Boyfriend's Brother

I've lived with my boyfriend for years and sometimes his younger brother visits us for a few days. He is twenty and way cute. Last time he was here, I stayed up late drinking with him. My boyfriend went to bed, and then the brother fell asleep. He hadn't been wearing a shirt and seeing him asleep and shirtless got me crazy hot. So, I stood next to him staring at his body and pleasuring myself. I was going to stop after a minute, but I got so hot I couldn't stop. I made a mess right on his chest. I got a towel and cleaned him up, but he kept sleeping and didn't know what had happened.
