Castigo y castidad con cinturón, lecciones de seducción por una tutora sádica

The female tutor tells the man, "Because you always masturbate, you spit out everything you've learned in class along with your semen and forget it! From now on, I'll train you to study without giving in to temptation, hehehe." While the man studies, the tutor shows off her tits, thighs and panties to the man, puts her tits on his head, rubs them against his body, strokes his dick with her hand, and teases him with a grin. When the man gives in to the tutor's temptation and gets a question wrong on the test, the tutor punishes him by hitting him on the head, pinching his cheeks, slapping him, and crushing his face with the sole of her foot, laughing as she punishes him. The tutor pulls down the man's underwear, takes a good look at his dick, and says to the man, "Are you short? And it's uncircumcised, too, hahaha." She then tells the man, "I'll put a chastity belt on you so you don't masturbate, and I'll keep the key to the chastity belt. Well, study hard, hahaha," and goes home.
