As your cousin had said, She took you to your aunt and didn't tell her anything about what you had been through or even the fact that it was you. She instead lied to her mom and got you into so much trouble with your aunt. Your now angry aunt was going to punish you like one of her tiny slaves, having no idea its you. Remembering from last time, speaking up or not following orders only got your aunt more mad.
All you could do is hope that she wouldn't be to harsh on you or that your cousin would end this sick prank and save you before your aunt tortures you with her feet.
