Synopsis
Cal died exactly the way he lived: hunched over a sticky keyboard at 4 AM, chasing a dopamine hit in a trashy civilization-building smut novel. Instead of a game-over screen, he wakes up on a freezing stone altar in the Realm of Aethelgard. His summoner? General Xyliana, a ruthless, impossibly thick demonic warlord with a shattered mana core and a desperate need to recharge. The only way she can survive the war is by draining raw energy, and Cal’s newly transmigrated body is practically leaking it. The catch? The transfer process requires a very physical, very intimate connection. He thought he was reading the fantasy; now he has to survive it.

Chapter 1 - The Gooner's Requiem

[A cramped studio apartment, Earth / The Obsidian Spire, Aethelgard - Unrecorded Epoch, Midnight]

The human body is a surprisingly resilient machine, capable of enduring extreme temperatures, physical trauma, and prolonged starvation. It is not, however, designed to run on a toxic slurry of lukewarm energy drinks, stale instant ramen, and seventy-two consecutive hours of high-definition, unapologetic smut.

Cal knew this, objectively. He just didn't care.

He sat hunched in his computer chair, a posture that resembled a cooked shrimp. The only illumination in the suffocatingly small studio apartment came from the harsh, blue-white glare of his dual monitors. The air in the room was thick, carrying the distinct, sour smell of cheap body spray trying and failing to mask days of unwashed sweat and the salty, lingering musk of his own relentless habits. A rusted box fan rattled in the corner—thwack-thwack-thwack—circulating the stale air without actually cooling anything down.

Cal was twenty-four, carrying a flat GPA, a mountain of student debt, and a social life that had flatlined sometime during his sophomore year of college. The outside world was a rigged, exhausting game played by people with better genetics and trust funds. Inside, though? Inside the glowing borders of his screen, he was a god by proxy.

His right hand rested heavily on the mouse, index finger twitching on the scroll wheel. His left hand was currently busy massaging the aching, bruised flesh of his own erection through the worn cotton of his sweatpants.

He was reading The Emperor's Jade Pavilion, a webnovel of dubious literary merit but unparalleled explicit detail. The protagonist—a flawless, overpowered self-insert—was currently backing a frosty, untouchable elven princess against a marble pillar. Cal's breathing grew shallow. His cock twitched, a heavy, hot throb pressing against his palm. He had been edging for the better part of four hours, waiting for this exact chapter.

"Come on," Cal muttered, his voice raspy from disuse. "Just rip the dress. Stop talking about the politics and rip the fucking dress."

He scrolled down, his eyes skimming past a block of text describing the kingdom's tax policy to get to the good stuff. His heart hammered a frantic, irregular rhythm against his ribs. It had been doing that a lot lately. A weird fluttering sensation, like a trapped moth behind his sternum.

He found the paragraph. The elven princess finally dropped her icy facade. The protagonist's hands found her hips.

Cal gripped himself harder, his hips automatically bucking upward in the rolling office chair. The friction was searing. He was so close. The pressure coiled at the base of his spine, tight and heavy, ready to snap and paint the underside of his desk.

Then, the moth behind his ribs turned into a sledgehammer.

Wham.

A spike of pure, blinding agony erupted in the center of his chest. Cal gasped, his fingers spasming, dropping his cock entirely. The mouse clattered against the desk. He tried to draw a breath, but his lungs refused to expand. An invisible, crushing weight settled over his chest, driving the air from his body.

The pain didn't recede. It radiated outward, a cold, crawling numbness shooting down his left arm and creeping up the side of his neck. His jaw locked tight.

"Ghhh-uh," he choked out, his vision swimming. The text on the monitor blurred into a smear of white and black.

Is this it? he thought, a wave of profound, pathetic realization crashing over him. I'm having a heart attack. I'm literally dying right now.

He tried to reach for his phone, buried somewhere under a pile of discarded snack wrappers, but his arm wouldn't obey. His body felt like it was encased in wet cement. The room spun, the rhythmic thwack-thwack-thwack of the fan slowing down, stretching into a distorted, underwater drone.

It was absurd. It was humiliating. He wasn't going to die saving someone from a burning building. He was going to die with his pants shoved halfway down his thighs, surrounded by crusty tissues, right before the elven princess got railed.

The blue light of the monitor faded into a suffocating, absolute black. The pain spiked one last, agonizing time, and then... nothing.

Silence.

Not the muffled, traffic-heavy silence of a city apartment, but an ancient, heavy quiet that pressed against the eardrums.

Cal's consciousness returned slowly, piecing itself together like shattered glass. The first thing that registered was the temperature. He was freezing. The ambient heat of his computer tower was gone, replaced by a biting, subterranean chill that seeped directly into his bones.

The second thing was the smell. The stale ramen and sour sweat had vanished. Instead, the air was thick, heavy, and layered. He smelled sharp, crackling ozone—like the atmosphere right after a violent lightning storm. Beneath that was the overwhelming, intoxicating scent of crushed night-blooming jasmine, mixed with the unmistakable, metallic tang of fresh copper blood.

Cal gasped, his eyes snapping open.

He was not in his chair. He was lying flat on his back on a massive, perfectly circular slab of polished obsidian. The stone was unyielding and ice-cold against his bare skin.

Wait. Bare skin?

He tried to sit up, but his muscles felt foreign, heavy and overly responsive. He pushed himself up onto his elbows, his vision clearing in the dim light. The chamber around him was vast, constructed from jagged, unworked black stone. Floating orbs of violet fire bobbed near the vaulted ceiling, casting long, twisting shadows across the floor.

He looked down at himself and his breath hitched.

The soft, doughy stomach he had cultivated over years of neglect was gone. His torso was lean, corded with tight, unfamiliar muscle. His skin was pale, unmarked by the acne scars that used to dot his shoulders. He was completely naked, and to his absolute shock, his cock was resting heavy and thick against his thigh, currently soft but undeniably larger than he remembered.

Before the panic could fully set in, a sound cut through the heavy silence.

Click. Clack.

Footsteps. Slow, deliberate, and heavy. Boot heels striking the stone floor, approaching from the shadows beyond the altar.

Cal froze, his heart resuming that frantic, hammering rhythm, but this time it was fueled by pure adrenaline, not plaque buildup.

A figure stepped into the violet light.

Cal forgot how to breathe. He had spent his entire life studying the anatomical proportions of fictional women, ranking 2D illustrations on forums, and critiquing character designs. The woman walking toward him shattered every metric he possessed.

She was tall—easily over six feet—moving with a liquid, predatory grace that commanded the space around her. Her hair was a startling shade of metallic silver, thick like spun wire, falling in heavy, cascading waves all the way down past her narrow waist. Her face was a sharp, heart-shaped weapon of aristocratic perfection. High, slicing cheekbones framed eyes the color of fractured emeralds, the pupils narrowed into vertical, reptilian slits that locked onto Cal with terrifying intensity.

But it was her body that made Cal's throat go dry.

Broad, athletic shoulders tapered down to an impossibly narrow, indented waist. Her chest was heavy and full, the soft, pale swells of her breasts spilling over the top of a scorched, skintight leather corset. The dark material was torn in several places, biting viciously into the flesh of her underboob, emphasizing her sheer size. Below the corset, her hips flared out dramatically into thick, muscular thighs, encased in battered leather greaves. A glowing, intricate black tattoo—resembling a jagged crown—rested on her left collarbone, pulsing rhythmically with a faint, dark light.

She stopped at the edge of the obsidian altar. The smell of jasmine and ozone radiating off her was intoxicating, thick enough to taste on the back of his tongue.

She looked down at him. Her expression was entirely unreadable—a mask of cold, assessing calculation.

He is remarkably unblemished, Xyliana thought, her emerald eyes tracking the rapid rise and fall of his chest, noting the way his pupils dilated as he stared at her. And the mana density radiating from his core... it is almost blinding. The summoning circle didn't just pull a soul; it pulled a reservoir.

"You," she spoke. Her voice was pure velvet wrapped over broken glass, low and vibrating with a latent, terrifying power. "You are the one the void spat out."

Cal opened his mouth, but only a dry squeak emerged. He tried again, swallowing hard. "Where... who are you?"

The corners of her full lips twitched upward into a smirk that held absolutely no warmth. It was the look of a wolf inspecting a particularly plump rabbit.

"I am General Xyliana of the Crimson Vanguard," she said, resting a gauntleted hand on the hilt of a massive, serrated broadsword strapped to her hip. "And you are currently occupying my private summoning altar."

She leaned forward, bracing one hand on the cold stone right next to his hip. The movement caused her heavy breasts to sway slightly, the torn leather creaking in the quiet room. Cal's eyes flicked downward instinctively, and he felt a completely involuntary, deeply humiliating twitch of blood rushing to his groin.

Xyliana noticed. Her slitted eyes dropped to his lap, watching the undeniable shift in his anatomy as his cock began to stir against his thigh. The smirk on her lips widened, turning genuinely wicked.

"My core was shattered in the siege of the Ashen Wastes," she murmured, her voice dropping an octave, becoming a rough, sultry purr that sent a shiver straight down Cal's spine. "I require a massive infusion of raw, unrefined Eros mana to rebuild it. I was prepared to drain a hundred lesser demons to achieve it."

She reached out with her free hand. Her fingertips, clad in fingerless leather gloves, lightly traced a line up the center of his chest. Her touch was freezing cold, yet it left a trail of sparking, electric heat in its wake.

"But you..." she whispered, leaning closer until the scent of her sweat and jasmine completely overwhelmed him. "You are overflowing with it. I can taste it leaking from your pores."

She shifted her weight, smoothly lifting one heavily muscled leg and planting her knee on the altar, effectively caging him against the stone.

Cal's breathing hitched. The fear was still there, a bright, flashing warning light in the back of his mind, but it was rapidly being drowned out by the sheer, overwhelming physical reality of the terrifying, gorgeous monster girl hovering over him. His body was reacting without his permission. He was getting rock hard, the thick ridge of his cock bobbing up to press against his own stomach.

"Wh-what are you going to do?" Cal managed to stammer out, his hands gripping the edge of the obsidian slab.

Xyliana's glowing emerald eyes locked onto his, her silver hair falling forward like a curtain, trapping them in a private, electrically charged bubble.

"I am going to take what I need," Xyliana said softly. "And we are going to see if your fragile human body can survive the extraction."
