I share a condo with my brother on our college campus. One day my brother came home in spandex biker shorts. Spandex is tight body-hugging material, so I could see the shape of his private parts (it's a bulge that sticks out). From that day onward, I started to have a secret sexual attraction for him. I had an overwhelming desire to watch my brother masturbate. He's single, so I knew he had to masturbate (all men do, especially single men). We have a security monitor in our condo and we have images of the kitchen, the living room, and the dining room. I reset the security monitor so that I could have an image of my brother's room instead of the living room. Once I did that, it was only a matter of patience because my brother works, goes to the gym, goes out with his friends, etc.. After two weeks of patient waiting and checking the security monitor, my desire was about to come true. It was around 9pm and my brother was about to masturbate. He took off all his clothes and lay on his bed. He read a book for about 10 minutes. Then my brother started touching his body. My heart was racing so fast that I could barely breathe. He spread his legs wide apart in the air (very wide apart). He started to stroke his cock slowly with lubricant. It became so big and erect. I noticed that his cock was slightly bent. The security monitor had no sound, but I knew he was moaning because of the expression on his face. He also rubbed the tip of his cock. When he started shaking and I saw agony on his face, I knew he was approaching orgasm (and he was stroking his cock faster). Then he got his head closer to his cock and then he squirted out his milk. He squirted out a big load of milk. He kept stroking his cock until all his milk was out. I couldn't believe that I had watched my brother masturbate. I couldn't believe that I had watched him milk himself.
