Our ages were not that far apart and it was no problem to think of her as a girlfriend. I had only felt up a couple a girls so far, so I was getting a... horny as mom was. I kept saying to my self that nobody could see us and would never know….she was like a girlfriend I was making out with. I started feeling her tits real careful. She said her dad and her use to dance in the fort he built for her and….then she stopped and pulled me real tight to her and pushed her pussy in tight against my now. "I'd better go, don't want Kerry wondering where I've got to," she said as she pulled on her jeans and T-shirt.I suspected I knew exactly where Kerry will have thought Paula had got to, but held my own council on that.I quickly cleaned myself off and had a shave and was getting into my smartest and newest outfit when there was another knock at the door. It was Kerry..."Hi Uncle Dave, got a minute?" she asked."As long as it's not too long," I replied. "Party in about half an hour." Oh, I suspect. Her head seemed to be reeling and she was glad that Jean was helping her, as the dress was tight and close-fitting. But when it was finally on, it looked as if it had been molded to her body. Jean wouldn't let her wear a brassiere, and the low, deep "vee" in front emphasized her voluptuously full breasts. There was a split, almost thigh-high in one side and the shimmering material sparkled and glinted as she moved. Jean wouldn't allow her to wear panties or stockings, either, saying that unless. I lay down on the bed and she proceeded to unzip my trousers,releasing my already stiff cock.She then stood up and removed her tight jeans.She had on a skimpy pair of panties which she then removed revealing a nicely shaven pussy.She the climbed back onto the bed and proceeded to straddle me before easing my cock into her shaven pussy."bloody hell.You don't mess around do you"."Not when i am horny and in need of a good fucking".At this she began to ride up and down on my ever stiffening.
