Amelia Anderson, the naughty step-sister, thinks she's alone in the house. She sneaks into the bathroom, locking the door behind her, eager to relieve her pent-up desires. As she strips off her clothes, she starts to touch herself, her fingers circling her clit, then dipping inside her wet pussy. She's lost in her own world, moaning softly, when suddenly, the door creaks open. Her stepbrother has caught her in the act, and the look on his face is priceless. Amelia, embarrassed but turned on, decides to put on a show for him, her fingers moving faster, her body writhing. She knows she's being bad, but the risk of getting caught only turns her on more.
