I had a moment where someone had to tell me the smt5 protag was a boy and this had to exist because of that

Premise:Shujinko, the SMT5 protagonist, has run into awful luck again! The spell Mudo’s connected and instantly defeated his fat cheeks. Can he make a strategic retreat or will his urges to snort gigantic demon testicles get too much in the way?

Note: My only SMT-adjacent knowledge is from Persona Q. There’s so little info on this character at the time of writing (Jun 2021), their name is just the romanji for hero. Sorry if there are a few bumps that bug long time SMT fans! I’m just a sucker for blue haired protag boys and needed to see him getting plapped ASAP.

The demon horse beast attacked. Shujinko braced for impact. Mudo!

Shujinko froze solid. His legs and arms stayed as still as rocks as his whole body crashed into the sand! Goddamnit, he got hit by an instant kill spell again! This wasn’t fair! How did this bastard horse enemy thing Gamigin always land this crap when he couldn’t hit anything!?

Thankfully, even though the spell was supposed to cause instant death, Shujinko was blessed with at least some semblance of resistance to it. Instead of just flat out stopping his heart, it just put him in a very vulnerable state where simply the only option was retreat. If he didn’t move soon, some of these demons would surely get the wrong idea again…

Really though, could those wild dream-like entities be blamed? Here they are ambling around in some horrible desert facsimile of Tokyo, a world filled with nothing but scorn and suffering, and then Shujinko shows up. This long haired, pretty faced, androgynous looking and sounding twink wrapped in a skin tight suit was just wondering around fighting demons. His eyes could bend a man’s sexuality effortlessly, let alone those big girly hips and his wobbling cheeks! What soul cursed to wander this horrid land wouldn’t get all excited when eyelashes that stylish or hair that easy to use as handlebars was around?

N-not like Shujinko liked it! He had a girlfriend back in real Tokyo! Or, well, a crush. Getting groped and more by the monsters here whenever he was defeated was just an agonizing part of defeat. He absolutely didn’t goad monsters content to spare him into spanking his big round femboy ass for the road. Nor were his fantasies growing questionably full of being taken by monsters again. Really, he only masturbated to losing his virginity to being buttfucked by monsters SOME of the time! He still fapped to girls!

Yet again, that storm of questioning his own sexual identity raged in Shujinko’s head as he lay there on the sand. He’d long since recovered his use of his arms and legs. He was perfectly capable of fleeing! Yet, he stayed there, extremities glowing against the sand. If he was so straight, why didn’t he get up and leave? Why did he want that big, horse-like demon to get closer and closer? Shujinko dismissed it all as just a one time experiment. Instead of fleeing, he shifted positions.

“I’m defeated, demon.” Shujinko lamented.

The cyber femboy adjusted his position, shifting from his modest pose resting on his back, to face against the sand, ass raised high into the air, presented to Gamigin.

“Please, I know this world must have stoked such strong desires in you upon seeing my untainted flesh.” Shujinko continued. “Claim me as your mate and spare my life so that I might fight another day…”

The horse-like beast snorted. Then, a deep roaring chuckle rang out of it.

It spoke like a thundering god. “You speak of your flesh being untainted, yet of all possible escape options, you lean into one so thoroughly… emasculating.”

Shujinko’s eyes darted to the side. His cheeks grew red.

“I need none of the pleasures of earthly life. I shall spare your life and allow you to continue your journey.” Announced the beast.

Shujinko’s brow sank. He stood up, as if he totally wasn’t in a helpless state where a raging animalistic demon could take him.

His inner high school aged rudeness started to bubble through. “Hey! What gives! You demons are supposed to like… you know…”

Shujinko’s words faltered as he realized just what the hell he was saying. The horse-like god was amused.

“As I see the situation, it seems as though I, the demonic beast, am not the one with the darkest desires in their heart. Tell me young human female…”

Shujinko couldn’t help but correct that. “I’m a boy…”

Another deep laugh rang out of the ethereal being. “My, the world of humans has progressed so far since my days amongst Solomon. To think the earth can now bear men as soft and delicate as the fairest women…”

How mortifying. Shujinko’s head tilted downwards in shame, frazzled cheeks still flustered full of embarrassment. Worse yet, his skin tight suit gave a small flex at those deep, taunting words. Why was… why were insults making him aroused?

“As I was saying… “ Resumed Gamigin. “Tell me, young human male. I have no wish to humiliate you further and claim you sexually. Once our conversation ends, I shall leave you be. That said, I am… open to the idea of doing such perversities, provided you ask.”

Shujinko was ashamed. This horse thing had a perfect read on him! He was so choked back by those stinging words, he couldn’t manage a single sentence to a retort.

Gamigin awaited a reply. “Well then, I believe we are done here. Steel yourself for the cruelties of this world, for they shall-”

“Wait” Interrupted Shujinko. “I… Uh…”

Shujinko grew closer to the beast, trailing closer to its expansive rear.

Gamigin looked beyond amused. “Human male? Speak louder. What is it you desire?”

“M-may I…” Shujinko couldn’t sum up the words. He swallowed hard.

“May I… L-lick your…” He struggled.

The demon waited patiently for the pervert to unmask himself.

“M-may I please c-clean your balls and taint, s-sir…” Shujinko mumbled out.

“My my, I’m afraid I didn’t hear that. Would you please repeat it louder?” Gamigin teased.

“I… I um…” Shujinko couldn’t say something so brutally embarrassing twice. His mouth wasn’t good for words anymore. He could speak far louder and say so much more with his tongue. As his face grew closer and closer to the end of the horrid horse demon, Shujinko’s thoughts whirled with forbidden passion..

Shujinko was so close. Staring back at his sweltering gaze was the titanic ass of a horse demon, with features so tantalizing it bent and broke the little hero’s sexuality to pieces. An asshole the size of his skull. A taint just begging to have a face buried in it, to coat in that fresh sweat. And those balls… Those virile, egg-shaped orbs demanded all authority. Their look alone, standing at attention, constantly churning fresh gametes into that taut full horse ballsack, demanded some sort of caress. They needed a soul to hold them, a hand to grip them and feel their power, their raw masculinity… a level of manliness the femme little twink could hardly ever obtain.

So, if such fervent masculine power was out of his reach, why bother? Why not put those lips coated in neon blue lipsticks and claim such a powerful lover? Such a humiliating fate, being the bitch of another man, yet alone that for a horse demon. It was so wrong. Yet… Why did it make Shujinko feel so good the more he thought of kissing that puckered hole like a wife would kiss her husband?

“I…” Shujinko’s brain was frying. “I want… I want to…”

A pause. Shujinko panted. He wrestled with his instincts trying to pull away. Then, finally…

SMOOOOOCH~! With wild abandon, Shujinko thrust his head into the sweaty flesh of the horse demon’s taint and pressed his soft lips against the beast’s asshole! Oh, what a thrill to finally give in to that instinct! All of that hesitation was gone the moment he crossed that threshold and kissed a demon’s nether regions as passionately as a bride. He pressed his face in deeper! He couldn’t deny it now; he was a full on cock-loving horse slut!

This was a delight no mortal man was built to stomach. Shujinko felt like he needed more of this dark delight the moment he broke away from his long, passionate taste of horse ass. Another kiss, farther south this time, pressing his maw against the expanse of taut skin that trailed down to Gamigin’s heaving baby factories. The kiss broke down just seconds in. The pheromones coating this horse ass were just too intense! He needed it on more than just his lips, he needed those sweet oils staining his skin, claiming his body with the fragrance of horse sex!

Kissing turned to frantically rubbing his cheek against the expanse of stallion crotch, trying to fully overwhelm his senses in the delight of that degrading demon aroma. His nose was snorting as frantically as it could. He was flat out addicted in seconds!

All the while, the dark demon smugly sat and purred, amused at just how easy mortals had become to break. Gamigin’s massive cock steadily flushed full of blood as the so-called hero continued pampering horse ass.

“Fuck. Fuck! It’s so good! You smell so good!” Shujinko praised, taking deep huffs of that intimate zone.

Shujinko had fully lost control of his body. Shame was the last thing on his mind; he felt far less like a weakling who’d given in to a demon’s temptation and far more like a greedy buffett patron determined to make the most of their time. As Shujinko’s face wreaked of equine, as the odor of that beast’s sweaty backside and his smooth skin became indistinguishable, Shujinko moved on to sate another one of his senses. Taste. He had to feel that delicious phermonic cocktail overpower his taste buds!

“Maaah~! Maaaaah~!” The broken hero mewled like a horny animal as his tongue lapped across the expanse of sweet skin.

That taste… what a rollercoaster of an experience. The bitterness made him nearly wince at first, but the insidious inherent darkness of a demonic body cured his ailment just moments later. That nefarious power far too brutal for human contact twisted his very sense of taste into craving nothing but the flavor of sweaty horse balls. A second lick and he was wide eyed and delighted. The third, fourth, fifth, and endless flurry thereafter had the cyber horse bitch open faced sucking on taint like a leech, cleaning every inch spotless with his writing tongue.

Shujinko was in heaven. He only wanted more. Once the taint was clean, his face sunk to motorboat balls. His cheeks puffed wide as obscene noises leaked behind the stallion’s ass. Shujinko savored each moment caressing those giant sperm factories. And once those were fully polished, his face rose to kiss that asshole as expansive as his face in a more full and ture embrace. He sunk his tongue into that clenching pucker and wriggled around his muscle inside the asshole of that fell beast vigorously.

Gamigin at this point was earnestly aroused himself. His length had seldom felt the touch of mortal flesh in millenia, and this one had fallen to his demonic touch so effortlessly. It was time to take things even further.

“What a pitiful display, mortal.” Gamigin insulted.

The beast read the boy well, stinging at his masochism to further its goal. “To think you claimed you could resist me. Now, I’m sure you can realize you’re nothing more than a filthy pervert.”

Shujinko came up for air from his trip diving beneath demon ass. “I’m sorry sir! I should have known I was just an absolute horse slut!”

“That you should have.” Gamigin remarked. “You must be punished for your insolence. Kneel.”

Huffed up on horse pheromones, Shujinko had no interest in anything but total obedience. He did as told, sinking to the sand below on his knees.

“More.” Gamigin demanded. “Put your face and hands to the sand. Raise your bottom.”

Shujinko’s eyes went wide as he realized what was being demanded of him. “I… I…”

“Hold your insolent tongue.” The horse-like demon rang, trotting into position behind the boy. “This is no time for defiance.”

He’d been misread. Defiance was the last thing on Shujinko’s mind, his heart was just aflutter with excitement! The fallen hero got into position, face low, ass high. His hands reached back and tore open the backside of his outfit, exposing his erect cock and unprotected asshole to the arid air.

“I am honored to be your mare, sir.” He happily chirped.

Gamigin paused at that remark. A grunt escaped the beast. An enthralled, passionate grunt unlike that cool presentation the demon had kept up.

“You… You are too much! I must claim your male folds as my own! NNNNRGH!”

The beast stomped forward, rushing up against Shujinko’s backside and eclipsing the boy beneath him with reckless speed! In a flash, Shujinko was beneath the demon, horse legs on either side of him with a heavy extremity tapping at his backside! He smiled bright as he could.

“Claim your horseslut! Breed me for all I am worth!” Shujinko cheered. “Show this poor mortal boy how demons can-AAAH!”

Shujinko went silent as Gamigin claimed what was his. The gigantic, hand-thick horse cock prodding at his back door, that impossible arm-worth of cock that surely could never fit inside him… entered. It slipped in, lubricated by some unknown magic or other means. Impossible amounts of dick were diving deeper into Shujinko’s forbidden hole. It felt so insanely huge. It felt as though Shujinko might break in two any moment!

The situation smacked Shujinko. He realized what exactly was happening. “I’m… I-I’m losing my virginity to a horse…”

For a second, it felt like perhaps shame had the soil to once more take root. There was a window for Shujinko to revolt against this debauched display and reclaim whatever tattered shreds of his dignity were left with some miraculous escape. Yet, he did not. He saw the window, he felt that itch to revolt. He also felt something else, far stronger than those feeble human social pressures figuratively mounting him. He felt the strength of a demonic beast literally mounting him, pleasing him like a lover, treating him like a total bitch. Every moment that steed cock sunk inside him, every inch that passed against his prostate, teaching the curious boy the power of the male love button, felt like the definitive eye opening sexual experience of his life. And that was without the lingering odor of horse sex staining his face, dulling his senses, making him crave nothing more than subserviance to the strange demons roaming about this land. Maybe those were forcing him into demonic domestication earlier. Now though? He knew it felt far too good being a horse slut to reject in any mental state.

The beast grunted as near the entirety of its length entered Shujinko. The beast’s mighty balls pressed against the cyber femboy’s plump cheeks, equaling his girly hips in size. Shujinko loved every second of it. Being filled, being used, being nothing more than an object for a demon to claim was making him as erect as he’d ever been!

“Fuck me.” Demanded Shujinko.

“Speak louder, boy.” Retorted the demon.

Shujinko abandoned all shame! “Smash me! Ruin me! Breed me like a mare, I need it!”

The beast answered the plea in kind! With a roaring grunt, Gamigin’s steady insertion into the boy’s virgin hole turned into unrestrained, unbridaled ass breeding! The beast worked at a speed a desperate horse in heat would summon for its most vigorous sessions. It was far faster and far harder than the human body could withstand! Shujinko turned into a roaring mess, tongue lulled out, hands and face pressed against the sand, ass raised high as his poor cheeks withstood the full wrath of a horny demon.

Plap-Plap, Plap-Plap, Plap-Plap. Over and over those heavy balls spanked Shujinko’s fat ass!

It was a miracle he could withstand this assault at all but… my god it felt GOOD. It felt better than good, it felt fucking amazing! Even with the pain of having his ass stretched to an insane diameter, he was in far more pleasure than anything! Each thrust of horse cock in and out of his insides felt like someone punching his prostate with force. It felt divine, like he was a beast as well, just being milked of his seed in a very different way.

Bless whatever dark magic was keeping this encounter going. There had to be some sort of magical machination shoving that much cock in his pussy, right? Every time it sunk into him, he felt so impossibly full, body overwhelmed completely. The sensations alone were so much to process, it was all that was filling his horse-drunk brain! He felt almost like a sentient sex toy, as if his only purpose was to be a warm, wet, disposable hole for horse cock!

Shujinko begged for more. “M-maha… a-aaa…”

Or, well, he tried to beg for more. His poor lungs were running so tight on air keeping his racing pulse going, they didn’t have time for frivolities like speech. Perhaps it was best that way. Maybe if he were a bitch for a horse, he should only be able to respond like an animal. Instead, Shujinko tried to summon all his strength into his ass muscles to try and convey some message to Gamigin. He clenched his butt hard, or as hard as his rapidly numbing anal passage would let him flex such a muscle.

The beast read the message in kind. The pace turned full throttle!

Plap-Plap-Plap, Plap-Plap-Plap, PLAP-PLAP-PLAP! Those bulky horse hips thrusted with reckless speed! Gamigin’s true nature as a dark, lustful demon came roaring out as he gave into the sweet touch of modern human boypussy!

Finally, Shujinko found the will to speak. “Hooo…. H-hoooo~! Fuck meeee~! Breed me like a bitch, you fucking giga-cocked demon monster!”

Shujinko’s legs twitched. If he were with a human lover, his knees would be clamping around hips in a leg lock, determined to get knocked up. Instead, his twitching calves just sunk him a little deeper into the sand as demon cock railed him hard. He was so close to climax… his first ever sex and he was about to cum handsfree from getting railed by a horse! Fuck, it was humiliating. And fuck, did that humiliation ever get him even harder!

PLAP! One final thrust in! The demonic beast let out a roar of unparalleled relief. Climax was here! It was ejaculating!

Shujinko could feel the beast’s peak outside his body before a single squirt fired. He could feel that leather ball skin rub against his spotless bottom as those impossibly mighty balls flexed upward, contracting the potent load of horse spunk and priming it all to fire.

Then… “O-OOOH~!”

Shujinko couldn’t help but yelp as an absolute enema of steaming hot cum blasted his insides with force! In moments he felt beyond stuffed. Soon after, semen was backwashing out of his ass. And still, the beast kept pouring the stuff inside him! Shujinko felt like a water balloon being filled. There was such a huge volume of sperm, he could feel his insides squelching and glugging like a huge container being filled with water. He was a condom for this ferocious beast, his tummy even bulging from how impossibly full his stomach had become!

This was too much. Shujinko couldn’t hold on. With torrents of cum racing against his prostate, he lost control. His still semi-limp cocklette started to dew and squirt strands of white, dribbling against the sand below. His first anal orgasm in such a horrid place to such a disgusting demon… How wonderful.

Shujinko was exhausted as the deluge of spunk and his own orgasm finally started to come down. His post orgasm clarity was starting to tilt his thought process back in a reasonable state of mind, though notably stained by the lingering aroma of horse balls.

Yet, as Shujinko recovered, he started to notice something. There was no shadow of a beast atop him. There was no powerful horse figure around him. He seemed to be alone, at least at first. Then, he took a closer look behind him.

Gamigin had been reduced to his essence, no more than a purple flame with some red hint of eyes inside the fire. This was… wasn’t this what demons looked like in their last moments before sacrifice for a demon fusion? Had he really tuckered such a beast out to expend all its energy and be no more than inventory just for some good makeshift pussy?

Hmm. Maybe having a thing for demons was less an embarrassing flaw and more another useful tool.

Risking battles versus instant kill spells like Mudo increasingly didn’t seem like the right approach. Perhaps the best option exploring this land was to offer a little something in exchange for demonic alliances. After pleasing an ancient demonic horse god so thoroughly, Shujinko was confident his ass was more than just a little something. He’d have droves of demons under his command in no time.
