I got this idea from another fanfic that i read, but i wanted to change it and add my own ideas.
Almost everyday for the last 2 weeks, Booth has came home and headed straight to the bathroom for a cold shower.
He's always found Dr. Brennan unbelievably attractive and more often than not, his mind wandered to images of seeing her sprawled naked on his bed, bent over his desk or pounding her against a door, but recently he found that when he returns home he finds himself needing to jerk off more and more as the images of her flood through his mind.
He couldn't quite put his finger on what it was that was effecting him so much, until one day it hit him and he noticed everything he had missed.
Her low cut tops making her breasts bulge out over her shirt as she leaned over his desk to fix his tie or pick up something. The way she held her arms, making her dress stretch and mould to the curves of her body. Her skirts becoming slightly shorter and her pants becoming tighter. She touched him more, a lightly placed hand on his thigh, her ass brushing against him when the elevators got crowded.
She was playing him.
Temperance Brennan was never good at subtle, but clearly she had learned and he missed it.
Booth thought back over the last few weeks. Re-playing every move she made and every word she spoke that made him sweat.
Well. He thought. Two can play this game.
...
The next day Booth strode into the bone room at the Jeffersonian.
He was determined that he wasn't going to let her think that she could keep up this charade thinking that he hadn't noticed.
She was wearing tight, dark blue jeans and a sheer, white shirt over a white tank top. He blue lab coat draped loosely around her leaving a clear view of her breasts. And she stood slightly bent over as she examined the bones.
"Found anything, Bones?" He asked as he walked over and stood behind her like he always did.
"There's a fracture to the left tibia and some small indentations on the 3rd and 4th ribs. But nothing showing obvious signs of cause of death."
"Well don't worry Bones. You'll find it." Booth stood closer to her and lightly pressed himself against her.
"I'm not worried, of course i'll find it and stop patronising me."
He leaned his head of her shoulder. Making sure she could feel his breathe on her neck. "What's that there?" He brought his arm around her waist and pointed at the bone in her hand.
"That's a bone Booth. There's nothing on it. And why are you standing so close to me?" Sh placed the bone back on the table and tried to turn around. Booth held his hands on her hips stopping her from moving.
He moved his head so that his lips were almost touching her neck. "I know about the little game you've been playing with me."
"Booth, i don't... "
He quickly interrupted her. "Don't try and deny it. I'm just letting you know that it's over. You've had your fun, but you lost."
Brennan pressed firmly back into him and ground her ass into his pelvis. She tilted her head back onto his shoulder and whispered in his ear. "The game isn't over yet Seeley. It's just getting started." She pushed against him and he stumbled a few steps backwards giving her space to walk away.
She stopped just before the door and turned to look at him. "By the way Booth. I never loose." A wicked smile scraped across her face and she walked out the room.
...
I know this is short, but i'm wanting to try and carry the storyline on for a while.
