"Senpai, make me cum... Please...!" Ayakawa Yuki has entered a university in a very rural area where there is little entertainment. Yuki's only way to relieve stress is through extreme delusional masturbation. Inspired by the liberating feeling of the countryside, she finally went beyond her fantasies and actually began masturbating in public. However, late one night, Yuki was approached by someone during one of her masturbation sessions! She managed to escape from the situation, but may have been seen... The next day, she attended a drinking party to welcome new students, but soon she found the party turning into an orgy...! Feeling awkward, she decides to run out of the bar, but a man named Kirishima Ryosuke, a senior student, follows after her. "What were you doing last night?" The secret is out, and it was one of her upperclassmen?!
