Aaron's finger twitched. That single, shaking flick of muscle sealed it. YES.
The cave shifted.
Pain detonated in his bones before the mask even finished its whisper. His spine arched like lightning had hit him, snapping loud as vertebrae stretched and bent into angles no human body should survive. He tried to scream, but his throat split open mid-sound, muscles tearing as sap-slick cords shoved through his skin. His jaw unhinged, teeth cracking as green resin dribbled down his chin. His ribcage burst outward with a crunch, branches splitting through flesh and curling around him like a cage.
The Lustrix didn't let him blackout. No mercy. Every second of it slammed into him raw — the sensation of bark threading under his skin, veins turned to root, his blood boiling into resin. His hands clawed at the stone until the fingers shattered, bones blooming into thorned stalks that pulsed as though alive. His legs ripped apart down the middle, marrow splitting into fibrous roots that writhed and burrowed into the cave floor. He wasn't even human anymore — a pile of meat tangled with vines, screaming so high it didn't sound human.
And still the mask forced him forward.
Emily was still lying there in the mess of blood and cum, twitching faintly. Her body was shredded, holes drooling ruin, eyes glassy. The HUD burned open:
[- LUSTIRX: TARGET ONLINE -]
•— NAME: EMILY CLARKE
•— AGE: 22
•— SPECIES: HUMAN
•— VITALITY: 7%
•— REPRODUCTIVE STATE: NONVIABLE
•— NEURAL STATE: COLLAPSING
Aaron choked inside his new body, begging the mask to stop. But the vines answered instead. They slid across the stone, slick with sap, curling around Emily's wrists, ankles, throat. She whimpered weakly, foam flecking her lips. Then the vines spread her open.
A thick root uncoiled from Aaron's chest, dripping resin like hot wax. It pressed into Emily's ruined cunt — and rammed inside. She screamed, a broken animal cry, as blood sprayed. The sap hissed through her insides, burning and sealing, trying to knit her walls back together even as the root shredded them wider, tearing through scar tissue, forcing her body to rebuild around the invasion. Every thrust made her pussy gape open then slam shut again, caught in a cycle of breaking and mending.
Another root plunged into her ass, jagged edges splitting the rim wider until it split into raw meat. Sap filled the wound instantly, hissing, stitching her in jerks. Aaron gagged, screaming from inside his chest as he felt the vines moving, pumping into her, spraying her full until it poured back out.
The HUD ticked mercilessly:
•— Vitality: 14%
•— Vaginal Cavity: Partial Restoration
•— Anal Cavity: Partial Restoration
•— Neural Response: Returning
Emily's chest heaved faster, head thrashing side to side, throat working around screams that shredded into sobs. But the Lustrix wasn't finished.
Two thinner roots slid up her body, curling around her tits. They stabbed into her nipples, punching holes straight through the buds. She shrieked, back arching, as the roots burrowed deep into her milk ducts, drilling until they split flesh open. Sap pumped in hot, filling her breasts until they swelled grotesque, skin stretching shiny as fluid sloshed inside. Her nipples gaped around the vines, leaking green and blood in long trails down her stomach.
The HUD blinked:
•— Mammary Tissue: Breeding Channel Created
•— Restoration: Expanding
Aaron's head shook violently, sobs choking out of him. "Please! No more! She's human! She can't—" but the words broke as more roots ripped free of his alien torso. They shoved into Emily's mouth, prying her jaw open, jamming sap straight down her throat until her belly bulged. Roots twisted in her nose, ears, every hole the body had, pumping her full until she was just a leaking sack of resin and blood.
Her eyes rolled white, body spasming, but her heart kept hammering in her chest. The HUD climbed:
•— Vitality: 27%
•— Neural State: Stable Seizure
•— Restoration: ACTIVE
Aaron couldn't breathe. His chest — whatever part of him was still chest — felt like it would cave in. He was forced to watch as Emily's ruined body was "healed" not into what she had been, but into something worse: a vessel full of holes, every cavity open, forced wider, dripping with resin that bound her together only so she could be filled again.
Her pussy gaped permanently now, sealed raw but always stretched. Her asshole was a leaking funnel, sap drooling. Her tits twitched as the vines pistoned through the nipple-holes, sap spraying from them like broken faucets. She wasn't even screaming anymore — just gagging around the roots, her eyes leaking tears while her stomach inflated with the constant filling.
The Lustrix whispered in Aaron's head, sugar rotting on his brainstem: See? She will never break. She will never die. She is yours.
The HUD flared one last time:
•— Vitality: 42%
•— Body State: Restored for Use
•— Breeding Channels: CREATED
Aaron collapsed inside his own alien frame, roots still twitching inside Emily's every hole, his mind clawing for escape, his body nothing but a puppet. And the mask purred, Now… let's see how long she lasts.
The vines still writhed in Emily, her body jerking in rhythm as if she were nothing but a leaking pump, her swollen tits slapping wet each time the roots rammed into the nipple-holes. Resin dribbled from every orifice, pooling around her in sticky lakes, the cave floor gleaming green and red. Her face was locked open, gagging, eyes glazed, body kept alive by nothing but sap burning through her veins.
Aaron prayed for it to end, but the Lustrix wasn't finished. His new body twisted, the roots dragging his broken form toward the other figure on the cave floor.
The alien woman. Kly'thel.
She was still breathing, faintly, but barely more than a twitching carcass. Her pale-blue flesh was ruined from earlier, pussy and ass ragged tunnels drooling cum and blood, her chest hitching like a broken machine. The leash of roots curled around her ankles and wrists, and in one violent snap she was lifted off the stone, dangling in the cave light like a piece of meat waiting to be carved. Her eyes fluttered weakly, head lolling to the side, but the Lustrix didn't care.
Aaron felt it before he saw it. A branch tore out of his groin, bark cracking, splitting down the middle until it wasn't just a vine but a cock — if a cock could be a writhing log of thorns and roots twisted together, veined with glowing resin that dripped like molten wax. It pulsed hungrily, every knot along it flexing like a beating heart. The Lustrix guided it forward, pressing it against Kly'thel's gaping cunt.
There was no push, no tease. Just one brutal thrust.
The thorned cock slammed into her body so hard her scream ripped the air, high and raw, blood spraying out around the shaft as it split her open wider than before. Her hips snapped against the force, legs kicking weakly as her pussy bulged around the mass. Roots erupted inside her, spiraling deeper until they burst from her stomach, ripping through muscle and skin, jutting out of her like she'd been skewered.
She tried to writhe, to pull away, but the vines holding her limbs tightened until bones cracked, pinning her there as nothing but a sheath. Her cunt stretched so wide it tore up her body, the hole no longer ending at her pelvis — now it was just one long, gaping wound stuffed with writhing bark. Resin and blood poured down her thighs in thick streams, sizzling where it hit the ground.
Aaron's scream joined hers, though not from the same throat. He felt every thrust, the alien cock grinding, ripping, reshaping her into a permanent cock-sleeve. He could taste her insides in his skull, like bile and iron, every nerve in his stolen body making her agony his own.
The Lustrix whispered through the roaring pain: An ornament for you. She will hang here. Always ready. Always open.
The cock pushed deeper, punching through her womb, into her chest, forcing her ribcage apart. Sap sprayed inside her, stitching her around the invader, binding her torn organs not to heal her — but to fuse her to it. Her insides wrapped the shaft like wet cement setting around rebar. She convulsed, screaming wetly as blood poured out of her mouth, mixing with foam.
Then another branch tore from Aaron's alien frame, this one thinner, tipped with spikes. It rammed into her ass, forcing through torn muscle, splitting her back passage open until it ripped into her spine. Her body bowed around the intrusion, vertebrae cracking one by one as the root threaded itself through her bones. With every inch, more roots broke off, spreading through her nerves, anchoring her body to the cock embedded in her cunt.
She wasn't being fucked anymore — she was being mounted.
Emily gurgled weakly on the floor, gagging around the vines flooding her throat, her body jerking every time the sap pumped more into her. And above her, Kly'thel hung from Aaron's crotch like an obscene decoration, her body stretched around the living cock, her insides fused so she couldn't slide off. Her ruined holes spasmed, drooling red and green, but there was no escape.
The HUD burned cold in Aaron's vision:
[- TARGET ACQUISITION -]
•— NAME: KLY'THEL
•— AGE: 131
•— SPECIES: ???
•— REPRODUCTIVE VIABILITY: HIGH
•— CURRENT STATE: PERMANENT HOST / ORNAMENT
Her body jerked each time the cock pulsed, resin pumping into her stomach, her womb, her lungs, filling her from the inside until she sagged heavier on the shaft. Her eyes rolled, veins glowing faint green as the sap crawled through her bloodstream, keeping her alive only so she could keep hanging there. Her ruined pussy clamped desperately, but the roots just dug deeper, locking her body tighter to the cock until she was nothing more than a sheath, a living cock ornament dangling in constant violation.
Aaron's mind cracked against the reality, his thoughts shredded by her muffled screams and the tearing sensation echoing through his stolen nerves. He sobbed, throat raw, but the mask only purred in the back of his skull: Two vessels. One body. And you… are not done yet.
