I stroked his shaft as I suckled on his head and it slurped in and out of my mouth. I moved my left hand down into his pants, and gently cupped and fondled his balls. They felt huge and I wanted to see them. I tried to pull them from his pants but they wouldn't come out. He reached down and adjusted his pants and I was able to free them from their confinement. As I was no longer stroking him, I wanted to try and take his entire length into my mouth. I released his balls and held the base of this cock firmly. Then I worked his thick rod in slowly, little by little. I couldn't get the entire length in without starting to gag a little, and ended probably two inches short. He made the first noise I heard from him as he let out a long, low moan.
He had stopped stroking my cock by then and that was fine; I wanted to give him all the attention and pleasure without me or him being distracted by him playing with me. But I took up jerking myself with my left hand as my right hand started up and down his shaft again. This time, I was moving my mouth up and down as well, matching the pumping of my fist. His rod was now really slick from my saliva and I found I could easily travel his entire length with every stroke and pump into my mouth. I felt his hand on the back of my head and he was really getting into it, as was I.
After a few minutes, I heard him grunting softly with every downward plunge of my mouth on his swollen cock. I released my own cock and put my left hand back on his balls and rubbed them, more firmly this time. I was going to make this experience the best he could have, just for my own satisfaction. (I like to think I gave him the best blowjob of his life.) I felt he had both hands on my head now, pumping me harder down onto his rod. I wanted to take his load in my mouth and swallow every drop.
I felt his balls tighten in my left hand and I squeezed and kneaded them a little more firmly. His head swelled even larger in my mouth. I stopped moving my head up and down and locked my lips around his cock head. I was now pumping hard on his slick shaft with my right hand. I heard him gurgle something unintelligible; I assumed he was letting me know he was going to come. Then, I felt his shaft flex and the first shot of come cover my tongue. It was salty and thick and hot. Immediately, a second shot followed, and then another. I held his come in my mouth for a second, feeling him fill me up. I then swallowed hard and gulped my first mouthful of come down. Another shot came, and another, and another. His orgasm seemed to last for a minute, though I'm sure it was probably only a few seconds.
I felt him going limp in my hand and I sucked out whatever was left in him. I straightened up and he put himself back together. My own cock was aching and I started stroking it. The guy encouraged me, saying quietly, "I wanna see you shoot." It didn't take long before I felt myself starting to come. I pointed my cock away from him and spurted a huge load against the wall. It felt so good and was my first orgasm in front of somebody. A day of firsts.
The guy then unlocked the booth door and left, just like that. It was awesome and I've often wished I could have another experience like it. A few times I've looked through postings on craigslist and found guys local to me who wanted anonymous, oral sex encounters, but I haven't worked up the nerve yet to answer one of the posts. Maybe some day.
