“I feel a bit guilty but it sure felt great. Get your ass over here stud.” I joined her on the sofa and she gave me a long passionate kiss. I a...ked, “So when do I get my special present?”“Damn I almost forgot. How about if I start by sucking your big cock and then you can fuck my ass in the pool like you mentioned yesterday.”“That will do nicely,” I said. She made her way down, positioned herself between my legs and sucked my half hard cock into her mouth and I was instantly hard. She. Since they have rules that there’s no sexual contact between parents and their own children and vise versa, Chris had to fuck his wife Elizabeth, then Victor fucks his wife Kara. Then Paul fucks his girlfriend Gina. And David had to fuck Leah.They spread a cushioned mat by the poolside. Then the four Coulter women laid down on their backs and their respective partners started fucking them side by side in a missionary position.Susan went around and started taking pictures with her Polaroid. I began to disrobe as Heather laid back on the bed, and spread her thighs in my direction. I could not take my eyes off of her. She was simply beautiful, and my cock was now rock hard. Once I was fully naked Larry told me "watch all you want, but don't touch your cock"Larry then joined Heather on the bed, and started licking Heather's pussy. I walked around the bed to get a better view. Heather looked at me and smiled, but that didn't last long as she soon became occupied with Larry's oral. Started like 3 years ago and my parents thought it was just a phase and Penny thought I was just trying to get more attention from our parents. But when it continued after a few months everyone just accepted it and don’t pay attention anymore.Even though my body changed some since then but I have a toned body which is pretty good to look at with 34C breasts and 32 waist and toned heart shaped upside down butt with a wide heart shaped thigh gap. Which I have got compliments from boys and girls..
