Lewd Teachings

With the tip of his tongue poking out the side of his muzzle in concentration, Koi’s eyes focused on the soccer ball, the stout furred dragon taking a few steps back to wind up before sprinting towards it, his pink fur blowing in the wind as he kicked the ball with all of his might, letting out a hard grunt. With a cocky smile, the hatchling watched the ball careen through the air and towards the goalkeeper, sailing right past the other boy even as the goalie tried to dive for his kick, the ball smacking into the net as Koi pumped his fist with a victorious roar, 
“Yeah, take that!”
Sitting in the sidelines of the small grass field was the 10 year old dragon's brother, Tuna, shorter by a sliver even though he was almost two years older. The blue-furred dragon was barely paying any attention to the cheering and shouting coming from the makeshift soccer pitch, his eyes glued onto a book he was flipping through, sitting back under the shade of a tree as he sighed quietly. Koi had always been the more outgoing one of the pair, having easily made friends the moment the two hatchlings had been brought to their new home at the orphanage when they were still very young. Tuna on the other hand enjoyed his privacy and silence a lot more, happy to just stay cooped up in their shared bedroom and study for hours, if it wasn't for his younger brother always dragging him away to do something. The furred dragons had always been very close, barely ever finding one without the other being just a few steps away, even if their personalities were nearly polar opposites. 

Scanning the pages of his book, Tuna slowly felt his focus starting to slip, staring at the words blankly, continuously having to go back and reread what he'd just gone through as his mind fogged up, suddenly unable to find a comfortable position to sit as he fidgeted and squirmed. It wasn't the noise of the football match that was keeping the boy unfocused however, it was something a whole lot more embarrassing, the cub quickly realising that his shorts were starting to tighten all on their own, glancing down to see a small bulge starting to form on the front of the pair. With a red face, the dragon quickly folded up the page to mark where he'd left off as he pushed himself up to his feet, keeping his book directly in front of his crotch as he turned to leave, waddling back towards the dormitories when his brother shouted out for him, 
“Hey, Tuna, where are you going!?”
Glancing over his shoulder, the flushed cub cleared his throat, seeing his little sibling jogging to catch up to him, the football tucked under the pink dragon's arm, 
“I'm… just… heading back to our room, too hot to read out here.”
Koi scoffed, 
“Hot? I'm the one running around while you're sitting on your butt, and I'm barely working up a sweat.”
“Well… I dunno…”
Tuna kept walking, getting a sigh from Koi as the younger of the pair tossed the soccer ball to the rest of the boys, grabbing his backpack from a bench and walking with his brother, 
“Guess I'm heading back too.”
“You know, you don't… have to stick with me all the time. I just mean… maybe… I don't mind spending a few minutes alone, you know?”
Koi shrugged, 
“Nah, it's boring out here without you anyways.”
Sighing, his little sibling seemingly determined to follow him, Tuna tried to plan how he could hide his unplanned erection until it'd go away, not keen on having the brash cub spotting him in such an embarrassing state. 

Walking through the orphanage at a brisk pace, his eyes mostly fixed on the floor to try to hide his red cheeks as he found himself suddenly getting quite envious of his brother's pink fur, Tuna hurried towards their shared bedroom, keeping his arms down in front of him at all times. The boy's nervousness worked against him, the rush of blood as he marched through crowds of other kids keeping his manhood stiff in his shorts even as he bit his lip and groaned under his breath, just hoping it'd go away before anyone noticed. As soon as he'd made it into their bedroom, Tuna sat down on his bed, quickly pulling his blanket over his lap as he set his book down, letting out a relieved sigh, though just a moment too early. Koi raised an eyebrow at his big brother's odd behaviour, finding it odd even with him already rather used to the blue dragon's quirks, 
“You were hot just a minute ago outside, and now you're cold enough to need a blanket?”
Scrunching up as he looked away from the younger boy, Tuna tried to come up with some sort of an excuse, though he was already too late, his suspicious brother grabbing the corner of the blanket and yanking it off with a devious smirk. Yelping, the hatchling immediately bent over to cover up his crotch, his face almost as red as his sibling's as the other dragon snickered, 
“Oh, I see what's going on, you've got a boner, don't you~?”
“A wh… what?”
Koi laughed, 
“You know, when your thing gets hard. You haven't heard of a boner?”
Feeling even more embarrassed, Tuna didn't want to admit that he indeed had very little idea about what his little brother was talking about. 

Being a late bloomer, the hatchling had only recently had to begin dealing with his dick stiffening up out of the blue, all around the day and utterly at random. The boy didn't know much about sex, besides that it was embarrassing to even check out a biology book about it from the library, let alone actually talking about it with anyone. Thus, he'd just kept his recent awkward issues a secret from everyone, having noticed that they tended to go away on their own, though it occasionally took quite a while to do so. What Tuna didn't know however was why the furred dragon two years younger than him seemed to be so much more knowledgeable about such a topic. Spotting the discomfort on his older brother's face, Koi giggled and tried to peek under Tuna’s hands to get a glimpse of what the other dragon was packing, getting to bask in the rare moment of him actually knowing more about something than the little bookworm he always dragged around with him, 
“Heck yeah, looks like this guy finally knows something you don't! What's the matter, your books don't talk about the birds and the bees~?”
Groaning and rolling his eyes, Tuna had to admit that his sibling had him beat for once, though he was more eager to actually put that knowledge to use rather than just having the cub gloating at him all day long, 
“Alright, yeah, I don't… really know a lot about… this sort of stuff. But… you do?”
Putting on a big grin and standing tall, his hands proudly at his waist, Koi nodded, 
“Oh yeah~!”
“So you've like… been with someone?”
Koi’s smug smile immediately died down, 
“Well, I mean… I know about it and everything…”
“Okay so… when does it go away? How can I make it go soft again?”
Tuna moved his hands away from covering up his crotch, letting his snickering little brother take a peek at his tented shorts as he gripped the side of the bed with a heavy blush, hoping that the pink dragon wouldn't just giggle at his situation, 
“Well, there is a way…”
“Really? What is it?”
“It's actually kinda fun, but… you're gonna have to trust me~”

Though he wasn't sure he liked the sound of what the mischievous furred dragon had in mind for him, Tuna was desperate enough to get rid of his awkward erections to try just about anything, giving a soft sigh before nodding as his brother smiled, 
“Alright, first up, you gotta get naked.”
“What? No!”
Groaning with annoyance as he stared down his cross armed big brother, Koi rolled his eyes, 
“C'mon, do you wanna do this or not? Look, it's no big deal. Heck, I'll even go first!”
The pink cub grabbed his pants, yanking the pair down to his ankles and stepping out of them before likewise dropping his undies right after, showing off his sheath and sack with a flourish, his manhood still soft unlike his sibling's, 
“Ta-da! See? I'm still here, so just take your pants off already!”
Giving a shy groan, glancing at his little brother's goods while trying to make it look like he was just staring at the ground, Tuna followed the other hatchling's lead, opening up his shorts and pulling them off along with his briefs, leaning forward slightly and squeezing his legs together to still try to hide his cock even with his pants off, the tip poking out from between the fluffy fur on his thighs. 

With a small chuckle at just how flustered and squirmy the otherwise calm little dragon was getting, Koi sat down next to his big brother, leaning back on one of his arms and spreading his legs, his knee bumping up against Tuna’s. With a long, drawn out exhale, the boy wrapped two fingers around his sheath, gently rubbing on it with half-lidded eyes, both dragons watching close as his tip began to peek out of his sheath. Grabbing his shaft as soon as it was out, Koi began to slowly and gently stroke on it, letting it grow in his hand until he was at full mast, a tiny bead of precum glistening at the very tip of it. Wiping off the pre and licking it from his fingers, Koi turned to his brother, 
“See how it's getting all big and stuff? Now that it's hard, the only way it's going down is if you wait a bunch of time, or if you cum.”
“I… if you… what?”
“You cum. You just basically do what I did for a while, and you… well, I dunno how to really explain it, but you just kinda shoot out this goo, and it feels good, then it just sorta goes soft all on its own.”
Koi reached for his big brother's legs, pulling them open as the smaller dragon gave a surprised yip, leaning back to let him demonstrate, even if a little nervous still. Moving the blue-furred cub's legs out of the way, Koi eyed up his sibling's shaft, slightly disappointed to see that they were both almost the same size down there, having hoped that he'd reign victorious over both their heights as well as their lengths. Not trying to waste too much time comparing their manhoods, Koi pinched his brother's cock between his index and his thumb, sliding them up and down the entire cock at the same rhythm as he was stroking himself.

Gasping softly as soon as his little brother's fingers wrapped around his dick, involuntarily scrunching up with his legs slamming together, Tuna moaned quietly as the other boy jerked him off. He wriggled around on the side of the bed as he wrestled with the new sensations washing over him, the weird yet pleasurable mix of tingling and tickling making his tail twitch as he panted at the same time as the younger hatchling explained what was going on, 
“This is called jacking off, you just sorta rub it with your fingers. Try it!”
With Koi letting go of his shaft, Tuna took a second to catch his breath before quickly emulating the other cub's grasp, pumping at his dick at a rapid rate while continuing to moan. Feeling his fingertips getting wet as he stroked, Tuna looked down to see clear and slick liquid oozing from his tip, having some difficulties getting words out of his mouth with his heavy breathing, 
“Wh… what's this… stuff?”
Koi let go of his own cock, swiping up a glob of precum and smearing it between his fingers, letting the thin strands stretch out between his digits as he opened his hand, 
“It's called pre, I'm pretty sure. When you keep doing that, something kinda like this comes out at the end, though it's all white and sticky, and there's a bunch more of it.”
Trying his best to hold back his moans, Tuna kept jerking off all through his brother's explanation, 
“S… so, when does… that happen?”
“Well, it can take a few minutes, kinda depends. But… there are a few ways to cum faster than just with your own hand~”
“What's that?”
“I can show it to you, but you gotta do everything I tell you to~”

Though he felt a slight pang of shy hesitancy in the back of his head, Tuna had to admit that the trick that his brother had already shown to him felt great, feeding into his curiosity about discovering more. With a small huff, the dragon nodded, 
“Alright, but this better not be a prank or something!”
“It's not, I promise~”
Koi hopped off of the bed and knelt down in front of his brother, one hand on the smaller cub's knee as he opened his mouth and stuck out his tongue, giving the fellow dragon's stiff and throbbing shaft a few quick licks. Immediately tossing his head back with a loud gasp, jolting from the shock of intense pleasure unlike anything he'd felt before, Tuna quickly pushed his sibling's maw away and clamped his legs together, letting out a shuddering moan,
“G…geez, you gotta warn me first!”
Giggling, Koi let his brother take a quick breather before he pushed his snout back down into the blue dragon's crotch, going slightly gentler this time around. He cupped his tongue around the underside of the other boy's girth, slowly sliding it up and down as Tuna whimpered and moaned, a small pool of precum gathering onto his tongue. Based on the way his older brother was panting, Koi could guess that the hatchling was getting quite close to cumming as he continued working over the shaft, softly lapping at it while Tuna laid back on the bed, squirming around and trying to endure the intense licking. Koi however didn't intend to get his brother off with his maw, having an ulterior motive to what he was doing, smirking as he licked the dragon within an inch of an orgasm. 

Taking his brother right to the edge, as far as he thought he could, Koi suddenly pulled back from the moaning hatchling's cock right before the other boy came in his mouth, quickly wiping the drool from his lips as Tuna stared up at him, a panting and whimpering mess, 
“Wha… why’d you stop!?”
Fondling his own dick, the pink dragon sat down next to his sibling, grinning as he eyed up the cub's rump, 
“I haven't shown you the final way to get rid of a boner yet, the best way~”
“Th… there's a third way?”
“Yeah, and it's the most fun one~”
Though he wasn't about to admit it to Tuna, Koi had hoped to get his brother desperate enough so that he'd finally be allowed to try out something, an act he'd wanted to do ever since finding it on the pages of a smut magazine stashed in a bush on the orphanage grounds. The cub's plan was working perfectly, with Tuna hovering right at the edge of his first climax, his entire body quaking as he whimpered, desperate for relief, unable to say no to something that was supposed to feel even better than the licking. With a needy whine, the blue dragon nodded, obediently doing what his little brother wanted as Koi rolled him over onto his belly, getting him up on all fours, 
“It's gonna feel a li'l weird at first, but then it'll be really good~”
Koi knelt behind his sibling, moving the bushy tail out of the way and spreading Tuna’s ass cheeks apart, staring at the tiny pucker hidden in the blue fur as he pumped his dick, panting like a ravenous dog. Koi quickly dipped a finger into his mouth, swirling it around in his spit before pulling it out and sticking it between his sibling's cheeks, getting a hard grunt from Tuna as he wriggled it inside of the tight hole, 
“Just try to relax and don't clench too hard.”
Getting the finger all the way down to the base, twisting it around as the other boy's moans made his shaft twitch, the snug hole squeezing down as he stretched it out, Koi fingered his older brother for a few minutes before pulling out, eager to replace his digit with the real thing as he stared down at the wet, glistening, and twitching tailhole right in front of him. 

Burying his face into his hands, biting down on the corner of his blanket to at least slightly muffle his moans, Tuna felt his little brother entering him, feeling the hot and rock hard girth stretching out his tailhole as his own member jumped, spraying a rope of precum all up his belly and down the bedsheets. The sensation of his siblings filling up his ass, his rim stretching out over the throbbing cock as his pucker swallowed up the grunting pink dragon, was unlike anything Tuna had ever felt before. It was slightly uncomfortable at first, but he got acclimated with the odd feeling very fast, quickly learning to love it as the cub behind him gave the first proper thrust. Koi’s tip rubbed up against his prostate, buried deep within his tailhole, nearly knocking the wind out of his lungs as he gasped in pleasure, seeing stars in his eyes as he clawed at his bed, instinctively tossing his rear back against his brother's crotch, slamming the hatchling balls deep inside of him. Just as enthralled by the experience of his first time trying out anal, Koi grabbed handfuls of his older brother's fur, yanking himself forward and panting as he tossed his weight into every thrust, his tongue lolling out and his eyes rolling back, a look of pure heavenly pleasure on his face as he rocked his hips back and forth. The bed creaked as the two siblings humped, their combined moans only adding to the lewd orchestra that rang all around their room and out into the hallway, lucky that no other cub or any of the orphanage attendants happened to be walking by at that moment. Feeling the pressure building up inside of him once more, just as he'd felt when his brother had been lapping at his cock, Tuna hunkered down with an intensifying moan, every thrust pushing him closer and closer until he finally arrived at the orgasm that had been building the entire time. Koi felt the boy's tailhole clenching hard, locking him inside of Tuna as the blue dragon erupted into a mix between a whine and a roar, getting both brothers off at the same time. Completely hands free, Tuna blew his load onto his bed while his little sibling pumped an equally sized creampie into his asshole, both dragons grunting and trembling as they shared an intense and messy finish together, locked in an embrace. Panting harder than at the football pitch, Koi leaned against his brother's back until he felt his breath returning to him, looking down as he pulled out of the tight hole, slipping out and leaving Tuna leaking cum as he flopped over, both hatchlings tuckered out with splotches and ropes of cum staining their colourful furs. Rolling onto his back, feeling cum drooling from under his tail, Tuna looked down at the mess left behind, his cock still stiff, 
“I… I think we might need to go again…”
