As her third cum was reaching its peak, I slid my finger up into her hot snatch. She fucking exploded! I was pumping my finger in and out of her pussy...and as she came I sucked her clit into my mouth and flicked my tongue rapidly across it. As she was cumming again, I recalled watching a funny comedian named Sam Kinneson on a video tape that Mike's dad has. On it Sam says if you want to eat pussy like a pro and have her remember you, lick the alphabet.I got as far as "J" when she orgasmed hard. However, I knew that I would have to find something to do or I would go nuts.My wife, Theresa, was absolutely no help. About ten years ago she became involved with a Fundamentalist Christian Church and that became her life. She breathed, ate and slept that church. About four years ago she advised our two grown children and me that she was dedicating her life to god and everything else came after god. She also told me that in dedicating her life to god she would forego all sexual activity. So. I finally gave up, my throwing was terrible, and decided to chase him, instead. I jump onto his back, he tripped, and we wrestled on the ground, quickly getting covered in snow. I can tell he is being gentle with me (thank you, thank you), and I get away, but he soon has me trapped at the dock. My only escape is to go down the dock, which is no escape at all. I plead for truce and he reluctantly agreed. I walked toward him and he was visibly tense. Clearly, he is expecting me to break the truce. As he was sucking and kissing on her clit, I put my hand into my shorts and had began to stroke my cock. I was so turned on seeing my dad and little sister go at it, with dad occasionally breaking stride to kiss her lips and stroke her hair. My mind was filled with questions as I still held my shaft in my left hand. Was this their first time? Does mom or anyone else know what they have done/ are doing? Was this bout of sexual lust the first my teenaged sister had experienced. As.
