You're step-daughter has been behaving oddly and you suspect she might have a substance problem, so you set up a spy cam in her room. You don't see any illicit substances, but what you find out is even more surprising! You listen in on her phone conversation with her friend where she talks about how hot her step-dad is and how she wishes you would spank her! When she hangs up, she starts to touch herself and as you watch and listen, you hear that she's calling out for you even as she cums on her fingers!
