Cheating With Your StepAunt

You and your wife are staying at your stepaunt's house for your stepcousin's wedding weekend and your wife gets into bed with you, buzzing from the rehersal dinner. Your stepcousin looked so pretty didn't she! She's going to make the perfect bride. And your stepaunt is so kind for putting the whole stepfamily up for the weekend. What? Why do you get funny everytime she mentions your stepaunt? Come to think of it, she didn't see you two speaking the whole evening. Are you scared of her or something? After a bit of gentle probing, she finally gets you to admit the real reason you avoid your stepaunt. Long ago, you accidentally saw her topless and you haven't been able to look her in the eye since. Your wife laughs and teases you a little for having a thing for your own stepaunt, but when she realises you've got a boner just talking about this, it seems to turn her on. You were worried she'd be offended, but she assures you she's not jealous. It's your stepaunt. You're allowed to have a thing for, it's not like anything could ever happen between you. But you want it to don't you? You're sexually attracted to your stepauntie, you perv! She gets down on her knees and starts sucking on your cock, amazed at how hard you are as she says filthy things about you and your stepaunt. She then climbs on top of you and tells you to imagine it's your stepaunt you're fucking, not your wife and it turns you on even more. You fuck her harder and rougher than you have before, leaving her with a huge creampie. The next evening, the night before the wedding, your wife and the rest of your stepfamily are in the living room getting merry when you decide to slip off to the kitchen to help your stepaunt with the dishes. She's surprised, but grateful for your help, and starts making awkward small talk until your hands accidentally brush. Emboldened by the touch, and still horny from the night before, you decide it's now or never. Your stepaunt is confused - she thought you didn't like her and now you're telling her you like her too much? What's going on? You grab her and pull her in for a kiss, giving her your answer. Your lips linger on each other's and she tells you this is wrong, but she doesn't put up any protest when you pick her up onto the kitchen counter and begin undressing her. The moment you've fantasized about your whole life is finally happening, with your unknowing wife just the other side of the door...
