This is a new story - super silly and fun (hopefully). I'll have the second chapter up asap. Let me know what you think! :)

"We'll just stop by." Dr. Maura Isles added her signature to some paperwork and then glanced up at Detective Jane Rizzoli. Jane was hovering over Maura's desk, her hands on her hips, her mouth scrunched up in her I'm-Jane-Rizzoli-and-I'm-not-pleased expression.

"It's her birthday, Jane," Maura said, capping her pen and sighing. "She's a very hard worker and I want to make sure she knows I support her. What if Pike tried to steal her away?" Maura stood and smoothed the wrinkles from her crimson dress. "No way. Susie is mine." She finally gained eye contact with Jane and saw just what she was afraid she might – Jane looking grouchy.

"Ten minutes," Maura said. "We'll stay for ten minutes. At the most. Don't make me go alone, Jane. You know my cortisol levels spike when I have to go to social engagements. If you go with me, you'll be saving my life in a way. My stress levels will be lower, my heart will be healthier, my…"

"Fine, fine!" Jane said, holding up a hand. "Ten minutes. Then we get a beer and a burger at the Dirty Robber and you have to watch the entire Red Sox game with me."

"The whole game?" It was Maura's turn to make a face. "Well, can we at least watch it at my house? The couch is so much more comfortable than those chairs at the Dirty Robber, not to mention the levels of bacteria in my snacks are…"

Jane held up a hand again. "We'll get the burgers to go."

"I'll have a kale salad."

"OH MY GOD, MAURA, YOU'RE KILLING ME." Jane laughed and walked around the desk. She grabbed Maura's hands and dragged her toward the door. "Get your bag and let's get out of here. The faster our little adventure at Susie's party is over, the better."

Maura grabbed some folders from her desk, and her purse, and headed for the door. Jane was right behind her muttering, "The things I do for you…"

Maura swung around and pointed a finger at Jane. She was smiling, but her voice was sharper than usual. "I'm just asking for ten minutes, Jane. And you've roped me into innumerable hours of tedious baseball as payment. So, really, it should be me sighing, 'the things I do for you.'" She jabbed Jane in the shoulder with her finger, then flipped her hair as she turned and walked through the door.

"Jeez, Louise," Jane answered, rubbing at the spot Maura poked. She turned the light off in the MEs office as she followed Maura to the elevators.

Maura couldn't remember a Friday night she hadn't spent with Jane in the past few years. They were inseparable, really, often spending most weekends with one another. Maura marveled over how she didn't really miss all the time alone she used to have. She'd spent so much of her life alone, it was almost strange how comfortable she was sharing so much time with Jane. They were like sisters, really. Best friend, sisters.

But no. That wasn't true. While Maura definitely had a fondness for Jane and all of her quirks, sometimes she'd discover an irregularity in the fondness. A kind of spark or shiver that seemed out of place if she was thinking about a sisterly best friend. Maura had pushed those sparks and shivers to the side, though, and did her best to ignore them. Obviously, Jane was interested in Casey, even though he was constantly hurting her, leaving her, leading her on. And Maura didn't want to risk losing what she had with Jane by even thinking about what a spark or a shiver could mean. No way. Well, unless it was late at night and she'd had a couple of glasses of wine, and Jane was a safe distance away at her own apartment. Then Maura could let herself have just a tiny what if moment that might include thinking about the Detective's deep brown eyes. Or the shape of her lips. Or the shape of her body. This would lead Maura to a guilt-ridden night of bad sleep, so it wasn't a train of thought she allowed to barrel through her very often.

It had been happening more often, though, lately. What was getting into her?

"Maur-? Hello?" Jane waved her hand in front of Maura's face. Her other hand was holding the elevator doors open.

Maura startled out of her thoughts and then smiled brightly. "Thanks for holding the door, Jane," she said, trying to cover up what she'd been thinking. She walked past the detective and toward her car in the garage. Jane followed without even asking. Of course they'd take the same car to the party. Though Jane would've liked to be the one driving.

"What do you think would be a nice hostess gift?" Maura asked, unlocking the doors.

Jane tucked her long legs into the car. "The promise that we won't stay long?" She gave Maura a sarcastic smile.

"I was thinking wine, Jane. Maybe a nice Cabernet?" Maura adjusted her seatbelt and hit the start button. She'd left the Prius at home. Today felt like a Mercedes roadster day.

The first sign that the party might be something different than either Jane or Maura expected, was the line of cars parked all along Susie's street.

"Are you sure this is the address?" Jane asked, peering out the window. She could feel the rumble of the music even inside Maura's billion dollar, highly insulated sports car.

"I know it is." Maura answered, her forehead furrowed in concern. "I've been here before to drop off softball supplies."

Jane's eyebrows rose. She turned and stared at Maura, a smirk playing at her lips.

"Oh, don't look at me like that, Jane." Maura dismissed. "I had shirts printed for our team and needed to drop off Susie's. I just left it on the porch." She glanced sideways at Jane, unsure how to read the look on her friend's face. Amusement? Relief? Why would Jane feel relief that Maura had only ever been on Susie's porch?

Maura cradled the wine in the crook of her elbow as she reached for the doorbell. She was uncharacteristically out of breath after having had to walk at least a mile in her Jimmy Choos. Her feet were killing her now, but she would never admit to it.

"This is not a doorbell kind of party, Maura," Jane laughed. The music was making the door vibrate. They could hear laughs and shouts – and was that a lamp breaking? – from inside. "Come on, Doctor. Let's go see what the hell Senior Criminalist Chang is up to." Jane reached for the doorknob. Maura reached for Jane's hand.

"Jane! You can't just walk into someone's house…" But Maura's hand was too late. Jane had opened the door. The two were met with a gust of sweaty air, and the thumping beats of a song with lyrics that made Jane blush. And nothing makes Jane blush.

"Ten minutes!" Maura shouted over the music to Jane. Her face was a mixture of confusion, worry… and excitement. Maura had never been to a rager before. She peeled off her coat and handed it to Jane, who was standing next to a coat rack. The rack was bulging with coats – but also with sweaters, and a couple of pairs of jeans, and a bra.

Jane and Maura saw the bra at the same time. Jane found herself completely speechless, while Maura burst out laughing.

Jane's voice reappeared, and cracked as she sputtered, "Wait. Wait. Wait. Is this a NUDIST party, Maura? Did you neglect to tell me this was a party full of NAKED STRANGERS?" Just then the song stopped, and Jane's last statement echoed through the house.

A completely nude man streaked by. He was holding a giant copy of Gray's Anatomy and shrieking something about, "hiding this in a place you'll never find it."

"Oh, I love that book," Maura murmured as the man ran by. Jane took a step closer to Maura and grabbed her arm. Was it in a protective way or in a "protect me" way? Maura couldn't tell. She saw Susie bouncing toward them, though.

"You made it!" Susie said, clapping once with excitement. "Come on, the drinks are over here." She turned and jogged down the hall.

"You did not tell me that Senior Criminalist Susie Chang's breasts were also invited to this party," Jane whispered between clenched teeth. Her breath was hot in Maura's ear. Maura turned quickly to answer – almost too quickly – her nose brushed Jane's. They both pulled away, momentarily flustered.

"Of course her breasts would be invited, Jane," Maura whispered back. "They are attached to her body. As we could both just see."

Jane rolled her eyes to the point of nearly spraining her forehead, and she continued to clutch Maura's arm as they walked toward wherever the drinks were hidden.

"One drink," Jane said, again through closed teeth. "And then we are so out of here."

Maura laughed. She found this whole situation puzzling and fascinating. A nudist party! She'd never been to one before. It was so interesting how everyone seemed to just be hanging out and talking, wearing barely any clothes. It was much like she imagined a conference room whenever she had to give a presentation. There are no pretentions when everyone is nude.

Jane stopped suddenly, nearly pulling Maura off her feet. "Wangs," Jane sputtered. "So many wangs." And Jane was not wrong. There were at least five men standing around a keg, and none was wearing a stitch of clothing. Susie gestured at the red Solo cups and then bounced off to turn the music back on.

"I'm not going over there," Jane said, scrunching up her nose. "Look at them."

Maura scrunched up her nose, too. "Well, I agree that male genitalia is not my favorite thing to look at – especially in its flaccid state. But that's Blue Moon beer in the keg, Jane. See? Your favorite."

"I wasn't talking about their genitalia, Maura," Jane said, shoving Maura in the shoulder. "I just meant look at them talking. They're measuring dicks, while their dicks are out."

Maura laughed, and turned her sparkling eyes to gaze at Jane. "I'm sure if you had a penis, Jane, yours would be bigger than all of their combined."

"Gross, Maura," Jane said, with a laugh. "But… thanks?" She took a deep breath, like she was about to jump into the deep end of a pool. "OK. I'm going in. You want a beer, too?"

"Why not," Maura replied. She was starting to feel warm in her dress. And her feet were killing her. She kicked off her Jimmy Choos and hid them in a corner behind a couch. Jane found her a few minutes later.

"Here you go, my friend," she said, handing Maura a red cup. "I was very careful to keep it from being contaminated with any wangs."

"That was very thoughtful of you, Jane," Maura laughed. She settled into the couch and patted the seat next to her. Jane was trying to ignore the groups of naked, or partially naked people that filled the room. They were all chatting or dancing, and acting like this was all perfectly normal. Which, to them, it probably was.

Jane sat down next to Maura and the couch swallowed her up, pitching her towards her friend. Their arms touched, causing Jane's beer to slosh onto her pant leg. "Shit," Jane said, rubbing at the spot.

"It's OK. I don't think it will stain." Maura reached over to sweep away some of the excess liquid, her hand rubbing back and forth on Jane's thigh. A woman's laugh came loudly from the corner of the room. Jane and Maura both glanced up to see the woman – bare-chested, leaping onto Susie's bare back. Soon another bare-breasted woman was on the back of a naked man, and the two groups were racing down the hallway, careening around corners and laughing crazily.

After a few minutes Jane put her hand on Maura's. Maura was still, unconsciously rubbing her thigh. "That's good," Jane said, a flush crawling up her neck. "I mean, that's fine. I mean, I think you got it."

Maura hadn't realized how long she'd been rubbing Jane's thigh. She pulled her hand back quickly, knocking into her own beer and sloshing some onto her dress. "Oh, shoot," she said. "Now this is going to stain, I'm afraid."

Jane reached over to swat the spot, realizing too late that she was brushing the back of her hand over Maura's chest. The spot on Maura's crimson dress spread as Jane yanked her hand away.

Naked Susie and her companions had raced back into the living room, Susie's team claiming victory over the loud protests of the other team. Everyone was sweaty and laughing as Susie led them over to Jane and Maura. Introductions were made, with Jane looking everywhere except at the naked people in front of her. Maura, however, inspected everyone, taking mental notes of body shape and confidence levels. She was enthralled by these naked people, interacting in a non-sexual manner, unashamed of their various oddities. They were having an exceptionally fun time, from what Maura could tell. Is this what she missed in college when she spent all those Friday nights studying?

"If you want to rinse out your dress, the laundry room is back there." Susie pointed over her shoulder. "I'm sure I have t-shirt and shorts you could change into. Though you don't have to, you know." Susie winked and scampered off with her friends.

"Oh my God," Jane said, whipping her head around to stare at Maura. "Is Susie flirting with you?"

"Of course not, Jane," Maura said, with a pshhh noise. "She's with Alex. Plus, I'm her superior. She's just being polite."

Jane made a face that said she wasn't so sure. This was followed by another face that said she wasn't sure why she was so irked that Susie might be flirting with Maura.

"Come on," Maura said, standing up and setting her beer down. She grabbed Jane's hand and pulled her from the couch.

"Oh, good," Jane said, relief visible all over her face. "Our ten minutes are way up, right? Let's go." She started for the door, but Maura hooked a finger in Jane's belt loop. Jane felt the resistance and stopped moving. Maura felt a little zing at having her hand so close to Jane's waistband. What was getting into her?

"I need to go rinse out my dress before we go. I can't let the stain set." Maura gave Jane a pleading look. "You can wait here for me if you want." She grinned at the thought of Jane standing as a clothed island in the middle of this sea of nakedness. Then she stopped grinning as she imagined Jane losing her shirt, and pants, and standing as a tall, sculpted island in a tank top and boy shorts. Maura's eyes glazed over and her mouth parted just a bit as she thought of Jane slowly tugging off that tank.

"Earth to Maura," Jane said, waving her hand in front of Maura's face. "There's no way I'm letting you leave me in this room all alone. I'm coming with you. And then, we're escaping."

Maura bit her bottom lip in frustration. How was this situation not the least bit titillating for Jane? Could it really be that she was on the completely hetero side of the Kinsey scale, and also a prude? Maura couldn't believe it. She wouldn't believe it. She grabbed Jane's hand and practically dragged her down the hall.

The first door she opened was definitely not the laundry room. Maura muttered a soft, "Oh, my," and Jane just openly gaped. A partially naked woman had a completely naked woman pressed up against a dresser. The partially naked woman was pounding several fingers inside the other woman as they both gasped and cried out. They had no idea anyone was watching.

"Jesus Christ," Jane whispered after a moment. Maura was reduced to just staring and blinking. Finally, she pulled the door shut.

"That was not the laundry room," Maura said, her eyes wide as she looked up at Jane. Her dimple showed as she grinned an embarrassed smile.

"Your detective work gets better everyday, Doctor," Jane said showing off her own dimples.

Maura rolled her eyes, laughed, and then grabbed Jane's hand again to pull her to the next door. This one she opened cautiously, peeking around it into a dark room. They were met with moans and wet, slapping noises. Maura shut the door quickly and quietly and turned to Jane who had her hand over her mouth to cover up her burst of laughter.

"So much for nudists not being sexually aware of each other." Jane snorted.

"Oh, that's not a fair statement," Maura countered. "It's a party. There's alcohol, loud music, abundant breasts. I mean, it's not like we're on a nudist hike or anything."

"Oh you think that'd be different? Face it, Maura. Susie Chang is a sex-crazed naked-person lover who has sex-crazed naked-loving friends." Jane was joking, but the joke stung Maura a little. She didn't like the over generalization, she didn't like Jane's tone.

Wait. Maura put her own hand to her mouth. The barbed sarcasm. The almost mean jokes. These were Jane's tell! Jane was having trouble working through something here. And it was more than just being surrounded by naked people.
