In previous chapters I have recounted the events of my 36th birthday, and the adventures with Martha. There are wonderful memories of other times with Diana's friends that will make up the contents of this chapter.
One day Diana informed me that she had invited some of her friends over for lunch and drinks, and they would be there the coming Saturday. I thought it would allow me to have a game of golf, but Diana impressed on me that I was a vital guest and that I would much prefer what she had in mind to golf.
The objective of the afternoon was to scientifically investigate my sexuality, as my little eccentricities intrigued her friends. The girls were each given free reign to satisfy their respective curiosities, but I was to remain blindfolded so as not to make them embarrassed about any experiment each one wanted to conduct.
To start proceedings, the various physical characteristics of my penis were studied. Length, circumference, flexibility, and the angle of deviation from straight ahead, the angle from the horizontal when erect, description and location of any distinguishing features (veins, spots, and coloration) were all recorded. It was photographed close-up from various angles, and the outline traced on paper from above, below and from each side. This was all carried out diligently, boisterously and with much banter with me and each other. The blindfold was useless, as I knew each student from their voice.
What soon became apparent was that my cock was being addressed as if was an entity separate from me – like a pet, or a little child. And I was being kept informed of their observations relating to my little friend.
My reactions to various types of slapping, whipping and caning were explored. The amount of induced pre-cum was estimated relatively to assess physical satisfaction, as well as my own comments recorded. I was still quite inexperienced in this pain/pleasure relationship. Even though Diana, and some others, had slapped my penis at Martha's place, the totality of the experience had masked my sense of enjoyment of this specific activity. I found that it delighted me even more than when these actions were delivered to my bottom. But it was the reaction of the girls which delighted me more. They were having fun, and were exuberant, as contrasted with the silent voyeurism at Martha's. They shouted with delight when I reported pleasure, louder if it was intense. The best was when the slapping (or other) was quickly followed by a relieving wet mouth.
By contrast, other punishment to my penis or testicles was painful but not pleasurable. This included the application of clothes pegs, elastic bands, hair clips and other clip-on gadgets. I found the application of a vacuum cleaner tube exhilarating, and Diana made a note to buy a proper penis vacuum pump for future use.
Bondage by itself was of little value, but when teamed with slapping, etc. tended to increase the pleasure due to the heightened sense of vulnerability. It had become quite clear that I was turned on by female domination and the associated feeling of helplessness. But the domination needed to be administered with fun, respect and understanding.
