Multiple penetration isn't necessarily mmf. She can have a dildo up her ass when he fucks her, or have a ffm threesome where the second girl has a strapon and still counts as multiple penetration, since you know, multiple "things" are penetrating her. There can be only women present and still have a multiple penetration scene. For the sharing thing, I disagree. Since it's clearly and incest game, they have a relationship. If they're not in a relationship wtf does the "romance" tag doing up there, since there isn't any other "couple" in the game, except for the parents of course?
