I started jerking off at younger age. Learned from a friend during a truth or dare game. Went home that night and tried what I had learned. Did this everyday from then on.
I shared my room with my younger brother. I would jerk off when I thought he was asleep. I recall one night my brother complaining about the bed shaking. I told him I was doing what our friend showed us. He said cool and started doing it too.
I had heard that women use vibrators. My parents had a massager that plugged in to the wall. I snuck it out of there room one day and stashed it in my room. That night I told my brother what I had. He said let's take turns using it. We got naked and laid on the floor. I went first. I turned on the massager and pressed it against my penis, which was already hard in anticipation. It felt so good. We decided to go for ten minutes then switch over. I was nearly ready to blow my load when my brother said it was his turn. I handed him the device and he proceeded to lay it on his very hard member. We never touched each other or anything like that. It was just two guys making themselves feel real good.
We went back and forth with the massager several times before we could not take any more. I was the first to cum and boy did I come. I think some hit the floor behind my head. My brother came pretty quick after I did and just as much too. We did this several more times over the years. Never anything sexual between us.
