My wife started working for a greyhound trainer he was a bachelor and lived a few minutes walk away from us, I did a bit of maintenance around the kennels for him I noticed the way he looked at her as she was bending over in her shorts it was obvious he was interested in her, he was 15 years older than her and not much to look at so I didn't think it would happen even though she had had other men for a large part of our marriage, she needed 4 new tyre's for her car and as work had not been good for a while I told her we couldn't afford them she said she would get them somehow, long story short she fucked the greyhound trainer for them and went back the next evening to fuck him again, I soon found out why he had a much bigger dick than average it was very very thick round and she loved the way it stretched her cunt she fucked him 4 or 5 times a week at one time and I was struggling to get a look in, sometimes I would be told to cut the paddock by her while she was in his bed getting fucked by his big cock or to do some housework while she went to his bed for a fuck she had him for a lot of years with others in-between.
