Emily rolled her eyes at the smirk on JJ's face as they entered her apartment.

"I'm going to regret ever making that bet, aren't I?"

"I know I'm not"

"So, what can I do for you, my lady?"

"Well..." JJ stepped into the brunette, trailing a finger along her collarbone as she leant into let her mouth hover just in front of Emily's lips "I'm kind of parched from the run"

Emily swallowed "Uh huh"

"I'd like some juice"

JJ winked and pecked the brunette on the lips before walking over to the couch and laying down on it. Emily shook her head in disbelief. She was fairly sure that the next twenty four hours were going to kill her.

Once she had been presented with her glass of juice, JJ lifted her legs to let Emily sit down underneath them.

"You know, winning a race really can take it's toll on a girl's feet"

Emily raised an eyebrow, which just led to the blonde lifting a leg to wriggle her toes in the brunette's face.

"Are you kidding me?" Emily asked indignantly.

"Nope" JJ grinned "is there a problem?"

"Feet...aren't exactly my thing"

"Just a little foot rub babe"

Emily sighed "Fine. At least I guess you have nice feet"

"Thanks...I think"

The brunette took hold of both of JJ's feet and began to massage them "How's that?"

"Mmm" the blonde smiled contentedly and closed her eyes "that feels really good"

Smiling, Emily moved her thumbs in a circular motion over the balls of JJ's feet. She watched as the blonde's lips parted and she moaned softly. The sound caused a twinge between her legs and she increased the pressure that she was applying. Any vague dislike for feet was long gone as she saw how much JJ was enjoying the massage.

Although she hadn't been instructed to do so, Emily decided it was worth risking the blonde's wrath to start rubbing up to her ankles. When JJ just smiled, she moved her hands higher, sliding them firmly up and down the blonde' slower calves.

JJ's eyes opened and she started intently at the brunette. With each stroke of her hands, the blonde's breathing grew heavier and the rise and fall of her chest was evident. She said nothing, but there was a challenge in her eyes that Emily was more than willing to accept.

Emily shifted so that she was kneeling between the blonde's bent legs. Her hands cupped the firm calves as she slid them higher, letting herself reach just below JJ's knees where her tight fitted running pants ended.

"May I take them off?" the brunette asked.

JJ nodded her permission and lifted her hips up to allow the brunette to pull the pants down her legs. She dropped them onto the floor and rested her hands on the blonde's knees.

"Keep going" JJ instructed.

Emily kept her eyes on the blonde as she ran her hands up and down her bare thighs. The intensity of their eye contact was giving the brunette shivers. She could see the dilation of JJ's pupils and knew that she was struggling to maintain control. She slid her hands up again, deliberately letting her fingers brush tantalisingly close to the blonde's underwear.

"Emily..." JJ rasped.

"Yes?" the brunette breathed.

"Lick me"

Emily groaned loudly. Bet or no bet, she would never have been able to resist that command. She ran her hands up the blonde's thighs one more time, this time taking hold of the sides of her underwear and sliding them back down her legs. She licked her lips unconsciously at the sight of JJ laid beneath her, her legs spread as she awaited further contact from the brunette.

"Now" JJ ordered.

Emily leant down immediately and buried her face between the blonde's legs, lapping at the wetness that she found there. Both women moaned at the contact. In that moment, Emily was sure that she'd never tasted anything sweeter. She hooked her arms under JJ's thighs, lifting them in the air to give herself a better angle. This gave her the access that she needed to kiss the blonde's core with abandon, losing herself in the essence of JJ.

"Fuck, Em...you're so good..."

JJ flung her arms behind her head, gripping onto the arm of the couch. She could feel Emily's tongue beginning to make random patterns over her clit and the feeling was exquisite. Every so often the tip of her tongue would flick the sensitive nub and it sent a wave of pleasure through the blonde's body.

Emily smiled into the blonde's core as she heard the small gasps that escaped her lips. She dipped her tongue down and pushed it inside her, earning a loud groan.

"Oh god...fuck me with your tongue baby...just like that..."

The brunette stiffened her tongue and began to plunge it in and out of JJ. The blonde's hips raised to meet each thrust and Emily gripped tightly onto her thighs. The taste of JJ filled her mouth and she was desperate for more. Every time her tongue entered the blonde, it brushed over the most sensitive part of her walls and JJ moaned in pleasure.

Without warning, Emily withdrew her tongue and sucked the blonde's clit into her mouth. As she held onto the sensitive nub, she flicked her tongue over it's tip and felt JJ squirming beneath her.

"Oh my god...oh my fucking god..."

Emily was relentless, knowing that her actions were driving the blonde higher and higher. She reached up with one hand to cup JJ's breast over her top, squeezing it firmly as she increased the speed with which she was flicking her tongue.

"Don't stop Em, please don't stop!" the blonde begged.

Emily had no intention of stopping. She released the blonde's clit from her mouth so that she could fully use her tongue to lap at it at maximum speed. JJ's hips were rocking violently and her knuckles turned white as she gripped the couch arm tightly.

"Fuuuuuuuck!" she cried out as the orgasm washed over her.

The sounds of pleasure coming from the blonde caused Emily to moan against her core. She held onto her thighs tightly and continued to lick her clit until JJ finally stopped moving.

"Oh my god..." JJ whispered, her arm dropping to cover her eyes.

Emily knelt up, smiling at the reaction that she'd provoked.

"Come here" the blonde commanded softly.

The brunette willingly crawled up over JJ's body and settled into her arms. The blonde lifted the arm that was covering her eyes and gazed up at Emily shyly.

"Hey you" Emily smiled at her.

"Hey..."

JJ reached up to cup the brunette's cheek and pulled her down to press their lips together. They pulled apart slightly but kept their foreheads resting against one another.

"Em...I love you"

Butterflies filled Emily's stomach. Although she'd only heard the blonde say those words for the first time today, she was already sure that would never tire of hearing them. They made her heart feel so full that she feared it might explode. Well, not actually, she reasoned, for a moment imagining Reid's response if she'd told him that and all the biological explanations for why love couldn't make a heart explode. She laughed and kissed JJ softly.

"I love you too, Jennifer"

"Good" JJ smiled "because I think it's time I reasserted my authority"

Emily raised an eyebrow.

"Get your ass upstairs to the bedroom"
