I hope this happens again!
To start out, I am gay and Justin is straight. Well, when I was about 15 my dad started dating a woman named Melissa. Melissa had 3 children, Justin (15 then), Katie (12 then), and Jaimie (9 then). I never like Justin, although I found him extremely hot! He had a nice smooth, built body, and he walked around in boxers usually, and you could see every little perfect detail in his body. He had short dirty blond hair that he usually kept spiked, and blue eyes. Well, he was always extremely open and didn't care who saw what on him. On many occasions he would flash me his dick. His dick was perfect! It hung on his ball sack, his shaft was nice and tan, he had a mushroom shaped head (which I loved!), and was about 7 inches long.
One night, I was extremely horny and had always wondered what his cock had looked like. It was dark, so everyone was asleep, including him. I carefully walked over to the couch he was sleeping on, and sat there and watched him sleep for I would say 15 minutes. I finally got up the nerve to touch him. I first rubbed my hand on his perfectly built smooth chest, and my hand happened to work down to his thigh. I carefully put my hand under the covers and found his boxers, and touched his warm cock, and I jumped when I touched it. I slowly un-buttoned his boxers, and pulled his soft dick out, and also pulled my dick out to start jacking-off. His dick slowly turned hard as I was stroking my 8-incher, so I slowly started stroking him.
Through-out me stroking him, somewhere, he woke up without me knowing. He pushed my hand away and started stroking me. I jumped back in amazement! His warm hand felt awesome on my throbbing cock, and I quickly knew I was going to cum. We both starting breathing heavily, and I knew he was also getting ready to blow! He pulled his boxers and covers down and had me sit on his thighs. He put his cock on mine, and we jacked them both together. Within 30 seconds we where both blowing our loads on his chest! We sat there for a minute trying to catch our breath. We both got up to clean up, and went back to bed. We never said anything about it again. I really hope this happens again! His cock is so beautiful. Well, I have to go jack-off thinking about him. Happy jacking!
