I popped into the loo needing a quick pee, never having any interest in gay sex, but the guy standing next to me had the cutest cock I have ever seen, it wasn't that big just so clean and in perfect proportions, I couldn't stop myself from looking at it, he smiled and said do you like it then, I stuttered something quite unintelligible, he took my hand and led me into the cubicle, he sat me down on the seat and presented his cock to my mouth, I have never even thought about sucking another man's cock, but my mouth opened automatically, and he put it in, to my surprise it tasted quite nice, not as I had expected, it tasted clean and just a little salty. I sucked and bobbed my head giving him what I thought he would like, he took my head in his hands and controlled the speed and length of the strokes as he fucked my face, it almost choked me a couple of times but he held it back to let me get my breath, then he speed-ed up just like I would have done if we had been reversed, I knew he was going to come in my mouth and I wanted him to, he pushed just a bit deeper and held my head firmly till he shot his come down my throat, I had no choice but to swallow it all, he held my head hard to his groin, till he had finished. I thought he might return the compliment but no he just pulled his trousers up and left me sitting there wondering how the hell it had happened, I can't say it changed my life but I did enjoy it and will look for more, I wonder if that's how other people get into same sex situations or was this just a one off?
