if you have a condom.' He uses an expired condom for his first time, but due to his clumsy thrusting, the degraded rubber breaks, leading to unprotected sex. Overwhelmed by the sensation of real vaginal intercourse, he speeds up his thrusts. Even Rika, who was initially unresponsive, starts orgasming repeatedly and accepts multiple internal ejaculations.
