When female tutor comes to student's house after a week, she unlocks student's chastity belt and says, "You held back from fapping your small, uncircumcised dick, good boy, hehehe." She tells student, "Study without giving in to your sexual desires," and teases him by showing him her panties and pussy, rubbing her tits against his head. When student gets a question wrong, she spanks him on the buttocks with a spanking racket, lifts his nose with a nose hook, hits his dick with a ruler, and does face sitting. When student gets the question right, she rubs her tits or butt against his face or gives him a hand job as a reward. When student finally solves all the questions, she gives him time to jerk off as a reward, and watches him jerk off. Student is happy to jerk off for the first time in a week, but just before he is about to cum, she puts a chastity belt on him, locks him, and leaves, saying, "I said to OK jerk off, but I didn't say OK to cum. See you next week, bye, hahaha."
