Not that I hadn't shown him before, of course, several times in fact, but I felt an unwelcome, uncomfortable sense of possession I'd never experienced...before as I heard him groan and Isabela chuckle in delight as he filled her completely.The two of them were immediately lost in a tangle of grasping limbs and erotic sounds, and despite my worries, I felt myself harden at the image; I wanted to be pleased that at least little Zev knew what was what in this erotic scenario, but couldn't help but. It was the later that stirred my own inner feelings, hearing my mother beg for it, it's hard to find the words for it, perhaps I have something inside me that she has passed on, but it triggered a response I know most girls my age would find repulsive, I got up and watched them.From my previous recollections, most of you who read my accounts will already know I come from a sexually open family, and I was seeing stuff long before my menstruation kicked-in, so that when it did, I was already. "Baby, that was hot as hell." I thought of something else to make you feel real good, too," she grinned before mounting Kris' cock."Jesus, you fuck a guy on top?!" he asked, both surprised and totally delighted."You like this? Does Trina do this to you?" Not for a long time, baby," Kris panted as Tracy had his entire throbber in her surprisingly tight snatch, bouncing up and down. "Ohhhhhhhhhhhhh, Kris!" she cried. "Your cock feels so good in me! Oh, Kris, fuck me!" Ride me, Tracy," he panted. He was going to fuck her, she thought as she took a deep breath and exhaled, relaxing her tight hole in case he wasn’t gentle. No, that can’t be, she thought, she is too high up for him to do that. She could hear him ruffling in the brown paper bag again, but she didn’t look back as she was instructed not to move. She felt his tongue back on her pussy, very wet this time but it was brief. He took a finger and slowly slid it into her. “mmm” she moaned and pushed back showing him she was ready.
