Hi there!

I have another one shot for you all! This prompt is from PenguinsPenguinsPenguins: Based on the song I Get Off. I used the song as guidance, but changed it up just a bit. Definitely different from what I normally write, but I like a challenge. I hope you like it!

**This is an M rated one shot.**

Thank you all for your reviews, favorites, and follows. It truly means so much to me! Feel free to send in any ideas you have and to continue reviewing.

Enjoy!

He was watching. She knew he was standing there; still, quiet, and ever so hungry for her. But he was in the shadows, just like he always was when it had been too long since seeing each other. They had been apart for seventeen days. Seventeen days of tours and work and little communication. And now, after a long day of work, just waiting for the moment when she would be reunited with him, she knew that her seventeen day hiatus would finally be rewarded. But not without a little fun first.

When she walked into the loft, it was quiet. She knew he was home, but there was no use calling out for him or searching. Instead of kicking her heels off and hanging her coat in the closet, she strutted straight through the loft and into their bedroom, sighing when she reached the door frame. "Oh Rick." She called out in a sing song voice, her eyebrow raised and lips pouty.

She stopped and listened for a moment, only hearing the faint sound of a floorboard creak from behind her. Kate ever so slowly untied the belt holding her coat so closely to her body, and let it fall from her shoulders and drop silently to the floor. She had a few tricks up her sleeve for tonight. Because when the coat dropped, all she had on was matching black lace and her four inch stilettos. Oh what she could pull off in the front seat of her cruiser. "Ahh, much better." She stepped fully into the bedroom, continuing on with her performance.

Ever so seductively, she positioned herself in front of the mirror. Hands pressed into the wood, she leaned forward, letting her perfectly toned and shaped body do all the talking. She reached up to her hair and removed the pins, her curls cascading around her face. Kate ran her hands through her hair, still facing the mirror. Her lips perfectly pursed, she listened again for where her could be, hiding in the shadows, like an animal stalking its prey. Oh how she loved being the prey.

From what she heard, Castle moved closer. The door leading to their room from the study creaked and then went silent. Perfect. She didn't dare look, though. That would ruin the fun. A smirk spread across her face as she stood completely up and turned towards the bed.

Swaying her hips, she made her way over to it and sat on the edge. Kate bent over and took off both shoes, running her hands up her legs, stopping right between her thighs, hovering over the hem of her underwear, then over her hips, and up to her chest. She reached behind her back to unclasp her bra, but stopped. She smirked again and shook her head, standing back up and making her way to the window. Kate pushed back the curtains and watched the city below, counting backwards from twenty in her head.

Twenty, nineteen, eighteen, seventeen.

She heard the door open slowly from across the room.

Sixteen, fifteen, fourteen, thirteen.

She couldn't help but stick her ass out ever so slightly as she heard footsteps behind her and then stop. She saw his reflection in the window standing behind her. Whether there was a bulge in his pants or a ripple in the glass of the window, she would soon find out.

Twelve, eleven, ten, nine.

She felt a pair of arms snake around her waist. He was eager tonight. He pulled her close, his fingertips grazing her skin lightly. His lips met her neck, peppering her skin with kisses. She leaned into his touch, closing her eyes and letting out a shaky breath. Seventeen days was a long time.

But she wasn't done just yet. She moved her hand to his upper thigh, slowly tracing it. She felt him tense up and hold her tighter. She just loved driving him wild. She reached behind her, turning her head so their lips almost touched. She ran her hand down his cheek and over his lips, hovering in place.

In one swift motion, he turned her around, pressing her up against the window. She wrapped her arms around his neck as his hands danced around her waist. She let out a moan when his hand traveled down to pleasure her. He growled at her smiling as her nails dug into his back. Now he was in control.

She quickly tore off his shirt, running her hands down his chest to the waist band of his dress pants. She unbuckled his belt and worked at the zipper herself before he became impatient. He finished the job himself, kicking off the rest of his clothes. Then in the next second, reached behind Kate and unhooked her bra, tired of playing games. He pulled her closer still, their faces just inches from each other.

"So, how was your day?"

"Oh cut the crap, Rick." Kate crashed her lips to his, letting her hands get stuck in his hair. She locked her legs around his waist, now completely wrapped in his arms.

Castle carried her to the bed, their lips never parting. He laid her down, hovering over her. A dangerous, hungry smile played on his face as he proceeded to get closer and closer to her.

Fire in her eyes, Kate clutched the sheets, eager for her fiancé's touch and the night that they had been waiting seventeen days for. When he was close enough, Kate reached for him, pulling him the last few inches to her. Their lips collided together once again, teeth crashing into each other.

He lowered himself to her, finally becoming one with the other. She let out a moan, one that sounded much like his name as he breathed out heavily. What started as a slow, playful act turned into quick, passionate action. They were in for a stellar night.
