Hope is restrained in her house awaiting her boyfriend's return so they can enjoy some kinky sex together when suddenly Scarlet shows up to find her step-sister naked and at her mercy. Intrigued by her little step-sister's predicament, Scarlet sits down next to Hope and notices some lube and a vibrator on the floor beneath her exposed pussy. Hope assures Scarlet that this is just a back massager but Scarlet insists they see what kind of fun they can have with it. As Scarlet drizzles lube over her step-sister's clit and presses the vibrator firmly against her crotch, Hope struggles to maintain composure knowing that even with her step-sister present she could never suppress her arousal as her moaning reaches a crescendo and her pussy begins to glisten with her flowing juices. Each time Hope cums, Scarlet grins knowing what a slut her step-sister is that she can't even control herself around her older step-sister. She loves to watch Hope's entire body quiver after each orgasm.
