Your step-sister catches you jerking while she's doing laundry but she doesn't care! "It's only weird if I'm naked while you jerk it. You can jerk as long as I have panties on," she smiles, sliding her tiny short shorts off. She goes through her laundry while she teases you, asking you to sniff her panties to see if they're clean and shaking her butt in your face. The stop and go builds up after a while, and your step-sister feels bad for not letting you relax. "I know exactly how to make you cum," she says teasingly.
