A/N

Sorry (again), but after another longer than planned hiatus, I'm finally in a position to post again. This is the last chapter in this story, which is still 9 more chapters than I intended when I first wrote chapter 1 as a one shot! I always find final chapters the hardest to write – I'm much more of a drama person, and find "and they lived happily ever after" really difficult. But hopefully this ending works for you all

Emily was sat at her desk when she felt her phone vibrate in her pocket. She forced herself to keep a straight face when she saw who her message was from. The fact that the blonde was choosing to message her personal phone meant that she had anything but work on her mind.

JJ: You need to find an excuse to come to my office

The brunette failed to suppress a smirk as she typed a reply.

Emily: I assume you have something very important and work-related to show me?

JJ: Quit being funny and get your sexy ass in here

Emily cleared her throat and stood up, deciding that the blonde probably wouldn't take kindly to any further winding up.

"I'm just going to see JJ about a case" she announced to nobody in particular.

"Oh" Spencer stood up "I was just about to run something past her, let me come…"

"How about I take a look first?" Morgan interrupted, sliding his chair over to Reid's desk.

"Sure" the younger man shrugged "if you have the time?"

"I've always got the time for you, pretty boy"

Emily smiled at Morgan gratefully, and made her way to JJ's office. The door was ajar, but she still knocked before entering without waiting for a reply.

"Hi" the brunette smiled.

"Hi" JJ replied brightly, before lowering her voice "I suggest you shut the door behind you"

Emily did as she was told, closing the door and locking it before slowly making her way across the room. Her eyes were fixed firmly on the blonde's, and at the same time JJ got up from behind her desk and made her way around it.

The brunette bit her lip as JJ came fully into view. She unashamedly let her eyes rake up and down the blonde's body, her pupils dilating as she did.

"You know what those skirts of yours do to me" Emily's voice grew husky.

"I do" the blonde smiled "but do you know what its been doing to me all day, ever since I put this skirt on, knowing how it would make you react?"

"Fuck" the brunette growled "what are you doing to me?"

"Well I do have something to show you" JJ bit her lip as she slowly began to slide her skirt up, revealing more of her toned thighs "but I promise you, it is very, very, unrelated to work"

"Jennifer…"

"Come closer" the blonde commanded.

Emily swallowed "I don't know if I can"

Keeping hold of her skirt with one hand, the blonde reached out with her other hand and took hold of Emily's wrist, pulling her in. Her eyes stared straight into the brunette's as she guided her hand under her skirt.

Emily could do nothing but whimper as her fingers made contact with the wetness between the blonde's legs.

"Jen…" she groaned, gripping JJ's collar as she pressed her cheek against the blonde's "what happened to your underwear?"

"I took it off before I asked you to come up here" the blonde rasped "thinking about you just kept getting me wetter and wetter"

"Oh my god" Emily moaned.

JJ released her grip on the brunette's wrist, immediately taking hold of her hips to steady them both. Their cheeks were still pressed against one another, so that each of them could feel the other's breath against their ear.

Emily let her fingers explore the blonde's core, exhaling as she felt just how wet JJ already was. She brushed her fingertips over the blonde's clit, smirking as she heard the resultant gasp.

"Emily!" the blonde moaned, tilting her head backwards.

The brunette kissed her way up JJ's neck, before capturing her lips in a deep kiss at the exact same moment as she entered her with her fingers. The blonde moaned loudly into Emily's mouth as they kissed desperately. Their tongues were intertwining, and the force with which JJ was gripping the brunette's hips was probably enough to bruise, but neither woman cared.

Emily pulled back slightly from the kiss, panting "I told you…before…that I had fantasies about you in these skirts…"

The blonde swallowed "You did"

"Please will you let me fulfil another fantasy?"

JJ kissed the brunette softly "Right now, I'd say yes to anything"

Emily took a step backwards, and waited for the blonde to look at her through hooded eyes. In that gaze, she saw nothing but pure unadulterated want. Slowly she dropped to her knees, maintaining the eye contact with JJ.

"Oh my god" the blonde groaned, her hands moving to grip the edge of her desk.

The brunette slid her hands up JJ's thighs, pushing up her skirt until it was bunched at her waist. She hadn't been lying or exaggerating when she'd said this would be fulfilling one of her fantasies. She'd told JJ before that seeing her in her a skirt had made her think about fucking her against her desk. But being on her knees in front of the blonde, being able to go down on her whilst she was still wearing one of those damn skirts…this was absolutely something that Emily had been imagining for a long time.

She inhaled deeply, taking in the scent of the blonde. Her hands kept hold of JJ's hips firmly, pressing her against the desk as she buried her face between her legs. She ran her tongue up the length of the blonde, taking in every bit of her and moaning at the taste. She focused on JJ's clit, sucking it into her mouth before releasing it and lapping at it with her tongue.

"Fuck, Em…" JJ moaned, moving one hand to grip the brunette's hair whilst the other firmly clutched the edge of the desk against which she was still leant "you're so fucking good at that"

Emily smiled, and begin to kiss the blonde's clit, ensuring that her tongue dragged over it as she felt JJ quivering. She kept moving her mouth, feeling the blonde react every time her tongue flicked over her clit. The fingertips digging into her scalp served only to encourage her further, and she continued to move her tongue with vigour. She drew patterns over JJ's clit, before kissing her centre deeply, with every action resulting in a loud moan from the blonde. Hearing the way that JJ was responding to her, she let her tongue run down the blonde's core. She flattened her tongue, and pressed it firmly into JJ, taking as much of the blonde into her mouth as she could.

"Oh my god" JJ panted "Fuck…that's so fucking good"

Emily moved her hands so that she was gripping the blonde's ass, which allowed her to press her face harder against her core. She couldn't help but moan herself at the taste of the blonde that was filling her mouth.

"Em!" JJ gasped "Fuck you're gonna make me…fuck…"

The blonde's knuckles were going white from the ferocity with which she was gripping the desk. She clenched her teeth, desperately trying not to cry out too loudly as she felt the orgasm hit her.

Outside in the bullpen, Morgan's attention was caught by the sound of Hotch's office door swinging open. He watched his boss make his way out of his office, and after waiting a moment, noted that Hotch was making a beeline for JJ's office.

Morgan jumped out of his chair and practically leapt across the room, sprinting up the stairs so that he reached JJ's office door seconds after his boss.

"Hotch!" he greeted him over-enthusiastically.

Hotch frowned "Can I help you Morgan?"

"Yes! Reid and I were actually just discussing a case, and we hadn't wanted to disturb you, but now that you're…available….well, we could do with your expert opinion" Morgan tried to smile convincingly.

"First, if you need my opinion, you know that you can always knock on my door. And secondly, I really do need to speak to JJ…" Hotch reached out for the door handle.

"W-wait!" Morgan called out "We really could do with your help"

"And I will come see you once I've spoken to JJ" Hotch replied firmly.

"I wouldn't…" Morgan winced as he watched his boss turn the handle.

"Morgan, what are you…" Hotch paused and glared at the handle as he realised he was meeting resistance and was unable to fully turn it.

"Seriously, if you'd just come with me…"

"JJ!" Hotch called, rattling the door handle and seemingly ignoring Morgan's pleas.

"Hotch…"

Hotch's eyes narrowed and he glared at Morgan suspiciously "You want to tell me what's going on?"

"Nothing's going on man, we could just really use your help"

"Jareau!"

Morgan and Hotch stared at each other for a few awkward moments until JJ finally opened the door.

"Hi boss, you need me for something?" the blonde asked brightly.

Hotch's eyes narrowed and he pushed the door so that it opened fully. This revealed Emily, casually leaning against JJ's desk with a file in her hand. He slowly moved his gaze from one woman to the other.

"Prentiss. Jareau. My office. Now. And you…" Hotch turned his attention back to Morgan "I will speak with you later"

"Oh my god" JJ covered her face with her hands, slumping down onto Emily's couch.

"Babe, you're assuming the worst" Emily stood in front of her and handed her a glass of wine "You don't know that he heard anything"

"Come on Em" the blonde glared at her, but accepted the wine "he was right outside the door, he totally heard. Why else would he give us the whole lecture about keeping our relationship professional in work hours?"

"Because he's a profiler. He didn't need to hear us having sex to put two and two together, and make four"

"But what if he did?" JJ took a large gulp of wine "How the hell am I going to face him on Monday?"

"Jennifer" the brunette knelt down in front of JJ, putting her glass of wine down so that she could rest her hands reassuringly on the blonde's thighs "we both know that we haven't exactly been the best at hiding our relationship recently. You said yourself that the night at the bar, nobody except Reid bought your excuses for us leaving"

JJ groaned, putting her own wine down on the side table "Why do you always have to be so calm and rational?"

The brunette laughed "One of us has to be"

Arching an eyebrow, the blonde leant forward, pausing with her lips millimetres from Emily's "And what is that supposed to mean?"

"It means I'll always be here to calm you down" the brunette reached up tenderly, tucking JJ's hair behind her ear.

"You're so damn smooth" JJ chuckled, closing the gap between their lips.

The brunette smirked into the kiss, but soon found herself moaning as JJ's tongue invaded her mouth. She slid her hands up the blonde's thighs, pushing her skirt up as she leaned in with her upper body.

"You know" Emily whispered, slowly kissing her way down the blonde's neck "there was so much more that I wanted to do to you in your office earlier"

The blonde swallowed, tilting her head to make her neck more accessible "Oh yeah?"

"Uh huh" the brunette grazed her teeth over JJ's earlobe "and what I really, really want to do is hear you scream"

JJ leant back, her cheeks flushed, so that she could stare into the brunette's eyes "In that case, you'd better come up here and fuck me hard"

"Yes ma'am"

Emily leant back on her heels, watching through darkened eyes as the blonde unbuttoned her shirt and lay down on the couch. She hovered over JJ, unzipping her skirt and sliding it down over her legs.

"You know that every time you wear one of these skirts now, I'm going to imagine that you aren't wearing any underwear" the brunette crawled slowly over JJ's body.

"I guess you'll always have to find an excuse to put your hand up my skirt and find out" the blonde winked.

"Darling" Emily leant down and kissed the blonde slowly "I never need an excuse to touch you"

"Emily?"

"Yeah?"

"Less talking, more fucking"

The brunette reached between their bodies and slid two fingers into JJ "Like this, you mean?"

"Oh my god!"

Emily rested her weight on one forearm, leaving her other arm free to thrust into the blonde. She used her thumb to make contact with JJ's clit with each thrust, loving the gasps that each movement caused.

JJ clutched at the brunette's back, desperate to feel even closer to her. Unlike their earlier encounter in her office, she had no need to hold back now, and she grunted loudly every time she felt herself being filled with Emily's fingers.

"More" she begged "I need more"

The brunette kissed her deeply as she added another finger and used her hips to increase the pressure behind her thrusts. JJ cried out, and slid her hands down so that she was gripping the brunette's ass in order to pull her body hard against her.

"Emily…fuck!" she groaned, her eyes slamming shut as she let her whole body be taken by the brunette.

"Don't hold back baby" Emily purred "let me hear you"

"Just like that…please….right there…"

The brunette's thumb slid over JJ's clit one last time, and the blonde came completely undone. Her loud cries filled the air as she clung to Emily desperately.

As she felt the blonde's body slowly begin to relax, Emily stilled her fingers, but left them inside her. JJ blinked her eyes open and gradually managed to focus on the brunette above her.

"Hi" she smiled shyly.

"Hey you"

"I love you, you know that"

"Yeah" Emily grinned "I think I do. So, you feel better about things now?"

"Right now" JJ reached up to cup the brunette's cheek "I feel nothing but you. And that's exactly where I'm meant to be"
