A/N: There's a reason I said no more threesome stories: I can't seem to write them in the form of a one-shot. But I ended up writing another Brenda/Sharon/Andy story.

Special thanks to imafrakincylon, challenging the world, and Maura for reading through this for me when I was doubting myself.

–

It was supposed to be a simple dinner out with Andy on her birthday. They were only going to that Italian place where the owners knew their names, maybe stop at that little caféshe liked that had the dessert she would allow herself to have on special occasions, and then they were going to go back to her place. It was almost routine. Her birthdays for the last ten years or so had been spent that way. But when they were walking down the street, lost in both conversation and their thoughts of what they knew would be happening once they were at her condo, they hadn't expected to bump into Brenda Leigh Johnson.

She was walking out of the café they were about to stop at to pick something up from to take to her place. She looked like she was just as surprised to see them as they were to see her. Surely her surprise had more to do with them being together than anything else. There were only a few people that knew they were at one point friends – nobody knew that they were much more than that in reality.

"Cap'n- Uh, Sharon, Andy," she said, her accent thickening as she flustered.

Andy smiled, stepping to the side to let another person into the café. "Chief, what are you doing all the way over here?" he asked as he looked over her. She was still wearing the floral dress she had on earlier, but he was certain she had left work a few minutes after he had – which was hours ago. She also lived on the other side of Los Angeles, so it was a complete shock to see her.

"I was just," she held the bakery box up as she smiled and shrugged sheepishly, "I found out they have the best brownies here. And what 'bout you two?" She left out the part about asking why they were together. She had already read into the way Sharon distanced herself from Andy when she saw them.

"We were out having dinner together," Sharon answered with a polite smile.

Brenda nodded, her eyes quickly looking over Sharon. She was wearing her navy trench coat, but she could see a little red peeking out; she could only assume it was a dress. On her feet were a pair of expensive stilettos, a little higher than the type she would wear at work. "Ooh, how nice. What's the occasion?" For some reason she couldn't exactly see them going out on a date.

Sharon was about to answer, but Andy beat her to it. "It's her birthday," he answered quickly.

Sharon narrowed her eyes as she balled her fist in her pockets. Brenda didn't need to be in her personal life more than she already was. It was bad enough when she couldn't do things – like buy chocolate or walk by one of those stores that showcased ugly floral dresses – without being reminded of her; she didn't need Brenda also knowing more about her than necessary.

Brenda smiled widely in Sharon's direction. "Happy birthday." Sharon thanked her as she looked past her and into the café. "I guess I should let you two..."

Sharon only smiled politely. She didn't want to seem rude, but she really did want to quickly grab what they came for so they could get to her condo. She only allowed herself a few of the nights of the year with Andy, and she didn't want to lose out on more time than she already had.

Andy must have been completely oblivious to what Sharon was thinking, because when he told Brenda they were just going to grab something and she should join them, that was the last thing Sharon wanted to happen. Just like that, her routine birthday plans had been altered, making her wish she had just skipped dinner and dressing up all together. If she had known he was going to waste her valuable time on talking to Brenda, she wouldn't have spent so much time going out of her way to do a little extra than she usually did. It was all being wasted under her trench coat, anyway.

"You wanna just stay here for a little while?" Andy whispered in her ear as they were inside the café.

Sharon glared at him for a moment before she spoke. "No, I do not want to stay here for a little while," she said in a sharp whisper. "I would like to get home."

Andy rolled his eyes at her and turned to Brenda, who was leaning against the counter space where a few things were being showcased. Brenda smiled at him, her eyes sparkling in the dim light. He looked back at the guy who was boxing their things for them and then to Sharon. "I just thought you would like to do something other than what we always do. Forgive me for trying."

"Have I ever complained about how we usually spend my birthdays? I actually look forward to them."

Andy looked at her with a disbelieving look. "Things have changed since your last birthday," he whispered. She gave him a look that told him to just go ahead and spit out whatever he was getting at. He turned fully into her so Brenda couldn't see him as he said what he had to say. "I thought you might like to spend some time with the chief as well. The last time we, you know, it was because of her. So I was only-"

"'Scuse me?"

Andy grunted. This wasn't coming out how he expected. He just wanted Sharon to know she didn't have to hide certain things from him. He could already see most of it on his own. "The last time was after that argument you had with her," he reminded her. "You hadn't called or anything, and we both know that's not like you." He watched Sharon purse her lips, clearly trying to come up with something to say. He went on when he realized she hadn't come up with anything. "You don't have to admit that the only reason you showed up that night was because of everything that happened with the chief. Just know that I know."

"Here you go, sir," the guy said to Andy, holding out his bag for him to take. Andy thanked him as he took the bag from him.

Sharon hadn't said anything to Andy as he walked them over to Brenda. She was still trying to figure out how he figured it out. She was certain whatever kind of ridiculous attraction she was growing for the infuriating woman was something she hid well. And how had he seen through all the animosity and, dare she call it, childish behaviors that had covered up the sexual tension she had noticed? These thoughts were on her mind as Andy and Brenda talked about something. She joined in the conversation every few lines, saying a few things, but really she was too focused on her internal conversations.

While idly nodding and humming, Sharon ended up agreeing to Andy and Brenda's idea that it would be a good decision for Brenda to come over for a drink as they continued to talk about whatever it was they had started talking about. Sharon wasn't sure if she was more annoyed with herself for not paying close enough attention to the conversation, with Andy for thinking it was a good idea, or with Brenda for batting her eyelashes as she smiled widely at her. Either way, the three of them ended up at Sharon's condo, Sharon and Brenda sipping wine as Andy drank his usual cranberry non-alcoholic drink he put together. And for a while things weren't so bad – if you didn't consider the fact that she had really been looking forward to the more physical part of the evening.

After Sharon told Brenda where the bathroom was, she turned to Andy, who was sitting on the armchair, watching Brenda walk down the hall. "So what's the plan?" Sharon whispered, her tone not showing her annoyance.

"Huh? What plan? What are you talking about?"

"Don't pretend to be confused," she said slowly. "I've known you long enough to know when you have some ridiculous idea moving through your head," she told him, watching the grin on his face drop.

"I already told you, I thought you might like..."

"Bullshit," she interrupted, the word pronounced precisely. She looked at the time and then at Andy. "It's almost ten o'clock and that woman – Brenda – is still here. Either tell me what you expected to accomplish by bringing her here, or the both of you can leave once she gets back out here."

Andy could tell she was serious. Leaving was one of the last things he wanted to do. As he tried to figure out how to explain to her what he had in mind, he realized he hadn't thought everything through, as usual. It all made sense in his head. Get Brenda to Sharon's place. Maybe get Sharon to realize that she wasn't the only one trying to hide their sexual attraction – he really didn't understand how she didn't notice the wide smiles, not-so accidental touches, fluttering eyelashes, lingering looks, or all the other things Brenda wasn't that good at hiding. Maybe once Sharon realized all of this, then everything else would fall into place. They had discussed having a threesome with another woman before, fantasized about it openly while having sex, so he didn't think it would be that far-fetched. That was until he was looking at Sharon glare at him as she waited for his response.

Brenda walked down the hall, smoothing her hands down her dress. Andy and Sharon were silently staring at each other and she was sure she was interrupting something when she walked back into the living room. She looked at the time quickly before sitting down, crossing her legs as she faced Sharon on the sofa. Sharon didn't turn to her – which may have been a good thing since her eyes were drawn to the low neckline of the red dress Sharon was wearing. Brenda's teeth ran across her bottom lip as her eyes discreetly moved across Sharon's body, tracing every alluring curve and line she could within the few moments she had.

Sharon shifted in her seat, but she didn't let Brenda know she could feel her eyes on her. Her skin was tingling as if someone was touching her. It burned pleasantly and was making sitting beside the other woman slightly uncomfortable. The look in Andy's eyes let her know he knew Brenda's gaze was affecting her – he really did know too many of her tells. She was still waiting for an answer from him, but she knew she wasn't going to get one now that Brenda had come back. She tried to put pieces together on her own instead.

From the moment they had walked through the door, Andy had taken on a different mood. Andy's flirtatious manner when they were alone was something Sharon was used to, but seeing it directed at both her and Brenda was new. She wasn't an idiot; she'd known for a while that he liked Brenda more than one should like their boss. She also had caught Brenda smiling a little too hard while looking at Andy. She wondered if any of that had anything to do with why Andy had brought Brenda with them. The fact that they were going to have sex after dinner was not something they had to talk about – not only was it the norm, they had also been teasing each other in the most innocent ways through dinner. So she wasn't sure why he would have been getting her ready for something that wasn't going to happen.

"Andy, can I see you in the kitchen for a moment?" Sharon finally asked when nobody had said anything and she thought she had figured out what was going on. Andy stood and she turned to Brenda quickly, excusing herself with a smile and a hand gently placed on the smaller woman's thigh. She almost missed the way Brenda's breath rushed through her lips at the contact.

In the kitchen, Andy looked at Sharon with questioning brown eyes. "What?"

Sharon looked out the kitchen and then turned her back away from the living room, her voice low enough for him to hear her and Brenda not to. "You've done a lot of stupid things before. A lot. But I don't think you've ever done something this stupid. If I'm wrong about... I hope I'm wrong." She could tell by the look in his eyes that she wasn't and she hadn't even told him what she was thinking. "You really thought it was a good idea to bring your boss to my house to, to...?" She couldn't even say it. The vivid images that flashed through her mind weren't something one could really summarize in a word or two. "You didn't even run this by me, let me know what you wanted. Do you..."

"You plan on letting me explain this to you, or, what?" She made a hand gesture as she straightened her back, her hands resting on her hips as she waited. "No, I didn't think this through. And maybe I didn't talk to you about it first." Andy ran his fingers through his silver hair as he leaned back. "But I was only thinking of you when I-"

"Don't you even!"

Andy caught Brenda turn around with a questioning look in her eyes. He licked his lips as he looked back at Sharon, unsure if she was as upset about it as her tone was suggesting. "It's not like we hadn't talked about this before. You said multiple times that you wouldn't mind a threesome."

"Not with her! Not with your boss. Not with someone I work with."

Brenda got up from the sofa and went into the kitchen, unable to just sit there and pretend she didn't know what was going on. Her hearing was far too good for that. "Is everythin' okay?" Brenda asked even though she knew it wasn't.

"Yes," Andy answered as Sharon answered, "No."

Brenda hummed, licking her lips, looking at Sharon. "What's the problem?"

You, was the answer her mind screamed. "It's just getting late," was what she said aloud.

Sharon was a horrible liar, but Brenda didn't call her on it. "Maybe I should get goin'. I wouldn't want to ruin the rest of your night together."

Sharon schooled her features and didn't react to the comment like she knew Brenda wanted her to. "That sounds like a good idea."

"Sharon!"

Sharon glared at him. He couldn't seriously believe she was about to sleep with her. Did he even think about what Brenda would think of the idea? Did he think she would want to sleep with either of them? He didn't seem to be affected by the glare like she hoped.

"Don't you think it would be a good idea to at least consider..."

"No, Andy," she insisted.

"Consider what?" Brenda said, sounding clueless even though she was already considering the proposal as if they had asked her already.

"It's nothing," Sharon tried, but she could tell by the look the blonde was giving her that she wasn't going to let it go. Sharon briefly wondered why she was always attracted to people who always felt like they had to get what they wanted, whether it be the answer they were looking for or a threesome with a woman she wasn't even supposed to like.

"It must be somethin' if it's causin' such a fuss. Why don't you tell me? Maybe I can help," she said in a voice that was far too innocent for it to even convince herself. Sharon's arched eyebrow made her smile even brighter, cocking her hip out as she leaned against the breakfast bar.

Andy watched the interaction between the two women. Sharon's eyes, as if she hadn't even had any control over them, moved to the curve of Brenda's hip and ass, her tongue slipping out to run between her lips. He wondered how Sharon could even act like she didn't want to sleep with Brenda. When Sharon looked up, looking between him and Brenda, that hungry look was starting to take over her green eyes. Brenda was no different. If Andy was affected by the little things Brenda was doing, the way her voice seemed to take on a quality he hadn't heard often from her, then he was sure Sharon was as well – he was also sure that was what Brenda intended.

Sharon let out a shaky breath and then took a step back. "I think you should both leave," she finally decided. She wasn't about to make a fool out of herself, so there was only one way to end the night.

"What?" Brenda spat out, shock evident in her voice – too much for a person who wasn't supposed to know what other possibilities the night had in store. "I mean..." Brenda felt her cheeks warming, most likely an embarrassing flush coloring her skin.

Andy raised an eyebrow at her and cleared his throat. "Sharon, are you sure?"

Sharon was still trying to read into Brenda's reaction to think straight. This was not how she expected to spend the night of her birthday. "Yes," she finally answered. "I think it would be best if we were to call it a night." She looked up to meet two pair of disappointed brown eyes. "Maybe we can do this again," she added, hoping to make her response sound a little better.

Brenda was leaving first; Andy had decided to stay back and see if he could change her mind about him staying. Sharon walked her to the door, and before she could open it, she felt Brenda's hand on her arm. She looked at the smiling woman and was surprised, pleasantly so, to feel her lean in and hug her. Sharon wasn't much of a hugger, but she decided to return the hug. Brenda's hair had the fading smell of flowers, her small body against her own was something she admittedly enjoyed (maybe a little too much if the way her skin instantly warmed was a clue), and when she felt Brenda's eyelashes flutter against her skin, it made her tingle.

"Happy birthday," Brenda said directly into her ear, her breath warm against her.

Sharon swallowed thickly when she felt herself tremble slightly, the sensation moving through her entire body, sending arousing jolts to her core. She pulled away from the hug, knowing Brenda must have felt it as well. She blamed Andy for her hypersensitivity – not only had it been much longer than usual sinse they last slept together, but before they left for dinner he had taken advantage of the extra time they had since he was early, therefore, leaving her aroused once they had to leave.

Brenda was reluctant to pull back, but she did with a smile. She looked at Sharon fast enough to catch that flash of something new move through her usually unreadable eyes. It was the only thing she needed to know that she hadn't misread and misheard everything earlier. If possible, her smile only grew as she tucked blonde hair behind her ear and turned back to Andy for a moment, trying to figure out how to do this correctly. As Sharon reached for the door again, ready to open it, she realized there was no correct way.

"Wait," Brenda insisted, impulsively reaching out and putting her hand on Sharon's, stopping her from opening the door. Sharon looked at her questioningly. She was still trying to figure out what to say when she realized she couldn't just stand there, holding Sharon's hand, trying to get her thoughts together. So she had to come out with it. "I know what you wanted to ask me, or, well, what you didn't want to ask me. And, and, and I think..."

Sharon pulled her hand away as if it had been burned. She was almost sure her heart had stopped beating for a moment as she took a step back. The reaction made Brenda stop speaking as she bit her lip, most likely wondering if she should have just left and let it go.

Andy got up from the sofa, realizing what was going on. He started walking over to them, knowing Sharon wouldn't respond to what Brenda said if she wasn't clear about what she knew. But apparently his presence was needed to make it clear.

Brenda stepped closer, almost closing the space between them. Sharon narrowed her eyes, looking like she would move back, but she didn't. Sharon stayed there, waiting to see what she would do next. Brenda smiled, tilting her head as she licked her lips so slowly that she could follow Sharon's eyes as they followed her tongue. This was new without really being new. They had moments like this before, but Brenda had ignored it when she was sure Sharon wasn't really aware that she was reacting to certain things the way she was. She also wasn't sure rule-loving Sharon Raydor was really attracted to her the way she was hoping she was.

"I'd stay if you asked me to," Brenda whispered, coming closer.

Sharon felt her heart pounding as she fought the urge to move away. Brenda was so close that she could feel her again, her hot breath on her lips, and her body touching her own. Sharon's head was spinning as she continued to silently look into lustful brown eyes. She'd never seen Brenda's eyes like this – they were much darker and drew her in even more than they normally did. Sharon licked her lips as she felt them going dry, but her mouth also felt dry and nothing was helping.

"Is that what you want?" Brenda asked, her free hand tentatively brushing hair off the side of Sharon's face. Her fingertips lightly touched her, softly and slowly.

Sharon caught Andy's eye, but he only grinned at her, waiting to see what she would do. If only she knew what she would do. Maybe if she knew, then her heart would slow down and her breath would even out. Instead, as she looked back into those lustful brown eyes and then to inviting lips, she felt her body only react more erratically to Brenda. She could drown in the amount of desire that was surrounding her. And if Brenda didn't go ahead and kiss her, she was sure she would actually stop breathing. Her lips were so close, her breath so hot on her lips that it burned. But she still hadn't closed the space.

"Yes," Sharon heard herself answer the question she had finally processed.

Everything happened so quickly that she could hardly figure out how Brenda's lips ended up on hers, softly pressing against her own. The hum that she felt in her throat was one out of both shock and pleasure. She didn't close her eyes; she looked over to Andy, watched him as Brenda's lips started to move against hers. She didn't know what was making her heart beat faster: the way Brenda's hand weaved through her hair and pulled her closer to her mouth or the way Andy watched, eyes practically glued on them.

Brenda pulled back from the kiss, her teeth lightly clamped on Sharon's bottom lip, making her moan as she pulled on it. Brenda smiled at her as she finally stepped back, sure if Sharon and Andy really wanted her to stay, which she hoped they did, they understood they had nothing to worry about. She looked over her shoulder, smiling at Andy before she licked her lips and turned back to Sharon.
