Rena, an adult photography-club student role-player, is taking pictures in a park when an older man approaches and kindly offers her advice. She grows fond of him, then later visits his home to see his work and ends up posing for erotic photos. When she confronts him about her unease, he intimidates her by reminding her of everything he has taught her, fondles her, forces her to give him a blowjob, and ultimately gives her a hands-on lesson in sex.
