Jane carefully folded her folder after signing off on the file. She sighed as she added it to the mountain of paperwork on her desk. Looking at her watch she noted the time and moved to pick up her jacket and head down to autopsy to pick up Maura. They were supposed to go running after work. Jane made her way down to see her friend when laughter coming from the medical examiner's office made her pause. She heard Maura giggle and squeal which made Jane even more curious. Dr. Isles did not giggle like a little school girl…..

The sound of male, husky laughter joined hers and Jane slowly drew her gun and tip toed down the hallway. 'Just in case.' She thought to herself. She peered around the half-opened door to see her best friend sitting atop her desk, her arms around the neck of a dark haired man. A dark haired man who looked oddly familiar.

'Frankie!' Jane almost gasped aloud as it dawned on her that her baby brother was currently leaving kisses all down Dr. Isles' neck, his hands circling her tiny waist. Never in a million years did she think her wealthy, sophisticated friend would fall for her blue collared, baby brother. She slowly put her gun away, keeping out of sight of the two lovers. It had been while since she saw Maura genuinely happy these days. But watching her in Frankie's arms, she could see the light back in her eyes, her smiled not forced but took over her face like a sunflower in summer, bright and alive. Jane observed the way Frankie's eyes never left hers, a goofy love-sick grin on his faced as he allowed Maura to mess up his hair, causing her to laugh at him.

Jane silently made her way back to her own desk, not wanting to interrupt. She frowned as she thought of her best friend with her brother. Is this ok with her? She knew no matter what she thought, it was their decision. But why didn't they tell her? Or anyone, for that matter? Jane decided to just send Maura a text asking if she still wanted to run tonight, so that gives her the option of staying with Frankie if she wanted. Locking up her desk drawer, she made her way home.

"Frankie…" Maura giggled as he softly tickled her sides. She grabbed his head in her hands and kissed him, fiercely, making his knees weak. Her hair framed her face, the scent of her perfume invading his senses. Frankie broke the kiss to take a deep breath. He looked down at the gorgeous woman in his arms and sighed happily. Maura was slowly becoming the breath of fresh air he'd been looking for. The kind of woman who, even on the toughest days, made everything seem right. She made him want to be a better man, motivated him to be the best he could be. The way she looked at him, her hazel eyes shining in adoration, filled him with a sense of pride. This breath-taking woman, so smart and classy, the woman every other man in the Police building desired and lusted after, chose him. She wanted him and that simple fact sent him over the moon.

He was about to tell her what was on his mind when her phone beeped. Maura frowned and turned in Frankie's arms to reach her phone. "I hope it's nothing important." She muttered as she checked her messages. Frankie was hoping for the same thing, the two of them had big plans. "Is everything ok?" he asked her, noting the look of dilemma on her face.

"Jane wants to run tonight. I completely forgot I asked her to do that with me tonight." She said apologetically. But Frankie understood. He knew Maura was in a vulnerable state right now and she needed her best friend. He released his grip around her waist and took her hand, helping her onto her feet.

"It's ok, babe." He told her. "I understand and I can come over later if you still wanted." He said uncertainty, not knowing whether or not she still wanted him over. Maura nodded vigorously.

"Of course!" she exclaimed. She wrapped her arms around his waist and kissed him before pulling back to gaze up at him. "I really do like you a lot Frankie and I definitely want us to figure all this out. I'm afraid of messing this up with you." She confessed.

Frankie's eyes softened and placed a gentle kiss on her freckled nose. "You could never mess this up. I've waited so long to be able to call you mine and I sure as hell am not gonna let anything happen to us. I think we should talk tonight when you get back from your run and we'll discuss it further." He said as he reluctantly let go of her. Maura smiled at him before turning to pick up her bags.

"Walk me out?" she asked him, shooting him a smile. Frankie grinned back and took her heavy bags from her, and followed the doctor out to her car, trailing her like a little puppy in love.

"All I'm saying is that the Red Sox should've won that game!" Detective Korsack argued as he and Frost made their way to their cars. The two were constantly bickering like an old married couple and tonight was no exception. Frost shook his head at the older man.

"No way! The Sox are the worst!" he argued.

"How can you say that? You live in Boston!" Korsack exclaimed, genuinely confused by Frost, who just laughed aloud.

"Just because I live here doesn't mean I have to support their team!" he explained, still laughing at the older detective's look of outrage. "Why? Is that why you support them?" he teased.

"No!" Korsack was about to explain further when he stopped short. Looking out towards the parking lot to see what had drawn the man's attention, Frost froze at the sight of Dr. Isles leaning against her car and Frankie Rizzoli kissing her passionately.

"What-" Frost started but held his tongue as the pair watched the young couple. Frankie took Maura's hands in his and rested them on his chest, slowly letting his hands travel down her arms, tangling them in her long, luscious locks as they kissed goodbye. Korsack held his breath as he watched the young woman he thought of as a daughter fall in love with the young detective-to-be.

"Did you know this was a thing?" Frost whispered. Korsack shook his head slowly. They watched Maura and Frankie stepped apart and he helped her into her car, giving her one last good bye kiss. They shared words that the two detectives couldn't hear, but they assumed whatever was said made Maura happy as she laughed, her face breaking out into a happy grin. It was good to see the doctor smile again. Frankie took special care to make sure she was completely in the car before watching her drive away. He put his hands in his pockets and walked away, whistling away, his eyes bright and happy, the look of a man head over heels in love.

Korsack turned and looked back to Frost. "Ummmm…" he was unsure of what should be said to the sight they witnessed. Dr. Isles who was the most sophisticated, upper class woman they had met, had gone and fallen in love with a blue collar, below average salaried police officer…? It didn't make sense to either of them. Then again, you don't chose who you fall in love with.

"Should we tell Jane?" Frost asked after a minute. Korsack thought for a moment before responding.

"No. Did you see the look of happiness on their faces? When was the last time we saw Dr. Isles that happy? She needs this right now. Jane will find out soon enough." Korsack stated, trying to protect and preserve Maura's happiness.

Frost nodded in understanding before adding, "So… you think they've done the nasty? You think Frankie's gotten to see her naked yet?" Korsack turned and smacked the back of his head. "Perv." He shook his head before walking away. Frost chuckled and followed after him. It was no secret that Dr. Isles was the most beautiful woman working in the Boston Police Department and has been the topic of discussion in the men's locker room, more than once.

Jane was nervous as she and Maura jogged through the streets of Boston. 'Should I say something?' she wondered. But looking over at her friend, she knew she couldn't spoil her happiness. Even though Jane wanted to gag at the thought of her friend being attracted to her brother, she vowed she wouldn't be the one to ruin their happiness. She tried to think of all the good things that could out of this. 'Maybe he'll teach her how to pay baseball and basketball properly.' She mused to herself as they reached the top of the hill.

Maura looked over at Jane to see her deep in thought. She was about to ask her what was on her mind but decided against it. The silence was nice and it gave her time to think about Frankie and be honest with herself about what she truly wanted out of their relationship. She could feel herself slowly becoming addicted to the taste of his kiss, his intense gaze that left her weak at the knees, his funny goofy sense of humor that never failed to make her laugh. She never felt so alive. She had always kept a rational mind when it came to men. But Frankie made everything irrational and it scared her but she knew he would never hurt her. She trusted him and knew if she was scared he would be there for her every step of the way. Her feelings for this man were taking over her mind, body and everything in between. She only hoped he felt it too.

Jane and Maura slowed their pace as they turned onto Jane's street corner. They slowed it down to a walk and made light conversation till they neared her apartment when they noticed a man standing outside her door.

"Who is that?" Jane wondered aloud as she tried to get a good angle of him. Maura panicked and ducked behind the bush.

"I forgot my pepper spray!" she explained. Jane rolled her eyes.

"I think… is that… it's Casey!" she exclaimed. "I haven't seen him in months!" Maura saw the look of excitement on her friend's face as they jogged over to him.

"Casey!" Jane called. They stopped as they both noticed Casey had surgery on his leg. "Wow!" Maura said excitedly. "I thought you couldn't walk anymore1 I can't believe this!" she said as she inspected his leg.

"I almost can't believe it." He laughed, his eyes focused on Jane who was in stunned silence. This changed everything. Maura could sense the sexual tension and wanting to get home to call Frankie, decided to make a quick getaway. But first she was gonna help her friend out.

"So, how's everything sexually speaking?" she said bluntly. Jane's eyes widened and looked like she wanted to either strangle Maura or sink into the floor. "Dr. Isles! He is not one of your patients!" Jane reprimanded, trying her best to sound like her mother.

Maura smiled apologetically although inside she was giving herself a high five. She quickly excused herself but not before saying her good byes and reassuring Jane she didn't need to walk her home. She needed to get ready for Frankie.

She left the couple standing awkwardly in front of Jane's apartment and jogged back to her place. She stopped short when she saw Frankie leaning against his car waiting for her. She grinned at the sight and ran into his arms.

"I kinda missed you." He teased as he captured her lips in his. Maura huffed and bit his lip playfully. "Just kinda?" she questioned. Frankie grinned and picked her up, wrapping her legs around his waist as he brought her up the apartment stairs. He set her down so she could get her keys out. "Ok, I missed you like crazy." He confessed as she pulled him inside. Angela was out for the night so Maura wasn't worried about anyone walking in on them. She had a feeling Jane was going to be busy for the rest of the night.

Maura went to the kitchen to get a glass of water and offered one for Frankie. She felt the sparks fly when their hands touched. "Thank you." He whispered.

"Frankie, I want this." She began before his smile got to her and ended up kissing him instead of having their talk. "I want us to work out but we need to figure out what we're doing. And what about Jane and the team? And your mother? What will she think?" Maura asked him, her eyes widening at the thought of losing the Rizzoli's as friends. But Frankie's gentle smile calmed her as he tugged her into his arms.

"I want this too, Maura. You're the only woman I want in my life and I've wanted to be with you for so long. We can keep it from the team till you're ready but I want to tell them eventually. I'm so happy with you and where we're going and I don't know how long I'm going to be able to keep it in." he admitted as he stroked her back. Maura pulled him down for a kiss and whispered, "I know, I want to tell them soon but for now can we just share this, just the two of us?" she pleaded. Frankie nodded and hugged her little body tightly. "What we have is ours. They can question it and judge or accept it and be happy for us. Either way, I want you badly and I'm not ready to give you up so easily." He held her before kissing her once again.

Maura moaned and wrapped her arms around his neck. Their tongues battled and danced as the two lovers shared their moment. Frankie sighed happily in her mouth; this is where he belonged. With this beautiful woman with whom he was falling rapidly in love with. Maura surprised him by sneaking her hands in his shirt. The feel of her hands crawling up his back had him turned on in an instant. He quickly pulled back to unzip her jacket and find some skin to explore. Her taut stomach seemed like a good place to start. She whimpered as his body pressed hers into the counter. He picked her up easily and set her down on the kitchen counter. Maura licked her lips in anticipation. Helping Frankie get rid of his shirt, she moved to remove her own. Frankie's eyes traveled over her body, his fingers aching to touch that soft skin.

Maura sensed his hesitation and reached for him, placing one hand on her hip, the other interlacing with her own. She played with the faint hair on his chest and moved her legs up further to bring him closer. Giggling, she left open mouthed kisses on his chest. Frankie groaned as her tongue flicked over his nipple and shuddered as she blew cold air over it.

"Damn." He whispered before removing her sports bra. Maura immediately felt the cold air hit her but was warmed by the look of awe she was receiving from Frankie. His eyes worshiped her body before gathering her in his arms, their topless bodies pressed tightly against each other.

"You're breath taking." He told her as he held her against him. Maura smiled gently and turned her head to kiss his neck. "So are you." She sighed as her eyes swept over his body. The muscles rippling and moving as he moved, was hypnotizing to her. She traced over the broad shoulders and hung on as he swooped down to leave a trail of kisses down to her breasts. Maura cried out as he took her nipple in her mouth, sucking firmly. She arched her hips and squeezed his hips with her legs, the sensations of his mouth doing spectacular things to her. Frankie moaned and turned to switch breasts.

Angela Rizzoli and Lieutenant Cavanaugh laughed amongst themselves as they headed up the steps to Maura's home. "She said she was going on a run with Jane so she probably won't be home." Angela explained as she and the Lieutenant walked through the door. Closing the door behind them, the pair made their way to the kitchen only to be greeted by quite a sight.

A topless Frankie leaning over Maura's naked torso, her head tilted back, his mouth fused to her breast, one hand massaging the one not in his mouth. Maura's hands leaving scratch marks down his back as he pleasured her, both had their eyes closed and lost in each other that they didn't notice his mother and the Lieutenant standing there, mouths open in shock.

Lieutenant Cavanaugh was the first to jump into action and grabbed Angela by the elbow and dragged her out of the house. "I don't think she's running with Rizzoli anymore…" he whispered as he ushered a stunned Angela out the door. Angela couldn't even speak words; she was so taken back by what she had just seen.

"My son… Maura… naked… sex? Are they…? Since when?! Does this mean? ….. Did you know about this?" she turned to Lieutenant Cavanaugh who backed away from the woman.

"No! I had no idea, this is certainly news to me." He reasoned with her. And it was the truth, he had no idea his soon-to-be detective was banging the medical examiner.

Angela accepted his answer and cleared her throat. "Well we certainly can't go back in there." She said. Cavanaugh shook his head and replied, "Well there's always my place." Angela nodded and took his arm, the two of them getting back into the car and leaving. Her mind was spinning by what she saw between her son and her friend. But she had time tomorrow to worry about them. For now, she had a hungry Lieutenant she promised dinner to.

Later that night, Maura and Frankie laid in her bed, their naked sweaty bodies pressed together, the sheets wrapped around them. Maura was drawing little circles on his chest as he caressed her soft, silky back. Both of them completely oblivious to the fact that Frankie's mother had seen them half naked only several hours earlier.

Maura listened to the strong beat of Frankie's heart as she closed her eyes. She was exhausted and wanting to sleep. Frankie turned over and pulled her body into his chest and felt her relax against him.

"Good night, my love." He whispered. He felt her smile against his chest as she replied with a good night to him. Her last thought before drifting off to sleep was how they were going to tell the others.

Little did they know all their friends already knew…
