I have been married to Lyn for 18 years and love her dearly,but for the last 2 years have been having sex with a man who lives close to us,he is divorced and in his mid 50s.It all started just after his divorce Bob and I had been having a drink over at his house and he was saying how lucky I was to have a wife like Lyn and how pretty she still was.Hearing another man telling me that basically he fancied my wife suddenly started turning me on and I felt my cock begin to stiffen,Bob must have noticed my erection and the next thing I knew his hand was on my thigh and he was undoing my trousers my cock sprung free and Bobs hand was slowly rubbing it.This was the first time another man had touched me and I was loving it,I closed my eyes as he gently rubbed me then asked him what he would do to Lyn,he told me how he would undress her and play with her pussy then fuck her,I felt myself beginning to come and looked down as Bob's mouth engulfed my pumping cock.As I sat back panting I watched as Bob released his own hard cock and wanked it before releasing thick blobs of come. Since that night we have sax about once a week and he uses me as his wife and now fucks me regularly which I absolutely adore especially when he tells me he would love to fuck us both,perhaps one day it may happen.
