One day when I was in school, the boy sitting next to me was always restless and never sitting still. Personally, he always got on my nerves. Most of the time I didn't pay any attention to him.
I looked over at him and I saw him stick his hand down his pants. He started playing with himself. I was shocked. He did not know anyone was looking at him. So, he pulled out his penis. It wasn't erect and it was a little small. He left it hang out for a while and he touched it. Then he stuck it under his shirt and rubbed the shirt over the head of his penis.
I was soo horny, I was rock hard. Later that day when I got home I masturbated a couple of times while thinking of him touching his penis. I still think about this every time I masturbate.
