My name’s Colby. I’m a marine iguana living on the island of Moonshale in the Animalands. I grew up here, working construction to develop and renovate buildings. Our island is rich in magical energy and rare crystals, which makes us the target of invaders sometimes. Thankfully, we have a strong team of Liberators that protect us, and make the bad guys regret entering our territory. I’m not a fighter, so I tend to hide whenever it happens.

After the fights, I go with our construction team to repair any buildings caught in the crossfires. I may not be strong, but I help keep things organized. I was hired for my expertise in efficient building designs. Although, the guys do often tease me for my small appearance. They’re not aggressive though, because they still give me treats for doing a good job. I like working with Rocky’s construction crew.

To be honest, I didn’t always tolerate their teasing. I started learning to stand up for myself after I met this awesome new guy that moved to the island and joined our crew. His name is Hugo. He’s a large, quiet alligator who obediently follows instructions. I wanted to be friends with him, but for some reason he kept his distance from us. Was it because he’s shy? Or does he get nervous around people? I didn’t know at the time, but I didn’t want to pry. I gave him his space until he was ready to open up to us.

As the months passed, Hugo and I started getting close. We walked home after work, we hung out at the tavern to talk, and soon we started going out swimming and hiking together. Turns out he is a chill and funny guy. I really grew fond of him, and how protective he gets when we encounter bad guys or the creatures. He’s very strong, fighting off his enemies with his bare hands. I love how his movements and attacks came straight out of sumo wrestling. I was enamored by his heroism and power he displayed. It was after that he and I confessed our feelings for each other. Now, we’re living together, as a couple.

Since then, Hugo and I have been living happily under the same roof. I can’t believe that a year has already passed since we got together. Moonshale has made great progress in development, the anthros are happy, and we haven’t had an invasion in months. Hugo’s also opened up about himself more too. So have I, actually. In fact, I admitted that I fell for him because I like how big he is. Large arm muscles, a broad back, legs as thick as steel beams, and my favorite part of his body, his round belly. Firm yet soft. Smooth despite his scales. I could lay my head on it all day.

“Hey Colby. Since the island has been peaceful lately, I’m thinking of training for sumo.” Hugo was telling me about his recent interest in competing while we’re preparing breakfast.

“Is there a tournament coming up?”

“Yeah, in Nippon. Junichiro and Yaomao’s training has helped me a lot, but there is something else that I've been considering.” He pauses, looking down at his belly while putting his hand on top. “The wrestlers are huge, and I’ve been thinking I should put on more weight if I am to match their size.”

That caught me off guard. I gulp, and blink a couple of times. “I-I wouldn’t mind helping you bulk up, Hugo.”

The gator smiles, pulling me close for a kiss on the cheek. I felt my heart skip a beat while he let out a soft laugh. “Thanks, Colby. I’m glad I have a mate as supportive as you. I’ll adjust my schedule and diet so that I can start my training.” He grabs his phone and walks over to the table.

He’s gonna get bigger. Honestly, I would love to see him bulk up. I wanna help him, but I can’t imagine how expensive it’ll be to buy all the food he needs. I stare at our pantry, scratching my cheek while deep in thought. He’ll need food dense in calories, carbs, and protein. Of course we must make sure he doesn’t skip on other important nutrients. Maybe if I get him macadamia nut butter, I can start using that in his meals so he gets more calories. Yeah! I’ll cook breakfast first, then after we eat, I’ll order it for delivery.

After Hugo and I eat pancakes and fruit, I grab my phone and order macadamia nut butter, mass gainer powder, and all the ingredients I need at Little Garden’s grocer website. A kind tiger takes a fast boat to Moonshale, where I waited at the port to pick it up. There were two carts packed with everything I ordered, so I tip the tiger, and carry both carts home.

Back at our cabin house, Hugo was in the front yard, doing squats with a heavy barbell behind his neck. He couches down, slowly stands up, and grunts as he stands straight up. He sees me, puts the barbell on the rack, and grabs a towel to wipe sweat off his sweaty body. “That was fast.”

“Phew. Little Garden has excellent service.” Hugo grabs one of the carts while we both walk inside. “I got something very special for you.”

“Special? Hmm.”

While he sat in the dining room, I pulled out a large container of chocolate mass gainer powder. “I’m gonna use this in your meals until you’re at your satisfied weight.”

The gator blinks, grabbing the container and smelling it. “Hmm. Smells pretty good.” He narrows his eyes at the nutritional facts, a chuckle passed his lips. “You must really want to fatten me up.”

“Well I uhh.” I shuffle in place, running my hand up my arm. “I want to help.”

“I appreciate it. Go ahead and use as much as you want.”

I got his consent. Now I can start cooking him high calorie meals to help him gain weight for sumo. Honestly, part of me wants to keep the macadamia nut butter a surprise, just to see his reaction on how fast his weight gain will be. One of the gainers from Little Garden gave it five stars, saying it helped him get huge. I can’t wait to see the results.

From then on, I started using mass gainer powder and butter in his meals. Buttered chicken breasts, pasta, waffles, bread with chili, chanko nabe, cakes, ice cream, and gainer shakes. Everything I made, Hugo happily ate. I watch him devour his chicken, then belt a loud burp. “Haaa. That was delicious. Hmm, the butter tastes different.”

“You noticed? Uhh, yeah. I used a different type of butter.” I kinda struggled to keep my cool. I let out a nervous sneeze and wiped my nose.

“Bless you.” He said while wiping his mouth with a napkin. “Well, I like it. You should use it more.”

Oh I sure will. I couldn’t help but peek at his belly. It was rotund from all the food he ate. If he’s going to get bigger, then I better buy him some new clothes as soon as possible. After dinner, The two of us cuddled on the couch and watched some tv before we went to bed. I gave him belly rubs and I just love how packed it feels.

Two weeks later, Hugo and I woke up early in the morning. I was kind of sweating from the heat. I know it’s summer, but we got an air conditioner running. I open my eyes, and then realize the source of the heat I was feeling. Hugo is laying on his back, his belly sticking out like a large hill in the horizon. The butter is working! He’s getting bigger! I watch him sit up, yawn, and get out of bed. He rubs the side of his belly as he makes his way towards the mirror. He stops, tilts his head, and turns his body, getting a side view of himself. He squeezes his belly with both hands, lifts it, and drops it, his large gut quaking. Hooooot.

“Colby. I seem to have gotten bigger faster than I thought I would. How?” He turns to me, staring at me with a puzzled glance.

“Well, I did my research, and just made food and drinks high in fat and calories.” I said calmly.

“I see. It’s definitely working. Junichiro is totally gonna tease me, but I’ll just give him a good belly bump off the ring during practice today.” He turns to the mirror, flexing his big biceps and using his other hand to get a feel for his large, firm pecs. “But first, let's weigh and measure my waistline. Care to help, Colby?”

I let out a shaky nod, feeling flustered by how big and sexy he looked. We go to the bathroom, and I grab a measuring tape to measure his waistline. He’s 55 inches now! His belly got 3 inches bigger! That butter is amazing! After I measure him, he gets on the scale. He gained 22 pounds! I was speechless! I stare at him while he steps off and pulls his underwear up, the seams are starting to rip slightly. He looks down, smiles, and shakes his tail slowly. “Gonna need some new underwear soon.”

“I uhh, already bought some new clothes for you.”

“Awe thanks. I love you.” He said softly while giving me a kiss.

If this macadamia nut butter is this effective at helping him gain weight, then I am not holding back. I buy another container of butter, and I start working on making more meals packed with calories and fat.

The days go by. Some people were surprised by Hugo’s weight gain, and of course his friends are teasing him, poking his belly and asking him what his diet is. Hugo just laughs it off. I’ve known him long enough to know that he enjoys people calling him big or fat. I don’t understand why, but he says it reminds him of his ex-boyfriend that always complimented on how he likes his large size. I think that’s great.

Hugo’s been loving my cooking. He’s been eating so much that his weight gain has become more noticeable. His neck got thicker, his muscles are growing, and his belly’s getting big and round. He gained 40 more pounds, and his belly is 60 inches wide. His body still has that broad, muscular shape, but you can barely see his muscles under all that layer of fat. In bed, he lets my hands wander all over his body so I could try getting a feel for his muscles, like a scavenger hunt. But I mostly just play with his neck flab and belly. I love pinching the bottom of his belly and caressing my thumb below his navel.

After I play with his belly, he gets on top of me, covering my small frame with his huge body. He’s so warm, so heavy, like a weighted blanket. We stay like this for a while, pressing our lips together over and over until we get tired enough to fall asleep. My boyfriend is a bonafide sumo wrestler now, and soon I’ll get to see him in action.

The next morning, he was the first to wake up. I saw him already out of bed and going into the kitchen. While I get up and look in the closet to grab my robe, I hear him stomping back in the bedroom, holding the container of macadamia nut butter. I shudder as soon as I see it.

“Babe. Was this your secret ingredient that fattened me up?”

I couldn’t tell if he was upset. He had this wild, jovial look in his eyes as he stared right into my soul. I gulp, and find myself with my back against the wall. “Y-you found it? Gulp, Y-yes. I used that butter for all your meals.”

“Heh. I was finding it odd that I gained so much weight this past month.” He leans in close, pinning me against the wall with his huge belly. I gulp, and watch him put his arm against the wall and over my head, his hot breath creeping down my neck. “You are a sneaky iguana, Colby. Was this your idea of a surprise?”

“A-a-are you mad?” I said in a shaky tone.

There’s a beat of silence. His sharp gaze softens, and he lets out a chuckle. “Not at all. I just felt like giving you a scare.” He gives me a kiss on the cheek. “In fact, I love the lengths you went to give me that sumo wrestler body I want. I feel stronger, heavier, and more confident that I’ll bring home the gold. Thanks, Colby. I couldn’t have asked for a more supportive partner.”

“Hugo…” I lean forward, trying my best to wrap my arms around his wide body. “I love you so much. Ever since we confessed our feelings for each other, I wanted to do everything to make you happy.”

He hugs me back, our bodies slowly rocking side to side as we enjoy each other’s embrace. He leans back, staring into my eyes.

“I am happy. You spoiled me rotten, even though I don’t deserve it.”

“But you do deserve it. Anything you want, I’ll do it.” I said with a strong gaze.

The gator smiles, he holds my hand, and we both walk into the kitchen together. There’s a basket of muffins on the table, ready to eat for breakfast. He grabs one of them, breaks a piece off, and turns to me, a smirk crossing his lips. “There is something I’d like you to do.” My eyes widened. I open my mouth, and let him feed me a piece of muffin. While I chew, he pets my cheek. “I’d like to see how you look 50 pounds heavier.”

My heart raced, and I felt aroused. I gulp, and smile. “I mean, I get curious about what it’s like to be a big guy sometimes.”

He feeds me another piece of muffin, slightly bigger this time. The inside of my stomach starts to gurgle. I can feel the effects of the butter already. Hugo chuckles, rubbing my belly with his webbed hand. “Give it a month, and we’ll see just how nice you grow, babe.”

He puts a piece of muffin between his fangs and smiles. I lean in, grabbing that muffin with my mouth while simultaneously kissing him. We give into our passion, and get more intimate together. I’m so happy that I am with someone that shares the same kinks as me. I want to join him in mutual growth, and see what it’s like to walk a mile in his shoes. Life goes on, and the two of us happily live this life together.

The end!
