A wife is frustrated that her shut-in husband spends every holiday locked in his room playing games and browsing the internet. Because constant masturbation has killed their sex life, she asks her mother Chisato for help. Confidently entering his room, Chisato jiggles her outrageously voluptuous body while closing in on the man who refuses to look away from his monitor. Her escalating sensual assault finally tears his eyes from the screen and fixes them entirely on his mother-in-law.
