A NAGGING HIGH SCHOOL TEACHER WHO MISSED HER CHANCE TO GET MARRIED IS A TOTAL PERVERT WHOSE HOBBY IS EXPOSING HERSELF IN SCHOOL DURING CLASS.
When her students discover her hobby and force her to mate like monkeys, she is reminded of her female instincts.

Tadashi Yui is a tomboyish teacher who always wears tracksuits and nags at her dumb male students. Her students laugh at her behind her back, saying things like, She definitely doesn't have a boyfriend, She's probably a virgin, and She's completely missed her chance to get married. However, her true nature is that of a total pervert with a stronger sex drive than most, who enjoys exposing herself and masturbating on campus during class or after school when no one is around.
