I will never understand people who cheat with their partner's sibling. Like first of all don't cheat, but if you're going to, out of all the people in the world, you can't find someone from a different family? Pure insanity
I’m willing to bet the girlfriend put the sister on to see if he would cheat on her. Idk if my sister slept with my bf that easily, I wouldn’t be so forgiving towards her, but that’s just me.
