Chiharu, who appears to be a serious married woman, is actually a lecherous pervert. She sets her sights on a boy who sent her a love letter in middle school and teasingly reveals her panties without protection. He grips his erect penis while she gazes at him with lustful, glistening eyes. She peeks at classmates who start having sex in the toilet, becoming even more aroused, and begins right there in the hallway before returning to the banquet hall. After sucking on his penis and being penetrated from behind, she lets out a moan. To avoid being caught, they move to an empty room where Chiharu thoroughly enjoys sex with her former classmate.
