I dated a girl way back in time and her parents loved to dance. After meeting them they invited us to join them on the Friday night dances, occasionally. Found out very quickly her mom was a bit of an exhibitionist, my gf warned me.
When I went to pick up my gf, I found she and her mom were rushing around finishing getting ready. I wasn't used to picking up a date in a suit and she in a very nice dress. Probably didn't help I was early.
Did I mention her mom liked her wine and her dad his beer. Her mom had finished the last sip of her wine and handed me her coat and purse while she put her shoes on. She bent over and gave me and her daughter a look down her dress, she was not shy. My gf said "oh my god mom" and held her mom's top to stop the view.
Her mom just laughed and said "oops" and giggled and told her hubby it was time to go and out they went.
It was only my third date with my new gf and she apologised for what happened. She laughed and said "you saw my mom's tits before you have seen mine!"
I laughed and smiled at her and said "I like that thought and offer." she turned red when she realised what she said.
She slapped me playfully then snuggled up to me for the short drive. She smelled so good and when we got there I just had to kiss her. So we made out in the parking lot and as time went on we allowed more touching. That got to be a routine we did every time we went to a dance.
The dances were fun. I had never really slow danced much but found I really liked it because of the close contact. Even though we were in a crowd and there was no chance for anything intimate it felt like we were naked and playing. After observing many of the other people there, of all ages, I realised how accepted roaming hands were when dancing close. Especially the more the night went on and drinks flowed.
My girlfriend very quickly knew how and where to rub against me and feel me stiffen against her legs. She allowed my hand to wander lower on her back until I felt her panty line and the top of her butt crack that was perfectly acceptable. We critiqued others as they danced. We sat out a couple of dances and had a drink.
That's when I realised people were there to not only have fun, drink and dance but to show-off and be risquΓ©, most did it not just her parents.
Most of the people there were 20 years or older than we were but it was the most openly sensual and sexy thing I had seen, especially for "old people"! It was educational to see, especially some of the people I recognized that I never thought would do any of the things I observed, especially my aunt and uncle who went.
My aunt had a talk with me after that first dance and told me point blank, "whatever you see or do there, there is an unspoken rule to not tell anyone once you leave the hall". Made sense to me.
I think my biggest shock though was her parents. After getting a good view of her mom's tits at the house, even the ride to the dance was more adult, not parent and child situation. Maybe she and her mom were way more open around each other than I thought but I was intrigued.
Both my GF and her mom were not concerned I was there and I saw things I never thought I would see with them together. For example neither was concerned about totally exposed panties when in the car or both removing bras on the way home in front of me, etc. And I loved it! It must have been something they have always done, hiking their dress up to sit comfort ably. I sure wasn't going to complain with the views I got and I know both were very aware of what was showing!
