I Saw My Brothers Naked [I Am Naked Right Now]

When I was 17 and my brother was 13 my parents were out of town and I went out with some friends. I was supposed to be out for a while but I came home after we ate. I walked into my room and my brother, Caleb, was at my desk, naked and jacking off to something on my laptop. He stood up and didn't didn't know what to do so he was just frozen there. He penis was about 4 inches fully hard. He was really embarrassed and I started laughing and that just got him even more embarrassed, he ran off to his room. I looked at my laptop to see what he was watching and he was on my Facebook, looking at my friend's and my profiles looking at the bikini pictures of us. I went back to him and told him that is was ok and he's not the first naked guy I've seen. He asked me if his dick was big and I said it was ok but don't worry, it will grow.

I've seen him naked again, but ever since then it hasn't been as weird.
