I'm looking for a game I played some months ago, the mc had 3 sisters, 1 younger redheaded that I think had yellow eyes and is very close to him, 1 older with black hair that is kinda indifferent and the youngest who is short and really hates him and practices martial arts. I can't really remember the mom. I remember that there was a crazy scientist who was being cucked by her husband with their maiden, the husband was black and I think the maiden had white hair. So the scientist makes a kind of virus that makes people crazy horny, and she later offers it to trump, kim jong un and some other people (lol). I remember that at the end of the version I played you could choose to fuck the maiden (the one from the cucked scientist, that has moved to the house next to yours and is now your maiden) and she could be either futa or female. Thanks in advance
