During climax, her legs are always straight. (Arisu Mai's costume NEO-950)

The protagonist of this film is Mai Arisu, who surprisingly confessed that she learned to masturbate from her older brother when she was young. It's said that at the time she didn't even know it was called masturbation, and she would press her genitals against the corner of a table every day, enjoying the itchy sensation. This habit hasn't changed to this day; she reportedly still enjoys masturbating with the table corner every day. This is a special work dedicated to filming the beautiful 45-degree angle of masturbation with a table corner.
