The journey through the rift was instantaneous and disorienting. One moment Lirien was sprawled on the ritual altar, body still trembling from the aftershocks of her forced climax, the thick warmth of Valthorax's release slowly leaking down her thighs. The next, cold night air whipped around her as shadowy tendrils lifted her effortlessly into the Demon Lord's arms.
Valthorax carried her as if she weighed nothing, his massive frame cutting through the veil between realms. Lirien's head rested against his bare, heated chest, the rhythmic thud of his ancient heart oddly steadying despite the chaos in her mind. The binding pulsed inside her like a second heartbeat — warm, insistent, and undeniably linked to him. Every brush of his skin against hers sent sparks of unwanted pleasure dancing across her nerves.
"You're quiet, little slave," Valthorax rumbled, his deep voice vibrating through her. His crimson eyes glowed faintly in the darkness as they emerged into a vast cavernous hall. "No more sharp words? Has the sealing already tamed that defiant tongue?"
Lirien forced herself to lift her head, glaring up at him even as her cheeks burned. "Go to hell."
A low, dangerous chuckle escaped him. "We are already there."
The Obsidian Citadel rose around them like a living nightmare carved from midnight itself. Towering spires of black glass and jagged stone pierced the starless sky. Rivers of molten crimson lava flowed through channels in the floors and walls, casting everything in a hellish red glow. The air smelled of sulfur, smoldering incense, and something darker — raw power and ancient lust.
Servants — lesser demons with scaled skin and glowing eyes — bowed deeply as Valthorax passed, none daring to look directly at the human woman in his arms. Lirien felt exposed in the sheer black silk garment he had conjured for her earlier; it clung transparently to her curves, barely covering the evidence of what had just happened in the temple.
They ascended a grand staircase that seemed to spiral endlessly upward. Finally, Valthorax pushed open massive double doors with a casual wave of his hand. The chamber beyond was his private sanctum — enormous, opulent, and unmistakably masculine. A colossal bed dominated the center, draped in black silk sheets that shimmered like liquid shadow. Obsidian pillars rose to a vaulted ceiling painted with ancient demonic runes that pulsed softly. One entire wall opened onto a balcony overlooking a sea of lava and jagged mountains.
Valthorax set her down gently on the edge of the bed. Lirien immediately scooted back, pulling her knees to her chest in a futile attempt at modesty. Her body, however, betrayed her. The binding made her skin hypersensitive; the cool silk beneath her thighs felt like a lover's caress, and the ache between her legs had already begun to rebuild into a low, throbbing need.
"Rest if you wish," Valthorax said, turning toward a side table where a crystal decanter of dark wine waited. He poured two goblets, the liquid inside swirling with faint sparks of magic. "But do not think the night is over. The bond demands frequent sealing to stabilize my power in this realm… and to awaken yours."
Lirien's breath hitched. "You mean you're going to fuck me again."
He turned, offering her one goblet. His towering form cast a long shadow over her. Up close in the better light, she could see every detail — the way his obsidian skin caught the red glow like polished stone, the subtle cracks of glowing magma-like veins running beneath it, the sharp definition of muscle across his chest and abdomen. His horns curved elegantly, deadly. And between his powerful thighs, even at rest, the heavy outline of his cock was visible beneath the shadowy cloth he wore.
"Crude, but accurate," he replied, voice smooth as velvet over steel. "Drink. It will ease the soreness and heighten the pleasure. You will need both."
She hesitated, then snatched the goblet and took a defiant gulp. The wine tasted like dark cherries and liquid fire — sweet, potent, and instantly spreading warmth through her veins. Her nipples tightened visibly against the sheer fabric.
Valthorax watched her with predatory satisfaction. "Good girl."
"Don't call me that," she snapped, even as another wave of heat pooled low in her belly.
He set his own goblet aside and approached the bed slowly, each step deliberate. "You are mine now, Lirien Voss. Bound by blood and shadow. Your body knows it, even if your mind still fights." He reached out, tracing one claw lightly down her arm. The touch left a trail of tingling pleasure. "Feel how it calls to me already."
Lirien shivered, hating how her thighs pressed together instinctively. "This isn't me. It's your cursed magic."
"Perhaps," he conceded, climbing onto the bed with graceful power. The mattress dipped under his weight. He loomed over her, caging her with his arms on either side of her head. "But soon you will beg for it without the excuse of magic. You will spread your legs willingly and ask your Demon Lord to fill you again."
His words sent a shameful thrill through her. The binding amplified everything — making her clit throb and her pussy grow slick with fresh arousal. She could feel her own wetness starting to coat her inner thighs.
Valthorax inhaled deeply, nostrils flaring. "Such a sweet scent. Already dripping for me again." He lowered his head, lips brushing the shell of her ear. "Tell me, little slave… did you enjoy how I stretched that tight human cunt? How you came so hard around my cock while those cultists listened?"
Lirien's face burned with humiliation and unwanted desire. "Shut up."
He chuckled darkly and captured her mouth in a dominating kiss. His tongue — longer, rougher — invaded her, tasting the wine and her own reluctant moans. One large hand slid down her body, cupping a breast through the silk and pinching the nipple until she gasped into his mouth.
When he pulled back, a thin string of saliva connected their lips. "On your knees," he commanded, voice dropping into a growl. "I want to see how well you can take me from behind this time. Show your master that defiant spirit while you present that pretty ass."
Lirien's heart raced. Part of her wanted to refuse, to fight. But the binding — and the growing heat in her blood — made resistance feel impossible. Slowly, trembling with a mix of anger and arousal, she turned over and rose onto her hands and knees.
Valthorax made a low sound of approval. His claws shredded the sheer silk garment with precise strokes, leaving her completely naked. He positioned himself behind her, his massive cock already hard and throbbing, the thick head nudging against her soaked entrance.
"So wet," he murmured, one hand gripping her hip while the other tangled in her long dark hair, pulling her head back gently but firmly. "This cunt was made to be claimed by demon cock."
He pushed forward in one long, powerful thrust, burying half his length inside her. Lirien cried out at the intense stretch, the burning pleasure that bordered on pain. The ridges along his shaft dragged against her sensitive walls, lighting up every nerve.
"Fuck… too big…" she whimpered, fingers clutching the sheets.
"You can take it," Valthorax growled, thrusting deeper until his hips pressed flush against her ass. "All of it. Every inch belongs inside you now."
He began to move — slow, deep strokes at first that let her feel every thick vein and demonic ridge. Then harder, faster, the sound of skin slapping skin echoing through the grand chamber. Each thrust pushed her forward on the bed, her breasts swaying heavily beneath her.
Lirien's moans grew louder, uncontrollable. The binding turned every sensation into ecstasy. Her inner walls clenched greedily around him, milking his cock as another orgasm built rapidly.
"That's it," he praised roughly, leaning over her back. His chest pressed against her, one hand reaching around to rub tight circles on her swollen clit. "Scream for your Lord. Let the entire citadel hear how eagerly his eternal slave takes her master's seed."
Pleasure crashed over her suddenly. Lirien came hard, her pussy spasming wildly around his thrusting cock, a broken cry tearing from her throat. The rush of energy flowed into Valthorax, making his runes glow brighter and his thrusts turn savage.
He fucked her through her climax without mercy, drawing it out until she was shaking and sobbing with overstimulation. Only then did he bury himself to the hilt with a deep, guttural roar, flooding her once again with hot, magical cum that triggered another smaller orgasm in her exhausted body.
They collapsed together onto the sheets, his massive frame carefully not crushing her. Valthorax remained inside her, pulsing with the last spurts, one arm wrapped possessively around her waist.
Lirien lay there panting, mind hazy with pleasure and conflicting emotions. The bond hummed stronger now, a dark thread connecting their essences.
"You… bastard," she whispered hoarsely, no real heat left in the words.
Valthorax pressed a surprisingly gentle kiss to the back of her neck. "Rest, my slave. Dawn will bring more training… and the first fragments of your own power awakening."
As exhaustion pulled her under, Lirien realized with a mix of dread and dark thrill that this was only the beginning of her eternal binding.
She was his.
And some treacherous part of her was already starting to crave it.
