Blue Skirt: Dangerous Breeding(1984)

A teacher sets out to instruct a young high school girl in what should be an ordinary lesson. Yet when this gal turns out to be an outrageously vivacious, modern-day bombshell, even the simplest classroom routine spirals into a wildly scandalous and forbidden affair. This brazen young student, who deceives her parents and nonchalantly crashes at his home, exudes an almost deliberately provocative and irresistible charm. Although the teacher is a married man, his attempts at reprimand falter under her irresistible sexual features. Could it be that this fiercely free-spirited high schooler—living purely for the thrill of fun ends up transforming her mentor, taking him on an unexpected, sizzling journey into uncharted realms of temptation and forbidden desire?
