OOOOO

Dec. 9th: Groovycathers chose the word "moist".

OOOOO

Brennan unlocked her front door and set down her purse. She had been sent home at exactly five o'clock because it was her birthday and the lab insisted she celebrate it at home. She didn't know what she would do with her time exactly. Booth still had a few weeks in Afghanistan before his year of training soldiers was up and in his absence, Brennan's reports and work from Maluku were already done. Booth had promised that he would video message her as soon as he was able so she headed for her computer on the kitchen table.

She made it a few steps before she noticed that there was a square bakery box sitting on her table. She carefully opened the lid and smiled. Happy Birthday Bones was scrawled over the top of the chocolate frosting. She smiled at the surprise and looked for a card, despite the fact that she already knew who it was from. Leave it to him to remember to get her a birthday snack despite being in the middle of a war zone.

"Happy Birthday." A low voice came from directly behind her. She whipped around in surprise at the sound of his voice.

"Oh my God." She stared slack-jawed for a moment. "What are you doing here?" She asked as she flew into his arms.

"I wanted to surprise you." He said as he squeezed her fiercely.

"It worked!" She cried as he spun her around in a circle before setting her back down on the ground. She grasped his tanned face in between her hands and examined him for a moment. His eyes were bright, if not weathered from his time in the sun. He looked so happy that it made her stomach curl within her. It was then that she realized she hadn't kissed him yet. She grinned as she pulled him down for a mind-numbing kiss.

"Oh god, I missed that." He groaned as he rubbed noses with her. "Six months is too long to go without tasting you." He decided.

"Mmm, I agree." She said as she kissed him one more time. When she finally gave him space to breathe, she began peppering him questions.

"How long do I get to keep you?" She asked.

"Forever." Booth said as he handed her an envelope. She frowned as she looked down at it. "My discharge papers."

"What?"

"I'm out. My time is up." Brennan clutched the papers to her chest before looking at them again. "I dropped all my stuff off at my apartment this morning. I'm back for good." Brennan's eyes welled up with tears as she cuddled into his neck.

"This is the best birthday I have ever had." She declared.

"And we're just getting started." He said as he rubbed his hands together. "So, where am I taking you to dinner? My treat."

"Can we order in?" She asked. "I want to keep you all to myself tonight." He smiled that sappy smile he got when she was being romantic.

"Absolutely." He agreed. "And there's always cake for dessert." He added as she beamed at the cake on the counter. "It's mocha chocolate. The middle has ground up chocolate covered espresso beans in the filling."

"That sounds delicious." She told him. "Perhaps we should have that instead."

"It's your birthday." He reminded her. "Slice it up."

"Really?" She asked, a mischievous smirk appearing on her face. He nodded. "I have missed being spoiled by you." She confessed.

"I've missed spoiling." He said honestly, reveling in the excitement of being home and making her happy.

She got up and carefully cut a slice of cake for them to share. Booth sat down at the end of the table and sunk a fork into the first bite. He held it out for her and she smiled as she took the bite.

"Mmm." She moaned. "Oh that is so good." She smiled as she slid the piece of cake his direction. "You have to try that. It's so moist." When she looked up at his face again, his eyes were black. She paused, unaware of why he was looking at her like that. He bent over the corner of the table, moving closer.

"Those are the same noises, the same face, you make when I'm inside you." He said darkly. Her body instantly reacted to his words and she felt her chest tighten in desire. "Go ahead, take another bite." He requested roughly. She did as she was commanded and closed her eyes and licked the frosting off her lips. She heard his chair scraping back against the floor and she opened her eyes. He hurled her over his shoulder like she weighed nothing and carried her to bed.

"Oh God." She purred as she felt every rippling muscle under his t-shirt. She clutched at the hem and as he set her down on her toes again, she pulled his t-shirt over his head with her. "The Army has been good to you." She murmured as she took in his bronzed skin and new physique. He had always been a well-shaped man but his training had bulked him up and slimmed him down in all the right places. She pushed him down on the bed and straddled him, her hands desperately running over every inch of bare skin until they found his belt buckle and slid his pants and boxers to the floor.

"Not fair, Bones. Your turn." He said as he sat up and slid his rough hands up her back, sending goosebumps scattering across her skin. He held her by the small of her back as he pulled the blouse over her head. He didn't even bother removing her bra as he buried himself in her chest, kissing and sucking the flushed mounds of flesh. She fell back into his hands as he worshiped her until he finally reached around and unhooked her bra. She tossed it to the floor, already forgotten.

Now bare to him, Booth's mouth kissed her skin hungrily and she moaned again, grinding into his erection as her skirt rode up around her hips in the process. Realizing his loss, Booth reached up and ripped the damp panties right off her hips. She wanted nothing more than to sink down onto him but he had the presence of mind to unzip her skirt and she fell back onto the mattress so she could quickly discard the material.

Once she was completely naked, she climbed back onto his lap again and his hands guided her hips until she was hovering over his substantial erection. She let out a low groan as he lowered her down onto him and he finally filled her for the first time in months. Nothing, nothing, felt like he did and she shivered at the knowledge. His hands held her firm as she rotated herself over top of him. He kissed her with all that he had, pulling every emotion out of her as his tongue explored her mouth.

"Oh, Bones, Bones, Bones." His prayer thrummed in his throat and she felt it against her skin. It rumbled through her body and she felt herself begin to climb.

"Oh, oh, oh Booth!" Her hands clutched the back of his head as her orgasm tore through her, rippling from her core throughout the rest of her body. He lay her on her back before thrusting deeper and harder into her. Her hands slid around his hips and clutched him encouragingly as she arched up into him. He grunted as he spilled into her, shuddering hard through his own climax.

He slipped from her but he pulled her over top of him as he fell back to the mattress.

"Jesus Christ, Bones." He whispered hoarsely into her hair.

"I may never leave this bed ever again." She smiled against his chest. "Maybe only for the cake."

"Fuck yes" He agreed. "I think I could get off just watching you eat it." A tremor shimmered over her body at his explicit words.

"Give me a second to recover and then we'll find out." She promised.

"Deal." He said as he closed his eyes.
