When I was 19, I spent the holidays at my dad's place on leave from the U.S. Navy after a couple of months at sea. My dad had remarried and his wife had a kid from her first marriage who was in high school. The kid was really just a few years younger than me but at first we didn't seem to have much in common and we stayed clear of each other. My dad and I never had much to do with one another while I was growing up--he and my mom lived on opposite sides of the country--and I had never met his wife before. So I was almost a stranger in the house and on my best behavior.
For a few days I was a good boy. One morning five or six days into my stay, after my dad and his wife had gone to work and the kid had gone to school, I couldn't hold out any longer. I got a paper towel, pulled down my dungarees and spread out on the couch in the rec room, which was where I was sleeping.
It was the first time in a long time I felt like I had the privacy to really enjoy what I was doing. I started out slow and worked up to where I was almost ready to blast off, backed off and then did the same thing a few more times. I was just about ready to take it all the way when I looked up and realized that the kid was standing in the doorway staring at me. Apparently it was the last day of school and he got out early.
There I was, sprawled on the couch, my dungarees around my ankles and my dick clenched in my fist. Right away I let go of myself and went slack. I must have turned deep red.
We just stared at each other for a moment. Then I figured, what the hell. He caught me red-handed and there wasn't anything I could do about it. So I grabbed my dick, gave it a few strokes, grinned at him and said, 'Hey, man, what's the big deal? Don't tell me you never beat your meat.'
He didn't say anything. He just kept staring at me with a funny look in his eye that I couldn't figure out. Finally I said, 'Look buddy, you can see what I'm doing. Now get the fuck out of here.'
He still didn't say anything. He opened his pants and out popped his wood. He let his pants fall to the floor, stepped out of them and sat right down on the couch next to me. I had never jerked off with another guy before and I was surprised how much I enjoyed it. At one point he bent over and tried to take my dick in his mouth, but I said, 'Whoa, that's too queer.' When I came I spurted spooge all over him. I think he loved it but he went up and took a shower afterwards.
Well, we jerked off together several more times before I left and eventually I did let him suck my dick. I was hoping we could get together again the next time I came to visit my dad, but the marriage fell apart and I never saw my young jo buddy again.
