Based on the H-game by Amalgame. Certain subjects taught at college these days aren't always part of the official curriculum... Sex education is one such subject! At our all-girls school, a single male teacher takes it upon himself to provide the best education in carnal knowledge. By using (and abusing) his authority, he lures the hottest students into his lair and has his sleazy way with them! In the end, these girls will learn 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 a student, he soon finds himself endowed with a power that the girls cannot resist...
