Stepsis Wants To Deepthroat Stepbro's Throbbing Cock

A Boner?! Why the fuck does my stepbro have a boner?! Well, fuck it, I guess - if he can’t get rid of it, I guess I should be a good stepsis and help him. I never imagined myself on my knees, his big, throbbing cock working its way down my throat. I thought that would be the end of it, but I couldn’t get the image of his dick out of my mind. I knew I needed more. Soon, I was fantasizing about being his little slut and milking him dry all the time. Would that make him happy? To have a sweet girl in his life who is always ready to please his cock? I think so… especially when that girl is his eager, horny stepsister.
