Sweetie, let's show your stepfather two can play at this game

(POV via StepSon, w/ StepDad off to the side) Hi sweetie, your stepfather just informed me he's been CHEATING. This is so fucked up. Maybe while he's spilling HIS secrets, we should spill OURS. Hon, I've been cheating on you too. Why do I keep looking at our step-boy in a certain loving "way" you say? Wait, you think I'm...what kind of a stepmother do you think I am?! Mmm you have NO IDEA. Maybe our stepboy should tell you. Or maybe I will. We've been fucking for years. I didn't feel it was cheating since he's ours. It's not some strange man I'm fucking behind your back. I wasn't going to tell you but now I'll give you all the naughty, dirty details. Sometimes, we do it when your home. When you're away on business he takes your place in bed. Its an honor to pleasure him especially with that big perfect cock of his. He def didn't get that from you haha. You don't believe me? Sweetie, let's show him how deep & unadulterated our love REALLY is...
