The Oni Sisters (Patreon)

An inspired idea after seeing the oni family art by https://twitter.com/otherbenpai. Just a pair of strongfat oni sisters I immediately started crushing on, gave a quick ask to write for them, and threw this together with some minimal input. Didn't have names for them so I threw together the Mimi, Momo and Mama off of Momotaro, that kid who fought the oni.

So just some super strong, chubby lesbian femdom stuff!

Joan was a seasoned warrior, having gone through more adventures than any other swordswoman she knew. She’d driven off bandits, toppled evil wizards, and even taken down dragons. It was no surprise that when she reached a small village talking of the unstoppable onus that lived in the nearby mountains, she felt a surge of confidence that she could once again help the helpless. They assured her there was no need, but fame… that is, the reward of a good deed done would be well worth the effort.

Joan carried a huge and heavy sword on the back of her armored body. She was tall and strong while keeping a feminine beauty about her. Her lovely face and long, wavy red hair was a striking thing of beauty to see atop the thick suit of polished platemail. Her breastplate lived up to its namesake, pushed out far enough to house her generous chest in comfort and protection as she marched up the rarely-used mountain path.

The way was grassy and pleasant to start with, but the higher up she went the more she started to see fallen frees. Clearly the work of monsters, from her experience, and powerful ones at that. Joan just steeled herself, eager to prove herself once again as she marched into a stretch of level ground.

That was where she found her target. The oni was a blue-skinned sort, not that Joan had encountered any others before now. She was broadly built, dressed in chest wraps and a loin cloth with further crude bandages wrapped around her forearms and palms. She had long and wild white hair with a bluish tint to it, giving it a snowy look as it whipped around behind her. A pair of simple braids were tied on either side of her face to keep it out of her eyes, and a solitary horn poking out from the top of her head. She was almost a foot taller than Joan, with plump breasts (even for her size) bouncing around despite the wraps. A necklace of fangs or claws danced around on her wobbly chest, and a potbelly jiggled as it sagged slightly over her loincloth. A trail of slightly darker hair grew in a similarly untamed state from just below her navel into a denser patch vanishing under her crude clothes.

The oni was busy practicing with her large and brutal blades. She swung two weapons that were closer to machetes than swords, clanging them noisily as she focused on attacking a mass of stone. Her weapons sank in an inch or so before she’d draw them back, rapidly assaulting the boulder in some sort of training.

Joan could hardly believe her luck. The big oaf was distracted and creating a hell of a racket, making it child’s play to sneak up on her. The scrappy blue brute clearly pushing her focus and effort into her training; sweat was running down her hair and chubby curves, and the exotic musk hit Joan’s nose well before she was within striking distance.

She finally arrived just a few yards behind her, watching the oni’s wide blue behind bounce around wildly with her powerful swings. It was momentarily distracting, but she focused and lunged in, driving one of her deadly thrusts into the beast’s back.

The sword clanged as it struck, as if it had hit an enchanted steel rather than her bare back. It suddenly occurred to Joan why no one had already eliminated the onis. The tip of her heavy blade slipped clumsily aside, sliding down the oni’s back and getting awkwardly stuck between her ass cheeks. Joan blushed, then paled as the oni turned around. She gave the human a puzzled look, as if she had barely even felt her backstabbing.

“Huh? What are you doing here?” the blue beast of a woman asked.

She gave a rather careless whip of her arm, swinging behind her. She sliced the boulder completely in half without even looking as she remained more intrigued by the intruder. The power behind the blow made Joan go paler still, so she threw all her might into another swing. This one was meant to slice open the oni’s belly, but when it connected, the soft gut jiggled for a moment before the greatsword got stuck in the fold of fat it had created from the impact.

“Oh! You’re another one of those tiny challengers that keep coming up to us?! That’s cute!”

The oni flashed a grin tipped with sharp canines. She gave another sharp sweep of her blade and the demonic steel cut Joan’s sword right in half like it was made of cardboard. The warrior flinched and fell back, landing on her ass and scooting away in a very un-warriorlike fashion. The oni grinned and pointed one of her swords at her.

“Then I’ll give you the same choice as the rest of them. You can either be target practice for my training, or you can serve as our harem girl for the day! What do you say to that?”

Joan swallowed hard as the strange choice was laid out to her.

“Ha-harem girl?” she asked in confusion.

The oni grunted and lowered her sword. She used the other one to scratch her shaggy head.

“Phooey. They always pick that one. How am I going to get some proper weapons training when mom and sis won’t practice with me?”

“When your what!?”

Joan’s shock was answered by a rhythmic, thunderous set of footsteps behind her. She looked back to see a second oni coming towards them, and this one was bigger in every way.

The new oni was fatter, bustier, and taller than the one that had so easily defeated Joan. She had hair and skin of matching coloration, but she had a single, huge slab of a sword on her shoulder that Joan could have used as a very cramped bed if she was so inclined. She had full, pouty lips, chubby cheeks and a button nose, but the rest of her face and eyes were covered in wavier, uncut hair that went past her ass as wide as a wagon. She wore a loincloth and wrist wraps like her sister, but an even heavier gut hung over the front. Her top was even worse at its job; a strap of tiger fur wrapped over the middle of her breasts, pinning them down while her huge, slightly inverted nipples were left dangling out of the bottom. A notable belly hung over her loincloth while jelly rolls jiggled at her sides, but her thick arms showed incredible muscle mass that were twice the size of her little sister’s (and blowing Joan’s own biceps completely out of the water). While the first oni was taller than he was, this new one was another foot bigger.

While Joan froze at the sight, the first oni blushed a shade of purple across her cheeks. She pouted as the bigger monstergirl arrived. Joan somehow noted that the new oni had a pair of horns atop her head, but that was pretty clearly the thing that the younger oni was the least jealous of. If nothing else, the fatter monster was dragging the corpse of a bull-like creature the size of an elephant behind her like it was a bag of potatoes. Somehow, the smell of her fresh kill

“Hey, Mimi. You found a playmate,” the bigger sibling noted with a warm and lazy smile.

“Momo! I only just found this one! And she chose harem, so I get to keep her,” Mimi whined.

She threw down her swords, burying their blades in the ground. The younger oni grabbed Joan by the collar of her armor, lifting the redhead off her feet like she was just a heavily armored kitten.

“Aww. That’s cute,” the bigger but calmer oni sighed.

“But Mama does like us to share, so…”

“No fair! I found her, I get to try her out first!”

“Oh, you’re just worried I’m gonna squash this one. I’ll go easy on it. I promise,” Momo cooed.

Jean squirmed in her grip, managing to grab one of the shoulder straps of her armor. She gave it a yank, falling out of her breastplate and dropping to the ground.

“That’s it! I quit! I’ll go home! Just don’t let the fat one eat me!” the panicked heroine shrieked.

She managed to scramble a couple of feet before a wide, powerful hand palmed the top of her head. Momo still had her hair in her eyes, but the intense strength in her grip made Joan freeze up rather than risk getting hurt, even accidentally.

“Squirmy little thing, isn’t she? But you left a few pieces on this one, sister dear…”

Momo grabbed the front of Joan’s undershirt, and with a single tearing motion, she ripped every scrap of clothes and armor off her body. While the naked redhead fumbled to cover herself up, Momo shoved her under one of her beefy arms like she was just a loose book she didn’t have a free hand for. The intense smell of oni sweat was especially potent tucked under one armpit, invading Joan’s nostrils and numbing her mind with the overbearing scent.

“Let’s get this one to the cave and have some fun, huh?,” Momo said as she led Mimi and her latest catches back to their home.

----

The cave turned out to be a comfortable mess. It was much tidier than most monster caves that Joan had been to, but it gave her little comfort. Momo set her meaty monster beside the cave entrance and threw their captive into the cave itself. Joan landed on a huge heap of furs that clearly served as their bedding, being the softest thing in sight besides the sisters themselves. The naked heroine started to scramble across the cushy spread, but Mimi had already caught up to her. She cast a shadow over her just before she dropped her wide ass on Joan’s back, crushing her beneath her doughy cheeks and pinning her down. She was clearly nude beneath her loincloth, the musky heat washing over her prisoner. The whole place smelled of chubby, fighting wild women without access to a shower, but it was especially overpowering underneath her. Joan gagged as the air was squeezed out of her.

“Quit squirming,” Mimi scolded her as she pulled at her chest wraps.

The oni wiggled her hips, grinding them Joan down while smoothing out a comfortable spot in the heap of crude blankets. Joan coughed for air, her tongue lolling out breathlessly. Momo’s slow, booming steps approached her before she squatted down in front of her. Her tits and belly wobbled to a stop as her thighs parted, granting Joan a perfect view of her crotch and its thin, curly bush of snowy white.

“Can’t wait to get a taste, hmm? You humans are always so easy going when you come up here. I love that about your kind~!” Momo giggled.

Momo cupped her chin and pushed Joan’s head up enough for the giantess to stoop down. She kissed her firmly on the mouth, making Joan’s eyes go wide with shock as she realized her tongue was still out of her mouth. Whether she meant it as a joke or was truly confused, Momo took it as an invitation to make out with the trapped crusader. She could barely move while she was under Mimi’s quarter-ton of ass, and she was so breathless she had no choice but to keep her mouth hanging open. Momo’s large thick tongue bullied its way past her lips, slurping and sucking on the helpless human’s face. She gave some muffled squeals of protest and surprised pleasure. The bigger sister’s plump lips and tongue knew what they were doing as they toyed with the human’s lips.

“Hey! Don’t hog her for yourself! I’m the one who caught her!” Mimi protested huffily.

Momo giggled some more, setting her broad and soft body jiggling as she withdrew from the smooch. Joan coughed wetly, choking on the oni’s abundant slobber from the kiss.

“Heehee~! Don’t worry. We’ll make sure this little morsel lasts,” Momo chimed.

With Momo retreating enough to let her take over, the relatively smaller oni sat up and pulled their captive out from under her buttock. Joan panted appreciatively after being crushed underneath her, but she was still being manhandled by the massive women like their personal toy. The shaggy-haired oni girl cupped Joan’s ass with one powerful hand, lifting her with ease and pulling her crotch up to her face. Mimi buried her face into her pussy, smacking and slurping noisily as she feasted on Joan’s womanhood. She gasped loudly and grabbed her single horn, While she was smaller than her sister, Mimi’s tongue was still huge enough compared to the human to more than fill her pussy. It stuffed inside her, curling and licking hungrily as she wolfed her down like a peach. Joan’s entire body shuddered in her grasp, too shocked and aroused to be grateful that her strong fingers had such a firm grip on her ass.

“AhhhhHAAA~!” Joan wailed as she held on tightly.

Mimi blushed more purple a little at the wordless praise, which just made her snack more greedily on the human’s pussy. Her lips smacked and her saliva mixed with her pussy juices. Soon Joan was leaking a sloppy mix of their fluids, leaking precum that dribbled over Mimi’s breasts and belly. Her powerful tongue flexed and slapped against the fallen warrior’s hardened clit, getting her more turned on that she could remember and at record time.

“W-wait~! I’m about NNNH~!”

Joan shook like a leaf, humping Mimi’s face uncontrollably. She squirted a mess of cum over the chunky oni’s face, but she just as quickly latched her mouth onto it. The blue girl gave a pleased hum as she suckled on her pussy, gulping down her juices as she tipped her back like a living mug. She seemed to ignore Joan’s mind-blowing pleasure as she chugged her orgasm, finally parting her lips with a satisfied sigh.

“Mm! Human juice is so nice~! Especially straight from the tap!” she gushed, licking her cummy lips.

“Mmhm. Now what was that about sharing?” Momo pried.

She plucked Joan’s ankle from Mimi’s clutches, letting her dangle by one leg. The strongfat monstergirl licked her plump lips hungrily, tracing her short, dull claws over the adventurer’s skin until goosebumps sprang up in their wake. Her head was still spinning from the orgasm, and being hung upside down wasn’t helping her recover in the slightest. Momo’s fangs flashed past her smiling, drooling pouty lips.

“Don’t hurt me,” was all Joan could think to squeak out. “I didn’t mean to call you fat!”

“Oh don’t be! I took it as a compliment. An oni should be proud of their feasting~!”

She patted her saggy belly, making the blubber ripple around her broad palm right in front of Joan’s face. The heroine gulped, still not fully convinced she wasn’t about to be eaten if the monsters weren’t so horny to play with her.

“But I guess I’ll be a little more greedy than my sweet sister.”

Momo left Joan dangling in her grip, but she tore off her loincloth with her free hand. The oni leaned her hips closer while pulling on Joan’s upper back. It all thrust the human’s face into her groin, engulfing it in the soft and wet blue flesh of her pussy. Momo’s belly rested on her chin, molding around to make room for her. Momo’s fuzzy pubic hair tickled her jaw as her gut hung down on her, her muffled yelps buried in her pussy lips. Her legs kicked around in a panic as she tasted the musky monster’s snatch, but they only bounced off her huge and gelatinous bosom. The further jiggling just made Momo smile wider.

“Ooh, like that. It’s nicer when they vibrate~!”

The oni traced her free hand’s claws down Joan’s thigh. She tensed and spasmed as she approached her overworked pussy, doing just what Momo wanted her to. She gasped and sputtered, her panting breath and parting lips making her that much more pleasurable for the oni to toy with. She hummed happily, hugging her muscular arm around Joan’s waist and squeezing her body between her breasts. They squashed around to mold around her as her hand went lower, palming the back of the heroine’s head to push her face in deeper.

“Just like that, my sweet little thing~!” Momo purred as her fat thighs hugged Joan’s face like a plush but powerful vice.

Joan could only gurgle as her face was lost in all that blue flesh. Her mouth was forced open in shock and from the squeezing of her captor’s legs, sputtering so her lips and tongue rubbed against anything they could reach. She made a slobbery mess of Momo’s groin while the tubby monster’s pussy smeared its juices over her face. Momo gave a long, delighted moan as she started humping her wide hips, thrusting a hard, dark blue clitoris into Joan’s mouth to facefuck her to the fullest.

“Oh~! Ahh~! Little lower… MMMMMHM~!”

With a lusty grunt, Momo gushed a small tidal wave of cum that slapped Joan in the face. She immediately choked on the warm juices spilling into her nose and mouth like it was trying to reach her brain and force her to memorize the oni’s scent. It was strangely intoxication, and Joan found herself gasping for air while unable to close her mouth and lapping all of it up obediently. The lightheadedness of her orgasm and complete surrender to the onis had made her especially submissive.

“What a lovely little appetizer,” Momo sighed as she rolled her hips, smearing her wet womanhood over Joan's face.

“Me next!” Mimi insisted jealously.

She grabbed one of Joan’s legs, pulling at it to try and yank it from her sister.

“Aww, but I wasn’t done,” Momo groaned as she held onto Joan’s other leg.

The human wailed as she was hung upside down, her thighs aching as they left her spread eagle between their powerful claws. Momo raised a finger for Momo to wait, gently taking both of Joan’s legs before letting her drop. She landed on her back in the pile of patted down furs, panting for air and gulping down the lingering oni cum. Momo sat on Joan’s chest, eclipsing the human’s line of sight with her enormous ass while  pressing Joan’s legs apart to offer up her pussy towards her sister.

“There. Help yourself, and I’ll take the top half. That way we both get what we want, right?” Momo offered cheerily.

Mimi considered it briefly before giving a tsundere little pout.

“It’ll do,” she conceded as she knelt down in front of Joan’s legs.

Mimi lifted them up over her broad thighs, thrusting her hips forward to clap her pussy into Joan’s. Her strong thighs pushed her hard enough that Joan felt her body rock like she would have been sent flying from the force of her humping. The pinning weight of Momo’s bulky body was all that kept in place, for better or worse. Mimi gave a soft moan as she started to grind against Joan’s pussy, her own swollen clit bumping and bullying around the human’s. Joan’s eyes fluttered and she let out a mewling moan as she was already being hurried towards her next orgasm. She gripped at the furs beneath her, trying to brace herself for the sexual climax.

Momo’s shadow fell over her as she did. She had just a moment to gasp a desperate breath before the mountainous ass squashed over her face, burying her between her buns. Joan gave a horny moan as Momo arched her back, throwing her huge ass back to push the pinned human even deeper. She had no choice but to pant down the musky air beneath her. Momo humped back and forth, dragging her dripping wet pussy over her body while Mimi tribbed with their prize. The youngest started to moan, playing with her own breast as she started humping faster. Joan’s tongue found itself being dragged along Momo’s asshole and along her crack, which made her wail and moan especially loud as she wiggled it in Joan’s face.

“Ohh~! Ahh~! I love… love how these little humans get in all the right spots!” Momo gasped, smiling breathlessly as the sisters rode on the trapped human.

The girls were just starting to build up towards their peak when Joan spasmed beneath them. Her mind was fogged up with their smothering flesh, making her squirt again like she was addicted to being their sexual plaything. The extra lubricant just made Mimi hump smoother and harder as her clit slid along her own, sending paralyzing surges of pleasure through Joan’s entire body. Her shuddering just made her vibrate and moan more against Momo’s ass, making the fatter oni bounce up and down. Her cheeks clapped against Joan’s face appreciatively as they rode her with increasing excitement.

“Nnf! Yes! So good~!” Mimi found herself mewling out loud, breaking her tougher exterior.

The chubby monstergirls broke into lusty cries as they both orgasmed, gushing over Joan in a pair of sloppy cumshots. The bulky women came just as big as they looked, squirting enough pussy juice out to coat the majority of Joan’s body. She wouldn’t be able to wash the chubby women’s scent off her for days as their cum soaked into her skin, hair and privates. Her eyes rolled back as her tongue and hips stuck out instinctively. Joan came again as Mimi pulled on her legs, wrapping them around her pudgy waist as best she could reach. Momo’s eyes were still behind the veil of hair but her mouth opened wide enough for her tongue to loll out past her fangs and lips, drooling over herself in pleasure as her ass clenched greedily around Joan’s tongue.

When their horny roars finished echoing off the cave’s walls, the girls finally climbed off her. Joan could barely think straight, wracked with aches and orgasms and a constant daze from being passed around by the horny onis. She drooled out some of Momo’s cum while Mimi’s trickled out of her pussy. Her once powerful limbs felt drained and limp as she laid in the soaked animal skins. Even then, the girls weren’t done with her. Mimi pulled up on the human’s red locks, making her dangle from them like a marionette. Despite her satisfied grin, she leered down at the listless intruder.

“Don’t go quitting on us yet. I haven’t got to try that pretty little face of yours,” the youngest oni threatened.

“Ohh, but she’s so good at it. Let me have another go~!”

Momo moved in on her as well, taking a handful of Joan’s hair. The human found herself squashed between the oni sisters’ portly bellies, a marshmallowy abyss of sweaty fat and happy trails of hair. She was utterly blinded as her cheeks were squashed inward, bumped around by the squabbling sisters. Their guts smeared around her face, molding around until she found herself trapped between their groins. She mindlessly lapped at their slits, only to get bumped back up to their stomachs again as they vied for position and adjusted her to match their own height. Their human toy couldn’t do a thing to stop them, kissing and worshiping their tummies and sucking their clits and pussies as she took anything she could into her mouth in an attempt to satisfy them.

She seemed completely lost in the deep maze of flesh until a new, singsong voice boomed out loud enough to penetrate the earmuffs of blubber.

“Oh, girrrrls~! Mama’s home, and she brought dinnerrrr~!”

The sisters promptly took a step back from Joan. Their squeezed together bellies had been all that were holding her up, so she found herself falling face down and ass up on their bedding. She saw a third oni entering the room, plump like the others but with a petite plumpness to her that made her look more soft and maternal. Her wide, child-bearing hips and wobbling, milky blue bosoms didn’t detract from the huge muscles bulging in every part of her arms. A single horn grew from her forehead, parting her bangs and leading back into a massive braid that reached past her knees with two shorter ones bound in brass rings down her cheeks. She wore slightly finer clothes than her more savage roommates, a thick silken rope tying a loincloth in place her breasts were loosely wrapped. She had something resembling a katana wider and longer than a man across her back, a barrel of rice as big as herself, and some kind of dragon being dragged behind her by the tail.

“MAMA!” the sisters chimed happily to see their mother return.

Mama furrowed her brow slightly as she studied the scene before her. She didn’t even have to enter the cave to take a sniff at the air and detect what had happened. She leaned to one side to look past the broad oni girls and spot Joan’s groaning, cum-covered body.

“Oh, girls,” Mama tutted, shaking her head.

“Another one? You need to remember humans are delicate things. You need to learn to pace yourself more or else you’re going to break them.”

“Sorry, Mama,” Momo and Mimi said in unison.

Mama trotted past them and pulled up on Joan’s arm. She mumbled incoherently, which was normal for whenever the oni mother found the fucked silly remains of a traveler that her girls had caught. She patted Joan on the shoulder consolingly.

“My my my… you’ve clearly had enough, haven’t you? Well let’s fix you some tea and a bit of dragon steak over rice and send you on your way. And if you see any heroes on your way back, you tell them to stop traveling up this far.”

Mama clicked her tongue pityingly.

“When will they learn we don’t need their help up here? There’s some dangerous beasties up here they just can’t handle, and we can’t keep rescuing you every time you get in over your heads..”

Momo and Mimi cleared their throats, avoiding meeting her eye as they stifled their snickers.
