I did it for around 2 mins, enough to shake her brains out.Both of us were in no mood of stopping. My cock had been in her for almost 20 mins now and ...there were no signs of either her cumming or mine. Again she started jumping over me. It was a very different type of ride. We were almost drained out of energy, but there were no signs of stopping. She said, do for 2 more mins…I will be out by then. I turned her around with whatever energy I had and started my last dip.Inserted my cock in and. .. well, those women did not look normal. It was like a spell had been put over them and..."My heart pounded in my chest. "I invented something. Or discovered it," I told her, holding my hands tightly together. "That when particular energy is fired at women, it causes deep and uncontrollable arousal for around an hour, and my friend thought that they would use it and..." My voice trailed off as I mumbled and looked at the classy girl, gauging her expression as she fiddled with her hair."Don't. Needless to say, I was turned on by the possibility of having my first black cock to suck and fuck. I was hard thinking about being naked with him, my pale white skin against his dark hued body. I wondered if the myth that black men were all well endowed would become a fact for me.We decided to get together at my place. When he showed up I was very pleased with what I saw. He was 6' 3", well built and stocky...nice to say the least. We made small talk for a while then the sexual tension got to. She said, “Your procedure is waiting. You seem ready for it.” She then put her top back on and we went to Exam Room 8.As we entered, I saw that Mrs. Wilson was seated on the Exam Table in just the gown. I greeted her, “Good day Mrs. Wilson. How are you today?”“Just fine, Doctor?” was her reply as she saw I was young.I washed my hands and put on the latex gloves. “Nurse June will you help Mrs. Wilson into position?” I got the speculum and put KY jelly on it and my gloves. I moved into position.
