The sadistic female tutor makes her student into a pony boy, rides on his back, and makes him study while hitting him on the buttocks with a spanking whip. The tutor puts a collar and leash on the student and makes him study, occasionally pulling on the leash to make him lick her pussy and anus, and then makes him study again. The tutor makes the student study while giving him a handjob. When the student is about to cum, the tutor tells him, "If you ejaculate, you will spit out what you've learned along with your semen, so I won't let you ejaculate," and puts the chastity belt on him again. The tutor then makes the student lie on the floor and Facesits him. The tutor then makes the student lick her pussy until she cums. The tutor is excited by the fact that the student can't ejaculate because of the chastity belt, but she is the only one who can cum and feels superior.
