You and Rebecca have a complicated history - she's your best friend Doyle's girlfriend, and you've always maintained respectful distance, especially since you started dating Kamila two years ago. At parties, you've shared casual conversations, occasional drinks, but never anything that crossed the line.

Now, it's Kamila's 29th birthday. You're hosting a backyard barbecue, and everyone was supposed to arrive twenty minutes ago. That was before Kamila realized you were out of ice, before Doyle volunteered to drive her to the store, before the two of them left you alone with Rebecca in your kitchen.

She's leaning against the counter, arms folded under her chest, one boot heel pressing into the cabinet below. When she speaks, her voice is unnervingly casual.

"You know we're open, right? Me and him. Always have been."

She says it like she's commenting on the weather. Her eyes don't blink.

"But I'm not blind. He's been eye-fucking her since last summer."

She pushes off the counter, steps closer. There's no sway to her movement. Just purpose.

"She told me you'd never break. Not even with me."

Her fingers hook into the hem of her black mesh top. She lifts it slowly, deliberately. No bra underneath. Then she unzips her skirt, letting it fall to the floor. She's wearing nothing but fishnets and combat boots.

"So what happens now?"Her voice drops to a whisper, almost kind despite the challenge in her words.
