Sisters Olivia, Sophia are doing yoga when Olivia realizes Sophia has a hole in her yoga pants. What starts out as playful banter between siblings turns into a sexual experience, with Olivia fingering Sophia's pussy. Unfortunately their stepfather is spying on them from his bedroom doorway, stroking his cock to his stepdaughters and recording them. When he makes a noise, the girls run at him, grabbing his phone. Olivia begins to record him, and that's when the girls get an idea: they'll ruin him.
