Makoto, who moved to Tokyo due to a job transfer, was attracted to the ripe sex appeal of her neighbor's married woman, Eriko. One night, he listens to the seductive voices coming from next door, follows the wall, and discovers a mysterious hole. When you kill your voice and look into the hole, you can see Eriko's obscene figure. From that day on, Makoto becomes obsessed with peepholes, and not only peeps, but also puts cocks in the holes to satisfy her desires. Then it feels like he is really having sex with Eriko.
