This happened last year.
Hi I'm Kate, aged fifteen, and this happened last year when I was fourteen. My brother Deejay was eighteen and he played basketball. He's 5'11', tan and has a tight bod. He's really cool and all the girls have a crush on him, even my friends! I must admit..he's a looker. Well one day I came home late from my friends birthday party and I was really tired. As I was getting ready to go to bed I noticed a light coming from my brother's room. I ignored it and went to the bathroom. When I came out, the light was still on and I started hearing noises. I wonder what's going on? I thought. I peeked through the crack of the door. My brother was lying on the bed with his hand shoved in the leg opening of his boxers! He was stroking inside his white boxers and he started to moan.
He took off his hand and started stroking his butt for a while. Then he put his hand on the front of his boxers and was holding his dick through the fabric. I could see the outline of his hard-on which got me really excited!!! He put his hand on his waistband and pulled down his boxers and I saw his dick!!! It was very long and I could tell he was cut. His balls hung low and with one hand he was massaging his balls and the other hand he was massaging his dick. I lay there mesmerised at the sight! His dick was so long and thick!!! He didn't have much hair above his dick though. It was just a small patch of black hair. He kept moving his hands from his balls and teasing his nipples. By now I was getting really wet. It felt like hours until my brother crunched his abs together and streams and streams of cum shot to his stomach, face and the wall!!!! He grabbed his boxers and cleaned himself up and turned off the light. I quickly ran to my room and fingered myself through the whole night. This still gets me off!!!
P.S. My brother is coming home from college in a couple of weeks and is staying in his old room. Hopefully I'll see more of a show. If I do...I'll let you know.
