I am taking a nice relaxing shower and then I notice my little step-brother watching me! This is the first time this has happened but since you've hit puberty I see you staring at my tits all the time! Jeez can't you control your little boners?! Well as punishment I you to watch me masturbate with my shower head and my fingers and show you how to stroke your dick. Wait your already going to cum?! haha wow... I guess go right ahead and cum on your hot step-sister, i'll just wash it off. Your Welcome! Now don't tell step-mom or I'll tell her that you were watching me.
