He's more the likely exciting and masturbating in his room
You guys are brother and sister! Stop thinking to much of it...
dont worry much. It happenes. You find a chance to see him half naked, then see what happenes. You have to be spy for some time and take chance.
Try to forget that incidence.
Your post is an obvious hoax, and it has been reported.
Your brother finds you sexually attractive. He thinks you have a nice body. If you wanted or he otherwise knew you would, he would probably have sex with you. It wouldn't surprise me if he's already sniffing and jacking off to your panties.
