Several decades ago when I was in my twenties, I spent a couple of weeks at a major university attending a post graduate professional course. There was an extremely hot gal in the course who arrived a day late and ended up in the same study group that I was in. Over the course of the next ten days we spent time working on case study problems in our work gruop of about eight people and one evening the group decided to go to dinner, and as luck would have it they chose a restaurant that Mary (not the real name of course) said she absolutely hated, so a smaller group decided to go someplace else. Since she was truly hot, and I have always been omniverous, it was not difficult for me to decide which group to join. A few days later, on the last evening before the 6 hour exam at the end of the course, our small group was going out again and at the last minute some people decided they should study rather than drink wine and eat pizza, so Mary and I (both married by the way) went on our own. We had a nice time and as we rode up on the elevator back at the dorm, I figured I was going to do some review work and get a good nights rest. We were staying on seperate floors and as I was about to get off of the elevator on my floor, she pressed the "open door" button on the elevator, looked at me and simply said, "do you fool around"? About three minutes later I was knocking on her door. We had an amazing time that evening, but to the real point of this thread, that woman (she was in her late 20's) had the most incredible muscle control of any woman I have ever been with. We both enjoyed oral exploration without any boundary. After I came the first time, she simply kept her legs around me and squeezed my cock as if she were using her hand---her ability to grip was absolutely undulating and she could vary the pressure in amazing ways. She revived we quickly and for the next several hours and through multiple positions I think she had hold of my cock with her pussy for all but maybe 60 seconds in total during that time. I quit counting after I had come six times and we totally soaked the sheets She was also the first woman I was with who could ejaculate (she had her first orgasm while I was eating her and the viscosity was totally different than urine) and when she was cowgirl in round two she moved very slowly until I came, and shortly afterward I felt her spasms and then our combined cum spread over my ball sack and down my ass. It was an amazing time but we never saw one another again. Mary did have a snapping pussy. I know I will get flamed by some who will say this is BS, but it is a true story. I sure as hell wish I could do now what I could do that night.
ive had one girl friend who had the ability to use her vaginal muscles to fuck my cock...i hardly had to move at all when we were fucking which was all the time...(i was in my late 20's). she was also incredibly kinky to the point of being into stuff even i wasnt willing to explore...(electricity to her nipples, extreme pain) but when she was fucky fucky...it was unforgettable ...
