Kamada Tanjiro

Let’s Begin!

 

~~~~

The village of Higashiyama burned under the shadow of the colossal intruder. Roofs collapsed like paper under the thunder of her tail, wooden beams splintering as the massive, dark-skinned figure strode through the streets. Gojira towered over the panicked villagers. Gojira’s muscular frame glistening with sweat and debris, obsidian-black hair whipping wildly around her snarling face. One golden eye glowed with feral amusement, the other winked shut in mockery. Her enormous breasts bounced heavily with every step, dark nipples stiff and leaking thin trails of slick. Between her powerful thighs swung the impossible monstrosity: a 19-inch cock, veined and throbbing, thicker than a man’s forearm, its swollen head already drooling precum. Below it hung two melon-sized balls, heavy and swaying like pendulums of pure dominance. A long, scaled charcoal black tail lashed behind her, smashing carts and scattering screaming civilians.

She wasn’t here to conquer. She was bored. And then she smelled him.

Tanjiro Kamado burst from the treeline, sword drawn, the black blade of Nichirin gleaming in the firelight. His modified Demon Slayer uniform clung to his femboy body like a second skin: cropped haori exposing the smooth, toned expanse of his midriff, the white belt cinched tight around his narrow waist, the green-and-black checkered pants hugging thick, plush thighs and an ass so fat and round it jiggled with every hurried step. Platform geta clicked against the dirt. His short, spiky maroon hair framed a flushed, pretty face—large purple eyes wide with determination, soft cheeks already pink. At nineteen, he looked far too delicate for a slayer, all soft curves and feminine allure hidden beneath the uniform.

“Demon!” Tanjiro shouted, voice steady despite the chaos. “Your rampage ends here! I am Tanjiro Kamado of the Demon Slayer Corps. Prepare to—”

He froze mid-sentence.

Gojira had stopped. Her golden eye raked over him slowly, hungrily. A low, rumbling purr rolled from her throat as she licked her sharp teeth. “Well, well…look at this tasty little morsel. Those hips…that fat ass bouncing in those silly little shorts…mmm, and that pretty mouth just begging to be stuffed. You’re no demon slayer, boy. You’re a walking fucktoy. Come here, cutie. Let Mama Gojira break you in.”

Tanjiro’s face burned crimson. His sword trembled for half a second. “Wh-What?! I—I’m a man! A warrior! Your words won’t distract me!” He gripped the hilt tighter, stance firm. “Prepare to die, monster!”

Gojira simply smirked, fangs flashing. One clawed hand lazily stroked the underside of her monstrous cock, making it twitch and slap wetly against her abs. “Cute. Real cute.”

The next instant was a blur.

Her tail whipped around like a living whip, coiling around Tanjiro’s waist and yanking him off his feet before he could even swing. His sword clattered uselessly to the ground. Clothes shredded under her claws! Hair, shorts, checkered leggings ripped away in seconds until the femboy slayer was completely naked, smooth pale skin exposed, his own modest little cock already half-hard against his will. She slammed him against the nearest intact wall of a ruined house, the impact knocking the breath from his lungs.

Now he sat slumped against the cool stone, legs splayed wide, wrists pinned together above his head in one of Gojira’s massive hands. Her towering body loomed over him, breasts swaying inches from his face, her 19-inch futanari cock—dark, veined, and already glistening pressed right against his trembling lips.

“Open wide, little cocksleeve,” Gojira growled, voice dripping with mocking lust. “Time to teach a pretty boy his real purpose.”

Tanjiro’s eyes widened in pure shock. ‘S-She’s too big! There’s no way that thing fits in my mouth! I’m a man… a Demon Slayer… I should be disgusted, I should be fighting-‘

Gojira didn’t wait. She thrust forward, the fat, leaking head forcing past his lips and straight down his throat in one brutal slam. Balls-deep. His throat bulged obscenely around the impossible girth, the outline of her cockhead visible all the way down his neck. Melon-sized balls slapped wetly against his chin with a heavy thwack, smearing precum across his soft cheeks.

“Fuuuuck yes!” Gojira groaned, head tilting back in ecstasy. Her free hand gripped one of her own massive tits, squeezing hard enough to send milk-white droplets spraying. “Look at that~! Your throat’s sucking me in like it was made for this! So tight, so hot, so fucking perfect. You’re nothing but a warm, wet cocksleeve now, Tanjiro. My personal little throat-pussy~!”

She pulled back just enough for him to gag violently—thick ropes of saliva and precum spilling from the corners of his stretched lips—then slammed forward again, hips rolling with savage power.

GLUCK! GLUCK! GLUCK!

The wet, obscene sounds echoed off the ruined walls as she face-fucked him without mercy, balls slapping his chin in a relentless rhythm.

Tanjiro’s mind reeled. ‘How…how is she doing this?! It’s too deep—too thick—I can’t breathe! I’m a man…I’m supposed to hate this…supposed to be revolted by a woman’s cock stretching my throat…but—gods—why does it feel so good? My body’s burning… my own cock is twitching…no, stop thinking that!’

Tears streamed down his flushed cheeks. His throat convulsed around her girth, muscles milking her involuntarily. Every brutal thrust sent shockwaves through his body; his plump ass clenched against the wall, his small cock now fully hard and leaking pathetically onto his stomach.

Gojira laughed, low and cruel, leaning down so her hot breath washed over his face. “Aww, listen to you choking, baby. Gag for me~. Yeah, just like that. Your pretty purple eyes are rolling back already. Look at those fat tits of yours jiggling—no, wait, those are mine~.” She released her own breast just long enough to slap one of his perky pecs, then pinched his nipple hard. “But you’re the one with the real fuckable body. That soft belly, those thick thighs…and this throat? Holy shit, it’s gripping me like a virgin pussy. You were made to swallow monster cock, weren’t you, you pathetic little femboy slut?”

She slammed in again, holding balls-deep, grinding her heavy sack against his chin while his nose pressed into the musky base of her shaft. His throat spasmed wildly, desperate for air, but she only purred louder.

“Feel that? Every inch of my 19-inch girl-dick owning your face. Those melon balls churning cum just for you. I’m gonna flood your stomach until it swells like you’re pregnant with my load. And you’re gonna love it~! Just look at your tiny boy-clit dripping all over yourself. Disgusted? Bullshit. You’re soaked for it.”

Tanjiro’s thoughts fractured into desperate, shameful heat. ‘She’s right…I can feel it pulsing in my throat… so hot…so thick…I should push her away…I’m a slayer…but my body’s betraying me…every thrust makes me throb…I’m getting off on being used like this…no—no—yes!!’

Gojira picked up speed, hips pistoning like a machine.

SCHLORP! SCHLORP! SCHLORP!

Saliva cascaded down his chin, dripping onto his heaving chest. Her tail coiled around his waist again, lifting his ass slightly so she could angle deeper, the bulge in his throat visibly sliding up and down with every savage stroke.

“Keep sucking, bitch! Milk Mama’s cock with that greedy throat! You’re not a demon slayer anymore! You’re Gojira’s personal onahole. Say it with your eyes, pretty boy. Tell me how much you love choking on woman-meat!”

Tanjiro could only gag and whimper around the monstrous invasion, his vision blurring with tears and overwhelming pleasure. His body surrendered completely—limp, pinned, throat bulging and convulsing; while Gojira laughed and fucked his face harder, breasts bouncing, tail thrashing, golden eye blazing with triumphant lust.

The village burned around them, but neither cared. All that mattered was the wet, rhythmic destruction of Tanjiro’s throat and the delicious, humiliating sounds of a once-proud slayer reduced to a drooling, cock-drunk cocksleeve.

Gojira’s golden eye rolled back for a split second as another violent gag rippled around her throbbing 19-inch monstrosity, Tanjiro’s throat convulsing like a living sleeve desperate to milk her. But the heat boiling in her core was too savage now. With a wet, obscene SCHLORP, she ripped her cock free in one brutal yank. Thick ropes of saliva and precum exploded from Tanjiro’s ruined mouth, splattering across his heaving chest and dripping in heavy strands from his chin. The femboy slayer slumped against the wall, coughing and gasping, his pretty purple eyes crossed, tongue already starting to loll stupidly as his brain tried to reboot.

The massive futanari didn’t give him a second to recover.

A deep, animal growl rumbled from Gojira’s chest, vibrating through her entire muscular frame. Her dark, sweat-glistened breasts heaved, nipples stiff and leaking. That impossible cock still rock-hard, veined like steel cables, and glistening with his throat slime bobbed menacingly in the air between them, the fat head flaring angrily as it throbbed so hard it slapped wetly against her abs. Pre-cum poured from the slit in thick, heavy globs, and her melon-sized balls churned visibly, tightening with raw breeding need.

Fuuuuck…that throat was just a warm-up, pretty boy,” Gojira snarled, fangs bared in a predatory grin that made Tanjiro’s stomach drop. “Look at this fat, dripping girl-cock. It’s starving now. I need that tight little femboy bussy. Right. Fucking. Now~!!”

Tanjiro’s eyes widened in pure panic, his voice hoarse and broken. “W-wait! N-No, you can’t! I’m not…I’m a-”

Before he could finish, Gojira’s clawed hands shot forward. She snatched him off the ground like he weighed nothing, spinning him around so his back slammed against her massive, sweat-slicked tits. In one fluid, terrifying motion she locked him into a standing full Nelson! Her powerful arms threading under his armpits, hands clamping behind his head, forcing his elbows high and his slender body arched helplessly backward. His thick, plush ass was lifted high, cheeks spread wide, that smooth, untouched pucker twitching in the open air right above her throbbing cockhead. His legs kicked uselessly, green-and-black checkered thigh-highs still half-torn around his calves, platform geta dangling from his toes.

“G-Gojira—please—ahh!” Tanjiro squeaked, voice cracking. His small cock was still traitorously hard, leaking onto his own stomach, but his mind was spiraling. ‘She’s too big…that thing just wrecked my throat…if she puts it in my ass I’ll break—‘

Too late.

Gojira grinned wider, fangs gleaming, and slammed upward.

The first thrust was merciless—her entire 19-inch length speared straight into his virgin bussy in one savage plunge, balls-deep on the very first stroke. Tanjiro’s eyes rolled back instantly, a broken, high-pitched wail tearing from his throat as his belly bulged obscenely outward, the fat outline of her cockhead clearly visible under his soft skin. His plump asscheeks clapped loudly against her hips, the impact rippling through his fat booty like waves.

FUUUUCK YES!” Gojira roared in pure bliss, hips already jackhammering upward with brutal, piston-like force.

THWAP! THWAP! THWAP! THWAP!

The wet, fleshy sounds of her melon balls slapping his ass filled the burning village. “That’s it! That’s the good shit! Look at this fat fucking femboy bussy swallowing every inch! So tight, so hot, so fucking greedy! I love boys with big, juicy booties like yours, Tanjiro—fuck, this ass was made for monster cock!”

She showed zero mercy, pounding him senseless in the standing full Nelson, his body completely suspended and helpless, impaled and bouncing on her raging futanari dick. Every upward thrust lifted him higher, only for gravity and her hips to slam him back down, forcing her cock even deeper. His tongue lolled fully out now, drool cascading down his chin as his eyes crossed completely, brain melting under the onslaught.

Gojira leaned in, hot breath against his ear, voice dripping with filthy dominance. “Feel that, slut? Every vein, every inch stretching your boy-pussy wide open! You were strutting in here like a big bad demon slayer~! Now you’re just my personal breeding bitch! Gods, I love big-booty boys so much…the way this fat ass jiggles every time I slam in—fuck—it’s perfect! I’m gonna breed you so deep your guts are swimming in my cum!”

Tanjiro’s mind shattered. ‘Too deep! Too big! She’s splitting me~! I’m a man, I’m a slayer…but it feels so good~! My insides are melting~! Her cock is rearranging me! Oh gods I’m gonna—‘

“Gonna cum inside!” Gojira snarled, pace turning feral, tail lashing wildly behind her as her massive tits bounced against his back. “Breeding instincts are going crazy—gonna flood this femboy womb until your belly swells like you’re carrying my eggs! You’re mine now, Tanjiro! My cock-drunk, big-assed little cumdump! Take it! TAKE EVERY FUCKING DROP!”

Her hips blurred, pounding him harder, faster, the obscene bulge in his stomach sliding up and down visibly with every thrust. Tanjiro’s lolled tongue hung slack, broken moans and gurgles spilling out as his own little cock spurted uselessly into the air, body convulsing in the full Nelson hold while Gojira laughed and railed him without pause—loving every second of wrecking the pretty femboy slayer into a drooling, ass-stuffed mess.

The village burned. Tanjiro’s mind burned even hotter. And Gojira wasn’t stopping until she’d pumped him full.

Gojira’s powerful arms flexed as she suddenly released the full Nelson, letting Tanjiro’s limp, sweat-drenched body drop—but only for a heartbeat. Before he could even collapse fully, her clawed hands seized his slender ankles, yanking them high and wide. In one brutal, fluid motion she folded him beneath her like prey: knees shoved back toward his ears, plush ass lifted off the scorched ground, tiny cock trapped uselessly against his soft belly. Mating press. Perfect. Exposed. Helpless.

She loomed above him, dark skin gleaming with rivers of sweat that ran in rivulets down the deep valley between her massive tits, dripping onto Tanjiro’s flushed, heaving chest. Her golden eyes burned with feral triumph, fangs bared in a wide, toothy grin that promised ruin.

“Time to really rearrange those guts, pretty boy,” she growled, voice thick with lust. The fat, throbbing head of her 19-inch monster kissed his already-abused, gaping pucker, then she slammed down.

All the way.

One savage, bone-rattling thrust buried her to the hilt, melon-sized balls smacking wetly against his tailbone with a meaty THWAP. Tanjiro’s eyes crossed instantly, tongue lolling out in a full, mindless ahegao as his soft belly bulged grotesquely outward, the obscene outline of her cockhead pressing visibly beneath his navel like it was trying to punch through. Sweat flew from both their bodies with every brutal impact; the air around them stank of sex, smoke, and raw dominance.

FUUUUCK YES!” Gojira roared, hips pistoning like a machine gone feral.

SLAM! SLAM! SLAM! SLAM!

Each downward plunge lifted his entire lower body off the ground before crashing him back down, her thick shaft bullying deep enough to make his insides shift and reshape around her girth. “Look at that ahegao face~! Eyes rolled back, tongue hanging, drooling like a broken little bitch! That’s right, femboy. This is what happens when a cute boy with fat tits-for-chest and a juicy ass tries to play hero. You were never a man, Tanjiro. Never could be. Small-dicked little slut like you? You’re just glorified holes for real cocks to wreck!”

She leaned in close, sweat dripping from her fangs onto his open, moaning mouth as she hammered even harder, faster, the wet SCHLORP! SCHLORP! SCHLORP of her pounding filling the ruined village.

“I love me a nice hot lady with big bouncing titties and a fat booty,” Gojira snarled between thrusts, “but fuck—nothing gets me off like ruining pretty femboys. Seeing a young thing like you, all soft curves and plump ass, tiny pathetic clit leaking while I ream your boy-pussy? That’s perfection. You were born to get bred, slut. Say it~! Tell me you’re just a set of holes for monster dick!”

Tanjiro’s mind was gone. Shattered. Melted into white-hot pleasure-pain. His tongue lolled further, drool cascading down his cheeks as his body jolted with every devastating slam. His small cock twitched and spurted weakly again and again, painting his own stomach with pathetic ropes while his guts visibly churned around the invading length.

“P-please…!” Tanjiro wailed, voice high, broken, and dripping with desperate allure. “Please fuck me harder, Gojira-sama~! Ruin me~! Rearrange my insides~! I need it~! I need your huge cock~! Need your cum~! Breed me…fill me up~! Please~! Please~! PLEASE~!!

Gojira threw her head back and laughed—a deep, triumphant, bestial sound that shook the air. “That’s it! Beg like the cock-hungry bitch you are! Look at you—once proud slayer, now just my drooling cumdump! Begging for lady-cock like a good little femboy whore!”

Her pace turned apocalyptic. Hips blurred. Sweat flew in arcs. Her massive tits bounced wildly, slapping against her chest with every downward crush. Tanjiro’s ahegao deepened—eyes completely white, tongue hanging limp, body convulsing helplessly beneath her as she plowed his brains to mush.

Then she roared.

A primal, earth-shaking bellow tore from her throat as she slammed down one final, bone-crushing time burying every throbbing inch to the root. Her melon balls clenched hard against his ass and began to pulse.

“TAKE IT ALL, YOU FUCKING BREEDING BITCH~!”

Hot, thick ropes of cum erupted like a geyser inside him. Pulse after pulse after pulse—massive, endless, scalding. Tanjiro’s belly swelled visibly, rounding out, bloating with her load until he looked several months pregnant. Excess seed gushed out around her buried shaft in creamy white rivers, splattering the ground beneath them, pooling beneath his quivering ass. His eyes rolled completely back, body spasming in silent, overstuffed ecstasy as the cumflation stretched him to his limits.

When the last heavy spurt finally tapered off, Gojira slowly pulled out with a wet, obscene schlorp. A thick waterfall of her seed poured from his gaping, ruined hole, his belly slowly deflating but still softly rounded. Tanjiro collapsed forward onto his face and knees—ass high, face down in the dirt, legs trembling, tongue still lolling, completely mindbroken and blissed-out.

Gojira rose to her full towering height, cock still half-hard and dripping, sweat gleaming on her dark, muscled frame. She planted one foot beside his head, looming over the wrecked femboy like a conqueror.

“Well?” she rumbled, voice low and smug. “What do you have to say for yourself now, little slayer?”

Tanjiro’s body trembled. Slowly, pathetically, he pushed himself up just enough to slide forward and press his forehead to the ground in a perfect, humiliating dogeza. His plump ass stayed high, leaking cum in slow, thick rivulets down his thick thighs. His voice came out small, cracked, dripping with broken adoration.

“P-Please…Gojira-sama…more…I need more cock…more cum…please use me again…breed me again…I’m yours…I’m just your hole…please…please don’t stop…I’ll do anything…just give me more…!”

Gojira’s fanged grin stretched wider than ever, golden eyes blazing with dark delight.

“That’s my good little femboy slut,” she purred, already stroking her swelling length back to full, terrifying hardness. “Get that fat ass up. Round two’s starting now.”
