"Fucking My Sister's Boyfriend"

I was hanging out at home when my sister´s boyfriend came by to pick her up. Unfortunately, neither of us knew when she was going to be home. I checked my phone to see if she sent me a text, but it turns out she won´t be home for a while. Now what he doesn´t know is that I´ve been crushing on him big time for a while now. I´ve been wanting that big cock all for myself ever since they got together. Next thing you know I shove his big cock in my mouth. Dreams do come true. But he asks the most important question “Your sister won´t be home anytime soon, right?” I confirm his question and proceed to fuck the shit out of him and his big cock. He leaves a load all over my face as a thank you for the good fucking.
