My 1st wife was a young, wild thing. We were very young (me 18 she 17) and had dated some during high school.
I thought we were pretty much a typical young couple for the first 6 months or so. After that, it was like a switch had flipped, and all of a sudden, she couldn't get enough dick or pussy.
We got to a point to where we were inviting others over for play time, and would swap in separate bedrooms.
She wanted to fuck a friend/coworker of mine who we had partied with before, but they didn't have any chemistry. She invited him over one night, specifically for that purpose. My reward was getting to fuck a (female) live-in roommate of ours.
After it was over, and he left to go home, we reunited in our bedroom, and she was filling me in on some details. She happened to mention that his dick was "much bigger than I remember", and it was an instant adrenaline rush! Just those few words said so much!
Maybe a month or two later, that same feeling came over me when she asked permission to fuck one of HER coworkers!
When I met my current wife and we began dating regularly, she had a coworker half her age sniffing around, trying to get her to give up her pussy.
We were in bed fucking one night, and she said that he had finally asked her, that he wanted her to teach him about sex and how to perform at his best.
As we were discussing it, I asked her what did she want want to do; did she want to fuck him?
She said, "oh, yes, I want to sit on his dick!"
I had a familiar feeling some 20 years later. Again, just a few words said so much, and I remain excited about their times together to this day!
