Only a few minor events in this story are fictitious, the rest is hard core porn reality. I have wanted for some time to tell of an adventure that resulted from an erotic relationship that I developed with three women in my yoga class. It started in my yoga class some weeks ago that finally I let get a bit out of hand (and I might add out of mouth, pussy, ass, cleavage, armpits, kneepits, clinched shoulder blades and any place a greedy organ can be esconced). I may have told you about this group of three women in the class that always good naturedly flirted with me and I a little with them. One, Sue, I found out was an exotic dancer, another Susan, a desperate housewife, and Cynthia, just a horny broad covered with tattoos. Cynthia repeatedly has asked me to hang out at bars with them and I always supposed she was just teasing, but asking so many times I began to think differently. Then Sue began asking me after class to give her and Susan some private lessons in use of the weight equipment I always went to after yoga class and wondered if I had been as turned on by class description of hot yoga (performed with dry heat above 106 degrees F). I jokingly (half yes and half no) admitted that I would like to try it sometime and then felt guilty for egging her on. If you are not into yoga then you cannot know that many of the poses and postures were designed to help men and women achieve better sexual performance and pleasure and variety in sensuous activities and if you watch their successful execution then you can see why I sometimes get a little stuffed in the sausage at times thinking of a more private use of the poses with some action thrown in. Though I usually the only male in class, occasionally teacher will discuss how some poses will help achieve greater sensation to the female sex organs and how the penis can be grasped with greater orgasmic intensity in the male by employing some of the muscle engagements she teaches us. I usually turn red but in the semi darkness, no one knows how prudish I actually am so I just mutter, right on when the women look at me for endorsement of the comments. So anyway I finally did say I would set up a time where the four us could meet and experiment with the hot yoga. Sue suggested a room at the library that is often used by exercise clubs sounded okay to me and she assured me that the entrance would allow all of us to get there unnoticed by the regular library visitors. I thought a thousand times what an ass I was to think I could do something like this knowing perfectly well what would happen there, but the devil in me took control so I went to the room at the appointed time. Brought two space heaters so up the heat in the room and waited a long time hoping there would be three no shows but they did come and laughed since they knew I would not show up it was then I knew beyond any doubt that these gals meant business and were not playing me for the fool that I believed myself to be (and of course am). Cynthia brought some wine and the three were late because of stopping at a bar before coming so the wine was a welcome loosener for me. Clumsily I suggested some of the couples poses that we had done in class, some of which seemed rather risqué when done with mixed couples as I always had to do in class, but seemed like a good starter as sets of some fairly safe exercises. Susan played her ipod with some very un-yoga type music that helped do further loosening and the increasing heat helped too. I swapped around and particularly like the forward facing shining star where you face partner, both lean in one direction till that arm hits floor with outside leg extended and then lean towards each other till pelvis makes full contact after a few gentle poses we began to use the free hand to grind the hips together and it no more bothered me that I could feel my hardening penis causing twitching in the opposing groin, particularly in that of Sue this was source of more joy that I thought possible but still was troubled by thought that any minute they would burst out laughing and hopefully I would be able to laugh as well. Another blood boiler was a double flank with the bottom partner doing a reverse up position push up pose (facing upwards) and me on top in regular push up position and then undulating from shoulders to groin gently touching the breasts and the groin in what I can only call a borderline porn activity. By then I was down to shorts and my only good fitting boxer briefs that you suggested I get the latter particularly flattering to my nice hard ass and smaller but even more desirable bulge on opposing side.
