You find out about your step-Mom's secret affair, so you take advantage of this situation by telling her if she doesn't do exactly as you say, her secret will be out! step-Mommy has no other option but to obey your every command. You degrade and humilate her by calling her names like cum slut and whore etc. step-Mommy sucks your dick, degrades herself, calls herself names and rides your cock showing off her big ass! You blackmail her even more so that she lets you cum inside her, and promsies to keep fucking you as much as you want!
