Wakaya, an idol otaku, felt disgust at his young and beautiful mother being looked at with sexual intent by his friends. However, one day, he witnessed his friend Masao unable to hold back any longer, groping his mother's large breasts and forcing her to perform fellatio. Since then, Wakaya started to see his mother as a woman and became more interested in the bodies of women around him than untouchable idols. "I want to take a bath with you again," he invited his mother, and during their first bath together in years, he was captivated by her young and beautiful body, ultimately having his first sexual experience.
