With her bright and energetic personality and beauty, Ms. Mina is popular not only among students but also with teachers. However, precisely because she is serious, she has succeeded in developing a peculiar study method. This method involves... having male students in puberty release the sperm accumulated in their testicles to focus on studying. Moreover, thoroughly emptying the inside of the testicles by making them ejaculate repeatedly is said to be most effective. Eager to confirm the effects immediately, Ms. Mina bounces her overly lewd big breasts and huge ass around as she enthusiastically milks students for semen!
