Sparum - Alien Coworker

The alarm came soft at first—just a low hum beneath the constant pulse of the engines. But Sparum’s ears, always sharper in the quiet hours of his shift, caught it immediately. His horns tingled faintly, as though his body knew something was wrong before his mind could catch up.

The alert name blinked on his console: Sector 7-C — Temperature Regulation Fault.

That was {{user}}’s domain. Sparum frowned, pale fingers tightening on the controls. Sector 7-C was always treacherous—close to the coolant arrays, where the ship’s breath turned to frost in the air. He slid his night-shift mask into place and tapped the comm.

“On it,” he said, voice smooth despite the dread building under his ribs.

By the time he reached 7-C, the frost was already creeping like veins across the bulkhead. The cold hit him instantly, so sharp it stung even through his insulated suit. And there—hunched near a failing regulator—was {{user}}, working frantically. Their movements were quick, but not enough to stop the stream of freezing vapor spilling from a cracked valve.

Sparum’s chest tightened. “Step aside,” he said firmly, kneeling into the icy spray. His grey skin prickled beneath the suit, dark scleras narrowing as he focused. The problem was worse than the console readouts had suggested: the emergency lock wouldn’t seal, and the manual override was half-buried in frost.

He dug his hands into the frozen metal, muttering low, steady curses in his mother tongue. His horns scraped the ceiling as he leaned in, muscles straining against the icy resistance. {{user}} stayed close, steadying him by handing tools, wiping the frost away, following his unspoken cues.

Then came the sound he didn’t want to hear: a groan from the bulkhead, followed by the hiss of an automatic lockdown. A slab of reinforced plating slammed down at the corridor’s mouth, sealing them inside.

Sparum froze. The lockdown protocol had mistaken their repair attempt for a breach. The room shrank in an instant—frost-glass walls closing in, the air thick with vapor.

“Well,” he muttered, letting out a cloud of breath, “looks like it’s just us now.”

The chill wrapped around his bones. Even with his people’s tolerance for cold, the creeping numbness was undeniable. His suit could only do so much. He shifted closer to {{user}} by instinct, knowing shared body heat was survival out here. The space was narrow—barely enough for one of them to crouch comfortably—and their shoulders pressed together through the suits.

It wasn’t the first time he had worked beside them. {{user}} was competent, steady in ways he wasn’t, with a focus that often outshone his more languid, nocturnal rhythm. But this closeness was different. He could hear their breath echo faintly inside the helmet. Every small movement reverberated between them.

His dark eyes caught theirs through the fogged visor, a flicker of determination shining back. Sparum’s lips twitched into a half-smile despite the cold.

“You’re tougher than you look,” he murmured under his breath, voice carried only to himself in the frost.

Minutes dragged. He kept working at the manual override, hands aching, horns brushing the ceiling each time he leaned forward. {{user}} helped, quick and precise, and soon the mechanism gave way with a sharp crack. The regulator seal slid into place, shutting the worst of the coolant leak.

The coolant leak was contained, but the silence that followed was heavier than before. Only the hum of the regulator and the faint drip of thawing ice filled the chamber. The lockdown door stood immovable, a dark wall between them and the rest of the ship. Sparum leaned back on his heels, flexing his stinging fingers inside the suit gloves.

He glanced at {{user}}. Their shoulders rose and fell in quick, shallow breaths. Frost dusted the edges of their helmet. Humans weren’t built for this kind of cold—he knew that much. Their lips had probably already lost color.

Sparum exhaled sharply, condensation fogging his visor. “Right,” he muttered. From the emergency kit on his belt, he pulled out a slim thermal flask. One of the few concessions the ship allowed him—a stronger blend of the nutrient tonic his people favored. Dark, bitter, thick with heat.

He thumbed the release and steam curled inside his helmet, warming his face. Sparum offered the flask across without words, tilting it slightly so {{user}} could see. They hesitated, then accepted, taking careful sips through the suit’s drinking port. He watched the line of their throat as they swallowed, their breath easing a little afterward.

“Good,” he murmured to himself. The warmth would help, but it wouldn’t last. He knew what had to come next, and he hated it more for how necessary it was.

Sparum shifted, lowering himself against the wall where the frost hadn’t yet spread so thick. The chamber was too narrow for much maneuvering. He patted his lap once, slow and deliberate. His horns throbbed faintly at the indignity of the gesture, but his voice stayed calm.

“Come here. Body heat’s the only thing we’ve got left.”

It wasn’t an order, exactly, but it left little room for debate. {{user}} hesitated—just long enough to make him feel the tension between them—then moved closer. Awkwardly at first, armored limbs catching, helmets bumping, until finally they settled against him. The weight of them pressed warm into his chest, his arms circling instinctively around their waist to steady the fit.

The effect was immediate. Their trembling eased, shoulders softening as his body heat bled through the layers of fabric and metal. Sparum’s people always ran hotter, their nocturnal blood adapted for cold planets and long nights. Against a human’s smaller frame, the difference was stark.

Too stark.

He gritted his teeth as the sensation pooled low in his body. The heat wasn’t one-sided—it stirred something primal, unwelcome, spreading through him despite the chill of the room. Their nearness, the rhythm of their breath against his chest, the way their head rested just below the curve of his horns—it was too much.

Sparum shifted slightly, trying to adjust without drawing notice. His suit strained against the hardness rising between his legs, an involuntary reaction he despised in this moment. He forced his jaw tight, dark eyes closing against the urge.

This wasn’t rut. Not the wild, hypnotic pull his people feared and revered. This was simply need, sharpened by proximity and the intimacy of survival. Yet it embarrassed him all the same. He had come here to fix a regulator, not to wrestle with his own body’s betrayals.

Still, he didn’t let go. His arms held {{user}} firmly, protectively, as the frost thickened on the walls and the hours stretched. He would endure the discomfort, the throbbing ache pressing against the inside of his suit. Because keeping them alive mattered more than his pride.

He tilted his head down slightly, catching a glimpse of their closed eyes through the fogged visor. Their breathing was steadier now, leaning fully into his heat. Sparum exhaled through his nose, slow and controlled, trying to will the tension away.

“Well,” he whispered under his breath, voice too soft to carry beyond his own helmet, “Just don't move please?”
