A man whose virginity is revealed in class and is made fun of by the girl he admires. A man who really wants to lose his virginity begs his childhood friend Rika to kneel on the ground and let her have sex with him. Rika was taken aback at first, but gave in and said ``as long as there's a condom''. She takes out an old condom and has sex for the first time, but the deteriorated rubber breaks due to the clumsy piston and she has sex raw, experiencing the feeling of a raw pussy for the first time.
