I met Kat at work two years ago. She was 22, 18 years younger than I, but we had a connection from her first day. I was the owner at a small ad agency, and she enjoyed flirting with, and later dating the boss. She was so pretty and alive, with an amazing body. She didn't dress slutty, but her curves were never hidden in the sundresses she wore all summer or the sweaters she wore in the winter. Things moved fast, she had moved in with me after four months, and I married her 6 months after that.
We were very into each other, but didn't have many common friends. She would come out to business dinners and get-togethers with other couples I knew from time to time. Kat was a good sport, but my friends were a little staid for her. I felt a little out of place when 'd go to parties her friends threw, although there were lots of hot girls prancing around. More often I'd keep her to myself or have her go on her own.
One night I did agree to go to a party celebrating her best friend's engagement. Instead of a bachelorette party, it was guys and girls, and I could tell it was going to be a little wild as soon as we walked in. Her friend, a petite Asian girl hugged me tight when we arrived and handed me a shot. She introduced me to her little sister, Aimee, who I had actually met once before. I quickly found myself separated from Kat and sitting on a couch with Aimee. Aimee lit up and shared a joint. She was very touchy as we talked, and casually draped a bare leg draped over mine as she lay back and listened to me tell a story as we smoked. She had a tight little body, very different than Kat's. No tits to speak of but beautiful legs and a small pert ass. I felt myself get hard as I felt her leg on me and she teased about how much she liked older men. She told me a story about how she had seduced her teacher at a party on the last day of school, how we had hiked up her skirt in a back room with everyone just outside the door and fucked her. I was getting incredibly horny, and when Kat came by later she saw Aimee nearly on my lap with my hand on her leg. She gave me a dirty look as I casually shrugged. I hoped she didn't notice my hard-on through my pants. Later in the evening I found myself making out with Aimee a bit in a corner, my hands on her ass while her hand slid down and grabbed my cock. Through the haze of the drinks, I realized what I was doing. I was pretty sure nobody had seen us, and I extracted myself and returned to Kat.
When we got home later Kat started to give me a very hard time about flirting with Aimee in front of everyone. I protested that she was drunk and I didn't do anything, but she said I was clearly flirting with her and it had made her look stupid. She asked if anything had happened and I emphatically said no, but I felt she could see right through me, or knew exactly what had happened. She asked how I would feel if she acted like that with my friends and I said it wouldn't be that big a deal, after all it was just a little flirting. She made me agree that the next time I had the guys over for Sunday football, we'd see how I felt. She would be allowed to flirt and tease as much as she wished, and I could only say yes to whatever she asked me that evening. I stayed awake a while that night, feeling lucky I hadn't lost Kat, but wondering what she had planned for Sunday.
I had watched Sunday football with the same group on guys since college. We rotated houses to avoid pissing off the wives. It was nothing crazy, but there was lots of beer consumed and the conversation was often more than a bit off color. Kat generally avoided the group, sometimes watching with us for the first half, then escaping after the boys got a bit drunker and rowdier. All the guys lusted after Kat of course. She was so much younger and hotter than their wives or girlfriends.
