[Following the VR version of Karamizakari, the series is being made into a live-action series!] The summer in which sex dominated everything depicted in the main story of Karamizakari has ended, and Niyama has returned to his daily life. The days of crazy sex are already a nostalgic memory. Even now, the desire to have sex remains... but at school, there is a fuss about a handsome new student. "Tomo-chan! Long time no see!" Niyama is suddenly called out by the handsome boy. The handsome boy, Sota, was a childhood friend who played naughty pranks on him when he was little. He is like a younger brother. It seems that Niyama is the one Sota had his first love. Meanwhile, all Niyama can think about is Sota's naughty appearance... He tries to shake off the overwhelming feeling of guilt, but sometimes he fantasizes about it. Then another boy, Mikami, appears. He is a boy he liked in middle school and now attends the same cram school... He goes to karaoke with the one he used to like, who always talks about sex. The sexual desires that he had been suppressing inside him begin to overflow, and he is filled with sex again every day... He feels like he is being consumed, but he is entangled in sex... Time does not stop... His youth passes by mercilessly... He falls into depravity as he is swept away, and just when he can no longer stop it with his own will, his childhood friend, Sota, who has a pure Kokoro, appears.
