Following on from previous stories about my affair with the M-I-L, this is what happened on our trip to Scotland. I drove there with my wife thinking I was heading south on business and the M-I-L travelled via coach. When I walked into our room I was delighted to see the M-I-L in her nurses uniform with red high heels and bright red lipstick. Suffice to say we had an amazing next couple of hours. But what was to follow was totally out of the blue and unarranged. We'd gone down to dinner dressed quite casually then into the bar for a couple of drinks. We got chatting to a group of couples who were there on a golfing weekend and one half of a particular couple was showing more than a bit of interest in 'my woman'. As I was talking to Martin, I noticed his wife Ann was becoming very tactile and stroking my M-I-L's arms and occasionally, her knee. About an hour later, the M-I-L rises and nods at me to indicate we should leave. So I joined her and we headed out into the garden where she whispers in my ear that we will have company soon. We'd wandered for a couple of minutes then stopped and kissed passionately, then I felt my bum being groped by another pair of hands. As our lips parted I then seen Martin stud behind my M-I-L groping her lovely breasts and my first feeling was one of jealousy, but as soon as I turned around to be met by Ann's lips my rock hard cock told me in no uncertain terms that all I wanted to do now was to fuck Ann. Within a couple of minutes both ladies were bent over with there bare arses in the air and me and Martin with our trousers round our ankles ready for action. The next 7 or 8 minutes were just frantic thrusts from Martin and I as we went at it in unison as we emptied our balls into each others lady. We then returned to the bar to join the others and spent the rest of the evening in pleasant conversation with all our new acquaintances. Upon returning to our room I asked the M-I-L how it all had come about. She told me that she loves me and as we had mentioned certain scenarios such as we had just enjoyed during our love-making, she wanted to make it come true for me to keep me happy. She has also said that if I want to do it again she is more than happy to do so. My M-I-L may be in her early fifties, but she is very attractive and has an amazing body that a woman half her age would be proud of. I've not told her, but the truth is, I love her too......
