A/N: Genre (for this chapter): Porn w/ Plot; Smut; Comedy Fluff

Rating (for this chapter): NC-17 (M)

I know that I was exaggerating a little bit … okay A LOT! in this fic! :D half of the stuff I wrote are unlikely to happen in one and the same night but … I don't really know what got into me! I just wrote that they've been doing it for like 3 hours or so! :D (not 'just' – I've been writing this for a long time but ya know what I mean ;) )

And 3 hours is a lot – maybe too much! I honestly don't know – half time is ok; really tiring but achievable when changing positions and from intercourse to oral but 3 hours! Really! Am I crazy or what? Anyway .. yea… uh.. why am I telling you this – you guys already know it!

And before I can say something even stupider I'll stop writing this author's note and let you read the storyyy…

Enjoy =]

******************************….

They both moaned at the feeling but kept kissing not wanting to break the contact. Reid gently moved them so he was on top of her once again. Soon she could feel the tip of his cock poking her clit and a few moments later him thrusting into her slowly earning a hiss. He halted his movements and Emily looked straight in his eyes; she pushed her hips off the bed against his. In a few thrusts they found their rhythm and slowly rocked their bodies to climax.

Emily wasn't sure; was it the dirty talking or some kind of over stimulation but an orgasm hit her out of nowhere causing her walls to come crushing down around Reid's erection. Her whole body was trembling and she felt extremely hot. She could feel the blood pumping in her veins and her heartbeat raising still a bit more as waves of pleasure took over her body and brain and no coherent thought made its way to her mind. Still she felt him coming within her and that sent yet another wave of pleasure through her body.

Spent. Out-of-their-minds. Hot. Breathing heavily.

Emily lay on the bed with Spence beside her both looking at ceiling trying to catch their breaths and return their composure. Emily was going to die. That was the most amazing thing she had ever done when it came to sex. Reid was a God!

"It's three o'clock." He murmured.

"What? Already?"

"The brain's judgement of time is known to be a highly distributed system, including at least the cerebral cortex, cerebellum and basal ganglia as its components. We were keeping our brains "busy" with the decrease in the metabolic activity of large parts of the cerebral cortex and with increasing or keeping normal the metabolic activity in its limbic areas…"

Emily was speechless. She just blinked twice. "Wh-" she started to ask but she cut herself off. Reid looked at her. "Forget it." she shook her head.

A few minutes passed just savouring the moment and resting. Strangely sleep wasn't overtaking them.

"Sometimes I wonder how you live with all the knowledge you posses." Emily told him softly.

"What do you mean?"

"Like the thing about the sex." Now he was completely confused. Emily exhaled and turned on her side to look at him while explaining what she meant. "So you know that the cerebral cortex takes part in the..." she wasn't sure how to put it but he clarified for her.

"Time perception."

"Yes, and doesn't work at its best during sex… so it's interesting how you know such things and they don't … dunno … bother you."

"I guess I just understand them and knowing what's going on in our bodies during sex doesn't bother me. I just know it and that's it."

"Pff..." a puff of air left Emily's lips. ... "Now what?"

"Now the endorphin levels are going back to normal and we should feel sleepy soon." Spence explained.

"No! I mean ..." Emily laughed, "I meant with us?"

"Nothing I guess. We're colleagues. But we could do this again sometime." Reid actually winked.

Prentiss smiled. "Believe it or not I don't think that I'll ever be satisfied with another man again."

"Why not?"

"I don't know what the other women you've slept with have told you but just in case you don't know – you're maybe the best there is." She nodded while saying it and was looking away from him in attempt to think about somebody better. She couldn't come up with anybody and she had some experience!

"What do you mean?" 'how sweet of him' she though.

"What I mean is that you are caring and you know how to do stuff and that you're pretty huge..." he was moving his body closer to her and smirking; "and you obviously know how to hold back and you don't only think about yourself and- what are you doing?" he was kissing her neck; slowly and gently. It was intoxicating. "Uh, Reid..." she lay on her back again enjoying the feeling of his lips on her hot skin. His mouth was on hers again kissing her with passion while his left hand was roaming over her thigh. Emily moaned. They both knew that sex was no longer a possibility because Prentiss did like to walk and do other of her daily activities without feeling pain so they just kept kissing. Soft moans and whimpers leaving her mouth and fading into his. Their tongues battling and retreating and desperately trying to make contact when it was needed. They both enjoyed the making-out session very much. It was so relaxing and kind of soothing.
