Melanie was a really attractive woman. In her early thirties, about five and a half feet tall. She was not slim, but very shapely with a very full ass, beautifully rounded, soft, shown off wonderfully in the tight skirts she loved to wear. Melanie had been part of our group for some time now, and Judy, my wife, and I had both enjoyed some pretty vigorous love-making with her at different times. She was one hot woman. There was just one problem - if you can call it a problem - she liked to be in charge, to run things. Some would say she was haughty, adopting a superior attitude at times to others. Within our network we don't mind people being dominant or submissive, but we also expect everyone to be valued equally, we expect everyone to receive the maximum amount of fulfillment in whatever sexual activities we get up to. Too often with Melanie she would be so strong and haughty she would forget the fulfillment of the other person, and a few of our group complained strongly about her attitude.
It was with this in mind that Judy and I had planned the afternoon we were embarking on. We had agreed that as well as sex, perhaps Melanie also needed some humiliation, and it was with this in mind we had planned what we should do.
Melanie had arrived an hour before and we had chatted. Judy had told her how hot she was for a bit of woman/woman sex, but that we had found a little toy which would make Melanie's fun all the better - a little device which fitted in the anus and helped with extra stimulation. Melanie was more than happy to have a go at anything. And now she was lying on top of Judy in a passionate 69, Judy holding Melanie's head tightly with her legs wrapped around here, and with her arms holding on to Melanie's legs. It was quite a sight which left me very stiff, particularly seeing Melanie's wonderful full ass bobbing up and down.
Melanie was too involved in her love making to see what I was doing. I had suspended the bag of water above the bed, joined the tube to the bag, and was preparing for the hardest bit - joining the tube to the toy the unsuspecting Judy had put into her ass.
Surprisingly she hardly noticed me joining the tube, so much was she wrapped up in Judy. After I had the tube attached I simply stood aside and waited.
