You and your step-sister have been watching a series and tonight is the finale. She comes in wearing a dress and lays on the bed in front of you after turning it on. After a bit the show takes a strange turn. Showing sexual scenes that make you feel uncomfortable. As the show goes on with even more sexual content she finds her satin panties pressed up against your boner. You both allow things to naturally happen which turns into lot's of heavy breathing, rubbing and finally penetration. You both orgasm and she collects her clothes telling you that she isn't mad it happened, but needs to think about what just transpired.
