A/N: I wanted to wait to write this one after the season finale, in case for those who didn't know that Riley was a cop, I didn't want to spoil it. I figured she should make an appearance somehow, especially since she's Jane's neighbor lol. Now I know this chapter may be a little different, I'm still debating whether I actually like it or not, I hope you'll enjoy.

Chapter 4

"Look, I know Frostie hate me right now but I'm hoping to make it right in some way. I really want to make it work on homicide." Riley speaks with Jane and Maura in Maura's office.

"Frostie?" What the hell is Frostie? Jane looks at Riley and Maura trying to figure out what she missed.

"Yeah." Riley stares at Jane with curious confusion. "Ain't that the nickname that Frost and Frankie has goin' around? That's what the guys at the department call them."

"Oh, I've heard about things like this. They've been shipped, correct?"

Jane rolls her eyes as what she was sure to get some form of history lesson. "What?"

"Shipped. It's deprived from the word relationship, belief that two characters, fiction or non-fiction, are in a imtimate relationship, have romantic feelings that can form into a relationship, or another form of a less imitate relationship, such as a platonic friendship, or even violence. In their case, they would be considered slash-"

"Please tell me the rumor relationship is just platonic." Frankie and Frost? No way. I mean, their just friends. Right?

Riley shrugs while grinning at Jane and Maura behavoir that she tend to find so amusing. If she didn't ask Frankie and Frost weeks ago, she would have sworn they were a couple. "Last time I heard, unless you heard something different."

Maura looks at Jane with curiostity. "Do you read fanfiction?" Jane just shrugs so Maura turns back to Riley. "Why don't you come over for dinner? We'd be interested to get to know you futher as you are now apart of the homicide team." She was asbolutely oblivious to the glare that was sent her way.

"Sure. I'd love to." She grins at the beautiful doctor, before leaving the office...

"This meal was delicious Dr. Isles." Riley smiles, taking a sip of the beer she had with her meal.

"Well thank you Detective Cooper. And please, call me Maura."

"Only if you go back to calling me Riley."

Maura sends a flirty smile back in return. "Fair enough." She gathers the used dishes off the table before

"Hey." But before Jane could give a response, she sees the sexy knew neighbor on the couch with a beer. The same beer that she noticed that Jane drinks. It was making her feel uneasy.

Maura steps out from the kitchen to see Marisa standing at the door and smiles. "Oh, hello Marisa."

Marisa awkwardly smiles back. "Hello Dr. Isles. I hope I'm not interrupting-"

"Ofcourse not, we were just about to have dessert. Join us?"

Marisa glances at Jane briefly before looking back at Maura. "Um, sure. If it's okay."

"Ofcourse it is."

Jane trying not to be awkward, but failing, guestures her inside."Yeah, come in." She inhales the fresh scent of Marisa's body wash as she walks past. Warm Vanilla Sugar.

Riley gets off the couch and strolls over to the slightly younger woman. "Hi, I'm Riley. I live right across the hall." She extends her arm out for a shake.

"I'm Marisa. I live right below." Marisa shakes her hand with a warm smile.

"Yeah I know, I've seen you around." Riley responds with a flirtatious smile. "You're the lawyer girl right?"

Marisa blushes and looks away avoiding contact. "Yes, I just started at the Lehane Law Firm. I'm hoping to one day to become a DA."

"DA huh? You look too adorable and sweet to be a DA. Maybe we'll see each other more often when that happens though." Riley steps a little closer to Marisa, beer in hand.

"You're a lawyer too?"

"Detective. Homicide." She flashes a winning smile, knowing her confidence and her job occupation would most likely be a turn on.

"You too huh." She smiles back as looks over to Jane, and becomes tense seeing irritated glare thrown in their direction, her smile fading away. She looks back to Riley, finally noticing the tattoo on her body. "You're body art amazing."

Riley raises an eyebrow and licks her lips slightly. "You think so, huh?"

Maura interrupts the conversation briefly, seemingly oblivious. "Would you like beer or wine? I'm serving creme brulee."

"Wine please." As Maura retreats back into the kitchen, she couldn't help but feel quite uncomfortable while getting checked out by the tattooed detective, while the detective she's been sleeping with is standing right there watching their every move. Maybe this wasn't such a good idea...

Fuckin' Bullshit! Her mind was screaming over and over again. Marisa and Riley had just left a couple minutes ago, with the latter offering to walk the former back to her apartment. The constant flirting from Riley was getting to her, and now who knew what going on just one floor below.

"Jane are you okay?" Maura's gentle hand comes to the other woman's shoulder from behind in the kitchen.

Jane continues to avoid Maura's eyes, knowing she could read her like an open book. "Waht do you mean?" She pops open a fresh beer before taking a gulp.

"You just seemed uncomfortable the whole night. I was hoping the drinks would loosen you up a bit, but it seemed to escalate when dessert came. Was it wrong to invite Riley over for dinner?" Maura had a feeling that maybe she shouldn't have just invited Riley over to Jane's for dinner without talking with Jane first, especially since she didn't even live there.

"No. No, Riley's cool, I guess. You were right to invite her over. I need to get to know her especially since not only do we work together, we live right across and she has an interest in my brother as well as my partner." She turns around to face Maura, taking another sip of her beer.

"I actually believe she might be bisexual." Maura drinks her wine with a smile.

No shit. "Really? How the hell did you pick that up?" Was it the fact that she was flirting with you half the night, or was it because she was practically drooling all over Marisa the other half.

Maura licks her lips, displaying her dimples, waiting to share her secret. "I believe I've seen her quite overly flirtatious with Senior Criminalist Susan Chang a few times."

"Explains why she's so quick to head to autopsy every chance she gets. I swear she's always down there."

"Well, you're always down in autospy." She raises her eyebrows at the irony of the conversation with amusement.

Jane becomes slightly defensive. "I'm getting results in cases as while chatting up my best friend."

"And she's getting results on her cases while possibly testing out the potential of a possible mate."

Seems to me she just wants to fuck everyone that moves. "Right. Well, she can do that shit her own time if you ask me."

"You mean like with her with Marisa?" She watches Jane closely as she refills her glass of wine.

Jane casually averts her eyes fromt he other woman, knowing she was trying to read her. "What do you mean?"

"They'd seem to be quite comfortable with each other tonight. Not to mention , they'd shown signs of having interest in each other sexually."

"Thank you Maura for the informantion." She simply downs the rest of her beer, becoming agitated by the second...

Two hours later, she couldn't take it anymore. She couldn't believe she was standing in front of Marisa's door, smoke ready to blow out of her ears. But she had no right. Marisa was free to do what she wanted. They'd been putting it off for so long, but now, it was time that they had that talk. So she knocks, hoping that Detective Cooper was nowhere in sight.

"Jane? Is everything okay?"

She didn't know how to respond. She wanted to get mad, maybe even yell little, but she knew she had no right. They were just friends. Friends that were sleeping with each other.

She takes a deep breath to calm herself. "You know, if you want to date Riley, let me know now."

"Come in." She waits for Jane to cooperate before checking her the hallways to see if the coast was clear and shutting the door. She turns to Jane, holding her robe closed. "What do you mean?"

Jane shrugs her tense shoulders, trying to stay calm. "Just seems like you two really hit it of tonight."

"Jane." She goes over to the couch to sit down, knowing this might take a while. She could sense the jealously already. Hell, she sense it all night.

"No, let me know, so we can stop whatever we've been doin'." Her voice for a moment falls into a whisper. "Did she kiss you?"

"Jane please-"

"I mean 'cause if that's what you want, go for it. It's not like I made you my girlfriend." She looks away from the beautiful sad brown eyes, feeling pain to even look at them.

Marisa's own voice turn into a whisper. "No, you haven't."

The edge of jealousy comes in her voice as it a raises. She didn't want the conversation to go like this, but she couldn't help it. "Yeah, I know we never really talked about what's goin' between us but damn, did you really have to put it in my face like that? 'Your body art is amazing'. Really? Give me a fuckin' break."

"Me?" Offended, Marisa stands up from the couch, anger now rising from her. "Me puttin' it in your face? Coming from the woman who spends her time looking at her best friend like she's the most special person in the world. This beautiful, incrediably intelligent doctor who understands you. She's probably in your bed right now, probably woke up because she's wondering where the hell you went." Just at that moment, Jane's phone goes off. As she reads her new text message, she couldn't stop the guilt spreading across her face. "How the fuck am I supposed to compete with that?"

"This isn't a competition 'Risa." Thick emotion sweeps her voice, making it crack a little. "You wanna know how I felt tonight? Yeah, I was blown by my best friend and Riley flirting before you even got here. Hell, I hate pretty much every suitor she has. Shitty track record with them, that woman has." It was now or never. There was no turning back. She walks over to Marisa, staring deep into her eyes. "But when Riley set her sights on you, it felt as if my girlfriend just dumped me for a younger and cooler model. I know I have no right to be upset, but I am. Can't help it. So now I'm figuring things out. Figuring out what I want."

The close proximity of Jane's presence was making her sway a little. "What is it that you want?"

"I want you." With that she grab the younger woman's face, giving her a deep "Just you." Another kiss. "I'm here taking what, I'm hoping, is now mine, and no one eles'."

"If this is your way of asking me to be your girlfriend," She hesitates, searching Jane's eyes to see if she following her correctly, before blushing a little with her smile. "Then I accept."

"Good." With that, she lifts her up into, knowing Marisa legs were going to wrap around her, their lips crashing into each other with more than just waves of lust. She quickly guides them into the bed, trying not stumble over books scattered across the floor, falling onto the bed, their kissing never breaking.

Their bodies moving into each other, touching every part of each other. Jane finally lift up, taking her removing her shirt, along with her bra. Marisa's immediately latching onto her breasts, recieving a moan from the older woman.

"Jane, I want your pussy on mine so badly."

Jane groans loudly, turning her on even more at the sound of the dirty talk. At the sound of hearing Marisa not being afriad to tell her what she wants. She begins kissing up Marisa's torso, removing her shirt in the process.

"Jane. Now."

She kicks off her boots, unbuckles and slips out of her jeans, before completely sliding her body on top of the younger woman. They both moan at the contact of each other's wetness. Marisa spreads her legs wider, bringing her knees back to her chest, resting the heels of her feet on Jane's lower back. Jane adds pressure of her pelvis into Marisa and begins rubbing herself onto her. It reminded them of their first time together, but at this moment, it felt so different and they didn't mind.

"Fuck. You feel so good." Jane moans in Marisa's ear, kissing her neck, inhaling the lingering scent of the body wash she smelled earlier.

Marisa grabs fists full of Jane's dark wavy hair and tugs hard. Jane knows what she wants to really do, dig her nails into her back, but she's holding back. She seen Marisa's guilty face after they have sex, seeing the long, stinging mark going down her back, but never said anything to reassure her. Jane loves the fact that she can bring her to such a sexual high that she herself would recieve pleasurable pain as a result. Just the thought of it was making her rub faster.

"God Jane." Marisa's hips buck into her rapidly, as her elbows dig into Jane's shoulder blades, bringing their bodies closer. Her hold on Jane's hair becomes tighter. The sounds of the slickness of their wetness coming together and the smell of their sweating bodies filled the room.

"Come on, do it. You know you want to." Jane's low voice makes Marisa's body shiver. The older woman begins sucking her neck, never slowing the rhythm of her thrusts. She was ready to cum, and feeling the aggressiveness of her lover and hearing the moans passing the full lips, the younger woman was about to cum as well.

Marisa leans her head foward, collecting Jane's earlobe between her teeth. Her fingers slide out of Jane's sweaty hair, slide over her slick shoulders. Her body was beginning to

"Come on baby, do it. Fuck, I'm about to cum." Jane's own body begins to tense, her lips again attach themselves onto her lover's neck, and her thrust going hard and faster, ready to explode.

Marisa's body shakes uncontrollably and her teeth clenches into Jane's ear, her claws dragging down her back, her heels digging in her back and her toes curling. Jane hisses, arching her breats into Marisa. Both of their thrusts begin to slow down, until they finally collapse in sweaty heat.

"How's my girlfriend feeling?" Girlfriend. Jane couldn't help but feel a little giddy about what went down. She ended up getting this young, gorgeous, heart warming, intelligent woman to be her girlfriend.

"So good." Marisa softly runs her finger tips along Jane's tender back, thinking about everything that happend that night. "I can't believe we're actually doing this."

Jane lifts up to look at Marisa with a chuckle. "As apposed to the random, occasional, hot and sweaty, unspoken sex?"

Marisa laughs herself at the absurdity of it all. "Touche."

Jane, still smiling, looks at the younger woman's neck, noticing multiple dark bruising. She's never giving Marisa a hickey before. She now marked her territory, finally and she couldn't wait for Riley, who'd most likely try to chat up Marisa tomorrow, to see that she's already been claimed. You snooze you lose.

But then realization comes into play as she continues to feel the feathery soft tips of Marisa's fingers along her stinging back. Tonight may have been the first time she's branded Marisa, but the woman, who she's now made her girlfriend, had left her mark long before. Not only did she not mind, she wonders what too herself so long.

A/N: Added a little Frostie in the beginning lol. But anyways, I wanted a slight change in direction but I hope the chapter was good enough. I don't know how I ended up making a somewhat actual story out of a series of smut fics lol. I didn't really proof read it thoroughly so if there are any mistakes, let me know so I can correct it.

A/N: Don't worry, the steamy sex scenes are still in play now that they're in a relationship. I already have an idea for the next chapter, and I think that one might get quite interesting ;)...
