Chapter 2: Knotting at the Threshold
Izuku didn’t pull away. He held her tighter against the doorframe, his body shuddering as he spilled inside her with a choked, guttural cry. The thick, hot pulses of his release seemed to go on forever, marking her, claiming her in the most primal way possible. Bakugou’s growl deepened into a continuous, vibrating snarl that made the splintered wood tremble.
“You think this makes her yours?” Bakugou’s voice was a razor dragged over stone. He was still in his hybrid form, a monument of contained fury in the hallway. His eyes, burning like hellfire, were locked on the place where Izuku was still joined to her, his knot swelling to keep them locked together.
Izuku’s breath was ragged against Sophia’s neck. “She’s not a thing to be owned, Kacchan.”
“Everything in these woods is mine.” Bakugou took a step closer, the scent of his rage—ozone and hot iron—swamping the air. “Including you. And now you’ve put your scent all over what I’ve claimed.”
Sophia found her voice, raw but steady. “You don’t get to claim people.” Bakugou’s gaze snapped to hers, and the raw possession in it stole her breath. “I do,” he said, simple and absolute as a law of nature. He reached out, one claw-tipped finger tracing a line through the sweat on her collarbone, then lower, through the tear in her nightgown, brushing the swell of her breast. “She’s soft. And she smells like us now. Like pack.”
Izuku tried to shift, to shield her, but his knot held them fast. “Don’t.”
Bakugou ignored him, his finger hooking into the torn fabric and pulling, rending it further until she was fully exposed to his scorching gaze. “Mine,” he breathed, the word a dark promise. Then his other hand wrapped around the back of Izuku’s neck, not to pull him away, but to hold him there. “Finish it. Let her feel what we are.”
He didn't wait for Izuku's consent. Bakugou’s other hand, broad and rough, shoved Izuku's hips forward, grinding him deeper into Sophia as his knot pulsed the last of his spend. "Feel that?" Bakugou growled against Izuku's ear, his own arousal a hard, insistent pressure against the rabbit's back. "You're just the first course."
Sophia gasped, overstimulated and pinned, her fingers whitening where they gripped Izuku's shoulders. Bakugou’s teeth grazed Izuku's throat, a warning bite, before he looked down at her with those burning eyes. "My turn."
He yanked Izuku back by the hair, the sudden separation wringing a sharp cry from them both. Before she could stumble, Bakugou spun her around to face the shattered doorframe, her back to his chest. His arm banded across her collarbone like iron, the fresh linen of his bandage rough against her skin. "Watch him," he commanded, his voice a dark rumble through her bones.
Izuku slumped against the opposite wall, chest heaving, his expression a mix of sated exhaustion and sharp anxiety. Bakugou’s free hand pawed at the remains of her nightgown, then shoved his own pants down. He was thicker than Izuku, heavier, and he didn't bother with gentle pressure. He guided himself to her soaked entrance with a brutal, impatient grunt.
He slammed into her with one vicious thrust, tearing a ragged scream from her throat. "Mine," he snarled into her curls, his hips setting a punishing, possessive rhythm against her ass. Each drive punched the air from her lungs, a raw claiming that obliterated every thought.
The stretch and burn of him was a brutal counterpoint to Izuku’s frantic pace, a deep, consuming fullness that left her gasping. "You take it so well," Bakugou grunted, his breath scorching her ear, his hips never slowing. Izuku watched from the floor, his green eyes dark with a mix of guilt and arousal.
"Kacchan, you're hurting her," he whispered, but his voice lacked conviction. "She likes it," Bakugou growled, one hand snaking down to cup her breast, his fingers pinching her nipple hard. Sophia cried out, the pain sharp and bright, mingling with the overwhelming pleasure coiling in her gut.
Her world narrowed to the slap of skin, the smell of sex and sweat, and the relentless pressure inside her. "Come on, little human," he taunted, his voice a rough vibration against her back. "Show me you're mine."
The command sparked something in her—a defiance that cut through the haze. She twisted her head, her mouth finding the corded muscle of his neck where it met his shoulder. Without hesitation, she sank her teeth into his skin, hard enough to taste copper.
Bakugou froze, a shocked, guttural sound ripped from his throat. His grip on her tightened almost painfully, but his hips stuttered to a halt. "You bitch," he breathed, but there was no anger, only a stark, surprised reverence.
He pulled back slightly to look at her, his crimson eyes wide with something like approval. Izuku stared, his mouth agape, as a slow trickle of blood welled from the bite mark. Sophia released her jaw, panting, the metallic taste of his blood on her tongue.
"Marked me back, did you?" Bakugou said, a rough laugh escaping him. He resumed his thrusts, but slower now, more deliberate, as if savoring the new connection. His hand came up to touch the wound, his fingers coming away smeared red, and he smiled—a wild, possessive thing.
That smile unlocked something between them, a circuit snapping closed deep in his chest. His next thrust wasn't about possession anymore; it was a frantic search for connection, his rhythm becoming ragged and deep. "Fuck, what is this?" he grunted, his forehead dropping to her shoulder as a foreign warmth flooded his veins.
It wasn't just warmth. It was a torrent of feeling that wasn't his own. The sharp, sweet ache of her overstimulated body echoed in his nerves. The dizzying thrum of Izuku’s watchful anxiety pricked at the edge of his mind. A psychic channel, raw and screaming, blasted open between them.
Sophia felt it too. A second presence, fierce and molten, poured into her mind alongside the brutal fullness of his cock. She could feel his shock, the crumbling of his solitary fury, the terrifying need beneath it. "Bakugou—" she gasped, her voice breaking.
"Katsuki," he corrected harshly, the name a surrender as he fucked into her with renewed, desperate intensity. "Say it."
"Katsuki!" The name was torn from her as she came, her inner muscles clamping around him in violent waves that echoed through the newly-formed link. He roared, his own climax ripped from him, his seed pumping into her in thick, claiming spurts that seemed to seal the bond.
Izuku scrambled forward, drawn by the palpable shift in the air. The moment his hand touched Sophia’s outstretched fingers, the circuit tripled. The pack bond exploded into full, devastating color. Katsuki’s possessive fire, Sophia’s accepting warmth, and Izuku’s fierce devotion crashed together into a single, howling truth. They were one.
The psychic feedback loop was a live wire, sizzling and popping behind their eyes. Katsuki’s final, pulsing release wasn’t just a physical sensation; it flooded Sophia’s mind with the blinding-white heat of his surrender, a searing counterpoint to the aching, sweet fullness in her cunt. Izuku’s sharp gasp wasn’t just sound; it was a jolt of shared astonishment that traveled the connection, a third heartbeat thrumming between them.
Katsuki slumped against her, his weight pressing her into the splintered wood, his breathing ragged gusts in her ear. "The fuck did you do?" he mumbled, but the accusation was hollow, drowned by the unfamiliar torrent of her satisfaction echoing in his skull. His hand, still smeared with her saliva and his blood, slid possessively over her stomach.
Izuku crawled closer, his long fingers trembling as they touched Katsuki’s arm, completing the circuit. The bond surged, a three-way street of sensation. Sophia felt the lingering, pleasant throb in Izuku’s spent cock. Katsuki tasted the salt of her sweat on his own tongue. "It’s the moonflowers," Izuku whispered, awed and terrified. "Her garden... it’s always been a beacon."
"Shut up, nerd," Katsuki growled, but he didn’t let go. He turned his head, his nose burying in Sophia’s tangled curls, inhaling deeply. Now her scent was irrevocably woven with his own, with Izuku’s, a permanent mark in his senses. The bond wasn't a choice; it was a fact, carved into their very neurons.
He shifted, his softened cock slipping from her with a wet, intimate sound that echoed in the silent room. The loss of the physical connection made the psychic one scream louder. Sophia whimpered, feeling suddenly hollow. In answer, Katsuki spun her around, his movements less violent now, more deliberate. He looked down at her, his crimson eyes no longer just furious. They were bewildered. Owned.
"Look at me," he commanded, his voice rough. She did, her dark eyes wide, reflecting his own conflicted face. He kissed her then, a brutal, claiming press of lips that was all teeth and shared breath. It was a seal. When he broke it, he turned his head toward Izuku, who was watching, his green eyes luminous. "You too. Now."
It wasn't a request. The pull was magnetic, undeniable. Izuku rose to his knees, and Katsuki’s hand fisted in his hair, dragging him into the kiss. Sophia watched, a fresh, shocking bolt of heat curling in her gut as Katsuki dominated Izuku’s mouth with the same fierce ownership. The bond sang, pleasure tripling and reverberating. This was the solidification. Not just a claim, but a fusion. They were a knot, tangled and permanent, and the woods outside would never be just woods again.
The three of them collapsed in a heap of tangled limbs and spent breath onto the worn floorboards, the psychic link settling into a low, humming current. Sophia’s mind was a shared space, crowded with the echo of Katsuki’s relentless possession and the softer brush of Izuku’s wonder. Dawn’s first grey light seeped through the round window, painting their skin in pallid shades.
It revealed the bite mark on Katsuki’s shoulder, already a darkening bruise, and the sticky, cooling evidence of their joining smeared across Sophia’s inner thighs. “Fuck,” Katsuki muttered, the word lacking its usual heat, his fingers tracing the wound she’d given him. Izuku nuzzled into the crook of Sophia’s neck, his long ear tickling her jaw. “The bond… it’s not fading.”
“It’s permanent,” Katsuki said, not as a growl, but a raw statement of fact. He shifted, his body a heavy, warm line against her back. “Can’t shut it out.” Sophia felt it—a low-grade awareness of their presence in her skull, like a second pulse. “What does it mean?” she asked, her voice husky.
“It means you’re pack,” Izuku whispered, his hand finding hers. “For real.” Katsuki’s silence was agreement. He sat up suddenly, the movement jarring. “We stink,” he announced, his nose wrinkling at the combined scents of sex, blood, and shattered pine. “And I’m starving.” He stood, his bandaged leg bearing his weight without a flinch, and looked down at the two of them. A possessive satisfaction flared through the bond, bright and hot. “Get up. Clean up. I’ll fix the damn door.”
He stalked out, leaving them in the sudden, cool silence of the ruined room. Izuku helped Sophia up, his touch gentle on her sticky skin. “He’s really going to fix it,” he said, a quiet wonder in his voice.
Through the shattered opening, the first true rays of dawn speared the gloom. They fell across the trampled herb garden outside the kitchen window. And there, nestled among the crushed sage and thyme, a cluster of closed, silver-white buds began to glow with an inner light. Sophia gasped, a sharp intake of breath that echoed in the new quiet.
The moonflowers, impervious to the night’s chaos, unfurled. Their petals opened with a soft, audible sigh, releasing a scent that was cold starlight and deep, damp earth. It washed into the cottage, clean and potent, mingling with the musk of sex and blood. Izuku’s ears shot straight up, trembling. “They’ve never bloomed at dawn,” he whispered.
From the porch, the sound of Bakugou’s hammering ceased. A thick, loaded silence followed. Then his shadow filled the doorway again, his form blocking the new light. He stared past them, out the window, at the luminous flowers. His crimson eyes widened, just for a second, before narrowing. “Told you,” he grunted, his voice oddly subdued. “They’re a beacon.”
The scent wrapped around them, sharpening the hum of the fresh bond in their minds. It didn’t just smell of the woods; it smelled of them, of the tangled, raw connection now pulsing between their three hearts. Sophia understood. The flowers weren’t just blooming. They were celebrating. They were marking territory. Bakugou met her gaze, and for the first time, there was no fight in his eyes, only a grim, awestruck acknowledgement. The game was over. The woods knew.
