My stepmother has decided to live with me after my father remarried. She is drinking a lot and is at the mercy of the sex appeal of adults, and her family is in a complicated mood, and their skin is touching as they share a kotatsu. To call her mother, I get lustful and erect because of her sexy body! The other person feels the same way, so they secretly flirt inside the kotatsu. Eventually, the two of them can't control themselves and find themselves in a situation where their father is nearby...
