He is my little sister's boyfriend!!! I thought he was a very dear and loyal one... And then something like this? Without warning, he just uses me in the bathroom. Just because he knows that I occasionally get it on with my dad's friend and my uncle, he thinks he can take advantage of me like that? He fucks me ice-cold on the sink and sticks his extremely hard cock in my mouth. Then he squirts cum in my cunt! It stays in the family...
