“That was a fun day at the gym.” I thought while looking at my pumped biceps in the mirror. I’m Keiji, a jaguar truck driver from Kyoto. While on the job, I was paired with a forest cat named Ryoma. He’s a year younger than me, laid back, lazy, but has an air of positivity I find contagious. He makes me smile, and I love working with him. We’d go from city to city, transporting goods, and on our breaks we would pick a restaurant or fast food joint and have ourselves a feast. It’s fun watching Ryoma eat, and even more fun to see his belly grow rotund. I could rub that furry sphere all day.

I’m more on the muscular side. I workout at my home gym in the garage. Then, after my protein-filled breakfast, I get in front of the mirror to check out my body. Bulging biceps, broad shoulders, chiseled pecs, and a pretty flat stomach too. I let Ryoma get his paws all over my body when we’re in bed together. Perks or being roommates and dating. “Looking big and handsome, Keiji.” I said to myself while puffing out my chest.

I was so caught up in loving myself that I heard Ryoma let out a whistle. My ears tilt up, and I crank my head, seeing the shirtless cat let out a laugh while leaning against the door rail. “Don’t mind me. I’m just enjoying the show.” He walks towards me, giving me a kiss on the cheek while pressing his big belly against my side. I feel my heart skip a beat, and my fur stands on end by his touch. “We got a long day today. Gotta deliver stacks of packages to Hiroshima, so hurry and get dressed.”

“I will. Just one more minute.” I lick his cheek, and pat his belly. He ruffles my hair and walks out of the bathroom. I watch him walk away, let out a sigh, and tilt my head down. Every time I get a feel for his belly, I get lost in thought. How does it feel being so big? Would I look good with a belly? I always had a good metabolism, so I don’t gain weight easily. I would like to have a belly just to know what it's like. I run my paw down my abdomen, humming to myself. Before I lose myself again, I grab my work shirt, my company hat, and walk out of the bathroom.

It’s been a few hours since we left. We’re on the road, driving down a highway overlooking Nippon’s gorgeous mountains and rivers. I’m the designated driver, and Ryoma navigates me, reading the map and pointing out the best routes to take. We like to listen to music, eat snacks, and talk between stops. Been doing this for 5 months now, and it’s become my favorite part of my routine. Whenever we run out of stuff to talk about, we stare at the road, drinking in the peace and serenity of Animalands nature. My eyes weren’t focused on that though. At stop lights, my eyes wander towards Ryoma’s belly peeking out of his shirt whenever he stretches his arms and yawns. Sometimes he catches me, and teases me in different ways. I always thought that I wouldn’t ever find a mate that accepts my uhh, kinks, but I’m thankful that Ryoma did, and that he’s into it too.

Anyways, we park at a truck stop to put gas in the tank and grab some more snacks. Before Ryoma got out, I tapped him on the shoulder to get his attention. “What’s up, babe?” He asked.

I tap my fingers on the steering wheel and let out a sigh. “Ryoma. Can I ask you a question?” He nods, folding his arms and waiting for my question. “What’s it like having a big belly?”

“Huh.” He smiles. “You know, ever since we got together, I had a feeling you loved my belly.” A shy smile formed on my muzzle. I let out an awkward laugh while adjusting my hat. He looks forward, and tilts his head down while rubbing his belly. “Well, it depends on who you ask. If you ask me, it feels amazing.”

“Yeah? What do you love about it?”

“I like feeling it, jiggling it, doing belly bumps with other guys, and I get to eat as much as I want without feeling self-conscious.” He smiles before continuing. “Plus, having a bigger presence in a group feels nice. I bet you know, being so buff and all.”

“The attention is nice, yeah.” I said while resting my head on the steering wheel. “The truth is, I want to be like you, but I can’t seem to gain more weight. High metabolism is really getting in the way.”

“Heh. That’s cute.” He said while patting my shoulder. “Then I should encourage you to eat more. Too bad we don’t have the luxury to spend more money on food.” He pulls his paw back, opening the glove compartment and taking out his wallet. “But Keiji, listen. I like you no matter what your size, so make sure getting fatter is something that you want. Okay?”

“Uhh. Yeah. I promise that is what I want. Thank you, Ryoma.”
We both share a kiss before he opens the door, sliding off the chair and landing on the ground. He stretches, and lets out a big yawn. “Well, I’ll get gas and snacks. Be right back.”

I grunt to affirm him, and relax my body. I stare at the horizon, feeling the cool breeze blow on my face. “Ryoma and I, two big cats with big bellies. That’d make me very happy.” I said softly.

I get lost in my imagination again, thinking about various ways I could gain weight fast. The classic way is to stuff myself with pizza. Or I could get a hose connected to a keg of chocolate milk shake and guzzle it down. Replacing my protein powder with mass gainer powder is another option. The thought of gaining weight had me excited, I couldn’t stop rubbing my stomach.

I closed my eyes, lost in my thoughts, when suddenly a knock on my window shocked me back to reality. Eyes widened, and mouth agape, I crank my head to see a huge wolf in a ninja outfit waving at me with a friendly smile. I’m pretty cautious about strangers, but something about this guy had me curious. I roll my window down. “Uhh. Can I help you?”

“Yes. I’m Zan, a ninja. I’m donating clothes to anthros in need, and I was looking for someone with an extra large frame to give these to.” He shows me a set of sleepwear. Made of cotton with a red and black flannel pattern. The tag stitched onto the front says that it’s a double extra large size. “I don’t mean to be rude, but you’re a big guy. I think you would look great in these.”

“I mean. They look great, and comfortable, but it’s one size too big for me.”

“So? You’ll grow into them, won’t you?”

“Huh?” I feel a chill up my back. “Are you assuming I want to get bigger?”

He flashes a toothy grin. “Heh. That’s the vibe I get from you. The desire to get bigger.” He lifts the pajamas to my point of view. “And these aren’t just any ordinary PJs. These are magical pjs that can make your dreams come true.”

Magical pajamas that grants wishes? I highly doubt that. I almost wanted to decline and roll my window up, but the temptation was starting to pull me in. This guy is giving away these fresh new sleepwear and expecting nothing in return. Even if it is a prank, I don’t see any harm in taking these off his hands. I take a breath, and extend my paw. “I’ll take them.”

“Thank you. I promise you’ll thank me later. In fact, I’ll even throw in a bonus, here.” He gives me a bottle labeled, ‘Mass gainer shake’. “To help with your wish.”

Sealed tight. I inspected the bottle, seeing a label with a face of a lizard and snow leopard plastered on it. “Made by Doctor Kustaa Lee, promising to help anthros gain weight. Huh.” I put it in my bag. “Thank you, Zan. Are you sure you don’t want anything in return?”

“Just email me if your wish does come true. You can find it on my food blog.” He winks, lifting his shirt and exposing his massive belly. I can feel my face get warm staring at him. Then it hit me, this is the same wolf that I follow on social media! I let out a gasp. Before I said anything, he pressed his finger towards his lips and shushed me. I close my muzzle and nod. He backs up, and disappears in a gust of wind. He really is a ninja, I thought while staring at the sky.

After Ryoma came back, I showed him the pajamas I got from Zan, but left out the part where they grant wishes. We resumed driving our truck to our destination, delivered the packages, and took it all the way back to Kyoto. It was late at night when we got home, so we ordered a pizza just before we got home. It came right as we put on our sleep wear. I was wearing the flannel sleepwear, despite it being too big for me. Good thing it had strings so I could tighten the waistband or I’d be waddling around with the pants around my ankles.

It was 10pm now. Ryoma was already under the covers while I stretched my body. He let out a chuckle while scratching his armpit. “You usually sleep in your underwear, babe.”

“Well, I wanted to try them at least once.”

“Alright. It’ll keep both of us nice and warm.” He grabs a remote control, and pushes a button to turn off all the lights. He lays on his back, and puts his paws beneath his head. “Haaa. Goodnight, Keiji.”

“Goodnight, Ryoma.” I sit on the bed. Before I lay down, I put my paws together, close my eyes, and make my wish. I needed to be specific, or else the wish might go wrong. I think for a minute, until I decide how I want my weight gain to go. “I wish to wake up 100 pounds heavier.” Yeah, 100 pounds should be enough. I take a deep breath, then I grab the mass gainer shake from my night stand, and guzzle it down. Eating or drinking something before bed makes it easier for weight gain, so I’m going to give my wish an extra push. As soon as I set it down, I hear my belly gurgling. I put my paw on my stomach, feeling some rumbles. “Working already? Hmm…” I get under the covers, and close my eyes, drifting to sleep.

The next morning, I can feel the sun shining on my face. I open my eyes, staring at the ceiling. I lick my lips, smack them, and rub my eyes. “That was the best sleep ever.” I did sleep pretty well. I lay my arms on the bed. Something was different. I felt heavier, something was pressing down on my stomach, and there’s a sensation in my neck that was new to me. I let out a grunt while putting my paws on my cheek and neck. It felt like some fur grew on me overnight. I press my paws against the bed and try to lift my body forward. I feel something getting in the way, something pressing against my legs and. I let out a gasp while laying back down. As soon as I tilt my head down, I see something big that wasn’t there last night. A belly! “Huh!?”

I spring from the bed, getting on my feet, and look down. My body got fatter! I press my left paw against my belly, and my right on my chest. They felt soft, firm, squishy! “This can’t be real. No way.” I say to myself. I pinch my cheek and wait for a beat. “I’m awake!” Then I stomp towards the bathroom. Looking at myself in the mirror, I definitely looked bigger. Only one way to know for sure; I unbutton my pajamas, my huge pecs and even huger belly spill out, and I’m left completely flabbergasted. I drop the shirt on the floor, and stare at my new body. “Holy crap.”

I had to get a feel for my new body. First, I look down. My flat stomach was gone, replaced with so much fat. My belly sticks out so far that I couldn’t see my toes. I run my paws down my sides, squeezing and pulling them. They’re so warm, so soft. Then I move them towards my navel. I pinch the bottom and lift it. It’s so heavy and firm, like pizza dough. I drop it, it bounces and jiggles a few times. The sensation made a giggle escape my mouth. Then I dig my finger into my navel; it’s so deep. I couldn’t help but pull it up and lift my belly again.

Next was my pecs. They are not sculpted and flat anymore. Now they’re filled out with fat, jiggling whenever I twist my body. I caress them slowly, then lift them up. The sensation felt like having jello on your paw. I squeeze them like stress balls. “So soft. I think I still feel some muscle in them somewhere." I didn’t mind that I lost muscle, though. I still had a huge chest, even if they are man boobs now.

Speaking of muscles, the next thing I looked at was my arms. My forearms still looked muscular, but there was definitely a layer of body fat in my arms. Flexing them still showed some biceps, but now I had flab that kinda obscures my triceps. I’ll have to get used to that sensation of jiggling arms, but I couldn’t help but laugh. I pull out my phone, opening the photo app and flipping lenses. I turn my body, so I can look at my back. Still broad, still has some muscle, but my belly really rounded out my lower back, giving me some big love handles. If I was more flexible, my paws would be all over my back.

What next… I lifted my leg, it felt much heavier. I decided to pull my pants down and back up against the wall. My tree trunk legs were even thicker thanks to the newly formed layer of fat. I was beaming, running my paw up my thigh and slapping it. These are the legs a sumo wrestler would be proud of. I let out a laugh, then turned my body. I lift my tail to get a good look at my big round butt. “Heh. Now I’m really caked up.”

I feel like I explored my whole body. I lean against the sink, lifting my belly, and setting it on top. I put my paws on my face, feeling some fat on my cheeks and neck, but not much has changed. I was already a scruffy jaguar, I just have softer cheeks now. “My wish did come true. I’m huge. I wonder what Ryoma will think of this?”

“Think of what?” I let out a gasp, turning my huge body towards my huge boyfriend. His eyes widened, staring at me silently for a moment. “Keiji? How the hell did you get so fat so fast?”

“Uhh… My wish came true?” I said with an awkward smile.

“Hah. I know magic is real, but we are far from wish granting. Did you drink some mass gainer or something before bed?”
“Actually, I did. Maybe it was just the milkshake after all.” I furrow my brow, questioning if my pajamas were even magic at all to myself. I quickly get over it though, and stare at my massive belly.

“Well, wish or no,” He said while walking towards me. He slaps my belly, and starts rubbing it. “I love the results. How does it feel?”

“It feels amazing…” I said softly while blushing. I let him rub my belly for a minute, until the sound of it gurgling makes him stop. “And… I feel really hungry.”

“I bet. Haa, the things I want to do to you, babe.” He said with a smirk, and eyes glinting with mischief. “But we’ll talk about it after breakfast.”

I nod. We stare lovingly into each other's eyes, then press our lips together. Again, and again. He had his paws all over me, and I had mine on his. The days we spent together got even better now that I’ve gotten so huge. I did have to buy a new wardrobe, though, but good thing I’m really good with money. All that matters is that Ryoma and I are happy.

…and by the way! I still go to the gym. My buddies were shocked by my new weight. Some didn’t understand why I did it, but others were happy for me. In fact, one of them immediately went in for a hug when they saw me. I’m a strong, cuddly jaguar.

The End!
