Chapter 4: The Extraction
The cabin’s silence was a fragile thing. It strained under the weight of Kael’s breathing—a wet, ragged sound that echoed in the vaulted space. Natasha had cleaned her as best she could, but the chemical stink of the lab still clung to her fur, underlying the scent of dried blood and fear-sweat. The serum-induced swelling had receded slightly, leaving Kael a hulking, seven-foot testament of brutalized muscle. She lay on the rug before the cold fireplace, twitching in her sleep, a low whine bubbling in her throat.
Natasha watched from the worn armchair, a blanket around her shoulders, a stark pistol in her lap. Steve and Tony were gone, their concern a palpable, awkward cloud she’d dismissed with a single, flat look. This was her mess. Her weapon. Her creature.
Kael’s eyes snapped open. Not the slow bleariness of waking, but the instantaneous, hyper-aware ignition of a predator sensing threat. She rolled onto her hands and knees, a move that should have been clumsy for her size but was terrifyingly fluid. Her amber eyes, pupils blown wide, locked onto Natasha.
“Kaelen,” Natasha said, her voice refusing to waver. “Look at me.”
Kael’s nostrils flared. She took a shuddering inhale, parsing the room’s chemistry: woodsmoke, pine, her own musk, and underneath it all, the iron-and-honey core of Natasha. The wild panic in her gaze fractured, replaced by a confused, aching recognition. A shiver wracked her frame, starting at the massive shoulders and running down the knotted ridge of her spine.
“It’s over,” Natasha lied smoothly. She placed the pistol on the floor beside the chair and stood, letting the blanket fall. She wore only a thin tank top and shorts. Submission, but on her terms. A calculated vulnerability. “You’re home. You’re with me.”
Kael crawled forward. Not the charge of a beast, but the desperate, stalking approach of a wounded animal seeking its only source of solace. She stopped at Natasha’s feet, her head lowered. A fat drop of viscous, clear fluid dripped from the tip of her cock onto the rug. It was obscenely large, even for her, still semi-erect and heavy with the serum’s lingering poison.
Natasha didn’t flinch. She reached down, her fingers threading through the grime-matted fur at Kael’s temples. “They pumped you full of poison,” she murmured, scratching gently. “Made you bigger. Meaner. But you knew me. You came back.”
A broken rumble started in Kael’s chest, part growl, part sob. She pressed her hot forehead against Natasha’s stomach, nuzzling, inhaling her in deep, desperate draughts. Her hands came up slowly, claws retracted, to grip Natasha’s hips. The touch was possessive, trembling.
“I need to feel you,” Kael rasped, her voice shredded from screaming. “Need to feel… real. Not what they made me.”
Natasha understood. The serum was a fire in her veins, a chaos in her cells. She needed an anchor. A familiar, brutal truth. And truth, between them, had always been written in sweat and strain.
“Then take what you need,” Natasha said, her own pulse kicking hard. She tugged Kael’s head back, forcing those wild eyes to meet hers. “But you come to me. Not the beast they created. You.”
She stepped back, peeling off her tank top, then her shorts. The cool air raised goosebumps on her skin. She turned and walked to the massive four-poster bed, climbing onto the rumpled sheets. She got on her hands and knees, presenting herself—an offer and a command in one silent, loaded gesture.
Kael was on her in an instant. Not with the tender slowness of the morning, but with a single-minded, frantic urgency. Her weight settled over Natasha, a furnace of muscle and heat. One massive hand clamped on Natasha’s hip, the other fist closed in her auburn hair, not pulling, just holding, grounding.
Natasha felt the broad, slick head of Kael’s cock nudge against her entrance. It was hotter than normal, the skin tight and almost feverish. The sheer girth was staggering, a challenge that made her cunt ache in memory and anticipation. “Do it,” she hissed, pushing back. “Fuck their poison out. Fuck me back into your head.”
Kael drove forward.
The stretch was instantaneous, brutal, and breathtaking. Natasha cried out, her vision whitening at the edges as she was penetrated, filled beyond reason. Kael buried herself to the root in one relentless thrust, her hips flush against Natasha’s ass. There was no tenderness, no rhythm. Just possession. An act of reclamation.
“Oh, god, yes,” Natasha gasped, her voice muffled by the sheets. “That’s it. That’s your cock. Not theirs. Yours.” She clenched around the monstrous invasion, and Kael roared, the sound shaking the window panes.
Then Kael began to move. Short, savage pistons of her hips, withdrawing only a few inches before slamming home again. Each impact jolted Natasha forward, a brutal, punctuating rhythm. The wet slap of flesh was loud, animalistic. The bedframe groaned in protest.
“Harder,” Natasha demanded, pushing back against each thrust, taking control by demanding more. “You think this is all you’ve got? After what they did to you? Fuck me like you mean it, Kaelen! Fuck me like you’re fucking killing their ghosts!”
The taunt worked. A snarl tore from Kael’s throat, and her pace became an outright hammering. Her fingers dug into Natasha’s hip hard enough to bruise. Her other hand released Natasha’s hair and braced against the headboard for leverage, giving her deeper, harder angle. Natasha could feel every ridge, every vein of the enormous cock shredding her senses, touching her cervix with a punishing intimacy.
The violence of it was a purge. Kael was exorcising the lab, the straps, the needles, the cold, impersonal violation. Replacing it with this: a voluntary, sweat-slicked, grunting violation by the only person whose touch she craved. Her thrusts were becoming ragged, losing coordination, devolving into a primal need to spill, to mark, to connect.
“Where do you belong?” Natasha grunted, her own climax coiling tight, sparked by the sheer, overwhelming fullness.
“Here,” Kael gasped, her voice breaking. “With you. In you.”
“Then prove it. Fill me up. Breed me. Make it so I can’t forget who owns this cunt.”
With a final, wounded howl, Kael jammed herself in as deep as she could go and came. Natasha felt the hot, frantic pulse of it, a flood that seemed endless, spilling deep into her womb. The sensation triggered her own orgasm, a sharp, convulsive wave that clenched around the throbbing cock, milking it, demanding every last drop.
Kael collapsed atop her, a dead weight of shuddering muscle and spent rage. Her breath sobbed against Natasha’s neck. Natasha, crushed beneath her, endured it. She turned her head, her lips finding the shell of Kael’s sweat-salted ear.
“You’re back,” she whispered, her own body screaming in protest beneath the weight. “You’re mine.”
They lay there for a long time, until Kael’s breathing evened into sleep. Eventually, with immense effort, Natasha slid out from under her. Kael didn’t stir, a boneless heap of exhausted beast. Natasha stood on trembling legs, feeling the slow, hot leak of Kael’s spend trickle down her thigh. She walked to the bathroom, moving stiffly.
In the mirror, she saw the fresh bruises already blooming on her hips, the red scratches on her back. She ran a hand over her abdomen, a calculated thought cutting through the post-coital haze. The serum. It was in Kael’s system. In her seed. What would it do?
She rinsed her face with cold water. The questions, the repercussions, they were for tomorrow. HYDRA had dared to touch what was hers. They had seen her weapon unveiled. They would have theories, data, ambitions.
A faint, ice-cold smile touched her lips in the glass. Let them have their data. Let them come.
She had a warwolf to tend. And a war to plan.
