The H-game by Amalgame features subjects not typically included in college curricula, such as sex education. At our all-girls school, a male teacher takes it upon himself to educate students about carnal knowledge. He uses his authority to lure the hottest girls into his lair and has his way with them. In the end, these girls will learn some lessons they won't forget. Meanwhile, 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 finds himself endowed with a power the girls cannot resist.
