Chapter 1: The Bite That Changed Everything
The itch on Jacob’s neck was a tiny, precise rebellion against the monotony of his Thursday morning. He slapped at it absently, his other hand keeping a worn copy of Leaves of Grass propped open against the courtyard bench. His thumb came away smeared with a miniscule crush of black and a dot of his own blood. A fly. He wiped it on his jeans, muttered “gross,” and went back to Whitman.
By eleven, the itch was gone, but a deep, gnawing hunger had taken its place. It wasn’t normal. It felt hollow, cellular. He ducked out of his Modernism seminar early, beelining for the student union. He bought two cheesesteaks and a chocolate milk, devouring them at a sticky table in the corner. The food hit his stomach like stones in a well—a dull, unsatisfying thud. He still felt empty.
His shirt felt weird across the shoulders first. Like it had shrunk in the dryer. He tugged at the collar during his poetry workshop, struggling to focus on the critique of his villanelle. The professor’s words blurred into a drone. His back began to ache, a low burn between his shoulder blades, as if he’d done a hundred pull-ups in his sleep.
“Dude. You okay?” His roommate, Dave, fell into step with him after class. Dave was a econ major with the build of a former high school linebacker going soft. He squinted at Jacob. “You look… puffy. You lifting?”
“What? No.” Jacob hitched his backpack higher. The strap dug into a new, unfamiliar ridge of muscle. “Allergies, maybe.”
“Seriously. Your arms are about to pop out of that thing.” Dave poked Jacob’s bicep. It felt hard, dense. “What’s your secret? ’Roids?”
Jacob forced a laugh that sounded thin. “Yeah, Dave. I’m juicing. Between Whitman and Keats.”
Back in their dorm, he stood before the narrow mirror nailed to the back of the door. He looked like himself, mostly. A little more defined around the jaw, maybe. His eyes seemed a sharper blue. But when he pulled his t-shirt over his head, the breath caught in his throat.
His chest wasn’t just fit. It was sculpted. His pectorals were full, sharply etched slabs under skin that looked tighter, smoother. His abs, previously a soft suggestion, were now a clear, defined six-pack. He twisted, seeing the furious cut of serratus muscles, the sweep of his lats flaring out into a V that tapered to his waist. He looked like a fitness model airbrushed into his own life.
He stared, numb. This was impossible.
A sharp, searing pull in his thighs made him gasp. He watched, horrified, as the denim of his jeans darkened along the seams of his quadriceps. A low rrrrrip echoed in the quiet room. The fabric split open from mid-thigh to knee, revealing skin that was hairless, impossibly sinewy. He staggered back and sat hard on his bed, the frame groaning in protest.
His phone buzzed. Dave. Where u at? Party at Sigma Chi. Chicks. Come on.
The word “chicks” sparked nothing. A flat, empty space. Instead, he pictured Liam, the brooding guy from his poetry workshop who always wore black and wrote about shipwrecks. The image of Liam’s hands, long-fingered and stained with ink, flashed in his mind, and a heat that had nothing to do with the mutation rushed through him. It was a clean, sharp desire, terrifying in its clarity. He pushed it down.
He had to get out. He threw on a hoodie, the only thing loose enough to contain his new frame, and slipped into the hallway. The walk across campus was a gauntlet. A group of frat guys carrying a keg stopped their conversation to watch him pass. One whistled, low and appreciative. “Damn, bro.” A girl walking the other way with her friend did a double-take, her gaze lingering on the hoodie stretching across his chest. Her friend whispered something, and they both giggled.
He felt like a specimen. A piece of art. He kept his head down, the hunger roaring back, sharper now.
In the shadowy campus convenience store, he loaded his arms with protein bars, hard-boiled eggs, a family-sized roast chicken. The cashier, a lanky guy with gauges in his ears, rang him up slowly, his eyes roaming over Jacob’s hoodie, down to the torn jeans. His gaze was a physical touch.
“Big night planned?” the cashier asked, a slow smile playing on his lips. His voice was warm, knowing.
“Something like that,” Jacob mumbled, shoving cash across the counter. The guy’s fingers brushed his during the change. The contact was electric, sending a jolt straight to Jacob’s core. He flinched, grabbed his bags, and fled.
Back in the sterile silence of his room, he tore into the food, shredding chicken with his teeth, swallowing protein bars whole. The hollow feeling began to subside, replaced by a thick, humming fullness. He stripped again, standing before the mirror in just his boxers.
The reflection was a stranger. A gorgeous, powerfully built stranger. Every line was perfect, exaggerated. He ran a hand over his stomach, the skin unbelievably smooth. He thought of the cashier’s smile, the frat guy’s whistle. He thought of Liam’s inky hands.
A different kind of heat pooled low in his belly. His face flushed. This was wrong. This wasn't him.
He leaned closer to the mirror, searching his own eyes for something familiar. In the reflection, just over his own stunning shoulder, he saw it. On the windowsill, near where he’d been reading that morning.
The fly. Not dead. Twitching. One wing was bent, but its body was grotesquely swollen, pulsating, as if it had gorged itself on something vast. Its tiny, multifaceted eyes seemed to stare right back at him.
A cold understanding seeped through the warmth of his new skin. This wasn't an accident. This wasn't a blessing.
He lifted a trembling hand, the perfectly formed muscles in his forearm coiling. He brought it down on the windowsill with a sharp, final crack.
When he lifted his palm, the fly was a wet, black smudge. He looked from the mess on his hand to the god in the mirror, and a wave of nauseous dread, cold and absolute, washed over the hunger and the confused, unwelcome desire.
Something had bitten him. Something had changed him. And it was just beginning.
The silence after the crack of his hand on the windowsill was absolute. The only sound was the ragged pull of his own breath. He stared at the pulpy residue on his palm, then back at the impossible reflection. The god in the mirror stared back, its eyes wide with a fear Jacob Miller recognized as his own.
A key rattled in the lock.
Jacob scrambled, grabbing his discarded hoodie and yanking it on just as the door swung open. Dave stumbled in, reeking of cheap beer and sweat. The party had come to him.
“Jac—whoa.” Dave froze, squinting. His eyes, glazed with alcohol, traveled from Jacob’s face down the exaggerated breadth of his hoodie, to the torn jeans. “The hell happened to you?”
“Nothing.” Jacob’s voice was too tight. He turned, pretending to examine his palm. “Gym. Went hard.”
“Bullshit.” Dave kicked the door shut and dropped his keys on the desk. “You hate the gym. You called it a ‘temple of vanity’ last week.” He took a stumbling step closer. “Did you get, like, a thing? A photoshoot? You look like a Marvel guy. Captain America, but, like… hotter.”
The word hung in the small room. Hotter. Jacob felt a flush creep up his neck. Dave’s eyes weren’t leaving him. They held a dumbfounded, drunk curiosity that felt like a physical touch.
“It’s late, Dave.”
“It’s like one.” Dave plopped down on his own bed, facing Jacob. He grinned, loose and easy. “C’mon. What’s the secret? You can tell me. Bros before… well, before whoever you’re turning into.”
Jacob’s heart hammered against his new, dense sternum.
The god in the mirror held a terrified boy inside it. Jacob could feel him screaming.
“Seriously, man. Let me see.” Dave pushed himself up from his bed, his movements loose and liquid from the beer. He crossed the small space in two strides. Before Jacob could step back, Dave’s hands were on his shoulders, pulling at the hoodie fabric. “What’ve you got under here?”
“Dave, don’t—” The protest was weak, choked.
Dave yanked the collar down, exposing Jacob’s shoulder and part of his chest. Dave’s drunken grin froze, then slid off his face. His fingers, still gripping the fabric, went still. “Holy shit.”
He wasn’t looking at muscle. He was looking at something impossible. The skin was too perfect, too smooth, like marble warmed to life. The definition wasn’t that of a gym rat; it was anatomical, as if the concept of a human body had been redrawn by a more idealistic artist. Dave’s breath hitched. His gaze was no longer curious. It was hungry.
A new sensation detonated in Jacob’s gut. It wasn’t the cellular hunger for protein. This was a sharp, pulling heat, centered lower. The way Dave looked at him—the dumb awe, the slack mouth—it fed something twisted and new. It felt good. Powerful.
Dave’s hand moved from the hoodie to Jacob’s chest. The touch was hot, heavy. “How?” he whispered.
Jacob didn’t answer. The heat was spreading, coiling tight. He could smell the beer on Dave’s breath, the cheap detergent on his shirt, the salt of his sweat. Every detail was amplified, vivid. He saw the pulse in Dave’s neck, the stubble along his jaw. A deep, resonant hum started in his own bones, a vibration of pure need.
Dave’s other hand came up, palm flattening against Jacob’s sternum. “You’re real,” he murmured, as if checking.
The hum became a roar. The control Jacob was clinging to—the fear, the confusion—snapped. It was too much. The touch, the look, the raw,陌生 power in his own veins.
He grabbed Dave’s wrist, the movement too fast, too strong. Dave gasped, his eyes widening, but he didn’t pull away. Jacob saw his own reflection in Dave’s pupils: a fierce, beautiful monster.
He shoved Dave back onto the bed. Dave fell with a grunt, staring up, not in fear, but in a kind of dazed surrender. The hum concentrated, a tsunami seeking a single point of release. Jacob trembled, a vessel too full. He was aware of the rough fabric of his jeans, the desperate ache, Dave’s parted lips.
It wasn’t pleasure. It was a seismic event.
With a choked, guttural sound, the climax ripped through him. It was violent, a wave of pure biological imperative. White flashed behind his eyes. His body arched, rigid.
Dave flinched, his eyes squeezing shut as a hot, wet stripe sprayed across his face and throat. It splattered over his cheek, his lips, into his open mouth. He sputtered, coughing.
Silence crashed back in, broken only by their ragged breathing.
Jacob staggered back, hollowed out, shame flooding the emptied spaces. Dave lay still, wiping his mouth with the back of his hand, staring at the glistening mess on his skin. He looked stunned, violated.
Then he blinked. He sat up slowly, touching his slick cheek. He brought his fingers to his eyes, examining the fluid.
A strange, focused clarity replaced the drunken haze in his expression. He looked from his wet fingers to Jacob, and for a flickering second, his eyes weren’t confused or angry. They were curious. Deeply, insatiably curious.
He slowly, deliberately, licked his fingers clean.
A sharp, pleasurable cramp seized Dave’s abdomen. He doubled over with a groan, his hands clutching his stomach. Jacob watched, frozen, as Dave’s shirt began to strain across the shoulders.
Jacob watched, frozen, as Dave’s shirt began to strain across the shoulders. A muffled pop sounded—a button pinging off the lamp. Then another. Dave groaned, a wet, pained sound from deep in his gut. He clawed at his abdomen, his fingers digging into flesh that was visibly hardening, rising.
“What… is…” Dave choked out.
His shoulders broadened, not with the soft slope of a linebacker, but with the sharp, cubed deltoids of a comic-book hero. The fabric of his shirt screamed, then split down the seam of his spine with a sound like ripping cardboard. Underneath, his skin was changing. A warm, rich umber pigment flooded across his back, washing over the old tan lines, turning the scattered moles into dark islands on a new continent.
Dave fell off the bed onto his hands and knees. His back muscles rippled and swelled like living things, lats fanning out, a deep canyon forming along his spine. His arms thickened, biceps and triceps swelling with each pained gasp. The bones in his face seemed to shift, his jaw squaring, his nose broadening slightly, his features resolving into a stark, handsome symmetry. His close-cropped hair grew out in tight, dark coils.
He tore at the remains of his jeans. The denim, already strained, exploded at the thighs. His legs erupted with muscle, calves knotting, quads becoming vast, sculpted hills. A low, continuous moan came from him, part agony, part something else.
Then, the final change. In the shredded wreckage of his boxers, his genitals swelled, growing prodigiously, impossibly large and thick, a blatant, hyper-masculine appendage that completed the transformation from a soft college kid into a monument of virile power.
The groaning stopped.
Silence, except for the humid roar of the room’s heater.
Dave knelt on the floor, naked, head bowed. His new body glistened with a fine sheen of sweat. He was enormous. Every muscle was defined, not just visible but pronounced, as if an anatomical diagram had been made flesh. He was powerfully, aggressively handsome, his new face all strong lines and focused intensity.
He looked at his own hands, turning them over. He flexed. A cable-like forearm muscle jumped. A slow, wondering smile spread across his new face.
“Oh,” he said, his voice deeper, a resonant bass that vibrated in the small room. “Oh, wow.”
He pushed himself to his feet with unsettling grace. He stood to his full, imposing height, seeming to fill the space, and looked at Jacob. His eyes were the same, but the gaze behind them was altered, lit with a new, predatory awareness.
He looked down at his own body, his hand running appreciatively over the dense shelf of his pectoral muscle, then lower, over the hard ridges of his stomach. He took his own substantial length in his hand, weighing it, a low chuckle rumbling in his chest.
“You,” Dave said, his new eyes locking onto Jacob’s. The awe was gone, replaced by a hot, possessive clarity. “You did this.”
He took a step forward. The floorboard creaked under the new, heavy weight of him.
Jacob could only stare, the last remnants of his own shame vaporized by sheer, incandescent terror. The fly on the sill. The fluid. The transmission.
It wasn't over.
It was spreading.
