Erin used the key she had been given to walk into Kelly's house and followed the sounds of him tinkering in the kitchen, a smirk on her lips. She was in the mood to play and luckily for her, Kelly was always up for anything. When she entered the kitchen, she saw that he was working at the sink.

"Couldn't reach a plumber?" she asked, causing him to jump at the sudden voice, causing him to hit his hand with the tool he had been using. "Sorry," she apologized.

"Ow! Damn it," he complained, shaking his hand, trying to drive the sting away.

"Sorry," she apologized again. She hadn't meant to startle him.

"It's fine," he responded. "And in answer to your question, I actually know how to do a bit of plumbing. But don't worry, if it's something I don't know how to do, I'll call someone," he continued, going back to work.

"Hey, it's your place," she responded with a shrug. If he was able to fix whatever was wrong with his sink, good for him. But it was also nice to know that he apparently wasn't above calling someone for help if he couldn't do it. For a few minutes, she watched him and then without saying a word, she walked up to him, placing her hands on his hips and moving them down his sides.

"Whatcha up to, Babe?" he asked with a grin. For an answer, she just placed a foot between his legs, forcing them apart.

"Assume the position, Lieutenant," she seductively ordered.

"What seems to be the problem, Detective?" he queried as he followed her instructions, trying not to moan at the feel of her hands running up and down one leg than the other. Damn! Does she realize how hot this is? he wondered.

"You have been charged with leaving me all hot and bothered this morning," she answered, keeping up her "frisk".

"Guilty, but I have a good reason. I was about to be late for work and so were you," he responded. It wasn't like he could tell Boden that he couldn't come in because he was in the middle of ravishing his girlfriend. And he doubted Voight would've been pleased to hear that she was with him.

"Mmm. That is a good reason," she allowed as her hands once more traveled upwards. "But that doesn't mean you're going to get out of your punishment," she told him, cupping his bulge with a hand, smirking when she felt the tightness in his jeans. "Hmm…I think someone enjoyed that," she commented. She then began stroking him through the denim and he let out a moan. Damn, she felt good! As if spurred on by the sound, Erin sped up her actions, and the firefighter grasped the edge of the sink to resist turning around and grabbing her. The detective's smirk grew. "Like that?" she asked, whispering in his ear seductively.

"Mmm.." was all he was able to get out.

"Turn around." Grinning, he did so, kicking off his shoes even as she did the same before grinding against him, resulting in a ragged moan. She then undid her jeans, letting them drop to the floor before stepping out of them and removing her underwear, kicking off her shoes. Almost immediately after, she rubbed against her boyfriend again, undoing the belt of his jeans and then slowly sliding it out of the loopholes before dropping it to the ground. Kelly's breathing hitched and he stared at her, lust in his eyes.

"Babe," he whispered hoarsely. For answer, she undid the button and then pulled his jeans down, letting the fabric pool at his ankles. He stepped out of the jeans and kicked them away. Then, she once more pressed her body against his, going to enter him and the firefighter's senses was filled with nothing but his detective girlfriend as they got lost in one another.

THE END
