Filling Their Brothers
By WaffleSquadron

“Where did you even meet these people?”

Kyle was pacing across the living room, his dark tail hanging limp behind him, ears flattened against his skull.

“I told you: I talked to them online. It’s gonna be fine; they are just like us!”

The young german shepherd boy was bouncing in his seat, pregnant belly stretching out his t-shirt. 

“Cody, I really don’t think this is a good–”

A sharp rapping against the apartment door cut him off. Cody hefted himself off the sofa with a grunt, holding his arms out to balance his ungainly form. He hobbled across the floor, Kyle chasing after his pregnant brother the whole way. 

Cody flung the door open, revealing a pair of dalmatian boys standing in the hallway. They were obviously related; their unique fur color was impossible to miss. The older boy was a few inches taller than Kyle and was covered in blue and purple spots. The younger cub was a near carbon copy, standing roughly the same height as Cody and sporting pink and green spots. 

“You made it!” Cody was grinning ear to ear, practically dancing as his foot paws refused to keep still.

“Uh… hi…” the younger dalmatian said. He was holding onto his brother’s arm, half-hidden behind the teen so just his colorful ears and spotted face peeked past.

“Wh-who are your friends?” Kyle asked, his lips pursed and tense.

“Heh, you must be Kyle,” the older dalmatian said. “I’m Adam, and this is my brother Jake.”

Pushing his brother between the shoulder blades, he eased the smaller cub into full view. Jake waved, offering a shy smile, but all eyes were on his belly. There was no mistaking the familiar rounded swell in the front of his loose shirt, and the way he cradled his midsection with his paw.

“You’re pregnant!” The words tumbled out of his mouth and Kyle groaned silently to himself.

But Adam’s face didn’t change. He let out a quiet snort and said, “From what Jake tells me, we have a lot in common. Mind if we come inside?”

Kyle nodded, his muzzle hanging slack as he ushered them into the small apartment. Adam patted him on the shoulder as he strode past. Jake stayed glued to his brother, keeping one paw wrapped around the older boy’s arm and the other supporting his belly. Cody followed close behind, a slight waddle in his step as he worked to balance the growing weight of their cub.

“Mind if we sit down?” Adam asked. “I don’t like making Jakey here stay on his feet for too long.”

“Uh yeah, sure,” Kyle said, motioning toward the couch. 

“I’m not helpless; you don’t have to treat me like a little kid,” Jake said.

“You love it when I do, though,” Adam said, giving the younger boy’s rear a squeeze.

The dalmatian boys took a seat and Cody plopped down next to Jake, staring intently at the spotted boy’s stomach.

“So, uh, how did you guys meet Cody? Is there some support group I don’t know about?”

“Not quite,” Adam said. “Don’t know any ‘Pregnant Brother Awareness’ programs. Jake started talking to him online.”

A big smile stretched across Jake’s muzzle. “Yeah! I really loved his story. It was like someone wrote about our lives. I was almost worried he was spying on us or something. But I sent him a message and we started talking, then it just kinda went from there.”

“His story? What story?,” Kyle replied. “Cody, what are they talking about?”

Cody grinned a wide, toothy smile, but his drooping ears betrayed him. “Hmm? Oh, it’s nothing… I was just kinda messing around and sorta posted this thing…”

“It’s really great!” Jake said. “The part where they tie for the first time and start kissing is my favorite.”

“Wait, is this story about us? Cody, what were you thinking!” Kyle’s eyes went wide, his breaths coming in shallow huffs as he glared at his brother.

“I’m not stupid! I didn’t use our real names. Besides, this was kinda your idea anyway. You said that none of those stories on the internet are real. So I wanted to make one that was.”

Adam cleared his throat. Placing a paw on Jake’s back, he said, “How about you guys go check out Cody’s room? Let the big brothers have a little chat together.”

Cody heaved himself off the couch, taking a moment to steady himself. “Yeah, I can show you the next chapter I’m working on!”

With a little assistance from his brother, Jake stood up too. The two younger boys disappeared down the hallway, chatting together like old friends.

“How far along is he?” Adam asked. He was looking over the back of the couch, eyes focused on his brother the whole time.

“Uh… we’re not sure, but probably five months.”

“Jake’s around six. It’s a lot harder to hide now; baggy clothes only do so much. Dark colors help a bit though.”

“T-thanks,” Kyle said. “It’s weird talking about this stuff with someone else. But it’s nice too, not having to hide from everyone.”

“Trust me, I know the feeling. When we realized Jake was pregnant… well it felt like the world was ending. But now, I can’t wait for our pup to be born.”

“So it's your… I mean you and Jake…”

“It’s my cub,” Adam replied. “I told you; we have a lot in common.”

“How did you guys… I mean, with Cody and me, it was almost an accident the first time.”

“I know,” Adam said with a chuckle. “I read the story, remember?”

Kyle slapped a paw across his face and let out a long groan. “I can’t believe he posted that online…”

“It’s fine. Pretty sure nobody else thinks it’s real. Whoever heard of a boy getting pregnant, anyway?”

“I know, but…” Kyle sighed. “No point worrying about it now.”

“But to answer your question, Jake was actually the one who started it.” Adam shook his head, and looked off into the distance. “One night, he just crawled into my lap, planted a kiss on my muzzle, and started rubbing himself against the tent in my pants. I was powerless to resist.”

“Whoa… how old were you guys?”

Adam cocked his head to the side. “That was… two years ago? So he was ten and I was fourteen. Feels like a lifetime, though.”

“What about your parents? Do they know yet?”

A sudden coldness crept across Adam’s face. The easy smile on his muzzle faded and his ears swept back against his head.

“I didn’t mean to pry–”

“It’s fine,” Adam replied. “It’s just our Dad. But… he doesn’t get a say. Jake and I have each other, and that’s all that matters.”

 The dark clouds hanging over the older boy seemed to part as soon as he said his brother’s name. “I love that little guy more than I ever thought possible.”

“Speaking of little brothers,” Kyle said. “They’re being a little too quiet, don’t you think?”

Adam cocked his head to the side, raising his ears and straining to listen down the hall.

“Never a good sign. Wanna see if we can catch them in the act?”

"So this is it. I know it's nothing special but–" Cody said.

"No way!" Jake cut in. "I can't believe I'm in the actual room!"

The twelve year old stepped gingerly across the carpeted floor. His fingers trailed across their shared desk, pads barely making contact with the wood. He stopped just before Kyle's bed and let out a quiet gasp.

"Is this it? Where you two tied for the first time? Where he got you pregnant?"

"Well… kind of…" Cody replied. "I took Kyle's knot for the first time here. But I might have taken a little bit of artistic license with the rest."

"Aww, really? But that was so romantic…"

"I know…" replied Cody. His eyes swam with a momentary, dreamy recollection. "I'm pretty sure that's when I got pregnant but there's no way to tell. It could have been on my bed, or in the shower, or the living room couch, or this one time on the kitchen counter…"

Jake let out a loud snicker. "You guys are crazy! I can't believe your parents never caught you."

"I know it sounds wild, but I have to beg Kyle to do stuff most of the time," Cody said. "What about your brother? What’s he like?”

“It's just me and Adam most days. So we don’t really have to worry about getting caught at home.”  A goofy smile stretched across Jake’s face and he stared aimlessly toward the far side of the room. “And Adam is… he’s the best brother in the world.”

“How big is his weiner?” Cody asked. 

“Wh-what? I mean… umm…” Jake stammered. 

“I’m just teasing,” Cody replied, with a giggle. “But he is a little taller than Kyle, so I am kinda curious…”

“I don’t think we ever measured but he’s pretty big. It feels like he’s poking me in the stomach sometimes,” Jake said. His pink and green ears were practically crimson on the inside, but his tail was still wagging.

“But I think his tongue is even longer,” Jake added. “Have you guys ever done a sixty-nine?”

Cody tilted his head to the side, ears raised and attentive. “No? What the heck is that?” 

“Oh! That’s when you like, lay top to bottom and you suck his weiner and he licks your… you know…”

“Pussy?”

Jake’s ears blushed again and he nodded.  “It’s really fun, you should try it.”

“Maybe we could try?” Cody replied.

“Huh? Us? But that’s not what–”

“Yeah we could, you know, lick each other,” Cody said. “I’ve never really done stuff with anybody except Kyle before. And I kinda want to know what it’s like with another boy that’s, you know… like me.”

A big grin stretched across the dalmatian boy’s face and his tail started wagging. “Hmm… That does sound pretty fun.” 

Cody didn’t waste any time. In a flash, he was tossing his shirt across the room and flopping down onto the bed to pull his pants off right after. In only a few moments, he was peeling his white briefs down his legs, exposing his tan belly and dark, puffy spade. Leaning back on his paws, he looked up at Jake expectantly.

Jake was a little slower, peeling his shirt off to expose his pregnant belly. Cody giggled when he noticed the pink and green spots extended all the way down his front, his baby bump stretching a few out. Taking care to maintain his balance, Jake leaned forward and slid his pants down, showing off a pair of blue panties underneath. Cody’s eyes widened, but he didn’t say anything. The older boy slipped the thin fabric down his legs as well; then Jake stood up straight, exposing his swollen white furred spade.

“Whoa…” Cody gasped. “You look really cool…”

Jake’s tail curled between his legs and his eyes darted to the floor. “T-thanks. Umm… I’m not used to other people seeing my… thing.”

“I know what you mean,” Cody replied. “But it’s really cool seeing another boy like me.”

“Did you want to, you know, get started?” Jake said, dragging his foot paw against the carpet.

“Sure! What do we do? You’re the expert here.”

“It’s pretty simple,” Jake said. “We just lie down in opposite directions, and you know… make each other feel good.”

Cody nodded and scooted back on his bed, laying on his side and propping one leg up to expose his privates. His heart pounded in his chest as Jake climbed onto the other side of the small mattress, walking on his knees toward the center before laying down in the other way. Pink and green spots danced before Cody’s eyes until his eyes focused squarely on the puffy canine pussy right in front of his face. 

It was familiar but strange all at the same time. So much like his own, but almost opposite as well. While his spade was dark and surrounded by thick tan fur, Jake's pussy had a few stray spots along the edge, but the rest was a pale pink that just barely showed through the thin white fur. The Y shaped lips clenched, and a thin sheen of arousal leaked out. Then he heard a soft cough from the other boy.

Cody glanced down, but couldn’t see past the pair of pregnant bellies in the way. Leaning up on his elbow, he looked at Jake.

“You can lick me whenever.”

“S-sorry,” Cody replied. “I was just… looking. I never saw a pussy before, except my own. I’m glad we’re doing this.”

“Oh just wait,” Jake replied. “It gets so much better.”

He dropped his head back onto the mattress and Cody felt a warm, wet swipe across lips. “Oh!” Then another. “That feels…”

He quickly lost track of where one lick ended and another began. Pleasure shot up his spine as Jake went down on him. With the last of his self control, Cody flopped onto the bed and stuck his muzzle into the spotted spade in front of him, doing his best to return the favor.

As it turned out, that was much harder than it appeared. As soon as Cody’s tongue made contact with Jake’s pussy, the boys’ pregnant bellies bumped into each other.

“Sorry,” Cody said.
“It’s ok,” Jake replied.

Cody went right back to work, doing his best to press his snout into Jake’s lower lips. That smushed their baby bumps together even tighter, and he was barely able to lick across the very tip of the dalmatian’s spade. That one lick was tantalizing nonetheless. The feel of soft heated sex against his tongue drove the young pup to search for more; the mild sweetness and salty tang danced across his tongue, demanding he taste more.

But as much as he wanted to, their position was awkward at best. Never one to give up easily, Cody kept at it, dragging his tongue across the pale pink pussy, doing his best to squeeze inside those heated folds and tease the older boy’s clit. But the more he pushed himself, the harder their bellies pressed together.  Worst of all, the more Cody stretched forward to lick Jake, the more he pulled his own needy pussy away from the eager tongue servicing him. After no more than a minute, a sharp kick from the inside of his womb stopped Cody in his tracks.

“Oh!” he said, placing a hand against his side. “Pretty sure that was a protest. I don’t think he likes getting all squished.”

“Yeah,” Jake said, pulling his muzzle away as well. “Sorry, I guess a sixty-nine doesn’t work so well if we’re both pregnant.”

“It felt good though,” Cody said. “Maybe we could take turns instead–”

The sound of the doorknob rattling cut him off. Both pups froze, heads snapping to watch the door click then slowly swing open. Clucking tongues echoed from the pair of shadowed forms in the hallway.

“What did I tell you,” came Kyle’s voice. “Cody’s never this quiet; they had to be up to something.”

“I’d say they were going down on something,” added Adam with a smirk.

The two teens walked into the room, shutting the door behind them. Kyle was shaking his head and paw pressed against his forehead.

“Are you trying to get us into even more trouble?” Kyle said. “It’s bad enough the two of us do stuff, now you’re fooling around with another boy?”

“It’s not Cody’s fault!” Jake cut in. “It was my idea! We were talking about you guys and I mentioned how Adam and I lick each other and–”

“And it’s not like anybody else is home!” Cody cut in. A wicked grin stretched across his muzzle before adding,  “Besides, if it’s so wrong, then why can’t you stop staring?”

“Uh well…” Kyle replied, not taking his eyes off the cubs. “That’s just… You know, because it’s–”

“Hot,” Adam said. “I’ve never seen Jake with another boy and I gotta admit, I like it.”

“Really,” Jake asked. He rolled up into a sitting position, his eyes shining. “Did you want me to do more?”

“You should do it with Kyle,” Cody said. “His knot feels so good when it locks inside you.”

“Cody! No…! I can’t–” Kyle said, suddenly shrinking back.

“It’s ok,” said Cody, sitting up on the bed. “I want you to.”

“You… you do?” Kyle asked, his head cocking to the side. “But I don’t want to cheat–”

“It’s not cheating if I give you permission, stupid. And besides, Jake is pretty cute, isn’t he?”

Kyle glanced over to the dalmatian boy, whose ears were flat against his head while simultaneously spreading his legs to give a clear view of his pussy.

Cody added, “And I kinda wanted to try doing it with Adam…”

A small twinge of jealousy gripped Kyle. The idea of another boy being with Cody, with his brother, set his hackles on edge. But only for a moment. There was no doubt they were mates, the boy was carrying his pup afterall. This was just a chance for both of them to explore a little..

“You know,” Kyle said. “I think that does sound like fun.”

“You don’t have to twist my arm,” Adam said. “Cody is the second cutest cub I’ve ever seen.”

The older dalmatian started undressing right away, revealing that his blue and purple spots went all the way down as well. 

“Sit on the other bed,” Cody said. “I wanna try something.”

“You’re in charge,” Adam chuckled, taking a seat on the edge of the bed. 

Pulling his boxers down, he spread his legs open and waited. Cody sauntered over, eyeing up the thick spotted sheath and the two inches of bright red shaft poking out from the top. 

“Whoa,” Cody whispered, his breaths becoming a little deeper.  “Stay right there.  I know just what I want to do.”

Cody spun around, smacking Adam in the face with his bushy tail before lowering himself into the older boy’s lap.  He reached down and grabbed his sheath, pulling the loose skin down and exposing even more of the teen’s cock.  Adam tensed up, before letting out a long, low groan as his tip caught the middle of Cody’s folds.  The young cub’s slick sex spread easily around the his cock, stretching open as his sheath was peeled back all the way.

“Oh fuck, you’re so tight…” Adam grunted.  “I’m not sure it’s all gonna fit.”

“Mmm… you’re not leaving this room without knotting me,” Cody replied, sinking his hips even lower.

It only took a few seconds until he felt the top of Adam’s soft knot at his entrance.  Without missing a beat, Cody dropped himself completely into the teen’s lap.

“Mmmm… now that feels good…” Cody moaned.  “I wanna feel your knot tie me nice and tight.”

“Y-you’re not going to have to wait long…” Adam gasped.

Sure enough a few heartbeats later, Cody felt the cock inside him start to throb and expand.  The dalmatian’s impressive sheath hid an equally impressive dick, leaving Cody  moaning and grunting as the teen’s large knot inflated bigger than he’d ever felt before.

“Oh fuck… Oh fuck!” Cody whined. “Start moving… I need you to fuck me!”

Adam wrapped his arms around the young shepherd and started thrusting into him like his life depended on it.

On the other side of the room, Kyle had just kicked off the last of his clothes and was doing his best to keep his paws from automatically covering his tan sheath.  He sat down next to Jake, swallowing hard before asking, “So… what did you want to do?”

“I like to be on top,” Jake said.  “Don’t worry, just sit back and I’ll take care of everything.”

The young dalmatian climbed onto Kyle’s lap, his tail wagging like crazy the whole time.  Reaching down, he used two fingers and spread his lips open wide before lowering himself onto Kyle’s waiting sheath.  A few inches of pink cock were peaking out and Jake wasted no taking him inside.  With a practiced ease, he speared himself onto Kyle, gasping as his pussy stretched around the thick cock.

“Mmm… You’ve got a nice one,” Jake said.  “I bet your knot is gonna feel awesome.”

Kyle barely managed a groan in response.  He’d never been with anyone but Cody before, and he was still adjusting to the sensation of another boy’s pussy wrapped around his cock.  Jake was a little bigger than Cody, a few pounds heavier and about an inch taller, but his pussy was so snug and warm he could barely keep his eyes from crossing.  He groaned as his knot expanded, locking them together. His paws naturally grabbed onto the spotted boy’s rear, gripping Jake’s cheeks tight as the young pup began to ride him.  

“Oh yeah, oh fuck… I can’t believe I’m actually doing this,” Jake moaned.  

His hips rocked hypnotically, tugging at Kyle’s straining knot and spurring the shepherd boy to hump against him, and drive his cock deep inside that exquisite canine pussy.  The colorful spots on Jake’s baby bump danced in front of his eyes.  Looking up, he was transfixed by the look of bliss on the cub’s face as bit his lip and moaned.  Kyle had no doubt Adam was telling the truth about Jake seducing him.

Glancing over to Adam, the breath caught in Kyle’s throat. He watched in shock as the dalmatian boy fucked his pregnant brother.  Cody’s eyes were rolled back in his head, and his belly swayed in front of him, as the older teen pounded into him like a machine.  Maybe he should have felt jealous, but Cody looked more beautiful in that moment than he could ever remember.  The bliss on his face was clear as day and Kyle could not tear his eyes away.

“I’m getting close, little guy,” Adam groaned, his muzzle pressed against Cody’s ear.

“Me too…” Cody moaned. “Rub my clit, I wanna cum with you…”

Adam’s paw pad locked onto the pointed tip of Cody’s spade, rubbing in tight little circles around his sensitive nub.  The younger boy squealed, tossing his head back as his chest heaved uncontrollably.  

“Oh fuck, oh fuck!” he yelled, falling over the edge.

Adam gasped as the already tight pussy clamped down around his cock.  Without warning, his orgasm crashed into him, rolling over him in waves of pleasure as he spasmed and fired off jet after jet of seed into the young shepherd cub.

Seeing that was all it took for Kyle to reach his peak.  The second he heard Cody’s familiar wail of orgasm, his climax welled up from deep inside, his knot stretching Jake’s pussy even wider than before as he hugged the spotted pup against his chest.

“Ugh! Oh fuck!” Kyle grunted.

Jake gasped as the unmistakable warmth of Kyle’s cum burst inside him. The slick heat filled his entire lower body, throwing the dalmatian boy headlong into a wild climax.  He wrapped his arms around Kyle’s neck grunting as spasms wracked him from head to toe.  

Minutes passed as the boys recovered, still tied together. Loud huffs and low grunts were all they could manage for a good while.  Finally, Adam sat up on the far bed, holding Cody’s back against his chest.

“Now that… was a lot of fun,” he panted.  “What do you say we do this again sometime?”

“Mmmm… I would like that…” Cody moaned.

“Heh, maybe I can even give Cody here his next cub. Maybe we can trade and you can put a puppy in Jake.  What do you say?”

Kyle’s head shot up to glare at Adam.  But a quick wink from the older teen quickly melted his outrage.  

“Sorry, Cody’s all mine,” he replied. “But… I wouldn’t mind swapping brothers again.”
