When my ex was about 26 she told me of an older guy (mid-forties I would think) who kept hitting on her at conferences. He was something of a big wheel in their profession. He had a reputation of hanging out in the hotel bar and hitting on the younger women, so the ex would have known about his behavior, as well presumably as his performance in bed from those other girls. What transpired I only learned of a good time later: as with all the other cuckings I took from her, it was all behind my back, and I was very good at denial about the evidence there was.
At one of these conferences she was in the bar one evening, which is odd because she doesn't really drink. But of course he hit on her again. For whatever reason, she decided that this time she was going to let this guy make a cuckold of me. Although she said nothing of the elevator ride up, he must have started on her, because as she described it, he began undressing her by the time they got to the door of his room. In the short distance to the bed he got her jacket, blouse and bra open to feel up her breasts. At the bed he pushed her down on her back and as she described it "he had my stockings and panties off in a flash." In his lust to get in my wife's pussy he didn't take the time to fully undress her, and began plowing her with her jacket, blouse and bra still on, though open up the front. Fortunately for her his lust did not impede his performance, and as she described it "he fucked the hell out of me," including at some point finally getting all of her clothes off.
After he finished he continued to lie next to her kissing her breasts, until in short order, he popped another erection. He rolled her over, pushed her legs apart and entered her pussy from behind. She never commented on which position she liked him best. As I said, I only learned about this some time later, in the normal fashion of when she let some guy make a cuckold of me, by hints and taunts. Although I probably don't know of all the cuckings I got while I was with her, this was the one where her lover was her senior by the greatest number of years.
