I've never shared this story with DL despite being a frequent poster, because I thought it wouldn't be believed. But, about a decade ago, when I was in my late 20s, I went out bar-hopping with a couple friends and was designated driver. They all got fucked up and it was a time-consuming drag to get them all home - the last guy was extremely intoxicated, and lived in an obscure part of our city that I was not very familiar with - lots of old warehouses and railroad tracks. His directions were terrible, we drove around in circles forever until we FINALLY found his building. He stumbled inside and I realized I had little idea how to get back to an arterial street. By this time it's almost 3 a.m.
Somehow - I'm still not sure how it happened - I got my junky old car marooned on a small, muddy berm right next to a railroad track. There weren't any trains around, and I wasn't ON the track - just next to it - but it was still sort of terrifying. I got out my cell phone and called Triple-A, which dispatched a two truck driver to come help me. He was about the same age as me, average looking working class white guy.
The positioning of my car was very weird and it was a real bitch for him to get it out. I was physically and emotionally exhausted at this point.
He towed me back to my apartment - the car had stalled out by now - and when we got there, the sun was starting to come up. I paid him, then, I asked him if I could make him a cup of coffee and he said sure. We went in my apartment and he immediately plopped on the living room couch, without me even inviting him. Despite coming down from near-hysteria - or maybe because of it - my cock started to bob.
I made the coffee, filled two mugs and went and sat beside him. He immediately started to rub his crotch. I joined in, and within minutes he pulled out a really nice hard cock with a thick, dirty blond bush. I stroked it for a while, then made to go down on it but he stopped me - "No, don't. I'm straight." So I kept working it with my hand until he blew a nice, sticky load all over his shirt.
My cock was straining in my pants, so I said, "You mind if I get myself off? You don't have to touch." He said sure so I whipped it out, and shot my own load in about 15 seconds. I grabbed a roll of paper towels, we both wiped off, and he said, "I gotta go." I thanked him again for his help, and he left.
