i know western NTR isn't really talked about here, but i just played a very promising NTR game. so far version 0.1 doesn't have any NTR, but the foundation is already set.

your brother lied about taking dirty pictures of your mom. it was really him and you got blamed. you had to live away from your family for a few years so you could "get over your thing you have".
you come back and they of course aren't generally comfortable around you at the start.
so that's the premise. you now how to win the girls over or your brother will. you are in a competition with your brother to get into your families pants lol.
oh and for being the first version, it has a lot of material with the mom already including getting into her pants already.
developer said the brother will start making his moves next update.
