Oops, wrong hole

You feel Sam's cock close to your new entrance after she applies some lube, but she pauses. Before you can turn around to ask what's wrong, you realize that there may be something wrong. You look back to see a wicked smile on her face, before she enters your asshole instead of your pussy.

Your entire body tenses, as Sam elects to use the hole that you DIDN'T get overnight. "Sam what the fuck! Wrong hole!" you scream, flailing.

Sam just grips your hips harder, and starts trying to bury her dick deeper in your ass. You can feel every inch of her fill you up in what has previously only been an exit hole. "But Mark, I've always secretly loved your ass... Its so nice to be inside it, with a real cock no less."

"Sam, please..." you say weakly. "You're too big, and that's still my same asshole! You're gonna ruin it"

"I'm sorry babe, I don't really care right now" Sam seems to be consumed by her lust as she pumps her dick in and out of your sphincter, violating you. She grips your hips with each thrust, even slapping your ass like an actual girl!
