My first time I was 17 or 18. Back then in the early 90s, all along Yonge St in Toronto, on nearly every block from the Eaton Centre to Bloor, there was an adult shop. These shops usually had a couple of backrooms with a small tv set up playing porn, and a few dozen chairs for viewing and stroking. I first found these places when I was 16, and got my first bj's by some older strangers.
One day I found a new place that had several rooms set up in the back, while a clerk sold video tapes out front. The back area was curtained off, and lit only by the porn on the different screens. I paid my fee to the clerk, and wandered from room to worm, taking in the scene. Two areas had gay porn, and one was showing straight stuff. Only two guys were back there, and both soon left. I sat watching the straight video by myself, cock out and stroking hard. I loved waiting for someone to walk in on me like that - was a total rush!
Well, my wish was fulfilled. The door opened and the clerk walked in. He was naked, and had a huge pulsing cock bobbing in front of him. He looked right at me through his steel rimmed glasses and walked towards me, cock first. I was still stroking my own cock, and I stared and his pulsing knob as it came right up into my face. There was a drop of pre-cum on the head that reflected the light from the videoscreen. He reached out and grabbed the back of my head where I was seated in front of him, and pulled me closer until that drop broke against my closed lips. He wanted me to suck him!
I panicked a little and started to tell him I didn't do blowjobs, only handjobs. When I parted my lips to speak he immediately thrust deep into my mouth, slamming the head of his cock against the back of my throat, and held me there! I gagged and made garbled attempts to communicate my distress but he ignored me; just sat there with his cock rigid against my tonsils. Desperately, I sucked air in through my nose before I began to suffocate. As soon as I did, the clerk began thrusting in and out of my mouth, my head still held still and helpless in his hands. Slow and steady, he fucked my face, deep-throating my virgin mouth over and over again. My lips felt huge and swollen and chafed. His cock throbbed and slid along my tongue, and my jaw began to ache from the repeated ab*se!
When the clerk came, he gave no warning. His thrusting stopped suddenly, and I could feel his swollen head resting in the middle of my tongue. He held both me and himself rigid as his cum flooded my mouth! It kept spurting and spurting, hot and salty, filling my mouth, choking me until I swallowed reflexively. I admit I swooned a little at that moment, drinking the cum from this stranger's cock, instinctively gulping down the thick fluid like a lamb at it's mother's teat.
A moment later, he pulled his cock free of my mouth, still dribbling a slow flow of semen from the tip. He stepped forward and crushed his semi-hard cock into my face, smearing the last remnants of his orgasm across my nose and cheeks. Then he turned and walked out of the room, still naked. I looked down in my lap, my cock soft now and covered in my own cum. I had orgasmed without touching myself, or really even being aware it was happening.
I cleaned myself up, and left the back rooms. I tried to exit the store itself, but the clerk had locked the door. He had wanted to have uninterrupted time with me. He unlocked the door to let me out.
I told him, "I don't suck cock.'
He smiled and said, "Now you do."
I left.
I came back a week later.
