During his middle school years, a son named Tadashi witnessed his parents having sex. During puberty, seeing a woman's naked body for the first time... he began to see his mother as a woman. Since then, the son who secretly peeped into his parents' bedroom bought a video camera and filmed their acts, finding the highest pleasure in masturbating to these recordings. He wanted to touch his mother… he wanted to enter her… His mother's maternal instincts began to accept him, and they both started to indulge in pleasure.
