My Brother's Secrets

Chapter 5: Enlarging Marvin

I looked at my younger brother, smiling as he slept, cuddling up to Marvin's belly. Marvin was awake too, holding Chris to him. He looked over to me, grinning, before we leaned in, meeting halfway to kiss softly. I murred softly, sliding my tongue into his mouth, feeling him suck on it. Marvin gently slid off of the bed, before he took my paw, guiding me out of the room.

"Mmm, Ryder, I want to do something special with you."

I tilted my head. He chuckled, seeing my confusion, before he went into the kitchen. He opened the freezer, examining it for a few seconds, before he nodded, clearly content with what he saw.

"I could always stand to gain a few pounds."

I chuckled softly, examining his fat body. He looked to be about 250 to 260 pounds. It's true, I did enjoy the thought of making the fat dog hit 300 pounds. And he could clearly tell what I was thinking, as a huge grin crossed his face. He went into the living room, sitting down as I began cooking food. I could hear his belly gurgling from here, eager for a good stuffing.

"You know, Ryder, you look a little underfed."

I looked over at him with a growl. He knew he struck a nerve, whistling softly as he put on a movie. I looked down at my body, seeing my pecs and abs. I had put a lot of work into these! I shook my head, huffing, before I continued to cook.

I opened an eye, rubbing it. I sat up, looking around. I was in Ryder's bed. I sighed softly. Maybe it was all a bad dream? I slid out of bed, before a delicious scent hit my nose. It smelled like steaks. I lifted my nose to the air, murring at the taste, my mouth watering as I walked out into the hall, seeing the large, naked Marvin sitting on the couch.

"M-Morning, Marvin."

He turned, looking up at me with a smile on his face. Gods, he was handsome. I looked into the kitchen to see Ryder cooking up a storm. Steaks, pizzas and fries.

"What're you doing, Ryder?"

He grinned at me, chuckling as he pulled me over, holding me close as he pressed his lips to mine, pulling me into a deep kiss as he held my hips. He pushed his tongue into my maw, playing with my tongue as he stroked down my back. I could hear Marvin coming over. He pressed his cock into my ass, making me moan into Ryder's mouth. Ryder chuckled, before he got me to get on all fours.

"There we go. Now, sweetie, open wide and go 'ahhh'."

I looked up at Ryder, opening my maw as I felt a cock slide into my maw. I blushed, moaning as both of my mates thrusted in and out of their respective holes. I panted as I closed my eyes, sucking on Ryder's cock. I was loving this. This attention was pretty darn great. I murred, looking up at Ryder with a grin upon my face. He smiled down at me, clearly happy to have me back.

I looked around my hotel room, sighing softly as I stroke a paw through my short hair. I was in town on a business trip, having received a promotion. I looked in the mirror quietly, seeing that Golden Retriever looking back at me. I looked at the picture in my wallet. It was a picture of Ryder, Chris and myself.

"I should come visit you guys."

I had been asked to move back to my home city if I wanted my promotion. My girlfriend, however, chose not to come. She didn't want to live here. She said it was too much for her. I knew deep down, however, that she was seeing another man. So, we broke up. And now, I had no one. But that's fine. After all, I got to see my brothers again. I don't remember the last time I saw them, but it was a couple of years at least. I grabbed my wallet and phone, before I headed out the door, heading to their home.

****

I licked my lips, murring as I cuddled up to Marvin, my tailhole oozing cum. Ryder was in the kitchen, cooking up Marvin's feast, while I was with Marvin in the living room, rubbing his belly and tasting Ryder's cum. Marvin was holding me close, a finger buried in my ass, fingering me, as we watched TV. It was cartoons, nothing special, but I was enjoying that finger.

"How's that feel, Chris?"

I look up at Marvin, smiling as I kiss him softly on the cheek.

"It feels nice, Marvin. Thank you."

I could hear Marvin's belly growling next to me as he was clearly hungry for the incoming feast. He was pretty eager for that food from the sounds of it. Ryder cleared his throat from the kitchen, before rolling the food over on a cart that we had stashed in the pantry. I looked at the food, then up at Marvin. Drool was oozing from his maw. I giggled softly, patting his soft belly as he immediately got to work on the food.

"Mmm, Chris, get on the floor for a moment."

I blinked, nodding as I got on the floor, sitting cross-legged. Why did he want me on the floor? As soon as I thought that, he answered me.

"Ok, Chris, lay on your belly, then lift up your ass."

I blushed, knowing where this was headed. I nodded, laying on my belly, before hiking my butt up into the air, presenting it to the two males. I could hear a groan, followed by a thick cock being pushed into me. I then felt a belly on my back, meaning that Marvin had mounted me. He began thrusting, making me moan.

"Mmm, I can't say no to this."

There was a tough push, as I looked behind me. Ryder had mounted Marvin, and was shovelling food into his maw. I blushed, as Ryder thrusted, making Marvin thrust into me. I moaned out, arching my back, feeling that gut swell slowly on my back...

****

I grinned, thrusting hard in and out of the lardo German Shepherd's ass. I reached around him, stroking over his swelling gut, as he began stuffing food into his own maw. I held his hips, my knot beginning to form as I fucked his ass, making him moan in between bites of food. The German Shepherd was packing on the pounds, and quickly! He only finished half of the food on the cart, and already it was starting to get hard to see Chris from back here.

"A-Ah, harder, Marvin."

I could hear Chris moaning, so I knew that Marvin hadn't hurt him. I sigh a little in relief as I continued to thrust in and out of Marvin, before POP! My knot slid right into the fat male's ass, tying us together. I groaned in ecstasy, leaking pre cum into him. I could hear Chris moan out louder, in a sort of pained way. I guessed that he had been knotted too. The pleasure was becoming too much for me. Plowing this ass, watching the big male get bigger, I was so close to blowing my load! I watched as food item after food item disappeared into the male's maw, before it showed up on his gut and his hips. Within minutes, the food cart was emptied, and the large, flabby male let out an almighty belch. I couldn't hold it back anymore, blowing my load into the male's ass. I huffed, laying against his back as I closed my eyes, letting myself relax. I then realized I should probably not let Marvin do that, so I made the three of us lay down. I wrapped my arms around the German Shepherd, who wrapped his arms around Chris. I closed my eyes again, dozing off...

****

I huffed a little, pressing back up against Marvin, my pinned tail wagging as I close my eyes. This was pretty comfortable. I couldn't believe how comfortable his stomach got. It was soft, yet quite fluffy. I couldn't wait to cuddle up to it more. I opened an eye to look at the time, before I giggled, closing my eye again, before I heard a knock at the door. I sat up as best I could with Marvin's knot in me. I huffed a little.

"The door is unlocked."

I didn't care what the scene was, I was happy. The door opened, before I saw...Uh oh...

****

I looked down at Chris, not blinking as I narrowed my eyes. Was I seeing this right? Chris was...knotted by a fat German Shepherd? I saw arms behind the fat guy, but that wasn't important right now.

"Chris? Do you wanna explain this?"

He stuttered, unable to say anything. He could tell he was in trouble. I crossed my arms, before sighing. Then I saw the one behind the fat guy sit up. It was...Ryder?!
