This one is rated M. Haha, not sure why I feel the need to tell you this, since they all pretty much are, but, I don't know…this one just feels more M than the others.

You decide!

"Booth…" Brennan's voice was tinged with exasperation. "I can't concentrate when you're pacing like that."

Booth stopped walking and ran a hand through his hair. "Well, sorry…but it's hard for me to just sit there and wait. You know that." His hands landed on his hips, and even in his t-shirt and sweatpants, he posed an impressive figure.

"I know," she murmured and stood up. "Why don't you just go for a run or go to the shooting range or something like that?"

"No, no…" he insisted. "I'm not leaving you here in your office until we are done with the paperwork."

"But your portion is done, Booth. It's a Sunday afternoon. I'm used to doing this on my own. There's no one else here at the lab, and I just have to finish my portion of the paperwork, and I can't do that if you're…bothering me."

Her voice was breathy, and her cheeks were flushed, and Booth frowned. "I don't mean to bother you," he finally spoke through gritted teeth. "But we're partners." His eyes flickered to her barely rounded belly. "We're other things too now, but…this stuff," he motioned between them and her desk where a few file folders were opened. "The work stuff? That stuff is the same."

Brennan placed a hand on his arm, soothing him a bit with her soft touch. "I know." It secretly pleased her that he'd come to the lab with her because he wanted to spend time with her. Her fingers curled into the soft, worn fabric of his shirt. She liked that their intimacy meant she got to see him in all states of dress and undress. She loved him in a suit, but she also liked him casual. "I also know of a way that would help you relax."

Booth grunted, and then realized she was serious. His eyes flew to hers in surprise. "Um…that's funny, Bones."

"I'm not joking," her eyes were wide and clear and without artifice.

Booth pressed his hands to his hips and stared toward the floor to ceiling glass that was her office wall. From where he stood, he could see the empty lab platform, and his mind whirled with possibility. Wait…no, "No, Bones…come on…I'll just go for a run or something like you said."

But her mind was made up, and with a smile, she led him over to the couch in her office. "Wait," Booth stopped her.

"Booth," she started to talk him into it, but stopped when she saw him moving the couch so the back of it faced her office door.

"There," he breathed a bit heavily from the effort and then sat down. He patted the couch on either side of him with a smile and a soft blush against his high cheekbones. His boyish anticipation contrasted with the sexy weekend stubble on his cheeks and his wide shoulders. "C'mere, Bones…"

Brennan leaned down and kissed him, but instead of straddling him like he wanted, she slid to her knees in front of him. Before his mind registered her actions, she'd already loosened the drawstring of his sweatpants and in one fast motion, she'd pulled them all the way to his feet. "Bones," he groaned, a tinge of warning in his voice. She just looked up at him with a saucy smile and unfastened the button of his soft grey boxers. She left them on him, figuring if for some reason, they were caught, he at least wouldn't be completely naked. With soft fingers, Brennan reached into the slit of his boxers and wrapped her fingers along his half-hard penis. His skin was velvety smooth, and the tip was rosy, but not as dark as she knew it would soon get. With one hand she held him while the other hand stroked over his length. He seemed to grow harder and thicker with every swipe of her palm over the head of his cock, and when she brushed her thumb against him there, his feet planted to the floor and his hips shifted as a low mottled groan escaped his lips.

She smiled and then stood up. Then she straddled him and nearly laughed at the slightly disappointed look on Booth's face. He'd wanted her in that position before, but his instinctive male reaction at not receiving oral sex had been impossible to hide. "Don't worry, Booth," she gave him a smooth tug. "I'm planning on you coming in my mouth."

He let out a harsh moan, and Brennan took the opportunity to press her mouth against his. She was going to suck him off eventually, but first, she wanted him to feel her mouth on his mouth before she wrapped it around his cock. She wanted him to feel the warmth and curve of her cheeks, to recognize the texture and raspy slide of her tongue.

Booth's hands clenched at his sides and just when he clutched her hips, she moved away and sank back down to her knees. She took him in hand and stroked upward, using her thumb to once again tease the head of his cock. When she finally leaned forward to lick just the tip, she kept her eyes on his face. Like always, his neck corded, and his eyes narrowed. She loved putting that look on his face; it gave her an incredible rush. She loved the tiny crinkle-frown between his eyebrows. She knew that nothing would make that go away except full release. And she intended to give it to him.

With her hands on his thighs and her thumbs rubbing his sac, she teased him. Licking gently. Alternating between sucking his shaft and the head of his cock. "I love the way you taste," she murmured appreciatively and when his cock responded by growing and hardening with nearly every lick, she rewarded him with another hard suck.

"God, Bones…your mouth," he praised. Booth lifted his arms over his head and clenched the back of the couch for leverage as he pumped forward once, then again. Brennan took him all the way in and used her tongue rapidly on the underside of his head on his pull out. "Fuck," he cursed and left one muscled arm straining over his head while his other hand immediately cupped the back of her neck, his long fingers spearing through her hair and loosening the ponytail there.

He massaged her skull with his fingers, and Brennan mimicked the rhythm on his balls with her hand. She lifted off of him and paused, staring down at the drop of precum pearling against his tiny slit. With one index finger, she swirled the moisture against his plummy head and made him nice and wet. She licked both of her palms, then wrapped both of her hands around his shaft—one at the very base and the other just above it. Her knuckles were lined up in a perfect row, and she squeezed from the bottom up, simulating a clenching moist pussy. Booth groaned and his fingers in her hair tightened to an almost painful level. Brennan leaned forward and took the rest of his penis into her mouth. She sucked, hard, using her own saliva and his arousal to make everything very wet as she rose and fell against him. As she sucked him off, she loosened her grip with every slide out and tightened with every push in. She moaned encouragement and licked all around the head of his cock for an excruciating minute before sucking him back in again.

Booth's eyes were squeezed shut, but his other senses seemed heightened. He heard the sloppy suction and release as her lips popped around his hard dick. And oh, fuck…the feeling.

He thought he was going to come out of his skin…not just through his cock, but everywhere. He palmed the couch cushions on either side of his hips and rocked forward as best he could. The couch was soft enough that he wasn't getting good leverage. But it didn't matter, because she was somehow pulling and sucking and working him so exquisitely. When she pressed her tongue against his slit, the sensation was so piercing, he thought he was going to come right then. Somehow he didn't, and in the back of his mind, he registered her doing that little finger near his balls trick that always pulled him back from the edge. She was building him up—not just getting him to explode. Though he was plenty close to both. "Uh, uh, uh, uh, uhhhhhhhhhhhh," he clenched his teeth so hard he thought he might break his back molars. When she released him from her hands and took him all the way into her mouth, he tossed his head back and groaned. His feet were on the floor and he planted them wider, trying to give her more room between his thighs. All the damn room she needed, she could have. She wasn't sucking at all…just slowly sliding her lips up and down, making him so wet.

"Me too," she murmured, and he realized he'd said the words out loud. Oh, yeah. He knew she liked sucking him off. She'd told him quite early on in their relationship that oral sex excited her…giving as much as receiving. He'd been happy to tell her that he felt the same. In his mind, he imagined burying his face between her thighs. It was dangerous mental territory, but he couldn't resist. He knew as soon as he imagined licking her sweet little clit, he'd likely come.

"Bones," he rasped. "This feels so good…I'm about to…I'm gonna…oh, fuck," he warned, but it was also begging. And he cursed low in his throat when she gave him what he needed, once again wrapping her tight hands around his pulsing shaft and sucking hard on his throbbing tip.

Brennan tightened her mouth around him and paid special attention to the ratio of speed and movement in her sucking. Her tongue was swirling, and she sensed the moment when he froze. And then his upper body was falling forward; his hands landed on her shoulders and he cried out in ecstasy as he came in her mouth. She stayed with him all the way, pumping him gently with her hands until his balls finally relaxed downward and his body stopped shuddering. Only then did she gently pull her lips away from him.

A silky drop of fluid lingered on her lip, and Booth watched as she swiped at it with her tongue. He groaned and pressed his forehead against hers, breathing in her scent and trying to come up with the energy to thank her. Brennan cupped his face in her hands and lifted up on her knees, pressing a kiss to the soothed spot on his forehead between his eyebrows.

She smiled at his full release and then climbed up to his lap. "What do you have in mind for dinner?" she asked him as she stroked his shoulder.

His lips parted, "Bones, you gotta give me a little more recovery time here."

Her fingers traced down his chest to where his penis was not still resting outside of his boxers. He wasn't soft and had the possibility of hardening again. "You seem to be recovering quite nicely," she commented with a slide of her thumb.

Booth groaned. "Not my dick…my brain. Jeez, Bones," he breathed with an adoring smile. "When you blow me, you blow my mind."

She laughed at his words and kissed him before standing up and leaving him on the couch. She made her way back behind her desk and looked at him. He was still sprawled out with his sweatpants pooled at his feet.

"Why don't you take a nap," she offered, hiding a smile. "I'll wake you up when I'm done."

He smiled at her and stretched out onto his back. "Okay…sounds good, Bones."

She smiled and shook her head and got back to work.
