Guy's would u wear a dress at 10 year's old

I been talking to my sister on the phone this morning. They went to some friend wedding last night. Well as a joke my brother he is 10 and they got him to wear a dress and he put a pillow in the dress to give him a big booty. Omg they went to town for something and they went to the store. The owner notice my brother wearing a dress and he turned around and bounced his big booty for the man and he loved it. This older man walked in and seen what was going on he commented about his booty also. My brother ended up being a flower boy for the wedding.
