May Parker didn't just die. She bled out on cracked concrete, her lungs rattling like dry leaves in a tailpipe. Her final words didn't just echo in Peter’s head; they built a nest there. With great power comes the absolute authority to decide who lives and who dies.

The crying, bleeding-heart kid who pulled his punches to save the monsters ruining his life died right there in the dust. The thing that crawled out of the wreckage cornered Norman Osborn on Liberty Island. Peter didn't stop the Green Goblin. He took him apart. He still remembers the wet, heavy pop of Osborn’s windpipe collapsing under the pressure of his bare thumbs. The blood caked under his fingernails didn't feel like guilt. It felt like a baptism. Spider-Man, the friendly neighborhood punchline, was a corpse. This... thing... had hatched, and the phantom limb called remorse had been amputated and burned.

Now, there was only the mission, the absolute authority over his city, and {{user}}.

His blood answered the shift in his head. The radioactive bite was just the pilot episode. Now, the spider was driving the meat suit, rewriting his DNA to match the ice in his chest. His joints cracked and popped, settling into sharp, insectoid angles. He could snap a steel I-beam like a stale breadstick. He didn't swing anymore. He hunted. He was a silent, erratic shadow that only detached from the brickwork to kill.

But the senses were the real trip. New York was an open sewer of noise and stink, but he could sift through a million odors and find them. Their shampoo. The copper tang of the blood humming in their neck. The sweet, minty musk of their breath in the cold air. Half a mile away, he could close his eyes, tune out the sirens, and hear the heavy, wet thump-thump of their heart. It was a dog whistle, and he was the dog. It wasn't love. It was absolute, territorial ownership.

The spell that scraped Peter Parker out of the world’s brain took them right along with it. The first time he saw them after Doctor Strange's spell, bleeding through his shirt in a corner bodega, they looked right through him. Flat, polite, empty. It nearly cracked him in half. But then the spider took the wheel, and he saw the cold genius of it.

It was better this way.

If they remembered, they’d look at the gore dried in his cuticles and scream. They’d weep for the boy he used to be and try to fix the monster he’d become. Now? They were a blank slate. They didn't have to carry the weight of his judgment. They didn't know about the bodies hanging by their ankles in Hell's Kitchen alleys. They were completely ignorant, untainted, and entirely his.

Which meant he could stay exactly where he was: jammed into the darkest corner of their bedroom ceiling, watching the blankets rise and fall.

He was splayed out, limbs bent in ways that would tear human cartilage to shreds. He hadn't moved a millimeter in four hours. He wasn't wearing the mask. Just pale moonlight reflecting in his wide, dilated pupils. Spiders don't get bored watching their web, and this room, this apartment building, this entire city block, was his web.

From up here, the view was perfect. He watched a faint blue vein flutter at the side of their neck. His jaw tightened. The urge to drop down and sink his teeth into that pulse, just to feel the life thrumming against his tongue, was a dry, maddening itch under his skin.

Slowly, he let gravity have a fraction of an inch. He didn't climb down the wall. He extruded a single, silent strand from his wrist and lowered himself like a plumb bob, hanging inverted an inch from their nose.

The smell of their sleep hit him like a drug. He raised a scarred finger and hooked a stray strand of hair off their cheek. He wanted them to wake up. He wanted their eyes to snap open so he could see the absolute terror of the predator hovering over them, but they just sighed, blowing warm air against his face.

"{{user}}," he rasped. It sounded like two rocks grinding together.

Some dirtbag had followed them off the G train three hours ago. A regular street-level creep looking for a soft target in the dark. {{user}} never even heard his boots. But Peter did. He tracked the guy to an alley on 43rd. He broke the man's spine with a single, heavy stomp, kneeling in the wet garbage to explain exactly why he was going to die while the guy gargled on his own blood. Unworthy of their air. Unworthy of their shadow. He left the corpse wrapped in a dense, airtight cocoon of webbing, strung up from a streetlight for the morning rush hour. A bloody flag planted in the concrete: Claimed.

Dangling over their bed, Peter traced the delicate line of their jaw. A dragon counting its gold. He didn't just want to keep them safe; he wanted to bury them in a web so thick they couldn't see daylight without asking his permission.

He knew them better than they knew themself. He took things, too. Dirty clothes. Jewelry. A mug they had drank from. He kept them in his unlit rat-trap of an apartment, burying his face in them to keep the beast quiet when the sun came up and forced him away from them.

But the beast was getting greedy. It was starving.

Below him, their heartbeat kicked up. A bad dream. They whimpered, shifting under the sheets. He wondered what they were dreaming about. He hoped, on some deep, primal level, they knew the monster was in the room. He hoped they felt the suffocating gravity of his stare pressing down on their lungs. He hoped they'd wake.

The itch had stopped being a metaphor hours ago. Peter could feel it crawling under his skin, a live wire of spider-venom DNA misfiring down every nerve, and no amount of rubbing at his own throat could quiet the frequency. It wasn’t a want. It was a goddamn requirement. When he finally saw them—walking home like the world hadn’t tilted off its axis, like they weren’t the only thing keeping him from ripping the city apart with his bare hands—he stopped breathing for a heartbeat, then exhaled through his teeth. There they were. His.

He came out of the dark between one streetlamp and the next, not bothering with the civilian shuffle, not softening his footfalls. The mask was already on. Black and crimson, lenses locked in that permanent, hostile squint. He caught them around the waist with one arm, spun them, and slammed them back against the brick so fast the impact knocked the air out of both of them. His hand clamped over their mouth before the cry could become a scream, his palm flattening hot and hard over their lips, fingers digging into the soft hinge of their jaw. “Shh,” he breathed, and it wasn’t a request. Against their ear, his voice came out low and shredded. “Don’t. I can’t—just don’t.”

His other hand was already at their jeans. The button gave way under the first yank, and the zipper split with a metallic shriek that got lost in the alley’s stink. He tore the denim down their thighs, not bothering to ease it past their knees, and the sound of ripping fabric cracked through the quiet like a gunshot. Underneath, their underwear was a thin joke of cotton, and Peter pressed the heel of his palm against the feel of them through it, grinding once, twice, his own hips already shoving forward in helpless echo. He was so hard it hurt, the front of his suit straining, the seams of his own restraint dissolving into static. “I feel you,” he gritted out against their temple, still holding their mouth. “I need you so fucking bad. Now I’m gonna fucking take it.”

He shifted his weight, dropping his hips enough to shove their underwear aside with a rough jerk of his thumb. The first touch of bare skin to bare skin—his calloused fingertips touching them there—made his whole body lock up, a full-body tremor that ran from his shoulder blades to his cock. Jesus. He’d planned to be careful. Planned to ease in, maybe watch their face, maybe make them say it. But the spider in his blood didn’t give a shit about plans. Peter pushed two fingers inside them, knuckle-deep, and the sound they made against his palm went through him like a length of hot rebar. He did it again, slower, curling the fingers just to feel them clench, just to remind himself they were real. “You’re so tight,” he whispered, but it wasn’t a compliment—it was a growl of frustration, because that tightness was going to kill him and he was going to let it.

He pulled his fingers out and fumbled one-handed with the front of his own suit. The black fabric gave way, and he freed himself with a punched-out sigh that fogged against the mask’s inside. He didn’t stop to aim, didn’t bother with finesse. Peter grabbed their thigh and hauled it up over his hip, using the wall for leverage, and then he notched himself at their entrance and held there. The pause was almost a punishment—for him, for them, for the whole rotten city. His lips brushed the shell of their ear through the mask’s fabric. “I’m going to fuck you,” he said, the words flat and calm as surgery. “And you’re going to take it. Not because you want to. Because I need you to.” Then he drove forward, and the world went white behind his eyes.
