My name is Yorimasa Mita, and I have a confession. I love fat girls. There are guys who love big boobs and guys who love big butts, but with fat girls, you get all of those plus a big belly. A girl who eats a lot is really cute, and it’s just my luck that I’m living with three of them. The Kominezaki sisters let me live with them, and all of them are beautifully overweight. Nanaka, Ruru and Ranko are each a different kind of curvy, and I had a hard time choosing between them as to which one would be my favorite.
Ultimately, I ended up picking Ranko. She was the prickliest of the three sisters, a year younger than me, a tsundere girl who didn’t want a man living at her house. But behind those cute pouts was someone who was as lonely as I was, and she’s adorably tubby. Though she’s the least fat of the sisters, she’s still 190 pounds of pure flesh, with a round belly that makes her look like a tanuki. It’s like a huge rubber ball that’s fun to play with, and that belly signified our relationship getting closer.
It was when Ranko was lying on the couch, her pajamas open and her tits and belly hanging out. I stuck my erection in her belly fat, rubbing it back and forth against those soft, fleshy folds until I came into her cleavage and over her face. Fucking a fat girl’s belly was a life-changing experience, and one that made Ranko appreciate me a little more. She said that she wanted to give me something special for my birthday, which had come around during my stay at the sisters’ residence.
Once the gifts were exchanged, Ranko took a large slice of the cake we had picked up and let me watch her eat it. She was devouring the cake and the chocolate within, letting it slide all over her body. She finished one slice, and then went on to another. Ranko knew that I loved watching her eat. She had unbuttoned her shirt just before we began, letting her belly that had grown far beyond a muffin top stick out, pushing her against the table as she kept eating and eating, filling her stomach with delicious sweets. She had also gone out to a fast food restaurant for lunch, eating a larger burger that had left her stomach absolutely bloated with food by the time she finished. She was full and panting, sweating profusely that her clothes were sticking to her body.
Ranko invited me up to her bedroom. She told me to wait a minute behind her door. After patiently waiting, my erection growing with every passing minute, I heard her invite me. Opening the door to Ranko’s surprisingly cute bedroom, I saw her standing in front of me wearing nothing but a ribbon wrapped around her body. It covered her pussy and one of her nipples, but not any part of her belly. She had been careful not to wind it through her ass cleavage. Covered in sweat, her tubby body before me was the sexiest thing I had ever seen. Giving me a cute pout, Ranko looked at me.
“Don’t think I’d do this for anyone,” she said. “I’ve had three big meals today, so my belly’s the fattest it’s ever been, and I’m all sweaty. I know there’s nothing you’d want more for your birthday than me. I am cute, after all.”
“Ranko, thank you so much!” I said, diving for her. I pulled on the ribbon, unwrapping it and letting it fall for the floor. Ranko’s rather large pink nipples came into view. Her entire body was dripping with sweat. I moved over to her, planting a kiss on her lips. The inside of her mouth still smelled like cake. As our tongues crossed, I grabbed all over her body. Her fat, flabby butt, her chunky belly, and even her decently sized tits. While Ruru’s were the biggest, Ranko’s fatness meant that she had a pretty good pair of boobs for a girl with her proportions.
After a few minutes of the smell of Ranko’s filthy sweat going up my nostrils, I stopped kissing her and moved my tongue down to her breasts. I licked the sweaty underside of her boobs, tasting the rich, salty fountain that had been gathering under her chest. It was deliciously salty, a perfect appetizer as I moved my tongue up, closing my lips around one of her nipples and sucking. I slurped at her pink tip, tugging at her breast. As I pulled, I saw her belly fat start to shake. Ranko was moaning, her body starting to get hotter as she blushed profusely. Her body was being honest about her intentions, even if her tsundere nature prevented her from being honest.
I moved my mouth away from her breasts, asking Ranko to lift her arms so I could move to her underarms. There were a few strands of orange hair there, trapping her pit sweat all in one place. The sweaty, meaty smell coming from her armpits was rank, enough to make my cock rock-hard. I licked around her armpit, sucking the drops of sweat out of her flesh as the ripe stink of her body odor covered my face. Ranko looked down at me with a harsh glare, wondering how I could be so shameless.
“Just because I don’t exercise much doesn’t mean I don’t sweat,” Ranko said. “I got my pits all rank just for you, so you’d better appreciate how much they smell.”
“I love it!” I told her. “This youthful stink coming off your body is incredible.”
“But don’t you want to play with my lower body more?” asked Ranko. “When you told me my belly was cute, it made me really... happy. It’s full of food, so it’ll never be this fat normally. Go on, enjoy it, you perv.”
“Ranko, your belly is the best!” I told her. I pushed Ranko back onto her bed. She landed against the springs, making the bed creak as the silhouette of her chubby belly rose up in the light of the room. I pounced onto the bed after her, stripping down to only my underwear. My cock was pitching against my briefs, making a tent that made Ranko have to hold in her gasps. She knew I was hard, but the size of my dick from seeing a fat girl always left her a little shocked. She wasn’t used to being thought of as sexy.
She grabbed for my underwear, pulling them down and taking out my cock. Ranko rubbed the underside of my glans with her finger, teasing out more of the precum that already sparkled on my cockhead. That smug look on her face was keeping my erection going. “You know what I want for dessert? What’s in your balls,” she said. “I want your white sauce topping everything inside my fat belly.”
I loved it when she talked dirty. I placed my hands on each side of her chubby round belly, sinking my fingers into her sticky, sweaty belly flesh. Her stomach was tauter than usual after her full dinner, but it still retained much of her soft squishiness that I adored so much. I kneaded her belly fat in my fingers, feeling the heat rush to Ranko’s stomach. She moaned as my hands groped her belly. I watched the shape of her belly button change as I teased her stomach, all while my cock rubbed against the soft part of her thighs. All that teasing had covered her belly in sweat. Having already savored her breasts and armpits, I wanted to help myself to the main course.
One lick only covered a small part of her belly. I moved up across her curves, replacing the beads of salty sweat that had built up on her belly with my saliva. It was just as delicious as the rest of the sweat I had licked off her. After a few strong licks, the smell of her stomach teasing my nostrils, I moved my tongue towards her belly button. She had a fairly wide and deep indent to her navel. I stuck my tongue inside, as eager to play with her belly as I would be giving her cunnilingus. It had been a while since I ate out her pussy. Her belly tempted me much more.
“Why are you so focused on my belly button?” asked Ranko. “You’re not going to make me cum like that.”
“Your belly can make me cum in another way,” I said.
I got to my knees on the bed. My hot cock hovered above Ranko’s flabby belly, now shimmering with my saliva. I lowered my cock onto her stomach, moving my hips to smack my meat against her meaty belly a few times. I beat it like a drum, using my cock as the stick. Every smack of my dick against her taut, overstuff belly made it ripple with a pleasantly fleshy sound. The red shape of my cock was left behind. Ranko cooed from the vibrations. I grabbed my hands onto her belly once again, and did my favorite thing. One thing that only fat girls can do. Any girl who’s sufficiently curvy can use her tits or her ass to massage a cock. Only the chubbiest of girls can do the same thing with their delicious belly fat.
I bunched Ranko’s belly fat against my cock, wrapping it like a hot dog. The sticky, sweaty belly flesh enveloped my cock in the best way. I embraced its softness, and started moving my hips. I thrust my cock through Ranko’s stomach, bringing it across her squishy expanse and towards the underside of her tits. Ranko moaned as my leg brushed up against her plump pussy. Her lower lips rubbed against my leg as I continued massaging my cock and balls with her fat stomach. It was incredible. My member was enveloped on all sides by her overwhelming softness. I could feel the heat and movement of her food sloshing around inside her cute chubby belly.
“I wanted your cum inside me,” said Ranko.
“Let me cum here first,” I said. “Your cute belly needs to be glazed.”
“Okay, but you have to stick it inside me next,” Ranko said.
Her belly fat jiggled and wobbled underneath my cock. Every thrust of my dick brought it closer to climax. The heat of her belly and the heat of my cock were mixing, until I could no longer tell where hers ended and mine began. The vibrations of my thrusting were spreading across the rest of her body. Her tits and thighs shook as well, making all the beads of sweat I had licked off return to her skin. I was no longer able to hold out against her fatness. My cock twitched, and exploded into her belly folds.
Three ropes of thick cum sprayed from my tip, spraying onto Ranko. I pulled my cock away, leaving a slimy trail that rolled down her belly and sunk into her belly button. My cock kept throbbing, pumping out more small spurts of his seed. I always came so hard when I fucked her belly. Ranko scooped some of my cum onto her finger, licking the tip and savoring my salty release. “You’re extra thick today,” she said. “Most guys wouldn’t cum this hard from fucking a belly.”
“Yours is special,” I said. “Ranko, please let me use your ass!”
“If you think you can fit your perverted cock in there,” Ranko said. She turned over on the bed, the springs squeaking as her big belly pressed down on the bed springs. She smacked her ass with her hand, making it jiggle and drawing my attention. “Come on, birthday boy.”
I buried my face inside Ranko’s squishy butt cheeks. Her hips were wide and round, with the shape of a pumpkin hanging off her back. I pulled her cheeks apart to get a better look at her pink asshole. Ranko had been prickly about getting to know me, so she never ventured to let me near her ass for very long. I stuck my nose between her ass, letting her soft cheeks smack the sides of my head, and took a deep whiff of Ranko’s anal smell. It was a mix of sweat and the smell of digesting food. Her natural smell back there was super erotic, enough to make my cock spring back to life.
I kept sniffing, wanting to memorize the smell of her ass until I would feel it every time I took a breath. Ranko felt my warm breath coming out of my nostrils and rolling back onto her ass. It made her pussy leak. I wasn’t going to be using her pussy today, but my goal was to teach her how to cum with her ass. If she was as sensitive there as she was on her belly, she would be feeling it all over once I teased her butt enough. Ranko pressed down on my head, burying me even further inside her squishy ass.
“How long are you going to sniff my butt?” she asked. “Stick it in me if you’re so hard.”
“If you insist,” I said, pulling my nose away from her butthole. The smell lingered around my face. I got into position and let my cock rest between her ass cheeks. The softness of her fat ass surrounding my cock got it back to a full erection. My semen was still coating the shaft and the head, making it easy to slide into her tight back hole. I lined up the tip of my cock with Ranko’s anus, pushing my cock against the wrinkled hole. With a forceful thrust, the tip of my penis was swallowed up by Ranko’s butt. Her cheeks shook as she strained to squeeze my cock inside her.
It was incredibly tight inside her. The same fatness that made fucking her pussy so good, the extra weight from her big belly, extended to her ass too. The warmth and tightness of her butt squeezed my cock from all sides, trapping me tightly inside her asshole. I squeezed her ass cheeks between my fingers, massaging her butt as I pushed the rest of my shaft inside her. A popping noise followed, and Ranko’s butthole had swallowed my entire cock. My balls were being rubbed by her fat ass, smothered in their pillowy softness.
“Ranko, I love this!” I said. “Your butt’s holding me tight.”
“Start moving. I’m feeling all tingly after you licked me, and I want to cum, too! Show your girlfriend some love!” Ranko said. “Fatty-loving perv.”
“I wouldn’t want to do this with any other chubby girl but you,” I told her.
I began to thrust inside her ass. Even when I pulled my cock out, I couldn’t see the entire length of the shaft. Her butt cheeks were too big for my cock, smothering it on the way in and the way out. When I plunged back into Ranko, every flabby curve on her body jiggled. It started from her ass cheeks, spreading down to her thighs and all the way around to her belly, before reaching her tits. That sweaty smacking sound was like music to my ears. There was so much Ranko to grab onto. I kept my hand on her ass cheeks for the time being, moving steady in my thrusts.
“Your dick is so hard inside me!” Ranko said, moaning loud enough that her sisters could hear it from the other room. “Is my flabby ass turning you on that much?”
“All that and more,” I told her.
“Happy birthday,” she said. “I hope you can keep using the gift of my butt for a long time.”
“I’ll never get tired of your ass,” I said.
I moved my hands around to her stomach, eager to sink into that plump belly of hers once more. I squeezed down on her stomach, close enough that I could hear the birthday cake inside. I kept pumping my cock in her ass, and the vibrations on my palms felt incredible. Her body was shaking and wobbling with every thrust. Her moans were cute and charming. The more I fucked her tight ass, her standoffish demeanor faded away. Her face was bright red and every other breath was a moan. The happiness on her face as I pounded away at her ass was an erotic side of Ranko that I hadn’t seen before.
As my hands moved across her barrel belly, I rubbed my cum into her skin. It mixed with her sweat to give her skin a glow that made her look even more beautiful. The bed springs squeaked under us, fighting against Ranko’s weight as I dug harder and harder into her ass. Ranko turned around and opened her mouth. I could smell dinner on her breath. I put my tongue inside her mouth, our tongues locking together as we exchanged a deep and wet kiss while my hands traveled all over her pleasantly fat body. We closed our eyes while we kissed, and Ranko felt my dick even more strongly inside her.
We broke our kiss after a minute. It felt much longer than that. As soon as the saliva between our tongues broke, Ranko resumed her moaning. She was getting close to cumming, and so was I. While I yearned to stay inside her ass for as long as I could, the tightness of it was pushing my cock’s endurance to its limits. I put one hand on Ranko’s breast, and the other on her belly. I squeezed down on them both, moving until my fingers pinched down on her hard pink nipple. Ranko’s asshole clamped down on me, and my finger pressed into her deep belly button.
“Cumming! Cumming! I’m going to cum...” Ranko moaned.
“Ranko!” I shouted.
“Masa!” she cried out.
I pushed my cock in as deep as it could go. I blew a second load, hot and heavy, inside Ranko’s ass. The wrinkles of her butthole caressed my cock as rope after rope of hot seed spilled inside her bowels. Ranko panted heavily, worn out from such a hard fucking. She placed her hand over mine on her belly. She could feel the warm surge of spooge coming into her ass, and loved it. Her pussy started to drool down her thighs, leaving a slimy trail on her legs as she came. She lightly squirted after experiencing her first anal orgasm. The pleasure was just as great as when I had done her pussy.
“Ranko, I hope you have room for dessert!” I said.
“Huh?” Ranko asked.
My cock was still spurting loads. My second shot was just as thick as my first, and still going. I pulled out of Ranko’s butt with a wet popping noise. I briefly stopped to admire her wide open asshole, now dripping with my load, and quickly maneuvered my cock around to her mouth. Ranko’s mouth was wide open in shock. I rested my cock on her tongue, and Ranko’s lips closed around my dick. She sucked on it by pure lustful instinct. As I shoved it in her mouth, Ranko’s stomach let out a cute growl. She craved my semen, and her body knew it.
“Thah was jush in my...” Ranko said, her words muffled by dick. The smell of my still ejaculating semen and the inside of her own ass went up her nostrils. It was a rank smell, but Ranko kept sucking. Her nipples were fully erect, those pink points sticking up from her fat tits in a signal of her arousal. Her pussy kept drooling out its love juice. I thought about touching her clit, but there would be no need. She was still in the middle of her orgasm, and I would much rather touch her belly.
I blew the last of my load in Ranko’s mouth. I kept my cock inside her until it had gotten half-hard, and pulled it away, leaving a strand of semen linking my cockhead to her lips. The spice of her own ass had gotten mixed in with the semen. Not even that could stop Ranko’s appetite. She swirled the cum around in her mouth for a few moments before swallowing it down with a loud gulp. As promised, my white sauce was on its way to top off her dessert.
“Why’d you put it in my mouth after it was in my butt?” Ranko said. “Tell me if you’re going to do tha- URRRRRRP!” Ranko’s tsun side was interrupted by a loud and rumbling belch from the depths of her overstuffed belly. Her boobs and belly shook as she failed to cover her mouth. The air from her cum burp blew past my cock, making it twitch. That was enough to get me almost hard again.
“Ranko, even your belches are ero-cute!” I said.
“Don’t expect me to burp on your dick just because I know you like it,” Ranko said.
As Ranko lay down on her bed to rest, a squeaking sound came from behind. Some of the cum that hadn’t made its way down into her ass was farted back out, splattering against the inside of her ass cleavage and the back of her thighs. Ranko didn’t even respond. She did it again, looking at me with a grin on her face. She placed her hands on her belly, guiding me towards her navel one last time.
I buried my face in her belly while Ranko squeezed my face from the sides with her fat. She laughed to herself, and looked down past her cleavage. “Happy birthday,” she said. “I ate so much today that I think I put on a few more kilos. Want to confirm it with the scale before we bathe?”
“Do I!” I exclaimed.
Ranko was beautiful as she was. Getting fatter could only make her more beautiful. She’s my junior and my girlfriend, and I’m ready to spend even more days with her like this.
