My mother got mad at her daughter's sex... ~I couldn't hold it in and ended up having sex with the son next door!~

On the way home from shopping, Yumi invites her to tea to thank Kazuya, her neighbor, for bringing her luggage. However, as I entered the house, I heard a gasp... Her daughter, Misa, was having sex with her boyfriend. Yumi, whose crotch aches at the sight of her daughter, has become a woman, can't stand it, and can't hold it in and begs Kazuya to kiss her... Furthermore, she thrusts Kazuya's tightly bulging cock into her wet pussy, and devours pleasure. From then on, Yumi, who can no longer be stopped, becomes addicted to an affair with Kazuya whenever she has time...
