I was only about 18 or so at the time, but I was insatiably curious. I'd found my dad's stash of porn months before and was regularly fingering myself to climax after climax while reading the stories. More than a few of them mentioned "adult book stores" and "glory holes" and I found the idea so very erotic. Imagine having cock after nameless cock at my disposal to suck off at my leisure. Incredibly horny men who wanted it so much they would just offer themselves to whoever was in the next room. The anonymity was almost as much of a turn on as the sluttiness, itself.
I gathered my courage up and made my way downtown to a seedy-looking establishment with quite a few disreputable characters inside it. Being an attractive young girl, I got more than my fair share of attention as I wandered around the store, looking at the magazines, the lingerie, and eventually the dildos. One of the store clerks, a mildly attractive guy in his mid-20's came over and tried not to be too obvious about staring at my chest as he asked if I needed any help.
I blushed bright red at the thought that immediately popped into my head of asking if I could suck him off. Of course if I asked, he'd no doubt have said yes, but there was no way I was going to be able to ask that. Instead I asked about quality and comparisons of the various dildos on display. He immediately launched into a sales pitch, praising the virtues of each of the models in turn. I nodded vaguely and glanced around me at the men in the store who all seemed to be angling for a good look back at me. All of the attention had my imagination running wild and I guess i seemed a bit flushed because the salesman grinned and asked if I wanted to try one out.
I was a bit surprised at that, and blushed even redder, but I took a deep breath and said "sure, why not?" and he raised an eyebrow, reappraising me, before handing me one of the smaller models and directing me to one of the movie rooms in the back. He even gave me a few quarters for the tv.
I settled down to watch the cheesy movie that flickered across the screen, and it wasn't long before I saw something out of the corner of my eye. There was a cock sticking through a glory hole in the wall, and it was dripping a bit of precum, already. I gathered up my courage and moved over to the wall, kneeling down a bit apprehensively before hesitantly taking the cock into my mouth.
As soon as it passed through my lips, I closed my eyes and sighed in satisfaction. This is what I wanted: to be on my knees sucking a nice hard cock down my throat. I moaned quietly and heard him moan in response and the cock started to move back and forth, fucking my eager young mouth. I licked the shaft all over as I sucked on him, wishing I could feel his hands on my head and see the expressions of ecstasy.
