The stories are short, not the teens. LOL.
At school lunch one day I sat with a younger kid, Fletch, age 12 who I didn't know well. I was 13. Somehow he got to telling me about the jacking off fun he'd had with boys at his previous school. I didn't tell him much about what I'd done with boys because listening to him was getting me so horny. I asked him if he'd like to go hiking Saturday morning. Yes, he would.
About an hour into the hiking we took a break. Out of the blue, Fletch said, 'When are we going to jack off?'. Wow, what a horny kid. I didn't answer except by pulling down my shorts (no underwear which feels so good when hiking). He, of course, did the same. We laid down under a near-by bridge and reached for each other's dicks. It was always a treat to jack off a younger boy. He was so good to my dick, and I came in about a minute. Then I concentrated on his lovely five inches. He went sort of wild when he came. No wonder he was so active.
Story Two: When I was 14 I went swimming at a pond with a neighbor kid Bill, also 14, who I didn't know well. We were laying on the beach when he started rubbing the front of his swimsuit, and said, 'I'm so horny! I can't get rid of this hard-on.' I told him I had the same problem. He'd given me an eager hard-on. Without saying a word, I led Bill behind some huge bolders. There was a small grassy area. We laid down. Still no talking, we dropped our suits, and reached for each other's hard-ons and began jacking away. Being young, we shot our loads in about two minutes. (I wish we had taken our time and played with each other's dicks for a while before jacking off). With cum on our stomachs, we pulled up our suits and jumped into the pond. I had Bill over lots of times to sleep in my back yard tent.
I notice when writing about my early experiences that about 90% of the time the other boy and I jack each other off at the same time rather than taking turns. A poll on the two systems would be interesting, don't you think?
