He caught a glimpse of bare thigh and licked his lips.I now realized that I was in the presence of a dirty old man."Ordinarily, you would receive an a...tomatic F.However, I need someone to help me with an experiment. Perhaps, you canredeem yourself and make a passing grade in this course after all." Iasked what I had to do. "Oh, its a simple measurement of sexual responsetime. I'm sure that a young lady with your qualifications could be quiteuseful in my experiment." He had moved so close to me. Ann was now supported by Debbie, them having talked. She told Ann that I’d been distracted and had been somewhere else all day. It was only when we were in the showers had she realised that my heart was with Ann. But for all that, Debbie had told Ann, and the rest of the girls, that this was a man of all men and didn’t really need the school. It just seemed to come to him so naturally and that in her opinion of men she had been with in the past, that they would probably learn more from me that. While we waited, Jon and I had a quick chat about how we felt. Were we really sure we wanted to fuck each other’s wives? There were no mixed feelings on either part, we were both fully ok with what we were about to do. Finally there was a knock at the door and the waiter pushed the trolley in with two bottles of Moet in ice buckets. I noticed my hand shaking slightly as I signed the bill and I remember wondering if this young chap had any idea what was about to happen in our suite.The door shut. I then gulped and licked my lips and took his penis into my mouth and started to suck it, Tom got really excited and started pushing his hips into my face. I could feel him begging to cum as I sucked and licked it. Unknown to us his wife had returned home early. we did not notice she as watching. Tom's cock by then was bucking and shiverng and throbbing as I sucked, getting ready to cum. I made him last a little longer teasing it in and out of my mouth. My saliva dripping and lubricating his.
