your step-sis knows about your secret fun time with step-mom and she wants in. you'll be a good boy for her just like you are for step-mom. she doesnt want you to get good grades though she wants chores and errands done in exchange for draining your balls! she wants to be better than step-mom, will you let her? starts off slow with oil then edges and teases you demanding you dont cum until she says. when shes ready you explode into her hands. super long nails. one handed, one handed with ball play, and two hands used!
