(This is a true story...)
I had a torrid affair early on in my marriage. with a beautiful girl who was honestly out of my league. She had amazing lips and perfect breasts (only Yulia Nova could top hers). She was unhappily married. I made her laugh – I think that caught her off guard. We fucked whenever we could for the better part of a year - usually in a semi-deserted mall parking lot.
Eventually she returned to her marriage. I was sad knowing I'd never do as well as her again, though lord knows I tried. I was left with memories of her perfect form...and the lingering fantasy she had of me being with another guy.
After several disappointing women, I met Jim online. He was married, about 10 years older. He was very cool, listened to me bitch about women, and gradually earned my trust. He wasn't the typical desperate curious guy who cared only about my stats. We shared the frustrations of married life and our fantasies – I told of him my the fantasy of being with another man. He also told me of a fantasy he had – aggressively taking a younger man. I told him I never knew if I could actually do it. He very graphically told me about wanting to control a younger man, strip off his clothes, and force himself anally on a tight, younger ass.
The idea appealed to me, but I was concerned about having a cock inside of me. Jim assured me he was only about 5" fully erect, so that seemed like a perfect fit. He also didn't want to do anything to please me, which was fine with me. With women, I was always the dominant one, the aggressor. For some reason, the idea of pleasing a man, of taking the more submissive "female" role turned me on.
