You; Beti

You were happy when Tegan got a job at the local high school. Sure, it didn't pay the best, but she loved the job!

Well, her enjoyment had been rather short-lived. After a few days, she became the rather for her "rival," Beti. Beti always seemed ready to undermine Tegan or fuck her over; it was like that even been when you were all in school together. Your wife did her best to not let it get to her. "She's just some fat bitch who's taking her dissatisfaction with her own life out on me. It'll pass." That was the line Tegan would use to help calm both you and her down.

Then came the work party. She figured it would be her time to shine! After all, she could wear something sexy and show you off, too. "Knock 'em dead, babe," you said, kissing her as the two of you got out of the car.

"Love you," she said, her voice wavering a bit.

"I love you too. It'll be just fine. You'll be the belle of the ball!" You gave her a bright smile as you took her hand and walked in to the building. You were right, of course. Her tight black cocktail dress really drew attention. Unfortunately, it also drew the wrong kind of attention.

"Look at the bimbo, slutting it up," a sensual and stern voice said from behind you.

It was Beti.

"Hey, don't talk about my wife like that," you shot back. Beti simply smiled and bit her lip. She made sure to accentuate her generous cleavage as she looked at you.

"Well, well, well: it seems this hottie has a bit of fire in him. How's about you ditch the boring slut and come have a good time with me?" Beti teased, shooting you a wink.

"In your dreams, Beti!" Tegan replied. "We all know you're just jealous of anyone with a stable relationship because your fat ass can't land you a good man." Your wife squeezed your arm. That seemed a little harsh, but Beti didn't even seemed phased.

"Oh, I'm sure that's it, washboard." She started to walk past the two of you before stopping by you, "if you happen to want to end the night with a real woman, come and find me." It was loud enough for Tegan to hear it, but before she could fire off another reply, Beti walked off.

As the night wore on, the two of you didn't see Beti at all. She was probably avoiding you after the verbal lashing Tegan gave her. The two of you were finally able to let your guards down and enjoy the party.

Tegan had wandered off to talk with some of her coworkers while you sat at the bar. "Fun night?" An all-too-familiat voice cooed from right next to your ear. You instinctively flinched away before turning to see Beti taking a seat next to you at the car.

"What do you want?" You scoffed, mostly ignoring her while you nursed your drink.

"You," she replied with a Cheshire grin.

"What?" You nearly spat out your drink.

"Here's what's going to happen, Mr. Perfect: you're going to come with me to one of the classrooms, I'm going to give you the best fucking of your life, you'll fall head-over-heels for me, you'll leave your wife and you'll become my slut husband." She rested her hand on your crotch, feeling your hardened cock.

You let out a gasp, but tried not to be noticed. "W-why would I do any of that?"

She gently nibbled on your ear, gripped your crotch tighter. "Because I said so. And I always get what I want. You're going to be mine and there's nothing you can do about it."

You weren't sure what was making her so confident. You had no intentions to follow her... Even though her dress hugged her plus-sized body quite beautifully. Her large tits were almost completely on display and it was taking everything in your power to avoid looking.
