My wife thinks she's super kinky. She really isn't, but compared to her sister and close friends, she's completely kinky, ha!
Anyway, I often have her imagine ex b/f's while we are doing it--even say their names out loud. She loves this.
She usually doesn't wear panties under her skirts in the summer; making sure to get out of the car as un-ladylike as possible (but often chickens out).
She goes braless all summer, until she has to go outside, then she chickens out.
We love to do it while we are fighting--there is something special to that.
Oh, I did get her to change into pajamas in front of an open bedroom window at night when the neighbor and his friend were outside in the yard. I was looking at them through another window with the lights off and I know they stared at her, but I told her they didn't even look. That was like 10 years ago; I forgot about that.
She nursed our second kid in front of my sister's husband as much as possible, making sure to expose everything--but that is sorta different--although to compare, she never, ever let anyone else see her nursing on purpose (just on accident--but she let my sister's husband see on purpose all the time).
But like I said, in her eyes she is super duper kinky! Ha!
