At first glance, Ms. Nanao seems serious, but in reality she's a naughty homeroom teacher who loves young men. She makes a home visit to the home of her student Takahashi, whom she has had her eye on for some time, and when she finds out that his parents are out, she doesn't want to miss the chance to be alone with him, so she goes into the house. In a one-on-one interview, she finds out about the sexual worries that are typical of adolescence, and then she forcefully engages in a French kiss. Their lips overlap, their mucous membranes intertwine, their tongues entangled... the long, passionate kiss leaves no time to breath, and passion wells up between the beautiful teacher and her student!
