A son falls in love with his mother, Yu, because he thinks too much of her. His twisted desire to make her his own woman overflows and he starts to run wild. "From today, I'll be in charge of your sexual desires, mom." Following his instincts, the son attacks Yu, forcing her into a chastity belt and trying to control her body. Although Yu is confused by his son's actions, he resists desperately, but gradually he can no longer suppress the throbbing in his body.
