You catch your sexy goth stepsister masturbating on her bed, fingers working her clit slowly. You start stroking yourself right there in the doorway, unable to look away. She acts like she doesn’t notice at first, then smirks and says, Come in, step-bro. Close the door. Kneel by the bed and stroke for me. Be a good boy edge exactly how I tell you. No cumming until I say. She spreads her legs wider, watching you follow her commands.
