This was an additional sexual thrill and something that she had not had before and she was wild with lust as she rode his cock bringing her to orgasm,..."Oh, God, fuck, oh, oh fucking hell," she panted as she came and as her arse descended this time Richard's thumb actually entered her anus.Richard was both amused and thrilled by the pleasure that Margaret was getting but he now realised that his prick was about to spurt and he groaned, "Oh shit," as his spunk rocketed upwards into Margaret's. (she used to let me watch her)Anyway, at some point she suggested we all meet up so we went out to a pub in the town. When i was talking to him i asked why he turned down the opportunity to fuck and he just shrugged and said the furthest he would have gone was watching her perform live. I told her this when he was at the bar and she said she would have been happy with that, he should have asked. After a few more drinks i raised it again when we were all there and he said he would still like it. It was more like the ocean breeze that molds the sand into dunes: inexorable, insistent, but so gradual you don't even see the changes.It was *him* that started the exercise program. It was him that urged her to increase her sexual activity with me. It was him doing all of that, behind the scenes, until that fateful day a few weeks ago when it was all presented to me, the deal all closed, with only one loose end. I had only one choice left to make, and I keep making it every minute of every. He gave maybe a dozen small thrusts before he sunk half of it in, taking me by surprise, it was like being a virgin again, and my pussy gripped it like a tight glove, bring a loud moan from Martin, I sensed he was getting to the point of no return as he built up a rhythm, he reached under and squeezed my breast pulling on the nipple, he groaned as the thin milk dribbled between his finger and in a instance sunk the entire nine inches into me. I threw my head back in Ecstasy as I met his.
