"Akari," 29, works part-time as a nude model. Today she is doing a figure-drawing job together with a male model. During the session, Akari becomes extremely excited when she sees the man's large member up close. Even after returning to the dressing room, she can't control her aroused body. Although the male model is on the other side of the partition, she can't hold back and quietly begins to masturbate — but masturbation alone isn't enough.
