I poured the cum out of her panties and into her mouth. She began to drink and didn't stop until she had consumed every last drop of my warm cum. I ...rabbed my camera and snapped several pictures of Jessica drinking my cum. "Now that... that was fucking amazing!" Jessica yelled. She jumped on top of me and made out with me on my couch. "Mhm, I love your lips," I said, as soon as our lips had separated. As I said those words, I placed my right hand on her pussy and stroked it. "But I love. ... She stuttered a little and said, "I think I know who you are..."My mind was racing! I thought, "Who the fuck is this chick and why does she know who I am?"So I asked her, "How do you know me? Did you google me?"She laughed and enquired about my sister. Now shit was gettin weird.She was then certain she knew who I was. But refused to tell me how she knew me.So I dismissed it and told her we should go dance. And just then she told me.Turns out she was the mother of one of my sisters best. His face showed some evidence of acne scars and his teeth were large and widely spaced, which to Sarahs mind gave him a decidedly rural look. He was definitely not a man she would have been attracted to under normal circumstances. But in this situation, the elements of risk and adventure combined to push her toward initiating sex with him. Anyone who knew Sarah would never in a million years believe that she was about to have sex with a complete stranger, and a black man at that! But then. All I could think about the last two days was sticking my dick in my sister and the more I thought about it, the more erotic it seemed. I was always sort of awkward around girls and had never had a real girlfriend. The closest thing I ever had to a romantic kiss was some experimenting with the 8 year old girl next door when I was 10, but then she moved away. So my half-sister seemed to me like the only real girl in the world. I wacked off about six or seven times over the weekend just.
