The hentai I am trying to find is a solo male and female, and the main guy got kicked out of his mother's place. The women, whose older then him, takes him in and at first nothing happens. Then they end up doing the dead, but after the girl teaches him how to make food (I don't remember if they did the dead before or after the food.). Skip forward and he finds her in the same place but he has a cut on his head because he tried making it for his mother but she got angry, and said something along the lines of, do you think I'm a bad mother. Then I believe they do it again.
Thanks so much
