AN: For the purpose of this story, Casey does not exist, at least not the way he did in the show. I know that the episode I used as reference (Over/Under) contained a lot of Casey and Jane worrying over his surgery, but that's not what I wanted to happen in my own Rizzles world. Also, this chapter is bordering on M rated, so be forewarned.

About 3 1/2 Months Ago

Maura got Jane another beer from the refrigerator and took one for herself. After the softball game, she felt so much more like everyone else than usual and she wanted to keep that going. She was also thrilled to have made up with Jane after their silly fight. Her best friend was the one person in all the world to know everything about her and love her for who she was. Jane didn't care when Maura rambled on with facts about everything, even though she found them useless. Jane found it endearing that she didn't always understand slang or figures of speech and took everything literally. Even when Jane poked fun at her for never guessing or lying, for dressing up in designer clothes, and for her pretentious childhood, she knew that her best friend accepted all of those things about her. Even when it came to her darker side and her struggles, those things she rarely showed to anyone else, Jane understood. Jane was the one person Maura could count on and always be comfortable with, but when they fought, it felt like her world was crashing down. Maura Isles liked order and she loved Jane Rizzoli. She needed her world to stay intact.

She joined Jane on the couch and they drank and laughed about the game and everything felt really lighthearted and good. They both drank quite a bit more than was common for them. At some point, Maura had stretched her legs out on the couch and rested her thighs across Jane's lap. Jane's hand ran mindlessly up and down Maura's thighs. Maura felt very warm at the contact and suddenly felt the need to strip out of her dirty softball clothes and get as clean as possible. She stood. "I'm going to take a shower."

"Maybe I should join you." Jane spoke so quickly that Maura was sure she'd misheard.

"Wh-what?" Maura stammered.

"In the shower. Join you." Jane's words were a little slurred from the excessive drinking, but the look in her eyes was one Maura recognized. She'd seen it in the eyes of men when she walked by wearing something a little tighter or more revealing than usual. The look was pure lust.

It made Maura come undone. She stripped down to her sports bra and spandex workout shorts. She searched for any change in Jane's dark eyes, but if anything, they only looked hungrier as they looked her up and down. This kind of response from her best friend was something she'd been waiting for longer than she'd like to admit. She'd spent years toeing the thin line between best friendship and something more intimate, patiently looking for any sign that Jane had finally seen what she knew was between them. Maura took this chance to make an even bolder move. She went back to the couch, putting one knee on either side of Jane's legs to straddle her lap.

"Maura..." Jane trembled as she spoke.

Maura had never been so turned on in her entire life, simply by sitting on her best friend's lap and hearing the way she said her name. She put her hands on either side of Jane's face and leaned forward until the top halves of their bodies were pressed against each other. She kissed Jane, gently at first, but then harder, slipping her hands back onto her head. She yanked softly on the ponytail holder until dark curls fell around Jane's shoulders and she tangled her hands in messy hair.

Jane's response was more than she could've hoped for. She returned the kiss with so much desire, it felt like she needed to taste Maura like she needed oxygen. Their tongues were in each other's mouths and Maura got such a high from the lightheaded feeling of not stopping to take a breath. Jane's hands traveled to the back of her shoulders and down her bare back, coming to rest on her waist. Maura took fistfuls of Jane's T-shirt in her hands and pulled up, forcing Jane to lift her arms to allow the shirt to come off. Maura then placed her hands over Jane's flat stomach, the tips of her fingers sliding under the bottom of a black sports bra. She thrust her hips forward just enough to elicit a moan from Jane.

Jane's hands gripped Maura's thighs hard just above her knees and then slid them upward and the sensation on her bare thighs brought something out of her that was more dominant than she knew existed. She lifted herself off of Jane's lap enough to grip the other woman's thin shoulders and maneuver her until she was lying back on the couch. She stood and pulled red athletic shorts over Jane's hips and down her long, tanned legs. Jane wore simple cotton underwear, bikini cut, and black to match her sports bra.

Jane grabbed Maura by her spandex shorts and pulled her onto the couch. Maura mounted her best friend, keeping one thigh pressed between Jane's legs. She felt Jane's thighs tighten around hers and the unmistakable dampness soaking through black underwear caused Maura to release a moan of her own. She raked her fingernails lightly up Jane's sides, content with the goosebumps she caused despite the warm temperature of their bodies. She lowered her entire body onto Jane's and bare skin met bare skin as she nibbled at Jane's throat before finding her lips once again. After a moment of ecstasy in exploring the inside of Jane's mouth with her tongue, Maura pulled back slightly to take a breath. "I can't believe we're finally doing this," she sighed, before leaning in for more.

That's when she saw it. The change in her best friend's eyes. They went from shining with need to dark with confusion in the instant she registered Maura's words.

"We can't." Jane sat up the best she could, the sudden movement knocking Maura to her knees on the floor beside the couch. Jane didn't miss the hurt suddenly all over her best friend's face and she was filled with something akin to regret, but the damage was done.

Maura picked herself up off the floor, embarrassed and refusing to look at Jane. "I'm going to take a shower," she mumbled. She grabbed clothes off the floor and practically ran out of the room.

It was only later that Maura realized she'd grabbed Jane's softball T-shirt rather than her own clothes. She put it on after her shower, despite the fact that she was now clean and the shirt was covered in dirt and sweat and smelled like Jane's vanilla body spray. She went back to the living room, armed with an apology, but Jane was gone. Maura knew then that nothing would ever be the same.

A/N: I thought you all deserved something a little smutty after sticking through so much angst. There will be plenty more of both to come. Thank you for reading and please review!
