I really love it when you do it hard and fast!”Cliff pounded his cock in and out of his sister. He pushed himself up, grinning while he watched her...full breasts wobble on her chest. After screwing her for about fifteen minutes, he flipped her over and pulled Tammy up on her knees.“Mmmm, I love it when you fuck me doggy style,” Tammy said.Glancing at the mirror, Cliff watched Tammy’s breasts swinging as they hung from her body. When he mentioned it, Tammy laughed.“It feels weird, but I like. There was nary a cloud in sight in the blue sky and the sun was just on the cusp of being unbearable, making its presence known but not too much that we would run inside cowering. The grills were out and Nick was manning them with a hawks eye of precision. If there was one thing Nick liked more than making my life hell, it was grilling. To his credit, the results were always spectacular. He always managed to come up with new recipes from the oddest ingredients and somehow the end product was. Then I went back upstairs and got in my shower when I heard hers go off. As I washed I heard a knock at the bathroom door and it cracked open."Can I come in?" Her little voice said as I saw her through the glass door.My smile said yes as I looked at her in her big towel and head wrap.She sat on the toilet across from me."Thanks for covering me up when you left. You were so sweet last night. I'm falling in love with you, you know. Don't stop what you're doing if that's what you want." She said. I originally thought this would all die down in a week or two but I was wrong. If anything the thought of watching Dave fuck Sarah had me going even more. It was a short time later and my fantasies began to evolve into something even greater. I thought about Dave fucking Sarah right before my eyes. I had cum even harder as I stroked on my 6 inch cock. Things started to get even more serious a month later. The thought of Dave actually fucking Sarah had grown way past just a fantasy. I now was.
