Since her husband became impotent two years ago, Chiaki has been living a sexless life in frustration. One day, she caught her son Keita masturbating in his room and couldn't hold back any longer. She approached Keita and said, "Masturbation can't satisfy you, right? Why don't you have sex with your mom?" Amazingly, she tried to seduce her own son. Unable to resist the intensity of his mother's changed demeanor in front of a young penis, Keita made a mistake. However, Keita was also quite the "stud," and he wasn't about to stop there... The mother and son, unable to contain their escalating desires, continued to copulate relentlessly from dawn till dusk!!
