Hi, thanks for the reply. I don't know the name of the game, but I remember it has a similar story, the graphics are too similar. The boy lives with his busty mother and his goth sister, something I remember from the game is that you accumulate hearts with the mother, depending on the action you take. I remember some scenes in which the mother plays with the boy's penis while they are having dinner and the sister is there, it's very similar to demon deals, that's why I thought it was the work of the same author.
