Hi guys, welcome back.

Warning: This chapter is another M-rated chapter and contains smut.

Thank you once again for the feedback on the last chapter.

I hope everyone enjoys this.

"Good morning Hailey." Rojas greeted from the couch as Hailey stumbled through the door after spending the night at Jay's apartment. Hailey headed for the kitchen in search of coffee, Rojas joining her and the two sat around the island.

"How was your date with Jay?" Rojas questioned, Hailey's face lighting up slightly hearing Jay's name mentioned, something that Rojas noticed.

"It was lovely. He took me Marco's steakhouse down by the river, we had our own little private room, it was so romantic and perfect." Hailey explained while trying to contain the big giddy smile that had formed on her face.

"I'm really glad that you enjoyed yourself, it's about time he took you out on a date." Rojas chuckled, Hailey laughing slightly as well.

"I didn't mind waiting, he said he wanted to make our first date perfect and last night was perfect. We also agreed to move in together as well." Hailey responded excitedly, Rojas's face lighting up hearing the good news.

"Ah that's great news, I'm really happy for both of you. He's been living here since he left hospital anyway so it was only a matter of time before you moved in together." Rojas replied.

"We were talking last night and we thought that you could take Jay's apartment if you wanted. Obviously I love having you live with me and we're not trying to get rid of you but I thought I would be nice for you to have your own place. If you don't want that then you can obviously stay here, I'm not going to throw you out just because Jay's moving in." Hailey rambled on trying to not seem that she was trying to get rid of Rojas.

"Hailey don't worry, I'm so grateful for everything you done for me, letting me stay with you while means a massive amount to me. You're right as well, it's probably time now that I get my own place and give you and Jay some privacy. What's Jay's apartment like anyway?" Rojas reassured as she gave Hailey a warm smile.

"His apartment is nice, it's nothing to fancy but it's fairly new so it's quite modern. I'm pretty sure it's not too expensive and from what Jay's told me the landlord is a really nice guy so you wouldn't have any problems from him. So if you were interested we could change the name on the lease and you could move in whenever you want, Jay doesn't have to much stuff in there so it wouldn't take long to move out." Hailey explained.

"That's sounds really good, I'm certainly interested in doing that." Rojas replied. The two sitting around for a little longer talking.

"Watch out everyone, Detective Halstead is back. Be careful, he's fragile so if you touch him he might break." Platt joked as she saw Jay walk up the stairs into the district for the first time. Jay couldn't help but laugh.

"It's always good to see you sarge, thought you would back off the jokes but I was obviously wrong." Jay smiled back at Platt.

"I'm sorry detective, did I hurt your feelings. I see that Upton has turned you into a big softy." Platt continued, both of them laughing. "Seriously though Jay, it's really good to have you back, it hasn't been the same without you." Platt spoke.

"It's good to be back sarge, I'm ready to get back onto the streets." Jay replied. "I knew I was your favourite, I bet you missed me the most out of everyone you big softy." Jay chuckled as he fired a joke back at Platt as he started to walk upstairs.

"Get your ass up those stairs and out my sight detective." Platt fired back, Jay just laughing as he disappeared out of sight.

"Here he is, how you doing my guy." Ruzek greeted Jay as he came into view.

"I'm good man, it's good to be back." Jay spoke as the two shared a hug.

"Jay, my office." Hank grunted from the door of his office. Jay joined Hank in his office sitting opposite him.

"It's good to see you back up here, how you feeling?" Hank questioned.

"I'm feeling great, all healed up and passed for duty so I'm good to go." Jay replied.

"Well I'm going to put you on desk duty for this week, just to let you ease back into things."

"Ok that's fine." Jay agreed.

"One other thing, you need to get re-certified so make sure you head down to the shooting range." Hank explained.

"Before I go, I don't know if you heard but Mouse is back in Chicago and is planning to leave the army. So I was hoping that he could get his job back up here if that's good with you." Jay asked.

"Yeah he can come back that's no problem. To be honest I'm sick of Ruzek breaking all of the tech anyway so him being back will be good. Get him to drop by and sort out the paperwork with Platt." Voight replied.

"Thank you, I'll get him to drop by as soon as possible." Jay smiled back at the older man.

The two were interrupted by a serious looking superintendent Crawford, Jay excusing himself as Crawford demanded to speak to Hank alone.

Crawford exited his office a few minutes later closely followed by Hank, the rest of intelligence looking straight at Hank. "Right we've got a new case, there's been a string of robberies that started a few weeks ago on the south side. All of the victims of the robberies have been assaulted during the robbery but it escalated in the last robbery as the victim was found with 2 bullets to the chest." Hank explained.

"Why have we got this case and not robbery homicide?" Adam questioned.

"They been working it from the start but Crawford transferred it to us as they're 'fucking useless'. His words not mine." Hank continued, earning quiet chuckles from a few people.

"So what's the plan then boss?" Atwater spoke up.

"All of the robberies have targeted people coming back from Casinos so we have to presume they have an inside man so we need to flush him out. Hailey and Atwater you're going undercover into the casino and find the inside man. The rest of us will be waiting on the outside for your signal." Hank explained. He ordered the team to look through cameras and visit the victims hoping to get some information of the suspects.

"Hank I know you're not going to let me go undercover with Hailey but you have to let me be on the outside." Jay demanded as he followed Voight into his office.

"No." Hank responded bluntly.

"Voight please, Hailey is the only good thing that is going on in my life at the moment and if anything was to happen to her it would destroy me. Hailey is the person I love and Will is the only family I have left so if there's anything I can do to protect them I need to that." Jay was almost pleading as he begged Voight.

Hank contemplated Jay words for a moment before he spoke again. "Fine you can come but first you need to get to the shooting range. You're riding with me as well so at least I can hold you back." Voight replied. Jay agreeing and started to hastily head for the shooting range. "Jay one more thing." Jay turned back towards Voight. "Will is not your only family, everyone up here is your family as well, don't ever doubt that."

The case actually turned out to be pretty straight forward in the end. While undercover it didn't take Hailey and Kevin long to find the lookout. They spotted him carefully looking over the tables with a radio, clearly giving information to the robbery crew. As Hailey and Kev started to close in on him the lookout tried to escape he was quickly stopped by Ruzek who was covering one of the fire exits. When interrogated it quickly became clear that the young adult was pressured into this and was very nervous, so he quickly gave up the robbery crew when Voight offered him a deal.

The robbery crew consisted of 2 brothers, Shaun Phillips and his brother Jason. Shaun was the brains of the operation and was previously convicted of armed robbery and assault with a deadly weapon. He had threatened the young lookout's family if he didn't comply with his demands. His brother Jason was different to his brother, he had no priors and he was only the driver in these attacks, not once did he attack anyone.

The hardest part of the case was locating them, since being released from prison 5 months earlier, Shaun was a ghost. No social media presence, no traceable phone and his last known address was a dead end. They concentrated on Jason, when they looked into his communications they found many different interactions with burners phone, all of which now dead. They eventually got a warrant to access the GPS on his registered vehicle, everything seemed normally however there were 3 visits to an abandoned workshop close to the casino, which instantly raised suspicions.

The team geared up and headed to the workshop, as they entered they found the two brothers sorting through their profits from the robberies. They had the place surrounded and when they announced themselves Jason surrendered immediately. Shaun wasn't as cooperative though, he fired a few shots in the direction of the team and quickly made his escape towards the back entrance, he was quickly halted by Atwater and after a short tussle he was disarmed and arrested.

"Here's to the return of Halstead and Mouse, even though he isn't here." Shouted Ruzek as they all clinked there glasses together at Molly's after a successful first week back for Halstead.

"Thanks guys, it was good to be back in the field with everyone." Jay admitted. The atmosphere at Molly's was good, the bar was packed, there was a mixture of firehouse 51, district 21 and Chicago med at Molly's. Once again Jay and Hailey found themselves at a table with Kidd, Severide, Casey, Adam and Kim.

Hailey started teasing Jay again like she did at Casey's party, grinding her ass against Jay and rubbing Jay's inner thigh. "You're not doing this to me again." Jay whispered him her ear as he grabbed her hand, Hailey chuckling quietly.

"And what would that be." Hailey whispered as she turned to face him.

"Teasing me and making walk through a crowded bar with a hard on." Jay fired back.

"How are you going to stop me?" Hailey questioned as she rubbed her free hand against his crotch. A cheeky smile on her lips, Jay gasping from the touch of Hailey's hand.

"We are getting out of here right now." Jay replied, grabbing hold of her wrist and quickly headed for the exit.

The drive back to their apartment was absolute torture for Jay. Hailey's hands were once again on him, teasing him the whole way home. He tried so hard to concentrate on the road but he couldn't shift his focus away from the feeling of her hands. It was lucky that Hailey's apartment was only a 10 minute drive from Molly's otherwise he probably would have crashed his car.

They raced into Hailey's apartment, their clothes quickly forgotten about and they were left just in their underwear. Jay pinned Hailey against a wall, he was definitely taking control of this situation, their lips joined in a fiery kiss, both of them hungry for each other. Jay moved his attention to Hailey's neck, peppering her neck with light kisses.

Jay started sucking on her neck, soothing the area with his tongue afterwards. While he continued his movements on her neck he moved his hand down her body and he slowly started stroking her clit through her lace panties. Hailey releasing a soft moan from the touch of Jay's fingers. Jay's spare hand trailed slowly along Hailey's side and disappeared behind her back to undo her bra.

As he discarded her bra somewhere behind him he moved his lips and slowly sucked on her nipple, slowly tugged on her nipple with his teeth. "Jay please." Hailey pleaded as she got closer to her orgasm. However Jay had different ideas as he stopped his movements on her body, Hailey groaning in frustration. Jay laughing quietly as he picked her up and carried her up to their bedroom.

Jay placed her on the bed and quickly got rid of her lace panties. Before Hailey could comprehend what was happening Jay entered her with his tongue. "Oh my god." Hailey moaned as she started to grind her hips against Jay. Hailey's moans became louder and louder as Jay's tongue hit her in all the right places.

Hailey's movements became erratic the more Jay continued. Jay started stroking her clit with his fingers and that was the catalyst to push her over the edge. She let out a loud scream as her orgasm coursed through her body, her legs and hips shaking as Jay continued his movements prolonging her orgasm.

As Hailey started to come down from her high Jay thrusted two fingers inside of her, his fingers curling up to hit her G-spot. Hailey's moans were even more intense than before. "Hailey look at me baby." Jay demanded as he moved down to suck hard on her clit.

"Fuck Jay, don't stop, oh my god." Hailey exclaimed as she tried her best to keep eye contact with Jay. She threw her head back against the bed as Jay sucked hard on her clit and hit her G-spot in sync, another orgasm ripping through her body.

It took a few moments for Hailey's breathing to regulate and once she calmed down she was quickly tugging at Jay's underwear. "Off, Now!" Hailey demanded, Jay obeying.

Jay lined himself up with her entrance and swiftly thrusted into her. Jay's thrusts were fast and rough and Hailey grinned up into his movements. A mixture of loud moans and curse words left her mouth as her nails dug deep into his shoulder blades, definitely leaving red marks.

Jay brought one of his hands to her clit, furiously rubbing her bundle of nerves pushing her towards her release. The pleasure from Jay's movements was becoming too much to handle for Hailey. Her hands fell from Jay's shoulders as she lost control of her body as another orgasm hit her.

Her legs once again started shaking and as her walls tightened around Jay he quickly followed her, riding out his own orgasm as he let out a loud moan. Jay continuing his thrusts to prolong both of their orgasms. Once they both came down through their highs Hailey pulled Jay down for a passionate kiss.

After a few moments Jay settled down next to her. She rested her head on his chest as they cuddled up close, Jay wrapping his arms around her. "You have no idea how good that felt." Hailey whispered, a big smile on her face.

"Oh I have a pretty good idea." Jay chuckled as he rested his head on his pillow.

"Maybe I should tease you more if that's what you're going to do to me, I could get used to that." Hailey replied, testing Jay's response.

"No no no, if you leave me like that again I certainly won't be doing this again. However if you behave this can happen anytime you want." Jay fired back.

"That sounds like a deal I could go along with." Hailey chuckled.

"I love you so much." Jay softly spoke as he looked down at Hailey.

"I love you too." Hailey replied.
