My friend Trey always had me over to their house. We were close friends, and were really open with each other. I remember when he first told me about jacking off, and I didn't really understand. He said he saw his dad jacking off one night, and went to his room to do the same thing. He felt good, but didn't cum. A couple years later, I was at his house, spending the night, and got up in the middle of the night to use the bathroom. I saw a glow from his Dad's office, and walked by seeing his Dad jacking off. It was exactly like Trey said. I didn't stay to watch him cum, but I remember thinking his dick was huge! I went to the bathroom, and jacked myself off, with a little bit of cum.
Over the next couple of years, when I'd stay at Trey's house, I'd get up at night and see if his Dad's office had the familiar glow. When it did, I'd sneak by and see if he was jacking off. Nine out of ten times he would be. One night I almost got caught, cause his Dad turned to get some tissues off his desk and looked up. I quickly scooted back to the room, and hoped to God he didn't see me. I learned quite a few strokes from his Dad, including pulling on my balls, and even some ass play. He always has a shirt on at least, but you can see his lower half clear as day in the glow from his desk lamp.
Last year was the last time I stayed at Trey's house, since his Dad got a job out of state, and they had to move. I knew it would be my last time there, so I hung out until he fell asleep, then I walked down the hall, and seeing the glow from his Dad's office, I peeked through the glass panels of the office door. Sure enough his Dad was standing there strokin away at his desk. I waited for about 30 minutes, and I watched his Dad cum. He finished by squeezing his big dick at the base, by his balls, and doing quick little strokes up and down on the head of his dick. He shot quite a few times, coating his t-shirt and getting a lot of cum in his curly pubes. I waited to see if he would continue to jack, and he did for a little while. Then he wiped himself off, and got up to pull his boxers up. I walked back down to Trey's room and went to sleep.
The next day I said goodbye, and shook his Dad's hand. He told me it's been a great few years, and hoped he'd taught me a few things, winking at me. I think he knew I'd seen him a few times, but I'm not exactly sure.
