This all started a year ago.My wife and I have a very good love life in that she likes to please me,she went off sex after the change at 54,but she is happy to fuck,suck and wank me whenever I please. Sara's sister Lynne is 67 two years older than me,and has been a widow for a couple of years.Any way on one of Lynne's visits they were chatting in general when sex was mentioned,and Lynne said to my wife how she missed a good seeing to.but didn't want to get involved with anyone because she felt unfaithful.After a long chat Sarah suggested that I could call on her saying that sisters should help each other out.They discussed this over a few weeks with out telling me. I came home from work one day and Sarah told me what they planned and would I like to fuck Lynne knowing I would love to.She told me what they talked about and what I liked and to give Lynne a good seeing to,this made Sarah randy and I was to fuck her like I was going to fuck Lynne.We did and what a fuck. A day was arranged for me to call at Lynne's house,she looked stunning red top black skirt and high heels.We were both nervous and I kissed her on the lips that turned in to a snogging session hands going all over our bodies.She felt my cock and said she couldn't wait to be fucked because she had waited so long,she got on the floor on all fours and pulled her knickers to one side ,she had a shaved pussy,Sarah had told her to do this. I wetted her pussy with my tounge and slid my cock into her she bucked and fucked like a wild thing.After fucking several times in different positions we stopped for a rest,she said not to tell Sarah that she was a dirty slut because she felt embarrassed.Any way we fucked some more and I was to come around any time I wanted . When I got home Sarah said how did it go and I told her we had a good time and I said she was a good fuck and wished I had fucked her ages ago,Sara dragged me upstairs pulled her knickers off and said fuck me like you fucked her. I did but not letting her know to much. I visit Lynne two or three times a week and Sarah's wanting to fuck more also. Now Sarah's more interested in sex she wants me to find her a man to fuck her,she said there's a young guy at work flirting with her and should she give him the come on, I said try it and see.Sarah says if it works out what about a foursome .She's back to sexy dressing and pleasing her pussy with a vibrator . Lynne dresses to please and we enjoy our sessions. Two weeks after the discussion of the young guy Sarah came on to him and they slept together she said the sex was fantastic and he would like to meet Lynne if she's interested,he likes older women.we will see.
