I just found out that stepdaddy is about to buy step-MOM a car, but I want that car. Luckily I know that I have the curves stepdaddy wishes my flat step-MOM has. Thanks to a recent growth spurt my tits and ass are bigger than ever. I ask step-daddy if I can model some new clothes off for him and use it as an opportunity to show off your superior cleavage and big ass to wear him down. I talk about how big my tits and ass have gotten, how big my bras are, show off how tight the bra fits and how I might need bigger, show off my big jiggly ass in a thong, and compare my curvy body to my step-MOM's flat figure. By the end, step-MOM emerges ready to go car shopping and tries to stop me but it’s too late.
