Was it because of their huge breasts that they couldn't go to college? Or was it because they suppressed their overly strong sexual desires? They'll definitely pass next year! The stress of pushing themselves and the daily grind of studying has driven these big-breasted students crazy. Since the only man they have apart from their fathers is their cram school teacher, they secretly seduce him, and show off their slutty side by using their bodies to find out the surefire way to pass the exam. They don't care about the exam anymore! Teacher, please teach me lots of things that feel good. The five students who are repeating the entrance exams shake their big breasts and beg for raw insertion.
