We danced the night away

We drank too much

I held your hair back when

You were throwing up

"You know you're going to regret this tomorrow right?" Jay chuckled watching from his seat at the bar as his girlfriend downed her fourth shot in twenty minutes, her best friend doing the same thing.

"Come on Halstead, have a little fun!" Erin exclaims playfully slapping her partner's shoulder from where she stands in front of him "You got to learn to loosen up a bit babe."

Jay just shakes his head, wrapping his arms around her waist and pulling her in close to him "I tell you what; I'll sit out and be boring and look after you tonight, and then next time we can swap. Deal?"

Erin grinned cheekily, leaning down to quickly peck his lips "Deal."

Jay watches in amusement as Erin quickly turns back around to Kim and high fives her before yelling out to Gabriella Dawson for more drinks. Jay can't help but think back to the first day they met, she was still as demanding as ever

...

"What do you think you're doing?" Erin said as they walked to the car.

"Getting in the car?" Jay stated confused.

"You're getting in on the driver's side." She replies.

"Is that a problem?" Jay asks again.

Erin chuckles shaking her head "No no, I'm driving."

"What? Why?" Jay says.

Erin simply gives him a hard look before stating "Because. I. Drive."

Jay puts his hands up in surrender, walking to the other side of the car "Whatever, I'll wait my turn."

"You're going to be waiting for a long while buddy." Erin laughs starting the car and pulling out of the precinct.

"This is going to be an interesting partnership." He sighs looking out the window.

...

Erin had always been in the driver's seat, in both their professional and personal lives. But he wouldn't change it for the world. He liked how their relationship was, and how it worked. They both knew each other, and how their partnership worked. Erin had opened up so much since their first argument that day, and that's all he ever wanted.

"Yo, you may want to keep a check on your girl." Mouse nods his head in Erin's direction.

Jay's head snaps up to look at his girlfriend again holding a whole tray of drinks and walking over to a booth full of their coworkers. Jay just smiles again looking at his best friend.

"It's all good, we have an agreement."

"Jaaaaay, you have to dance with me!" Erin whines as Jay is gently pushing her out of the bar.

Jay rolls his eyes; it's the eighth time she's said that to him in the few steps they've walked from the bar towards the car. Jay had let Erin have her fun, but the second she was declaring a table-top dancing contest, he had reached his limit. There were many things Jay Halstead could handle, a bar full of men eyeing up his girlfriend was not one of them.

"Come on Er, you can dance when we get home." Jay talks softly to her.

Erin groans and flings her head back dramatically "That's forever away! I want to dance now!" She stomps her foot like a child and Jay lets out a sigh, feeling both frustrated and amused with his clearly intoxicated partner.

He knows he's going to regret it, but it doesn't stop the words "Fine, let's dance."

He takes her left hand in his right, holding it up as his right hand wraps around her waist. Erin giggles drunkenly as Jay begins to sway them around the sidewalk outside Molly's, humming a tuneless melody as he moves them around in circles. A laugh breaks through as he sees the pure childish excitement on Erin's face as she looks up at the stars while trying her best to keep up with her boyfriend in her drunken state.

They sway for a few more minutes, Erin's head now resting on Jay's head and he can't help but smile at the content feeling that washes over him as he takes in the moment. Dancing around on the street with his drunk girlfriend. It was something only they would think normal to do.

"Jay?" Erin's voice breaks through his thoughts "I don't feel good."

Before he can process the words Erin is hunched over and letting out the alcohol she's consumed over the past six hours since arriving at Molly's. Jay quickly rushes over and holds her hair back, rubbing her back as she coughs up more vomit.

And yet he still can't stop chuckling to himself; this is most definitely something that would only happen to them.

"Hey there sleepyhead!" Jay exclaimed as he spied into their bedroom the next morning.

Erin groaned and pulled the blankets further over her head "you're an ass."

Jay chucked watching his girlfriend "oh come on, I brought you a combo." Jay said putting the bag in front of her "you know grease settles your stomach."

Erin slowly sat up and reached for the bag and quietly eating her burger "you're the best."

"Oh I know." Jay smirked sitting down next to her on the bed "how are you feeling?"

"Better now." Erin smiled "I'm sorry I got so out of hand."

"It's ok. I don't mind holding your hair back when you're puking your guts out on our bathroom floor." He laughed when Erin dropped her head onto his shoulder and groaned, embarrassed she hadn't even made it to the the toilet before she emptied her guts out.

"I'll clean that up, I promise." She said quietly and Jay leaned down and kissed her head softly.

"I already got it, just remember this for when I'm the one throwing up. It's my turn next babe."

Erin looked up at him and smiled slyly "don't worry Hun, I'll hold your hair back for you."

"My hero." Jay sassed back, his eyes lighting up with the familiar memory.

"My hero." Erin muttered sarcastically as she passed him back his gun and badge "you're still not driving."

Jay sighed and watched as she walked away from him and got into the driver's seat of the 300, following after her glumly.

"Well, since you're such a good house husband, I might let you drive this time." She said leaning over to kiss his lips quickly before turning her attention back to her burger, Jay watching on amused.
