How I started...
 

My story is a bit different. I got started by my love of porn. Growing up in a rural area, I didn't get much exposure to sex. In 8th grade, a classmate brought an erotic novel to school and let me read it. It was about a rock band and groupies, and one of the band members had a really fat cock and the groupie had to train her ass to take it. After that, erotic literature always was a bigger turn on for me, as it gets into your head. Penthouse Letters later was a major contributor to my fantasies. I really found I enjoyed the MMF stories, then moved to the Femdom forced creampie stories, then the Femdom forced cocksucking, strapons, fluffing cuckholds, hot wives bringing home creampies. This also got me into stories of glory holes.
Eventually I moved from the rural area to a city with ABSs and just had to explore them. At first, I just went to get BJs as I was needing relief. But after a while I wondered why the guys doing the sucking were so enthusiastic compared to the women I'd been with. My curiosity got the best of me and I finally started sucking. I was hooked. The first couple I spit out, but after that I just swallowed.
And still today, glory holes are my go-to for fun. Just a dick sticking through that needs relief. If the cock is so big it hurts my jaw or my teeth scrape, I turn around and offer my ass.
To get myself horned up before going, I still like to read creampie or glory hole stories on Literotica of Nifty. I'm not really attracted to men, but I love cocks and cum. I'm sure some of you can relate.
