A young and horny teen stepsister is bored and decides to spy on her stepbrother while he masturbates. She sneaks into his bathroom and hides behind the shower curtain, watching him stroke his hard cock. The brave stepbrother doesn't notice her at first, but as he gets more turned on, he starts to hear strange noises coming from the bathroom and realizes that someone is watching him. He turns around to see his stepsister hiding in the corner, with her hands down her pants, rubbing herself to orgasm. The young girl is too turned on to stop now, so she decides to join in on the fun. She drops to her knees and gives him a blowjob, making him moan with pleasure. The stepbrother can't resist her seductive moves any longer and he takes her from behind, fucking her hard and fast.
