Aya is too sensitive and cums easily. Her husband and wife's activities reach their limit and stop having sex once Aya cums. Her husband is not satisfied with their married life, and in the meantime, he bumps into her former part-time job and ends up having drinks with him. However, Tachibana is also a man. Because he was drunk, he felt aroused by the defenseless eroticism of a drunken Aya, and even though he thought it was bad for Tomoki, he committed a crime. However, despite being raped, Aya develops this feeling that she cannot describe.
