Author's note: Although this is technically not a song fic, I have been usually running the first portion of the dance sequence through my head to either Lights by Ellie Goulding or Don't you Worry Child by Swedish House Mafia. Both have the pace that would be appropriate for the description and both also have a section of the song that slows and picks back up again. The second song featured is Cosmic Love by Florence and the Machine. I feel it is very fitting for the Ianto/Jack vibes. It has a more masculine, powerful feel to it, and even the lyrics are quite fitting. So you can skip it or play it or play something else that you like, just thought you may like to know the original inspiration. Hearing those songs on my car radio kept pushing me to compose this whole fic. Both are available on youtube.

The doctor, the captain and the ex-cop all noticed it at the same time. Three sets of eyebrows simultaneously sprang up out in the parked SUV. On the computer screens they all saw Ianto suddenly straighten his posture as he snapped Tosh flush to his chest. His pale hand flexed against the almond-hued skin of her back, framed by the blood red silk wrapped down her ribs to the small of her back. Toshiko's gloved hand caressed her partner's neck and strayed into his hairline. The start of the song was a sexy and slow build. There were a few sensual, languid steps. Tosh then wrapped her outer leg around Ianto thigh and only their hips moved...but oh how they moved.

Jack unconsciously reached over and rolled his window down a bit and unbuttoned one button on his shirt.

Owen swallowed hard.

Even Gwen felt the need to unzip her leather jacket.

The the music picked up and so did the dancers. With every beat of the ever-quickening pace of the song the two spun - suddenly apart and then suddenly together again. They never missed coming back to hand in hand and hip to hip. Next Tosh was turning with a hand around her waist, then it was deftly switched to a commanding hand on the back of her neck that she leaned trustingly back into as Ianto supported her. With this their knees both bent and her skirt hitched up slightly due to the presence of Ianto's thigh in between hers. The two were then spinning together again with intricate interweaving footwork, eyes locked on one another.

The thick silence in the SUV was broken as the woman in the backseat exclaimed "Wooh! Would you look at them go! Bloody hell they're fantastic!" She beamed with awe a the screen and gestured excitedly.

The two men in the front seat jumped at Gwen's sudden yelp, but at least it prompted both of them to stop their matching impressions of gaping frogs.

Jack recovered and cleared his throat. With his usual frisky grin he said "Told you he could dance."

The doctor's eyes didn't leave the screen. "She's not too shabby either." he replied, a bit deeper and throatier than he intended.

Gwen glanced between her two transfixed co-workers with a smile. She then started clicking through the different views of the action that the CCTV patch offered. She studied her friends and the major competition on side by side screens. The other couple was keeping pace, and the blonde was making good use of those long legs. The shirt on her partner looked as if it would give way any moment under the strain of his muscles.

"Jack, Owen, that other couple is going to give them a run for their money."

The two men gained their composure and got focused back on the task at hand. Through the views from the contact lenses on Ianto and Tosh the team could also see that they were each stealing glances at the competition. The dance floor was practically empty now save for the two couples.

"Ummm, is Torchwood 3 involved in a dance-off?" Owen queried with an air of disbelief.

"It would appear so." replied Gwen.

"Right..." Owen drawled as he tipped his head sideways to make out the dizzying action playing out on screen.

The music's frenzied pace then came to a bridge where the base fell away and there was a pause, the melody in the background hinted that it would spring back to life momentarily. When the song reached this point the opposing couple took to moving against each other like pure vertical sex, while Ianto had opted the cooler option of snapping Tosh out away from him. She spun around him with such fancy footwork that she resembled a gold-medal ice skater. He stood regally and, somehow still in sync with the music, straightened his waist coat, stretched his neck, and shot the other couple a dismissive up and down look. Without even looking at Tosh, Ianto extended a hand and caught her hand in his, ceasing her spin by drawing her into a deep embrace that quickly turned into a dip. Then they were off and running again.

Jack finally chimed in, his voice laced with frustration "They are playing this wrong. This isn't about competing with the skills of the other couple. This is about seducing the Brookfields. I hate not being able to see their reactions to things!" Jack smacked the side of the computer screen in frustration.

"I'm going in." He declared resolutely. "I need to see what the Brookfields are responding too. Being able to read what people like...well let's just say that's something I am well-versed in. Let me just sync my wrist strap to send Ianto and Tosh directions. But for now you two stick with their original plan and don't break their concentration by texting across their eyeballs unless its really important. Got it?"

Gwen and Owen indicated their agreement. Jack set out immediately in a swirl of billowing coat. They watched as he approached the emergency exit in the alley, tapped a few keys on his wrist strap, and slipped in the disabled door.

Jack made his way into the throng of the crowd, but hung back far enough to not attract the attention of his team on the dance floor. Ianto and Tosh were whirling and occasionally writhing, sharing the spotlight with the tall shiny couple. Jack silently observed that, although the couples were well-matched in their talents, the blond and her chiseled partner were more into using the dance to show off their physical assets than truly feeling the music. Ianto and Tosh had a classier grace to them. Their dance fit their personalities. Their posture, timing, and precision was outstanding, and yet they improvised well and trusted one another completely. But of course that was the case. These two people had been through several near apocalypses together and routinely watched each other's backs in life and death situations. Toshiko and Ianto were each in their own way a perfect balance of beauty and intellect.

Jack caught himself in his wistful complimentary revelry and got down to the task he came in for. He reluctantly shifted his attention to the Brookfields. The attractive couple were already on their feet, just inside the perimeter of the VIP section. Each clutching a crystal flute of champaign, Jeremy had his arm around Elena's waist and she was snuggled close enough to his side for them to whisper to one another, but their attention was clearly on the dance floor. Jack followed her gaze. Her eyes flitted between the two couples and she seemed to be pleased with both. She would turn to her husband for a chat and look where he directed her. Ah! Thought Jack. She is happy with either set of contenders and will defer to his choice then. So who do you fancy Mr. Brookfield?

Jack followed Jeremy Brookfield's eyes as the proprietor of Needful Things unabashedly licked his lips. It didn't take Jack's trained eye long to catch it. Whenever one of the couples moved apart briefly in their dance, Jeremy's eyes consistently followed the male's movements. When he watched the statuesque man dancing with the blonde, Jeremy was clearly impressed with his muscular physic. His eyes widened as the man easily lifted his partner, causing his back to ripple under his skin-tight shirt. But as the two couples maneuvered in such a way that Ianto and Tosh twirled in Jeremy's line of sight again, his eyes followed the black-clad Ianto. When the Welshman moved his hips Jeremy Brookfield tilted his head and a small smile spread across his lips that gave him the appearance of being positively tipsy, but Jack suspected it had more to do with Ianto Jones than the glass of champaign. Jack knew from experience. If he let himself stare for too long he would probably be wearing that same look.

But the problem was that Ianto wasn't returning the lustful look, and so Jeremy went back to admiring the taller eye candy. The blonde partners seemed to love the attention of the Brookfields and, although their dancing technique suffered for it, they were playing it up and blatantly flirting back. So it was becoming a battle between the preening peacocks and the black swans.

The DJ deftly slid the upbeat dance to a more progressive sounding tune. The vocalist had a haunting voice that Jack briefly noted as having similarities to the style that was popular in the Andarian Quadrant when he had the pleasure of visiting that part of the galaxy in his time-agent days. Although the singer was a female the music had a decidedly strong male vibe to it. Jack wondered if the DJ was mildly empathic and read that this would be fitting for the show down that was playing out.

So it would come down to Ianto then to focus some receptive attention on Jeremy Brookfield if the Torchwood team was going to be successful on their mission. Jack looked to Ianto to see if he was also picking up on this as well.

Jack's breath caught in his chest when he felt Ianto's piercing blue eyes focused on him. Even with Jack tucked away in the shadows of the crowd Ianto had found him. Although he was still fully involved in the dance, it was as if Ianto only had eyes for Jack. The room and the crowd and the mission and the world seemed to fall away for a few long moments.

That haunting voice coming over the speakers and the blue eyes across the dance floor were all that were left in Jack's awareness.

A falling star fell from your heart

And landed in my eyes

I screamed aloud, as it tore through them

And now it's left me blind

Thankfully a large and uncoordinated bar patron fell against Jack heavily, apologizing sloppily. It broke the spell that had frozen Jack in place and had distanced Ianto from fully participating in the challenge at hand. Jack knew what would work now to get his team up near the device. He quickly typed the message into his wrist strap.

I: Jeremy is the key and he is making his decision based on the men. It's up to you. Pull out all the stops. I know you can do this.

Jack saw the momentary self-doubt flash across his lover's face. But then he saw him squint in concentration. Ianto glanced back at Jack and let his eyes sweep over his captain from head to toe and back again. He then gave his a swift nod and leaned in to whisper something to his dance partner.

Out in the parked SUV, Owen was moaning in annoyance whilst yelling at the computer screen. "When are Jack and Ianto going to quit eye-fucking one another long enough for Ianto to get one with getting in there then?! We should have never let him go in there. Bloody Harkness!"

As if in response to the unheard complaints of the doctor, Ianto and Toshiko took their dance right up to the front of the VIP section. They took full advantage of the driving beat of the song. Ianto made sure that at the completion of every turn he was left facing the Brookfields. He captured and held Jeremy's gaze with a fierceness. There was no confusion or ambiguousness left in the heat of that look. To her credit, Toshiko also kicked her seductiveness up about 10 notches. She batted her long lashes and licked her parted, panting red lips. She let her lips graze down Ianto's jaw line slowly.

Within seconds the Brookfields abandoned their champaign flutes and started to descend the three stairs to the dance floor. Jeremy took his wife in his arms and they began to turn and twist among the two couples there. The Brookfields moved with a sexual fluidity that allowed them to weave close to each couple so that it was almost difficult to tell who was dancing with who at times. The tall couple broke apart and briefly paired off the the Brookfields, Jeremy then spinning the leggy shimmering woman as Elena was happily plastered up against the abs and chest of fair-haired adonis. When they met up again Elena giggled in her husband's ear, clearly pleased with that possibility for the evening. But she looked to him for his opinion, just as Jack had surmised.

Jeremy deftly spun them over to Ianto and Tosh as the music was reaching a dramatic crescendo. But as the Brookfields attempted the same partner trading maneuver again, Ianto had anticipated it. With a few quick subtle extra steps, Ianto guided the hand he took from Mrs. Brookfield into the awaiting delicate gloved grip of Toshiko. He then turned and masterfully, firmly, swept Jeremy into his embrace. Jeremy's eyes flashed, his breath faltered momentarily, and he was allowing Ianto to lead before it even registered in his suddenly lust-addled brain that his feet were moving.

Ianto held him so dangerously close that the two men were practically sharing the same breath. Jeremy's pupils were blown so wide that his irises were barely visible. But as focused they were on one another's eyes, their feet moved in a mesmerizing series of steps that were reminiscent of a tango. Jeremy's eyes shifted to the full, soft lips of his mysterious dance partner and he started to lean in. But just then he was spun out away from Ianto. When the two came back together Ianto gave a cheeky wink and smile that made Jeremy giggle much like his wife had moments before.

Speaking of Mrs. Brookfield, she was currently wrapped along the back of Toshiko, Elena's chest pressed against Tosh's bare shoulder blades. Elena's hands were on Tosh's hip bones as Tosh in turn had her arms raised up and behind her, tangled in Elena's loose curls. They two women's faces were turned toward one another over Tosh's shoulder, small wicked smiles on both sets of lips. Their bodies rocked in unison as one feminine fluid wave.

"Jesus" uttered Owen Harper.

"What was that Owen?" asked Gwen innocently.

"N-nothing." he barely stammered in response.

At the conclusion of the song the two couples rejoined their original pairings, but not before Jeremy Brookfield whispered an invitation into Ianto's ear. He replied with a warm smile, took Tosh's hand, and followed the Brookfields into the VIP section.

The screens from the contact lens feeds went blank in front of Gwen and Owen just as they lost visual on them on the CCTV feed as well. The two disappeared into the gray distorted portion of the the picture, obscured by the more-advanced jamming tech in place in that section of the club.

"Let's roll!" announced Owen, gathering himself to his professional responsibilities again. A few moments later, they were in the club.
