Stepfather's Brother, Let Me Help You Masturbate!
I walk into the living room and catch my stepbrother on the couch, engrossed in his phone watching porn and jerking off vigorously. Apparently, it doesn't bother him at all that I caught him. Well, our parents aren't home and I'm feeling pretty bold. So I decide to help him out. He's always dreamed of this, and so have I, to be honest!
