I told recently about how I was having sex with my friends seventy year old mother, but unfortunately she wasn't able to keep it to herself and told her friend Helen about her newly found sex life with me, a guy the same age as her son David, one night when we were together she admitted to me that she had told Helen about us, Helen was very envious, and had ssked if she could be involved, even if it was only to watch us together. I was less than happy about this situation and lost no time in making her aware of my feelings, nothing more was said by either of us about the subject till some weeks later. While I was visiting her Helen arrived,unusually she was wearing a low cut top showing lots of cleavage, after tea and cakes both women went into the kitchen to wash up, there was a lot of whispering but I could not hear what was being said although I did strain to listen. When they returned Helen had obviously pulled her top lower, I could also see her nipples straining through the material of her top, she was now crossing and uncrossing her legs allowing her skirt to ride up sowing lots of leg, which looked very good for a lady of her advanced years, my cock of course was now showing its interest. Joan had her arm around me and her head on my shoulder, as we talked, the conversation turned to sexual matters with Helen noticing the bulge in my jeans caused mainly by her and to some extent Joan, they both laughed about the situation with Joan opening my jeans releasing my now hard and aching cock, she started to wank it, Helen joined us pulling my jeans down and sceatching my balls, I now had no control over my cock or the situation. As I watched Helen removed her top and skirt, she was wearing a bra at least one size too small as her tits were hanging out of it and small red panties, she looked really good for an older woman, as I looked at Joan I found her rapidly removing her clothes finding that under her dress she was naked. I was now so arouseD that I didn't know where to look with one woman being naked and the other now topless. Joan took my hand and we all went to the bed room. Joan and I got into the bed while Helen relaxed in the chair opposite, pulling the covers over us we started to kiss quickly advancing to having full sex, I felt Helen move from her seat pulling the cover off us to give her a good view of us, as we fucked together WE both looked across at Helen, she was sitting now naked with her legs over the chair arms and her fingers moving rapidly in her wet glistening fanny, her eyes were closed and her breathing laboured and quite noisy, concentrating on my job in hand I felt Joan quiver beneath me, pulling me tightly to her, I soon followed her lead by reaching my peak flooding her with my cum. Looking over at Helen she was still working on herself, we watched untill finaly with a loud scream and a few seconds of shuddering she reached her climax, as she removed her fingers I could see her inner lips hanging down and her engorged clit that looked like a small cock, if I hadn't just cum I think that I would have cum without my cock being touched just by the sight of her.laining I'm sure that I had been set up by these two old ladies, but I'm not complaining.
