So the doujin is about a father that remaries to a hot milf. He has a white haired son. After the father and the new step mom have sex she is unfulfilled. The step mom goes to watch soemthing only wearing a towel. She hears something from the son's room so she goes to check and catches him watching porn. The son is very nonchalant and the mom sits to watch with him. She also gets naked. Then the go on the son's ved to talk about stuff including girls and the stepmom kisses him. Then they fuck. It has a very simple art style and i think it's western
