You are stepMommy's! So small and helpless. stepMommy can do filthy, nasty things to you! You love that, don't you? You love knowing stepMommy can do whatever she wants to you! First I'm going to put you in a diaper! I'll cover you in powder. Then I'll push this big plug into your little butt! It's going to stretch you open and fill you up and there's nothing you can do to stop me!
Enjoy!
