Yes it can even lead to death if 1 chose is wrong but if you make sure that her mom has 3 points and her sister has 1 point you should be save for the rest of the game, not sure how many points it needs to break the gf route. If you got 4 points for her mom and 0 for her sister game over kiss of the death.If you got i thing 6 or 7 points for her mom the gf route breaks at the futa img, need to test that more.
Andrealphus what are nice game cant wait to see more if this nice game keep it going, one question or maybe two why the kiss of the death from her sister and is ther prego planned

I love the gf route and the dom route of curse for me no ntr on both routes, ntr is not my kind of kink.
I thing he means the switch from the sub route to the dom route.
