Well, I even like the guy but the truth is that when my sister and her boyfriend get upset with each other, I'm the one who gets a reward. My sister has a very difficult temper and she's a spoiled brat so when she gets really pissed off with her boyfriend, she wants her revenge but at the same time doesn't want to loose the guy because she really likes him so to play it safe and get herself calm, she asks me to give her a good revenge sex. She says no one will know and she feels a lot better after and she's ready to forgive him. Yes, that's the way my sister's head works. Don't try to understand.
