Author's Note: I know, I know... I said no more WIPs. But I started chapter 5 before I started posting this one, which means I can manage a chapter every few days and be finished by the time I catch up to where I am now, so I'm being good! Kinda. Anyway, I think this one will have 7 chapters, 8 at the most, and most importantly, no cases to get me twisted around!

This is a tag to 1x18, Rich's second ever episode of Blindspot. And yes, this is a VERY far-fetched concept, but I'm not going for realism or character logic accuracy, I'm just going for hotness. ;D If you don't like Allie, the idea of M/F/F threeways where the women are happy to touch each other, or Jane considering herself not committed to Oscar because she's only slept with him twice...I would recommend not reading or commenting on this fic.

And yes, I'm still turning my other fics over in my brain. :)

Allie Knight stared at her reflection in the bathroom mirror, and sighed. She'd made a stupid mistake, getting invested in Kurt Weller for a second time.

For a few days, she'd even believed she was getting closer to him than she'd been during their first try at a relationship. Getting to meet his father, sister and nephew had seemed a huge step forward, no matter what Kurt had said about it. And it had been a great dinner, until Bill Weller had collapsed and Kurt had had to rush him to the hospital.

But even though he showed no sign of withdrawing from their relationship, and their chemistry was still strong, it was pretty clear to Allie that she wasn't the only woman in Kurt's heart.

Not that he'd physically cheat on her. If there was one thing she knew for certain, it was that. Kurt was a stickler for rules, which was one of the things she loved about him. It made trusting him very easy. But Jane Doe—the woman with his name tattooed on her back, but no memory of how it had gotten there—had turned out to be Taylor Shaw, his childhood friend, who'd gone missing when they were kids.

And having her back—as a gorgeous, ass-kicking, intelligent woman who obviously had fallen head over heels for him—was a huge deal for Kurt.

She'd barely seen Jane and Kurt interact on their first case together—they'd been undercover, masquerading as a married couple of assassins, and they'd quickly been flown away from anyone tailing them. But Allie's first glimpse of Jane had been as she'd walked into SIOC in a stunning black dress. It had revealed practically no skin from shoulders to ankles, yet had made Jane look like a million dollars—or six million, since that was the value of the necklace she was wearing.

It hadn't been the necklace—which she'd been about to trade to Rich Dotcom for the stolen WitSec list Allie was after—that made Jane look so good. Nor had it been the figure-hugging but relatively chaste dress. Jane just happened to be slim, athletic and just plain hot. She'd make any outfit look great—and Allie had definitely noticed. Kurt in a tux and Jane in that dress would have made any bisexual think dirty thoughts about threeways.

But then she'd realised Kurt was completely tongue-tied, mesmerised by Jane's appearance and probably forgetting Allie was even in the room. Worse, Allie couldn't even hate her for it—Jane was obviously very uncomfortable in formalwear, and not even attempting to flirt.

Allie pulled a strand of hair back into place and frowned. She should have known right then that another attempt at a relationship with Kurt was doomed to fail. He'd even rebuffed her in favour of Jane's housewarming party at the end of the mission, when she'd asked him out for a drink.

She'd been honestly surprised when he'd sent her a text late one night, less than a week later, which had led to them drinking in her apartment—and then completely trashing the place as they'd clumsily stumbled to the bedroom, making out the whole way.

God, that was a great night. Sex with Kurt was always mind-blowing.

She'd made sure the way was clear before agreeing to date him—or at least, she'd thought she had.

I'm not asking for some big commitment—but I don't wanna play proxy to the woman you really wanna be sleeping with.

And he'd looked her in the eye and said, No. That's not what this is about.

She'd believed him—partly because she wanted to, but partly because she'd seen a flash of hurt in his eyes before he'd hidden it. She wasn't a hundred percent sure what the circumstances were—hadn't wanted to ask—but she'd inferred that he'd made a move on Jane and she'd turned him down, or some kind of miscommunication had happened, or that Jane was in a relationship with someone else.

Only, no matter what had gone wrong when he'd reached out, Jane's feelings about Kurt clearly hadn't changed. And today, when Rich had asked her about her dating situation, Jane had tensed right up. Allie was betting she couldn't remember ever having been on a date.

She scowled at the memory of Rich Dotcom's obnoxious behaviour throughout this whole case. He clearly had a crush on both Kurt and Jane, and as a result of the case when he'd thought they were married—when they'd arrested him and thrown him in jail—he seemed to be obsessed with the idea of a threeway with them. Kurt had told Allie about it, rolling his eyes, when she'd been about to take Rich into custody after the Hamptons case—and though today had been he'd been mostly focused on Jane, Rich clearly hadn't lost his fascination with the idea of Kurt and Jane as a couple.

Allie liked threeways. She'd had a couple of great ones—one of them with Kurt, and a woman they'd hooked up with at a bar once. But if Rich had actually been their co-worker, instead of a snitch who'd ended up using them to escape from custody, Jane would have been justified in suing for sexual harassment. He'd given Kurt a few appreciative glances, too, but Jane had been the one he'd really crossed the line with, while making it clear that Allie didn't meet his expectations for Kurt's girlfriend.

You two aren't actually married in real life? Because you had some serious chemistry back in the Hamptons.

Allie might have actually flinched at that, and Rich had obviously noticed. As they'd been commencing the art theft, he'd given his opinion on her relationship with Kurt.

So, you two are dating, huh? That explains why you're both so grumpy all the time. You're a terrible match. Way too similar. It's like trying to put a square peg in a square peg. Also, I'm pretty sure she's a lesbian.

Well, he'd been half right on that one. Allie was into women, though not exclusively. The square peg thing was a little unfair, though. She and Kurt had been getting along just fine, until this case.

Then, of course, there had been Rich's sneaky side conversation with Kurt while they'd been disarming the paintings. Maybe he truly hadn't meant for Jane and Allie to overhear that one, but the acoustics in the room had been very good, and both of them had been in range for it—Jane had studiously avoided looking at Allie the whole time.

So tell me again why you're not with Jane? Cause, I mean, every time something goes wrong—or goes right, for that matter—you look at Jane first. Not Allie. Jane. Some people might think it means you're more worried-slash-excited about Jane than you are about Lady Tommy Lee Jones over there.

And it was true. Rich Dotcom might have been deranged—and more than a little deluded about his own sexual appeal, unless Jane had been openly flirting with him in the Hamptons—but he was very good at reading the emotional undercurrents and body language of the people around him. He easily put into words what Allie had been struggling to contextualise all day, and as the three of them became less and less comfortable in his presence—and each other's—it had just given him more fuel.

Knowing full well that Allie was listening in on comms—along with the rest of Kurt's team—Rich had demanded to know what Kurt had said to Jane, back when he'd taken her aside to give her instructions for the mission. Looked really intense… He really seems to worry about you a lot.

Jane had valiantly tried to convince him that it was because they were part of the same team, and teams were supposed to look out for each other, but Rich had been unconvinced. It's for sure more than that, but hey, E for effort.

And Kurt had looked anywhere but at Allie.

She turned her back on her reflection and leaned against the bathroom counter, lost in thought.

It was over. It had to be. Even before Rich had flung himself from the top of the building, yelling that Jane should follow her heart and tell Kurt how she felt, Allie had known she couldn't just shrug this off. If Rich's words had all been bullshit, and Kurt and Jane had been laughing about it, the situation would be a totally different story. But everything he'd said—about Kurt and Jane's relationship, at least—had a ring of truth to it that she couldn't ignore.

The only thing keeping her from breaking down in tears right now was stubborn determination, because she really had started to let herself believe she and Kurt could last. Spending more than ten minutes in a room with him and Jane, though, had made things very simple and evident. She had to put an end to this, clear the way for Kurt to be with Jane.

And then eat a gallon of ice cream as she mourned the loss of what could have been the greatest relationship of her life. It was obvious what she had to do, but it would hurt like hell. Then again, Allie was an expert at ripping Band-Aids off her problems.

The only thing that made her pause was that Kurt was his own worst enemy in relationships. He didn't open up much. He was far more likely to ignore a problem than to talk it out, until that problem got too tangled to be unravelled. Even if she flat out told Kurt that she was leaving him because he was in love with another woman, Kurt would tell her he'd chosen to date her, not Jane, and that would make Allie feel like she was being melodramatic.

If Kurt had already attempted to get with Jane and been rebuffed—which Allie was pretty sure Jane now regretted—not only would Kurt not want to talk about it with Allie, but he'd build up one of his big emotional blockades to try to convince himself that he didn't want Jane anyway. It was textbook Kurt Weller behaviour—and good luck to Jane trying to drill through that wall.

Not only that, but if he tried to convince Allie that she was the one he really wanted to be with, she might actually believe him. She was usually practical and level-headed, but Kurt could turn her brain to mush. He needed to get with Jane for his own good, and hers.

Oh, god. Allie was planning to leave him, but his father had terminal cancer. She didn't want to leave him feeling alone and rejected during a terrible time in his life.

Maybe…maybe Rich had been onto something, when he'd joked that Kurt could 'get a little holy trinity going' with Allie and Jane. Not that any of them would ever want Rich to find out. He'd be insufferable.

But if she could make Kurt and Jane see that they should give each other a chance, at least Allie wouldn't feel so terrible at leaving Kurt during this crisis he was having. Plus, she'd get to have a little fun with Jane, which held a certain appeal.

Why can't you hate Jane, like any other woman would?

Maybe it was because Jane wasn't getting territorial over Kurt, or scheming to take Allie's place. Allie had been approaching the lab, earlier that day, when she'd heard Jane awkwardly attempting to express her support to Kurt over his relationship with Allie.

And Kurt had not known what the hell to say in response, which was just another sign that Allie was in the way.

But hey—even if Jane wasn't bisexual, she'd told Kurt she found Allie beautiful. Allie had tempted women into bed by using nothing more than their curiosity and her own charisma before. Maybe this would work out.

You can be sad that you're single later. For now, it's time to go out with a bang…so to speak.

Kurt looked around the penthouse where their confused standoff with ISI had taken place, shaking his head. He'd known something like this would happen, but Allie had decided he thought she couldn't do her job, and Mayfair had overruled him, so here they were, with a fugitive on the run and eleven priceless paintings unaccounted for.

The past two hours had been filled with statement-taking—he, Allie and Jane had rounded up the terrified party attendees, in the hopes that one of them could confirm that Sho Akhtar had been the guy shooting golden pistols in the air while dancing. Failing that, they were hoping someone else at the party had been in on Rich's plans, and might be willing to betray him. It was a vain hope, but they had to try.

Kurt had just gotten off the phone with Mayfair and Patterson, filling them in on the results of their questioning—essentially, nothing—and getting an update from Patterson about the FBI/Marshals joint manhunt for Rich and Boston. Reade had liaised with ISI in Urdu, then he and Zapata had escorted an unconscious Akhtar—if he even was Sho Akhtar—back to the NYO.

The crime scene techs were hard at work now, and Kurt rolled his eyes at the sight of one golden pistol being carefully bagged and tagged. It stood to reason that any of Rich's criminal underworld associates would be as outlandish as he was.

The penthouse elevator dinged, and Kurt turned to see Allie stepping off it. They'd been using empty rooms on the floor below to take witness statements—it was easier than carting a bunch of drunk, stoned partygoers back to the NYO—and had agreed to meet back here when they'd each finished their tasks.

"All done?" He resisted the urge to embrace her, not wanting to look unprofessional in front of the CSUs, but he brushed his hand over her arm for a moment.

Allie smiled, looking a little wan. "Guess you can't really say we're done until we track down Rich, Boston and those paintings. But something tells me they'll be in the wind for a while yet, so yeah, for tonight, I'm done."

"I just got off the phone with Mayfair. No sign of them yet."

Allie rolled her eyes. "It's okay, you can say, 'I told you so'," she said. "We should have listened to you. You were the one who arrested him last time. You had a better idea of what he was like than we did."

It was tempting, but she was obviously feeling down about the way the case had turned out, so he tried not to rub it in. "It could have gone either way. If not for that damn tuxedo, we would have still had him. How's your head?" Allie had been briefly knocked out earlier in the day, as she and Jane had fought Turner.

She rubbed the back of her skull. "Got a goose egg, but at least the bruise is covered by my hair. No lasting headache though, so I'm good. Just stressed and pissed off."

Kurt nodded. "Same here. We can get out of here now, though. Any sign of Jane down there?"

"The room she was using was empty when I looked, and she wasn't in the bathroom I just used, either." Allie frowned. "Think she's okay?"

"Hope so." He called over to the nearest tech, "Did Jane Doe come back up here?"

The guy looked up and frowned. "Uh, yeah. She said to tell you she's on the roof. We've finished up there already, so…"

"Thanks." Why would Jane be up on the roof?

"She a smoker?" Allie asked.

"No." He shrugged, turning towards the door to the stairwell. "I'll go get her. Back in a minute."

"It's okay, I'll come with," Allie said, and he glanced back at her, wondering if she was feeling insecure after all of Rich's comments that day.

They were going to have to talk about that. But not now; not until they'd dropped Jane off at her safehouse and got back to Allie's apartment.

Allie followed him up the stairs, which doubled back on themselves halfway up, but just before he reached for the door, she grabbed his hand and tugged him further into the corner of the small landing.

Puzzled, Kurt blinked down at her as she leaned against the wall, tugging him closer by his belt buckle. With a quick glance up at the frayed wires where a camera used to be—evidently, this place was used by many a couple seeking privacy—he asked quietly, "What's up?"

Allie pulled him down into a teasing kiss, and he indulged her for a moment, confused, but enjoying the moment. Then he drew back.

"As much as I'd love to take this further, I lead my own team these days. Getting caught would kind of undermine my authority, so…rain check until we get home?"

Allie gave him the unashamedly flirtatious smile guaranteed to melt his brain. "I have a proposition for you."

He remembered those words from years ago, just before she'd suggested they bring a woman home with them for the night. Now he was truly surprised. "If it's the same proposition as last time, I'm not saying no…but after the day we've had, do you really want to get dressed up and go out looking for someone?"

"We don't need to. There's someone right outside this door we could lure into our bed."

Kurt froze, his mind and body both stalling in complete disbelief.

Allie was too busy kissing his neck for him to see her expression, but she laughed against his skin. "Relax, Kurt. It's pretty obvious you're into her, and honestly, I can see why. And after the day we've had, I think all three of us could use a little stress relief, right?"

Between her kisses and his imagination, he was getting steadily more stressed by the second. What the hell was she thinking? He'd expected Allie to be upset after everything Rich had said about him and Jane, to have to convince her that even though he and Jane had a little chemistry, he was happy in their relationship and not looking to change anything. But instead, she was hoping to bring Jane home for a night?

She was confusing the hell out of him. Not to mention turning him on.

Gently, he extricated himself from her embrace enough that he could look into her face.

"Allie, I don't think it's a good idea. Not with Jane."

Allie rolled her eyes. "Oh, come on. I think we'd have fun. It's just one night. You can get her out of your system, and it's been forever since I've been with a woman."

"I'm not good enough for you on my own?" he teased, though he was feeling anything but amused.

He had to talk her out of this idea. Jane was off-limits.

"You already know you are. But every now and then, it's fun to switch things up a little, and she's right out there. We could have her naked on my bed in thirty minutes." Allie wriggled against him, then slid her hand down to rub his hardening cock through his jeans. Her smile grew. "Oh, you like that idea, huh?"

Kurt swallowed a groan at the idea of watching Allie strip off Jane's dress. "It's not just that I think it's a bad idea. Which it is. The other woman we took home was someone we haven't seen since. I have to work with Jane every day."

Allie kissed him, provocative now, and he pressed her back against the wall, unable to help himself. For a few seconds, he forgot himself and kissed her as though he planned to fuck her right then and there—but then he remembered where they were and pulled away, breathless.

"You were saying?" Allie prompted, amused.

Kurt grabbed her wrist to stop her teasing pressure against the front of his jeans. "Hard to think when you do that."

Allie brought her hand up to rest on his shoulder. "I'll be good. What was your point?"

He'd had a point? It took him a moment to unscramble his thoughts. "My point was that if we suggest it, Jane will turn us down."

"You think so? Because I was coming down the hallway to find you guys, and I heard Jane tell you she thought I was beautiful, smart and tough, and she could totally see the appeal of dating me."

Shit, she heard that? Awkward. Except…apparently not.

"I don't think she was talking about wanting to date you herself," he pointed out.

"And that's good, because I don't want to date her either. I just want to make her come a few times." Allie looked up at him mischievously through her lashes. "And watch you make her come a few more."

Fuck, fuck, fuck.

Kurt closed his eyes, wondering how the hell he was gonna get out of this situation. He couldn't just walk out on the roof, ending the conversation with Allie, because he was too obviously turned on. But she wasn't gonna let this drop without a fight.

"I don't think Jane is into women." He didn't have any evidence that she was completely straight, either, but he didn't say that.

"I didn't think I was into women either, until I was at Quantico and one of my classmates hit on me. Bet I could convince her to at least try me out." She pulled her phone out of her pocket and checked the time. "If we don't go find her soon, she's gonna come looking for us. So what's it gonna be, Kurt?"

He stared at her, indecisive. He'd already resigned himself to the fact that Jane regretted their kiss outside his apartment building. She hadn't shown up at the park when he'd asked her to come and discuss it with him, the first free evening they'd had after that. She must have had second thoughts. And that was fine. She hadn't chosen the best way to let him know that, but he could deal.

On the other hand, she knew he was dating Allie these days. If they did persuade Jane to come home with them, it would be for one night only, a no-strings-attached deal. Maybe Jane had decided a relationship would be too much for her, but she could handle a one-night stand.

Fuck, I don't know if I could handle that. Knowing what she's like in bed, but never being able to touch her again…it would be too much. No. It's not worth it.

"I'm pretty sure she's wearing real stockings under that dress. We could get her into the car. You could drive, and I could pull her panties to one side and go down on her in the backseat."

"Fuck, Allie," he groaned, resting his forehead against the wall above her shoulder.

"Or I could drive, and she could give you head."

He tilted his hips against her, unable to help himself as his imagination supplied all the details. Those big hazel eyes gazing up at him as she sucked his cock… God, could he really say no to that?

Allie laughed, palming his cock through his jeans again. "You might as well just give in. What's the worst that can happen? She says no, it's a little awkward, and then we all never speak of it again."

No. That she says yes, that we have an amazing night, and then we have to pretend it never happened, that we don't want it again, and again, and again.

What sounds would she make as he thrust into her for the first time? How would her tattoos ripple and shift as she arched with pleasure? Could he bear to not find out?

Kurt knocked Allie's hand away from his cock. "I can't walk out there with a hard-on, no matter what we plan to do."

"True. Though it is a fun image." Grinning, she shimmied out from between him and the wall. "So here's the plan. I'll go out there, test the waters a little…"

This is a really bad idea.

But it was a bad idea he was craving more and more with each moment that passed. At first, all he'd wanted was to change Allie's mind, but now, he didn't know what he'd do if she decided to back out.

As Allie finished outlining her plan, Kurt hesitated. "Okay. But if she says no…"

"It was all my idea and you didn't want it anyway?" Allie gave him a knowing look.

"I have to work with her," he reminded her again.

"I know. I get it." She smiled hopefully. "So is this a green light, or do you want to use your safeword? Because if you don't want it, I don't want it."

He snorted. "You just spent the past five minutes trying to convince me."

"That's because I know you'll love it. But seriously, if you want me to stop pushing—"

He kissed her, quick and hot. "Just go on out there before she comes in and ruins your plan."

Please don't let this be a horrible mistake.
