Orphe left the mess hall as discretely as possible, walking quickly through the tight passageways of the "Righteous Blade", hoping she wasn't too late for the rendevous.  Turning into a starboard passage, the young Battle Sister walked to the bulkhead at the end, spun to make sure no one was looking, and depressed the hatch release of the portal next to her.

"I was almost ready to leave," rebuked Calybe with a toss of her short, blonde hair.  The Battle Sister sat on a sealed storage container, her slim left leg resting on the top while her black leather encased right leg dangled against the side.

Orphe swiftly entered the storage compartment and closed the hatch behind her.  The raven- haired Battle Sister smiled as Calybe unzipped the front of her skin-tight suit, freeing her milky white breasts.

"By the Emperor I want you!" purred Orphe, wrapping her arms around Calybe and kissing the girl hungrily.  Calybe held Orphe close, sticking her tongue inside Orphe's mouth and massaging her lover's.  Orphe grasped Calybe's right breast, caressing it with her slender fingers while her right hand slid inside the blonde girl's suit, finding her warm bush.  Calybe moaned with pleasure inside Orphe's mouth, gyrating her graceful hips as Orphe stroked her pussy, index finger slipping up and down her soft cunt.  When Calybe's pussy was wet and sticky, Orphe removed her finger and brought it to her violet-painted lips, slowly licking her friend's honey.

"Suck my cunt, you bad girl!" giggled Calybe, spreading her legs wide apart for Orphe.

Orphe kissed Calybe before kneeling upon the cold deck.  She tugged down Calybe's body sleeve, dropping it on the deck, then pressing her lovely face into the Battle Sister's crotch, nibbling on the blonde girl's tender, pink labia.  Calybe fell back, lying across the container with her bare legs opened wide for Orphe's sucking lips.  Orphe caressed Calybe's firm, ivory thighs as she dug her lips into the girl's cunt, her tongue diving deep into Calybe's yielding, moist folds.

"Terra!  That feels good!" groaned Calybe, her pelvis rolling, juices running freely from her gleaming slit.

Orphe savored Calybe's honey, collecting the drops with her tongue, nuzzling her pert nose in the Battle Sister's patch of curly gold pubic hair.  Orphe spread open Calybe's pussy and stroked the lips of the hole with her tongue.  The dark-maned girl sucked lightly upon Calybe's shivering clit, flicking the tip of her tongue over it again and again until the naked Battle Sister shuddered in ecstasy, biting her lower lip to stifle her orgasmic cries.

"Battle Sisters Orphe and Calybe!  Report to mustering chamber #11!" proclaimed a voice from the transport's intercom.

Orphe shot to her feet and adjusted her suit while Calybe hopped off of the storage container to retrieve her discarded body sleeve.  Orphe fought to keep from giggling as Calybe hopped from foot to foot, struggling back into her clothing.

"I'll see you at mustering," smiled Orphe, checking through the open hatch before departing.

"All attempts at communication have failed," reported Sister Superior Gunnhildr, her stern face eerily illuminated by the holo-display behind her.  "The frigate appears to be undamaged, but all power systems are off-line.  Our squad has been assigned to board the dead frigate and investigate what has happened."

"Weapons?" inquired Battle Sister Adoria.

"Standard bolt pistols and frags," replied Gunnhildr.  "Any other questions?"

The four assembled Battle Sisters were silent, standing rigidly at attention in their black body sleeves and matching boots.

"Excellent.  Report to shuttle bay #3 after you've adorned armor and weapons, we leave for the 'Heaven's Fire' in ten minutes!"
***

Orphe gazed out a small porthole, watching as the shuttle passed alongside the derelict frigate of the Imperium.  The beautiful, raven-haired girl frowned when she saw several strange unidentifiable pods attached to the hull of the warship.

"What are those?"

"Scanners read them as bio-tech, possibly Tyranid," replied Gunnhildr cooly.

The Battle Sisters shifted uneasily at the mention of Tyranids.  Tyranids were the alien scourge of the Imperium, they had very nearly overwhelmed human space when their immense hive fleets had appeared a decade before.  Adoria chambered a round into her bolt rifle, Damina swallowed and returned to reading her holy book.  Lowering her left gauntlet, Orphe sought out Calybe's hand and squeezed it for reassurance.

"Approaching docking bay.  Prepare for dock in three minutes," instructed the Sister Superior from the shuttle's cockpit.
***

Orphe played the torch attached to her left shoulder guard over the pitch-black interior of the passageway.  Hands clutching her rifle tightly, Orphe relaxed slightly when Calybe joined her side.

"Sisters Orphe and Calybe, go to the engine room and do a thorough search, I'll accompany Sisters Adoria and Damina to the bridge.  Check in every ten minutes."

"Yes, Sister Superior," acknowledged the two Battle Sisters.

"And try not to fuck each other on the reactor core," snickered Adoria, Damina giggling at her side.

"That's enough!  Move out!" hissed Gunnhildr sharply.

"Bitch," muttered Calybe as she followed Orphe down the dark passage.

"Anything on the scanner?" asked Orphe, licking her dry lips.

"Nothing," said Calybe with a head shake.  "But remember that Tyranids are very difficult to spot with scanners until they're practically on top of you."

"I'd rather have you on top of me," grinned Orphe, keeping her eyes alert before her.

"Naughty girl," smiled Calybe, shifting her rifle into a better position so she could keep a grip on her hand scanner as well.

The two Battle Sisters walked through the silent bowels of the frigate, getting closer to the engine room without incident.  The other Sisters hadn't run into any problems either, nor had they found any of the frigate's missing crew.

"I don't like this," murmured Calybe.  "It's too quiet."

A genestealer burst from an overhead vent and fell heavily on top of Calybe.  As the blonde Battle Sister screamed, Orphe spun and lowered her rifle.  Before Orphe could fire, two more genestealers hurled out of the open vent, diving towards her.  Orphe squeezed the trigger of her bolt rifle, slugs spewing out to rip into the two aliens.

"Orphe!  Help me!" howled Calybe as she was carried back down the passage by her attacker.

"Calybe!" roared Orphe, blasting one genestealer's head apart in a spray of purple gore.  The second genestealer ducked under Orphe's fire and slashed out with one claw, shredding the black armor over her right leg.  Gritting in pain, Orphe aimed at the alien and emptied her bolter clip, tearing the creature to bloody shreds.  Foul, reeking ichor dripped from the bulkheads while Orphe reloaded her weapon and staggered after her friend.  Orphe found another vent, this one upon the right-hand bulkhead, ripped open by razor-sharp Tyranid claws.  The Battle Sister knelt on the deck and touched a dark stain with a fingertip.  The liquid was blood, human blood.

"Calybe," whispered Orphe, tears sliding down her pale cheeks.  Quickly wiping her face, Orphe dropped her rifle, drew her pistol, and ducked into the ventilation shaft, determined to rescue her lover.
***

The first thing that Calybe noticed when she woke up was the incredible heat.  Sweat poured from the Battle Sister's body, drenching her black body sleeve.  Calybe tried to move, but her arms were bound above her head, fastened to the bulkhead by hard, unyielding, green excrement.  Tugging on her trapped wrists, Calybe didn't see the genestealer until it hissed softly at her.  The young Battle Sister stopped moving, she stared at the thing that loomed over her, its two pairs of claws twitching, its blue exo-skeleton covered by a thin film of slime.  The genestealer opened its jaws wide, releasing an incredibly long, gray tongue that oozed with more slime.  Calybe shivered, her training forgotten, only stark, primal fear remaining.  A soft whimper escaped Calybe's lips when the genestealer reached toward her and ripped open the front of her body sleeve, exposing her heaving tits and taut belly.  The genestealer leaned forward and flicked its agile tongue across Calybe's left nipple, the brown nub hardening reflexively.  The blue and purple alien licked Calybe's soft breasts again and again, covering them in cool slime.  Calybe panted, her body aroused by the alien's fondling even as her mind screamed in horror and loathing.  The genestealer grasped Calybe's tits in its claws and squeezed, its nails digging into her soft flesh, drawing beads of bright, red blood.  The creature licked the still-bleeding wound on Calybe's right temple, then lowered its muzzle to her breasts, licking the droplets that slid between her warm cleavage.

The genestealer tore away the rest of Calybe's body sleeve before seizing her thighs and pulling her legs apart.  Calybe screamed when the alien lowered its ovoid head between her thighs, its long, dripping tongue extending to taste her moist cunt.  The Battle Sister groaned, closing her eyes in shame while the Tyranid licked her pussy, its gray probe slipping into the wet depths of her vagina.  The genestealer held tightly onto Calybe's tight buttocks, its nails piercing her alabaster skin as it jabbed its tongue over and over into the girl's cunt, drawing gasp after gasp from the naked Sister's sensual mouth.  Calybe moaned weakly, her hips shivering as she climaxed, her pussy spurting honey across the startled genestealer's muzzle.  The Tyranid sniffed the musky discharge, then pushed its mouth against Calybe's hole, eagerly licking the cum that flowed from her wet cunt.
***

The ventilator shaft was tight, Orphe could barely slide forward through the dank shaft.  The heat grew as Orphe progressed, she continually had to stop to catch her breath and wipe perspiration out of her eyes.  The other Battle Sisters had failed to respond at the last check call, Orphe assumed that the Tyranids had ambushed them as well.  Doctrine said that she should return to the shuttle and allow the "Righteous Blade" to destroy the contaminated vessel, but Calybe was still onboard, so Orphe would remain until she had found and rescued the girl, there was no other option.

Orphe reached the end of the shaft and dropped into a large storage bay.  Cases of ordinance
and food lined the cavernous bay, everything draped in shadow.  The Battle Sister ran her torch across the metal cases, pistol held lightly in her right gauntlet.  The chamber was very hot, soon Orphe's face was dripping with sweat.  The air was heavy, filled with a musky aroma that made Orphe wet almost instantly, she blushed and concentrated on finding her captured friend.  Passing the rows of storage pods, Orphe emerged into a clear space, her eyes widening in shock.  Here was the crew of the "Heaven's Fire", bound with hardened slime, trapped against the bulkheads while alien life gestated inside their imprisoned bodies.  Swallowing a mouth full of bile, Orphe walked through the ranks of crewmen, searching for Calybe.

"Calybe!  Calybe, where are you?" demanded Orphe sharply.

"Kill us, kill us!" begged the crew of the Imperial frigate.

"Orphe," gasped Calybe from the far side of the bay, her wrists bound above her head by sticky slime, her lithe body naked and marred by scratches over her breasts and along her thighs and buttocks.

"Hang on, Calybe!" soothed Orphe, quickly walking over bound crewmen to reach the imprisoned Sister.

Genestealers dropped from the bulkhead above Orphe, hissing loudly with rage.  Orphe fired her bolter pistol, knocking two charging aliens off their clawed feet.  Movement from behind Orphe forced the Sister to spin on her boot heel, firing a line of bolts that slew three more creatures, their green blood filling the dank air around them.

"Orphe!  Behind you!" groaned Calybe loudly.

The genestealer slammed into Orphe, thrusting her off her feet.  The Battle Sister fell on top of a bound crewman, his eyes wide with shock, bright blue veins covering his corpse-pale face.  The Tyranid's sharp claws tore into Orphe's armor, shredding metal like wet paper.  Orphe was rolled onto her exposed back, the genestealer pressing down on top of her, clammy drool splashing across her face.  Orphe raised her pistol, but the genestealer slapped it out of her hand, sending it into the ravenous dark.  Irresistible claws grasped Orphe's head and held it still while the genestealer drew close, its hot breath washing across the Battle Sister's lovely face.

"Orphe!  No!" howled Calybe in despair.

Orphe's mouth was forced open, and the genestealer slipped its long, fat tongue between the girl's jaws.  The alien tongue pulsated inside Orphe's mouth, swelling with obscene alien life.  A thick, syrupy fluid poured from the genestealer's tongue into Orphe's throat.  The raven-maned Battle Sister choked, unwilling to swallow the foul excrement from the alien's mouth.  The genestealer kept its mouth over Orphe's, locked in an awful kiss.  Helplessly, Orphe finally swallowed the alien discharge, her throat burning as the liquid advanced inside her.

"Oh, no, Orphe," wept Calybe, her bare breasts quivering with grief.

The genestealer released Orphe.  The Battle Sister fell limply onto the deck, her body occasionally twitching as alien genes invaded and made her body their home.  The Tyranid genetic material finally settled inside the girl's womb, taking nourishment from Orphe, using it to grow another genestealer to serve the Hive.  The genestealer removed Orphe's armor, bound her wrists with slime that quickly hardened in the humid air.  Orphe lay upon her back, uncaring while the genestealer fondled her with its claws, slashed away her remaining clothing, and explored her ripe, young body.  The Battle Sister's naked body was pleasantly numb, beyond pain while the Tyranid within her grew to maturity.
