The kids were finally out of the house and my wife had lost most of the weight she had gained over the years of active motherhood. We married young and had our kids early so she was only in her early 40's at this time.She was feeling sexy and just getting used to looking good again.
I decided it was time to take my wife out and show her off. I bought her a tight-fitting, short red dress that came to mid-thigh and had a slit up the back that came up nearly to her butt cheeks. That was all when the dress material was stretched out and tugged down. But the stretchy material tended to contract a bit as my wife moved around or even just sat still. When that happened the dress length rode up to a little below her butt cheeks and the slit clearly revealed her butt. I didn't know if my wife was aware of this aspect of her dress or not.
On the night we were going to go out to dinner and dancing I convinced my wife to wear a tiny thong and no hose. We went to a restaurant first. On the way there her skirt rode up nicely in the car until she was showing a lot of leg. When I opened her door for her I got a nice eyeful of the lacey thong covering her neatly trimmed pubic hair. It was going to be a fun evening.
As we were finishing our meal my wife got up to go to the ladies room. Her skirt had naturally ridden up while sitting at the table. After she stood up she immediately smoothed her skirt back down but not before I got a quick glimpse of her bare butt through the slit. The guy at the next table also got a look at it. He continued to watch her walk away from the table obviously enjoying what he was seeing.
We left the restaurant and headed for the club. Inside it was noisy and crowded. All of the places at the bar were taken with more standing two and three deep. Most of the tables were also taken along with the booths. We finally found an unoccupied booth and had a seat. A roving waitress found us within a few minutes and took our drink order. People were everywhere and the dance floor was pretty crowded.
The club wasn't a really fancy place but it wasn't a dive, either. Most of the crowd was in their mid 20s to the late 30s. We were some of the older patrons but not so much that we stood out. Our drinks arrived and on top of the wine we had at dinner my wife was feeling pretty good.
We got up and danced a fast song. I'm not very good at it but my wife moves pretty good. The fast, hip-swaying motions with her hands going over her head really caused her dress to ride up. At first she was careful to keep pulling it back down but as the energy and excitement built she did it less and less often. As the dance went on her dress was rising so high that I could almost see her lacey thong from the front. When she spun around I could see almost her entire butt through the stretched-open slit. The guys around her could see everything, too. My wife was getting a lot of attention.
The song finally ended and we sat back down. Another fast song played but I didn't want to dance to it, I felt awkward and jerky where my wife looked fluid and smooth. She was looking longingly at the dance floor when a guy who looked to be in his 30s came up and asked if she wanted to dance. She looked at me and I nodded. I really wanted to watch her and see what the crowd was seeing.
The guy was a decent dancer and he managed to put a hand on my wife whenever he could, on her shoulder, waist, and hip. My wife was really getting into the dance. Her red dress was shrinking and her partner was helping it as much as he could. Her white lacey thong was peeking out from under her dress in front. Her butt was clearly and almost fully on display through the slit in back. The thin string of the thong in back was invisible in her crack and she looked naked from the back.
