A/N - Hey guys, just a heads up before anyone begins to notice, I'm British, so I apologise for any prior or upcoming mistakes when it comes to typically American things such as gun talk and sports teams because I am next to near oblivious, but I am trying. It also explains some difference in terms but I'm trying to be as authentic as possible here. Another note, just to say that I originally intended on this being a one shot, which is why Erin and Jay have jumped the gun pretty quick, I wouldn't have done that if this had started out as a proper fic. Thank-you such much for your continuous support, it means the world. I hope you enjoy! (Ps the next update will be a longer, Christmas chapter!)

"Hank," managed to escape Erin's mouth quietly as she removed Jays arms from her waist and stepped away. Jay, on the other hand, couldn't move. It was almost as if he had turned to stone, just gazing at Voight.

"My office, now." He signaled at Jay, leaving Erin stood clueless in the lockers, until Ruzek came in, bumping Jay's shoulder as he followed Voight silently out of the locker room, head to the floor through the unit and into his office.

"What the hell is happening there? He looks like a child ready to be punished," Ruzek laughed as he popped his head round from his door, not knowing that that was exactly what was probably going to happen. Erin just shook her head at him, like 'just don't ask' and he retreated to his locker as she left.

Jay expected Voight to shout, to be angry that he had ignored him. He did not expect what happened next. Once they got to his office, Jay didn't need asking to shut the door. Being locked in Voight's office, alone was terrifying. It flooded back the memories of last time, having his piece and badge stripped. He hadn't received any backing from Voight then and he wasn't expecting it now. By the time he'd spun back around to face his boss, he was leaning against his desk casually holding his own hands on his lap.

"So," Voight started, taking a big breath in that sent chills down Jay's spine. Most of him didn't want to hear whatever was coming next. "I've heard multiple accounts of how you got that shiner." He motioned to Jays eye.

Voight had just caught him with Erin in the lockers and he was moving his attention to the incident at Mollies, Jay wasn't able to comprehend straight away, he just stared awkwardly at the painting of the Chicago skyline that was sitting on the wall behind Voight.

"Kelly Severide was out of order, and I'm glad that you were there to stand up for Erin. She goes on like she doesn't need it but she's just like the rest of us, and sometimes she does need her partner when she won't admit it." Hank was still looking at Jay, with somewhat warmth compared to the harsh, brass reaction Jay was bracing himself for. It made him feel a little more comfortable, allowing him to loosen up a bit. "You have her back Halstead, and I appreciate that. You've become one of the few people I would trust with her life." He stopped again and Jay knew there was a 'but' coming.

"However, that does not excuse the fact that you blatantly ignored what I had previously said and that is something that I don't appreciate," he claimed as his tone of voice changed drastically, placing emphasis on the don't. All Jay could do was hang his head, nodding.

"I'm going to say again, just to be crystal clear. This is my unit, my rules. While you're both up here, I won't tolerate whatever you two think you have going on here." The end of Hank's mini speech sounded pitiful, almost as if he had some sympathy for Jay, which made him feel like it was worth a shot to try and argue his ground.

"C'mon boss," he began to plead, desperation plaguing his voice. "If I'm one of the few you trust her with, why would you want anyone else with her? I am sorry for going against you, I really am but, I can't explain it," he sighed, taking a moment for air. "I just couldn't help it."

"That's exactly why Jay, you cover her back every day. We can't risk puppy love clouding your judgement or efficiency on the job to put either one of you in danger." Jay understood wholeheartedly, he wasn't going to bother explaining why it would be the complete opposite. He put his all into protecting Erin already but it would be so much more if they were together on the job. "I don't want to lose you Halstead, you're really becoming great police and you're an asset to the team, honestly. So you can stay, or I can transfer you, but Erin only comes with one of those options.

As gutted as Jay was, he didn't have to think twice. Intelligence was his family. They had molded him into an amazing detective, and allowed him to channel military skills like sniping into something he loved. They support him, most of the time, and helped him grow through difficult ops but after last night, and Erins episode at the lockers, there was no way he was going to pass this up. He thought of the electrical impulses that her touch sent through him while she pressed against his bare chest; the way her fingers played his body like a violin when she traced over his veins and the words just blurted out, out of his control.

"I'll take narcotics, boss," he looked up at Voight, "if that's possible? If not then intelligence in another district would be preferable."

Hank was shocked, he took a moment to take it in. Last time they had this conversation he had been speaking to a naive, infatuated boy obsessed over a pretty face. This time, he was facing a mature, adamant detective who knew what he wanted and he was kind of impressed. He reached out to shake Jay's hand firmly. "I'll see what I can do. You take care of her Halstead. You can stick together until you leave, there's no point switching up partners now."

"You know I will." And he walked out of his office just like that.

He had noticed it getting dark through Voight's windows but he hadn't expected every desk to be empty when he walked out but truth be told, he was quite glad that that was case. He reached for his keys off his desk without looking, but his hand met smooth, oak wood and paperwork. He wondered where the hell they'd gone for a second, but on a whim he walked out to the car park instead and found exactly what he had expected to.

He opened his passenger door, since Erin was unsurprisingly in the driver seat, hands on the gear stick as she was preparing to drive as soon as he got in the car.

"Well?" she asked, looking anxious as he placed his hand over hers. He slipped his fingers between hers before pulling her hand up to kiss it.

"I still only have one black eye," he joked, stifling a little laugh, warranting a smack in the arm from her. "In all seriousness, he's okay with it," he paused as she interrupted him with a sigh of relief, not expecting him to come in with an anticlimax. "But, I have to transfer."

He watched as the glimmer of hope washed out of her eyes, killing him a little inside.

"I've asked for narcotics, I'm not giving you up now Erin." He smiled at her, and her lips curled at the sides forming a little smile back but she couldn't bring herself to form a full one. Devastation flooded her body as she realised she wasn't going to have her partner at work, at the same time it was counteracted by the happiness that overwhelmed by the decision for her. She was such a mixed bag of emotions she couldn't even reply, she just drove as he continued to explain that Voight wasn't going to pull them apart just yet, he was going to wait until everything was finalised with his transfer, which made her just that little bit happier.


Jay was able to tell that Erin was down about the fact he was switching units for her, but he knew she'd appreciate it in the long run even if she held it against Voight for a while. In the meantime, he was doing everything he could to try and cheer her up a little bit more, to rid the hint of upset in her voice that made his stomach sink. A quiet night in was on the cards, the first one they'd be able to do all the stuff they'd been dying to since day one. Simple things like have her lie in his lap or curl into his arms ran through his head as he carefully chopped mushrooms and peppers, preparing something special for her while she ran her shower.

'Hmm, shower,' he thought, a little lightbulb went off in his mind. He ditched the veg on the worktop and rushed into his room. Erin was a weird one, she always left the bathroom door open when she showered, even when they weren't together. He stripped down in her bedroom, shuffling his clothes into a corner to avoid making a mess in her somewhat tidy apartment and waited for her to turn her back to the door as she mumbled her way through Sweater Weather by The Neighbourhood.

The second he saw his chance, he opened the shower door and slipped in behind her. He could almost see her smile from behind as she felt his presence, running her hands through her hair but continuing to sing quietly, acting like she was oblivious to the idea she had company. She took a big breath in and braced herself for his touch causing the hairs on the back of her neck to spike up.

"Touch my neck and I'll touch yours."

He lightly ran the tip of his tongue from the base of her neck to the bottom of her ear before placing his hands on her soapy hips and slowly ran them up her body. The fell into all of her curves of her waist as they inched their way further north.

"The goosebumps start to raise the minute that my left hand meets your waist."

He took over the lyrics from her as he followed the shape of her body all the way up past her chest and her shoulder blades as he traced up her arms. She went to turn around and face him but he stopped her before she could.

"Nuh uh," he whispered in her ear, giving her shivers. He pulled her arms down from behind her head and placed them on the small of her back, cuffing her wrists with his hands and turning her towards the wall, allowing him to stand beneath the flow of water. He gently pressed her against the tiles, making her gasp loudly as her bare body was met with cold. The tiles were cold but her body felt like it was on fire when she realised he was holding her in an arrest position, it was kind of hot and made her tingle everywhere. She was out of reach from the falling water but Jay stepped closer to her, pressing himself against her so she was pushed into the wall a little harder and she could feel the shower trickle between them.

"Erin Lindsay, you, are under arrest," he sighed into her ear, a hint of dominance in his voice.

"Oh really, Detective?" She played along as she turned her head to face him in a desperate bid to make eye contact. "I'm not sure what I've done," she said innocently as he gently nipped the skin between her neck and shoulders with his teeth, making her gasp lightly, "but I'm sure I can make it up to you." Before she even finished her sentence,she tiptoed and stuck her ass out ever so slightly, causing her back to arch but more importantly to grind a little against his crotch. She felt him jump as he felt her against him, causing her to smile.

"Oh," he growled, painting a devilishly handsome smirk across his face as he let her go and spun her around. This time, her hands were free and he was towering above her, one arm resting on the wall. "What makes you think that, huh?"

The way he stood brooding over her made her feel something she'd never felt before, almost submissive. Whatever it was, it was turning her on crazy amounts and she didn't want it to end.

"This," she said, refusing to break eye contact as she placed her hands on his chest and started running them down his body, planting little sucks and kisses down the trail that her hands were leaving. Jay took a heavy breath in to prepare himself for the rest of their shower.


"Well," he laughed as he wrapped a towel around her as she stepped out of the shower, "I never expected that to go as well as it did."

"I never expected it at all so you definitely one-upped me," she fired back as they walked into the kitchen, leaving a dripping trail of water behind them. "You were even cooking dinner," she glanced over to the granite worktop, "I could get used to this Halstead."

Closing A/N - I had the shower idea earlier today, but writing it was so difficult because I didn't want to go into loads of detail so I apologise if it's badly done, I hadn't a clue how to end it either. Let me know what you thought of Voight's reaction and what you think/want to happen!
