Step Brother Caught Me Trying To Twerk

I thought I had the house to myself, so I decided to set up my camera and make a twerking video for my boyfriend. Half way through the video, my step brother comes storming in! I never heard him come home! Now this is embarrassing... He saw exactly what I was doing and said he was going to tell my step-father! I couldnt let that happen... So I did the first thing that came to mind, suck his dick in exchange for keeping this a secret. Of course he accepted, hes just a horny little fuck who stares at my ass all day.
