A few months ago, my wife and I went to London for a long weekend. I begged her to wear a sexy outfit, and she obliged with a short black mini skirt, black leather boots and a skimpy dark blue G-string underneath, and a white blouse and bra. We were dancing in a dark crowded club when she told me that several guys had run their hands over her ass when they passed, and one had just pulled her skirt up and rubbed against her flesh when he passed. I laughed it off, but from then on kept positioning her to be felt up by more guys. The night went on like that for a while, and she seemed oblivious to the attention. She relaxed in the crowded room enough so that I could run my hand up under her skirt and finger her inside her G-string. I brought her to a few climaxes and she kissed me very passionately. We kept the drinks flowing, and soon she was very drunk - not passed out, not sick, but just completely into the music and downing drink after drink. I stated slowing down the drinks, and went to get her some water. When I came back, I found my wife dancing with another guy. Instead of breaking them up, I just watched, but he caught my eye and was about to leave when I nodded my head in approval. From that point on, he got very bold. He immediately put his hand under my wife\\\'s skirt. She didn\\\'t object. My thinking is that he witnesed our activities earlier. His hand started pumping under her skirt, and I could see her knees buckle a little from an orgasm. He continued pumping until he brought her to a total of three orgasms. After a while, the guy moved behind my wife and they continued dancing. They were going at it pretty hard and it was very dark, but I could tell they were grinding very hard and her skirt was up above her thighs. My wife was showing a little bit of her panties and making no attempt to adjust. I was somewhat surprised, but just kept watching. They carried on for a second song, with the guy pawing at her panties from the front while grinding on her form behind. Some people would occaissionally look over their way, but no one did much in this sort of place. There were a lot of people dancing that way by this time fo night. After the latest song ended, the guy turned her around, kissed her deeply, then turned to walk away. Just after he left, I walked up to her and she said \\\"There you are, I wondered where you went!\\\" Her words were slurred and she was very tipsy. We started to dance again, and again I slid my hand up her skirt. \\\"You still want more?\\\" she asked with a little smile. My hand reached her crotch, and both her G-string and pussy were a slimy mess - her cum was everywhere! The guy must have massaged her juices everywhere during their dancing. Some fo the guys around us stared at us now, and whispered back and forth to each other. Lot much later, we decided to call it a night. We took a taxi to the hotel and my wife fell ont the bed, laying on her stomach. I kissed my way up the back of her legs and began kissing her bare ass cheeks as I raised her skirt to her hips. She was sighing with pleasure and completely submissive. \\\"Tonight was unbelievable,\\\" she said, \\\"I can\\\'t believe we did that.\\\" I continued to kiss her and then began to pull her G-string from her ass. As the string came from her ass crack, what heppened struck me. On the middle of the string, just about where it would have lined up with her ass, was a white gooey smear. I pulled the underwear to just below her ass and spread her legs, allowing her ass cheeks to spread. There it was - slowing streaming out of her ass was cum from the guy that she had danced with. When he had turned her around, it was to stick his cock up her ass. And right then I knew what the guys in the club were whispering about - they must have known that my wife was being butt-fucked, then realized that she was actually with me! As I pulled her legs apart, she asked \\\"Do you want to do me in the ass again? You can if you want to?\\\" We have anal sex occassionally, usually with lubrication, so it wasn\\\'t completely unusual for her to let me have anal with her, but twice in one night was a first - especially when the first time that night was with someone else! I had the best sex with my wife that night. I flipped her over and fucked her pussy for all I was worth. With very little time in between, I turned her over again and add my own load of cum in with the other guy\\\'s. To this day, she doesn\\\'t know another guy screwed her in the ass in the middle of that club.
