A/N: Sorry for going on hiatus so much and not actually writing anything in a while. I've been so busy studying and having mental breakdowns for my last few exams so fanfiction has been the last thing on my mind. I felt bad for updating however so here's L, suggested by an anon. Thanks anon!

Two more exams to go thank God!

I don't own these characters.

From the very first day Special Agent Seeley Booth had met the one and only Anthropologist Temperance Brennan he knew that those lips of hers were not only good for sprouting facts about bones and forensic anthropology. He always suspected there was something more about them, even when they argued over the pettiest things; no good could ever come from her lips.

Well there was one exception and Booth was only just discovering what good talents that his Bones possessed with her ohsotalented mouth that was currently proving every assumption he possibly held absolutely correct as it was wrapped around his cock.

His hands instantly laced into her beautiful auburn locks in his pleasure begging under his breath that she'd at least locked the door of her office and that there were actually no security cameras in her office otherwise who ever was going to watch the security tape was probably in for a surprise and a good show at the same time.

The agent's hips thrust towards her mouth as she knelt near him at the end of the couch, her tongue swirling over the head of him causing a loud groan to tumble from his lips. Booth felt like he was in heaven, sneaking a glance down at her as she smirked up at him her hands resting at the base of him before taking him just a little bit more into her mouth.

"Jesus… Bones…" he grumbled, hands fisting tighter into her hair and giving a soft tug; still worried that he might hurt her in the process. But the smile that was plastered across the anthropologist's face said otherwise as she smoothed her hand over the base of him and gave a tug that made his hips jerk forward in surprise.

Booth kept his eyes closed while his head rested back against the head of the couch any words that made it to his mouth died instantly as she continued her ministrations; too lost in his pleasure. The only distinguishable noises made were moans, groans, grunts and soft whispers of his name.

On a soft pop the agent only then noticed that she'd stopped her ministrations and he slowly lifted an eyelid only for it to shut straight closed again as her teeth teasingly nipped his upper thigh. In that moment he could come to the only conclusion that she was going to be the absolute death of him.

"Bones… what are you doing?" he questioned, attempting to sit upright as much as possible while she continued to nibble at his thigh.

Brennan's head shot up instantly, a sweet almost innocent smile spread across her face while her eyes told a completely different tale. The cerulean blue had darkened to an almost navy colour, her hand unconsciously smoothing along his thigh only proving to intensify his arousal tenfold.

"I'm seeing how long you'll last." She explained as though it was the simplest thing in the world. "It's an experiment." Brennan added with a smile and before Booth could even object she'd wrapped that talented mouth back around him again.

The agent was suddenly at her mercy again one hand fisting in her hair while the other gripped at the upholstery of the couch until his knuckles turned white. All he could feel was the pleasure that surged through his body with every swipe of her tongue over the head of him or the way her head bobbed against him.

Just as soon as the pleasure returned Brennan pulled back again, watching him with curious eyes and a devilish smirk as she determined his reaction only to continue as though nothing had happened. This continued for what seemed an unbearable eternity until his hands fisted that tightly in her hair that he tugged just enough to pull her head up, their faces inches from each other.

"Bones... You're killing me here. I've had enough, make me come." He demanded as calmly as his ragged breathing would allow him, hands stroking over the sides of her face.

Their lips met in a slow kiss her tongue running over his bottom lip and demanding entry that he allowed their tongues meeting causing a shudder of pleasure down his spine. Brennan pulled back abruptly, her lips tugging up in a smile before she slinked down and took him in her mouth for a final time.

Booth groaned louder now, knowing how close he was to release and just the thought of her talented lips wrapped around his cock again set him off. His fingers laced into his hair as he came, pumping into her mouth and tugging as softly as possible on the strands.

When he came back to reality he found her lips pressed to his, faintly tasting himself on her lips when they pulled back his lips sought out the soft skin of her neck, hands skimming along her arms.

"Well you know…" the anthropologist whispered breathlessly as he nipped at the sensitive spot where her ear and neck connected. "We do still have twenty minutes on our lunch break." She suggested as he tugged on the hem of her work pants.

The suggestion coming from her heavenly lips sounded absolutely perfect to him.

A/N: So what did we all think? Love it? Hate it? Lemme know in a review? Any suggestion for M?
