You give your stepsister a magic potion. You tell her is a special tea. She consumes it and becomes more and more bimbo! Everyday she gets more bold, even dirty talking and rubbing outside your pants. As the days go by, she surprises you at night with her masturbating with a vibrator, getting naked, enthusiastic blowjob, showing you special lingerie, even riding you begging you to cum (pov with and without dildo). She gets more giggly and crazy each day and she is the most crazy on the last day!
