The horny shit sphincter was stretched to bursting around her young son's cock, sucking on the veined prick shaft as it stabbed relentlessly into the ...epths of her bowels. There was some pain as his cock burrowed into her asshole, but it was more than compensated for by a delicious pleasure that grew stronger every second. Soon the horny mother was humping fast and hard, whimpering as she held her ass cheeks apart, eagerly fucking her tender, horny asshole onto the satisfying stiffness of her. .." I continued to thrust and said "too late" She gave up very quickly as she was obviously extremely turned on by this point and I continued to fuck her for a few minutes before we both came in the most amazing climax.I climbed off her and we both lay trying to catch our breath. There was an embarrassed silence as neither of us knew quite what to say.........After a few moments, she got up and sorted herself out, saying something along the lines of, "Let's pretend this never happened and never. Yeah, the whole fucking (so to speak) island. It wasn't all that big or anything, just a mansion and some out buildings with servants. We gave them the week off.It got weird there for us. For two days and three nights we fucked. We fucked everywhere on that little island. I had gotten off the pill a month before and this was my time to conceive, so Conception Island. But I woke up that third day and completely freaked out. I mean I hadn't had an attack of any real significance for years, ever. I worked my way up and kissed Rebecca passionately. Unsure but very hot, I pulled my dick out and completely got naked. I heard Gwen say 'God damn' and she kept playing with herself. Rebecca looked at her and smiled before suddenly stuffing my dick into her mouth. This was the best head I had ever gotten from Rebecca and I started sliding my dick deep into her throat. After a while, Rebecca said she needed me inside her. I didn't wait. I spread her legs, kissed her, and started pumping inside.
