Reunion

Summary:

Stanley and Xeno finally get a moment alone!

Notes:

My first try at smut, this took multiple weeks to write bc I couldn't write it in daylight and was EMBARRASSED. (I'm asexual). My notes app refused to correct the text bc it contains smut, there may be grammar errors bc of that.
Hope you enjoy anyways:)

(See the end of the work for more notes.)

Work Text:

The command tent buzzed with voices, equipment, and the smell of hot solder. Chrome was bent over a table of transistors, muttering counts under his breath; Ryusui barked flight-check orders at anyone who looked idle. Even Kohaku, normally patient, looked close to snapping as she hauled a crate of quartz tubing.

 

Xeno stood near the launch scaffolding, clipboard in hand, eyes sharp behind smudged lenses. “Fuel mix check, stage two,” he called, not looking up. “I want that data logged before midnight.”

 

“Already on it!” Gen sang from across the way, flashing a grin that didn’t reach his tired eyes.

 

Stanley leaned against a crate, arms folded, watching the chaos. He’d been awake for only a few days, and already it felt like he’d never been gone. The smells, the jargon, the rhythm of a mission—it all came rushing back. Only one thing felt different: the strange distance between him and the man giving orders a few meters away.

 

Senku jogged past with a bundle of printouts. “Hey, Commander! Trajectory calcs look solid—assuming your boy here doesn’t crash the rocket.”

 

“Stanley doesn’t crash.” Ryusui said without looking up.

 

That earned a rare smile from Stanley, but Xeno’s head barely turned. “Focus, people. Why-Man isn't waiting for our theatrics.”

 

Hours blurred. The camp quieted as the others drifted off to their assigned quarters. Only the mechanical hum of the test pumps and the flicker of floodlights remained.

 

Stanley realized he’d been running diagnostics alone for a while. When he straightened up, Xeno was still at the console, tracing equations on a tablet, lips moving silently.

 

“Everyone else called it a night,” Stanley said, approaching. His voice echoed faintly off the metal walls. “You trying to run the whole launch solo?”

 

Xeno didn’t look up. “Someone has to ensure no detail is overlooked.”

 

“You’ve been ensuring that for sixteen hours straight.”

 

A pause. The stylus stilled. “Old habits,” Xeno murmured, finally meeting his gaze.

 

For a heartbeat, the years between them evaporated. The scientist’s face was thinner, the streaks of gray deeper, but the look in his eyes—the mixture of calculation and something warmer—was achingly familiar.

 

Stanley glanced toward the tents. No movement, no voices. Just the two of them and the low hum of the rocket’s heart.

 

“Guess it’s just us now,” he said quietly.

 

Xeno exhaled, setting the tablet down. “So it seems.”

 

The floodlight flickered once, dimming to a softer glow. The camp felt suddenly too still, the silence heavy with everything they hadn’t said since the moment of revival.

 

Stanley took a slow step closer, the corners of his mouth lifting just slightly. “Been a long time, Doc.”

 

Xeno’s reply came out barely above a whisper. “Far too long.”

 

The machine beside them clicked, signaling the end of another test cycle, but neither of them moved.

 

"Xe," Stanley muttered, but never finishing his words.

 

Xeno glanced up at him fixated on his eyes.

 

"You're right, we should call it a night."

 

With that the two left to Xeno’s quarter, since it’s been only a few days since Stanley was depetrified, both shared a room for the time being.

 

Not a second after closing the door, Xeno pinned the blonde against the door cupping his face with his free hand.

 

They all have been so busy with their mission, Stanley and Xeno had not spent much time alone since his depetrification.

 

"Took you long enough, Xeno." Stan whispered impatiently yet desperately to the scientist. 

 

With that Xeno finally locked their lips in a longing kiss. A kiss after years of being parted. 

 

The blonde reached for the scientist’s tie and grabbed him even closer. They pulled away after a few seconds to grasp air.

 

"My apologies, Stan." Xeno answered into Stanley's ear - his warm breath against his skin causing his heart to beat faster. 

 

Xeno leaves a few kisses on Stanley's neck while gently holding the other man's hips, earning a few suppressed humms and moans.

 

"Don't tease me." The ex military declared, clearly desperate for more.

 

"You're impatient, my dear." Xeno hummed but obliged anyway. 

 

He guided Stanley onto the bed and pressed him against it with slightly more force than before. Pulling into a kiss once again, this time more needy and harder. 

 

Their eyes met after parting, both full of desire and lust.

 

"You're beautiful, Stanley."

 

"Since when are you so sloppy?" He teased, clearly enjoying the praise as the pink blush on his cheeks showed.

 

In response Xeno only smiled, stroking over the others flushed cheeks and kissing him gently once again before his hands worked themselves lower, unzipping the bodysuit and revealing trained muscles underneath. 

 

The white haired grinned and tossed his now removed gloves on the ground, letting his bare hands guide over Stanley's exposed upper body.

 

He rubbed over one nipple whilst removing the rest of Stanley's bodysuit, leaving him in boxers.

 

"May I?" Xeno asks, making sure Stanley consents before going any further.

 

Stanley nods and takes the initiative to also remove some of Xeno’s clothes, leaving him with only trousers on. 

 

He feels fingers gently gliding over his entrance which leads to a quiet moan to escape.

 

"Xe.." 

 

Xeno’s face is slightly flushed, his hardened member already visible through his pants, his eyes yearning at Stanley's body.

 

With a gentle motion Xeno pushed one finger inside, looking for Stanley's sweet spot. The only confirmation the man needed to have found it, was the blonde accidentally moaning louder than intended.

 

He continued stimulating the man's prostate until some precum leaked from his dick, signaling he is close.

 

The scientist pulled his finger out again, leaving Stanley feel empty.

 

"You're doing so good. You think you can handle me already?"

 

"I can."

 

Stanley kissed the other man while feeling his parents hardened member against his entrance.

 

With a huff Xeno pushed his dick inside, the first time in 12 years.

 

"Xeno..." Stanley managed to say, some tears forming in his eyes.

 

The man didn't hesitate twice upon hearing his name be called out so desperately and begun pushing and building a rhythm.

 

Stanley's moans began to shake, he barely managed to wrap his legs around Xeno’s waist, letting him feel every thrust hit his sweet spot.

 

"Ah, I won't be able to hold on much longer, my apologies." Xeno said, his usual perfectly secured pommarade now loose, leaving a few strands hanging over his face. His face flushed and his hands holding a tight grib on Stanley's waist.

 

"Me too," Stanley answered with a broken voice, quickly holding his hand to cover his mouth to not let a loud moan escape. 

 

Years of separation and nostalgia left them both close to their orgasm early.

The scientist took the opportunity to passionately kiss the other while his rhythm became more unsteady and desperate to come.

 

Stanley kissed back hungrily, moaning into Xeno’s kiss. With one final thrust directly to his sweet spot, Stanley's thights began to shake slightly, and cum shot from his unattended dick.

 

"Xeno,..." He hummed looking at the others dark eyes. 

 

That's all it took to for Xeno to come inside the blonde.

 

Xeno let himself fall onto Stan from exhaustion, grinning slightly.

"I lasted longer than you."

 

"We're still playing that game?" Stanley teased back.

 

They both showered after a while, deciding to rest. Now again in bed, Xeno wrapped his arms around the other man's belly, holding him on close from behind.

 

"You're truly elegant, Stan."

 

"Yes, yes sure. Go sleep now." He answered annoyed, although his face was clearly hiding a faint smile.
