Rated M

It's Saturday again and Kelly Severide hasn't seen Lindsay in a week. It was driving him crazy. Sure they send texts every once in a while; he wasn't exactly sure where they were at but he definitely knew where he wished they were. It's been a week since he's seen 'his girl' and two weeks since their lips have touched and he couldn't handle it. He needed someone. He needed her. Sure the old Kelly would go off to a bar one night and bring home a random girl but after meeting Erin he didn't want just any girl in his bed, he wanted that girl.

When am I going to see you again? Kelly sent a text to Erin.

Blackhawks game is on TV tonight, come over and watch? Shay won't be home tonight, she's at Molly's. He sent another.

Erin smiled when she saw Kelly's name appear on her phone and opened the message.

Don't need to bring her home again? Erin let a slight laugh at her self, only joking around.

Nah, she's on her own tonight.

I'm in, want me to bring some pizza?

Sure, I'll see you tonight.

Kelly was smiling like a little school boy, excited to finally see this girl again. Erin was happy too, she knew what he was playing at when he said 'Shay won't be home' and she was definitely in.


Erin came knocking on Kelly's door at about 8:30, the Blackhawks vs. Senators game started at 9. Erin set down with the pizza on the couch and Kelly came over with beer and plates. "Oh perfect." She said grabbing a beer from his hands, he smiled. He liked a girl that knew her sports and drank beer. And after tonight, he liked that she could eat too, that girl ate half the pizza.

"YES!" Erin got up and cheered after the Blackhawks scored again putting them in the lead, they were just sitting at 2-2 for way too long for either of their liking.

As she set back down she noticed Kelly looking at her, "What?" She smirked.

"Nothing." Kelly huffed and they just stared at each other for a bit, slowly inching closer until their lips captured each others. Kelly laid her back on the couch, his tongue demanding entrance and Erin allowing it. No clothes were shed, only kissing.

Shay entered the apartment, neither noticing, both enjoying the moment. They didn't look up until Shay announced "Oh, ew. Get a room." As she walked past the couch.

The two stopped and let out a laugh, "Aren't you supposed to be at Molly's?" Kelly asked looking up at Shay.

"Yeah well I left, now regretting it. I'll be in my room, try and keep it down would ya?"

"Oh like you always do?" Kelly joked. Shay walked away and Kelly looked back down at Erin, still on top of her.

Erin stared back for a moment and then whispered, "Take me upstairs."

Kelly jumped up, grabbed Erin's hand and raced up to his room.

"Shh, Shay's going to hear us." Erin laughed, reminding him on his way up, as he pounded on the stairs.

"Oh I plan on making you scream louder tonight than ever before." Kelly smirked at her. Erin smirked back, she was intrigued and knew Kelly and Shay's banter was really a joke, Shay didn't care at all.

Kelly placed Erin on the bed gently, ripped off his shirt, then got on top of her, kissing her on the lips. He took a break to take off her shirt, and then quickly went back to the kissing.

As he began kissing her neck she grabbed his biceps and then started rubbing his chest. Slowly she reached her hands down to his pants, she could feel that he was hard.

He started kissing down her stomach, stopping at her waist line. She arched her back wanting more but instead of going any further he took that opportunity to unclip her bra. He then started trailing back up her stomach kissing her neck and playing with her breast, she couldn't hold it anymore, she started moaning.

He started unclipping her pants while trailing kisses back down her stomach. By time he reached her waistline they were off.

"Kelly" she let out as she spread her legs wanting more and he gave her head. But that wasn't enough. She let out a "more" between moans and he obliged. Taking off his pants quickly and going inside her. He couldn't handle the teasing anymore either. He started slow, it felt good and he knew it was still torcher to her.

She was already soaking wet so he knew it wouldn't be long until she was done. He wanted to make sure she was satisfied before him. He started going in and out faster, Erin let out a scream as she gripped the bed sheets tighter.

Kelly pulled himself out and rolled over onto his back, both breathing heavy.

"Wow." Erin let out between breaths. That was some of the best sex she has ever had, to say the least. It was passionate and he was gentle but rough at the same time.

"Yeah." Kelly was smirking.

They set in a comfortable silence for awhile, it was early morning but neither were tired. Erin had her head resting on Kelly's chest, playing with her fingers while Kelly was rubbing her back and arm slowly.

Erin decided to speak up first, "What are we doing, Kelly?" She took a breath. "I told myself I was taking things slow with you, but here we are in bed again and I've told you more about my life than I probably anyone else, at least not as quickly as I have told you. I'm fine with just sex, I don't know how to do relationships, but I need to know if you're playing womanizer or if we are supposed to be something." She finally shut up then, she didn't realize how much she was blabbering when it was just a simple question really.

"I like you Erin." Kelly said then and Erin looked up. "After the first night with you, I haven't wanted anyone else in my bed. I've told you before, I became that womanizer because I didn't want to get hurt again. But you're one of the ones that has me willing to try, if you want."

"I won't hurt you." She said while moving her head back down. She didn't know if that was true, Voight always told her she was the heartbreaker but she knew Kelly was a good guy and she didn't want to be that girl.

"We can start slow, maybe not high school slow since sex is already in the cards." Kelly joked and they both laughed. "But I can keep the PDA down, we can tell who you want, whatever you want."

"Oh, sex is definitely on the table." Erin joked back. "Thank you." And they fell back into silence until they fell asleep for the night.


Kelly was laying on his back and Erin was on the edge of the bed facing away from him, wrapped in almost all of the blankets. The two woke to a pounding on his door.

"Cover up, I'm coming in!" Shay's voiced yelled.

As Kelly came back to reality he scrounged up the blankets Erin seemed to be hogging. He knew Shay wasn't kidding and about to enter at any second.

She came walking in as Erin rolled over rubbing her eyes, looking confused.

"Look at this text Devin just sent me!" Shay let out pissed, shoving her phone in Kelly's face.

"Shay! Seriously?" Kelly let out a little frustrated. "Isn't there something in a known roommate contract saying no drama until awake and fully functioning? Not to mention dressed?"

"I am fully functioning and dressed." Shay stated the obvious.

Kelly grabbed the pillow from behind him and chucked it at her, he knew that she knew exactly what he meant. "Get out. I'll be downstairs in a minute." Shay exited the room.

Kelly let out a sigh and rubbed his hands over his face. When he looked to Erin she was already looking back at him, snuggled with the blankets.

"Next time we do this at my place." She spoke lightly.

"Agreed." Kelly smiled and pulled Erin in close, kissing the top of her head.

A few moments later he got out of bed sliding on his boxers and heading towards the door to talk to Shay real quick. "And we need to work on you taking all the blankets to the opposite side of the bed." He slipped in before exiting the room.

Okay wow. I never thought I'd be writing something like this but some how I did it. Hey, you guys said you wanted sexy time, so here it is.
I wanted to put more than sex into this chapter but I wasn't really sure what else to do. The only thing I had in my mind was Shay entering in the morning but I couldn't come up with a good reason why, so hopefully this wasn't too stupid.
Please review. I love getting ideas from you guys.
