I'm on my bed filming myself masturbating when my step brother walks in my room and is shocked by what he sees. I quickly stop and pretend I am just checking out and adjusting my panties. He asks what I am doing and I quickly make up something and tell him I was just trying on some new underwear I bought and testing how comfortable they are. He jokingly says he first thought I had nothing on and was doing something else..... watch to find out the rest ;)
