Look at this pair of panties! It belongs to me and Mistress Uzi, we mailed it to you and told you to cum on it and send it back to us. So now you're fucked up: we have your DNA!!! hahaah! We' re gonna find everything about you and tell everyone who you really are. Or we could do even worst things, like spreading your dna on criime scenes and funny things like that :D Unless...
