My wife does more than dancing

I was out on the town with my wife. We went out for dinner, then we hit a couple bars. She likes to dance, so we went to a blues bar: live band, large dance floor. 
Now, I'm not one for dancing, but she doesn't mind. Usually she just dances on her own, and once and a while she has to put up her guard with guys. For her, it's worth the hassle. She really enjoys it when I watch her. And, If there's no one around to talk to, I love to watch her move her body. As long as I don't look like a creep.

I was sitting at the table with a couple friends I met. I got up to go to the bathroom. On the way back I wondered to the dance floor. Some guy had kept her interest enough to get a conversation going. Most guys try. I imagine many think of what they would like to do with her. I'm sure she loves the attention. I think that's why she dresses the way she does. On this night it was pretty simple: short skirt and a tight t-shirt. When she move the right way, your could see the top of her stockings and the straps of her garter. Both were white. 

Shortly after I got back to the table, she joined me. When my friends went to get some more beer, she told me she was going to go for a walk. After she finished her drink, she left. It was quite a while before she came back, most of the bar had cleared out, including my friends. We lived pretty close, so we walked home. 

On the walk she told me she had something she had to tell me. She said she went for a walk with a guy from the bar. They were just going to smoke a joint. 
"I think I have to tell you what happened."
I agreed.
"We went out back and walked to the parkade. He told me about how he doesn't get to meet many girls, especially pretty ones. I guess I liked the attention he was giving me. I told him he shouldn't have any problem meeting girls."

"He showed me his car. He asked if I wanted to sit inside it. We did. Then he leaned over and kissed me. I didn't know what to do, I was a little excited. I told him we could only kiss, because I'm married. He seemed fine with that. We kissed for a while. Then he asked me a question. He asked me how much he could pay me for me to suck him off. So, I gave him a ridiculous amount. I told him five hundred dollars. Without hesitation, he agreed and started undoing his pants. Before I could say I was joking, his half erect penis was in front of my face. It was the first time I had seen another man's cock in so long. I reached out and touched it. It started getting harder. I thought mabye he would just come if I stroked him a little. So I did. The he said "Come on, put your lips around me, I wanna fuck your mouth.""

"I leaned over and slid my mouth over his cock. As much I as I tried not to like it, I really did. His cock was getting hot in my mouth; I could taste his pre-cum on my tongue. Then I felt his hand on my thighs. And I thought "I'm not wearing any panties." His fingers touched my pussy and his found out how wet I was getting."
"He asked me if I wanted him to fuck me. I nodded, still sucking his dick. He told me to get out of the car. I did. He told me to bend over the trunk of the car. Right now I didn't care if anyone saw me like this, I just wanted to get fucked."

"He stood behind me and slowly slid inside me. It felt so good. I must of looked like such a whore, bent over a car with my skirt flipped over my ass, being fucked by somebody who was paying for it."

I told her I didn't believe her. I mean after all, we've been married for five years without any extra-marital distractions.
She reached into her purse and pulled out five hundred dollars in cash.
"And, I'm going to met him there again next week."
