I felt very exposed and I could even feel the cold draft on my cunt lips. “What a pretty pussy you have,” she said while lowering her head. “Th...nks,” I managed to mumble before her lips touched mine. I tensed and for a second I thought of pushing her away but then her tongue found my clit and I moaned as my body relaxed. She spread my lips and ran her tongue down my slit and then up to my clit again. When she sucked on it I moaned louder and lifted my hips off the sofa. “Am I doing it. She confessed that she felt great doing all that. With that I pushed my cock head in her asshole and started fucking her slowly in and out, in and out. It did not take much time and she began matching the rhythm and or pace of thrusting increased multifold. In the next 30 seconds, I was fucking her much harder and faster, pumping the deepest in her ass. My balls swayed like a pendulum of a grandfather clock with each thrust in her. Then I reached under her and began to rub and squeeze her. ”She snapped back “Trevor don’t talk that way, that was a mistake and I am very sorry for letting it get out of hand. I shouldn’t have ever let that happen. Consider it a one and done. I am married and, anyway just let that be the end of it.” "Well Mrs. C the way I see it we were consenting adults and the only one who has anything to lose is you!" As Trevor gestured with his hand around the house "all this shit might be gone if Mr. C found out-don't you think." My wife glared at him and sternly. It was undoubtedly the best orgasm she’d ever had. And it didn’t seem to calm or slow down at all. As her sister fingered more, she came more, until her sister stopped, then her orgasm did too. She was sad but relieved, and suddenly overcome by a feeling of unearthly tired she’d never felt before either. Her sister collapsed onto her, their eyes closed, a consensual feeling of completeness.And as they drifted off to dream land, her sister said something she had many times before, but for some.
