A/N: Hello all. My apologies for such a lengthy time until an update! I was really struggling with where to go with everything. Now, fair warning, we have some sidetracks but there will be Rizzles, I swear! I hope you all just hold out hope and enjoy the chapter? Please leave feedback either way! Hugs and love!

When she went home that night, it took everything inside Maura Isles not to scream. How could the object of her affection go off with another woman? It was all very real and she couldn't ignore it any longer. Top that with the growing suspicion she had that Kate did in fact fancy Jane as well. It just all felt like too much.

But, she was not one to scream. She went to the kitchen and poured herself a glass of wine and began heading toward the stairs. A nice, hot bubble bath and good cry would suffice. That was until an unexpected knock interrupted her plans.

She wandered over to the door, wine glass still in hand. She checked through the privacy hole first, shocked at who was on the other side. "Caitlin," she said as she opened the door. "Is everything alright? You don't usually stop by without calling." Maura's voice was gentle yet held concern.

As her sister opened the door, Kate's eyes were wide and glued on the dress she was wearing. "Maura! What are you wearing!" Was all that could come out as she went into her sister's house.

The question at first caught Maura off guard until she looked down and remembered she was still in the dress from the Merch. "Oh," she blushed. "Jane and I did the undercover operation. This is what the waitresses at the Merch wear," she pointed out.

"So you dressed like that all night in front of Jane and a bar full of lesbians?" Kate's voice was filled with a tone Maura couldn't place right off.

"Yes. That is the point of being undercover. Would you like to come in and have a glass of wine?" She asked as they both seemed to be heading toward the kitchen.

Kate nodded. "That sounds nice. Um, nothing was wrong. I'm sorry, I should have phoned. I was just taking an evening drive. Jeff is doing work at home and the kids are asleep."

Maura reached for another glass and pulled the bottle she'd opened out of the fridge. "I see." She handed the glass to her sister.

"Thank you," Kate smiled. They sat at the island sipping their wine in silence for a few moments. "How was it?"

"How was what?" Maura looked at her sister, slightly confused.

Kate motioned to the dress Maura had on. "Looking like that in a lesbian club?"

Maura thought before speaking. "I don't really have anything to compare the experience to. I've never been a partying person. It was noisy but everyone seemed like they were having a good time."

Kate waved her hand. "Maura, that's not what I'm meaning. I mean, look at you! Tell me women weren't slipping you their number. Didn't that feel strange?"

She tilted her head, again looking confused. "Why would it be strange? I've dated women, Kate."

"True. But we were in college. Lots of women tried things in college."

Maura shook her head. "There were trysts after college. Nice women but, I didn't foresee a future so there wasn't a need to introduce them to you."

Kate looked shocked again. "I can't believe you never told me!"

"As I said, they were nice enough but there wasn't a future. Why lead them on by introducing them to my family and friends when there wasn't a need?" Maura sipped her wine again.

Kate shook her head. "But still! We tell each other almost everything. You're generally an open book."

"I still am however Jane has told me there is a use for boundaries in life. It is just that simple."

"How are things with Jane?" Kate asked as she sipped her wine.

"They are fine. How are things with Jeff? The kids?" Maura wasn't sure why but it felt to her that the conversation had taken a strange turn.

"They're good. Jeff is…Jeff," Kate rolled her eyes. "Even less interested in me, if that was possible. He's still a good father but he's pulled away from being a husband."

Maura thought for a moment. "Is it possible he's sensed you having feelings for another woman? Not that if he did that would excuse his pulling away. And not that I generally guess though, it does feel like an educated guess."

"I doubt it unless I talk in my sleep. Besides, he'd try and worm the idea into a three-way if he knew. Honestly, I do not understand men's obsession with that thought. Typically they wear themselves out satisfying one. Why have a second woman there?" Kate had drained her glass of wine and poured herself another.

"From a sociological thought, it could have to do with propagating and spreading his 'seed' to as many women as possible." Maura offered.

"Or they're just pigs," Kate chuckled.

"Well, for someone who likes men and women, I could find it arousing to be with two women at the same time."

"So, you haven't?" Kate asked almost quietly.

Maura shook her head. "The opportunity has not arisen. There would have to be two women I found myself sexually drawn to at the same time and within the same space, also drawn to myself and one another. That can be a very difficult balance."

"Okay, I can see that. But, you do like men. Is the thought as arousing with you and two men? Mind you, they'd also be touching and pleasuring one another."

Again, Maura thought before speaking. "I have nothing against male homosexual behavior or acts but no. It is not as arousing as the notion of myself and two women. However, there are women who do enjoy the idea of two men, engaged as you described. Sexuality is incredibly fluid anymore."

Kate wrinkled her nose. "I didn't really want to think of you with two anyone, Maura."

"You brought the subject up. Now are you willing to tell me more about this mystery woman you have your sights set on?" Maura asked casually.

"I don't know what you want to know, exactly. I already told you, I won't share her name. I-it doesn't really matter, does it?" Kate's voice was nervous.

Maura tilted her head again, thinking. "I am curious. I know the types of women I have been drawn to. Perhaps there is some kind of genetic link." She suggested.

Kate thought for a moment. "She's tall. Athletic build. Olive-toned skin." Her eyes seemed to sparkle as she thought of Jane.

Maura nodded. "She sounds as if she resembles Jane. Jane's very attractive. That's undeniable."

"You think so? I hadn't noticed." She blushed as she lied to her sister.

"Attraction is subjective, but the qualities you listed sounded exactly like Jane. I would add she has an inner strength and prowess that radiates. Confidence, intelligence, compassion beyond belief."

Kate felt herself shake as Maura spoke of her fantasy woman. "H-how did you know?" She looked guiltily up to Maura's gaze.

"I could not be completely sure until you said right now. It was more educated guessing. How you were around her. She's an alluring woman, Caitlin. But you're straight, as far as Jane knows. And married. She doesn't take to anyone cheating, no matter the reason." Maura's tone remained calm and non judgemental. She reached her hand out, touching Kate's wrist gently.

"I-I understand that," Kate nodded. "I just...I can't help it. She's incredible...intoxicating. She's this perfect mix of masculine and feminine."

"I can see that," Maura agreed.

Kate looked to her sister very seriously. "How much do you see, Maura?"

She looked confused. "I'm sorry? Do you mean literally or metaphorically?"

"Both," Kate waffled her head from side to side thinking. "I mean, you're friends. You work closely together. You're best friends, in fact. You told me about that time with Giovanni she pretended to be your girlfriend. Have you never thought of her...sexually?" Kate raised her brow as she asked.

"When we met initially, after the coffee shop that is, I did," Maura nodded.

Kate looked confused. "Coffee shop?" While she wanted to press her sister on her feelings, she was now curious about something she realized she didn't know about the duo.

"Oh. We'd never said? Well, the first time we met, Jane was dressed as a prostitute. A cheap one, at that. She was at the front of the line at a coffee shop Stanley was working in."

Kate looked surprised. "Stanley Stanley? Division One Stanley?"

Maura nodded. "Yes. Anyway, she ordered a black coffee and didn't have the money. She insisted she'd pay him the next day and he waved her off with a rude comment. I felt badly for her and offered her money to get coffee, something to eat and orange juice."

"Orange juice?"

"It has been found night workers notoriously have a gross lack of folic acid due to limited exposure to the sun."

Kate couldn't help but chuckle. "Ever the doctor," she smiled. "Go on?"

Maura nodded and went on. "Of course she refused in her usual Jane way with people she doesn't know. I was of course rather stunned but she went on. Later that day we ran into one another in the department. I thought for a moment she'd been brought in on charges but she was talking with Lieutenant Marks. He was head of the Vice Unit at the time. Instead of guessing further on if she was just an informant or something,I asked around and it turned out she was a Vice Detective."

Kate thought over what Maura said. More like she was glued to the mental image of Jane in some Pretty Woman type hooker outfit. "When did you meet her following that?"

"I'd just been made Chief Medical Examiner of the Commonwealth the first time. Jane was wanting to get into Homicide. Sergeant Korsak was her mentor and he told her to come down to the morgue with him. 'Part of a building a good case is knowing exactly how the victim died.' Well, at the time, he was working on the Riverside Rapist case. As you recall, the suspect originally broke into single women's homes during the day, waited for them to return, raped and then got away. The particular victim they came down to see was Arissa Liongate. She had an enlarged heart and the combination of adrenaline, fear, various chemicals and stress to her heart caused her to have a heart attack."

Kate nodded. "I-I recall that case. You were very tight-lipped about it. But you're that way with all your cases."

Maura nodded. "It's being professional."

"Was Jane surprised to run into you?" Kate asked.

"She was. I simply smiled and extended my hand, introducing myself. She stammered a little. It was very endearing," Maura smiled wistfully.

"And then you had feelings towards her?"

"Well, it's hard not to. It was a whirlwind at that time though. Jane was just helping Korsak and his partner on her days off. She figured out the suspect was an internet installer which broke the case. She quickly went from Vice to taking the Homicide test and passing. So she went from another detective to one I was working closely with. I became too happy with the fact she was my best friend to think sexually. However yes, it has crossed my mind."

"But you've never...?" Kate asked.

"Never?" Maura thought she knew what she was being asked but wasn't one to assume.

Kate chuckled. "Never acted on anything?"

"Of course not. She's a colleague and a good friend."

Kate studied Maura. "But you're upset. She...went home with someone? There's a tension about you."

Maura knew she couldn't lie. "Yes, she did. And yes, I was…," she paused. "I am jealous." The sandy blonde swallowed her last sip of wine.

"You know, if you went after Jane, she wouldn't resist," Kate pointed out. Her mind felt fuzzy as the effects of the wine were setting in. She cleared her throat. "I-I've been rather worried you would cross that line and go for her, to be honest."

Maura reached for her sister's glass and set it aside. She knew Kate only got this honest when she was tipsy. "I wouldn't dream of ruining our friendship and working relationship like that, Caitlin. I've been through relationships like they were tissue paper at times," Maura shook her head.

"Deep down you know it wouldn't be like that with Jane. I see the way you two look at each other. If people could have sex just by looking at one another, you two have done the Kama Sutra and made an addendum. There's more than just that between you though. Really, I'm just stating the obvious." She tapped her fingers on the table before yawning. "I should probably go."

"You're in no condition to drive. And while I seem better off, it's probably not wise for me to drive either. Come, you can sleep in a guest room and drive home tomorrow? I'll call Jefferson and let him know you're here." Maura got up, waiting to see how steady Kate would be.

She rose slowly, bracing herself on the island before standing fully. "See? There. I'm fine," Kate nodded before almost tripping over her own feet.

Maura moved quickly and caught her sister. "I don't believe this falls under any definition of 'fine,'" she countered. "Let me just help you to the room." In truth she wasn't really asking her sister as she came behind the woman, assisting without any real clearance to do so.

Kate wasn't in a state to protest. When it came to drinking, the fact she hadn't eaten and the three glasses she'd downed were more than enough to put her under.

Instead of risking the stairs in her state, Maura took Kate to the guest room on the first floor. She got her sister inside and set her on the bed. "Do you want help getting your things off?" She asked gently as she turned to make sure the blinds and drapes were drawn.

The only answer she got was silence. When Maura turned back around she found her sister slumped over messily, her head right below where the pillow was. She went over and helped Kate out of her clothes, leaving her in her under garments and got her into the bed properly. She folded the clothes and set them on a settee and went back to the kitchen.

She came back with a bottle of water and two Advil with a note, Take these when you wake up and drink the full bottle. The note was just in case Kate woke before Maura or after Maura had to leave for work.

As she promised, Maura took out her phone and called Jefferson's phone.

"Hello?" The man asked sounding puzzled at why Maura would be calling so late.

"Jefferson, I'm calling to let you know Kate drove over here and had a little too much to drink so she's sleeping it off in a guest room. She'll be back in the morning."

The man paused for a moment. "Kate isn't here? I thought she was upstairs."

"No. She said you were working and the kids were asleep so she went for a drive." Suddenly she was puzzled how the man wouldn't have heard his wife leaving.

"Ah, well. Thanks for letting me know. This damned Fyvet Merger has me so distracted I probably wouldn't have made it up to bed anyway. I'll get the kids off in the morning. Have a good night." The man added out of politeness.

"Thank you. And you." Maura hung up her phone as she headed finally to her bedroom. 'He's so distracted with work anymore I'm not sure he knows anyone else exists at times. We haven't been intimate in almost a year. I swear I'd think he was cheating but he doesn't have the time. I mean, I did worry about that and I...I went through his things. I know, I know,' Kate waved her hand. 'How could I not worry after months of him not touching me? Not really being there as my husband anymore? But, looking through everything, I found nothing but all the statements of billable hours he's turned in to his firm. The money is nice but I'd like to have the man I married back.' The confession from Kate on the state of her marriage was a few months back. From what she could deduce, it didn't sound as if things had improved. And, if her sister was now setting her sights on her best friend, it didn't seem likely things would improve.

"It's none of your concern right now," Maura told herself as she got into her bedroom. Looking at her watch she turned the shower on instead of getting a bath. As much as she tried not thinking on it, all Maura could do was let her mind wander to what Jane and her lover were no doubt up to. As the water washed over her, she finally let herself cry. Maura was never one to scream or act out her anger. She was one to let it all burst out in tears.

She was jilted out of her thoughts as the water turned cold. The sudden pelleting of cold against her hot skin was more stinging than it would be had her body been at it's normal temperature and not warmer due to the hot water preceding. She quickly reached for the knob and turned it off.

The chill caused goosebumps on her skin and her nipples to harden before Maura could grab a towel. She dried in the stall and then stepped out onto the bathmat. As she didn't wear anything to bed and hadn't gotten her hair wet, she pulled the covers back on her bed and slipped between the sheets.

While Maura had a fitful night of sleep. Jane's was far more energetic. She laid back on the bed, black hair matted to her sweaty back. Jane drew a ragged breath, looking at the red-head smiling next to her. "You look like the cat that ate the canary," her voice husked deeply with lust.

"Well, I ate something but it wasn't a bird," the Southern drawl dripped off her lips.

She chuckled as she reached over to the nightstand and found her Gatorade. After Jane took a swig, she offered it to Sarah.

"Hmm, thank you," she smiled, taking the bottle and a sip herself. "I do need to replenish my electrolytes," she winked as she passed the bottle back.

After a few moments in comfortable silence, Jane had regained herself. "Now it's my turn to feast," she smiled wickedly, turning the tides and topping her lover.

Sarah drew her finger over Jane's lips. "My my, what full lips you have," she grinned.

Jane played along. "The better to," instead of saying, she dipped her head down, kissing Sarah deeply.

Sarah moaned, taking Jane's hands in her own. "My my, what long fingers you have."

"The better," Jane smirked as she drew her fingers down Sarah's quivering body. "To," she found her lovers wet, waiting center, working three fingers skillfully inside.

As Jane thrust and moved inside her, all Sarah could do was pant and moan. "Ooooooh goddddd," she felt herself beginning to ride against Jane's hand.

"You know I love it when you're nice and wet for me." She kept pumping her fingers deeply until she couldn't take it anymore and went between Sarah's legs, licking and lapping at wet folds.

Sarah gripped the bedding tightly before running her fingers through Jane's hair. As the woman kept going, she knew Sarah was close because she began tightening her grip on Jane's hair and inner walls were squeezing the thrusting fingers.

Not one to let up, Jane latched on to the stiff clit, sucking and nibbling it. It felt like slow motion but her lover went stiff and then shook. The gravity of her orgasm so strong she couldn't make a sound for several seconds.

"Ooooh godddddd," was all she could finally muster when she found her voice.

However, Jane wasn't done. She gave Sarah a few moments to recover before resuming her assault of pleasure.

"You're going to kill meeee," Sarah teased.

Jane's dark brown eyes looked up to Sarah's, a glint of a smile very evident as she kept going.

Finally the two laid in the mess of sheets and each other, unable to keep going. She knew she'd face hell in the morning with so little sleep, but Jane didn't care. For once she was too busy feeling joy she didn't miss the idea of sleep.

When Maura woke the next morning, she first thought to get two cups of coffee and go to Jane's. But, when she remembered Jane was entertaining, that was the farthest idea on her mind. No, she'd get an extra cup and meet her friend at the station.

Oddly, the two were heading to the elevator at exactly the same time.

"Jane? For you," Maura offered the cup.

"Thanks, Maur. I'm dead tired." Jane thought she saw her friend flinch out of the corner of her eye but she wasn't willing to pursue it in her state.

Maura didn't want to pursue a conversation on why her friend was tired. She had more than enough of an idea why Jane was tired. "I should have the results back on the glasses we tested. I'll get that report up to you soon."

"Sure," Jane nodded. "Sounds good." Jane wasn't in a state to have an in depth conversation with Maura at the moment but she could sense her friend was upset. If she didn't know better, she'd think her friend was jealous.

The elevator stopped at the Homicide floor first. "See ya later, Maura. Thanks again for the coffee."

Maura nodded and gave a polite smile. "Of course, Jane." The door shut and the elevator resumed it's path down to the Morgue.

When Maura got to her office, Suzie met her, manila folder in hand. "Good morning, Dr. Isles. Here's the findings on those glasses."

"Thank you, Suzie," Maura smiled, taking the file before going to sit at her desk. Normally Maura was more formal with her staff. However, as the two women were alone and fairly close, it was more comfortable to be personal versus professional.

The chief criminalist smiled and nodded. "Did you have a good evening?" She made polite small talk.

"It was different for me," Maura nodded as she thought. "Not just going undercover. When I had gotten home, Caitlin surprised me out of the blue. Typically she calls first but she didn't this time. We sat and talked over wine. As the night wore on we both became too inebriated to drive so she slept in one of my guest rooms."

Suzie listened and nodded. "It must be nice having a sibling. Then again, you also know what it's like being an only child."

"It can be nice," Maura nodded. "It can also be cumbersome. I should get on making the report for Detective Rizzoli. We'll talk more later?" She gave a polite smile.

"Oh, of course. My apologies," Suzie nodded, pushing her glasses up the bridge of her nose before she turned to go.

It didn't take the Medical Examiner long to complete the report. She printed off the file and went to the elevator. She found herself tapping the folder in her palm nervously.

When she got off the elevator, she was greeted by Detective Cooper. "Hey, Dr. Isles. How are you doing? How was the rest of your night?" She asked, a grin on her lips.

"My evening was more eventful than I'd planned," she nodded, smiling. "How was yours, Riley?"

The woman thought for a moment. "As eventful as Jane's?" She asked with a quirk in her brow. "Mine was fine. No big dates or anything. That dress was incredibly flattering on you, by the by."

Maura blushed at the question and then the compliment. "No, not as Jane's might have been. My sister dropped by unexpectedly."

Before the conversation could go on, Jane wandered over. "Is that the report, Maura?" She motioned to the folder Maura was holding.

"Oh, yes," Maura smiled, handing Jane the file. "All your dates were ruled out as suspects."

Jane nodded, looking at the report. "Well, good to know I didn't date a killer."

"Or sleep with one?" Riley teased. Jane shot the woman a look but didn't respond.

"I'm going to get another cup of coffee in the Division One. Can I bring anyone back anything?" Maura asked, looking to the women.

"Coffee sounds good," Riley smiled. "I'll tag along, if that's alright? Want me to bring you anything, Jane?"

The raven-haired detective shook her head. "I'm going to go over this with Korsak. Hurry back, we've got to keep looking for the links here."

Riley nodded. "Will do. Shall we?" She smiled, looking to Maura before making a sweeping motion with her arms.

"We shall," Maura nodded and headed for the cafe.

Before they got there, Maura was surprised. "Kate?"

The woman stopped and smiled. "Hi, Maura. I'm sorry for just dropping by again. I just wanted to thank you in person for last night."

Maura nodded and smiled. "Oh, Kate, this is Detective Riley Cooper. I know you two haven't formally been introduced."

Riley stuck out her hand, shaking Kate's. "Well, we've said hello, but it is very nice to meet you, Kate."

The touch of hands sent a jolt through Kate she couldn't fully explain. "I-it's nice to meet you as well, Detective Cooper."

"Just Riley, please?" She held Kate's hand longer than need be before letting go with a smile.

"Certainly," Kate smiled and nodded. "I should get going. I'm sure you both are busy."

Maura nodded. "I'll call you later, Kate. And last night was no trouble. You're my sister. Kiss the kids for me?"

"Will do," Kate nodded.

Before she could go, Riley reached into her pocket and found her card holder. "And, if you'd ever like to chat, feel free to call me?" She asked, a smile on her lips.

Kate smiled, slipping the business card into her pocket. "Thank you, Riley. Will do." Kate gave a final smile and headed out.

Maura thought for a moment the detective was flirting with her sister but shook her head, thinking against it. They both ordered their coffees.

"Well, I'll see you later, Dr. Isles. Better get back before Jane bites my head off," Riley winked.

"Alright, Riley. Yes, I'll see you later. Have a good shift." Maura hung back for a few moments, sipping her coffee.

She stood there long enough to spot a red-head walking into the station. Her mind immediately flashed back to Jane's date last night. Maura thought she'd avoid the woman until she came waltzing into the Division One.

Sarah could feel eyes on her as she walked in. She quickly glanced around and her eyes fell on a woman who looked rather familiar. "You must be Dr. Maura Isles?" The woman asked with an intoxicating southern accent.

Maura nodded. "I am. And you are?"

Sarah politely extended her hand. "Sarah. Just Sarah. I'm a photographer friend of Jane's. She's told me quite a lot about you," she said with a light smirk. "She wasn't entirely accurate on your beauty, though."

In an instant, having her suspicions confirmed, Maura felt a flash of anger that quickly cycled to confusion. "I'm sorry?"

"You're a very attractive woman. Whether you're wearing that get up from last night, or this stunning number. I bet you'd make a potato sack look sexy."

"Thank you." She responded more out of formality than a desire to. "I really should get-"

Sarah reached, taking Maura's hand in her own. "People are always rushing. If you ever take a moment to not rush," she smiled. "There's my card with my hotel and room number. I'll be there through the end of the week."

"I-I don't think Jane would appreciate her lover hitting on her friend." Maura shook her head.

"We're not exclusive, but you're right. Just, not for the reason you'd think," she said with another coy smile.

Again Maura was confused by the cryptic nature of the comment. "Alright. I should get back to the Morgue. I'm on a case."

Sarah nodded. "If you lose the card, Jane has my info. I hope to see you around." She watched the medical examiner walk away, licking her bottom lip.
