I'm not the cheater. My wife is and it turns me on more than any other sexual experience. It all started just a few years into our marriage. She started going out with her girlfriends to the dance clubs. I was worried she might hook up with some guy. The more I thought about it, the more the idea turned me on. It was only a few weeks into her weekly dance nights that she started dressing sexier. Her make up got sexier as well. It was obvious she had either met some guy or was trying to. My initial reaction was to say something to put a stop to her weekly nights out. Something stopped me. I wanted to see what would happen. Sure enough, one night she called me just before her time to be home. She said her girlfriends wanted to go to another club and wanted to know if I was ok with her going along. She went. The next week she wanted to know if I was ok with her going out a couple of nights. She started going out a couple of nights a week. The next thing I know she's going out three nights a week. Of course her nights out got later and later. At this point there was no doubt she was sleeping with another man. Not only did I not try to stop it, I encouraged her going out. Hell I even started helping her dress for the evening. I tried not to be to obvious, but I would suggest things I knew would make her as sexy as possible. Things I knew would get a man turned on. If she knew what I was doing she didn't let on. After she would leave for the evening, I would masturbate like crazy thinking of her being with another man. I would pretend to be asleep when she got home. Partly so she wouldn't have to explain why she was so late, but also to watch through partially opened eyes, as she undressed. I wanted to find her panties the next morning while she was sleeping to see if there was any concrete evidence of her having sex. Sure enough, it was obvious. Then one night when she came home ,she did something she had not done before. As she undressed, thinking I was asleep, she leaned down and kissed me. I immediately smelled and tasted another man's cock. Now most men would have been furious, but I got an erection. The idea that my wife had just sucked another man's cock probably not more than an hour before was such a turn on. Her affair with this guy lasted about two years and I never tried to stop it. If you can believe this she ended it by started to sleep with yet another guy. The first guy got jealous and tried to ruin our marriage by "telling" me about their affair and the other guy. You can imagine his shock when I told him I knew the whole time about him. I just didn't know who he was. As it turned out he was a tall good looking older man. I could see why she was attracted to him. He was right up her alley. As far as the other guy goes, she stopped seeing him almost as quickly as she started seeing him. The first guy called her to let her know he told me. Of course I had to pretend to be jealous. She would not accept the fact that I was not only ok with her having sex with another man, but turned on by it as well.
This all happened about 10 years ago. To this day I think what gets me the most excited is that my wife is a gorgeous woman. She was one of those women when she walked into a room every guy in the place turned to look at her. You could see the desire in their face. She still has that effect on men. The idea that another man was enjoying her sexually at her physical peak is an enormous turn on.
Even though we're older now, I'd like her to do it again.
