A talkative teacher who missed her wedding date is a super pervert who enjoys exhibitionism in class and on campus. Her students discover her interests and she's forced to mate with them like a monkey, triggering her female instincts. (Yui Mahiro START-419)

Ms. Yui, always dressed in sportswear, nags her male students who aren't very bright. Behind her back, students mock her, saying things like, "She definitely doesn't have a boyfriend," "She's probably still a virgin," and "She's completely missed her marriage window." But her true nature is that she has a much stronger sex drive than others, and she's a super pervert who always targets exhibitionism and masturbation on campus during class or when no one's around, indulging in pleasure.
