Senior's mother Shiori Ihara
Tatsuya left his parents' home to go to higher education, but returns to his hometown for the first time in a while to visit the graves of his parents who died in an accident. Tatsuya's senior colleague, Yusuke, invites him to stay at his house, but Tatsuya, who harbors a faint admiration for Yusuke's mother, Shiori, spends a sleepless night and distracts himself by masturbating. However, Shiori sees him... Shiori was tipsy, and instead of being embarrassed, she begged for him to continue. Eventually, Shiori's hand reached out to her crotch and she said, ``Let me help you.''
