Once in a Lifetime 3D Step Sister Game Sex

In the game you are from normal town where you live an apparently normal life with your family, you have a very annoying step sister, but you need to study hard if you want to get through finals but it won’t be an easy road, since you horny step sister keeps showing up at your room every night asking for sex, you’ll soon discover that here nothing is what it seems and things can heat up very fast.

while you play this game you character gets in complete control by the sister at first when she shows up, you know women always have control over men sexually, than she asks you if you wanted a blowjob for free, and of course you accepted her offer, having sex with your step sister Rebecca will be on every mission you complete in this game, since things gets harder with every level you advance to, and without her help there is no way you could complete them.
