When I was 18 and my baby brother was 18 something happened that I haven't forgot in 4 years! I came home from college on a Friday morning knowing that my parents were working and my brother was at school. When I went upstairs to my bedroom I noticed my parents door was closed but ajar, usually it is wide open when they're not home. I walked barefoot over to the door and peeked in to be totally shocked! My brother Mark was lying on top of my parents bed totally nude and talking on the phone. I watched for what seemed like hours but was only a couple minutes as he began to rub his semi hard cock and his huge balls while still talking on the phone. As his cock grew harder and bigger he gripped it tighter and began pumping his right hand up and down stroking himself real slowly. In the midst of him stroking himself he abruptly ended the phone conversation and hung up the phone. That's when the fun started, I continued peeking in watching him ever so slowly make love to his own body, stroking his huge cock and rubbing his nipples with his left hand. Just as he was starting to go at it with faster motion my cell phone rang and startled both of us! He jumped off the bed with his huge cock now pointing upwards and called out my name "Jamie your home already"? With that I opened the door all the way and asked what he was doing. He told me he was on the phone with his girlfriend and she was telling him about how their sex went on the previous Saturday and he was getting "turned on"! He asked if I had ever seen a guy "jerk off", in which I did and did I ever see a cock as big as his.
