"Well, I tell you what. How about, if I win, I get something of yours that I want," she said, grabbing his crotch in her right hand. Moving her left h...nd enticingly up to her chest, she added, "...and if you win, you get something of mine that you want." Okay," Sam agreed, thinking that he was just one game away from the best lay he'd ever have, "What's the game? Straight? Nine-ball? Carom?" Simple Eight-ball." Evette answered confidently as she strolled over to the end of the table and began. We'd done the same on both days. Met for lunch, feeding me up, permanently hungry now. Robert being kind and gentle. Then squash after work. Robert being unkind and not at all gentle. I'd been lucky to win the odd point. I planned to practice secretly with Barbara and surprise him. Still, the exercise was good after a day in the library. Then we'd walked, damp from the shower, into town to find a place to eat. We'd found a little cafe that neither of us had been to before. It was so good to be. "Fuck yes, fuck my ass, fuck my ass b*o!" I moan with a sensory overload and pick up speed. "I love your ass s*s, it is so tight... I want to cum in you"! She reaches under and takes hold of my balls, massaging them while I pump he ass deep and hard. "Unload in my brother, my ass is all yours"! I loose it and feel my load at the edge as my cock begins to pulsate deep in my "sister's" bowels. "I am cumming, I am cumming, I AM CUMMING!!! OH MY GOD, I LOVE YOU s*s!!!!!" I let out as I empty shot. Even with all the stretching I had done before it was slow going as I didn't want to hurt her. " Fuck," I groaned, "...sooo fucking tight..." She softly whimpers and moans " aaah..aaah..oooh..oooh," and she fights to hold still, knowing I was going slow for a reason. Another shiver went through her, and she moans again, " ooooh..ooooh..aaaah..aaaah," turning her head to the side. " God...you feel so good," she whispered, biting her lip as she slowly rocked back onto me.Finally I had myself.
