Chastity Belt, Hot Wax, Whipping, Young StepSister Gives Strict Study Training to Older StepBrother, Who Fails His Exams Every Year

His older stepbrother fails the university entrance exam every year, so his younger stepsister helps him study so he can pass. She believes his sexual desire is bad for his studies and makes him wear a chastity belt and locks him away to prevent him from fapping. She makes him study while dripping candle wax onto his body to train him to concentrate on his studies no matter the situation, saying, “I’m dripping hot wax for you, big brother, so concentrate on your studies, hahaha.” She makes him solve practice questions, and when he gets them wrong, she hits him with a riding crop, saying, “If you don’t want to be whipped, then concentrate and don’t get the answers wrong, hahaha.” However, the hot wax is too hot for him to concentrate, so she enjoys whipping him every time he gets an answer wrong. She says, “I’ll help you with the chastity belt, hot wax, and whip until you pass your exams! Big brother, you’re really stupid, but I really enjoy helping you study, hahaha.”
