Had a regular back in the 90's. She was my ATF because first off the price was affordable to me at the time and was able to see her every 2 weeks or so for about 3 years. Now for the next reasons. She was cute. My body type. Great smile. Smelled good. Dressed a bit trashy which was a turn on. Now for the next level reasons. Every few months she would add to the experience by surprising me with new experiences. I didn't ask for any and there was no asking for more money from her but I did throw in a few extra dollars. The first time, out of the blue, after vigorously giving me a CBJ she ripped off the condom and begged me to COF. I had never done it before. To have a fantasy come to life just like that was stunning. Now, I only ever do CBJ, NEVER FS, but I was so comfortable with her that the day she took off the cover to finish me off, I just went with it. The next year I struggled to not go FS despite her repeatedly doing her best to get me to cave. The closest I came was when she told me that "I need you in my ass". OMG that took discipline.
There were other firsts with her. The without warning prostate massage became my all time greatest orgasm. The time that she insisted on showering with me only to realize that her plan was to RIM me. I may have passed out. I totally sub missed to her when unexpectedly she Snowballed me and nearly started to cowgirl. She stopped but not before getting herself off while still Cum kissing. To this day, I have never seen a girl have such an intense orgasm. I didn't know back then about this fetish.
Then a few months later it was all over. She told me one September night that I was her last client and I could do whatever I wanted. I told her that I just wanted to make-out for an hour. We mutually finished each other off. She refused my money and we went off to live our lives. I saw her once about 10 years later at a mall with two toddlers. I kept my distance and she didn't see me. Haven't been to that mall since.
Nothing has come even remotely close to that ATF.
