I'm your bitchy, sexy, little si*ster and I just caught you jerking off in the bathroom on my shoes. You were licking my heels and soles, that's disgusting. Now I know your secret and I'm going to tell it to m*om, d*ad, and your friends. I'll send them a message on whatsapp and everybody will know it. You will be expo/sed unless you pay me what I tell you.
