Steve reeled slightly, pulling back in surprise, but then he saw Bucky grinning as he ducked into the tent, and that eased enough of his confusion for him to momentarily let his circuits fry and enjoy this. He kissed her back, letting her lead, still unclear as to her motivations but certainly not complaining.

Kat stopped as Bucky walked in, but didn't look back at him, just at Steve. "Well, I liked that. Did you?" She asked, a little breathlessly, her cheeks pink, a few strands of red hair loose in her eyes.

He glanced at Bucky, confused, but then looked back to Kat. "I did like it... Yes. It was great, really, but... Ah... Why...?"

Kat sat down on the cot next to him with a huff of a laugh, shaking her head and running a hand over her hair. "Ask Barnes that one. His idea. But," she shrugged, still smiling and flushed pink. "I think he got what he was hoping for from it." She said, then looking over at Bucky and holding out a hand to beckon him over, her eyes flicking down to his lips.

He turned to make sure the tent flap was tied tightly shut, before walking over to them. "It occurred to me that I like sharing," he said calmly. Steve turned red.

Kat was already red, but the situation wasn't getting any better. "So-" she started, her voice a little squeaky, and she cleared her throat into her fist before trying again. "So how... Does something like this work? Assuming that we're all agreeing to.. to.." She broke off with a slight, embarrassed laugh. "Sorry, I'm a nurse, I should be-"

Steve's hand came up to squeeze her shoulder, and she met his eyes with as much composure as she could in this situation that was quickly becoming unreal to her. "I think we're all... in agreement, yeah." Steve said, adam's apple bobbing as he swallowed, looking at Bucky for confirmation and finding it in his steadiness. "But I'm not sure myself. So far, everything seems to go smoother when we're all communicating. Keeps us on the same page."

"Yes," Bucky said with a calm nod, smiling at the other two. "It's easy. We just do what we were doing anyway, but together. And you and Steve get a chance to say hello."

Kat snorted at his confidence, but she looked at Steve and thought Might as well give it a shot, right? And leaned over to kiss him again, her heart jumping in her chest.

Steve was not all that practiced kissing girls. Once or twice, sure, after the serum and the USO shows had made him famous, a girl had brought him home. He wasn't completely amateur. He wasn't an expert, though, either. One incredibly enthusiastic girl calling all the shots and a different, mid-deserted occasion did not an expert make. He knew how to kiss, how to touch, but it was mostly how to kiss and touch Bucky, with all his sharp edges and rough motions. His first thought, as he lifted his hand to cup her jawline, was just... soft. God, he marveled over how soft women were, and Kat was no exception. Her lips, her skin - he was betting her hair, too. He didn't reach for it quite yet, letting her (or Bucky, if he stepped in soon) set the pace.

Bucky hung back for a while, just watching, before he walked forward to brush fingers through Steve's hair, and bent to kiss the back of Kat's neck.

Kat and Steve both shivered as Bucky made contact. Kat kissed Steve a few moments longer, then nipped his lower lip to let him know she was leaving but she'd be back, and pulled away enough to turn and hook her fingers into Bucky's collar, where she encouraged him to come close enough to give the treatment she'd just given to Steve to him. Steve, ever the tactician, looked ahead a few steps and got up to grab the extra blanket from the foot of the cot, unfurling it with a snap of fabric and giving them a more comfortable place to all sit on the floor. Then he returned to the spot he'd be in, hands reaching out to touch them, to slide over waists, fingers pressing softly.

Bucky caught Steve sitting out of the corner of his eye, and pushed Kat back into his lap with a smile, watching with a laugh as both of them startled slightly.

Kat gave Bucky an accidental kick to the shin out of surprise that she doubted he felt as he slid her backwards, Steve's hands catching her waist, seemingly out of reflex. But she had to admit that she very much did enjoy them there. She thought about protesting being pushed around like a doll, but as Steve adjusted her (effortlessly? Was that effortlessly? ) into a more comfortable place, she decided that maybe she liked it. Still, Bucky was being much smoother than she thought even he could be, and she squinted suspiciously. "Why do I feel like you've done this before? Steve and I are scared out of our wits-" here she elbowed Steve a little to get in on it, very obviously, "And you look like you're well in practice. Share your expertise, why don't ya!"

"He's got plenty of experience," Steve snorted. "He ever tell you about Stark's science expo? He had a girl on each arm and that was not the first time."

Bucky laughed, but didn't argue. "Listen, twink. Just because you lived like a nun doesn't mean we all had to." He glanced at Kat with sudden sheepishness. "But it wasn't nearly as bad as he makes it sound."

She kicked him again, though gently, and rolled her big green eyes. "Oh, hush. I'm a nurse, not a nun like Steve," she retorted, a smirk pulling at the corner of her lips, and a squeeze of her hand on his upper thigh where she was bracing herself, "I've seen more men naked in one damn day in the 107th than I bet you ever saw of girls in Brooklyn. Heard all their foolish lines and the stories they tell one another. I always thought it might be a good time - but you boys..." she shook her head a little, and the pink was back in her cheeks. She chuckled. "You guys are somethin'." They were unbelievably handsome, is what she meant, but while unafraid of the human body, she was a red-blooded woman. They were overwhelming in how much she liked them.

"Hear that, Rogers?" Bucky asked with a smile, leaning forward to snog Kat properly, pushing her back against Steve's chest. He pulled back enough to say, "We're something," with a cocky grin, before he was reaching around Kat to grab Steve's ass.

Kat made a soft sound at his kiss, the hand that wasn't bracing herself raising to tangle in his shirt collar. Steve's fingers were firm against her waist. "Yeah, I heard her," Steve said with a tone that told her he was smirking, and his fingers squeezed as Bucky reached past her. She could take a guess as to what happened. Taking a little initiative, she slid back further in Steve's lap - he groaned quietly, enough that she could feel it where his chest pressed against her back.

Bucky was having the time of his life, and- for once- not thinking. He was caught up in the way Kat and Steve smelled when they were this close together- The faint scent of the oil Kat put in her hair to keep it manageable, combined with the pine tar soap that was Steve's one deviation from standard army issue toiletries. The faint smell of leather and wool and both of their bodies that he knew so well, now combining like the scents of some multi-course meal just waiting to be enjoyed.

Steve was still holding back slightly, but he could tell it was nerves, not discomfort, so he just kept egging the other man on with small touches which he kissed Kat hungrily.

Steve dropped his head to kiss up the side of Kat's neck, hands sliding down her waist to her hips, gaining a little more confidence when she pushed back into him again and pulling her against him a little firmer, pressing his hips up a little. Kat made another soft sound into Bucky's lips, the hand braced on Steve's thigh squeezing while she nipped Bucky's lower lip with her teeth. Her heart was beating harder, and her skin felt hot where she had been cold only a while earlier.

Bucky started working to undo Kat's layers, untucking her blouse from her trousers and searching for skin the winter kept tucked tightly away.

She pulled insistently at his shirt in response, Steve helping Bucky with dragging her blouse out of her waistband, his hands hot on her skin. "This is really working for me, gotta say, fellas," she chuckled breathlessly.

"I thought it might," Bucky said with a laugh. "Neither of you are subtle ogglers." He sat back enough to pull Kat's shirt over her head, grinning, as he tossed it aside.

Kat scoffed at the same time Steve made a choked noise, then laughed, Kat turning a little to look at him. "Well I didn't notice! You were ogling me?" She asked through half a laugh, disbelieving.

"Jesus Christ ," Bucky muttered under his breath, unbuttoning his shirt as Steve flushed an even deeper shade of red.

"I- I mean. Sometimes."

Kat shook her head and laughed, shifting her position enough to be able to reach Steve's shirt buttons, undoing the first one with pink cheeks and a smirk. "Good, I feel like less of a lecher myself," she chuckled, glancing back at Bucky just to get another eyeful of him undressing before she leaned up to kiss Steve again, her hands still getting Steve out of his shirt.

"You two idiots would be lost without me," Bucky muttered fondly as he watched Steve wriggle out of his shirt and reached out to trace a finger down Kat's spine.

"You're probably right," she chuckled against Steve's lips. He flipped off Bucky behind Kat's back, too busy enjoying kissing her to bother speaking, finally getting out of his shirt and smoothing his hands up Kat's back.

"I'm getting there, Steve. A little patience," he said with a laugh as he moved back, pressing his bare chest up against Kat's back and Steve's arm with a pleased hum.

Kat was going to ask what she'd missed, but then she was engulfed on both sides by firm, hot (literally, hot - as cold as it was she was no longer feeling anything but warm) man, and she shivered palpably. She reached back with one hand to hook two fingers into Bucky's trousers, her other hand doing the same, but in Steve's. She wanted to make it clear how far she intended to go.

Steve felt his hips twitch as Kat's fingers brushed his skin, and he stifled a groan. The arm trapped between Kat and Bucky he shifted, so his hand was dragging lightly down her back and his chest.

Bucky rolled his hips forward against Kat's grip, eager acceptance and excitement. He pressed her further against Steve, and bent his head, pinning her in place as his tongue traced the outline of her brassiere.

She gasped against Steve's lips as she felt Bucky's tongue on her skin, and suddenly she was a few more rungs into Impatient, and she did her best to undo both of their trouser buttons at the same time, one-handed. Steve brought a hand back from its travels of Kat's body to help, and when his pants were unbuttoned she twisted in Steve's lap to attack Bucky's buttons while Steve dropped his lips to her shoulder, kissing a line up the side of her neck.

Bucky helped her undo the fastenings, reaching out to find the buttons of her dance skirt and loosening it. Steve took over once he had, pushing the skirt down over Kat's hips, his shyness forgotten.

She shivered as they worked together to undress her, her hands finding both of them once again, sliding down over the rock hard bulges in their underwear, bold and unapologetic. She didn't care about appearances anymore - Bucky had gotten rid of most of that, and right now nothing like decorum was held in her brain.

Bucky was getting very tired of the whole 'touch a little bit' game, and gave up on it altogether. Pulling Kat's skirt all the way off, he pushed her and Steve down to the ground with an effortlessness that would have bothered him had he thought about it. As it was, he wasn't thinking. He just pushed them down and put his tongue to work on anything exposed.

"Fuck," Kat gasped, and Steve laughed, scraping his teeth across her the side of her neck, his inhibitions melting away with every passing instant. " Bucky."

"I'm trying!" he laughed. "The two of you are so bloody impatient."

Steve hauled Kat back against his chest, his arms locking over hers lightly as he pulled her shoulders back while Bucky went after the fastening of her brassier.

"Bucky, I swear-" Kat half said seriously, half-laughed, then made a small squeak as Steve surrounded her, and helped shimmy out of her bra as Bucky released her from it.

The two men worked in efficient tandem to finish undressing her, before Bucky sat back to rid himself of his boxers. He turned to glance at the tent flap, and moved over to be doubly sure it couldn't be opened from the outside.

Steve watched him move with a rising hunger. It had been a long time since they'd dared this. Since they'd had a chance to do anything- and now with the addition of Kat... The allure of the forbidden sent his pulse racing.

Kat ignored Bucky's leaving for the moment - he was vigilant about privacy, which she heavily appreciated - and busied herself exploring Steve, finding him just as pleasing to touch and look at as Bucky was. She ground down on Steve through his underwear, nipping the corner of his jaw, then tapped her finger against his side once, to get his attention. "You got any condoms in here, soldier?"

"Ah... Yeah... I should..." He said, distracted, turning to look around with an attempt at concentration.

"Last USO package had a few," Bucky said with a grin, turning back. "I know for a fact you haven't touched them."

"You've been going through my mail?" Steve laughed, sitting up and with a casualness born mostly of his blood being drained from his brain, just picked up Kat and carried her one-handed to his bag in the corner, opening the letters pouch and rifling through it as she clung to him, laughing softly in his ear. She'd squeaked a little as he'd picked her up, but otherwise her face was bright red and highly amused.

"No, it's the same package we all got, idiot," Bucky said fondly, walking back over and kneeling in front of Kat again.

"Hey, you," she giggled, from her spot on Steve's hip, and he set her down right where they were. She shifted over on her knees to grab Bucky's chin and coax him in for another deep kiss, leaning into him in the nude, and Steve was distracted from whatever comeback he had been preparing for Bucky by an eyeful of Kat's round ass.

"Kat..." Bucky sighed, pulling her closer, his hand slipping between her legs. He wanted her, and Steve, but he surprised himself that more than that he wanted to watch the two together. Wanted to see them each enjoy the other in the ways that he enjoyed them.

She let out a soft whimper, fingers tightening almost imperceptibly on his chin at his hand between her legs, need beginning to rise in her chest. Steve snapped out of his momentary pause and took the final step over to kneel behind Kat, his hand sliding over her hip.

"Suit up, Captain," Bucky said playfully, eyes finding Steve's blue ones. "Don't want to leave her waiting."

Kat chuckled, twisting to look at Steve over her shoulder, just a hint of shyness to her gaze. Steve could feel a similar feeling in his own chest, but the lust muted it enough for him to get out of his underthings and roll one of the condoms on, tossing the other Bucky's way. "I do want to say that you've ruined that for me, now," Steve said to him, to push through his nerves, though his sky blue eyes were on Kat. "Dugan is going to tell me to suit up for a mission and all I'll be able to think about is... This," he chuckled. Kat grinned.

"Good. Now come a little closer and really give us all something to think about later, hm?"

"I feel like 'ruined' is the wrong word, there," Bucky laughs.

Steve leaned forward a little more, an arm wrapping around Kat and pulling her back against his bare chest. Bucky smiled, leaning back enough to admire as Steve ground his hips forward slowly against Kat's ass. "You want this?" the blond asked quietly. "You're sure?"

She took in a deep breath, one hand wrapping around his massive forearm where he held her, the other slipping into Bucky's hand, and she nodded. "I'm sure," she whispered - her anticipation sapping the strength from her voice, but she was confident that they could hear her words, if not the swift beats of her heart. She ground back against Steve as proof, fingers squeezing his arm.

He nodded, his own breath caught in his chest as he took her hint. She was hot and slick, and he let out a stifled moan as he adjusted and then pushed into her from behind.

She moaned with him, her head falling back against his big shoulder, both her hands tightening on their respective grips, and circled her hips slightly, unable to keep still. " Fuck ," she breathed.

Steve muttered a few very un-american phrases under his breath, pulling Kat against him and leaving her just enough room to move with him as he rolled his hips slowly. "Fucking hell Kat..."

She let out a breathless laugh, managing, "You could say that again," and then made a ragged noise, her left hand tight on his arm, the other pulling at Bucky's hand, trying to get him to come closer. She wanted to get engulfed.

Bucky didn't object, leaning forward to kiss the taut band of muscle along Steve's throat as his lovers enjoyed each other. "Take it slow, Kat," he said playfully. "The man melts for a good tease."

Kat nipped Bucky's shoulder and dropped his hand to wrap her fingers around his cock instead, following his advice and keeping her rhythm with Steve slow for the moment. Talking was not high on her list of priorities at the moment. Nor, honestly, was thinking. Steve, meanwhile, was already melting, with Bucky going after the sensitive spots on his neck and Kat rolling her hips back into his so deliciously well. He increased the power of his thrusts a little without really meaning to - Kat groaning low in response - and dropped his head further to kiss Kat's throat, starting just below her ear and working his way down.

"Fuck, Kat," Bucky breathed as he pressed his hips foward against her grip. He was rock hard just from watching the two other people in the tent interact, and her touch was running through him like electricity.

"That's what I'm doing," Steve laughed, though his voice sounded pretty close to wrecked. Kat laughed too, though much more breathlessly, her hand stroking Bucky as regularly as she could manage while being fairly distracted/consumed with Steve's cock doing such good things to her.

"And... A good job, too, Rogers... by the sound of it," Bucky retorted. He bent to kiss Kat, any sense of coyness out the window, all teeth and hunger and eagerness. He knew her taste- it was familiar by now- but kissing her while she was breathlessly riding Steve was a new experience that he thrilled in.

She made a noise of enthused agreement and kissed him back with enthusiasm if not much delicacy, teeth clashing with his, her fingers tightening their grip on him a little. Steve, getting a good eyeful of Kat and Bucky making out for the first time in the midst of sex, felt a shudder go through his body. He'd heard them every time she'd spent the night in Bucky's tent - not on purpose, but there was little to do about his hearing - but imagination (what he couldn't repress, anyway, on those lonely nights) had not done the art of the two kissing justice. God, he couldn't fathom the two of them fucking. He scraped his teeth across her shoulder as gently as he could manage while the fire of those nights of accidental eavesdropping building up his spine brought a new force to his movements - he just tried to keep in mind that he was strong enough to bruise her with an errant touch, let alone the energy he was currently filled to the brim with.

Bucky couldn't help rolling his hips into her grip, his desire for friction rolling along his spine like a tidal wave. He reached past Kat, got a hold of Steve's ass again, sandwiching Kat more or less between them and indirectly pushing her more firmly onto Steve's cock.

"Fuck," she gasped, Steve groaning behind her, the sound vibrating through her chest. Kat's strokes on Bucky were rough, distracted but still into it.

Bucky pulled away from her before she took him over the edge too soon, moving off to the side for a moment to admire the two of them together.

When he moved too far away her hand dropped, grabbing onto Steve's arm around her waist briefly, like her other hand was doing, but then she lifted it back and slid it into the back of Steve's hair, fingers fisting in the blond strands. Her back was arched a little, keeping Steve at an angle she was very much appreciating, and her head was pressed back a little into his huge shoulder - Steve could see that her cheeks and neck were both flushed red. He wondered, as he pulled - no, grappled was closer to his fervor - her closer to him, if she could feel his thundering heartbeat. He could hear hers if they paused to let him listen, he was sure, but where was the fun in that? Kat writhed against him a little more desperately, and his attention snapped back.

Bucky slid forward again to re-enter the fray, arms engulfing the other two, fingers intruding in just the right places to keep things interesting. He took the cussing as a compliment, and for the first time in a long time he was completely, unreservedly, happy.

He wished he could say it wasn't an isolated incident- that that night marked a change in all of their lives, that the three of them shared a tent more often than not, snuck nights together, forged a secret romance. But of course that wasn't a possibility. Not here, in the slowly-thawing forests, with tents slowly sinking into mud and nothing but thin canvas between them and their fellow soldiers.

There were a few more nights on the town, but nowhere large enough to entice the whole camp, and opportunities were few and far between. One scouting mission, just the three of them, but that was into enemy territory and none of them were quite that stupid. A few furtive, quiet, stolen nights, a lot of kissing while playing cards, but all in all... Life went on.

Steve would never admit it, but he was relieved when Colonel Phillips officially sent word to him that it was time to report for leave. Sure, he'd probably have to put in a few appearances for propaganda filming, but the thought of a week and a half of sleeping with both eyes shut overrode all others. Even ones that questioned what he would do or say if Peggy made an appearance. The last they'd seen each other had been left on an awkward footing - that blonde agent had seen to that with her kiss behind the bookshelf. And now, with what had happened, (was happening? Their flirtatious card games seemed to indicate that it hadn't been a one-time thing.) he was left with doubts.

He gave the word at breakfast that morning, to several loud cheers, and they moved out that afternoon.

A/N

Sorry to anybody disappointed by the cutoff in the smut! We decided that we'd written a good chunk of it and then ran out of steam somewhat, and there's nothing worse than half-assed smut, am I right? We're definitely better off this way!

Will be 2 more Glimpses after this chapter today!
