Your nerdy STEP-sister wants to have a Star Wars marathon while your step-parents are away, she’s all ready and dressed up in her sexy Darth Vader costume. You take one look at her body in that outfit and are immediately erect. Her plan is working, she starts to tease you by shaking her ass and then eventually showing you her tits. She gives you some jerk off encouragement for her before sucking you off for a bit. She then tittyfucks you for a couple minutes, before finally letting you give her a facial.
