.. they'd bartered her off like a common whore, and maybe she was one after all... !Knuckles moved behind her, as Wayne had moments before, and gazed ...down with eyes bulging wide in hot uncontrolled desire at the full white moons of her buttocks trembling in sacrificial offering to him. God, he had never seen anything like it! His balls tingled and ached, and he longed to thrust forward into the narrow teasing slit that was coyly being hidden from his rapacious view. "Get up on your knees again,. As he did this, he turned around, so for the second time that afternoon I got a look at his perfect bubble butt. I flet my cock getting rock hard and decided he wasn't going to tease me for much longer. I took my shirt of as I walked over to him, pressed my upper body against his back and put my hands around his round ass. God what an ass.He reached behind his back and found my cock. "Hm, somebody is ready for some action" he said as he turned around and looked me straight in my eyes. I could. Our mounds were slapping together. I could tell my balls were hitting my sister's ass. She was totally in fuck lust. Abby soon had her legs around my back. Her pussy muscles were gripping me hard. Maybe it was because I was fucking my own sister. I got more worked up than normal and I tried hard to control myself.After maybe a half hour had passed, I told Abby I couldn't hold it much longer and I was about to pull out.No Tom, stay inside me!" She cried out.There was no time to debate the. He smiled back and pushed it in my mouth. It was all the way in my mouth.I was enjoying it and so he was. He took it right out in few seconds and went down on me in 69 position. He knew this is now getting my favorite position. He took mine and eating and sucking right away. As he pushed his thick meat in my mouth. He started going in and out as he was fucking my mouth. He was moaning loudly. He continued and ejaculated in my mouth with a relief. Then he got up from me and positioned on my legs.
