Yokoyama, a young bachelor, has recently become very curious about a strange rumor that has been whispered around town as if it were true. The rumor. A vulgar and low-key rumor, spread among the men of the neighborhood with vulgar smiles. It says that Mrs. Mochizuki, a beautiful housewife from the neighborhood, is a slut who will do anything with anyone if asked, who opens her legs immediately if asked, and who, despite her face, is extremely lewd, a woman known only to those in the know. While Yokoyama laughs, thinking that such a thing couldn't come from such a serious-looking housewife, ever since that day, he has been very curious about her, and today, as she walks around the neighborhood, her plump buttocks shaking, he finds himself panting and tailing her.
