Wow, I'm thrilled to have got such an amazing response to this story. So I busted my butt to have a second chapter done today. This weekend I am celebrating my twentieth birthday, so I won't be able to write anything, as I'll be partying tonight and probably be hungover on sunday haha. Alright enough talking, enjoy !

He was fidgeting. Kelly Severide never fidgeted. But now, he was nervous out of his mind. Here he was, standing in front of Erin Lindsay's door, unable to sum up the courage to actually knock. They had kissed. They had slept together.

But he didn't do dates. To him, dates were awkward dinners where you made small talks to a person you barely knew.

Taking a deep breath, he raised his fist to the door and knocked. He heard heels walking on hardwood floors and he could hear his own heart beat in his ears.

After what seemed an eternity, Erin finally opened the door.

Holy shit.

There she was, standing in front of him in skinny jeans tucked into boots, a green top that made her eyes stand out, light make-up -not too much, because she didn't need it if you asked him- and pearl earrings. In a nut-shell, she looked sexy as hell.

"Um...hi," he managed to croak out, unable to shift his eyes away from her body.

"Hi. You know, my eyes are up here."

Oh, right.

His eyes snapped up to meet hers. "Sorry. You just look... stunning."

She smiled and crossed the threshold, closing the door behind her. "You don't look too bad yourself, Lieutenant."

He was wearing a simple grey shirt, black jeans, boots and his usual back leather jacket. His blue eyes stood out and she could feel herself swoon under his gaze.

"You ready?"

She nodded. "Lead the way,"

She was glad when she realized he had taken her to a steakhouse and not a fancy restaurant. She didn't like fancy restaurants that much. What's the deal with paying a dinner an arm and getting barely enough food to be satisfied afterwards?

She figured Severide had the same point of view since he ordered a 32 oz steak. The date went by so fast, too fast for Kelly's taste. He couldn't get enough of her. Enough of her laugh, her smile, her eyes. He was hooked, and already thinking about when the next date would be.

Once he had paid for dinner -after a heated argument with his date about who should pay-, they walked out of the restaurant and into the street.

"Do you feel like having a beer at Molly's or do you want me to walk you back home?" he asked her.

She smiled. "Well the night is only started. A beer at Molly's if fine by me, even though it means us coming out to your colleagues."

"Ouch," he teased. "Are you ashamed of me, detective?" He asked as they started walking down the street.

She raised an eyebrow and hissed. "I don't know, I think your colleagues love me more than you, I wouldn't want to disappoint them."

"Haha, aren't you full of yourself."

She acted surprised. "Me? Never. And no, I don't have a problem with us going public, Kelly."

He smiled and looked at her. "So are we dating now?"

Erin laughed. "Are you a sixteen-year-old that needs to put labels on everything, Severide?" She swore he was blushing. She stopped walking and turned to him, slipping her arms around his neck. "Well yeah, I guess I'm your girlfriend then."

He leaned down to kiss her sweetly and smiled. "You're right, I actually feel like I'm a teenager. I don't care, I got a girlfriend." He fist pumped, which made her roll her eyes and push him away.

They started walking again, and she slipped her arm through his, hugging his side. She had never been a PDA kind of girl, and she even less felt the need to have a man around her. But with Kelly, it was different, he seemed to genuinely like her, and to be honest and sweet. Her walls were slowly starting to be put down and it felt right, why couldn't she be happy for once?

When they arrived at Molly's, the place was crowded. The whole firehouse was there, with the exception of Chief Boden. Their entrance wasn't unnoticed by a few people and Erin blushed when she caught Shay's amused eyes.

"Good to see you Dawson," Severide said as soon as he saw her, giving her a brief hug.

"Thanks Severide, I'm glad to be here," Gabby's eyes moved to Erin. "Hey Lindsay."

Erin waved and suddenly felt shy. Severide got them two beers and went to sat at the same table as Shay and Clarke.

"Look who's healed and already drinkin' beer," Severide cheered before hugging Shay. He then shook Clarke's hand. As Lindsay and Clarke started to talk about god knows what, Severide leaned over to Shay. "So, where's Rafferty?"

A deep blush made its way onto Shay's cheeks and she took a long swing of her beer. "Don't start, Kelly. Nothing to say."

"You should ask her out on a date," he said. Shay looked at him with wide eyes. "What? Man up. I did," he said with a smile on his face, his eyes drifting toward Lindsay who wasn't paying attention. "Look where it got me."

As if destiny had decided to play a trick on Shay, Rafferty walked into the bar as Severide spoke the words. Shay excused herself and Severide laughed, shaking his head at her. Clarke called it a night soon after and Severide realized that he was alone at the table, as Lindsay had suddenly made besties with Dawson at the counter. He sighed and nursed his beer, thinking about how he got so lucky.

After a while, he walked back to her and slipped his arm around her waist, whispering into her ear.

"Wanna get out of here?" A chill ran down her spine at the sound of his voice. She nodded, and grabbed his hand, leading him out of the bar.

Once they had gotten back to her apartment, it wasn't long before clothes started flying everywhere. The tenderness from the night before was long abandoned, and it was replaced by eagerness and passion.

Severide closed the door behind them, pressing her against it as he cupped her cheeks and pulled her into a heated kiss. She ran her fingers through his hair and ran her hands down to his chest, starting to undo the buttons of his shirt.

He pulled away and smirked. "Eager much?"

Erin silenced him with a hot kiss. "Shut up."

"Your wish is my command," Shrugging his now unbuttoned shirt from his shoulders, he then wrapped his arms around her waist and easily picked her up. Circling his waist with her legs she bent down and kissed him as he carried her to the bedroom.

He laid her down on the bed, his mouth leaving her lips to explore down her neck. He felt her fingers working on his belt and stopped her movements.

"How come I'm almost naked and you're fully dressed. That's not fair, detective."

She cocked an eyebrow, a smirk on her lips. "Well you should do something about that, Severide."

He chuckled and pulled her top over her head, leaving her in a black bra. Things got gentler after that, as they took the time to drink in each other's body. The remaining of their clothes joined the rest on the floor, and Erin suddenly felt self conscious when his eyes racked over her naked body. It was nothing he hadn't seen before, but the other night she felt as if she was elsewhere, wanting him to make her forget about the day's previous event.

He seemed to realize she was uncomfortable and stroke her cheek. "You're beautiful."

Erin lifted her head and kissed him, bringing his lips down onto hers. Then, it was kind of a blur. His name escaped her parted lips as he made love to her, bringing both of them to the edge.

Afterwards, he pulled her to his side and kissed her hair, before sleep took them both over. A few hours later, when he woke up, she was putting her boots on, fully dressed, and he gave her a confused look.

"Hey," she said as she walked to the bed.

He looked at the clock which indicated 3 am. "Walking out on me?" He joked, because they were actually in her apartment.

She smirked. "Yeah, cause you were that bad. Voight called me, we have a suspect on that drug dealer we've been trying to catch for days. It was kinda put on hold after the explosion, but we got news. I gotta go."

"No worries." He looked her up and down and she looked so sexy with her glock strapped to her waist. He wasn't a fan of weapons, but it looked hot on his girl. "I'm on shift tonight 'till Friday night. I guess we won't see much of each other the next couple of days."

"I guess so. I'll see you later then." She leaned in to give him a light kiss and squealed when he grabbed her by the waist and rolled her underneath him. "Kelly! I need to get to work."

"You're so damn sexy," he whispered, capturing her lips once more. She moaned and slipped her hands around his neck. There was a round of heated kisses before Lindsay came to her senses.

"I have to go."

He pulled away. "Right, sorry."

"No you're not," she laughed.

He looked at her sheepishly. "You're right, I'm not."

Erin stood up and adjusted her belt before running a hand through her hair. "Stay here, just shut the door when you leave."

"Sure thing, detective."

She gave him a seductive smile when she got to the doorway. "See ya later, Lieutenant."
