34, back in Feb 2005, but orally. In a Sex Shop video booth just up from Macy's in New York, back in 2004. It's probably long gone, along with the shop upstairs which did a nice line in extreme CP videos.
Was flicking through various channels, feeling horny, cock out. It was around 11am, so didn't expect many people to be using these services, but the cabin next door had someone enter, and soon an expectant cock appeared at the two inch high slot.
At first I wasn't sure what I would do, more focused on finding something good to wank to, but it did look attractive, uncut, with a big head. A thought crossed my mind, and in a second I was on my knees in front of it, touching it, before tentatively kissing it, then taking it whole in my mouth, feeling it stiffen a little more inside there.
I had my fingers gripping the slot, on either side to pull me closer to it, running my tongue around the head, sucking hard, the occasional touch of teeth on the glans. His fingers locked with mine, and I could feel him move his hips backwards and forwards. He made no sounds, so I had no feedback other than the movement.
I was thinking how long would this be, when suddenly my mouth was filled with him pumping his load into it. I took it all, despite being a little surprised at first, but soon he softened in my mouth and withdrew, leaving me a little shocked, somewhat afraid, but massively turned on, as that was my first taste of cum other than my own, and I wanted more.
