Tonight's Experiment

I met her at a conference and we agreed to try an experiment. She was in her early thirties, sharp and willing. In my hotel room, she undressed slowly, then knelt before me. Her tongue traced the outline of my cock, wetting it thoroughly. I guided her head, thrusting gently into her mouth until I felt the back of her throat contract around me. After several minutes, I pulled out, turned her over, and entered her from behind. Her slick walls enveloped me instantly as I started a steady rhythm. We both came hard shortly after.
