When I was fourteen years old I was a ball of out of control hormones. Some guy probably 50 years old came to work on our furnace and heating system. He was there on and off for about three or four days. I followed him around and bugged him because I liked the attention. We were alone most of the time. I kissed him a few times and was very flirty, sticking out my chest and touching him constantly. On the second day when I saw him laying there with his head and chest out of view and just his bottom half sticking out of the area behind our furnace without saying a word I started feeling his cock which got nice and hard. He didn't say anything so I unzipped him and pulled it out. It was the first real one I saw and it looked huge to me. I sucked on it awhile then lined it up with my hole and just slid right down on it. It didn't really hurt like I had always heard. It was a bit uncomfortable at first then it just felt good. I slid up and down on him til he came then I just ran out of the room with his cum running down my legs. The next day I did it again.
