Eon Incest [Commission]

, , , , , , , , , , , , , , , , , , , , , , , ,

What a better way to take care of a raging, legendary 'mon boner than fucking your own sister?

Geez, has it already been three weeks since my last upload?

So this was a commission for Mitch, who expressed me his frustration about there being far less than favorable amount of big-dick Latios content around. Naturally, I had to fix that.

To be completely honest, this was a bit of a grind to do, and I do hope it doesn't show too much within the final product. Looking back on it, I kinda wish I'd have done a better job but I had a lot going on both commission side and IRL so I'll probably just have to settle for what I wrote. I felt the prespective didn't work quite well as I would've liked it to and writing sex between characters who are essentially planes (...?) was a bit strange, but meh.

Think this is my first time doing brother/sister incest. Should do more.

Anyways, that's two more pokemon off the to-lewd list.

And as most of you have probably noticed, September is nearing its end which means it is soon COMMISSION TIME!!! I'll try to get the journal about it up within the span of next week, hopefully before friday. My apologies if I've kept you waiting.

Thank you for reading!


A heavy groan of frustration left your mouth as the hot throbbing sensation in your lower body sunk its claws deeper and deeper into your psyche, disturbing every single rational thought passing through your head. And you were supposed to be a psychic pokemon of all things. Every single inch of your floating body was filled to the brim with pervasive feelings of arousal, most of it naturally concentrated around your legendary male genitals that were suddenly so sensitive even a light breeze would send your monstrous shaft into a throbbing frenzy, your heavy Latios balls feeling like they were hanging lower and lower each passing second, hindering your aimless flight through the forest by weighing you down like two orbs of lead.

You still had no idea what exactly had gotten you this horny all of a sudden. One moment you were just floating through the forest, the next your sheath was spitting out the full length of your huge, pointy meat spear as if your genitals had decided to use 'Harden' completely on their own. Now you were stuck with a gigantic dragon-type erection, all three spine-decorated feet of it. Not to even mention the boulderlike knot that looked it would be too big for your sheath to contain even if you weren't erect. It was probably a more intimidating mating tool than you would find on your average Charizard or even a Mega Charizard for that matter. Truly a legendary dick.

Impressive as your malehood was, it was currently driving you insane with its relentless throbbing and the multiple hot surges yearning for satisfaction, for release. Your gargantuan pokecock was almost hurting to mate with anyone, anything, the frightening nubs of mating flesh adorning the big draconic glans of your member rising and falling with each energetic pulsation of your genitals, desperately clawing at the air in hopes of eventually meeting with the inside walls of a female pokemon. Your knot felt hotter than the fiery mane of a Typhlosion, swollen to a size big enough to satisfy a female Lugia if needed to, rocking a circumference over thrice that of the rest of your legendary breeder. It shared the bittersweet pain of pressurized lust with your fat Latios nuts that were constantly churning with reproductive desire, preparing to breed half the female pokemon in Sinnoh judging by how heavy they felt.

And you had no choice but to endure it. A task that kept getting harder and harder - much like your gargantuan breeding pole. It was difficult for you to even keep your balance properly whilst you floated forwards in the forest, the massive penile extrusion and its unequally distributed weight throwing your body off its natural equilibrium, causing your lower half to drag slightly closer to the ground compared to normal.

"I have to try and do something about this..." You muttered to yourself, seeking out a place to land with your red eyes as another profound throb traveled through your pokepussy-wrecker.

The constant, ruttish aching of your loins didn't make your search any easier, the draining effects of a raging hardon already starting to affect your vision with how strongly they gouged every, joint, muscle, and nerve inside your blue and white body. After floating around for much longer than you should have, you eventually had to settle for a modest patch of grass at the base of an old tree; a spot that was relatively secluded from any curious eyes.

Hastily making your way over, the tip of your big, hot dragon tool accidentally brushed against the lush undergrowth of the forest, the sharp jolt of pleasure from the brief contact momentarily rendering you unable to float and you crashed down onto the grass in grand fashion. There was a loud thump as your body met with the forest floor and you found yourself looking up at the barbed shaft and ovulation-guaranteeing glans of your own cock as it rose out of your crotch like the magnificent tower of virility it was. You watched as a huge glob of pre got squeezed out from the very tip of it, subsequently drooling down the side of your shaft, the tickling sensation of it sending the draconic breeder into a throbbing turmoil, every single muscle in your frame tensing up simultaneously.

"Fuckfuckfuck!"

You desperately fought back another drop of pre working its way up your urethra, unsure of how your body would react if you felt another sensation like that right after your first one. Exerting all the little control you had over your large genitals, you managed to stop the decent mass of pre-ejaculatory fluids from reaching your tip, the strange pressure it exerted on the walls of your urethra stopping somewhere inside the middle of your fat poke-member.

Trying your best to get your breath to settle, you gazed at the massive dragon-type dick as it throbbed vigorously on your crotch, reaching a good three feet out from your sheath, looking like it had gotten even bigger since you first laid your eyes on it. The same thing seemingly applied to your balls as well, the taut pair of legendary poke-nuts coming close to tickling the grass with how heavy they had gotten, visibly swollen with how chock-full of seed they were.

What on earth were you going to do to such a huge, insanely sensitive cock?

It had never actually crossed your mind, how exactly would you go about masturbating? The steaming shaft with its intimidating breeding decorations was too rigid to bend to the reach of your lackluster pair of paws and their poor range of motion, so your initial plan was immediately a no-go. The second best option you had would be to hump it against the grass, although, even as desperate as you were to relieve your urges, you weren't too keen on doing it since you thought of it as demeaning for a pokemon of your notoriety. Besides, you weren't sure it wouldn't even do the trick. What your cock really craved were the warm, fleshy insides of a female mon's pussy.

You were starting to sink deeper and deeper into desperation as your majestic mating meat refused to slow down its relentless throbbing, demanding some hot mating action posthaste. Your head became filled with thoughts about sex and mating, which only sent your arousal spiraling even further out of control than it already was.

Mating with a female pokemon would be the only thing able to satisfy your lust. But where and how would you find a female, especially one that could take your three feet of cunt-stretching fuckmeat, preferably down to the knot? You didn't know of any female mon inhabiting the forest besides your own sister, Latias, who, even if you were to somehow be able to convince to help you, wasn't anywhere to be seen and you sure as hell wouldn't be able to go about looking for her while you were like this. The situation was hopeless.

Aroused out of your mind, you couldn't help yourself from thinking about your sister some more, now that you had already gotten her image into your head. Your fight to keep any lewd thoughts out was short-lived and you ended up imagining yourself breeding her before you knew it, being too horny to even feel any guilt about it. You simply wanted to fuck, and fuck bad. She was a legendary too, after all. She should be able to take your cock, no? Fuck, you wanted to see her.

Going borderline insane with lust whilst thinking about your own sister, you didn't even notice one of your abilities, [Sight sharing] being activated; the ability which would allow your sister to see exactly what you were seeing. And what you were seeing was your fat, throbbing dragon cock.

...

Latias was floating a good half a mile away from her sexually struggling brother, the younger of the two legendary siblings spending time on a calm and breezy riverbed just as she usually would. The day had been mostly uneventful for her so far and she was feeling slightly bored by the monotony of it all. Not to mention she was also feeling a bit frisky as the mating season was fast approaching. It was a real shame there weren't any other legendary pokemon in the entire region, well, except for her brother of course. Other, smaller mon were mostly intimidated by her presence, so mating with them was immediately out of the question.

"Haaahh~ If only there was a handsome, big legendary pokemon with a real fat, juicy cock to help me through the mating season this time around." The red and white female mon sighed to herself, staring into the happily purling stream beneath her. "The best I could probably do would be a Charizard... But most of them aren't that impressive down there either... Geez, why do we have to reside in this specific region? I want some legendary dick to pound me!" The floating pokemon fidgeted about, airing her inner frustrations to nobody.

Continuing to float around in a downcast, pouty mood, the female Eon pokemon suddenly sensed her [Sight Sharing] being activated.

"How odd... Brother doesn't usually show me anything, what could it..."

Latias stopped mid-air as her eyes opened wider than that of an Unown's as she found herself staring at the biggest, thickest cock she had ever seen, through her own brother's eyes. She could immediately feel the heat permeating through her lower body, her female brain reacting instantly to the sight of such a proficient-looking breeder. Everything about it was perfect, the barbed glans built to scratch any itch a female mon could have, the multiple rows of the same, pussy-raking spikes decorating the absurd length of the extremely long mating tool, the knot of which nearly rivaled her own head in size. Everything.

"W-w-wha- W-w-who?" The flabbergasted Latias stuttered, it taking her some time to recognize the familiar blue and white body to which the thick obelisk of pokemon sex was attached.

"Hel~lo brother!" She whistled, voraciously absorbing the view of her sibling's massive poke dong through the unique ability she and Latios shared. "Gosh, where has he been hiding that thing... It looks big enough to breed the Arceus herself... Wouldn't mind getting my pussy smashed with that!"

The flustered female could feel her lower half starting to heat up even more.

"Aww... It looks like it's in pain..." She couldn't help but giggle a bit as she watched the desperate twitching of the enormous shaft. "Hmmm... I guess he has no females to mate with either... Such a shame to have a cock so hot and huge unattended... I bet he's just dying to breed the first female to come his way..."

She thought about her own words for two, long seconds before dashing off into the forest, flying nearly as fast as a Ninjask with the image of her brother's cock embedded into her yellow eyes.

"Don't worry brother!... Your lovely sister will surely help you!"

...

You were slowly going more and more out of breath as maintaining such a huge erection took an inevitable physical toll even on your relatively strong body. The pre-cum was now leaking out as a steady stream, most of your lap and scrotum already wetted comprehensively with how much of it was gushing out with every throb. Your whole carcass felt sluggish and heavy, taking a constant beating from your libido which out-classed every other sense and desire in your system by a landslide. You didn't know how much more you could take feeling like this.

Your earlier musing about humping the grass didn't seem like such a bad option now, any kind of outlet for the burning ball of lust growing immensely more enticing by the second. Humiliating as it would be you knew you had to do something. Screw it if some lowly Rattata saw you humping the ground. There was no way you could take it anymore.

"Something wrong, brother?"

You heard a familiar, slightly cheeky voice from the shadow of a nearby tree, spotting a pair of floating yellow eyes gazing at you and your three-foot-long, pulsing predicament. At first, you weren't sure if all of it was just a horny hallucination of your male mind, but as the female mon floated closer, you were able to recognize her as your sister, Latias.

"Geez~ I had no idea you were so well-hung dear brother! You're big enough to breed a Groudon!" The jovial female mon giggled, her eyes glimmering with intrigue as she drilled holes into your cock with her gaze.

"S-sister I..."

"You wouldn't happen to be in the mood to mate?" The sarcasm in Latias' happy voice was slashing. "Your cock looks like it's dying to fill somebody up... Too bad there aren't any females here big enough to take it..."

Why did your sister suddenly smell so enticing? She wasn't supposed to be in heat for the next two weeks at least, and yet you caught the scent of her pussy from a good twenty feet away. And had she always been this beautiful? Erotic? Sexy? Her mere presence was enough to make your urges go wild and the fantasies about the incestuous mating came rushing back into your mind.

"Well... I guess there's me..." Latias smiled mischievously. Your heart skipped a beat. "I should be able to tame that cock... We are practically the same species after all..."

You were unable to make a single sound as much as breathe as you witnessed your smirking sibling carefully landing on the grass some ten feet away from you, deftly hiking up her crimson rear to expose her profusely leaking legendary sex for your eyes. A rope of pre got launched nearly three feet up from your tip in the perfect representation of your inner reaction to the sight.

"How about it brother? Care to have some fun with your breedable little sister?"

"Holy Arceus! That thing is even bigger in the flesh... Fuck I want my brother to breed me already... Come on! I know you can't resist my pussy when you're already that hard!" Latias could feel the lips of her fat pussy starting to swell, her body excited beyond reason at the prospect of finally getting to tussle with a cock matching her cravings. She couldn't help but wantonly wiggle her rear end at the hung male whose intense stare she could feel on her leaking sex.

You couldn't take your eyes off your sister's pussy. Her female entrance was magnificent, the pair of full vaginal lips glistening wet with her she-mon nectar, already slightly spread apart as if inviting you in to ravage the pink opening in their betwixt by allowing you to look directly inside her. Being a pokemon of similar build, she absolutely matched you with the size of her genitals, the vertical diameter of her pokepussy easily exceeding seven inches, the horizontal width of her hole simply waiting to be tested by a big, meaty cock. Her steaming sex crevice looked like the perfect fit for your massive boner; a fact which didn't lessen your erection agony one bit. A pussy that big straight out begged to be filled by the biggest Latios cock around, that cock being your - her brother's - cock.

As much as you wanted to fight the thoughts about subjecting your own sister to the rough, messy mating your body craved, you instinctively began to levitate, floating your body off the ground, and aiming your big, hot hard-on towards its oozing, winking target. A set of pleasure-inducing shivers roamed your body as you slowly floated closer to the female mon who so sluttily presented herself for breeding. The grass in your wake was left glistening with a river of pre-cum.

"Come on bro! I know you want to!" The Latias giggled, sticking her rear even higher up into the air so you could see the ropes of her sticky sex fluids dangling from her entrance even better.

Her words, as innocent and lustful as they were, sparked some feelings of hesitation in your mind, despite the vocal demands to breed from your lower half. Could you really do this to your own sister...?

"Fuck... What is he waiting for? Just mate me already! Can't he see how wet I already am for his huuuuge dick?" The female mon sighed with frustration in her mind, her pussy winking all the more desperately the more she was able to devour the sight of the huge Latios dick throbbing only a few feet away from her anticipating, breedable cunt. "He's not seriously getting cold feet now, is he? I'm right here! Just breed me!"

Even with every individual instinct in your body protesting your decision to open your mouth, you managed to eventually stutter: "I-I don't know if w-we should..."

"Your honestly still saying that dear brother?"

You were slightly surprised by the uncharacteristically snappy response from the usually so gleeful Latias.

"Then what are you going to do about that? It's not like you're going to find another legendary pokemon to breed!"

She did have a point. Still, as much as it pained your inner male, your tungsten-thick erection, and your aching balls, you attempted to refuse her. "...I'll manage... Somehow..." You said, trying your hardest to tear your eyes away from your sister's delectable cocksleeve-opening without much success.

"Fine! We'll have it his way then!" The sex-starved Latias thought, activating her psychic powers with her brother's humongous dick as the target. "No way I'm going to miss a chance to get dicked-down by that thing!"

You nearly lost control of your levitational abilities as a wave of debilitating pleasure abruptly prompted you to moan out loud, your hot poke-breeder jumping up and down, flinging thick Latios pre all over the place. It took you all you had not to crash down onto the grass for the second time as your body was suddenly getting assaulted by sensations of sexual satisfaction, your draconic erection going completely crazy as it was simulated by... something. It felt like your cock was being stroked, for the full length and diameter of it too. The dozens of fleshy prickles decorating your malehood fluttered like leaves in a breeze as the odd sensation ravaged your cock, leaving you trembling and gasping for air from how incredible it felt.

"That's not good brother... Your sister is offering herself up for you so nicely and you refuse her...? You know that's not going to fly, do you?"

There was no way you would have been able to respond to her, your entire body paralyzed by the violently exploding sparks of pleasure spreading from your shaft, violating every plane of your body however they liked. You were now leaking pre by the bucketful, each psychic stroke made by your beloved sister pumping out a real thick rope of the sticky translucent stuff, your legendary nuts feeling like they were swelling up yet again from the intense stimulation. How you had not instantly busted a nut from being jerked off like this was way beyond your comprehension, the hot load of pokejaculate cooking up in your gonads still actively seeking a way out of their spherical prisons, concentrating its pressure onto your enormous knot.

"How do you like that, brother? Bet you'll be thinking twice about not breeding me now aren't you?" The lusty female mon thought, momentarily getting lost in the copious splashing of the familial pre-ejaculatory fluids that the target of her desires was squirting out so enthusiastically. "...Take this!"

Just as you were sure you were going to climax, the odd sensation on your cock abruptly faded, blue-balling you in the worst possible way a rutting male could experience. A defeated and sorrowful whimper escaped your mouth as the pleasure wasn't quite enough to bring you over your edge and the churning in your balls got even wilder as a result. Your entire shaft, knot included, protested the lack of stimulation, the ovulation-inducing barbs on your majestic meatsicle erecting themselves to their full size as the increased pressure throbbed inside your legendary breeding tool.

You cast a look into your sister's horny eyes and knew it had been intentional. Although, it didn't really matter whether it was since there was no way for you to retaliate in any scenario. You were at her complete mercy.

"Still nothing, huh? I thought he would have lost it and fucked me by now..." The Latias pondered, feeling slightly frustrated whilst simultaneously greatly enjoying the reaction of his brother's genitals. Being able to feel out her ideal cock with her mind was as fun as it was arousing.

You moaned again as the stimulation returned to your cock, this time focusing more on your glans and knot whilst only teasing the middle of your gargantuan crotch monster. The pleasure in your loins began building up again, racing towards its not-too-distant tipping point at nearly twice the speed of before you had been denied completion. The desire to cum was so strong inside your lower half that it made you want to squirm, a pair of desperate whimpers crawling their way up your throat while your excited partner watched you with her eyes gleaming.

It was coming, you could feel it. Just a bit more and you would lose it for sure.

Alas, the burning claws of disappointment were the only thing to scratch your shaft as your cunning sibling left you balancing on the edge of pleasure for the second time, the gigantic Latios shaft with its many barbs and mammoth of a knot jumping up and down uncontrollably with the need the blast its surroundings with nasty pokemon jizz. Being denied again felt so excruciating and so blissful at the same time that your mind nearly went blank, the lust churning inside your fat Latios balls and roaring inside your diamond-hard shaft, screaming, demanding for a release. You felt like a gentle breeze could set you off into an orgasm the likes of which the entirety of Sinnoh had never seen before.

"Brother is so cute when he's getting edged..." Latias had almost forgotten the true goal of her psychic stimulation, getting absorbed in taking in the overwhelming desperation exuding from her brother and his about-to-explode pokecock. "Just a little bit more and he can't help but fuck me nice... and deep..."

Having already been denied twice by your cunning sibling, the third round of mindly cock-stroking hijinks a-la-Latias was the one to take it too far. Your shaft became electrified in a split second as soon as the first strokes passed through your monstrous fuckmeat, the dam holding back your climax somewhere deep inside your mighty knot finally breaking, a messy cascade of pokemon cum breaking out from behind it in a huge flood.

You had no control over your facial features nor the sounds you were making as the focused hyper beam of ejaculate abruptly rushed through the length of your malehood, erupting out from the tip of your draconic female-mon impregnator like a hot geyser of poke jizz. Your sister's jaw dropped as soon as she realized the absolute volume of liquid eggs being blasted out by your monster mating rod, the surge of the sticky liquid flying almost straight over her head in one, continuous rope, reaching nearly thirty feet away from the tip of your twitching poke-breeder, even then being stopped only by the robust trunk of a tree in its path.

"By the Arceus! Was he really this pent up!?" Latias gasped in her mind, running her eyes along the whole length of the majestic stream of hot Latios cum arcing over her body and battering the bark of the poor tree blocking its path a good thirty feet away from her. "Fuck! To think I could have gotten that inside my pussy! What a waste..."

The horizontal waterfall of cum continued to stream out of your cock for the better part of thirty seconds, the hot lust burning up your legendary frame getting drained out of your meaty sex scepter one pleasurable pulsation at a time. One was almost able to hear how the hot seed rushed up from your balls and into your shaft, the wet, lewd sounds it made as it left your shaft echoing in the trees surrounding you and your sister as you came a small river of pokemon seed in a single go from your hgue malehood. All of it felt so mind-blowingly good you had a hard time keeping yourself levitating, especially as the pressure of your explosive ejaculation wanted to propel your lower body back with considerable force.

Your vision was still flickering as the messy stream of steaming hot egg batter weakened into individual spurts, multiple of the ropes you shot now landing on top of your sister's red and white body with her gasping in delight as she received the residue of your orgasm on herself. You felt like you were running out of oxygen as your nasty fuckstick jumped a few more times in its last attempts for glory, squirting out a pair of pressurized cumropes from your urethra before seemingly calming down, the next dozen streaks only reaching a few measly feet in front of you.

Your body, which had felt like it had been on fire for the last three minutes, cooled down considerably as if it had been suddenly submerged in water. The agony of not being able to cum dissipated from your system as the flow of semen from your legendary fucker dwindled down to a weak drool, drowning the blades of grass beneath your belly with its sticky coat. Your vision and psyche were gradually returning to you, the pressure inside your loins relieved, your body tingling with bliss after a good, extremely overdue nut.

"Wow! I had no idea a male would be able to cum this much..." The partially glazed she-mon shivered with desire, having received a healthy appetizer of her brother's ejaculatory capabilities directly onto her back. She could feel her cunt heating up as the desire to be bred skyrocketed within her loins. "Brother looks so satisfied now..."

It took a short while for the horrifying realization to hit the rutting Latias. "No! Wait! I can't leave him too satisfied... He will have no reason to smash my pussy if he's already content!" She began to panic. "W-what should I do? I'll die from this damn heat if I'm not bred, and bred quickly! I need to get him to fuck me... But how...?"

Her horny mind working overtime, the lusty legendary was eventually able to come up with a plan that would guarantee her getting her cunt filled with the appropriate amount of dick. It wasn't a pretty plan or an especially kind plan for her brother, but she only cared about getting herself mated and went forward with it anyway.

The muscles in your body were starting to relax one by one, allowing you to breathe a sigh of relief as the pleasure no longer assaulted your body with such consistency. Your meaty pokecock was slowly starting to deflate, even as your eyes were drawn towards the enticing lips of your sister's fat pokepussy, the glimmering, wet crevice winking at you with palpable hunger. The feeling of tension finally leaving your shaft felt incredible after the long, long time of your body having to maintain such a towering erection.

A loud yip of surprise tore your lips apart as your cock suddenly jumped back to its full, breeding-ready size, the same feelings of intense lust and agony returning to your hefty gonads and trembling loins in the blink of an eye. In no time at all, you were gasping for breath and moaning in frustration, the feelings of relief from your big, messy climax gone in a heartbeat, leaving your genitals heavy with reproductive desire, just as they had been before your orgasm. Translucent pre began gushing out of your urethra in the same volume as before, the sight of your sister's dripping pussy drawing your eyes to it like a magnet.

Why did it suddenly feel like you hadn't cum at all?

Past all your trembling and squirming, you were able to see the devious smile on Latias' face. This was her doing. She must have used some of her psychic-type abilities to make your body forget the orgasm.

"W-What... D-did you do?"

Simply talking took you a tremendous amount of effort.

"So now do you wanna breed me?" Was your sister's reply. She raised her rear even higher and wiggled it about to entice you into fucking her. And it was working.

Your body had already begun to float towards the presenting female, not only the sight but the scent of her exposed sex pulling you in like a Magnemite, all three feet of your malehood more than eager to explore the feminine depths of the compatible set of genitals. Your desire the fuck was overflowing.

"That's it, brother... Float on over and fucking pound your little sister with that huge cock of yours..."

Before you even realized it, you were already close enough to feel the heat from the hungry Latias crevice against your tip, a thick layer of humid air being the only thing separating your glans from the moist embrace of a female pokemon's pussy. You were still hesitating but couldn't overcome the sweet temptation of your surprisingly slutty sibling, your male instincts guiding your lower half closer and closer to the pink groove of sexual satisfaction that was waiting to milk you dry with its welcoming walls and swollen lips.

"Matingmatingmatingmatingmatingmatingmatingmating..." Was the mantra echoing inside your head as you pushed the throbbing helmet of your dragon-type fuckmast in between the drenched gates of your sister's sex, the sensation of pure euphoria and ecstasy which flooded your body as a result prompting you to slam your entire length inside with a single jab of your blue hips.

The dual-type female craned up her neck and opened her mouth, the moan she made not reaching your ears as the roaring of your male blood covered up all the noises from your surroundings for a short while. You were able to feel each individual spine on your fat dragon dick digging into the soft flesh of your sister's cunt, the hot, wet kiss her lower lips smooched your massive knot with, and how the walls of her quivering sex tunnel echoed the powerful throbs of your cock as you and her were finally connected.

You didn't register moving your body but were able to feel the firm resistance of smooth vaginal walls on your cock as the ovulation-inducing decorations your meat was adorned with raked against the slippery insides contracting around your girth. Something wet splashed against your knot as your body nudged back and forth on its own, the hot lips surrounding your shaft attempting to swallow the thickest part of your malehood but to no avail. You were moving your hips and didn't even know it.

At least not until the volcanic eruption of hot, scalding pleasure permeated up from your loins, causing your mind to blank out momentarily with how rapturous of a sensation it all was. The slashing, pleasured scream of the mated female reached your ears as soon as you came back to, a similar vocalization leaving your maw with an equal amount of desire and emotion behind it when your mind eventually caught up with what your body was doing.

You were having sex. Hot, wet, pounding, noisy, incestuous, cunt-stretching, ball-gouging, breeding-intended, egg-conceiving sex, the pleasures of which were now having a field day battering you and your sister's body into the deepest pits of carnal bliss a male and female pokemon could experience together. The whole surrounding forest was echoing with the sounds of your incestuous debauchery, the lewd, wet noises made by a Latias' legendary pussy as it got pounded by its Latios counterpart, the soggy slap produced by your knot smashing against the soaked entrance, accompanied by the louder slap of your full, rumbling testicles meeting with the rump of a female.

"W-we're doing it! We're really doing it!" Latias was steadily drowning in her own ecstasy as she had finally found a cock to scratch all of her many inside itches properly. Latios' cock wasthe perfect fit for her hungry sex hole, nicely filling up the whole depth of her quivering female tunnel and providing ample stimulation to both her insides and entrance with the many nasty spines of the draconic fuckstick. She could already feel herself starting to ovulate with how deeply she was being fucked, her voracious cunt still screaming for more, putting in the work to milk the precious legendary eggs out of her brother. "Mmhhh~ Brother is so rough!" She thought as her mind was steadily melting.

The incredible compatibility between you and your sister's genitals was becoming more and more apparent as you continued to pound her slippery sex crevice with all you had, the tight, loving caress of her inner walls enticing you to mate her harder and faster as your knot voiced its frustration by swelling up to a size that could put any competing pokecock to complete and absolute shame. The desire for another ejaculation thumped within your knot acting as a crude reminder that the most impressive part of your mating meat was left grossly unstimulated, whilst your shaft and glans got to wrestle with the succulent tunnel of incestuous pleasure all they wanted. Foreign as it was, you could recognize such an urge instantly.

It had been less than a minute and you already wanted to knot your female so badly, your instincts driving you to move your hips faster and faster with the intent of really stuffing your sister full of the legendary cock she so obviously craved. An extremely generous amount of Laitas fluids was splashing all over the place as your knot made violent contact with your female sibling's lower lips, her moans of pleasure intensifying in accordance with your thrusts.

But even despite your best, most desperate efforts, there seemed to be no progress. The passionately contracting Latias cunt didn't seem to be getting any looser, and on the contrary clamped down on your shaft even tighter, making any attempts to knot such a greedy orifice borderline impossible.

"Aww~ He's so cute when he's trying so hard to knot me..." The younger Eon pokemon was eagerly observing the fiercely groaning male over her shoulder. The expression on her brother's face was so deliciously frenzied that she couldn't help but tighten herself up even more, really about to make him work for it.

"Something wrong big bro?"

You flinched to the crafty giggle echoing from below you.

"Can't fit that fat knot of yours inside? Of course, you wouldn't... It's not like I'd let you do it so easily..."

Her words echoed in your ears as you were helpless to stop moving your hips, another orgasm steadily rising up from your heavy scrotum and tickling the throbbing base of your shaft from the inside. It didn't help that she decided to squeeze her pussy on your cock with nearly twice the moxie she had previously.

"...You're going to need to spread me open some more if you want it to fit..."

Spread her open... But how? Your hands were already busy holding onto her trembling wings and lacked the range to do anything significant from your position anyway. Your cock was doing the best it could with the amount of blood your body possibly could pump into it without causing a loss of consciousness.

The swirling flood of potent Latios sperm was already pounding against the back of your knot, seeking entry into the upper parts of your dilating urethra as you finally realized what you needed to do. The lewd epiphany came to you almost naturally once your lust was reaching unbearable levels of intensity, your body acting on it on an instinctual impulse before your brain could even properly process it.

Much like your sister had psychically stimulated your member, you were now targeting her orifice with your ability, spreading the puffy Latias lips apart with the rattled psyche of a rutting male pokemon while your devious partner released a cry of raw lust and eroticism from her maw. You could tell she was fighting back at you with her body, but nothing could stand in the way of your psychic power as a twice-overdue orgasm scorched your loins.

You hammered your knot against her stretching female entrance, slowly feeling more and more of the thick insemination-insuring bulb of taut, veiny flesh starting to sink inside the slutty crevice you were forcing it inside. Both your bodies were tensed up to the maximum as you leaned even more weight onto your hips, eliciting a whole bunch of screams from the female being knotted as the dreaded halfway point of your penile base sought purchase to the quivering insides of the moaning female. It was a mystery to neither of you what would happen once the deal was sealed, your shaft already going wild with its throbbing just like it had before your previous ejaculation.

"H-he's really doing it! He's going to knot me and seal my pussy up for good!"

"C-come on! K-knot your s-sister!"

The lust-oozing female voice echoing in your ears, you ground your groin against the beautifully crimson backside of your Eon sibling with all you had.

*POP!*

It felt like getting struck by a dozen thunderbolt attacks at once, your vision going white, multiple simultaneous spasms taking control of your body for a brief moment of pure, highly concentrated bliss. The fat bulb decorating the base of your legendary pokecock lurched forwards and was promptly sucked into the humid grasp of the gushing Latias cunt, the full three-foot length of your member now enveloped in the soft, cockmilking sensation of a female mon's genitals. The dozens of spines on your nasty male organ erected themselves up to where they were nearly vertical with your shaft, sinking deep into the welcoming walls of flesh as the entire pole of poke-meat inflated in size, securely locking itself inside the profusely moaning female to make the following ejaculation count for all it was worth.

Your maw got locked in a soundless gasp as the absolute deluge of legendary-grade ejaculate pushed itself up your urethra faster than a charging Rapidash, exiting your member with the pressure of five concentrated hydro pumps, slamming into the very back of the writhing Latias pussy with almost explosive force. The massive flood of reproductive liquids carried palpable recoil for your floating body, both you and your squirming sibling getting dragged nearly a whole foot backwards on the grass with how violent of an ejaculation accompanied your second orgasm. Had your cock not been so securely stuffed within the rapidly contracting female orifice there was a good chance the strong current might have popped your dick right out of her.

The pleasure of finally being able to relieve your lust with a physically compatible female was insane. Your first climax couldn't even compare to how much bliss and feelings of pure ecstasy your second nut conjured up inside every single corner of your floating frame. The agony and despair you had felt from not being able to sate your raging hard-on was being swept away from your mind with each powerful throb of your Latias-stretching tool, the following rush of positive brain chemicals being near intoxicating with how strong it was.

You could literally not stop cumming inside your own sister's pussy. Both of you were completely powerless in stopping the whimpering, panting, or moaning induced by the shared, continuous barrage of bodily pleasure your genitals were keen on providing each other with. Your slutty sibling was drooling against the ground with her face stuck in a lewd, satisfied grin as you filled her up one hefty rope of Latios cum at a time, even her surprisingly roomy insides reaching full capacity in less than fifteen seconds of you blasting out the contents of your balls, balls which seemed to have an endless supply of the thick white stuff to serve.

Eventually the liquid pressure inside the panting mess of red and white grew too strong and streaks of jizz began escaping the lock of your knot. Your second orgasm was soon starting to rival your first one with the potent, sticky mess it made on both your sister and your shared surroundings. And yet, you still could not stop cumming.

A minute passed. Maybe even two, and you were still seeding your sister at full throttle.

Being held hostage by the continuous sensation of orgasm eventually kicked your reproductive instincts into total overdrive, driving your already peaking male desires sky-high within a split second. You faintly registered the Latias' pleasured gasp from somewhere on the grass as your male urges did what they wanted with your powers, abruptly shapeshifting your dick into a bigger, badder, and more powerful mating tool than it already was, multiple new barbs sprouting from the rigid surface of your shaft, the biggest ones up to three inches in length to really extract the pleasure from the insides of your legendary lover. The entire thing grew vastly in both length and diameter, the spasming cunt around it getting stretched to its absolute limits with how much male meat was suddenly packed into its grasp.

"Nngghh~ H-He can't... E-even bigger?" The Latias' lower half felt like it was being split in half by the aggressively inflating beam of male mon fuckmeat, her screaming cunt only barely accommodating such a huge amount of cock despite not being amongst the smallest of female crevices in Sinnoh by a longshot. The newly-grown spines on her brother's dick were like small knives of infinite pleasure, digging into the sides of her tunnel and dragging the moist flesh around however they felt like, each thrust from the orgasming Latios worth a small climax of its own. And on top of that, the blue and white male was still cumming like a broken fire hydrant.

The Latias felt like she was about to pass out from having so much cock in her. She reckoned this must have been her comeuppance from her frivolous wish from before.

You could feel the veins lining the inside of your absolute monster of a pokemon cock popping to the surface of both your knot and shaft, further adding to the grotesqueness and pussy-pleasing ability of your male tool by spicing things up with randomized bumps and ridges all around your malehood. Neither you nor your sister doubted for a single second that you now had the biggest, nastiest cock of all male pokemon in the entire world. Such a majestic manifestation of male virility begged and demanded to be worshipped by females. The enraged male organ craved to do what it was made to do and made sure it got some much-deserved action by immediately infecting your mind with the overwhelming desire to mate even as you were mid-orgasm.

Unable to fight back against your enhanced pussywrecker, you began to move your hips, forcibly tugging your engorged knot out from the creamed depths of your fellow Eon pokemon who screamed from pleasure as the swollen mass of cock got squeezed outside her hole. A whole wave of Latios cum got splashed into the air as you aggressively hammered your knot back inside the gaping entrance of the female legendary's lower mouth, filling the convulsing tunnel back to capacity with your seed as your orgasm was still far from done.

You pulled out again, another wave of white pokejaculate splashing onto the grass as the liquid Latios lust was able to escape the confines of its barely lucid flesh container. Some of it nearly jumped up to the leaves of a nearby tree as you forced your knot back inside, quickly working yourself up to a pace of good old knot-fucking of your own flesh and blood.

The entire forest clearing was soon completely covered in hot, sticky Latios seed, loads of it splashing out with each rapid pump of your blue hips, the gargantuan pair of gonads decorating your crotch churning up more and more for your shaft to jet out as your orgasm continued for the third consecutive minute. You continued to thrust into the spasming she-tunnel with complete abandon, each new stab delivered inside your living cocksleeve nearly blinding you with pleasure, prolonging your orgasm by stimulating the flow of semen within your genitals onto even greater heights.

The sounds of your extreme knot-pounding matched the act itself perfectly, the wet splorching of steaming Latios seed bursting out of a brimming Latias cunt as it got squeezed out by the intruding bulb of veiny flesh echoing all around the forest, letting half of the region know what was going on between the Eon siblings. But perhaps even better at conveying the impact of the intense incestuous mating were the erotic, hair-raising screams released by your panting partner, each knotting eliciting a different, pleasured screech from her gaping maw as she vocally celebrated being bred the way she had always wanted. By the biggest legendary dick around. Her beloved brother's dick.

You didn't know how long you went on with it all. One, two, three, or more minutes? All you knew was that was the end of the intense pussy-raking, cervix tickling, orgasm-inducing knot-fucking you were both spasming like a pair of electrocuted Vaporeon, the sheer physical strain of the rapid, cum-spewing pussypounding eventually catching up with you.

No longer able to keep thrusting, or even hold yourself afloat in the air, you knotted the whimpering Latias for the final time, spending every last remaining drop of your legendary seed inside her cunt as you collapsed on top of her. You could feel her climax for the umpteenth time during your long session of mating between family, her soaked insides giving you one last loving caress with their thoroughly abused folds before relaxing their grip from the sides of your shaft.

The forest grew silent, the total absence of sound broken only by the light patter of your jizz dripping down from your taut scrotum into the massive pool of the same substance coating the forest floor beneath your lower half.

Given the awkward position you were perched in on top of the strange shape of a Latias' backside, you eventually slipped down from on top of your nearly passed-out partner, getting your full-sized knot and a good part of your shaft dislodged from inside her in a single go as your body loudly thumped against the jizz-coated grass below. The abrupt movement made the female pokemon moan, her voice almost wistful as it left her lips, yet another flood of cum gushing out from inside her gaping groove.

The stinging odor of semen tickled Latias' nose as she laid still on the cum-covered forest floor, both the inside and outside of her lower half thoroughly doused in the liquid offspring of her brother. Her female hormones were still running wild and even though she had been - almost literally - pummeled to the ground by pussy-splitting pleasure, she still had an ounce of unsated lewdness within her system.

Even though she had had the privilege of feeling the ins and outs of the colossal pokecock with her pussy, she still desired to see it in the flesh; the elephantine pokemon phallus that had brought her so much pleasure. Only barely able to move her hips, the exhausted female mon jerked up her lower half, nearly losing herself to the divine sensation of the big spines raking the sides of her pussy as she lifted her hips off from the imposing impregnation tool with a weak groan.

The delighted gasp of the familiar female voice snapped you out of the post-nut haze which clouded your thoughts, prompting you to lazily crane up your long neck to the best of your ability.

You saw the lewdly grinning face of your sister facing you from the opposite direction, her yellow eyes licking the shape of your malehood as it rose up from your crotch like a mighty Steelix. This was actually the first time you were able to take a look at your own cock and the intimidating monster of a phallus you had unwillingly shapeshifted it into.

And what a sight it was.

Length-wise the entire thing reached almost four feet up from your sheath, having grown a good half a foot during the transformation. The circumference of the shaft was close to twenty-four inches, the knot's nearly thrice that, the sheer volume of your meat being pretty breathtaking in and of itself. The shaft was still fully hard and rigid, an array of spines covering almost its entire surface, the biggest and nastiest ones decorating the fringes of the draconic glans close to the tip. Many of the thick veins keeping up the blood circulation in your member were still very much bulging out from under the surface, coursing all over your knot and shaft like small, throbbing rivers on a map.

The entire thing was glazed in cum, throbbing at a decreasing pace under the sticky coating of potent poke-seed, adding further impact to the visual of it sticking out from your crotch. It was certainly a legendary breeder, perhaps even tiptoeing on the verge of deserving the title of a mythical cock with how incredible it appeared.

A soft giggle from your sister broke off your self-admiring of your member and you looked past your swollen genitals at the smiling face of your fellow legendary.

"I can't wait for the mating season to start..."

Your cock throbbed in agreement with her words.
