Certain subjects being taught at college aren't necessarily on the curriculum. Sex education is one of them. At an all-girls school, one male teacher takes it upon himself to educate his students in the ways of carnal knowledge. Using (and abusing) his authority, he lures his hottest students into his lair and has his sleazy way with them. By the end, these girls will learn some lessons they'll never forget.
At another college, a glowing, phallus-shaped artifact possesses magical powers that turn innocent girls into raging sex maniacs. When a teacher is seduced by one of the students, he becomes possessed and soon finds himself with powers that his female students can't resist.
