I was on the phone with my best friend, telling her how excited I am go out dancing with her tonight. I wore a special sexy outfit and can't wait to meet a guy! I brag on the phone about the naughty things I love doing to guys. My step-dad overheard me by my bedroom door and interrupted me. He was supposed to be at work but he stayed home without telling me. And he was in his underwear yelling at me and I find him annoying! Then I stayed in and went to bed inside. I got so horny thinking about his bulge in his underwear that I masturbated and moaned saying "step-Dad" a couple times. I got too loud and then my step-dad caught me! I don't want him to tell step-Mom and I will finally make him feel like part of the stepfamily as my step-Dad! So I suck his dick and ride him topless until we cum (implied).
