Where the Wild Things Idle

Summary:

Tony Stark has learned how to survive by staying small, brilliant, and untouchable.

An omega in a world that tolerates but does not indulge, he hides his instincts beneath intellect and sharp edges, suppressing needs he has never been allowed to explore. When a stolen afternoon with Rhodey leads him into a Brooklyn garage, Tony is unprepared for the alpha waiting there.

Bucky Barnes is not looking for trouble. But it has found him. The omega knelt on the floor, hands black with grease, curls loose around his face. His eyes were wide with excitement, brown and bright, fixed on Bucky like he had just been handed something precious. His mouth was slightly open, lips full and soft, caught between awe and breath.

This was trouble.

And it was exactly the kind he had been waiting for without ever knowing it.

Chapter Text

Tony moved quickly through the crowded New York streets, slipping between bodies with the ease of someone who had learned young how to make himself small when necessary. His white designer sunglasses were pushed haphazardly into his hair, barely managing to keep his curls out of his eyes. They slid forward every few steps. He ignored them.

The sunflower-yellow sweatshirt hung loose on his frame, sleeves too long, cuffs frayed soft with wear. The fabric brushed against his wrists when he walked, hiding how slender they were, how easily a firm grip could span them. The graphic across his chest, Advice from a Sunflower, was cracked and faded, stubbornly surviving wash after wash. He liked it that way. It felt lived in.

His jeans were pale and patched, reinforced at the knees, cuffs rolled unevenly. Yellow socks peeked out above scuffed Converse, the canvas creased and dulled. The outfit would never pass inspection. Not in that house. Not under Howard Stark’s eye. Tony caught his reflection in a passing window and lingered just long enough to register the familiar sense of relief. This, at least, was his.

If his father saw him dressed like this, there would be consequences. Tony did not dwell on the specifics. He had learned the value of forward momentum.

The Starbucks came into view and he slipped inside just as the bell chimed. Warm air wrapped around him, thick with the smell of coffee and sugar. His breath was faintly unsteady, excitement still humming under his skin, the quiet satisfaction of having gotten away with something. It never really went away.

He ordered on autopilot. Paid without glancing at the screen. When his drink was handed over, he took it carefully, fingers brushing the cardboard sleeve. The heat barely registered in his callused fingertips, skin long accustomed to soldering irons and overheated components. He lifted the cup, took a sip too quickly, and bit down on his lower lip as the heat burned his tongue. He swallowed it anyway, eyes briefly closing.

He chose a table near the window, back to the wall, chair angled just enough to give him a clear view of the room. He perched rather than sat, one leg tucked beneath him, shoulders drawn slightly inward. His sleeves slipped down over his hands again and he did not correct them. He cupped the mug between his palms, warmth seeping in slowly.

Too early, he thought, checking his phone. Of course he was early.

His foot bounced beneath the table. When he caught himself gnawing lightly at his lip again, he forced his jaw to relax and took another careful sip. Outside, people passed in a blur of coats and movement. Inside, time felt suspended, delicate.

The bell chimed.

Tony looked up.

James Rhodes stood just inside the doorway, scanning the room with an ease that bordered on instinct. He looked older than Tony remembered, broader, more solid, the bearing of the military clinging to him even out of uniform. When his eyes found Tony, his mouth curved into a familiar smile.

“There you are,” Rhodey said, already moving toward him.

Tony felt something settle in his chest. “You’re late,” he replied, tone mild, practiced.

Rhodey dropped into the chair opposite him and leaned back, stretching his legs out. “You’re early. As usual.”

Tony huffed softly and took another sip of his coffee, this time careful. “Habit.”

“Howard behaving?” Rhodey asked, voice low enough not to carry.

Tony shrugged, one shoulder lifting beneath the oversized fabric. “Define behaving.”

Rhodey studied him for a moment longer than necessary, gaze flicking briefly to the shadows under Tony’s eyes, the way his hands stayed hidden. He did not push. He never did. “I’m off for a few days,” he said instead. “Figured I’d steal you while I could.”

Tony’s mouth curved, small and genuine. “You say that like I’m hard to kidnap.”

“Please,” Rhodey said. “You’d escape before we hit the corner.”

They talked easily, the way they always had. Rhodey filled the space with stories about base life, about bureaucracy and people who took themselves too seriously. Tony listened, interjecting occasionally, dry remarks timed just right. When Rhodey mentioned his father’s old Harley, still sitting untouched, Tony leaned forward without realizing it.

“You kept it,” he said.

“Yeah,” Rhodey replied. “Couldn’t let it go. Thought I’d get it priced. There’s a garage nearby. Old place.”

Tony hesitated. He glanced toward the window, toward the street, toward the direction that led back home. Then he stood, already tugging his sleeves down again. “I’ll come.”

Rhodey raised an eyebrow. “You sure?”

Tony nodded. “I am.”

They stepped back outside together, Rhodey’s presence steady at his side. Tony matched his stride, close enough that their shoulders nearly brushed. The city pressed in around them, loud and bright, but he felt insulated, briefly, by the simple fact of not being alone.

The garage announced itself before Tony consciously registered the building. It was the smell that caught him first.

Cold and clean and sharp. Pine and metal and something darker beneath it. Like a winter morning deep in a forest, fog clinging low to the ground, the air so crisp it burned going in. Wild freshness edged with danger, the kind that made instinct stir before thought had time to interfere.

Tony slowed.

He drew in a deeper breath before he could stop himself, chest expanding, pulse shifting. The scent wrapped around him, settled somewhere low and unsettlingly familiar. His fingers curled inside his sleeves.

Rhodey kept walking, oblivious, already lifting a hand in greeting. Tony followed a step behind and then another, eyes tracking the source.

An alpha.

There was no mistaking it. The man stood behind a workbench near the center of the garage, broad shoulders filling out a sleeveless leather vest worn soft with age. Dark brown hair was pulled back into a rough bun at the nape of his neck, a few loose strands escaping to brush against his jaw. Both arms were inked from shoulder to wrist, bold lines and heavy shading disappearing beneath grease-streaked skin. The tattoos were real, worn in, not decorative. They moved when he did.

His hands were filthy, oil ground into the lines of his palms and beneath his nails. A cigarette rested between his lips, unlit but familiar, like it belonged there. When he looked up, his eyes were a piercing, startling blue.

They flicked to Rhodey first.

Then to Tony.

One eyebrow lifted, slow and questioning, as if he were trying to place him. As if he were wondering what, exactly, this boy in yellow and denim was doing in his space.

Tony’s first instinct was to step back.

He shifted slightly behind Rhodey’s shoulder, body angling inward, pulse jumping sharp and fast. The scent pressed in closer now, stronger. His mouth went dry.

Get a grip.

He straightened, lifted his chin, and let the familiar armor slide back into place.

“Is that a four stroke,” Tony said, voice sharp and cool as he stepped around Rhodey, “or are you still pretending two stroke engines haven’t been obsolete for decades.”

The alpha blinked.

Tony continued without waiting for an answer, already scanning the engine on the workbench, eyes narrowing. “Rear wheel drive, chain transmission. Six speed gearbox, maybe seven if you are compensating for poor torque distribution. Judging by the wear pattern, you swapped the carburetor without recalibrating the intake.”

He leaned closer, peering down. Too close, really. “Which is sloppy. You are losing efficiency. A belt drive would have been cleaner.”

Behind him, Rhodey pressed his lips together, amused.

Across the bench, Bucky Barnes straightened slowly, cigarette forgotten between his fingers. The kid was sharp tongued, clearly, but that was not what caught him. It was the way his eyes moved. Focused. Precise. Hungry in a way that had nothing to do with appetite.

Bucky opened his mouth, prepared to snap back.

Then Tony drifted another step closer without realizing it.

From the corner of his eye, he caught sight of something half hidden beneath a heavy canvas cover near the far wall. His breath caught. The sharpness in his voice faltered, replaced by something raw and unguarded.

“Wait,” he said, already moving. “Is that a Vincent.”

Bucky frowned. “What.”

Tony was halfway across the garage before the word landed. He yanked the cover back with both hands.

Black metal gleamed beneath it.

“Oh,” Tony breathed.

The bravado evaporated. He dropped to his knees on the concrete without hesitation, jeans soaking up oil and dust, hands already reaching out. He touched the engine reverently, fingers skimming over the blacked out casing.

“This is a forty eight Black Shadow,” he said, voice softer now, reverent. “Nine hundred ninety eight cc V twin. Fifty five horsepower. It could hit one hundred and twenty five miles per hour when most bikes were barely scraping ninety.”

He laughed quietly, breathless. “Do you have any idea how ridiculous that was for its time.”

Bucky stared.

Tony leaned closer, curls falling into his eyes, completely unconcerned. “Minimalistic design, blacked out engine to reduce glare, clean lines. People thought it was dangerous. They were right. That was the point.”

He glanced up then, eyes wide and bright, cheeks faintly flushed. “They go for hundreds of thousands now. Depending on provenance.”

He turned fully toward Bucky, still kneeling, hands black with grease, mouth parted in awe. “Where did you find this.”

Something in Bucky’s chest shifted.

Fuck.

Bucky caught himself staring.

The omega was still kneeling on the floor, hands black with grease, curls fallen loose around his face. His eyes were wide with excitement, brown and bright, fixed on Bucky like he had just been handed something precious. His mouth was slightly open, lips full and soft, caught in the moment before restraint returned.

It hit Bucky harder than it should have.

Beauty like that was dangerous. Breath catching. Heady when directed at someone with such pure, unguarded delight. Dangerous in the way it drew you in, especially when paired with intelligence and passion, when it lit someone from the inside out and dared the world to keep pace.

Bucky forced himself to breathe.

“It was my old man’s,” he said. His voice came out rough, scraped raw around the edges. He cleared his throat and tried again. “I’ve been meaning to fix it up. Never seemed like the right time.”

The omega blinked at him, baffled.

“Never the right time,” Tony echoed, incredulous. “For a treasure like this, you make the time.”

Something warm and unexpected stirred in Bucky’s chest. He could not help the smirk that curved his mouth, slow and indulgent.

“Well, doll,” he said, tone dipping before he could stop himself, “seeing as you’re a treasure yourself, I suppose I’ll have to bow to your superior knowledge on the matter.”

Three things happened at once.

First, Bucky shook himself slightly, unsettled by his own words. He was not one to flirt lightly, not over wide eyes and unfiltered awe, no matter how intoxicating they were.

Second, a pointed cough sounded from behind him, reminding him sharply of the other alpha still standing near the entrance of the garage, forgotten until now.

And third, most importantly, a blush bloomed across the omega’s cheeks, rich and unmistakable. Surprise crossed his face, eyes going momentarily wide, lips parting again as if he did not quite know what to do with the compliment.

Bucky’s breath caught.

Surely someone who looked like that was used to admiration by now. Surely he had heard worse, heard better.

Bucky straightened, hands flexing unconsciously at his sides, grounding himself. This was not the time. Not the place.

Still, even with the weight of the other alpha’s gaze pressing between his shoulder blades, his eyes lingered, reluctant to let go. The kid was trouble. That much was clear.

Not just because of his beauty. Or his intelligence. But because Bucky could not catch even the faintest hint of his scent. The omega was young, excited, clearly engaged, and yet locked down so tightly it bordered on unnatural.

A mystery.

And Bucky knew himself well enough to recognize the pull of one.

As he finally tore his gaze away, he thought, with a quiet certainty that settled deep in his bones, that this might be exactly the kind of trouble he had been waiting for without ever realizing it.
