Work Text:
Mitsuba Marui, the eldest daughter of the Marui triplets, had been personally invited to stay at the Sugisaki household. She knew why, but it was going to be worth it to enjoy the free food and sleeping in a fancy bed compared to her house. Futaba was spending the day at Shinya’s place, and Hitoha was at Tokyo Dome City to see a Gachiranger stage show. Mitsuba arrived at the front door of the mansion with her bag. Her top was a little too small for her waist, showing off her fat belly. According to Futaba’s estimates, Mitsuba’s belly was an I-cup. She had told that information to Marina Sugisaki, the mother of her greatest rival Miku and the reason she had been invited here. Miku was working on her homework, and didn’t hear the door opening from the other end of the house.
“Mitsuba!” said Marina, eagerly greeting her. Despite giving birth to two children, Marina Sugisaki was still young and beautiful, with model-like looks and ample breasts. She had a fetish for being dominated, and nobody was better at that than Mitsuba. She greeted Mitsuba by walking towards her on all fours like a dog. Mitsuba dropped her bag in shock. Marina wrapped her arms around the elementary schooler, grabbing onto Mitsuba’s butt through her shorts. She put her ear against Mitsuba’s stomach. She hadn’t eaten lunch yet, and her stomach gurgled in Marina’s ear. She planted a kiss against Mitsuba’s belly button, leaving a lipstick mark on her navel.
“This won’t do. You need to fill your belly before the fun can begin,” Marina said. “Come.”
“Hey lady, I just got here!” Mitsuba said. “What are you doing?”
She took Mitsuba by the hand and guided her towards the Sugisaki family’s pantry. It was stocked with food. Marina said that Mitsuba could eat as much as she wanted, especially the sweets. Rather than insult her, Mitsuba graciously accepted her offer. She filled her arms with as many treats as she could hold, and hurried to the nearest table. A mountain of sweets was stacked high, all of it for her. She unwrapped the packages and dug in. Marina revealed that she had brought a cake from the local cake shop. The only words printed across the top were “Do-S JS.” Mitsuba didn’t know if she should feel insulted, but she wasn’t going to refuse chocolate cake.
Marina sat at the opposite end of the table, watching Mitsuba eat. She brought in some taiyaki, and Mitsuba ate them with little worries. A sweet potato was added to the mix to break up the sugar, and it went into Mitsuba’s gut with the rest of them. The table top was left covered in crumbs and wrappers. Mitsuba’s flabby belly had been stuffed to its limit. The red around her navel now came from her bloated and gassy stomach, pushed to its limits from the amount of indulging Marina had let her do. Her father would never let her get away with this at home, not in the least because food needed to be shared between the triplets and himself. Mitsuba patted her stomach. When she raised her arm, Marina caught a glimpse of her nipple underneath. Mitsuba wasn’t wearing a bra. She wasn’t big enough to need one. The only softness on her flat chest was from her fat.
“Urgh. I can’t eat another... URP... bite,” Mitsuba said, interrupting her sentence with a burp. “Mrs. Sugisaki, you’re spoiling me.”
“Mitsuba, you’re looking so sexy,” Marina said. “I wasn’t going to start the main event until I had turned you into a perfect little fatty.”
“You witch!” Mitsuba said. “What am I to you, Gretel?” Mitsuba’s sentence was once again cut off by a loud burp. She tried to stand up. The food in her stomach sloshed around, and she felt the need to sit down again. Mitsuba rubbed her stomach, letting out alternating small and loud burps as she tried to hurry along her digestion. All of this was going to turn into fat in a few hours, and Mitsuba was already concerned that she was the fattest of her siblings. Futaba was athletic and lean, and Hitoha was slender and only ate her fill. Mitsuba was, as Marina had said, a fatty. Something that Miku never failed to use as an insult.
“I have something else to give to you,” said Marina. She pulled out a pair of underwear from under the table. These were fancy expensive looking underwear. Not the kind that could be purchased five to a pack for cheap, and had material that was comfortable enough. These were made of high quality fabrics, and available only from catalogs that Mitsuba had never heard of. She realized in an instant, looking at them, that these were Miku’s. The smell coming off them suggested they had been washed. Mitsuba wasn’t going to wear anything that had touched Miku’s smelly pussy.
“This is too fancy!” Miku said.
“I want you to try it on,” Marina said. “You can change in front of me.”
“Perverted woman!” Mitsuba said. Marina swooned at the insult. She felt her pussy getting wet from Mitsuba’s sharp tongue.
“If you don’t change in front of me, you won’t get any more sweets,” Marina said.
“You drive a hard bargain, Mrs. Sugisaki,” Mitsuba said. “Don’t tell my old man about this. He’ll pulverize you if he finds out.”
“Okay. Please hurry and put them on,” Marina said.
Mitsuba took her top off first. Her plump belly and small but visible tits were exposed to the house. Mitsuba’s nipples were rock hard and a cute shade of pink, looking very suckable. Mitsuba had already unbuckled her belt during her sweets binge, and slid it through her shorts before lowering those too. She was wearing a cute pair of pink panties with a stretchy waistband to account for her fat ass. Her panties were the next thing to go, sliding down her legs and revealing her puffy pubic mound, which only had a few strands of hair growing, and her plump butt cheeks to Marina. Her socks were the only thing she was going to leave on.
“Before you get changed, let me take some pictures!” Marina said.
She got on her knees in front of Mitsuba. The eldest triplet struck what she thought were sexy poses, giving Marina uncensored views of her belly, butt and pussy. Marina asked her to spread her pussy. Mitsuba blushed and looked away, opening her slit to expose her pink insides. She got a little horny when her belly was full, and it was showing signs of wetness that were captured with the flash of the camera. Marina saw her clitoris become erect. Even more than her nipples, that was the pink nub Marina wanted to kiss. Mitsuba’s normal underwear had cute animal patterns, at odds with her acerbic demeanor.
Mitsuba slipped on the bra first. She wondered where Miku had even bought this. The bra had slits to show off the nipples, and hers poked through. She faced her ass towards Marina, and stepped into the silky panties. Mitsuba pulled them up her body, fitting them snugly around her fat ass. The panties felt a little tight. She knew it was because she had eaten more calories in a single sitting than she usually had in a day, but panties like this were sturdy. Mitsuba bent over to adjust them, and heard a ripping sound. Down the back of the panties a tear had appeared, exposing her pussy and butthole. Mitsuba felt a breeze from the air conditioner blowing past, kissing her clit.
“Mrs. Sugisaki...” Miku said.
“Don’t worry about it. They can be repaired and Miku won’t even know what happened,” she said. “Let’s go to my bedroom.”
Mrs. Sugisaki had a large bed. She closed the door behind them. Mitsuba turned around for a second. When she turned back, Marina was wearing sexy lingerie. It was from the same brand as the bra and panties she was wearing. Her cleavage was ample and perky, and her butt was round and soft. There were some traces of stretch marks from giving birth, but they were barely visible under the room’s lighting. She wanted to be dominated by Mitsuba. Miku’s room was close by, and she would be furious if she realized that Mitsuba had torn her underwear, so she couldn’t leave. Using her sadistic tendencies against an adult, who wanted them to be used, was weirding her out. Her stomach growled, hungering for more sweets.
“Suck my titties,” Mitsuba said.
Marina moved her face towards Mitsuba’s chest. She stuck out her tongue and flicked it against her nipple, gathering the sweat that dripped around her breast. She closed her lips on it, sucking hard on the pink tip and covering it in a film of her saliva. As she sucked and tugged, Mitsuba felt her pussy getting tingly and growing wetter. Marina stuck her finger up Mitsuba’s pussy, teasing her clit and letting her finger become soaked down to the wrist in Mitsuba’s juices. Mitsuba moaned in sensual pleasure. Her pussy and her nipples were being stimulated at the same time, with the weight of her full, fat stomach adding to the pressure on Marina’s finger.
Her other nipple was sucked on until it was as hard and wet as the first. Mitsuba burped as a wave of stimulation flowed down her body. She had pushed out so much gas that her stomach felt lighter, if still very taut. Marina laid down on the bed. She took off her panties, revealing her hairy motherly pussy to Mitsuba. She had never been wetter in her life, with love juice dripping from her slit and sweat getting mixed up in her pubes. Mitsuba crawled onto the bed behind her. Mitsuba made her way to the head of the bed, and squatted down over Marina’s face. Marina’s view of the ceiling was blocked out by Mitsuba’s fat ass. Her puckering grade school butthole was over her face, so hot and so close that Marina could smell it.
“You’re so popular you could have any man you want, but you want me to sit on your face? What a filthy woman,” Mitsuba said. Once she had removed Miku’s ripped panties, Mitsuba plopped her head on Marina’s face. Her butthole was rubbing against her nose, and her pussy was over her mouth. Marina’s tongue darted out, starting at Mitsuba’s clit and licking across her wet slit. Mitsuba shivered when she felt the tongue hit her pussy. Sometimes a hand had wandered down there when she was bathing with her sisters, but this kind of intense, focused licking was new. The smell of her grade school pussy covered Marina’s face, mixing with the scent of her sweaty ass. Marina pushed her nose further into Mitsuba’s ass crack, until she was rubbing against the wrinkles on her winking butthole.
Taking a deep whiff, Marina sucked up the scent of Mitsuba’s asshole. The food she had given her, the arousal, she could smell all of it, going into her nostrils and up to her brain. She held Mitsuba’s ass in her hands, taking another long whiff until her tongue went inside Mitsuba’s slit. Mitsuba stopped for a moment. She raised her ass in the air and slammed it back down on Marina’s face. The fat in her butt cheeks jiggled, vibrating on top of the older woman. Marina put her tongue back inside, slurping out a long strand of Mitsuba’s love juice like a ramen noodle. The wet sounds and pleasurable sensations made Mitsuba’s lower body tingle, growing hotter and sweatier from the touch of her rival’s mother.
“Wait, the old man’s not here. I can say all the naughty words I want!” Mitsuba said. “You like licking my pussy, don’t you? My sixth grade cunt?”
“Yes, I love it!” Marina said.
“Eat my butthole too, slave!” Mitsuba demanded, smacking her ass with her hands to make it jiggle.
As Mitsuba bounced on top of Marina’s face, she realized she couldn’t see Marina underneath her. Her pudgy belly was blocking her view below her waist. She moved her body about, letting her belly jiggle about. Marina swirled her tongue around inside Mitsuba’s pussy, digging into her folds. Mitsuba closed her legs around Marina’s face, trapping her with the smell of her crotch and sweat. She adjusted her position, getting her asshole above Marina’s mouth. She was open-mouthed in excitement, drooling at the chance to taste Mitsuba’s precious butt with her mouth. Of the many pictures of Mitsuba she had secretly taken and then masturbated to, her butt and her belly were in focus the most. Her tongue whirled around Mitsuba’s wrinkles, getting her saliva into every part of her ass cleavage.
“My butt’s... so sensitive...” Mitsuba said with heavy moans.
She had been the victim of a kancho prank during class, which had left her butt sore for the rest of the school day. In comparison, the way Marina explored her ass with her tongue felt quite good. The smell and taste of her ass was strong and bitter. Marina thought it tasted awful, but kept licking because it was so terrible. She wanted to bring Mitsuba to orgasm on top of her face. Mitsuba became aware of her hard, throbbing clit between her legs. Hitoha had told her that it was called a clit, but didn’t elaborate further. Futaba liked to hump her pillows, not understanding what it was, only that it felt good. Mitsuba had looked at hers in the mirror, and tried touching it, but stopped when the sensation was more extreme than she was used to. Now, with Marina licking her pussy and asshole, she understood that she should have gone further.
“Girls can cum with their butt too,” said Marina, speaking into Mitsuba’s asshole. Mitsuba shivered when she felt her warm breath on her butt. Mitsuba tweaked her wet nipple, sending another spark of pleasure towards her lower body. Marina pulled her tongue out of Mitsuba’s ass with a wet pop. Mitsuba hadn’t burped in a few minutes, yet her stomach was gurgling. A squeaky hissing noise blew into Marina’s mouth. The bitter taste intensified, attacking her nose and mouth at the same time. Mitsuba’s moaning became quiet. It must have been those sweet potatoes that she had eaten earlier. She looked down at Marina.
“Mrs. Sugisaki, I didn’t mean to...” she said.
“MORE!” Marina shouted. “Punish me more!”
“You asked for it, you slut,” Mitsuba said.
Marina’s licking turned rough. Mitsuba blushed, and the tingling in her pussy reached its apex. She leaned back, letting her belly growl, and squirted onto Marina’s body. Drops rolled down into her mouth, while the rest of it soaked her breasts. Mitsuba came several times in a row. The fuzziness in her head made her lose count. Sweat dripped down her body. At last count, she must have orgasmed over ten times in a row. Her pussy was sopping wet, and Marina’s face and breasts were drenched in her immature love juices. Feeling cheeky, Mitsuba extended her hands and groped Marina’s breasts. She kneaded them in her little palms, shaking them about with her nipples pinched between her fingers.
“You’re a dirty lolicon, but you have some really big titties,” Mitsuba said. “I could play with these things all day.”
“Mitsuba... I’m going...” Marina moaned.
The bed sheets had gotten soaked in Marina’s love juices. The comforter and the sheets below were wet with her nectar. The bed was marked with her scent. Mitsuba tweaking her nipples pushed Marina to another orgasm. Mitsuba finally released her from the smothering grip of her butt cheeks. Marina took the first breath of fresh air she had gotten in several minutes. She spread her legs wide, showing her hairy pussy. Slurring her words, she pointed between her legs. “Mitshuba! Eat mama’s pussy for her...”
“I thinK i know what to do from you slobbering over mine,” Mitsuba said. “You deserve a reward.”
Mitsuba released Marina’s breasts from her grip, and went to the foot of the bed. She put her head between Marina’s thighs. Mitsuba sniffed. Marina’s pussy was very wet, with her creamy love juice leaking out. Though hesitate to taste it at first, Mitsuba slurped it off her slit. She gulped it down, and went back in for more. Her little tongue licked Marina’s clit, gathering up as much juice as she could. The inside of her pussy was warm and tight. She couldn’t get very deep inside. When she looked past Marina’s waist, she was playing with her boobs and moaning. Having Mitsuba playing with her pussy was a dream come true, and she was going to cum over and over again. After a few licks, Marina sprayed Mitsuba in the face like a sprinkler, drenching her from the shoulders down.
Excited by the warm spray, Mitsuba shook her hips back and forth. She licked Marina’s thighs, gathering the last drops of her squirt that had come out. Marina thanked Mitsuba for giving her the best orgasm she’d had in years. Marina sat up in bed and hugged Mitsuba. The smell between her cleavage was as intense and sweaty as the smell between her thighs. Mitsuba was smothered by Marina’s breasts. Something that boys and men of all ages would pay a generous sum of money for, and she was enjoying it for free. Her displeasure was not as strong as previous visits to the Sugisaki household. Mitsuba would have rather been hanging out with Yoshioka.
While she was trapped in Marina’s embrace, Mitsuba’s fat belly squished against Marina’s own. She saw Marina’s hands moving down her back, gripping her ass cheeks and squeezing them. She loved how soft and squishy Mitsuba was to the touch. Mitsuba sat opposite her on the bed. “Are we done yet? The sweets aren’t enough to compensate for this. You need to pay me. I’m sure even half of Miku’s allowance would be more than I’ve had in my life.”
“But we’re not done,” Marina said. “We’re so sweaty. Why don’t we take a bath?”
The water was drawn. A few minutes later, Marina was seated in the bath. Her heavy breasts floated above the water’s surface. Mitsuba put one foot in the water. Marina had been keeping her eyes focused on her butt, and then her belly, when she was soaping herself up before getting in. She stepped into the water, and the level rose. The tub was on the verge of overflowing. Mitsuba moved about, and a splash of hot water ran over the edge. Mitsuba was hoping Marina wouldn’t say anything about her weight causing the tub to overflow. She didn’t need words. Underneath the water’s surface, Marina was groping her belly, sinking her fingers into her stomach fat.
“I hope you can stay for dinner,” Marina said. “If Miku doesn’t finish her food, you can have her share. I want to make you even fatter so you can punish me harder.”
“Stop calling me a fatty!” Mitsuba said. She sighed, feeling a rush of calming pleasure when Marina slipped a finger inside her butthole. The two of them were getting hot. Mitsuba wouldn’t be able to stay in the water for too long. Hot with arousal and embarassment, the two of them felt like they were going to pass out. The door to the bathroom slammed open. Miku stomped in, carrying the wet, ripped pair of panties in her hand.
“Eldest! Mother!” she said. “What the hell are you doing?”
“Miku, dear. Mitsuba and I were just having some fun,” Marina said.
“Her fat butt ripped my panties!” Miku said.
“You can buy a new one. You’re rich,” Mitsuba said defiantly.
“Get away from my mother!” MIku said.
Mitsuba stood up. She was naked in front of her rival, but she didn’t care. Water dripped down her body, getting into her fat folds on her belly. “I wish I could, but your mom’s a perv who wants me to sit on her face.”
“You were enjoying it when you were on my face. You even came,” said Marina.
“Re... really now?” Miku asked. “That’s enough!”
All of her anger had worked Miku into a sweat. Marina got out of the bath to start preparing dinner. She left Miku and Mitsuba naked in the bath, facing opposite each other and glowering. Mitsuba got out first, changing back into her normal panties. She ended up staying for dinner, returning to her home after the sun had set. Futaba and Hitoha approached her, curious to know what exactly she had been doing at the Sugisaki place. Miku refused to elaborate further. Gossip travels fast, and by the next day in class, everyone would know that Mitsuba was unusually close to Mrs. Sugisaki, much to the jealousy of the boys and confusion of the girls.
