I found out your secret big brother... I know you sneak into my room to sniff & steal my dirty socks so you can jack off with them later. I decide to confront you about it, and instead of letting mum know you're a gross pervert I've decided to give you the chance to continue sniffing my socks... so long as you pay me. You can even lick my feet, but it'll cost you a bit more. But it's better than me telling mum, right?
