It took several hours to finish up the pile up scene. The drive back to 51 was very quiet. Everyone was exhausted.

The trucks pulled onto the apparatus floor. Everyone jumped out and stripped off their bunker gear. They all headed inside to the kitchen to find some form of food.

Shelby was getting a bottle of water from the fridge when Kelly approached her.

"My office Jensen." With that Kelly turned around and headed to his office. Shelby rolled her eyes. She sat the water on the counter and followed Kelly to his office.

He waited for her to enter and then he closed the door behind them. Kelly then closed the blinds in his office before he started to yell at her. "What the hell was that back there?!"

"I was saving a guys life." Shelby crossed her arms and glared at Kelly.

"While risking your own!? You know we could of been pulling you and that victim out had something gone wrong!"

"But it didn't! The driver and me are both fine!" Shelby wasn't going to put up with Kelly's shit. "You and me are the same rank Severide! I know how to do my job!"

Kelly stepped forward so they were inches from each other. "But you are in MY house and on MY squad!"

Shelby could feel Kelly's hot breath on her face. "It's not like I had a choice! It was either this or sit next to Adam all damn day." The two of them are furious with rage.

"I am not going to lose another friend Jensen!" Kelly lowered his voice."I can't lose you. I've already lost Andy, Angie, and Hallie." Kellys eyes had soften. He didn't like yelling at her but he felt like he had too.

Shelby stood there shocked. "Kel we don't even know each other anymore."

"Doesn't mean your not my friend." Shelby swallowed the lump in her throat. How could he still care? After everything that had happened that spring break. Kelly then wrapped her in a tight gripping hug. He whispered in her ear "I can't lose you."

Shelby wrapped her arms around Kelly and returned his hug. "You won't."

After a minute of standing there in each other's arms Kelly pulls back just enough so he can look her in the eyes and keeping his arms wrapped around her waist. "Just please be careful."

Shelby rests her forehead against Kelly's. "I will."

They were both so close to one another. There felt like there was this force pulling them closer together. Kelly went in for a kiss but hesitated for a second to see if she would move.

When she didn't Kelly took that as another sign. He captured her lips with his. The heart fluttering came back. It felt like the very first time they kissed as teenagers. Shelby had her arms wrapped around Kelly's neck while his hands rested on her waist.

Kelly backed her up against the wall in his office. Pinning her there. Never breaking the kiss. Kelly pressed against her and it sent her body into overdrive. Shelby moaned.

This gave Kelly so much desire. Kelly placed his hands underneath her butt and pulled upwards. Shelby jumped and wrapped her legs around his waist.

Kelly then moved them over to his bed and gently laid her down. He quickly locked the door. He kicked off his shoes and climbed on top of Shelby. Hovering just over top of her.

Shelby pulled at the hem of his shirt and helped him take it off. Kelly removed her shirt before their lips reconnected. Another hot lust filled make out session began.

Kelly moved his mouth from her lips to her jawline and then trailed kiss to her pulse point on her neck. When he began to nibble and suck it sent shivers down her body. She thrusted her hips up into Kelly's.

Kelly's head came back up and he let out a moan when he felt her press against him. Kelly snaked a hand behind her back and unclasped her bra and tossed it to the side.

Kelly then began his attack on her breast. Sucking and biting each nipple. While his hand played with the one that wasn't in his mouth.

"Kelllyyy." Shelby moaned his name. The pleasure coursing through her body was becoming overwhelming.

Kelly came back up to her lips and just hovered slightly above them. "Do you want me?" Shelby bit her lip and nodded her head. Kelly lowered his lips down to her ear. "Say it."

Kelly's breath sent another wave of shivers down her spine. "I want you Kelly." Kelly's eyes went dark with lust. He then relieved her of her pants and panties.

He then stripped of his own pants and boxers. Kelly climbed back on top of her. Shelby could feel him pressing against her inner thigh. She thrusted her hips up into Kelly.

Kelly captured her lips for another kiss and just as their lips parted he thrusted in side her. Shelby instantly gasp. Her hands began clawing at Kelly's back.

Kelly began to thrust in and out of her. Their bodies soon form a rhythm together. It still felt just as amazing as it did when they were teenagers. Kelly picked up his pace. They were both reaching their peaks.

Shelby began to rock her hips up into Kelly's. Within a few more thrust Shelby and Kelly were both falling over the edge. Kelly collapsed down next to her. Their sweaty bodies clinging to one another. Both of them out of breath.

"That was amazing." Kelly placed a kiss to her cheek. Shelby just nodded her head still trying to catch her breath. Kelly wrapped an arm around her waist and held her close.

After they both finally caught their breath. Shelby sat up and began to gather her clothes.

Kelly propped himself up on his elbows. "Where are you going?"

"To take a shower. Plus people are going to wonder where we are." Shelby began to get dress.

"Fair enough." Kelly got up and got dressed as well. They both then exited Kelly's office. Shelby headed for the showers while Kelly headed for the squad table.
