When I was in the army, I knew a guy who had a big dick. He was Italian, and from New York, I was from Wisconsin. One time we were doing some training at night. We were in defensive positions and had made foxholes. It was cold that night, and I had wrapped myself in a poncho liner. He said that we should spoon and wrap ourselves together in the liner. We joked about this for awhile, before i said ok. He was bigger than me, and I had seen his penis before. I knew it was large. I hadn't been thinking about this, but It would come up later. He wrapped the poncho liner around himself, then while we were both standing, wrapped his arms around me. I was facing out of the covered foxhole, watching for the simulated opfor, and he was pushing into me. He rested his head on my neck, and i joked about, "what are you doing??" He said just relax, and I could feel his breathe on my neck. My dick was being pushed into the side of the foxhole, and was getting quite hard. I was pushing my butt out and he was pushing me back. I could feel his dick getting hard. Don't know why, but i started to grind into him, and he responded back. After awhile, and without words, i set my rifle down and started to rub him through his BDU's. His dick was quite large. After only a short while, he undid his pants and pulled them down to his ankles. He then pushed me back into the wall and grind-ed against me sliding his dick in between my legs and rubbing on my pants. He then reached forward and undid my pants and pushed them down to my ankles. He then placed his dick aimed right at my hole and humped me. I could feel the coolness of his precum and it was getting quite slick back there. As he humped on my hole, I began to push back, and ever so slowly his dick started to penetrate me. I was shaking and quivering as he held me around my neck and waist. His cock was so large but he was very good at seducing me. I felt like a telephone pole was up my ass. He was telling me how tight my ass was, and how he knew i wanted it. His pace quickened, and his balls slapped on my ass before I knew it he was cumming in my ass. After awhile, he slid out and leaned against the wall. I turned around and could see his extremeness. For some reason, he reached out for my neck and pulled my head to his cock. He whispered "suck it", which made me so hot, I dropped to my knees and began to blow him. He told me what to do, smacked my face with his cock when my teeth grazed him. I couldn't believe how feminine I felt as his erection increased again. It wasn't long before he shot his load into my mouth. After it was done we dressed up and never talked about it, but I could see him looking at me from time to time, while I looked at his crotch. I was transferred soon after, but I have never forgot that time.
