GVG-437 _Asked to sleep with dad, took off mom's underwear in the middle of the night

Shota's father had a woman outside, so his parents often argued and decided to divorce. Without my mother, my father often bought curry from the store because no one knew how to cook rice. Not long after, his father said he would bring his new mother home. Shota was very happy, so his father also felt reassured. Shota's stepmother is a young, beautiful woman with a much bigger butt than his mother's. He quickly falls in love with Yui and especially her butt. Shota continuously acts both sexually and innocently, making Yui both angry and amused. But Shota becomes more and more daring when he dares to make love to her right next to her husband! She was very angry but when she discovered Shota's feelings for her, she changed and wanted to give him all her heart.
