I wrote this one shot for tumblr but I thought I'd post it on here for you guys. Enjoy
Nadia raced over to Erin with a beanie filled with folded up pages of notebook paper. Erin glanced down with a quizzical expression worn on her face. Nadia pushed it closer towards her friend, "It's your turn." She insisted, giving Erin one of the biggest smiles she'd ever produced.
"I don't really do Halloween." Erin reminded her, turning back to her paperwork. Nadia followed her around to the backside of her desk, falling to her needs and folding her hands together. Her eyes were pleading like a child in manipulation mode. Erin rolled her eyes. "It's not going to work."
"Oh come on Erin, don't be such a party pooper." Jay teased from across the room. She shot him a look, one that said if he spoke again she'd poor his coffee right down his front. He held a hand up in defence and looked back down at his work.
"I've never had a Halloween party before." Nadia played. She wanted to guilt Erin into getting involved but of course she wasn't being cooperative.
"What's in the hat anyway?" Erin asked. Her attention didn't leave the page she was writing on, but Nadia could feel her starting to take an interest.
"They're what you have to dress up as." Nadia explained, pulling out the piece of notepad she'd drawn herself. It was crumpled up inside her pocket, she smiled and began unfolding it.
"See! I'm going as Pocahontas" She showed her excitedly. Her whole body bounced in excitement, and it was near impossible to keep from smiling when Nadia was like this. Erin hated giving in after putting her foot down but this time she made an exception.
"Alright, give me one."
Nadia reached down to grab her beanie quickly, holding it out in front of her ready for Erin to make her selection.
Erin slid her hand into the hat with a undeniable resistance, she felt around the slips of paper as if she could blindly feel for a good costume. She pulled one up and began to unfold it. She read the name scrawled over the small piece of paper and gave Nadia an unappreciative stare. "Sandy from Grease. Really?" She scowled; this was a stupid idea even more so now that she was being roped into dressing up in a cat suit.
"I'll see you tomorrow night at Molly's." Nadia smiled, trying to brighten up the mood that Erin had just left in the room.
Everyone acknowledged Nadia's invitation, since they had all already fallen for the costume trap. Alvin walked past Erin's desk, she flagged him down. "Did she get to you too?" She asked, honestly thinking that the apocalypse would arrive before anyone could convince Alvin to dress up for Halloween.
He looked at her, "You're young you should be thrilled at a chance to dress up." Erin turned her head sideways, he wasn't answering her question.
"I unfortunately cannot make it, I promised my daughter we'd do something special that night. Such a shame, right?"
Erin's mouth gaped open, she stamped her foot against her desk. This wasn't fair. How come Alvin got a free pass out of this nonsense? Alvin chuckled as he kept walking towards the break room.
It was a struggle but Erin managed to find something to Grease herself up the following evening, she looked ridiculous and that was an understatement. It was bad enough that she was going to a party that celebrated such a childish holiday, but now she was dressing up and participating just to prove that she wasn't a party pooper? She groaned as she stared at her reflection, she refused to wear the heels. She'd decided instead that Sandy 2.0 was more practical, and wore boots with her skin tight suit. She played around with her bra, making sure she at least looked alright up top, if she was going to be wearing something this tight she wanted to at least put out a good impression of herself since none of these people would ever see her dressed like this ever again.
Kim had snuck over to help her curl her hair, which was fine with her since Voight hadn't exactly taught her how to do all of that stuff when she was younger, but while Kim was getting changed into her slutty nurse costume in the other room, Erin was mildly freaking out.
"Hey Kim do you think maybe I should just forget the whole thing?" She called out to her friend. Kim stuck her head between the door and the wall and shook her head.
"Absolutely not, tonight you're going to rock that outfit and have a great time." She promised, pushing the door out of the way to reveal her own costume.
Erin whistled, "You're not going home alone tonight." She told her, indicating for her to spin around. "You look smoking hot."
Kim's face lit up, and a smile spread across her ruby red lips. Erin turned around to look at her reflection one last time. Kim walked up beside her and smiled at the faces that looked back at them.
"Let's go and get drunk." Erin declared. That was the only portion of the evening she was looking forward to.
The music was already pumping; Erin could feel it as they walked down the footpath towards Molly's. She gave Kim a small smile still unsure of herself. She'd been walking with her head down trying to avoid spotting her reflection in a window. "Stop worrying, you look great and tonight will be great too. You'll see." Kim told her as she walked into the bar. Erin took a deep breath before following her inside, her vision was filled with costumes of plenty, she chuckled to herself as she spotted Kelly dressed as a farmer. He waved at her before turning back to the conversation he was in. She scanned the room looking for a spare place to sit, when she spotted Nadia who waved her over.
"You look cute." Erin complimented the younger woman who had wrapped her arm over Erin's shoulder in an awkward sideways hug. The two girls sat down beside each other, Erin on the outside and Nadia against the wall of the booth.
"I thought you were going to bail." Nadia said straight into Erin's ear. Erin looked at her with a raised eyebrow.
"Well I didn't, but I'm going to need a drink." She told her, standing up.
"Oh yeah me too." Nadia nodded, Erin placed her hand on Nadia's shoulder.
"I'll get you a soda." She chuckled, reminding her that she was a cop, and there was no way she would let her get away with drinking under aged.
Nadia sighed, "Fine."
Erin walked away laughing, she slipped in beside Kelly who was talking to Hermann behind the bar. She gave Hermann a look that said she needed something heavy. He nodded and excused himself.
"Didn't think dressing up was your thing?" Kelly teased her when Hermann had left to make her a drink.
She smirked, "Well I'm here and you're not allowed to tease me."
"If I do will you arrest me?" He flirted, the pair had dated on and off unexclusively for months, that was until Kelly had met some new girl who he was convinced he was now in love with.
"You bet your ass." She played along, as Hermann placed a glass in front of her. She had almost forgotten to get Nadia her soda, "Can I get a coke too? The hostess is only 19." She explained and he grabbed another glass.
"So um Sandy, it looks like Danny's here." Kelly motioned towards the entryway of the bar. Erin swiped herself around to see Jay walking in, wearing black slacks and t-shirt and a cream varsity jacket, his hear was even slicked back with an excessive amount of hair gel. Her mouth fell open.
"Will you excuse me for a moment?" She asked Kelly, taking a large gulp of her drink and placing it back on the counter. She quickly stormed over to Nadia, yanking her by the arm. "Is this your way of playing cupid?" She asked angrily, pointing over to where Jay was talking to a few of the firemen.
Nadia shook her head nervously, "He picked it out of the hat like you! I swear."
Erin groaned and marched back over to her drink. "I shouldn't have come." She muttered, downing the rest of the liquor.
Kelly chuckled, "Come on, it's pretty funny. What are the odds?"
She glared at him, why did everyone find this so amusing? The only thing that could make her night worse would be if Jay noticed their matching costumes and quoted the movie to her.
"Erin." A voice behind her spoke before she had a chance to escape. Kelly had to look away to stop himself from laughing.
"Jay." She smiled politely, nodding toward Hermann for another drink.
"Are you wearing lycra?" He asked in amusement. Erin moved a strand of her hair away from her face and shrugged.
"Maybe."
He chuckled, taking a swig from his beer. "It looks good on you."
"Don't make fun of me Jay, I already want to go home." She warned, having had enough already.
"It's not that bad here is it?" He questioned her, making his way over to a spare seat, she didn't know what came over her when she followed him but somehow she found herself sitting opposite him in a secluded portion of the bar.
"Depends what you define bad."
"You look hot, every man in this bar has checked you out at least twice, there's alcohol and you have good company. What's bad about that?" He grinned, the room was crowded and everyone sounded like they were having a good time, she sighed and decided she just needed to relax.
"I look hot?" She smirked, playing with the straw in her drink. Jay winked at her with a sleazy grin on his face. She couldn't help but laugh.
A table filled with empty bottles and stacks of shot glasses was the result of Erin and Jay trying to have fun together. They'd literally drunk the night away, and the bar was starting to empty. The pair were laughing and joking until Gabriella came over to collect the empty glasses.
"Do you need me to call you a cab?" She asked, and Erin shook her head. "I think you two have had enough for one night."
Erin rolled her eyes, "Okay fine." She said groaning. She tried to stand up, almost landing face first on the floor.
"I'm calling you a cab." Gabby told them, reaching for her phone.
Erin looked over at Jay and smiled, "You want to come over?" She asked him in a soft sincere whisper.
Jay nodded. It was a deal.
The pair fumbled up the stairs of Erin's building. Erin kept laughing hysterically and Jay was holding onto the walls to keep himself from falling over. Erin threw her purse at him demanding he find her keys, he obliged and jammed them into her apartment keyhole.
It took him a few attempts to unlock it in his drunken state but as soon as the door opened Erin pushed him inside.
Her hands started tugging at his shirt, he helped her pull it up over his head. She slammed the front door closed and pulled him towards her bedroom. "You're all mine tonight Mr Halstead." She purred, kneeling down on her bed.
Jay stood at the foot of her bed, wrapping his arm around her body trying to find the zipper to her suit. He couldn't manage to work it which frustrated him. "First of all, it's detective." He growled into her ear causing her to giggle. He pushed her back onto the bed and straddled her. "And second, you're all mine." He corrected before crashing his lips against hers.
Erin was excited, her hands snaked their way down his bare back, feeling for every nook and cranny that made up his sexy body. She slipped her hands into the back of his pants and giggled against his lips as he reacted.
He rolled onto his back, her now on top of him. She stripped out of her Sandy clothes and climbed back onto him with only her underwear left. Jay's eyes were black with lust while he watched her unhook her bra seductively. He let out a stifled moan, so she leaned down on top of him.
She trailed down his torso with hot, wet kisses, pausing just under his belly button she ripped open the top button of his black jeans. "Erin." He whimpered in anticipation.
She giggled. "Shh stud." Jay's eyes rolled back into his head when she started teasing him through his boxers, this over drove her to keep going. Like he was egging her on.
"Cock your gun for me detective." She cheered, pulling down his pants completely, Jay didn't even hesitate, he kicked them off as quickly as he could manage and pulled her on top of him again.
Their kisses were sloppy, but neither of them cared. They were still completely wasted, Erin rubbed herself against him wanting more. He groaned, running his fingers up and down her naked back.
She straddled him finally, and moaned when he pushed himself into her, they couldn't control their hands, still exploring, still wanting to feel more. Erin called out his name, something she'd been wanting to do for a while. He thrust into her, and was rewarded by a series of moans that escaped from Erin's lips. She arched her back from pleasure, digging her nails into his skin. She was a screamer, something Jay had never imagined. He took advantage of the fact, hitting her in all the right spots. She screamed out when he came, telling him that they were definitely doing that some time soon. He chuckled, the energy he was just using had started to fade. She slipped herself off of him, and curled up into his muscular embrace. She yawned, snuggling into his chest thinking to herself. Maybe Halloween wasn't so bad after all.
