We had a new year party a few years ago, booze was flowing pretty good and most of the guests left except my buddy Bob. My wife and I had another beer with him and decided it was late, he shouldn't drive so he was going to crash for the night. The kids were at grandma's so we had a spare bed. My wife always thought he was cute and there was plenty of flirting going on. After I was asleep I felt her get up and saw her go to across the hall where Bob was. I was surprised she left the door open but we had plenty to drink and I had a clear view. She woke him up, sat on the bed, they were whispering and soon making out. She slid the covers down and started suckling his cock, it took awhile to get him hard but once she did her nighty came off and she climbed on top and guided his hard on in. It took a little but once in she rode him for what seemed like an hour. I heard her cumulative at least 3 times before I could tell he was exploding inside her. They collapsed for awhile then she kissed him and came back to bed, closing the door. She climbed into bed, woke me up and whispered that she was naughty but my friend Bob had a big dick and she was ready for more. I rolled her over, my dick was rock hard watching them and slipped into her soaked stretched out pussy which felt great. I didn't last long and filled her again. We all got up in the morning, took showers and had breakfast, not mentioning the night before. Bob left, we cleaned up the party mess and had sex again before picking up the kids and washing the sheets. This wasn't the last fling with Bob but that's another story.
