So this story begins when you read that letter I wrote and, after mulling it over for quite some time, decided you might like the idea. Of course, it took a little while longer before we could arrange our little experiment, but I think we'd both agree now that we've been able to stretch our imaginations and quality (and quantity) of pleasure far beyond what we had even dreamed about before.
You remember we had that discussion about those things I thought I valued for their own sake: my daughter, my music, and quality sex. Then you asked for a description of what my best case scenario would look like for consistent amazing sensual pleasure. So I wrote down the basic ingredients. First, I would need a partner, someone like you, who had nearly unlimited libido, an amazing intellect, imagination, commitment to fitness, and was stunningly beautiful. My partner also would have to be interested in both men and women, and particularly in controlling the pleasure of third parties. That last part really made me think that no woman, not even you, would have an inkling to pursue that kind of campaign of recruiting, building trust, training, and ultimately satisfying in an intensely erotic way "candidates" for our sessions.
But you surprised me yet again. You said that if certain conditions ever arose, you might find the idea intriguing. Perhaps you thought those conditions would never arise. I certainly never thought they would. The Divine Muse works in mysterious ways, though, and I positively held my breath when we actually had a chance to try this out. To be honest, I thought you would back out. I certainly wouldn't have thought any less of you. You've been such a fantastic friend these years and such a delicious lover back in the day. I had no real expectations.
