I had been watching her expression, and it changed at the same time. Her constant moans and whispered urgings stopped, and her mouth opened wide. Her ...ead went back as her back arched, and she froze that way for what felt like forever. When she loosened up a little, I exploded and entered her fully. She did scream, then.I stayed still as we recovered, and when I could uncross my eyes again, I looked at Denise. She was panting, and moaned "How long until you can do me?"I pulled out and laid. With that, she gathered up some of the filmy layer and began to stroke my throbbing erection with it. Her nipples instantly sprouted to their full extension under the light nylon material. "I think you liked screwing my with my pantyhose on, didn't you?", she asked. Before I could reply, she moved back, and took the full length of my shaft into her mouth. For several minutes, she gently worked her lips and tongue along its length, then to my surprise said, "Lick me !" I pushed her onto her back. When she felt him shoot for the fifth or sixth time, it lit a fire in her and she started cumming with him. Her pussy went into over drive, rippling and flexing on his shaft, coaxing more cum out of him. She no longer held her hand over his mouth, instead she needed both to wrap around his neck to hold herself up while she convulsed on his cock. “Oh. My. God.” she rasped while cumming hard on his dick. His orgasm again almost made him pass out. But then there was a new sensation, her pussy. Although I'm not gay and not the least bit interested in any same sex intimacies - for some strange reason I found myself wondering what that bulge in the front of his pants was all about and what it looked like. Was he long or short, cut or un-cut, thick or thin? As the telephone conference droned on in the background I paid less and less attention to the participants and I began wondering if he was still a virgin or if he had already learned how to make love, well at his age it wasn't making.
