I started letting one of my buddys fuck me about half way through our senior year in high school, it's now over 5 years later, he still does, and was the only one untill about 6 months ago. Where me and my buddy work there's this humoungus fat dude, he's a snitch, always running to the forman telling on anybody he see's bending the rules. We started calling him fat albert, asking him when was the last time you saw your dick, stuff like that, I think I was the worst one to pester him. I don't know how he found out about me and my buddy keith, but one sunday afternoon he came over. I invited him in asking whats up, he said I know you let keith fuck you anytime he wants to, and today I want to, and if you don't let me, I'm going to tell him that you asked me to, and I did. I didn't want that fat fuck screwing me, but then he said, and I'll tell the boss that I saw you and keith fucking in the restroom. I said ok you fat cocksucker I'll let you, all I had in mind was to tease him till he got off, then run his fat ass out. He's over 6ft and we guessed his weight at around 400lbs, I'm 5-8 and tip the scales at 170. I got undressed, he did the same, good grief, I never saw so much fat. Then he got a hard on, it was hugh to, and he wanted me to suck it, I refused, saying you wanted to fuck me, thats all you're going to get. With that I walked into the bathroom and came out with a tube of ky jelly, slapped some on his dick, turned around, put some on my ass, and got down on all fours. I was thinking he's so big he'll never be able to get anything done. He got completly over me, one hand on either side, his huge belly drapped over me like a blanket. Almost instantly he started poking, trying to get it in, he was too tall and was stabbing my tail bone, then over my back. I figured he'd tire out in a few minutes so I stayed with my knees togather and let him go at it. It was embarrassing but I'd agreed to it, I looked up and our image was real clear on the screen of the tv, he looked like a draft horse stud trying to breed a pony. The thought struck me as funny, but then something happened, my thoughts of teasing him changed to wanting him. He was still trying, so I relaxed and started helping him, and in a few seconds that big old draft horse was no longer trying to breed that pony, he was doing it. As soon as he got in he buried it hard, and never stopped, he was big and it hurt for a short time, then I leaned back and let him go. He lasted, and when he did get done I was soaked with his sweat, my legs and arms were shaking from holding his weight, he was breathing like a race horse. After a few minutes he got his breath and said, I saw you look at that tv screen a few times while I was fucking you, which was true, and I saw him looking too, each time he had a slight smile on his face. Then he said, tomorrow when we're at work and you call me fat albert and saying hatefull things about me to your friends, just remember what you saw in that screen, and remember also that the cum in your ass came from fat albert, not your buddy keith. That sorta put me in my place, because I had said ok you fat cocksucker do it. Later that evining keith came over, he was laughing when he walked in, I asked what's so funny, he said I ran into fat albert on the way over, he said that I needn't bother going over he had already been there and fucked you for me. I said I dought if that fat fuck can jack off, much less fuck anything, keith said well that's what I came over to do, and headed for the bedroom. I let him as I always do, but the whole time I was thinking about fat albert, and to this day no matter how much I say I can't stand the fat fuck, I can't get that picture out of my mind, and the fact that I let him fuck me and liked it.
