I suppose it began innocently enough, I had been reading my Email and read one of those ads to join some sort of "meet your mate" clubs. It said that it was free, so I filled out the application and a long questionnaire about my own profile. I really didn't expect any sort of serious response. They usually try to match you up with some woman who is uglier than sin or some pay per call voice on a telephone, so I was totally shocked when I did get a reply that was rather reasonable.
Somehow they had gotten my mailing address and the next thing I got was another form for more detailed information about myself, but now the questions were of a more personal nature. I had become curious so I again filled it out, and now I was giving very truthful answers, not the lies most often provided on these things.
Age, 39, sexual orientation, Straight, size of penis, eight inches, and it went on and on and I truly tried to be honest, thinking it wasn't going anywhere. One of the questions was peculiar. It asked if I would be willing to participate in a medical study of sexuality. I checked yes, thinking it a rather innocent question. Two weeks later I had a visit from a very attractive young lady dressed in a business suit.
I welcomed her in and she sat rather primly on the chair opposite me and explained that she represented a research facility that wanted to know if I would participate in a new project to evaluate some sort of psychological research experiment. I was really not inclined to go along with it, but being a bit naΓ―ve, I ultimately agreed to go with her the next day for a physical exam. To be perfectly honest, I would never have agreed if she hadn't been so damn good looking and quite frankly, a bit sexually arousing.
The next morning about ten she returned and we drove to what appeared to be a doctors office. It went down just like a normal physical exam. All the usual tests, including a blood test and stress test. The second part of the exam was the shocker. The male doctor told me to take two white tablets then left and a female doctor entered the room.
In a very business like tone she told me to undress completely. I was feeling strangely passive and very much at ease. It's strange, but when a doctor asks a person to undress, it seems perfectly natural, so I wasn't too embarrassed to do as she directed.
Then she had me lay on an examination table and began to do things that were totally unexpected. She seemed very interested in my genitals and as she moved her hands over my shaft and gently rolled my balls in her palm. I began to respond. I am cut, that is circumcised, and as her hand began to stroke up and down my cock she gently squeezed.
My cock grew larger and larger and I was now uncomfortably aroused. She smiled and softly spoke. "It's important that we understand how you react to tactile stimulation as well as your other sensory responses. Your personal profile said that you had difficulty becoming aroused unless you were physically stimulated, and that you stay erect even after ejaculating several times. That's why your considered a candidate for this project."
By now I was at my largest, perhaps eight inches long and quite thick. She had a sort of pleased smile on her face as she continued her stroking and I suddenly heard myself gasp, "No! No more! That's too much."
"No, I have to finish this for the records so just let yourself go and don't try to hold back. It's important that I finish and establish your limits," she replied.
Although I was really embarrassed at this point, I was too far into it to really resist and suddenly I began to feel the muscles across my abdomen tense and my buttocks contract. I was going to cum and nothing in the world could stop it.
I was so engrossed in what I was feeling that I didn't see her place the device over the head of my cock and when I began to erupt I gasped, trying to warn her, not realizing that she was prepared. "Oooh god, here it comes. I'm going to shoot!" I gasped. Pressing my chin down to my chest, I turned to look at her face and saw her intently watching my cock buck and convulse as I erupted. For some reason I lasted longer than I normally do. Perhaps ten or twelve times I felt my cock contract and spew my sperm in thick streams upward.
Slowly I felt the tension go and I watched her slide her finger from between my balls to the tip of my cock, gleaning the last fluid from my shaft. Then she removed the plastic device and set it on the table behind her and quickly returned to my side and again resumed stroking and kneading my cock.
I had been truthful in the survey, noting that I recover quickly after ejaculating and usually maintain an erection for as long as two or three hours before become flaccid again.
Continuing to stroke, she looked down at me and spoke lowly. "Are you really able to do it again? I need to know your limits. Do you need help? Is there something special that will keep you aroused? I mean visual, or physical, or anything at all you need to finish a few more times?"
By her continuing to clutch my cock at its base, I knew I was still erect, but whether I could do it again was the question. Usually when I cum over and over again I'm very stimulated by my lover and the atmosphere, but this was a rather sterile environment and not very romantic. So I told her "I really don't know." I was sort of slurring my words at this point, almost as if I were drunk and the room seemed a bit misty as if my vision was becoming distorted.
As she stroked me I turned my head to the side and saw a very young girl come in and joined her. She was rather tall and had a beautiful body. It was easily defined because she was completely nude and extremely well endowed. Her breasts were perky and she was probably a B or C cup and she had nipples that stood out erect like those thimbles my mother used to use when she darned my sox's
She bent over me and planted a warm kiss on my lips and as she pressed her left breast firmly against my chest, she opened her mouth and slid her tongue deep into mine. I felt myself begin to respond again.
Apparently a third person had entered the room and had dimmed the lights. I lifted my arms and I slid my hands around the girl who was exploring my mouth with her tongue. I let my hands wander down past her waist still lower to her butt.
Cupping the firm cheeks in my hands, she broke our kiss and leaning closer, began to rub her nipple against my chest. The other woman continued to stroke my cock and I heard her whisper to someone else.
"My god he is hard. Look at that. He's perfect. Go ahead if you want but don't swallow." I was sort of in a semi conscious state by now, yet very aware of the sensations coursing thru my body.
