Tl;dr: Looking for couple of twins/friends taking advantage of a completely submissive woman.
For people who doesn't play gachas, there's this game called ZZZ which a new character was introduced, and this new character is a die hard fan of the main characters (which are a couple of twins), to the point that she would worship them.
By the end of the patch, she moved to their home and some porn fan art about her being completely submissive to both of them startded appearing and tbh I find that idea hot as fuck.
Looking for anything similar where twins/friends take advantage of a completely submissive woman.
