It is your pussy now, fuck my fat ass

I come into your room fully aware that something is wrong. You are my stepson after all, I know when something if up. You tell me your having girl trouble. Admitting you like curves and the last one just did nothing for you. You shyly ask me to let you wank to my ass, reluctantly I agree, but decide no touching. I am shocked at how hard you are, slightly flattered, I allow you to grab my ass, and don't complain when your hand slips inbetween my pussy. You begin to fuck my hard from behind until I am moaning out loudly and cumming on your cock. Custom name mentioned throughout. Step verbiage not used throughout the clip. Ends in creampie.
