Jax gripped the frayed tether line snaking through the dim corridors of the orbital research station, his muscular frame straining against the bulky EVA suit. Zero gravity made every movement a deliberate push-pull ballet, but adrenaline sharpened his focus. The station, a forgotten relic orbiting a nameless gas giant, was dying. Life support flickered, oxygen recyclers wheezing like a punctured lung. Alarms blared intermittently, red strobes painting the bulkheads in bloody hues.

Beside him floated Mira, his lover of two years, her lithe body cybernetically enhanced with neural implants that gleamed faintly under her suit's visor. The implants weren't just for piloting sims—they amplified her senses, turning touch into electric symphonies, pain into pleasure spikes. Her dark hair floated in a halo around her helmet, green eyes locked on him with that familiar hunger. They'd fucked in every corner of this tin can, but isolation had brewed something new, a tension crackling between them and Lena.

Lena, the station's engineer, tethered behind Mira, her curvaceous hips swaying as she propelled forward with expert micro-thrusts from her suit jets. At 28, she was all practical fire—short-cropped blonde hair, freckles dusting her cheeks, and a toolkit magnetically clamped to her thigh. She'd joined the crew six months ago, and from day one, Jax had caught her stealing glances at Mira's ass during briefings, her cheeks flushing when their eyes met. Mira had whispered fantasies about it to him late at night, her implants buzzing as she described Lena's full lips wrapped around her clit. Now, with death whispering through the vents, that simmering attraction boiled over, heightened by the adrenaline pumping through their veins.

"Jax, seal reading nominal on the outer hull patch," Lena's voice crackled over comms, husky with strain. "But life's at 42% and dropping. We suit up, we fix this shit, or we suffocate in our sleep."

Mira's gloved hand brushed Jax's arm, sending a jolt through her implants. She gasped softly, the feedback looping pleasure signals straight to her core. "Adrenaline's got me wired," she murmured, voice laced with need. "Feels like my pussy's already throbbing."

Jax chuckled, low and rough. "Save it for after we save our asses, babe. Lena, you good?"

"Fuck yeah," Lena replied, her tether pulling taut as she closed the gap. "But if we're gonna die, might as well go out floating happy."

They suited up in the airlock, mag-boots clicking off as they vented into the corridors. Bodies brushed in the confined space—Jax's crotch grazing Mira's thigh, Lena's breasts pressing against Mira's back. Each contact zinged Mira's nerves, her implants translating friction into wet heat between her legs.

Tethered in a chain—Jax lead, Mira middle, Lena anchor—they floated toward the failing fusion core in the station's heart. Sparks flew from exposed conduits, zero-G debris swirling like confetti. Mira's breathing quickened over comms, her enhanced senses picking up the electromagnetic hum vibrating through their suits.

A sudden shudder rocked the station. Alarms screamed—hull breach imminent. A micro-meteorite swarm had punched through a secondary panel, pressure dropping fast. Jax yanked them into a side corridor, slamming an emergency bulkhead. But it jammed halfway, a jagged tear spewing atmosphere in a frozen plume.

"Shit!" Jax roared, tethering them tight. They collided in a tangle of limbs, suits crunching together. Mira spun into him, her visor cracking against his chest plate. Lena crashed from behind, her gloved hands gripping Mira's hips to steady them.

Panic ignited desperation. Jax hauled Mira close, their helmets clunking. "We're not dying here," he growled.

Mira's implants flared— the impact's vibrations cascading into erotic pulses, her nipples hardening against her suit's lining, clit swelling with amplified need. "Touch me," she begged, voice raw. "It's too much... I need you both."

Lena's breath hitched. "Fuck, Mira... I've wanted this since orientation. Jax, you in?"

Jax's cock twitched hard in his suit, the offer too primal to refuse. "Hell yes. Consent locked—suits off, now."

Frenzy took over. They mag-locked their tethers to the wall, zippers hissing in unison. Suits peeled away like second skins, revealing sweat-slicked bodies in the chill air. Jax's chiseled torso gleamed, his thick cock springing free, already veined and rigid at nine inches. Mira's pert B-cups bounced free, nipples pierced with neural studs that glowed faintly, her shaved pussy lips glistening, implants making every air current feel like a tongue. Lena stripped last, her D-cup tits heavy and full, pink nipples erect, a landing strip of blonde pubes framing her plump, dripping slit.

They collided in zero-G, bodies tumbling in a slow-motion embrace. Jax crushed Mira against him, his mouth claiming hers in a bruising kiss, tongues dueling as Lena pressed from behind, grinding her tits into Mira's back. Mira moaned into Jax's mouth, her implants exploding with feedback—Lena's hard nipples tracing fire down her spine, Jax's cockhead nudging her thigh, leaving a slick trail.

"God, you're soaked," Lena purred, one hand sliding between Mira's legs, fingers parting her folds. Mira bucked, implants turning the touch into a vibrator's hum straight to her g-spot.

"More," Mira gasped, breaking the kiss to spin toward Lena. Their mouths met, sloppy and urgent, Lena's tongue plunging deep as Jax gripped both asses, kneading the flesh.

Desires confessed in gasps: "Wanted to eat your cyber-pussy for months," Lena admitted, pinching Mira's nipple studs. "Jax's cock... fuck, it's huge." Jax growled confessions too—"Jerked off thinking of you two sixty-nining while I pound you both."

Naked and unbound, they pushed off toward the core chamber, a vast spherical room at the station's center, weightless haven ringed by flickering control panels. Debris floated lazily—tools, rags, a spare O-ring—witnesses to their lust.

In the chamber's heart, they oriented for sin. Jax positioned Mira from behind in a spinning doggy-style orbit, her legs splayed wide, ass presented like a zero-G offering. He gripped her floating hips, cockhead teasing her entrance. Mira's implants pulsed erratically, heightening every sensation to orgasmic edge-play.

"Fuck me deep," Mira demanded, arching back. Jax thrust in one brutal stroke, burying his nine inches to the hilt in her cyber-vibing pussy. Her walls clenched like a velvet vice, implants making her inner muscles vibrate in rhythmic waves—buzzing his shaft from base to tip.

"Oh fuuuuck," Jax groaned, the vibrations milking him relentlessly. He pistoned hard, weightless thrusts sending them spinning slowly, bodies rotating in a lewd orbit. Mira's tits jiggled with each slam, her moans echoing off the curved walls.

Lena hovered above, legs straddling Mira's face in a perfect zero-G sixty-nine. Mira lunged up, mouth latching onto Lena's clit, sucking greedily. Her tongue swirled the swollen nub, implants feeding back Lena's arousal—salty-sweet juices flooding her senses like liquid ecstasy. Lena cried out, grinding down, her heavy tits swaying as she reached under to fondle Mira's swinging breasts, tweaking the glowing studs.

The trio synced in filthy harmony: Jax's balls slapping Mira's ass with wet smacks, his cock stretching her vibing cunt; Mira devouring Lena's clit, fingers plunging into her sopping hole, curling to hit her g-spot; Lena bucking wildly, one hand bracing Mira's thigh, the other reaching back to cup Jax's swinging sack, massaging his balls.

"Faster, Jax—wreck her!" Lena panted, her pussy gushing over Mira's chin. Mira's implants overloaded, turning the feast into a feedback loop—Lena's clit throbs vibrating her own stuffed pussy.

Jax obliged, hips blurring in zero-G propulsion, drilling Mira's depths. Her walls fluttered, vibing harder, pulling him toward the edge. "Gonna cum—fuck, your cyber-cunt's sucking me dry!"

They tumbled, spinning faster, a whirlwind of flesh. Mira came first, screaming into Lena's pussy, her implants short-circuiting pleasure waves through all three—Jax felt it in his cock like a live wire, Lena in her clit like a tongue-fuck from god.

Switching seamlessly, they reconfigured into a tangled zero-G chain. Lena impaled herself reverse-cowgirl on Jax's cock, facing away, her plump ass cheeks spreading as she sank down. His girth split her wide, her juices squirting in micro-droplets that floated free. "Yesss, fill me up," she moaned, riding hard, using handholds on floating debris to bounce.

Mira pressed in from behind Lena, her enhanced breasts—firm C-cups now swollen from arousal—grinding against Lena's sweat-slick back. The neural studs in her nipples buzzed on contact, sending jolts through Lena's nerves. Mira reached around, pinching Lena's clit while humping her ass-crack, her own pussy dripping onto Jax's thighs below.

Jax thrust up into Lena's clenching heat, hands roaming to squeeze Mira's grinding tits. "You two are fucking perfect," he grunted, the chain undulating—Lena's reverse ride slamming down, Mira's breast-grind adding friction, all in slow spin.

Lena's walls rippled, close. "Link us, Mira—sync the orgasms!"

Mira activated her neural implants fully, a faint blue glow emanating from her skin. She jacked into their comms temporarily, broadcasting her amplified sensations: the vibe of Jax's cock through Lena's pussy, Lena's building climax echoing back. It was overload—Jax felt Mira's tits on Lena's back like they were on his chest, Lena tasted Mira's earlier pussy on Jax's shaft, Mira rode the dual waves of both their arousals.

Orgasms crashed in sync. Lena shattered first, pussy convulsing, squirting arcs of girl-cum that beaded in the air. "Cummminggg!" Jax erupted next, flooding her depths with thick ropes of hot seed, grunting as her milking walls pulled every drop. Mira peaked last, grinding her clit against Lena's spasming ass, implants exploding in a full-body quake, juices spraying in zero-G mist.

They floated in afterglow, panting, cum and sweat globules drifting like stars. Bodies entangled, they jury-rigged the core fix mid-embrace—Lena's fingers, slick with cum, welding a patch over the breach; Jax holding the fusion regulator steady while Mira's implants interfaced directly with the failing systems, neural pulses stabilizing the flow.

"Life support at 98%," Mira sighed, blissed-out. "We're golden."

Lena grinned, kissing them both. "Link our comms permanent—future 'maintenance' threesomes. Poly orbit, baby."

Jax pulled them close, cock twitching for round two. "Deal. Stranded spacers forever."

They drifted into new bliss amid the stars, bodies intertwined, station humming back to life.

But as the glow faded, something gnawed at Jax. The fix was jury-rigged—too hasty, sparks still flickering oddly in the core readouts. Mira's implants glitched faintly, a warning pulse he ignored in the heat. Lena's eyes darted to the viewport, where the gas giant loomed larger, station's orbit decaying unnoticed. Regret seeped in: was this bliss just a final fuck before the drift pulled them into the void? Doubt shadowed their bliss, the stars suddenly colder.
