I'm visiting my sister and her husband for the evening. When I enter the living room I only see her husband sitting there watching a movie. I asked him where my sister is and he said that she went to get pizza because we are having a movie night. Then I took this opportunity to take advantage of him. I've always had a crush on him and a lot of woman talked about how big his cock is and I wanted to see it for myself. Eventually he caved and I started to suck his cock. Going down balls deep and keeping it there for a while with his cock down my throat. I grab both balls in one hand and continue to suck him off. We have to be fast because my sister can be back at any time. Eventually he came in my mouth and I start to play with it in my mouth, let it drool onto my hand and slurp it up again. When I was done playing with his cum I had to swallow it so that there is no evidence of this event ;)
