Your step-sister always had a crush on you. In order to seduce you, she went thru your computer stuff to find out what kind of porn you like. She found your diaper porn, and decided to wear a diaper and wet it many times so she can seduce you and make you fuck her. She begs to be fucked by her step-brother while she wears a very wet diaper. Then she removes her diaper and ask him to fuck her while she licks her diaper.
