START-419 The nagging teacher who dodged his wedding date is a pervert who enjoys exposing himself in class. Students discover his hobby and are forced to mate like monkeys, awakening their feminine instincts. Mahiro Yui

The teacher Uii, who always wears sweatsuits and naggingly guides the dumb male students, has a tomboyish personality. The students laugh about her behind her back, saying 'She definitely doesn't have a boyfriend,' 'She's probably still a virgin,' 'She's completely missed her marriageable age.' However, her true nature was an unusually strong sex drive. She would take advantage of class time or after school when no one was around to expose herself or masturbate in the school, reveling in her pleasure, she was a complete pervert.
