I came out of the countryside to visit my father and decided to visit my younger brother and his wife's house. Kyoko, my brother's daughter-in-law, has a wonderful smile and an erotic body. Even though I know it's a bad thing, I fantasize about the lascivious appearance of my brother's wife. Kyoko masturbates to show off, Kyoko gives a in the bath, and my delusion grows more and more.
