My wife Jen is very outgoing and friendly, she hasn't met a huge cock she didn't like. She is gorgeous a red head with hair passed her shoulders, 5'5", 110#, 36d, hourglass figure. We were out with friends for some social drinking and dinner at a nice tavern. After a while we were talking and dancing when one of the other wives said look at the crotch on that guy. We all looked where she pointed out this guy standing at the bar drinking, he had a huge bulge between his legs. Jen said how would you like to fuck than guy? The wives laughed but one of the other husbands dared Jen to dirty dance with him. Jen was not one to back down and accepted his dare. She walked up to the guy talked to him for a minute then accompanied him out onto the dance floor. It happened to be a slow dance so as they were dancing Jen made sure to rub up against the guys cock, he grabbed her ass pulled her tight against his pelvis and they ground their pelvis into each other, he reached up and started to fondle her breast. I could see Jen was getting worked up. The husband that dared Jen asked just how far will Jen go with this guy? I said seeing how hot he's got her probably all the way! He said in disbelief No she wouldn't. I said we'll see.After they finished dancing they walked out behind the tavern and we all followed them. They stopped in a secluded area and began to undress. Then they were making out with naked body's against each other. We all watched in exotic fascination as Jen took his huge cock n her mouth, he looked a good 10" long and thicker than a beer bottle. She sucked him for a good five minutes. He then sat her on a car hood and went down on her pussy. She had a climax after after only two minutes. Soon after that he lifted het up onto his cock and proceeded to fuck her standing up. She was so excited that he slid right in. In minutes she was bouncing on his cock and cuming , she said " fuck me good" loud enough for all of us to hear, she was moaning and swearing experiencing multiple climaxes, she was in heaven fucking that huge cock. We just watched , it was so hot, I started to cheer Jen on some of the wives joined me shouting for Jen to fuck him good. This drove Jen over the edge. She had a massive organism, crying oh shit, oh shit! His arms must have got tired as he lowered Jen back onto the car hood and continued to fuck her hard. Jen was yelling Cum in me cum in me. Several minutes later he made a noise and emptied his balls into her pussy. He fill her with his cum. A few seconds later he put his limp cock out of her pussy. They kissed and got dressed. As they approached us Jen greeted us and introduced Doug her new fuck buddy. He gave her his card and left. Everyone was looking at Jen and said said What? One of the guys said I can't believe you just let her fuck a stranger. I said you dared her! He said ya to dance! Jen said did you see the size of his cock?? When he pressed that monster against me on the dance floor I couldn't help myself, I had to have it. I'm such a slut when it comes to big cocks. Did you guys enjoy the show? I said I thought it was super hot, One of the other guys said he was horny as hell from watching Jen fuck. His wife said she wouldn't mind fucking a cock like that and Jen said he's coming over later this week if your serious. A different wife asked if Jen and I did this often, to which Jen said not enough. We all returned to the cars and said goodnight. On the way home Jen said the cheering really got her hot, she never had a cheering section before, we need to do this again.
