A buddy of mine had special arrangement with his wife: when she went on her yearly business convention, she had a hall pass to have all the sex she could. They referred to it as "conventional sex." For almost a decade, she and he looked forward to that week, as she experienced several one-night stands. Oddly enough, when she neared 40, she no longer wanted the hall pass. A year or two later, she took another job with no trips. That chapter of their lives closed.
Sadly, my first wife never went on business trips or to conventions; I did. If I would be gone for more than one night, we had one of her lovers spend the night with her, when they were available. (I used to love the phone calls from her as she was being fucked.) But never for more than two nights with the same man; if I would be gone for four days, as I wanted two (or three) different men to spend the nights with her to prevent her from growing too attached to one of them.
Once we had, however, a three-day weekend scheduled with my good friend, Mike, but my best friend from college called, telling me that he would be flying into a nearby city and he wanted to stay with us that weekend. Panic. I didn’t want to call off her time with Michael, so I told my buddy that I had to drive to far away city to buy something important and he was welcome to tag along with me. He agreed, as he loved long road trips; and Mike and my wife would get the three days to themselves. Mike arrived early Saturday morning, as I was loading up my car. I told him to enjoy her body as if it belonged to him.
At the hotel that night, I called her up and she told me that Mike was eating her pussy; I had to pretend to be bored, as my other friend was eight feet away.
On Monday night, about 7pm, I arrived home. Mike was still there, waiting for me to return before he would drive off. He thanked me prodigiously. That night she recounted all the sex they had. I was surprised to hear her say that it would have been better if I had been there, as I served as something like a movie director or a symphony conductor, keeping things going, making changes, guiding and steering the sex. She went on to say that in spite of Mike owning her favorite cock, three days of constant fucking was just too much, as her pussy would need a few days to recover. A year or two later, her memory of the three days became sunnier, with the bad parts largely forgotten.
