It was a brisk day in late autumn, and school had let o	ut half an hour ago. The two boys were swinging back and forth on the swingset, almost perfectly out of sync with each other. The rest of their fifth grade class had already gone home, but on Thursdays, their mom was always late picking them up.

It had been a boring day and the brothers ran out of things to talk about rather quickly. Though the panda cubs’ wildly different coloring set them apart, it wasn’t hard to see that they were brothers.. and twins, at that. Where Kantra had blue-purple circles around his eyes, Cedar had light green ones. Where Kantra’s long purple headfur was brushed back, Cedar’s had a tendency to flop in front of his face. But other than that: they really looked similar. Both were a little short for their age, and despite their parent’s efforts, the two chubbiest boys in the class. 

That last fact was evidence of how alike they were in personality, too. They may have been brothers by birth, but they were best friends by choice. Kantra and Cedar loved all of the same things: the same shows, the same games, the same foods. And they both shared an aversion to team sports and a fondness for chocolate.

Even with as playful and energetic as they were, spending so much time together meant the occasional peaceful silence. And on an old swingset, feeling the chilly wind whip across their faces and watching solitary birds fly across an empty grey sky.. even for the rambunctious boys, a couple minutes of quiet was not unwelcome.

Till Cedar spoke up. “That guy is so cool.”

Kantra looked around. There was only one other person in the schoolyard, an otter leaned up against a brick wall, about a hundred feet from them. “Him? Why? Just cuz he’s in high school?”

There was an unspoken assumption that teenagers were cool, but that didn’t seem enough to remark upon. “No, dummy. Look.” As Kantra watched, the otter smoothly lifted a cigarette to his muzzle. The orange glow of ash briefly brightened. “See? He’s smoking. That’s so cool.”

Both their swings had come to a stop. “I guess it’s cool.” There was another moment of silence as they both watched the otter take another drag.

“Yeah, okay. It IS really cool,” Kantra relented. “We should try that when we’re in high school.”

Cedar looked over at his brother and grinned. “Why wait? I dare you to go over there and ask him for one.”

“What! No way!”

The green-and-white panda stood up. “Well, if you’re too chicken, then I will.” He started walking over toward the otter, before turning back around to his brother for one last taunt. “But I didn’t know you were such a little wimp!”

Kantra scrunched his face up and ran after Cedar. He wasn’t a wimp, but it was still a lot easier to do something like this with your brother as backup.

The otter saw the two chubby pandas walking toward them, and spoke up first. “What do you kids want?”

Cedar began, “We have a question to ask you..” 

and Kantra finished, “We want to try one of your cigarettes!”

The otter raised an eyebrow. These kids were clearly way too young to smoke. Lucky for the cubs, however, he had a real deep teenage rebellious streak. “Heh. You know these things are bad for you, right?”

Cedar crossed his arms. “I know. I don’t care; I still want to.”

“Fine, then. You can share.” The mysterious boy reached into his pack and pulled out one more cigarette. He put it into Cedar’s muzzle and pulled out his lighter. 

“Ready? Remember to share. And don’t wait too long before taking drags, otherwise the flame will go out and you better not come back to me for another light. Got it?”

They both nodded, excitedly. “Now inhale..”

Hot smoke filled Cedar’s little muzzle, but it was Kantra’s announcement that really got him excited. “You’re smoking, bro!”

The otter chuckled again. “He sure is, but next time.. inhale. Now get the hell out of here and stop bothering me!”

The two pandas ran back toward the swingset with their prize. They took turns posing with their stolen cig, trying to look as cool as possible, but it was Cedar that noticed that the smoldering end was turning grey.

“Kantra, it’s going out! You have to inhale it!” 

Steeling himself a little bit, the purple panda cub did as he was told. He sucked in his first mouthful of smoke and let it enter his lungs.. and immediately and violently started coughing. He passed the cigarette back to his brother, its flame reinvigorated, as he tried to collect himself. 

“Kantra?? Bro? What was it like??”

He was trying to talk about how terrible it was, but he couldn’t stop coughing. And when he finally did.. he felt really strange. Almost dizzy, but in a really good way. He’d never felt anything like it before. It was intoxicating! 

“Whoa,” was all he could manage for a moment. “You have to try it!”

Between the two of them, they smoked the whole thing down to the filter. The intense buzz powered them through the worst of the coughing fits. Not only did they look cool, but it felt so good, too!

They both wanted more. 

Kantra texted Mom and let her know that they were going to walk home, and they went right to the nearest drug store. The cashier was reluctant to sell a pack of cigarettes to young boys, but Cedar managed to convince him that it was really for their father who was VERY strict and.. he went on and on.

With their first pack of cigarettes in paw, the two panda cubs walked a few more blocks to the park. They found a spot that they’d been to before, hidden among the trees so no one could catch them, to rest their paws and smoke. They both lit up again and immediately began coughing, though not so violently as before.

As the buzz hit them again, the two brothers sat shoulder to shoulder on the mossy ground, leaning back against a fallen tree trunk. 

His voice a little hoarse from the burning smoke, Kantra spoke up first. “You know, that guy was right.. everyone says that cigarettes are bad for you.”

Cedar shrugged, ashing his smoke like he’d been doing it for years. “You ARE a wimp! I knew it!”

The panda cub pushed his chubby brother. “No I’m not! I’m DEFINITELY going to keep smoking! For way longer than you are, anyway!”

“No way. I’m gonna smoke a whole pack a day before we even get to middle school!”

“Whatever! I’m gonna smoke two whole packs every day!!”

“I’m gonna smoke so much, I’m just gonna smoke one after another after another so you can’t ever catch up to me!”

Kantra shook his head fiercely. “Then I’m gonna do that too!”

“No way. I’m gonna smoke forever. You’re gonna give up so fast, wimp! Even if it made me sick I’d keep doing it and you’d just give up like ‘Oh no, my heart!’” Cedar giggled, though it rapidly turned into a full-on cough.

“Nuh uh! I’d keep smoking no matter what! Even if it kills me!”

When his brother said that, Cedar felt his dick immediately go hard. Something about that thought unexpectedly and overwhelmingly turned him on. “Well, I bet I’m gonna smoke so much I’m not even going to make it to high school!”

Being cut from the same cloth, Kantra’s dick popped to attention too. He was super excited. “Well then, how about a bet? Last one alive loses! That way we REALLY know who wimps out on their smoking!”

Cedar’s dick was pressed hard against his tight school pants. “Fine! It’s a bet! And you’re going to lose!”

They both went to smoke even harder. Cedar closed his eyes to suck as much of the hot smoke into his young lungs as he could, when he felt his brother’s paw on his thigh. He opened them, and they immediately kissed.

They hadn’t really done anything like this before, but one of the best parts about having your brother as your best friend is that sometimes you don’t need to use words. You know how each other really thinks. And so there was no hesitation, no wondering if the other wanted to do something. They both knew immediately.

The kiss was hot and smoky and rough. The two panda boys made out furiously while undoing their pants and pulling their briefs down around their ankles. The ground was cold, but the smoke and their chubby bodies pressed up against each other kept them warm. Kantra’s paw started squeezing Cedar’s short dick hard as they kept kissing.. the green panda returned the favor. 

When the smoke in their kiss ran out, they kept pumping each other’s cocks.. but something was missing. Almost in sync, they lit each a new one. And instead of making out, they just smoked as hard as they possibly could, taking long drags as they filled their bodies up tar and nicotine. It didn’t take long for the two cubs to cum, both of their balls contracting at nearly the same time, excitedly pumping out burst after burst of cum onto each other’s bellies. 

Laying there half-undressed, they both immediately started coughing as hard as they could, desperately trying to catch their breath in between fits. Finally, Kantra spoke. “That felt.. so good.”

Cedar giggled. “Smoking rules..”

---

Though boys their age have a tendency to forget about these kinds of things rather quickly, neither Kantra nor Cedar were willing to let this one go. By the end of the first week, they had each managed to reach half a pack of smokes a day.

The coughing mostly subsided after the first few days; so did the intense buzz they got from smoking. It just made them smoke more. The first one out of bed in the morning would light up as soon as he could, waking up his brother with the thick, heavy smell of cigarette smoke. And the second that the burn hit one of their little throats, their boner would pop up immediately. It was an instant and perfect association. 

During recess, all of their friends thought they were cool when they whipped out their respective packs, pulled one out, and lit up. In fact, as the weeks passed and fall cooled into winter, they’d rarely do anything during recess except chain smoke for the full hour. Their spot, hidden from teacher supervision, was littered with dozens of cigarette butts.

The more that they smoked, the less anything else seemed to be important. Their friends invited them to play games, but they declined so often that they started being left out. They would bring their lunch outside and eat it with a cigarette between two digits. Instead of doing homework in the evenings, they’d watch TV and smoke until they got sick. If Cedar lit up a fifth cigarette before bed, Kantra had to light one up too.

Their grades dropped, but the cubs didn’t care. In fact, they were both almost proud of it. When an engineer came into the classroom to talk about his job and got the students thinking about what they wanted to be when they grew up, Cedar and Kantra could only grin at each other. They didn’t have to worry about that kind of thing. There was no way they were going to make it that far.

Or the time that they had a day of sex-ed in school, when they were taught about what their bodies were going to do when they entered puberty. How they’d start liking girls and how their dicks would get bigger and their voices would get deeper and they’re get more muscley instead of chubby. “Hey Cedar,” his brother had whispered, a mischievous grin on his face. “Guess that’s not gonna happen to you, cuz there’s definitely no way you’re gonna be around in two years, bro. Not unless you lose the bet. Hope you didn’t want a big dick that badly.”

This kind of thing happened all of the time, always with a sly smile and a boner.

“Hey, you know that movie you liked so much? They’re making a sequel.. too bad it’s not coming out until next year. Doubt you’ll be able to see it, bro.” 

“Mom said next year, we’re going to have Christmas at cousin Jay’s.. so glad we won’t be around for that.”

“You want to go down to the town center to watch them light up the tree? Probably be the last time you get to see that, bro..”

“Finished this whole pack tonight!! There’s no way I’m gonna last a year!”

They constantly smelled like smoke, and it was only a month before they were almost at two packs per day, a piece. The incessant, escalating smoke began to have some consequences on their little bodies. For one thing, they both entirely stopped growing. Both cubs seemed to be permanently stuck at just a little bit more than four feet tall, their growth forever stunted by the constant chemicals swirling through their young bodies.

Gym class began to become even more of a struggle. Both boys were already last in their class, thanks to their round, bouncing bellies and short stature, but when they could barely catch their breath after walking from one side of the gym to the other.. it became very difficult to keep up with their classmates.

It was only when Kantra was unable to catch his breath after a good five minutes of desperate, high-pitched wheezing, was he taken to the nurse. When he came back, he had an inhaler in one chubby paw and the biggest smile that either had ever seen.

Cedar was so jealous! Kantra was clearly smoking more than him, if he needed an inhaler already! But the sight of his chubby brother puffing from his inhaler in between long drags of his cigarette also really turned him on. In the locker room, while the rest of the class was off jogging and exercising, he took his brother’s short dick into his muzzle and started to suck on it. Kantra’s big white tummy pressed against his forehead as Cedar tried to get him to cum; he could smell his brother smoking and hear his raspy, uneven breath. When the purple panda’s little balls finally pumped cum into his brother’s muzzle, he was already sucking on his inhaler for dear life. As he tried to recover his breath, the green-and-white cub licked his lips. “No going back now, bro. You’re totally gonna smoke yourself to death.”

Still breathing hard from his inhaler, Kantra’s face widened into a smile.

Cedar needed another two weeks before he got his inhaler as well, after his gym teacher tried to motivate the lazy, addicted cub to jog a few yards. After that, they were fully excused from gym, and were able to spend that time doing what they wanted to do: smoking.

By the time the new year rolled around, both boys were north of three packs a day, with the goal of finishing a carton between them every day. They started to smoke more than one at a time to get the amount that they needed, often spending most of the evening smoking two after two after two.. always with their inhalers closer by.

With no homework to worry about and no sports they could play anymore, the brothers became even closer. After school and on weekends, they’d always just hung around naked.. smoking and watching television and eating candy. After all, if they didn’t have to worry about passing the PE test at the end of the quarter, who cared if they got chubbier?

It was one afternoon in late February that found Cedar sitting naked in front of his computer, idly tugging on the foreskin of his chubby, half-buried dick and smoking a cigarette. He began to speak, and his voice had gotten noticeably deeper and raspier. “Hey Kantra, we got an email from grandpa. He’s trying to be all serious, talking about how we’re the only boys in the family.”

The other panda cub was on the bed, also naked, playing video games. “So? Who cares?”

“He’s all talking about how we need to get married and have babies for the family name..”

“Like.. get married and have sex with a girl? Like in sex ed?”

“I guess so.”

Kantra giggled. “We don’t gotta worry about that, huh?”

“Hehe.. Yeah! There’s no chance we’re gonna live that long. Neither of us are ever going to have sex with a girl.” The unspoken assumption that went along with that was.. the only thing that either of their little dicks would ever attempt to breed was their chubby brother’s muzzle or paw. It turned Cedar on. “Hey bro.. can you suck it a little? I’ve been tugging but it’s not getting hard..”

Kantra paused his game and put out the remainder of his cigarette. “Course.” With ease, he slipped the limp little thing into his muzzle and started to suck. He heard Cedar moan, but after a few minutes, it still didn’t get hard. His brother looked up from between his thighs. “Maybe you need to smoke more? Try two or three?”

Cedar put another two cigarettes into his muzzle and lit them all. The triply-powerful smoke filled his lungs and brought with it a little bit of a buzz. It felt really good, and he could almost feel the tar filling him up. But his cock still stayed limp.

As his brother kept trying to firm him up, Cedar searched ‘dick can’t get hard’ on Google to see what the problem could be. After he read through a few pages, his eyes went wide. 

“Kantra!! Look!!”

“What?! What is it?”

The green panda was pointing to the computer screen, where he’d highlighted a passage. Top reasons why your dick doesn’t get hard.. and number one was crazy.

Heart Disease.

Cedar not being able to get hard actually meant that he was ruining his body faster than Kantra was!! Almost growling, he went back down on his brother’s limp dick, determined to get him hard. To prove that he wasn’t that bad off, yet. He did everything he could think of.. going all the way to the base of his two inches, playing with his little sac, rubbing his belly, squeezing his brother’s chubby butt.. but none of it worked. 

Determined not to give up his lead, Cedar finished smoking those cigarettes, and then lit up three more. He paid attention to his heart. He could feel it racing inside of his chest.. even though hormones were rushing through his body, his heart just couldn’t get enough blood to his dick. But eventually, Kantra’s tongue was able to coax out a weak little orgasm from his brother’s flaccid dick. Straining as hard as he could, and sucking three cigarettes down as hard as he could, his balls finally coaxed a few teaspoons of cum out. 
	
Kantra wiped his muzzle off. Even though he was jealous of Cedar, it was so hot that his brother had done this to himself. He had been pumping his own, regrettably hard, dick the whole time he was sucking his brother off. Knowing that his brother was smoking himself to death so fast. Knowing that neither of them would ever get married, or go to high school. How they were right now.. two chubby, smoke-addicted, panda cubs.. this is how they’d be for the rest of their short lives. He had already spilled his cum into his own paw by the time Cedar’s limp dick leaked out into his muzzle.

The panda cub kissed his brother’s muzzle, almost sucking the smoke right out of his fucked up lungs. All he could taste was ash. “Mm. I guess that’s it bro. That was the last time you’ll ever get hard. I can’t believe it..”

“Hehe. Yeah, heart disease sounds pretty bad, doesn’t it..?”

Kantra poked at his brother’s spent dick. “It sounds like you’re about to die any second! I can’t believe you smoked so much more than I have!” 

It was impossible to ignore how deep and raspy Cedar’s voice was, especially after having smoked half a pack of cigarettes in the last twenty minutes. “Just gotta catch up. Keep smoking.”

“I’m gonna.”

They were silent for a couple minutes; the only sound in the room was the faint whining wheeze behind each of the brother’s breaths. Finally Cedar spoke up, “Last day in February, bro. How about we go sit on the porch and have a couple smokes? Enjoy the sunset?” There was a grin in his voice, and they both knew what was unsaid: this is the last February sunset we’ll ever see. There wasn’t really any question, anymore.

They followed that plan and snuggled up really close on a bench outside. Kantra’s arm was wrapped around his brother’s chubby back; Cedar’s head rested on Kantra’s purple shoulder. Both of their bodies were soft and warm, and they watched it together, cuddled up close as they killed themselves just a little bit more with smoke.

====

As March came and went, it became impossible to ignore the effects the boys’ incessant and reckless smoking was having on their bodies. Their voices became almost unrecognizably raspy, as the smoke burnt its way through their fragile young throats. They would wake up a few times each night coughing their brains out, then smoke a cigarette or three just to calm down before passing back out. They had more and more trouble breathing.. when walking up a couple stairs, it was debilitating to the point of exhaustion, but even when just sitting there, shortness of breath was ever-present. The smoke had done so much damage to their lungs, filled their young bodies with so much tar that there just wasn’t enough room left for air.

And they just kept smoking.

Though they were still two very horny ten-year-olds, their bodies just couldn’t keep up with them anymore. Kantra’s cock went permanently and irreparably limp only a little bit after his brother’s, and it was becoming ever more difficult to get each other to cum. They just couldn’t get enough breath to ride it to completion! Their little hearts would be pounding a mile a minute, desperately trying to pump blood through beaten and clogged arteries to their hungry dicks and eager balls, but it was exhausting in the extreme.

To make up for the slight decrease in sex, they came up with other fun things to do. Sometimes, they’d just sit around, watching television and playing with each other’s foreskin and rubbing each other’s tummies. Other times, they’d cuddle up and one brother would watch the other play a game on their big TV, putting cigarettes to his muzzle to allow him to play uninterrupted, and they had to change spots if he stopped smoking even for a moment.

Some of their games had made them get even fatter. The pandas had never been thin, but their diet had become nothing but chocolate candy and cigarettes lately, and the empty calories were piling up on their rounding bellies and widening butts. One game they had a lot of fun with was simple: dump a whole bunch of candy on the ground in front of them. There was only one rule - you could only have a piece after you finished a smoke.

Both of them were comfortably at five packs a day, sharing a carton of cigarettes between them every single day. One hundred cigarettes a day, each. Almost half a gram of nicotine and two grams of tar for each of them, per day, every day. All of that tar went right into their struggling lungs; all of that nicotine went right to their brain, deepening their addiction.

And the fact that they were getting rounder and softer and fatter than ever didn’t really help their overworked hearts either. 

When final grades were announced in middle of May, both brothers had failed out of every course. Their parents were aware that their sons had started smoking and gave them several warning about its dangers, but they figured it was just a little phase. They had no idea that both Cedar and Kantra had developed a myriad of health problems from their obsession with smoke, so the boys decided it was better not to tell them that they had failed out of school and had to redo the year. After all, they reasoned, it’s not like they would be around in September.

And it was a good thing, too. Even though it was a bright, cheerful summer, the boys could barely waddle their chubby butts to the front door any more. They stayed in, ate and smoked themselves closer and closer to their last day. They were making good and sure that they’d never see their eleventh birthday.

Cedar was the first one to have his dick break; it made sense that he would be the first one to have his heart fail. 

It happened on a hot day, when both panda cubs were really horny. Drained of energy, they were pounding through cig after cig, pumping their respective little limp cocks and trying to get some semblance of relief. They went through a pack between then in twenty minutes, tugging furtively and uselessly at their broken little dicks. Straining and struggling, flexing as hard as they could. Their hearts pounded faster and faster, and Cedar’s vision went white just as he useless little cock twitched and started spurting. 

He clutched at his chest. He didn’t know what was happening at first, but he knew it was something with his heart. He wanted to smile at his brother, who was suddenly at his side. He spoke in his young, raspy voice. “K..Kantra.. I.. I think I’m having a heart attack.”

Kantra gave his dying brother another big, deep kiss. He could hear Cedar’s heart pounding rapidly and erratically as they made out, and finally came himself, covering his brother’s verdant, fat thigh with his watery cum. The intense kiss ended, but Cedar had already passed out. “Nice try, bro.. But not quite yet.”

It only took five minutes for the ambulance to come, and with lots and lots of drugs, they managed to save Cedar’s life. But it took five days in the hospital recovering: five days without a single smoke, without candy, without getting off. It was agony for the boy, who wanted nothing more than relief. Everyone around him was trying to save his life; all he wanted was to keep going. To push his body just a little bit farther, to smoke just a few more days before his heart finally gave up.

When he was finally allowed home, he could barely walk. Oxygen was constantly fed into his nose through a thin plastic wire, and there was a full face mask that he used often to catch his breath. And even with all of that: even the slightest exertion made his heart pound dangerously fast. He was under strict, life-or-death orders to NOT smoke.

Of course, that was the first thing he did when he was alone with his brother. He had an oxygen mask in one hand and a cigarette in the other, and the relief that came over his face when he sucked down that lung-scarring smoke was immediate. “Thanks.. bro..”

“Can’t believe you had a heart attack before me.”

“Yeah..” Cedar paused to take a few breaths from his oxygen mask. “I won.”

“Not yet.. you're still alive, after all.. but maybe soon, bro.”

Before he could ask what Kantra meant, his brother came right up to him and kissed him again. The purple panda’s paw went right to his limp dick and started tugging. “What do you think?”

“I.. I don’t think I can survive it,” said Cedar. He was so turned on, but his dick just lay there, uselessly.

“I know, bro. Ready for your last cum? To win the bet?”

The ten-year-old took a deep drag of his cigarette, then dropped it. He could only wheeze. “I’m ready to win. Kill me.”

Kantra started to pump his brother’s soft dick, even though the little thing was almost buried in chub. He sucked in as much smoke as he could from his own cig, then kissed his brother. As he pumped away, he exhaled fully into his Cedar’s scarred lungs. The nicotine and tar hit his system immediately, and his heart started thumping hard.

He repeated this over and over as he jerked his brother off. “I can’t wait to take your last load into my paw, bro. It’s gonna be all mine.” Another drag, another kiss. “You’re never gonna see mom or dad ever again. It’s just you and me forever. You’re never gonna grow old. Never gonna fuck anyone. Never have babies.” Drag, kiss. “And you’re gonna win the bet.”

The went on and on, for almost a full pack. Kantra kept breathing hot, noxious smoke into Cedar’s body, making his heart panic. It became erratic, and Cedar began to wheeze and gasp dangerously. “D.. don't stop, bro..”

He was almost there. His brother was dying in his arms, and Kantra knew he was only a couple weeks behind him. This was the end result of their dare, what they had done to each other. Made sure that their lives were cut brutually short before either of them could even enter middle school. Cedar would never turn 11, and Kantra was going to be right behind him.

Just then, Cedar’s soft, impotent little dick burst. His sac contracted as balls pumped the last of his life out into his brother’s waiting paw. His vision faded, and his brother kissed him one last time. 

“You win, bro. But I’m right behind you.” 

The last thing Cedar saw before he died was his brother sucking the same cigarette that killed him down to the filter.
