I loaded up a blanket and a six-pack. I picked her up, and we drove out to the lake to watch the fireworks. We laid out the covering in the bed of the...truck, talked and drank beer under the stars. After I started kissing her, my hands roamed over her beautiful body. We had made out before, always stopping before we got too far. I expected her to tell me to stop as I reached back to remove her bikini top, but she didn’t.I looked into her face nervously, I wanted our first time to be memorable,. ” Karen urged.I looked at Mum. “It may be the way to get Caroline involved.”My Mum grinned. “Yes it would!” She explained our problem to Bill and Karen and they agreed that if his barbecue evolved into an orgy Caroline could be included!It occurred to me, that a few short weeks ago, planning the debauchery of my sister, with my mother, I would have thought bizarre. Now I considered it natural.Peter smiled, “Group sex with mother and two sisters! Delightful!”I shuddered with degenerate. I shook my head. "I guess I don't understand. You broke up with me for wanting to have sex, yet here you are working in a store that caters to that very thing."She continued to look into my eyes for a moment. I could feel her emotions plummet. She had been elated to see me, to hold and kiss me. Now I was dredging up the past, our break-up most especially. It wasn't because I wanted a fight — far from it. I wanted her, had already made her mine and knew that we would probably end up going at it. "Again," the demand was repeated.Marion's hips were moving as fast as she could now, as she said it again, and again. Each time she called her son's name, she grew louder and Peter picked up his pace."David, David, Awe, Fuck me, David! Fuck me harder! I'm gonna cum! Fuck me, fuck me, fuck me, David you're gonna make your mom cum all over yooooouuuuuuu!" Marion began to shake and shudder and he heard Peter grunt as he started his own orgasm.
