"She's going to know I was here." Jay whispered as his lips hovered over Erin's for a few moments. His hands wrapped firmly around her hips, a hand rubbing up and down her side every so often.

She chuckled, pulling out of his hold as she continued to place some clean cups on the counter, ready for the kettle to boil.

Lowering her tone quickly as she realised that Sara would be waking up to head for college soon, or rather should be. "Shh" She giggled softly. "Trust me. She'll know."

Raising his eyebrow and leaning his back against one of the other counters, he scoffed. "How?"

"Because I'm not 8 anymore, Jay!" A voice groaned from behind the corner. It was Sara, tying up her long brown locks into a no nonsense bun she grimaced at the sight in front of her. She wished Jay would just move in already, it would make waking up in the morning a lot less painful, especially if she didn't have to listen to her mom and her somewhat boyfriend giggle like school yard teenagers. Although she could debate that that would most likely not stop.

"Told ya." Erin smirked as she continued to make the coffee. She looked up briefly and watched her daughter and Jay interact.

Jay poked her stomach as Sara fixed her hair making her leap backwards using her feet to kick the detectives hands away. "Jay stop it."

"Oh you used to love getting all the attention." He chucked.

"Yes. When mom and you were stuck at the precinct with those cases that took forever to solve. I liked it then when it was either be looked after by Hank and bored outta my mind." She countered. "Anyways. I fight back now." She added at the end with a slight smirk.

Sara at seventeen years old was a Senior in Park High, athletically talented as Captain of the Cheer Squad. She was studying to become a doctor, an ambition she had since a young age.

"Morning mom." Sara smiled as she placed a kiss on her mother's cheek as she finally moved from Jay's reach. Moving around her mom she reached for a coffee cup and placed it beside Jay's signalling her want for coffee.

"You okay, honey?" Erin looked up with a smile on her face. "Oh. Your dad called? Know anything about that?"

Offering the two cups of coffee to Jay and her daughter, she waited for Sara's explanation expectedly.

Erin was only 18 when she had Sara with Andy Clements, she was on her way to the straight and narrow when she decided to attend a college party. Instead of getting completely hammered like she had intended on doing she met someone, Andy. Andy was in his first year of college studying to become a lawyer when they found out that they were expecting, the two teenagers hadn't had a clue what to do.

Andy was still in Sara's life, he was living in the 'uptight' part of town as Jay would refer to it as. Sara could've easily chosen to live with her dad but she decided against it, after all Sara's bond with her mom was practically unbreakable.

"What from that dic-"

"Sara!" Erin warned, her head snapping towards her daughter. As much as Erin hated Andy sometimes she would never allow her daughter to disrespect someone.

Jay spat the coffee he had just drank back into the cup as he sniggered. "She's got a point, Er."

"You. Stop encouraging her." Erin pointed her finger in Jay's direction, a glare to go with it before directing her gaze to her daughter. "And you, call your dad back."

"Mom." Sara whined.

"I'm not telling you again. Now how are you getting to school?" Erin asked, lifting the piece of toast she had just buttered to her mouth.

"Jay's taking me." She said simply. As she bit a little piece of her mother's toast.

Erin rolled her eyes and swatted her hand away. "And does Jay know this?"

"Jay?" Sara smiled sweetly at the man she considered a father figure.

Since her mom started with the Intelligence unit Sara had became part of the furniture as some would say. She was close to everyone, namely Antonio, considering he and her mom got on really well. But as time seemed to pass her mom got closer and closer to Jay Halstead, Sara didn't mind, Jay treated her kindly, different to some of the other officers. He acted like her Dad and she was pretty damn sure he'd be the first there if she needed anything.

"It's fine, Er. I can take her." Jay reassured. Finishing the coffee he had, he set the mug in the sink before leaning over the open planned counter, his lips latching to Erin's.

"Ew. Ew. Ew. That burns. Stop it." Sara feigned gagging sounds as she waited for the two adults to separate. She realised they were now continuing to spite her as her mom ran a hand across Jay's hair. "Sweet and innocent child over here."

"I didn't hear anyone come in." Jay mocked as he looked around the apartment. Watching Sara's face drop he couldn't help but let out a chuckle. Letting go of Erin he shrugged on his jacket before leaning over to ruffle Sara's hair, making her groan in annoyance. "Love ya really, kid. Come on, we're gonna be late."

"See ya later babe." Erin called as she heard the door slam shut behind the pair.

Finally, she was left in some piece to get ready for work.

"When are you and mom gonna stop tip toeing around me?" Sara asked Jay as they made their way down the stairs.

"What do you mean?" He asked. He looked back at the girl who was quite far behind him. "You struggling back there?" He chuckled.

"Jay...You do it and you don't even realise it." She whined. Letting out a huff as she continued to catch up. "Well, not all of us feel the need to run up flights of stairs for fun. Could 'a just taken the lift." She grumbled, adjusting the strap on her bag.

"Where's the fun in that?" He let out a little laugh. Opening the door, leading Sara out first.

"You're not like him Jay." When Jay looked at her uncertainly she elaborated. "Dad."

Sara loved her Dad, he supported her, although it was mostly financially it did mean her mom didn't have to struggle for the money. It's not like she would now, she could manage but when Sara was small and Erin willed for everything not to ask Hank for help, again, Andy's help was really appreciated. Sara would spend weekends with her Dad almost twice a month and sometimes even more but when Sara started High School she had began to drift away from that and her opinions had of course been impaired by what people thought of him too.

"You make mom happy. I don't want to take that away." He couldn't help but smirk slightly at the subtle challenge in his girlfriend's daughter's voice. "When are you gonna ask her to move in anyways?" Sara asked from her spot next to Jay as followed him to his parked car.

Jay stood dumbfounded unsure of how the girl he had known since she was 8 years old act so maturely. Granted, she was 17 now but he had watched her grow up into her teenage years but it still seized to amaze him.

"You kn- just get in" Jay ordered before the conversation went any further.

After dropping off Sara, Jay made his way to the precinct. Greeting officers, detectives and even sending a nod in Platt's direction he buzzed himself up to the bullpen, heading up.

"Did she get to school alright?" Erin checked as soon as she saw Jay walk up the stairs.

Although Sara was in her final year of High School that didn't stop Erin worrying about her only daughter.

Jay nodded mutely, a small smile playing on his lips as he noticed the pure love and devotion Erin had for her daughter. It was there constantly and it never left. He just hoped he could be a bigger part of that one day.

"Right. We've got a case."

Thank you for reading! Wow, so I'm kind nervous to post this one. This is a little different. I'm hoping this fic will be based more on audience participation rather than me hoping for the best! So reviews are appreciated! Thank you again.
