SHOCK! HOW DID I NOT NOTICE THAT?!?

Last week my sis and her boyfriend came to visit me, which I honestly thought was pretty cool, because I just always find her old one pretty hot! As I was getting ready in the bath, I suddenly heard something....Hää was geht denn ab?!? The little peeping tom is standing there and getting horny on my nude body! :D If he's already so curious with his young horny cock and girls looking at the tits, then I want to see how much guts is in the young balls so and whether the peeping tom is also a fuck. Do I tell my sister? It depends on whether the cock can be used again! :D
