Chapter 8

After Erin left, Jay carried the bed into the spare room. He began putting it together while thinking about how his life had drastically changed. Not only had Erin become more than his partner, he now had a little girl that depended on him for everything. He really didn't know how to raise a child, but he was going to do his damn best by her. He would make sure she was well loved and well taken care of. She was never gonna know the life some kids he worked with did.

He prayed Erin's conversation with Voight went well because if not, he didn't know what he would do. Intelligence had become his life and he needed the job more than ever. Erin had also become a major part of it, and if he had to transfer just to keep her, he would. She was worth it, and she would make a great mom to Jaylyn.

He kept working on the bed while listening for JayJay to wake up. It was going to take some time adjusting to having a little one around, but he would do it because he was all she had. He just hoped that while he adjusted, he didn't damage his little girl in the process. He would never forgive himself if Jaylyn suffered because he didn't know what he was doing.

Meanwhile across town, Erin arrived at the precinct. Platt greeted her with "I thought Voight said you and Halstead were off today?"

"We are, but I need to talk to him about something real quick. He's here right?"

Platt nodded as Erin ran up the stairs.

"Well there she is. What'd you do with Halstead, Lindsey? Bury him somewhere for us to find later?" Ruzek jokingly asked her. Erin flipped him off as she continued to Voight's office. She knocked but walked on in.

"Hey Erin. So I'm assuming you're here to tell me why you and Halstead both needed the day off?"

Erin shook her head no. "That's for Jay to tell you later. I'm here for a more personal talk." Voight nodded as she took a seat. "Hank you know how much I appreciate what you did for me and for taking me in as your own daughter." Voight nodded. "But Hank, I'm a grown ass woman and can make my own decisions about who I date and who I don't."

Hank knew this day would come one day, but that didn't mean he had to like it. He'd been looking out for Erin for a long time, and she was his daughter in every sense of the word but blood. "What are you getting at Erin?"

"I want to be with Jay as more than his partner, but you've scared him off. He needs me more than ever now; he needs all of us more than ever and whether you give your blessing or not, we are going to be together. I don't need your blessing to date in my personal life, but for work we do. I hope you give it because I would hate to have to transfer." She saw how shocked Voight was and decided to explain more. "Jay loves his job, as do I, but I will not let you transfer him because we are dating. If anyone transfers it'll be me."

"Erin, no! I will not let you transfer because you were a part of this team long before Halstead came along. I told him to keep it in his pants, and if he hasn't, he's gone. No question about it."

Before he could go any further, Erin stood up. "Let's get this one thing straight right now. Jay has kept it in his pants. We've never been anything more than partners. We haven't officially said we are dating because of you, so if you want to be a hard ass because you want to keep control in my life, I will go talk to Platt right now. I will request a transfer and you will not be able to do anything about it. Jay and I will be together. It's up to you whether we both stay with the team or if I leave."

She could see defeat in his eyes. She hated being like this with him, but she loved Jay and wanted to be with him. Hank sighed, "Keep it professional on the job, and I won't say a word. But I expect an explanation for today. Like tomorrow. From both of you."

Erin went around the desk and hugged him. "And you will, Hank. Halstead will you fill you in."

With that, Erin went out the door. Hank sat back and sighed. He knew teaching her to stand up for herself and fight for what she believed in would come back to bite him in the ass one day, but she was right. Halstead was a good guy and deep down he knew Jay would treat her like the princess she was.

Back at Jay's apartment, Jay had gotten the bed completely together when he heard Jaylyn start to whimper. Luckily he was just in the kitchen looking over the papers Emmalyn left so he got to her pretty quickly. "Hi princess. Did you sleep good?"

Jaylyn sorta nodded and lifted her arms up toward him. Jay picked her up and sat down on the couch with her. Jaylyn laid her head on his shoulder. "Where mommy?"

Jay knew this would happen, but how do you tell a two year old that mommy was gone for good? "She had to work, baby. You're going to be staying with daddy from now on." Jaylyn nodded with tears in her eyes. "Mommy gone?" Jay wrapped his arms around her tightly. "Yes, baby. But daddy is going to take really good care of you, and love you every day." Jaylyn nodded as she laid her head on his shoulder once more.

"Hey JayJay, how would you like to see where daddy works and meet the people he works with tomorrow?" Jaylyn lifted her head and looked at him. "Reawwy?" "Yea. Daddy and Erin will take you. Erin works with daddy too, and everyone daddy works with will love you too JayJay."

Jaylyn snuggled closer to her daddy. "Wuv you dada."

"I love you too princess. Do you want to see your new room?" Jaylyn jumped up. "Come on, daddy put your bed together while you slept." Jay and Jaylyn went to the spare room which would now be Jaylyn's. Jaylyn just stood there looking at her bed. "Daddy's going to get you a dresser to put all your clothes in and a toy box for all your toys. Would Jaylyn like some princess sheets to sleep on?" Jaylyn nodded. "JayJay a pwincess?"

"Yes, baby, you are. You are daddy's little princess. Come on JayJay. Let's go get your bags and bring them in here." Jaylyn followed Jay to the living room. Erin had been gone for three hours now, and he was beginning to think she wasn't coming back.

"Dada I hungwy."

"Ok well let's go see what we have to eat." Once in the kitchen, Jay picked Jaylyn up and set her on the bar. "I need you to sit really still ok?" Jaylyn nodded. Jay turned to look in the refrigerator. "Let's see; do you like grilled cheese sandwiches?"

"Uh huh."

"Ok so how about daddy fixes us a grilled cheese sandwiches while you go play in the living room."

"Otay" Jay set Jaylyn down and she took off for the living room. He got the stuff out and set it by the stove. Just as he got started cooking, he heard the front door open. He took off for the living room because he realized he never locked the door after Erin left. To his relief, he saw Erin coming through the door with several bags on her arms.

"What's all this?" he asked.

"Well I made a quick pit stop at the children's store on my way back. I thought a few toys, new sheets and bedding, and a few new clothes would make someone's day," Erin said smiling from ear to ear.

"Er, I'll pay you back for all of this, really."

"You will do no such thing Jay Halstead. This is my treat for the little princess." Hearing the word princess, Jaylyn came out from around the couch. "Pwincess? That's me." Erin and Jay both laughed. "That's right baby girl. You are daddy's princess," Jay said as he scooped her up.

"What do you say to Erin for all this stuff?"

"Fank you Ewin."

"You're welcome baby. JayJay, would you like to help me fix up your bed? I think I smell your daddy trying to cook." Jay immediately set Jaylyn down and ran back to the kitchen. He had totally forgotten he had started the grilled cheeses. At least he liked his a little well done. Jay could hear the girls the giggling from the bedroom. Once he had the sandwiches done, he went to Jaylyn's room.

He stood in the doorway just watching them. The bed was made up with Cinderella sheets and the comforter had all the different princess on it. Erin had unpacked the toy bags and was sitting on the floor playing with Jaylyn who was dressed up like a princess.

"Ewin, do you wuv my dada?" Leave it to his daughter to ask the tough questions first; he was anxious to see where this conversation went though.

"Yes, JayJay I do."

"Does that mean you be my mommy now?"

"Ummm.. I don't know JayJay. That'll be up to your daddy. Even if I'm not your mommy, I'll always be here for you. you can always come to me for anything."

"I wuv you Ewin."

"I love you too JayJay."

Erin wrapped Jaylyn in a hug and that's when she noticed jay standing in the doorway. "I think daddy has lunch ready pretty girl."

"Dada" Jaylyn said as she ran to her daddy. "Hey, baby, you ready to eat?" Jaylyn nodded. "Dada, Ewins nice."

"I think so too JayJay. Come on let's go eat." Jay set Jaylyn in her high chair while he and Erin ate at the bar. While they were eating, Erin looked over Jaylyn's schedule and saw she was due a nap in an hour. Erin wondered if she would sleep since she slept so much that morning.

"How'd it go with Voight?" Jay asked bringing Erin out of her thoughts.

"Oh, um, it went good. He said to keep it professional on the job and he wouldn't say anything. Oh, and he wants an explanation for today, and I told him you would explain tomorrow." Jay was shocked to say the least.

"Voight really said it was okay for us to date?"

"Sure did. Don't look so surprised Halstead. You knew I would handle him." Jay just laughed.

"Dada!"

"Yes, baby?"

"I done."

"Okay. Do you want to go watch some TV?"

Jaylyn nodded. "I think someone is still sleepy," Erin whispered to Jay as she nodded toward the schedule. Jay nodded as he got up to get Jaylyn out. "Go watch TV with her and I'll clean up and then join you."

Jay carried Jaylyn into the living room and set down on the couch with her. Mickey Mouse was on. Jaylyn laid her head in Jay's lap. Within the hour, she was asleep. Erin walked in and picked her up. They carried her to her room and tucked her in. Jay kissed her on top of the head and followed Erin out. They left her door open so they could hear her when she awoke.

Erin snuggled into Jay on the couch. "Halstead, you are pretty amazing."

"So are you Er." He leaned down to kiss her, and she straddled his lap. "Er, what are you doing?"

"I'm making out with you," she said with a grin.

"I can see that, but what happened to a date first?"

"Plans change. I realized today that I've always loved you and that is not going to change by going on a first date. I saw you with Jaylyn today, and how amazing you are with her. It showed me that I want this, all of this, with you."

Jay wrapped his arms around her; picked her up, and carried her to the bedroom. "What about Jaylyn?" he asked.

"She's asleep Jay. We'll hear her if she wakes.

"Can you be quiet?" he asked with a chuckle.

"Of course, Jay Halstead!"

He'd stripped her of her clothes before he laid her down on the bed. "You're so perfect Erin, so beautiful." Jay began kissing down her chest. "mmm so perfect," he said as he pulled her bra off. He kissed around each breast being careful not to touch her nipples. Erin was moaning at his teasing.

"Remember you gotta be quiet," he said as he blew cool air across each nipple. He watched as they got harder. "MMM, Jay, please," Erin begged. He circled one nipple and then the other before taking the first one between his lips. He put his hand over her mouth to keep her from screaming out. He repeated the same motions on her other nipple. He could feel her bucking against him.

Erin reached down to strip him. Once she had his pants off, she patted the bed beside her. Jay just shook his head; "Oh, no, missy, this is all about you." Before he got "you" all the way out, Erin flipped them so she was now straddling him. Jay could feel her wetness through their underwear. "Erin, baby, I was really trying to make this all about you, make it special this first time."

"I know, but I don't do slow," she said with a wink. She shimmied out of her panties right before she pulled his boxers off. Jay flipped them back over and kissed down her perfectly toned stomach. He ran his finger down between her legs. He knew she was wet, but he wanted to see how wet.

He brushed his finger down over her clit and spread her wetness all around. "Jay, please," Erin begged. She reached down and grabbed him, trying to guide him in her. He stopped right before he pushed in; "Erin, I love you so much." Right as he started pushing in, he stopped. Erin had a confused look on her face as he started to roll off of her. "Jay, what's wrong?" she asked fearing she had done something wrong.

He reached for the bedside table pulling out a condom. "Jay, I'm on the pill; we don't need that." Jay sighed as he rolled back on top of her. "Sorry for scaring you," he whispered. He ran his finger back down through her wetness. "Jay, please, just fuck me," Erin begged.

Jay kissed her on the lips. "You are so perfect," he said as he pushed all the way in. "MMMM Jay," she moaned. Jay started out moving slowly; in and out, in and out. She was so tight and so wet. He felt like a teenager all over again because he didn't know how long he was going to last.

"Faster, Jay, faster," Erin pleaded. Jay moved faster and faster still. Erin wrapped her legs around him, just making her that much tighter around him. Erin could feel Jay's control starting to slip as he got faster and harder. She ran her fingers through his hair and said the words she knew would make him snap; "Make me come Jay. Make me come with you."

That's all it took for Jay to lose control. He was thrusting wildly into her but she was keeping up. He angled his hips to hit her g-spot over and over. He could feel her tightening around him. "Come for me, baby, come," Jay whispered into her ear. He felt her muscles contract and he kissed her lips to swallow her cries as he came with her.

He was careful not to crush her when they were done. He rolled over onto his side and pulled her with him. "Erin, you are mine forever," he said as he kissed her on the lips.

"There's no place I'd rather be," she whispered. They stay snuggled together until Jay heard Jaylyn starting to stir almost two hours later. They were definitely going to invest in a baby monitor that week.

A/N: So there is chapter 8. This chapter kinda got away from me and I just couldn't quit writing. I was desperate for some Linstead sexy time, so I just had to write it. I know there wasn't much parenting, but that is coming I promise. I just wanted to get Erin and Jay into an established relationship. I hope you liked this update, and the next chapter should be out soon. School is winding down, so I should be able to write more. As usual let me know what you think .

Up Next: Jay faces Hank and admits the truth about Jaylyn.
