Mai Arisu, who made the surprising confession that her older brother taught her how to masturbate as a child, is the star of this video. She says that even before she knew what masturbation was, she used to press her crotch against the corner of a table every day, enjoying a tingling, pleasant sensation. That habit hasn't changed to this day, and she still enjoys corner masturbation. This is a specialized work focusing on beautiful 45-degree angle corner masturbation.
