My brother and I, Steve, were frequently left alone on Friday nights while our parents went out with friends. One Friday night in particular I told Steve I would be home from a ballgame about 10. Well, the game was cancelled due to weather so I came home early.
As I came in the front door, I saw my brother run from the kitchen into his room. This would have been no big deal usually, but this time he was naked! This turned me on a lot, but I didn't want to make him feel uncomfortable so I just sat on the couch in the living room to watch TV. After a few minutes, the phone rang and it was my parents. Mom said she and Dad were going to stay the night at friends and would be in tomorrow.
Steve came out of his room wearing a t-shirt and shorts. I told him Mom and Dad wouldn't be home, so we were alone for the night. He said OK and sat on the other end of the couch. I told Steve I would get us some cokes if he would find a movie to watch. I went to the kitchen thinking of the vision of Steve streaking across the kitchen totally naked. I became extremely horny and came up with an idea. I opened the cokes, took off all my clothes, and walked back into the living room.
Steve looked up as I entered the room and I could tell he was shocked to see his brother naked. I told him that I had seen him earlier and he immediately began pleading with me not to tell. I said no problem and told him it was OK with me if he wanted to get undressed too.
A few seconds later, he stood up and undressed. Steve was completely naked now and obviously had a hard-on. I in turn got hard and he tried to hide it but I said, 'Let me see. You've seen mine.' He turned around and I told him to come closer. I was on the edge of the couch and he stood in front of me, his hard cock inches from my face.
I had been jacking off for a while and wanted to see him jack off. Something came over me and I just reached out and started jacking Steve's cock. He closed his eyes as I stroked him and in a matter of minutes, he shot off all over my chest and stomach. He stood there panting from cumming and just looked down and said, 'That felt great!'
I immediately started jacking off and stared at his cock as I came on the floor. We cleaned up and about an hour later, we jacked each other til we came on each other's stomachs.
We still jack off together when ever we can.
