." I moaned as I felt his cock spread me open! I got up on my toes to adjust as he continued to slowly push! My body tensed from the pain of my asshol... spreading so much but he gently held me there until he got all of that cock inside me. I could feel the size of it and he held it there. He whispered "are you okay?" and I moaned back "yes!" as he left his cock in me to get me used to it and molded to his big cock. After a few minutes he began to slowly pull back then push into me again very. "Oh my God!" Charlotte said in admiration as she showed us into the house, "If you want to go anywhere Derek, you can leave Cathy with me darling, I'll look after her" You look kind of edible yourself Charlotte" Cathy said as my sister kissed her on the lips, "And I'm hungry"I stood and watched as they shared the same breath, as Cathy reached for the spaghetti straps on my sister's shoulders and slipped them down until only Charlotte's arms around her neck prevented the dress from sliding down. I pulled her out onto the dance floor. She had some good moves, but they were a little out of date. She'd been out of the game for a while, I figured. Still, she wasn't afraid to shake her tits or wiggle her ass, and she didn't pull away when I started dancing close enough feel those wiggles through my slacks.I moved around behind her, and put my hands on her hips. I could feel the heat rising from her body. I gave her a little kiss on the neck and said, "Let's go."We took my car over to her. I stared down at my sexy companion, enjoying how close her face had now moved toward my cock. I was sure nothing would ever come of it, but that doesn’t mean that I didn’t enjoy the fantasies that were flooding through my head. I started wondering if she was very sexual? She was delicious looking; she had to have had some young stud work to steal that virtue of hers. Did she suck cock? Her lips were perfect. Come on now, you know what I’m talking about; those perfect plump lips that you can’t.
