When I was 13 I learned how to masturbate. I shared a room with my older brother and he taught me how, not through showing me, just by telling me. I did catch him jacking off once though, but that's not the story. One day when I was 14 I was home alone with my 13 year old brother. It was summer. We played video games, watched movies and then decided to go swimming. We went into our backyard with out swimsuits on and jumped in. I am a competitive swimmer and have bikini briefs for my swimteam; I also have regular swim suits that are like shorts but that day I wore my speedo. We swam laps, threw a football, and then went into the hot tub. I caught my brother staring at my crotch.
It was a hot summer day, and the hot tub made it worse. I complained about the heat. 'How can you be hot in that little speedo? your junk is practically hanging out.' He commented. 'Yeah I guess.' I said laughing. 'I bet that's more comfortable.' He said. 'Yeah I guess.' I said again. 'Can I borrow one?' He asked. 'Sure.' I said. He made a comment that it would have to be next time because he couldn't go in and get it now he'd get the floor in the house wet. 'You can try it now. We'll switch.' I said. I took of my speedo, letting my dick fall out and hit the warm water.
He stared at it for a minute.'How big is it?' He asked. I said I didn't know. He looked at me and smiled. '6 and a half inches hard.' I said. He removed his swimming shorts and handed them to me. His dick was pretty big, and on its way getting hard. He slipped on the briefs but found himself having a problem. 'My dick can't get in.' He complained. 'It's cause your hard.' I laughed. 'You have to wait.' 'There's only one way I can get rid of a boner.' He said. 'Me too.' I replied, taking off the swim shorts he had just given me.
We both proceeded to jerk off. I was having the time of my life. I held my balls underneath the bubbling jets. 'Does that feel good?' He asked. 'Fuck yeah' I replied. He tried it next. I stopped and watched him. His hand was going up and down his shaft (which I later found out was around 4.5 inches- but that's another story)and he flung his huge ball sack around. He moaned and cum shot out of his little dick.
Then it was my turn. I started jacking my cock furiously, and even added my other hand to my shaft. I rammed my ass against one of the water jets and felt the warm water up my asshole. I was in ecstasy as I came.
