....... It would be a waste of a perfectly wonderful evening between two adults if we just said good night and got into seperate beds."By now, I knew ...hat it was on. I was about to step into a relm of taboo that few men have dared to venture. "Well," I said to her, "I cannot think of any woman I would rather be with tonight than you." With that she landed a huge wet sloppy kiss all over my lips, as if someone had opened the gate at a horse race, and she rushed right into action. She was kissing. As I stood there watching my little sister do her level best to seduce me to do her will, a thought... a wicked, immoral thought, began forming in the animal part of my brain. What if...I knew it was wrong. I mean we live right in the middle of the Bible Belt and this was incest! Still, she was right–it had been a long time since I had a warm body next to mine and Valerie was... well she was pretty damn fine to be truthful! Sure, she was a little younger than I liked, and she didn't have much. "I know." Pete replied, right before his balls unloaded yet another full load of semen inside of her. "But as long as your sister is remaining difficult, I wouldn't be at all disappointed to continue to get to know you a little better."They kissed for awhile while Pete's cum slowly finished its last dribblings inside of her and he caressed her nearly bare ass, his finger probing and questing for her tight little asshole. She giggled, but pushed his hand gently away."Sorry lover, I have to have. Laying across her smooth tanned legs made me begin to get hard. She started the spanking gently and worked up in speed until she was hitting fairly hard the slapper stung some but it made more noise than pain. She stopped every few swats to rub the edge of the pattle up and down my crack. By the end I was fully erect and ready for what I hoped was next. Look at that juice you left on my legs she said as she scooped it up and licked her fingers we need to do something about that. Taking me to.
