A/N: Hi guys! Rizzoli/Isles is my new obsession, and actually my first same-sex ship AND my first true non-cannon ship, personally. If you're a hater, feel free to not read on. But if like me you are just waiting for that inevitable moment when our detective and doctor get together, read on! This particular oneshot was inspired by a scene from the first episode, when Jane evacuates herself to Maura's house, in hopes of avoiding a run-in with Hoyt. Just as she starts to get comfortable, that pesky FBI agent man comes a-knockin'...

What the—what on earth is that FBI tool doing here?

Not much time to dwell on the matter. When Dean glanced over at the door behind which Jane was hiding, she quickly pulled back. In the few moments it took her to tread lightly back to the bed, she realized instantly that she was overcome with jealousy, which was really weird. The jealousy wasn't so weird, so much as who it was aimed at.

Sure Dean was a nice looking guy, the type of man Ma Rizzoli had probably always fantasized about her daughter meeting. Any woman utterly confident in her heterosexuality would probably feel some natural jealousy towards her best friend who seemed to have had no trouble in getting this attractive guy to come to her house in the middle of the night. That wasn't what was happening here, though, much as Jane was scared to admit. She wanted Dean to leave. She wanted Maura for herself. What was this feeling? It had just crept up on her, out of nowhere. She'd known Maura for quite a while now and had never really felt so strongly towards her. Sure she was beautiful, successful, brilliant… maybe a little too literal now and then, but it was always surprising that she'd never found a man by now. No matter how dorky she claimed to be, Dr. Maura Isles was a catch. A hot, hot catch. And Jane, always one to listen to her gut feelings, knew right then she was jealous of that rude FBI agent.

She fixed a smile on her face when Maura re-entered the room, and actually it wasn't too difficult to grin: Maura had clearly arranged for Dean to come by, yet when she, Jane, had showed up instead, Maura didn't send her away. She didn't tell her she was being ridiculous, or that she ought to go back to her family. She put her in a bed… it was Dean she had sent off. Then she came and lay down on the bed next to Jane, seemingly oblivious of the nervous electricity her simple actions sent through the detective.

"So," Jane drawled in an effort to remain cool, "are we having a sleepover, or is this your way of telling me that you're attracted to me?"

Maura chuckled softly, and it sent a tangible chill through Jane. How had she never noticed what a cute, sexy sound that was? Maybe because she's never made it while we were lying in bed together in the middle of the night when she's wearing silk… yeah, that's probably it.

Instead of really answering the question, Maura said, "I'm not seeing him."

"Yet," Jane teased, trying to keep the conversation light.

Maura's gosh-awfully cute smile widened. "Somebody should, don't you think?"

"Yup." Short, non-committing answers.

"Should we draw straws?"

Counter with a crude joke: "What if we just show him our boobs, let him pick?"This earned her a whack with a pillow, and after the laughter subsided, Jane's curiosity got the best of her. "What'd he want?" she asked in another attempt to sound casual.

"I can't say," was Maura's terse reply.

"Fine. Go sleep in your own room."

"Jane…"

This was bad. Dozens of life-threatening situations had nearly sent Jane to the morgue, yet her heart had never hammered this hard; no moment had ever seemed to carry the weight of so much possibility…the possibility that she might kiss Maura right now and change their relationship forever… either for better or for worse. But she couldn't just make a move out of nowhere. Surely Maura didn't feel the same way, she just couldn't. It wouldn't make sense! Maura was so feminine, so quick to flirt with men, so open to inviting them over late at night for reasons she couldn't disclose to her partner and her alleged best bud.

Time for some detective work.

"Did you ever like the same guy as your best friend?" Jane asked, not sure where the words were coming from.

The response was immediate: "No."

"Did you ever have a best friend?" Jane asked, half jokingly.

Maura frowned slightly, and managed to say "no" without sounding sorry for herself.

Jane wanted to reply with something snarky, like, "You'd tell me if you were a Cyborg, right?" but the quickness of Maura's answers and the detached tone with which she said them gave Jane pause. "Aren't… I mean, wouldn't you maybe say—I think, Maura, you're my best friend. You're the best friend I've ever had."

It took an insane amount of self-control for Jane to keep herself from looking over at Maura, who she could tell had turned to stare at her. If she reciprocated the move, she felt there was little she'd be able to do to stop herself from grabbing the doctor's face and kissing her like a horny teenager.

"Jane, do you mean that?"

Already uncomfortable with where this was heading, Jane shrugged. "Of course."

"Well…same goes for me. I never thought I'd have someone in my life who gets me as much as you do."

Too bad for both of them that Jane was still determinedly staring at the ceiling. If she had allowed herself to look at the M.E., she would have probably noticed the way Maura was biting her lip and giving Jane a good-God-I-want-to-kiss-you gaze of desire. She was genuinely unable to tell if Jane was uninterested or just totally oblivious to (what Maura perceived to be) a completely blatant attempt to open a flirtatious dialogue.

"So if we're best friends," Jane said, "You wouldn't have a problem giving up that Dean guy for me?"

Fortunately Maura interpreted this the way Jane had intended it to sound, as opposed to the doctor thinking it'd mean "dump him and take me." With a laugh, Maura said, "You want him, fine! Take him!"

"Geez, talking about boys and all…this really is starting to feel like a slumber party," Jane remarked.

"I never got much sleep at slumber parties, ironically."

Oh, really? "Mm…yeah, girls rarely do. They stay up…doing other things…"

"Talking, mostly," Maura sighed. "Or playing stuff like Truth or Dare."

Jane couldn't keep a bark of a laugh from coming out. "Ha! Please! Playing that game wouldn't ever be fun with you, you always tell the truth anyway."

"Yes, which reflects a certain desirable moral standard, doesn't it?"

"Sure, or a sucky ability to lie."

Maura propped herself up on one elbow. "Okay, Detective Rizzoli. Let's play. Go ahead, truth or dare."

Jane smiled up at her. "Are you serious right now?"

"Does this face look like I'm joking?"

"It…okay. Um, dare, I guess."

I dare you to kiss me! I dare you to take your top off! I dare you to get out a pair of your handcuffs and—"Okay. I dare you to…to…"

Checking her watch, Jane could have no idea that Maura was scrambling internally for some kind of dare that wasn't so, well, daring. "Maura, come on!"

"I dare you to call Stanley and tell him what turns you on!"

"What! The mailman guy? Maura, gross!"

"You have to do it, I dare you! Don't tell me you're chickening out!"

"I can't, I don't have his phone number, unless you have it for some reason?"

"Jane, how many times have you called down to the cafe for something? Leave a message on his machine at work!"

With a slow smile, Jane pulled out her phone. "I have to say, I'm really surprised at you, Maura." She slowly dialed the number, chuckling to herself. "Damn, he'll probably recognize my voice."

"Well, I didn't say you had to sound like you."

"Mm, wish I could do a good impersonation of you," Jane said as the phone rung. "Oh, okay I got it." Then, in an eerily excellent imitation of her mother, Jane said, "Hi Stanley, you sexy mailman/kitchen worker you. I've been watching you and, truth is, I've been too shy to say anything to you in person, but… you are hot. You are one hot man, and you know what turns me on? Whipped cream. Where you would put shaving cream, so I could lick it…off… your face. And you know what else turns me on? Brains. Not, um, eating them, but people who have 'em. And I think you have 'em, Stan." She made the grand mistake of glancing at Maura, who was doubled up in silent laughter, forcing Jane to put her hand over the receiver so the machine wouldn't pick up her own giggling. "So—if you have brains you'll um—you'll"—more laughter—"Show up tomorrow outside Dr. Isles' office with whipped cream and a dictionary!"

She finally ended the call, no longer able to keep in the hysteric laughter. Maura was brushing away tears, though this didn't stop her from slapping Jane's head. "Outside my office? And with a dictionary?"

"I dunno why I said that, I panicked!" Jane laughed.

"Do dictionaries turn you on?"

"Hey, you gave me a dare, you didn't tell me I had to be truthful," Jane countered. "Oh, my gosh, I can't believe I just did that! How old are we, thirteen?" She started laughing again, simply pleased by the fact that she had given Maura so much amusement. "Okay, okay, now. It's your turn, doctor, truth or dare?"

"Truth."

"Aw, come on, Maura!"

"Truth! Go on, ask me anything you want!"

Slightly disappointed but not surprised, Jane gave Maura a good looking-over. "When's the last time you told a lie?"

It was Maura's turn to avert her gaze. "You're gonna laugh at me."

"No I'm not."

Sigh… "Tonight."

"Tonight? It wasn't to me, was it?"

"No, it was to Dean." Maura glanced over at Jane, who could not disguise a look of deep curiosity. "I mean I didn't say an outright lie, I just wasn't completely honest with him." She could feel herself turning red under Jane's deeply interested gaze, and quickly said, "I'm not telling you what I said, though, you didn't ask that! Your turn again, truth or dare?"

Jane narrowed her eyes, feigning an annoyed look. "Truth."

"Learned your lesson, hm?" Maura laughed softly. "Okay, truth… truth. What do I most want to know about Jane Rizzoli?" What would you say if I asked you to kiss me right now? Have you ever made out with a girl? How come you're still single? "Oh, I know. What did you think of me the first time we met?"

With a good-natured groan, Jane rolled onto her back. "Geez, Maura! I dunno!"

"Yes you do, no more stalling."

Jane continued to stare up at the ceiling, her expression slowly softening. After a few moments, she spoke in a reverent tone: "I remember feeling a lot of things at once. My very first, honest impression of you was that you were the most beautiful woman I had ever seen." She forced herself to speak clearly and not too rushed, because otherwise the comment might sound too gay. This was supposed to come off as objective. Straight. "Part of me was surprised that—I mean, that someone who looked like you could be a medical examiner."

"What's that supposed to mean?" Maura asked, albeit in a teasing tone.

Furtively glancing at her, Jane shrugged (or shrugged as best she could while lying on her back). "C'mon, Maura, I'm sure most doctors don't spend as much time fretting about fashion as you do, or come to the door in the middle of the night looking as though they had just left a photo shoot."

"You know, that's a stereotype grounded in absolutely no level of reality," Maura said very matter-of-factly. "Regardless of their looks, people have inherent interests with which they are born, and frequently cultivate said interests as they grow older. Mine happened to be science, medicine. It doesn't matter that I was often told I should go into acting, or modeling, or whatever just because I was good-looking. It's not what I wanted to do, it's why I didn't follow up with ballet. I've always wanted to be exactly where I am now." Next to you, in bed.

With a smirk, Jane asked, "Are you saying you know you're gorgeous?"

"Yes. But it shouldn't be surprising that I'm a medical genius, also."

"Oh, you are too…too precious," Jane chuckled.

"Well I had the same feelings about you, too, when I met you," Maura said, causing Jane to perk up slightly. "You didn't look the way I expected a female cop to look, even if you did seem kind of hard at first."

"I can be soft…on the right occasions," Jane said in that husky bedroom voice of hers that turned Maura on so much it frightened her. She caught Jane's eye, and saw Jane's gaze drop briefly to her mouth. It seemed Jane sucked her cheeks in slightly before looking back into Maura's eyes once more. "Okay, your turn again. Truth or dare?"

She spoke with almost a whisper: "Dare."

Just then, a small clunking sound came from the kitchen. Jane sat up abruptly, her heartbeat soaring; it all came back to her. Yes it was terrifying being in bed with Maura, but that was a thrilling sort of terror that excited and aroused her. Outside of this room lay a much more life-threatening horror, a psychotic man out to get her. That's why she was here, that's why she was with Maura… Hoyt was after her, he wanted her dead, or at least he wanted her. Every nerve was pulsing with fear, and even as she knew it was more than logical for her to be afraid, at the same time she hated for Maura to see her like this.

But then Maura's hand was touching her arm, her bare arm exposed by the sweater that had fallen slightly with the haste of Jane's shift in position. The doctor's fingers smoothly rubbed Jane's arm as she whispered in a voice like a caress itself, "It's okay, Jane, it's just Bass." And Maura hated herself for thinking how particularly beautiful Jane looked when she was afraid, maybe because it was an expression she so rarely saw on the detective—who, at this moment, still looked petrified. "Really, Jane, it's all right…"

After a few moments, Jane was calm enough to lay back down again. Before she had time to process it, she admitted quietly, "I've never been this scared in my whole life." She wore an adorable, nervous smile, and without thinking, Maura kissed it.

She had shifted herself so that one arm reached over Jane, while her wavy blonde hair fell like a curtain on the left side of her face. The move was pure instinct: Jane was scared, she needed to feel protected and cared for. Loved. What better way to do that than with a kiss? The very moment their lips met, both women felt as though they had gone into cataclysmic shock. How could something as simple as a kiss feel so…good? No, "good" wasn't giving it enough credit—to Maura it felt better than winning the Nobel Prize, and to Jane it was making a home run, catching the crook, and beating her brother at hoops all rolled into one. It was sexy, it was scintillating, it was enlivening. It was the class and sentiment of Dr. Isles; the passion and energy of Detective Rizzoli.

All this in a kiss that lasted less than three seconds. Maura pulled away, suddenly embarrassed, but Jane immediately reached out to bring her back, cupping her face with her calloused hands. The kiss was more intense than the first one, probably (she thought) because she had initiated it this time. She was relatively gentle, but this passion she'd never known she was capable of possessing was forcing her to move Maura onto her back. But this move made it difficult for her to put her arms around the doctor, to really hold her close, and that was what Jane realized she most wanted. As if reading her thoughts, Maura pulled herself up, still kissing her partner, by gripping Jane's arms and sitting up.

They broke apart and Jane clung Maura as close to her as she could. She was trembling with disbelief at what had just happened, at its possible ramifications, but also because she was still terrified of Hoyt. "Please, Maura," she said in a broken whisper. "Stay with me tonight, I c-can't be alone."

Maura's fingernails briefly dug deeper into Jane's back, and she tried not to let herself get distracted by Jane's (surprisingly) sweet-smelling hair—a difficult task, as Maura's face was practically buried in it at this point. "Jane," she said through her teeth. "I… don't…"

She could feel Jane's shoulders droop, but their embrace remained tight. "You think that was a mistake," Jane muttered.

At this, Maura pulled herself back, keeping her hands on Jane's arms. Jane was staring at a spot on the bed, embarrassed with herself but also confused, as Maura had been the one to kiss her. She curled one hand into a fist, and Maura reached out to clasp it with one of her own hands.

"I don't think this is a very good idea," Maura said thickly, despite how much she had wanted it to happen and how wonderful it had felt. "We work together, Jane, we're partners. You're my best friend."

"I love you, Maura," Jane said flatly, looking up at Maura and studying her face for the slightest clue of her true feelings. "I thought I loved you like the sister I never had, but it hit me tonight, I want you. I can't help it."

"That was my first impression of you," Maura said, tearing up. "Not that—I mean, my first impression was that I… wanted you." Maura felt like she was walking on air when Jane slowly smiled at this, but when the detective leaned in for another kiss, Maura pulled back. "Jane, it's just… you want to know the numbers on how relationships turn out between co-workers?"

"Not good, I'm guessing," Jane said.

"Very not good. Bad, even. Horrible."

Jane gave a small grin, fully aware that Maura was still flustered and pleased that she'd had this effect on her. But the smile faded as she interlocked her fingers with Maura's, and looked into her eyes again. "Your statistics tell you that being with me is a bad idea. Okay. I understand. But tell me what your gut says."

"We've been over this, Jane. I have hard time going on my gut feelings—"

"I dare you to."

It took a moment. Then Maura finally returned Jane's stare, and upon seeing the hopeful smile on the detective's face, Maura realized what that sentence meant.

"I dare you, Maura Isles, to go with your gut on this one."

This was a look Maura knew well. Jane had only ever used it on her… so many people only knew Jane Rizzoli as a hard-as-nails cop, or a sassy woman who won't take your B.S. So precious few had witnessed her softer, kinder moments, such as when she was comforting a victim's family or trying to talk an overemotional suspect into calming down. She was never patronizing, never violent, never angry unless the person really, really deserved it. Yet here was this look, unlike any other in Jane's arsenal of expressions, reserved specifically for Maura, and it was only now that the doctor really appreciated what it was intended to convey. It meant this woman truly loved her like no one else. It meant every kiss, every flirtatious word or gesture exchanged with a man had only been a step to bring her closer to being with Maura. It meant Jane never wanted her to feel alone. It meant all the logic and all the stats and all the worries were pointless, completely futile. It meant Jane Rizzoli wasn't going to let anything stand in her way anymore of being with the one person she could not live without.

"Well," Maura said after a long pause. "If you put it that way…I guess the choice is out of my hands."

And she smiled that too-familiar, too-endearing smile that Jane adored so much, with deep-set dimples and brown eyes shining brightly. They met in a kiss, less scorching than before and somehow more intimate for it. Jane could not believe that mere moments ago she had been drowning in nothing but fear, and here suddenly she was the most happy she had ever been. She almost didn't care if Hoyt found her now because she could die happy, without any regrets …but fortunately, the prospect of living out a long and healthy life with Maura Isles was more than enough of a reason for her to keep on fighting. So she vowed she would.

A/N: More to come, hopefully soon. Reviews are always appreciated!
