I remember once waking up one night and finding that my (first) wife was absent. We had picked up my old college buddy, Michael, at the airport earlier that night and had gone out to eat at his favorite restaurant in our city and returned to our place for a quick threesome. I had to work the next day and they would have the day to themselves, so I made him ...... in our living room on a fold-out sofa. This was the only logical thing to do, as we would have otherwise fucked the night away. (He and I are very competitive.)
She and I went to ...... in our bed and quickly fell asleep. So, I was surprised to find her missing, when I awoke I the middle of the night. I quietly got up and looked into the living room. There they were, him sitting on the sofa, his feet on the floor, her straddling him, his cock deep in her, while she silently fucked him. I could see almost nothing because she wore a large blanket over her body and the room was dark. I watched for a good two or three minutes as the blanket move up and down. But I could tell that he was getting close, so I hurried back to bed. I was sort of upset. Couldn’t they have waited until morning, when they would have 8 hours to fuck in? Amazingly enough, I quickly fell asleep.
In the morning, I got up quietly and prepared for work. She came out to greet me and I told her about what I had seen last night. She was distraught and she apologized sincerely. Not for fucking him, but for waking me, as she knew I needed my ....... I was no longer upset; in fact, I was quite turned on by it all. I gave her a big kiss and told her to make him as sexually sated as she could. Later that night she gave me a superb blow job. Mike also got one. She was just too sore to fuck anymore. God, those were good times.
