I pushed in deeper and deeper grinding my pelvis against her writhing ass. Unexpected to her, I reached around her hip and started playing with her cl...t. I pinched her nub with a bit of force. This made her jump and squeal. Again, like a lightning bolt through her body she began cumming very hard, so hard in fact that I felt wetness on my thighs. I just smiled knowing that she just squirted (one of my favorite things to get a woman to do). “WHAT DID YOU JUST MAKE ME DO? I’M CUMMING SO….SO….SO….. I guess it was about fifteen minutes before I had finished and walked into the living room. When I got to the doorway I stopped. There was Katie on her knees, with her dress in a pile on the floor. They were on the sofa and her dad's pants were down to his ankles. Katie had his nice thick cock in her throat and was bobbing up and down on it. I stood there watching for awhile as Katie's dad stripped off his clothes and she continued to suck his cock. My dress was up around my waist and I had two. This clearly amused him and for several minutes there was nothing to be heard but the guests’ slight chuckles as he squeezed tightly and her intake of breath as she took his cock to the back of her throat.His fingers moved upwards on her breasts and he squeezed her whole breast in his hand. This continued across and round her breast and she knew she would have finger mark bruises for several days later. Again she heard his voice this time telling her to take this enormous cock fully down her. But, it was done. It was history. It was then her standard, as a minimum, when I dated her and then married her. I learned that during our own first experiments.We decided to start swinging so that “she” could have the experiences that were more normal, for her. But, then that is when we ran into the reality that my critics describe well. Most swingers accept the length and width averages. But, because of the very first penis poked into her, my wife was a “size queen”. Nothing to be ashamed.
