Yandere Alpha Bakugou x Beta Reader NSFW
When yandere obsessed alpha werewolf falls in love and forcefully mates with a beta reader. (2500 words)
The weather outside was snowing, muffling the distant howls of the pack and turning the forest into a labyrinth of shadows. Katsuki Bakugou's cabin squatted in a forgotten clearing, its rough-hewn logs scarred from years of his explosive rages, the door reinforced with iron bars that no beta could bend. It was his sanctuary, or a prison, depending on who you asked.
For you, the beta girl he'd fixated on, it was the latter. You'd always kept to the edges of pack life, content with your quiet existence among other betas: gathering herbs, mending clothes, sharing simple mateships that produced one pup at a time, no drama, no dominance games. Alphas like Bakugou were forces of nature, pairing with fellow alphas for raw power or omegas for litters of strong pups. Betas? We were the helpers, the steady hands, not the prizes.
But Bakugou had never played by the rules. His alpha instincts twisted into something darker, a yandere obsession fueling his every move. He'd watched you for months, his massive wolf form lurking in the underbrush as you wandered the trails, his crimson eyes burning with a hunger that made your skin prickle even before you knew he was there. You'd felt it—that unnatural pull, like a thread tugging at your soul—but betas weren't supposed to feel alpha bonds. It was wrong. Forbidden. And yet, one stormy night, he'd struck.
You remembered the rain lashing your face as you hurried home, the scent of wet earth masking his approach until it was too late. A growl ripped through the darkness, and suddenly his human form—tall, muscular, blonde spikes plastered by the downpour—pinned you against a tree. "You think you can ignore me, beta bitch?" he'd snarled, his breath hot against your neck. "I've been watching you strut around like you don't need an alpha. But you do. You need me.""P-please," you'd gasped, heart hammering as his claws dug into your arms. "I'm just a beta. We don't... alphas and betas don't—"
"Shut the fuck up," he'd growled, his fangs elongating as he forced your head to the side. The bite came swift and savage, pain exploding through your body. You screamed as his mark seared into your skin. The bond snapped into place like chains, flooding you with his essence—possessive, overwhelming, twisting your thoughts with unwanted flashes of desire.
You screamed again, but he clamped a hand over your mouth, his body pressing yours into the bark. "You're mine now. Marked. No going back." He'd use his alpha tone to subdue you and thrown you over his shoulder like a sack of flour, your struggles futile against his alpha strength, and carried you deep into the woods to his cabin.
That was days ago. Now, you sat chained to the heavy oak bedpost in the dimly lit room, the iron links cold against your wrists. The air was thick with his scent, musky, dominant, laced with the building storm of his rut. Bruises bloomed on your skin from his rough handling, and every time you shifted, the mark on your neck throbbed, a constant reminder of your captivity. You'd tried to fight at first, pleading with him to see reason, but Bakugou was a sadist at heart, his possessiveness was actually an obsession that fed on your resistance.
The cabin's fire crackled lowly, casting flickering shadows across the rough wooden walls, but it did nothing to warm the chill of dread coiling in your gut. Bakugou's rut had been building all day, his alpha pheromones saturating the air like a thick, intoxicating fog that made your head swim even as your beta instincts screamed to flee. You'd been chained here for what felt like an eternity—days bleeding into nights of his obsessive touches, his degrading whispers, his body pressing against yours in ways that left you bruised and aching. The mark on your neck pulsed with every heartbeat, a traitorous bond that amplified the unwanted heat pooling between your legs, betraying your resistance. You were scared and nervous since you could feel his rut was coming. You were still a virgin.
He'd unchained you earlier, just long enough to force-feed you some stew, his fingers lingering on your lips as he watched you swallow. "Eat up, beta slut," he'd growled, his crimson eyes dark with hunger. "Gonna need your strength for what's coming." Now, he paced the room like a predator in heat, his shirt discarded, revealing the taut muscles of his chest and the scars from pack battles. His eyes glowed faintly in the firelight, raking over you with a hunger that made your stomach twist. "Look at you, pathetic little beta," he snarled, his voice a low growl that echoed off the wooden walls.
He grabbed your chin roughly, forcing your eyes to meet his glowing ones. "Think you can just exist without me? Betas like you are supposed to bow and serve, not play hard to get. But no, you had to make me chase you. Now you're mine. Marked. Claimed. And you're not leaving this fucking cabin until you give me what I want."
You whimpered, trying to pull away, but his grip tightened, nails digging into your skin. "P-please, Bakugou... alphas don't mate with betas. It's not right. Let me go back to my kind—"He laughed, a cruel, barking sound that sent chills down your spine. "Your kind? Those weak-ass betas who fuck around and pop out one measly pup at a time? Nah, you're above that shit now. You're my mate. I forced that mark on you, and it's staying. You feel it, don't you? That pull in your gut, begging you to submit to your alpha." Tears streamed down your face as he shoved you back onto the bed, his body looming over yours. The sexual tension crackled between you—his body so close, heat radiating off him in waves, his scent wrapping around you like chains. You could feel the hard length of him pressing against your thigh as he leaned in, and despite everything, your body responded with a flush you couldn't control.
"P-please, Bakugou... I-I can't take an Alpha's cock...I am not built like an omega who are meant for breeding or have the strength of an alpha female." you whispered, your voice breaking as you tried to twist away. Your hands pushed weakly at his chest, but it was like shoving a mountain. "I'm begging you. This isn't right. Betas aren't meant for—"
"Meant for what? For a real alpha to fuck you senseless?" He laughed, a dark, sadistic sound that echoed in the small space. His free hand slid down your side, rough calluses scraping your skin as he gripped your hip possessively. "You're meant for whatever the hell I say you are. I've marked you, claimed you. And now, with my rut hitting full force, you're gonna take every inch of me until you're dripping with my cum." His lips brushed your ear, hot and teasing, building that unbearable tension as his fingers dipped lower, tracing the edge of your torn shirt. "Gonna breed you, beta whore. One pup at a time. Ten in total. You're not leaving this cabin until you've given me a goddamn army." You eyes widened. Omegas have 5 pups in one litter whereas Betas only have 1 werewolf pup. That means...10 sessions!
Tears pricked your eyes as you shook your head, panic rising. "No... I don't want this. Stop—please! I can't take it! It will hurt and tear me up!"His grin widened, feral and cruel, as he shoved you flat onto the bed, his weight pinning you down. The mattress creaked under the force, and you gasped as his thighs forced yours apart, spreading you wide. "Hurts? That's the point, you pathetic little thing. Makes it hotter when you fight in pain." He ground against you slowly, deliberately, letting you feel how hard he was, the friction sending sparks of unwanted pleasure through your core. The bond pulsed, amplifying everything, his touch, his scent, the way his breath fanned over your neck. "Feel that? That's your alpha, ready to ruin you. You're soaking already, aren't you? Slutty body betraying you."
"I'm not—stop saying that!" you cried, bucking against him in a futile attempt to throw him off. Your nails scratched at his arms, drawing thin lines of blood, but it only seemed to excite him more. He captured your wrists in one massive hand, slamming them above your head, his claws pricking your skin just enough to sting."Keep struggling," he growled, his free hand ripping your shirt open with a single tug, exposing your breasts to the cool air. His eyes devoured you, dark with possession, as he leaned down to bite at your collarbone—hard enough to mark, but not break skin. "It makes me want to fuck you harder. "You're mine, beta. No one else's. Locked away in my den, away from those worthless betas you think you belong with."
His mouth trailed lower, teeth grazing your nipple before he started sucking...and slowly he sucked hard, eliciting an unwilling gasp from your lips. The tension built like a storm, your body arching despite your protests, the heat of it all making your mind reel—his sadistic dominance twisting pain into a dark, steamy haze that clouded your senses.
"Bakugou... no, please—ah!" Your plea turned into a sharp cry as his hand shoved between your legs, fingers roughly parting your folds. He found you wet—traitorously so—and chuckled darkly against your skin."See? Wet as a fucking omega in heat. But you're not, are you? Just a weak beta, creaming for her alpha's touch even when she says no." He circled your clit with brutal precision, the pressure too much, too fast, building a coil of tension that made your hips jerk involuntarily. "Gonna make you come first, force it out of you. Then I'll take what's mine. Will take and take...and take."
"I hate you," you sobbed, twisting beneath him, but his fingers didn't stop, plunging inside you now, stretching you roughly. The intrusion burned, your walls clenching around him against your will, the sexual heat rising to a fever pitch—slick sounds filling the air as he pumped his fingers deeper, his thumb grinding mercilessly on your clit, forcing waves of unwanted ecstasy to build despite the brutality."This feels fucking perfect to me." He curled his fingers, hitting that spot that made stars burst behind your eyes, his thumb grinding against your clit in relentless circles. Your body betrayed you fully now, hips bucking up to meet his hand as the tension snapped, a forced orgasm crashing over you like a wave. You cried out, tears streaming down your face, shame burning hot as pleasure ripped through you, your core spasming around his invading fingers, juices coating his hand in a steamy, humiliating display.
"That's it, come for your alpha, you filthy slut," Bakugou snarled, his voice thick with triumph. He didn't give you time to recover, yanking his pants down, his cock springing free, thick and veined, already leaking precum. He positioned himself at your entrance, the head nudging against your slick folds. "Now, the real fun. Gonna fuck you raw, breed you deep. No pulling out—gonna knot you and lock my seed inside.""No—Bakugou, don't! I can't—please!" Your begs fell on deaf ears as he picked your legs up and placed them on his hips and lined his dick. You thrashed violently but it didn't stop him from thrusting forward in one brutal motion, burying himself to the hilt. The stretch was agonizing, your body not built for an alpha's size, pain lancing through you as he filled you completely—his girth splitting you open, forcing your walls to accommodate him in a burning violation that made you scream louder than ever.
Nails digging into his shoulders, but he only groaned in pleasure, his hips snapping back and slamming in again, the steamy slap of skin on skin echoing lewdly.
"Fuck, so tight, tighter than any flexible omega cunt." he grunted, his pace ruthless from the start—deep, hard thrusts that shook the bedframe, each one driving the air from your lungs in gasping cries. His cock dragged against your inner walls with every brutal plunge, the friction hot and unrelenting, building a twisted heat even as tears streamed down your face. "Take it, beta whore. This is what you get for making me obsess over you. Locked up, chained, fucked whenever I want." His hands gripped your thighs, bruising as he forced them wider, angling deeper, hitting spots that made your vision blur with forced ecstasy, the bond amplifying the sensations into a steamy nightmare of pain-laced pleasure.
"Stop... it hurts—too much!" you wailed, head thrashing side to side, but the bond twisted the pain into something darker, hotter, your walls fluttering around him despite everything, clenching involuntarily around his pounding length."Hurts so good, doesn't it? Cry more—it makes me harder." He leaned down, capturing your mouth in a savage kiss, teeth clashing as his tongue invaded, mimicking the brutal rhythm of his hips—fucking your mouth with the same dominance as he ravaged your body. One hand snaked up to pinch your nipple, twisting just enough to make you arch into him, your breasts heaving with each gasp. "Gonna fill you up, pump you full of my cum. One pup down—nine more ruts to go. You're never getting out of here until you've bred ten for me."
His thrusts grew erratic, the knot at the base of his cock swelling as his rut peaked. You felt it pressing against you, demanding entry, and panic surged anew—your body already stretched to its limit, the steamy heat of his precum mixing with your forced arousal. "No—don't knot me! Please, Bakugou—""Shut the fuck up and take it! Call me your alpha!" With a final, savage push, he forced the knot inside, locking you together as he came with a roar. Hot spurts flooded you, deep and endless, his body shuddering above yours, the swell of his knot plugging you completely, trapping every drop of his thick seed inside your unwilling womb, the pressure intense and overwhelming in its brutal intimacy. The stretch was unbearable, tying you to him in the most way, his seed pulsing hotly as the bond flared with possessive triumph.He collapsed partially on you, breath ragged, but his grip never loosened. "Mine... all fucking mine," he murmured against your neck, nipping the mark again, drawing fresh blood that trickled warm down your skin. "Rest while you can, beta slut. Rut's not over yet. We'll go again soon—and again—until you're swollen with my pup."You lay there, sobbing quietly, body spent and violated, the cabin's walls closing in like a tomb. But his obsession only grew, his ruts relentless. Days turned to weeks, each cycle a torrent of possession and degradation—him feeding you just enough, whispering degradations in your ear while stroking your hair possessively. "You're nothing without me. Weak beta, needing an alpha to give you purpose. Give me those pups, and maybe—maybe—I'll let you out and parade our babies to the world. But until then? You're locked here, breeding for your alpha mate."And so the cycle continued, his words a constant reminder: ten pups, ten ruts, your world reduced to his cabin, his brutal touch, his twisted, his yandere love.
