Prompt: Emma secretly loves Regina's jealous streak. Sometimes she purpously seeks the green monster out.

Emma feels the way the air in the club shifts when Regina walks into the room. It's subtle, but completely noticeable – at least to her. There's an energy that comes with Regina that crackles through the air and seems to seek her out. Usually Emma moves toward it without thought, but tonight she stays put on her bar stool. Regina can come to Emma tonight or she can choose to stay away, Emma doesn't care.

It's not that they've had a fight, exactly. They certainly didn't scream at each other like they've been known to do and no punches were thrown, so Emma doesn't consider it a fight. But she's not sure what she does consider it, except another heated discussion about the fact that Regina can't seem to own up to their relationship in public, yet is possessive and jealous if Emma even so much as smiles at someone.

Yes, the mayor has a jealous streak that Emma is well aware of. And she actually kind of likes it when the green eyed monster comes out to play. But she'd never purposely play on Regina's jealousy just to get her riled up. That wouldn't be very good of her at all.

So when Michael approaches and offers to buy her a drink, Emma smiles and puts her hand on his arm and agrees because it's only the polite thing to do. Not because she has a bit of a bad streak in her.

And when Ashley trips over her heels on the way to the dance floor, Emma grabs her waist and holds her steady for longer than needed because she's a concerned friend. Not because she feels Regina's eyes burning a hole into her back the entire time.

And when Ruby announces she needs to go to the bathroom, Emma quickly links their arms and walks in the direction of the tiny ladies room in the back of the club because women always go to the bathroom together. Not because Regina has been moving steadily closer to her throughout the night.

And when she bumps into Kathryn – newly single and hoping to catch the local gym teacher's eye – she heads to the dance floor with her because if there's any way to get a guy's attention, it's by dancing with another woman. Not because the same is also true for how to get a woman's attention.

So she grinds against the blonde and laughs as they move. She likes Kathryn and she likes dancing and after the day that she's had, she deserves this. Ruby and Ashley join soon, so that they're all moving together, their bodies sliding against each other and their hands grasping body parts to stay upright. It's all perfectly innocent – Ashley is engaged, Kathryn is flirting with the gym teacher, and Ruby is well, Ruby – but to the jealous eye, it doesn't look that way at all. It's when Michael comes over – sweet Michael who's raising his kids now thanks to her – and replaces Ruby's hands with his own that Emma actually feels the air snap and crack under the force of Regina's jealousy.

Before she knows that's happening, Michael's calloused hands are replaced by Regina's smooth, strong ones. "I would appreciate it," the brunette snaps, "if you would keep your hands and other body parts off of my girlfriend."

Ashley, Ruby, and Kathryn all looked shocked, but their reactions are nothing to poor Michael's. "Y-your – your –"

"My girlfriend." Regina hisses at him, her tone so possessive that Emma thinks she might have pushed it just a little too far. But that doesn't stop the heat from gathering in her stomach or the wetness from pooling between her thighs.

"Regina –"

"And you," Regina's grip tightens, "don't think I don't know what you were doing, Miss Swan."

"I don't know what you think I was doing but I was just having a fun night out with my friends." Emma smirks.

Regina lets out a sound that's almost a growl. "Like hell you were."

"Regina –" she tries again, but it doesn't soothe the mayor at all.

"We're leaving. Now."

And as Regina pushes her out of the club, one hand firmly on Emma's ass and the other on her waist, Emma can't help but smile. Yes, Regina's got a jealous streak and Emma loves it almost as much as Regina hates Emma's bad streak.
