Mina, who decided to appear in an adult video to lose her virginity, brought along a real "virginity certificate" issued by a certain hospital in Tokyo and tried to film it. The filming progressed smoothly as a work of loss. Finally, the sex scene was recorded, and for some reason the actor only caressed her anus. He held her, made her get on all fours, and tricked her into inserting his penis into her anus!
