HD - Im getting ready to go to a costume party and I am horny, so I start masturbating then I hear someone at my door. I look up and find my brother watching me. I tell him to come in and close the door. I then tell him I am going to tell dad what a perv he is and that I don't feel safe in the house and he should throw him out. I explain that I won't tell if he jerks off for me. To be honest, I am not even upset that he was watching, I am mad because he saw his sister was super horny and didn't offer to help.
