When we were younger me and my best friend started playing with each others cocks. He initiated the first time. We were in the woods behind our neighborhood and he exposed himself to me and started jacking himself. He encouraged me to join him and I did. He got close to me and pulled me close to him and started touching his dick to mine. Then he started jerking me and put my hand on his and said lets do it to each other. We jerked each other until we cum. He told me after. "Don't tell anybody ok". I of course didn't tell anyone.
We started doing this a lot. almost every day. Then after a few weeks we were in our regular spot. We now would both get totally naked when we were doing it. He put his hand on my shoulder and pushed me down on my knees in front of him "You suck me and I will suck you" He said. I looked up at him not knowing what to do. He started rubbing his dick on my face and on my lips. " it's ok, it's just our secret". I opened my mouth and he put it in. He grabbed my head and worked it up and down on his cock. He said "do it like that". I started doing it for him and I could tell he was really liking it. Then with no warning he flooded my mouth with warm thick cum. I pulled off of him and spit it out. He said "man that felt so good, let me do it to you now". He stood me up and started sucking me. It was the most incredible feeling. I did not last long and I cum in his mouth. He kept sucking me until I could not take it anymore. He never spit out my cum.
He stood up and said "Don't worry, this is our secret, never tell anyone ok". I nodded yes and we got dressed and headed back. On our way out he said. "Next time don't spit it out". We both laughed.
We did that to each other for years. All the way through high school. We even both had girlfriends and lived normal lives but never stopped doing that to each other.
