I grew up in an insanely small town. Population was about 300 in the 1990's. I graduated high school in 97, and lived locally for a long time. I was pretty well out of the closet even in high school, and surprisingly in small-town Nebraska, very few people cared. I was pretty lucky that way. Anyway, our basketball coach was also our history teacher and also assistant football coach as well as assistant director for the plays. Yeah, everyone did double or triple duty. He was in his early 30's, fairly tall. Not unattractive but I never had a huge crush on him or anything. He was kind of a dick though. Everyone felt that way about him. And he even made offhand comments to my face about my sexuality. At the time I was too timid and sheepish, and just denied shit. Now I would have been way more militant. At any rate, my senior year, we had 6 AM basketball practice on Saturdays. That was a fucking drag. And I sucked at basketball anyway, and had no passion for it. I was just there to see boys in the locker room, quite honestly.
For whatever arbitrary reason, he made me run extra laps one day. The other boys already left by the time I was done, and it wasn't too weird-he was fickle and often made someone do more than the others. I didn't know where he was when I was done, so I just headed down to the locker room. He was arbitrarily in the shower. There were only three heads, and he was in the middle, so I had to take one next to him after I got naked. His back had been to me - he had a great ass, actually. And as I got into the communal showers, I saw his dick. Holy fucking shit. It was HUGE. Flopping around, all meaty and just looked weighty. LOL He had big, lowhanging balls too. He at one point asked, "What are you looking at?" and sort of took on the role of a bully, but only mildly and momentarily. I can't stress enough how odd this guy was. Anyway, he finally just stared at me defiantly, and started stroking his cock. It was like he was daring me to either call him out for being a perv or daring me to want it, one or the other. And to be fair, I was 18, so it wasn't illegal, just unprofessional and weird. He had a huge boner, and he just stood there almost leering at me. Like he hated me. I got hard automatically, and after a minute he said something like, "Well? Grab yourfuckingself, son." So I started jacking off.
He began asking me all these weird questions. "Ever have a dick this big up your ass, boy?" I told him I hadn't ever had a dick in my ass, which was actually a lie. I had gotten very lucky two years prior, but hadn't really had anything since. He asked me if I liked sucking cock, and had I sucked a cock that big before? He told me he was 11 inches, and I believe it even now. He continued to leer at me, and faced me. Sort of wagged his dick at me and told me it was huge. I could see that. He wanted some cock worship out of me and I didn't really know how to give it to him at that age. He wanted me to describe it, so I told him it was big, and it looked heavy. He kept saying shit like, "That's right, I have a huge dick, don't I?" And wanting me to agree. I finally came; I was trying to slow up and hold off a little. LOL He sneered when I came, but like proud of himself. Minutes later, he jizzed everywhere without any warning whatsoever, and yes since he was facing me, a lot of his load hit me. We finished our showers silently, and after we dried off, he sort of backed me against the wall. His dick was against me, he was so close. He literally said, "Everyone knows you're gay so nobody will believe you." As like, a warning for me not to tell. I mean, looking back it was horrifically wrong for him to behave that way. Although, I don't really care. I was of age, and I got to see his big dick shoot off. There was no other incident with him, nothing. It was just really fucking bizarre.
