A/N: Because I have long shipped Roman and Burgess. Ruzek was never good enough for her. Takes place immediately after Burgess kissed Roman in S3:E19.
Kim Burgess had no idea what had gotten into her. Kissing her partner, in the station no less, was the most outrageous thing she had ever done.
She avoided him for the remainder of the shift, keeping herself busy wherever Sean Roman wasn't.
Her problem was she couldn't stop thinking about the kiss and found herself touching her lips repeatedly.
Stop it, she chastised herself. This was ridiculous! She palmed her forehead.
Kim looked around to see if anyone had noticed her erratic behavior.
Glancing at the clock, she realized her shift had ended and she nearly ran to her locker.
She swiftly changed and was shutting her locker when Sean materialized at her side. Before she could escape, he caged her between his solid chest and the lockers, and without pretense, he captured her mouth with his in a hungry kiss.
Kim grasped his uniform shirt in surprise but didn't push him away. She allowed herself to meld into his embrace.
When Sean came up for air, he pressed his forehead on hers.
"Come over tonight," he huskily whispered.
She nodded, not trusting herself to speak. He released her and she slipped out of the room.
Kim drove around for a while, trying to decide if she should go or not. She wanted this but felt conflicted. In the end, she ended up at his place.
She knocked on Sean's door and he answered with a brooding expression.
He, too, had wondered what the hell he was doing and began to doubt whether this was a good idea.
Kim gave him a shy smile and he couldn't help but return it.
She was barely inside when Sean pushed her up against the door, his mouth on hers, his hands in her hair.
Now that he had a taste of her, he couldn't seem to stop.
She slid her arms over his shoulders and ran her fingers across the nape of his neck.
Sean finally broke the kiss but kept their bodies pressed together.
"I'm sorry about Adam and all that," he said before Kim interrupted him.
"Let's not talk about him, okay?" she softly said.
They stared at each other for a moment, neither wanting to move nor discuss what exactly they were doing.
"Are you hungry?" Sean finally asked. Kim smiled and nodded.
They quietly ate sandwiches before retiring to the couch to mindlessly watch TV.
As primetime gave way to news and talk shows, Kim stood and stretched.
"I should go," she said, looking down at Sean. He caught her hand.
"Stay," he said. She started to protest.
"Please? No funny business, I promise. Just spend the night with me," he pleaded, his eyes searching hers.
Unable to deny the man who always had her back, Kim slept in Sean's bed that night, his body curled around hers. Before dawn she crept out of his place and went home to freshen up before their next shift.
They didn't talk about whatever this was or touch when they were around the precinct, knowing that as partners they would face so much scrutiny from the sarge, not to mention Ruzek and his team.
At least Jay and Erin begrudgingly had Voight's blessing. They knew Platt would disapprove and permanently separate them.
Days into their newfound relationship, Sean arrived at Kim's place one evening with food and movies.
She grinned at him when she let him in. He had told her he had plans for them but wouldn't give her any details.
"So what do we have here?" she asked, attempting to reach for the pizza box in his hands. He gave her a cocky grin and pushed past her toward the kitchen.
"You'll just have to wait and see," he said.
They sat on the couch as they ate pepperoni pizza, laughing and groaning as they watched "Spaceballs" and "Hitchhiker's Guide to the Galaxy." When the final credits rolled, Kim turned to Sean, her eyes sparkling.
"Best date ever. I wouldn't have pegged you a sarcastic space junkie," she said.
"Just wait until I get you hooked on 'Firefly,'" he replied, reaching out to wipe sauce from the corner of her mouth.
Their eyes locked and the heat in the room rose by 10 degrees.
Seconds after their lips met, Sean pulled Kim to him and she straddled his lap. He let out a moan when she rocked on his rapidly growing erection.
"Bed," she whispered against his lips. He pulled back slightly and looked at her with hooded eyes.
"You sure?" he hoarsely asked. She answered by tugging him up and pulling him toward her bedroom.
As their clothes fell away, Sean hesitated as he hovered over her.
"I didn't bring anything," he said. Kim smiled up at him, lightly touching the side of his face.
"IUD," she replied. "I know we're both clean."
He shifted and settled between her thighs, sinking into her. She closed her eyes and happily sighed.
A/N: Will write more on this ship, maybe even add onto this one, if I hear you want it.
