Like Seeing Guys Wearing Panties

I was 14 when I caught my friends brother who was 16 wearing his sisters panties. Her and I were watching a movie and I had to pee. So on my way to the bathroom I had to walk by her brothers room. I walked by and thought I saw someone in panties. I backed up and then I saw him looking in his mirror at himself with her panties on and a big boner. I watched him rub it until he shot all over in them. I was so horny that I could not think the rest of the night. Later the next night I said to him I saw what you did last night with panties. He said did you like what you saw? I said yes I would not mind seeing that again. That night I gave him my panties and watched him slide into them. I got to jack him off while he was wearing my panties for my first hand job.
