the smell of your sister's sweat, otowa leiko.

A husband and wife who left their hometown in Tokyo. His younger brother-in-law, Atsusuke, who lived a womanless life after being chased by his father Shigeo's care, was fascinated by Reiko's sexuality. Kosuke smells the smell of Reiko's underwear, which was placed in a disguise basket. The female odor released from the mature woman's body breaks her reason and awakens reproductive instinct. The stinky smell of the sister-in-law and brother-in-law interacting with each other's sweat and body fluid is soaked deep in the tatami mat.
