AN: Today's instalment is brought to you by severe exhaustion and agonising back pain. On the brighter side, were half way through people! Remember always open to suggestions, you only need ask. I did a little reading prior to this chapter and I've tried to keep it in the realm of reality, but having actually not achieved this you'll have to let me know how I did.

December 12th

Jane lay in bed that morning going through her emails on her laptop, Maura lay wrapped to her side idly drawing patterns with her finger on the detective's stomach. Satisfied that there was nothing particularly urgent in her inbox she closed the computer and put it to the side.

"So, any plans for today?"

Maura yawned lightly, "I do need to go shopping for an outfit for the Christmas party, but that can wait till this afternoon if you don't have anything pressing to attend to."

Jane grimaced slightly, "I had almost forgotten about that. Nothing says festive fun than a room full of people that are hard to stand even when sober."

"We don't have to stay all night, besides you still have fun with Frost and Frankie." The brunette grumbled as she shuffled down into the warm sheets and buried her head in the crook of Maura's neck. "Of course we can always leave a little early and have some fun of our own when we get home."

The detective smiled against the warm skin as she placed kisses to the affirmative wherever she could reach. "Why wait?"

"I must say Jane, I have found you exceptionally agreeable these last few days. I can't possibly imagine why." Her hands tangled in dark tresses as she basked in the attention. A sharp gasp turned to happy hum as a scarred hand massaged her breast, rolling her stiffening nipple between her fingers.

"I don't know what to tell you, perhaps I've found my Christmas spirit. Or perhaps I found this,"

She continued to lavish her attentions to the particularly sensitive skin behind the blondes ear as she placed today's box on her belly. Inside the box was another vibrator, but this one was long and slender with what looked like a small egg at the top. Maura smiled.

"Tell me, in your experience, have you ever ejaculated when you climaxed?"

Jane looked up, "You mean like squirting?"

"I believe that is the colloquial term yes."

"I can't say I have, besides isn't that just some porn trick or something?"

"On the contrary Jane. It can be done, but it doesn't seem to be a universal trait. Some women can, some can't."

"Maura, if I didn't know you better that sounds like a challenge."

"Think of it more as an experiment, after all failure is always an option." She tried to wiggle her eyebrows for effect.

"Ok we need to work on your sexy talk. I was right there with you until you quoted the Mythbusters!"

Maura didn't even try to hide her giggle, but she was happily interrupted by Jane's lips on her own. The detective's hand lowering, giving her hip a gentle squeeze as she passed. Trailing her fingertips through her trimmed curls, the blonde's moan stifled by their kiss. Reaching lower she cupped her hand over her core and was met with an abundance of wetness. Coating her fingers she lightly teased her opening.

"So doctor, talk me through the science bit."

"Y-You need to make sure that there is plenty of lubricant first,"

Dipping her fingers lower she gathered the moisture on them as she drew large lazy circles around her clit. Her hips pushed her closer of their own accord,

"Oh I'd say there was plenty of that yes,"

"Apparently the problem most people encounter is not being able to find or properly stimulate the g-soooo oh!"

Having slipped daily into her folds Jane zeroed in on one of Maura's weak spots with practised ease. A little way inside she coaxed her fingertips up and stroked the spongy spot on her walls.

"How does the egg on a stick help with all this,"

"Use it to, hmmm yes, use it to replace you fingers."

Shifting so that she was sitting between Maura's legs she turned the toy on to a lower setting. Coating the larger end in her abundant wetness she lifted it to softly tease her pulsing clit. Her happy mewling causing her own arousal to skyrocket. With little pressure she slipped the toy between her velvet folds having to estimate rather than feel the spot she was looking for.

In a few seconds of gentle movements Maura's hips jerked upwards, "That's it, there! I need a bit, a bit more,"

Without a word Jane dialled up the vibrations, happy she was heading in the right direction as the blondes head hell back.

"Talk to me Maur, what do you need?"

"H-Harder, not deeper."

With shallow movements she rubbed the toy over her g-spot with an added force but careful to not hurt her. Maura could feel a pressure inside beginning to build, her heels digging into the bed as all her muscles felt taut. She reached her own manicured hand down her body, jumping at her own touch on her sensitised clit.

Jane watched on with excited eyes, safe in the knowledge that even if she couldn't make her squirt, the blonde was still having a damn good time. Her fingers gliding over her nub with an incensed pace. A quick thought passed through her mind, without stopping her movements, the detective reached into the nightstand retrieving the small candy cane esk bullet she had used when Maura was away.

Coating the tip of the toy in Maura's own juices she attempted to properly lubricate it before turning it on high. The doctor cried out in the room when the powerful vibrations took over from her own fingers. Her hands shot to either side of her grasping at the bed sheets. Her hips bobbing clear from the bed.

"Keep going, oh god keep going! Oh fuck! When, when I say so, take out the wand,"

She nodded enraptured by the sight before her. She flicked the bullet over her straining clit flowing every movement of her hips, not allowing the sensations to cease. The pressure Maura felt in her grew, her orgasm just teetering on the edge. She tried every trick she knew to stave it off, to just keep going that little longer. Jane had long stopped asking her what she was saying when she tried to recount the periodic table. Her knuckles were going white with the grip on the sheets, her thigh muscles straining as she locked her legs, thrusting to meet the vibrations on her and in her.

It was beginning to get too much, her walls twitched lightly, every part of her drawn tight like a bow string,

"Now Jane! Nowoooooooh fuuuuuuuuuuuck!"

Feeling the urge to bear down she did so, the euphoric feeling of every muscle relaxing at once as liquid heat flooded from her. Her body shook as the deeply pleasurable waves of her climax rushed through her body. Her eyes rolled back into her head as her lids fell. An all encompassing warmth surrounded her.

Opening her eyes she found herself wrapped in Jane's strong arms back under the comforter. A mess of sheets sat crumpled at the foot of the bed. She felt a finger under her chin tipping it up, warm dark eyes met her own.

"Hey you,"

"Did I pass out?" Maura asked incredulously, that had definitely, categorically, never happened before.

"Just for a little bit, I didn't want you to get cold, so here we are. How you doing by the way?"

"I am doing amazing," she nuzzled into the warm skin under her cheek.

"So, has that, erm, ever happened before?"

"No,"

Jane's eyebrows shot up, "Really? I don't mean to sound so surprised, but you seemed pretty knowledgable on the whole thing."

"It's one thing to know the theory of something, another entirely to actually do it. I mean I wouldn't expect to be able to drive a car straight away just because I had read a book about how."

"I bet you did though,"

"So that isn't my best example, what can I say Jane, you just short circuited my brain. You can't expect me to fire on all cylinders after that."

"I'm just happy your experiment was a success."

Slipping out from the warm embrace she moved on top of the brunette.

"Now Jane, what kind of scientist would I be if I relied on only one result? Solid conclusions can only be drawn from multiple tests,"

Leaning up she dragged her tongue from a pronounced collar bone up her neck to nibble on her ear lobe.

"God I love it when you talk dirty to me."
