You walk in on your step-sister crying in her bedroom. God, she's such a slut. Wearing a tiny pink dress and talking about how she doesn't know how to have a threesome. Well, you'll teach her how. You grab the dildo and give her the time of her life. At the end, you cum in her mouth and she keeps it widdeeee open for you to see how much of a load you've given her. She swallows and gasps, realizing what you've done.
