You ever think about how nasty and freaky a very conservative woman might be in private?

Women - Wives that seem shy, conservative, quiet, polite, classy...definitely NOT the slut type.
Ever wonder what they might be like in the bedroom ?
We are late 50s, we're not swingers. We do get with a guy friend pretty regularly for sexy fun. You'd never in a million years think my polite wife turns into a sexy as hell woman that can't seem to get fucked enough. None of our friends know we do this.
Years ago I was seeing/fucking a happily married older 41yo gal. I was 22. She was the manager at my credit union. She was very good looking, well dressed, classy and polite. She'd stop at my place almost every Thursday after work. She'd fuck the hell out of me, we'd go three rounds. Hubby had no idea.
I've known about women, my wife's friends that got caught having affairs. I would have never expected any of these women doing this.
...Do you ever wonder about a couples sex life? If they're into adding another woman, man, bbc...whatever.
...Husband or the wife having a hot side peice?
...Have you ever discovered anything like this with anyone you knew ?
If our friends found out what we enjoy they'd be either discussed or really excited.
A female friend once commented about mine and my wife sex life saying it must be boring because she couldn't imagine my quite Muslim wife would be a tiger on bed. I think sometimes when friends look at us they see a dead, boring bedroom life. Only if they knew lol
 
Still water runs deep. My wife and I were married years before I knew what she really liked and wanted.
When of our female friend told me that "even park cars get hit" this was after I tried to get her and my friend together. She was say, even though she didn't have a man at the time she was getting her back blown out my someone we in the group of friend didn't know about.
