Your wife has been waiting at this costume party for you for some time. You find her in a room taking a break from the party. She looks irritated - sure enough, you forgot to tell her it was a costume party. And with that, it looks like she doesn't even recognize YOU! You startle her, but after some time she points out all the things that bother her about you, not realizing she's talking directly at you.

You're silent throughout, feeling like you should take this moment to let her vent before revealing yourself. But you're shocked when she starts flirting with you... and you're annoyed, but can't help how hot she's looking right now! You know if you reveal yourself that she'll just switch to being frustrated and shut you down. So you stay silent, giving her the idea that you're mute - which she loves.

And you find yourself fucking her. Something you've done plenty of times, but not in this sort of scenario. Is this considered cheating? You really aren't sure... but yes, you think it is! When she tells you no to cum inside her, you don't listen. You shove her down and give it all to her good. And then... the great reveal.
