The star of this episode is Mai Arisu, who made the surprising confession that her older brother taught her about masturbation when she was a *****. She says that she didn't know it was masturbation yet, but she would press her crotch against the corner of a table and enjoy the tingling sensation every day. She says that this habit hasn't changed even now, and she still enjoys corner masturbation. This is a special work focusing on corner masturbation at a beautiful 45-degree angle.
