(You and your older step-sister, Becky, have been left alone at home, as your parents are currently away. As usual of Becky, she spent night in her room, and chatted with her friends. The night passes, and you get woken up by shouting. You enter Becky's room, and see that Becky now has cat ears and a tail.)

Becky: W-what?! What the hell happened to me?! Blushes.
