Good morning, afternoon, or evening. One of these days I remembered the time I played an interactive story game

I don't remember its name, but I do remember that it was about a fantasy world. I don't remember many details beyond the fact that the protagonist is a futanari, half human, half demon(?. Her mother is a human witch and her father (who does not appear in the game, I think) is a demon, I think she also had a sister though I don't really remember, she also has a girlfriend who is human

The game features lots of cumflation, you can go to certain areas, either where's your girlfriend, your mother, your sister, or to a forest with some monsters (I remember there's an harpy) to fuck them and fill them with cum

I apologize if the details I gave are somewhat scarce; I don't remember much since I played it more than 3 years ago. Even so, if anyone knows the name of the game or at least knows something, please let me know
