Chapter Text

Phainon lay on his stomach, his legs swaying in the air as he re-read his favorite novel ‘The Tyrannical King Loves Me Too Much!’, a nonsensical hentai-filled erotica his best friend Castorice introduced him to years ago. She said the male lead was exactly Phainon’s type, and she was completely right.

Warrior-King Mydeimos ‘The Undying’ of Castrum Kremnos; tall, crazily handsome, strong, filthy rich, obsessed, and an absolute sex god. Titans, even on his fifth re-read of the novel, Phainon still felt shivers run up his spine from all the positions Mydeimos forced the main character into, bending him in all sorts of ways, fucking him wherever and whenever he pleased, making sure everyone in that damn palace knew exactly how much he pleasured his war prize-turned-wife. He was so forceful, so dominating, so insatiable. The official art only made Phainon drool more: rippling abs, biceps thicker than Phainon’s head, sharp jawline and defined cheekbones, a thick blonde lion’s mane of hair that tipped blood red, and his eyes—oh his eyes. So predatory, bright gold, and intense, like he wanted to devour the person he was staring at.

It was almost a nightly routine for Phainon to get himself off to thoughts of Mydeimos, fingers digging into his cunt the way he imagined the man would do, jabbing up into his core mercilessly, going even after he orgasmed and sending himself into oversensitvity. He had an almost shrine of fan merch: plushies, posters, fan art, key chains, doujinshis—you name it, Phainon had it. It was almost an obsession, one-night stands didn’t do it for him anymore, none of them were Mydeimos, none of them looked like Mydeimos, and it completely put Phainon off. He even ended up calling out Mydeimos’ name while getting an unsatisfactory dicking, wishing the man on top of him was the fictional king.

His favorite possession was the dildo he commissioned in the shape and size of Mydeimos’ cock. It was ridiculously huge, as all hentai male leads were. 12 inches long, 9 inches in girth with a fat head and veins running along the shaft. He even paid extra for it to have a suction and motor, 5 different vibrations and the ability to thrust back and forth in 3 speeds. He got it colored like Mydeimos’ cock too, tan with vibrant red tattoos that ran around the length and pulsed in color when he used it. It cost a pretty penny, but the mindblowing orgasms it gave him made it worth the price. There was one very memorable time he accidentally dropped the remote after he came and the dildo fucked him past his limit until his eyes were rolling up and he passed out—just to wake up with the dildo still pistoning in and out of him at maximum speed and maximum vibration. His bedsheets ended up being soaked in his releases and even four washes couldn’t get the stains and smell out. His pussy had been sore for days, still leaking uselessly every time he sat down and felt pressure against it. He almost got it with a pump chamber, but he didn’t want to have to wash lubricant out of himself every time he used it—which was every night. It wouldn’t even be the real thing anyways, so he skipped over that modification.

So yeah, you could say Phainon was crazy about Mydeimos, who didn’t even exist. Which was why he was often so annoyed with the main character, whose description actually sounded like Phainon to a T. He definitely wouldn’t act like them though, so resistant and holier-than-thou towards Mydeimos until he got fucked senseless. It took almost ten chapters for the main character to finally fall in love with the king—Phainon could do it on the first page!

He closed his book with a dreamy sigh and rolled over onto his back. “Mydeimos…” he murmured, his eyes dazed as he thought about his love. “If only it were me…” His eyes slowly drifted shut and as darkness crept over his mind, he felt a rush run through his body before he went limp.

There was a hand lightly touching his shoulder, shaking him awake. “Princess, please wake. It will be only a few minutes before we arrive.” Phainon made a little noise, his nose scrunching as something brushed against it, thin and lacey. He felt himself sitting up, slumped against something hard as his head rocked with gentle movements. He heard the sound of hooves clopping and smelled grass and animal fur.

Where… am I? He thought to himself, his eyes fluttering open as he registered the fact that he wasn’t on his bed. There was a white veil over his head dropping down to his sternum, and as he smoothed his hands over his legs, he felt a silky material caressing him. He looked down and saw a medium-length pure white dress on him—if it could even be called that! It was an off-the-shoulder dress with large diamond shapes cut into the sides, baring his waist and hips for the world to see, and it was so thin, his skin shone through it in the light, slits running up both sides of his thighs that almost completely exposed him if not for the part that draped between his legs—brushing against his bare cunt!—and a chest window so open his nipples were on the verge of bursting out. It was skin tight, every single curve of Phainon on an obscene display, and his cheeks flushed when he saw his nipples stretching the fabric, the pink mounds teasing through the material.

He looked to his side and saw a girl sitting a polite distance from him, her hands in her lap as she kept her eyes lowered. “Good afternoon, Princess. We are moments away from Castrum Kremnos and the king has personally deigned to escort you.”

Phainon’s mind screeched to a halt. Castrum Kremnos? Princess? King!!!! His breath hitched. No way. There was no way he was that lucky, right? Phainon bit his lip to keep in a squeal. Calm, Phainon, calm! Let’s just wait and see. He nodded lightly, his veil swaying with the motion as his heart pounded.

This was a scene he read over and over again. King Mydeimos fell in love at first sight with an ordinary Okheman soldier fighting on the battlefield, and after Castrum Kremnos won the war, the one non-negotiable King Mydeimos set was for the soldier to marry him. Of course, the main character hadn’t wanted to go—in fact, he protested and fought against the decision until the elders decided to drug him and dress him up in clothes King Mydeimos sent over before shipping him off. When the main character woke up, he caused a commotion and publicly rejected the king who had personally come to fetch him. It was a whole thing that Phainon rolled his eyes at even to this day.

But Phainon? Oh, there would be no fight from him. If anything, they would need the entire Legion to pry him off of King Mydeimos’ fat cock! His body trembled in excitement and the girl spoke again.

“Please don’t be scared, Princess. The king might be a bit forceful… and a little intimidating… but he’s also… um.” She, with the purest of hearts, thought his trembling was from fear and tried to comfort Phainon, but paused as she tried to think of positive things to say.

King Mydeimos can be as forceful with me as he wants!! Phainon screamed in his mind, reaching out to place his hand over hers, squeezing gently before pulling away again. She smiled at him, flinching as the carriage rolled to a stop. Phainon took a deep breath as the door was opened by a servant, and as he placed his foot on the step leading down, a large calloused hand appeared in his view.

Phainon swallowed, his eyes shaking as he looked and saw him. Ah… King Mydeimos… His love made flesh, standing right there! In front of him! Holding his hand out and waiting for Phainon to take it, dressed as he always was with half his deliciously toned chest on display, his black trousers tight against his skin as his crotch bulged out, his thighs straining against the material. Phainon had to clamp his mouth shut to keep drool from leaking out.

He lifted his hand up, and it shook from anticipation as he laid it on King Mydeimos’, shivering at the warmth seeping into him. He was touching King Mydeimos! This was real!!!

Thank you whoever sent me here!!!! Phainon screamed in his mind. If I ever find out who you are, I’ll build a temple in every nation in your image!!!! Using my handsome, monster-cock having husband’s money, of course!

A small smile curled at the corners of King Mydeimos’ mouth and he spoke, his voice deep and intoxicating like a rich aged red wine. “My bride, you have arrived.” He lifted Phainon’s hand up and pressed his lips to it, soft and plush. Phainon’s heart skipped a beat and his breath hitched.

King Mydeimos looked at him again. “You’re shaking.” He murmured, stepping back to let Phainon exit the carriage. Phainon almost stumbled and a muscled arm shot out, wrapping around his waist and pulling him flush against a thick chest, King Mydeimos’ burning hot skin touching Phainon. “Do not worry, I will be good to you.”

Shaking from excitement!! Phainon thought to himself, nodding at the man. “Yes, King Mydeimos.” He said quietly, keeping his voice soft and trembling. That large hand around his waist started acting dishonest, squeezing plush flesh into his grip and his fingers sneaking into the cuts in his dress, grazing his stomach and pressing into the softness. Phainon pressed his thighs together, heat pooling in his gut.

“Mydei.” The king said, his eyebrows furrowed. Phainon wanted to smooth the crease from him. “My Queen-to-be does not need formalities with me.” Phainon almost squealed. His queen! Phainon was—is—his wife!! Phainon praised whatever entity brought him here even more fervently and leaned his head against Mydei’s shoulder, taking small breaths of his scent. Pomegranate and cedar filled his nose, and Phainon couldn’t believe he was actually getting to smell it directly from Mydei instead of having to imagine it!

That hand kept caressing him, drawing out from his side to slide down to his ass, slipping underneath the slits of his dress to grope him, sneaking to his inner thighs and pressing up against his wet cunt. “So responsive.” Mydei whispered into his ear, his fingertips inching inside as Phainon let out a breathy moan. The king let go of his hand and grabbed a handful of his tits, Phainon’s nipples spilling out into the cold air as the dress was dragged down from the force of his grip. “And plump.”

“Mydei…” Phainon’s voice came out high and whiny, his hands clutching at Mydei’s shoulders as he squirmed in his hold. A deep chuckle echoed in his ear and he let out a yelp when Mydei picked him up by the ass, his legs instinctively wrapping around his thick waist. He whimpered when his cunt spread open and pressed against the tent in Mydei’s pants, pushing the fabric of his dress and the bulge between his lips and soaking it in slick. Mydei started walking and his steady gait rocked Phainon on him, grinding against him again and again as Phainon buried his face into Mydei’s neck, breathy sounds escaping him.

Phainon hadn’t stopped leaking since Mydei touched him and he could feel it dripping out of him, his chin hooking over Mydei’s shoulder and seeing little droplets on the ground like lewd breadcrumbs. The king strode through the palace, his footsteps slightly hurried as he barely acknowledged the servants bowing to them, his hands tightening almost painfully on Phainon’s ass.

Mydei lost his patience after a while and turned to pin Phainon against a wall, his hands sliding to hold onto the back of his thighs as Phainon sunk down the wall, his face level with Mydei’s collar. “Never once did I think my palace too large until it kept me from feasting on you.” Mydei growled in his ear, burying his face into Phainon’s neck and nipping at the sun mark sitting there. One hand reached down to unbuckle his pants, the sound of metal clinking making Phainon’s blood rush.

He was about to experience the real thing!! His heart raced and he tangled his hands into Mydei’s hair, sinking them into thick softness. Mydei’s other hand snaked between his legs from behind and fingers spread open his cunt, Phainon letting out a quiet gurgle when the fat head of Mydei’s cock pressed into him, his cunt suckling on the tip, and Mydei grunted between gritted teeth. He smothered Phainon further into the wall and thrust his hips up without pause, prying Phainon’s core open and molding it to his shape.

Phainon seized around the girth and squirted, his wetness spraying out from the seams of his stretched cunt, drenching Mydei’s thighs and the ground around them. The air filled with the smell of musky sweetness and Mydei opened his mouth to breath it in, his eyes blazing golden. “Whorish wife.” He purred, setting a punishing pace, his hips drawing out to smack loudly against Phainon’s cunt and balls heavy with cum as they swung in the air. Phainon clawed Mydei’s back desperately, his nails sinking into flesh as searing heat buried itself into him. Each inch scraped against his walls and Phainon was stuffed so full he could feel every vein pulsing on the length.

Mydei fucked him through another orgasm, ripping the veil off his head and tossing it to the floor, his hand gripping Phainon’s chin and yanking it up, predatory eyes raking over his blissed out face. “Truly a beauty to start and end wars for.” Mydei said, leaning down to press their mouths together, his teeth sinking into Phainon’s bottom lip and making him open his mouth in a gasp he never finished as Mydei forced his tongue inside, ravaging Phainon with loud slurping noises, their combined saliva slipping down Phainon’s chin in stucky trails.

Phainon clenched down on Mydei’s girth as hard as he could and smirked when the king let out a muffled growl, his hands latching onto Phainon’s hips and yanking him down, the flimsy material of his dress ripping loudly in the air. Phainon’s legs flailed out and his body thrashed as hot cum spurted into him, coating his walls with thick sperm while shredded fabric floated to the ground, leaving him bare from the waist down. Phainon let out a whine as cool air brushed over his newly exposed skin and Mydei pulled away, his hips pushing foward to hold Phainon up on his cock alone. Phainon dangled there helplessly, his hands pressed against his distended stomach and feeling it push up at his touch as Mydei just—kept coming. He couldn’t even see his cunt when he tried to look down and, oh Titans, would Mydei ever stop cumming inside him? The power of a hentai male lead was truly incredible, Phainon thought numbly, his eyes crossing and his mouth dropping open in a pretty ‘o’ as Mydei watched him, a perverse gleam in his eyes.

The king reached his hand out and raked his nails down Phainon’s middle, his dress parting like knife through butter and falling into scraps around him. Phainon was now completely nude, pinned up against the wall by a monstrous cock stretching his pussy lips thin and pink, with a stomach so large he looked three months pregnant—right in the middle of the palace’s hallway, where Phainon could hear multiple footsteps getting closer to them.

Mydei didn’t seem to pay attention or care about the approaching group and nodded his head in satisfaction. “My masterpiece.” He said, trailing his sharp nails along Phainon’s neck down to his tits, squeezing the flesh between his hold and pinching at the plump nipples, Phainon flinching as the pain of Mydei’s nails shot through him. Mydei pulled out abruptly and Phainon let a wounded noise, his eyes watering as he felt Mydei’s cum gush out of him and hit the ground with a loud splatter.

No, why—” Phainon sobbed out, his hands reaching down to catch whatever he could and shove it back inside his cunt, his palms becoming coated in Mydei’s seed and dripping wetly from between his fingers. “So mean, husband.” Tears dripped down his face and a hot tongue licked it up, rough hands grabbing the back of his knees and yanking them up, spreading them to press against the walls beside Phainon’s head, completely baring his fucked open cunt, messy with seed and slick and dripping, to the open air. Mydei’s cock swayed forward and Phainon arched his hips, trying to catch the head in his aching hole, feeling it scrape against his clit and his open lips until he grabbed the base with his hands and stuffed it back inside of himself, vision whiting out from being split open one more time and Phainon sprayed all over Mydei, his slick drenching the man’s torso and catching his chin—all to a wicked smile on his husband’s face as a tongue swiped out to lick it up.

“Absolutely perfect.” Mydei purred, slowly rocking his hips into Phainon as he bit all over his neck, nibbling on the lines of the sun and licking the red marks he left. “My one and only wife, my Phainon.” Phainon jolted and his cunt squeezed down on Mydei’s cock, biting back a whine as Mydei cursed and slammed into him, their chests flush together as he was crushed into the wall.

The main character’s name wasn’t Phainon. That was his name. Did that, did that mean Phainon replaced the entire charact—a wail ripped out of his throat as Mydei noticed his absentmindedness and sank his teeth into Phainon’s neck as punishment, breaking the skin as blood trickled down the curve of his neck and the swell of his chest.

“Do I not please my wife, to have him distracted while I seed him?” Mydei’s voice was low in displeasure, rumbling in Phainon’s ear as he pressed Phainon’s legs almost painfully into the wall and his hips started aching, stretched open beyond what he was used to.

“No, I didn’t, I didn’t mean to—husband, please—gentle!” Phainon thrashed under the heavy crash of Mydei’s hips against him, his cunt pried open and gushing out his arousal even as Mydei ignored how it clenched down on him in an attempt to slow him down. Phainon’s eyes were teary with pleasure when he saw Mydei look to the side from his blurry vision, his strong hips still pistoning in and out of him with loud slaps. “Take my bride’s belongings and sort them in my room.” Over his own cries, Phainon could faintly hear a servant responding before seeing a group of them hurry past the couple while holding the things Phainon brought with him. Phainon clawed at his back again and Mydei turned his attention back to him, chuckling at the petulant look Phainon sent him. “Apologies, my beloved,” Mydei said, leaning in to kiss him. “They would have stood there until we finished without my instructions.” His cock drilled into Phainon’s cervix battering at the tight opening until it was pried open, shoving itself in with a loud pop! and Phainon crumbled, his body seizing up around his cunt as his eyes rolled up and his tongue dropped, Mydei sucking it into his mouth and grinding his hips up more, bottoming out as he came inside Phainon again, pumping more seed into him until it was almost painful, the excess dripping out from where they were sealed together.

Phainon heaved desperately, his chest pumping up and down as the edges of his vision blurred and he twitched in Mydei’s possessive hold. Oh shit, I think I’m about to— Phainon’s eyes rolled up and he went limp against his husband, the feeling of cum still steadily shooting into him like a firehose the last thing he remembered.
