Work Text:

Despite his closeness with mortals, visiting their realm was not something Johnny Joestar particularly enjoyed.

Maybe decades ago, while he was young and everything was new, he had enjoyed it, maybe even loved it. It was about the thrill and the pleasure of slipping into the dreams of lonely, depraved women. But his youth was temporary, and so was that enjoyment. Mortals climax too quickly, break down into sobbing moaning messes with the faintest of touches before Johnny could take his own pleasure from them.

Now, he hunted only for the necessity of it.

He always hunted on starless nights. No annoying lights were needed. They only distracted him from discerning which heat signature looked more promising. When he found the one, he slipped inside the place through its window.

"Jackpot." Johnny's eyes glinted at the sight before him.

The man laying in the bed had to be one of the most beautiful humans Johnny had seen in a long time. Gorgeous long blonde hair, and a handsome angular face with a bit of facial hair. Johnny can't say he'd seen other humans with that style of beard cut but what did he know about their habits. The real thing to look at was the man’s physique. He slept shirtless and without covers, leaving his toned arms and firm pecs for Johnny’s eyes to shamelessly feast over.

Johnny approached the man and pressed a palm to his crotch.

...Holy shit. A full-course meal.

He usually didn't go for men but once in a while it was good to have something different.

Johnny crawled over his prey, seating himself over the human's hips. The scent of lust began to fill the air, making Johnny's mouth water. He pressed their foreheads together and pried through the man’s mind, following that scent into his subconscious and...

Nothing.

The darkness around Johnny wailed, overwhelming him. Johnny pressed his hands to his ears just as a force yanked him back and out of the plane of dreams.

He felt himself get thrown. Pain shot through his back as it hit the wooden floor, but the pain didn't have time to register in his brain because just then, an unknown, deep voice sounded directly into his ears:

"And what do we have here?"

There was no possible way... It was impossible for a human to break free from the spell!

Johnny clenched his jaw. Unless…

Luminous eyes stared at him, one green, the other golden. Johnny stiffened as he found himself afraid of the same handsome face he had admired earlier. Ridged black horns with highlights of neon green grew from the man's — not a man — head at either side, curling forward just slightly. Below the left golden eye sat a golden symbol in the shape of a cross, and that was when Johnny realized his mistake:

He had accidentally preyed upon one of his own kind.

Johnny didn’t hesitate. Crawling back to hell on an empty stomach would be the lesser evil, but that other demon wasn't going to let him off without getting something in return. He yanked Johnny's tail back before Johnny could dive into the portal he called using the last of his strength.

“Let go of me! Just who do you think you are?” He snapped, baring his fangs, readying for a fight until he caught the overwhelming blast of energy that almost sent him reeling.

Johnny hit the floor with a thud, trembling from the aftershocks of that oppressive energy. He turned to the other demon again and noticed the rapidly growing energy radiating from him. The difference in power was overwhelming, and Johnny bit back a whimper as his body froze in terror.

“I’m guessing you’ve realized by now, incubus,” the other demon — the exiled Prince of Hell — glowered at him, barring a row of sharp golden teeth. “Here I was, enjoying a good rest when someone breaks inside my domain and tries to nibble on my power.”

“Forgive me, I-I didn’t know—”

“Oh, I know you didn’t." Prince Julius pulled him closer by his tail, eliciting a whine from Johnny. "I don’t expect a weakling like you to even know the difference between a real human and a demon disguised as one.  It’s clearly beyond your capabilities.”

Johnny bit his tongue, displeased at being insulted.

"If you're gonna kill me, then do it."

"Oh?" Julius' expression softened some, but his eyes remained cold. "You're ordering me? Your own prince?"

“You were exiled. You've lost your title. You’re no prince of mine.”

Julius’ expression didn’t change but Johnny could see his anger in the way he lost control over his perfect disguise. Green-iridescent black scales grew over his fake flesh as he talked. “My power is still the same. I’m the one that will give you the final judgment so I advise you to choose your next words carefully.”

What was there to say? He was a mere lust demon from the second circle, nothing but an insect in the eyes of the true terrors that lurked in the depths of Hell. If he was going to be put off then, if anything, he'll make his final words count.

“Fuck you! Just kill me already!”

Julius blinked at him. Johnny saw the way his pupils compressed into slits and he braced himself for what was to come next. At least he would go down with honor, rising up to the creature he only heard in tales and quiet whispers. Julius walked towards him, his long tail following right behind in slow, deliberate movements. The tip was the shape of a scythe, curved and sharp and adorned in the same neon green that gleamed off Julius’ scales. Johnny followed its movements with his eyes, waiting for the moment it would swing towards his neck, but then, his face was forced to the side to meet his prince’s.

Julius bore a large golden grin, the same golden of the mark on his cheek.

"Ah, but I like your feistiness. I find it rather cute,” he purred as he caressed Johnny’s cheek. “Such a waste of a pretty face.”

Johnny shuddered.

“Are all of you Lust Demons just spawn with nice bodies?”

“Gotta fit the norm of what humans consider attractive and fuckable," he replied tightly.

“Hm. I find it attractive and fuckable.” The hand on his face trailed down to Johnny’s chest to toy with a pert nipple, pinching and twisting it between his fingers. 

Johnny sucked in a breath, feeling a new kind of heat rise to his face.

“What are you—” 

“And are all of your kind as impudent as you are, incubus?”

Johnny looked up at the large demon, mouth agape. The scent was back, stronger than anything Johnny has ever encountered amongst the mortals of this realm; it was almost overwhelming, this insatiable hunger for pleasure that rolled off the exiled prince like waves. Like he never had the opportunity to give in to his sexual desires in ages.

"Just me…"

“Oh? Then it’s my luck. What is your name, impudent incubus?”

He shouldn’t say it… “Johnny.”

“Well, Johnny, here’s my judgment to you.” Julius pulled him by the tail until he was partly sitting on his lap. “For your inconvenience to me, you must serve me for the night. If you do your duty accordingly, you will also be properly fed and I’ll let you go as soon the sun rises. How does that sound?”

Oh, so that was what it was. Johnny shivered when he felt Julius’ breath ghost over his neck, fangs scraping against the skin across his collarbone. He processed the words on his mind. Was Prince Julius messing with him? There was no way he would make such an offer to someone like him, he must have had some other goal in mind. But at that same moment, slowly becoming giddy from drinking in more of the wonderfully smooth energy Julius was giving off, Johnny couldn’t bring himself to care anymore. He hungered for it too.

“Fine. I can accept this punishment.”

Julius barked in what could only be described as a laugh. A very odd, very obnoxious laugh.

“Oh, Johnny… Is it really a punishment when you will be enjoying it?” He purred before sinking his fangs into the flesh of Johnny’s shoulder without warning.

Johnny arched his back and cried out in a weird amalgamation of surprise, pain, and pleasure. His eyes rolled onto the back of his eyelids and for a brief moment, he was numb.

When he returned to his senses, his body spasmed in the aftershocks of the dry orgasm he just experienced. From a single bite!

“Wha… What have you done to me..?”

Julius hummed against his skin, hot breath ghosting over the broken flesh and making Johnny jerk away from it on instinct. Demon skin was thicker than any other being's and only a select few weapons were able to breach through it. His prince's fangs were sharper and stronger than any weapon conceived by humans and angels and, somehow, that knowledge didn't scare him as much as it should.

"Don't worry. I'm not going to eat you," Gyro broke into a chuckle, "yet. This is merely a... contract. To ensure you don't go back on your word."

Johnny felt offended. "I wasn't thinking of bailing off. 'm not a coward."

"Well, you won't be leaving, either way."

Johnny watched with a mix of awe and fear as the torn flesh of his shoulder stitched itself together and burned until a neon green mark the same shade as the prince's claws was all that was left. It was shaped like a fleur-de-lis and it covered his own star-shaped mark. Johnny sucked in a breath upon recognizing it as the royal sigil. 

"My mark." Julius explained as he licked the excessive blood from the corner of his lips.

He pulled Johnny's tail back without warning, making the incubus yelp.

"Don't pull my tail!"

His complaint fell on deaf ears as Julius then leaned back into him. His large hands hold him by the sides of his chest, the tips of his claws teasing his nipples in gentle touches.

Beautiful.

Johnny stiffened. What was that?

"Me," Julius breathed onto the back of his neck, where his lips touched the skin lightly. You belong to me now. Body and mind.

Johnny's breath caught as he looked down at the way Julius played with his nipples. He leaned back against Julius, pushing his chest forward to try and get more of that stimulation.

The air shifted at that simple action. Johnny parted his lips and tasted his prince's lust. Rich and thick. A powerful flavor that made his entire body tremble like a leaf.

He felt the sturdy chest behind him rise and fall. The hands left his chest reached below to spread him open, exposing his rear to the open air. Julius rumbled deep in his throat as if he was just given an exquisite meal and then moved one of his hands to insert one claw into him without so much as a word of explanation. His thighs twitched in surprise, but he tried to keep them still.

Wanton. Julius' amused voice sounded within his mind.

Johnny's stomach dropped, and the back of his neck — where he knew Julius' gaze was — burned.

He twisted around, words ready on his tongue, but he forgot whatever he was going to say when Julius pressed a second claw inside him, down to the knuckle. Johnny lunged forward with a hiss but Julius didn't stop. His fingers pressed in deep, swirling around as though to feel every bit of him.

"I won't sugarcoat it to you, Johnny. I am much larger in this form and outside of the dream realm, there will be pain." What! "I want to make this as minimally painful to you as possible."

He fucking better.

Julius laughed again. "Your thoughts are even snappier than your mouth."

The larger demon reached around to grasp his half-hard length in the entirety of his palm and squeeze it.

Johnny bit his lip to keep from making any noise. He was still recovering from the first orgasm so his cock was so sensitive even the slightest pumping motions of Julius's fist were too much he could hardly bear it without crying out. But then the larger demon's fingers resumed their movements inside him, keeping them at the same pace of his strokes and Johnny couldn't hold back the small whimper stuck in his throat for much longer.

C'mon. Sing for your Prince. Johnny began to pant, his thighs tensing. Large yet gentle claws scissored his insides and rubbed the leaking tip of his cock, spreading wetness around. Johnny could feel the pressure building in the shape of tingles shooting from his lower belly up to the tips of his claws and horns. His own arousal was so large he was feeding on Julius' energy in huge chunks, though his prince didn't even seem to notice.

But then Julius crooked his fingers upwards, stroking and sliding in and out to relentlessly hit that spot.

"N... Ha- aah!"

The pressure was relieved all at once, Johnny's entire body curving like a bow. He could no longer control the little sounds that slipped out of his lips with each breath he took. His forehead hit the floor where he stared at the floor.

In contrast to his drowsiness, though, Julius gained a newfound enthusiasm, —  How cute; So quick; Hope you're not tired yet; I'm not done with you! —  all at once, his thoughts evaded Johnny and kept him from formulating one of his own.

He wasn't given the slightest moment of rest before Julius was touching him again —  the sharp sensation of his tail being pulled up with too much force followed right after by the very warm feeling of his prince's tongue sliding up his rear.

"Haah... wait—" He shook his head and whined, reaching back until his hand found one of Julius' horns.

He gave it a forceful tug, to which Julius replied with a growl and another sharp pull on Johnny's tail. This time, Johnny's eyes stang with tears. Behave!

"Then stop pulling my tail! I'm sensitive there!" No point in keeping things to himself when Julius could hear him anyway.

Julius raised a single bow at that statement and then smiled. He pulled Johnny's tail again, and another embarrassing noise slipped out of him.

"Stop!" Flustered and moved by anger, Johnny reached for Julius' own tail and pulled it.

Big mistake.

Julius didn't even feel that, only looked at Johnny with more amusement in his eyes.

"Such disrespect. No wonder you got yourself into this predicament." The slight twitch of the muscles of Julius' thick tail under his palms was all the warning he got before the appendage wrapped itself around him in three curves and pulled him into the air. "Fate brought you right to me so you could finally be taught your place."

Johnny grit his teeth and tried to break free from the tight grip of that tail but it was fruitless. He slammed back down onto his back. Julius wasted no time climbing over him, lifting his knees up and apart as he settled himself between his legs.

Saliva gathered in Johnny's mouth and he tried to look down at what Julius was doing but the sharp tip of the larger demon's tail was firmly pressed beneath his chin, preventing him from doing such.

"You don't get to watch," Julius announced darkly. "Until you prove yourself worthy, you will lay there and accept whatever I give you."

The hot, blunt head of a cock was suddenly being pressed against his hole, and then dragged up and down. Johnny clenched his jaws, hyper-aware of the sensation of Julius' thick shaft and all its ridges. It was then he came to the realization this would be his first time having sex with another demon. A demon who is much, much larger and powerful than him.

He felt as if he couldn't breathe, his whole body freezing up once Julius' cock finally slid inside him.

"Hng—”

Johnny squeezed his eyes shut, the tears finally rolling down his cheeks. His face burned with what could only pin on shame for acting so disgracefully in front of his Prince. The tip of the scythe on Julius’ tail pressed up on his chin the further the cock inside him pushed further inside, making Johnny tilt his head back. Something must be wrong with him. He should not be reeling with pleasure just from the feeling of being stretched by a thick cock.

“Hng— aah… aah…” But Julius felt so hot inside him. There was practically no discomfort, only the acute feeling of his walls being scratched by the ridges of the prince’s cock. “Wait—”

Johnny whimpered, and then took a gasping breath when Julius pulled out and then pushed back in, building up a slow pace. Something was coursing through him. Something hot and electrifying. With each thrust of Julius’ hips, he felt as if he was being torn open further.

Tentatively, he opened his eyes and took in the focused frown on Julius’ face. The prince looked as if he was restraining himself. Forcing himself to keep going slow and going on his promise to make this as less painful to Johnny as possible.

“Nyoho, to be honest with you,” Julius opened his eyes the slightest bit, “it’s also my first time doing it with a demon… Ngn—

Julius’s words were interrupted by a growl of his own and he picked up the pace to an alarming degree. Johnny’s eyes widened but he was still trapped into the same position by Julius’ tail, unable to even look down at the cock currently pushing into him. 

“You feel so good around me, Johnny.” Julius panted, a wild gilt to his eye.

It was brutal. He was being thrusted into so quickly and so deeply. Julius was wildly taking his own pleasure from Johnny but it felt so good. Yeah, you like being used, don’t you?

The pressure left his chin and he instantly looked down, mouth agape, and eyes looked on the way Julius’ impossibly large cock sheathed itself inside him almost fully. Nine Rings, it was so big! It was so powerful! Yeah, you fucking love my cock, don’t you?

Johnny squirmed, unaware of the noise he was making until Julius finally came and his body felt like it was burning from the inside out. With a final grunt, Julius pulled out and Johnny almost, almost whined at the feeling of emptiness.

Insatiable. Julius was back at lining the head of his cock to Johnny’s entrance, except this time the smaller demon could actually see it — large and thick and ridged as he’d felt, covered in smooth scales of the same colors of his horns and claws. It made Johnny’s mouth water. Cock-hungry slut.

He shuddered, feeling as if something inside him just broke.  

“M-My prince…”

“Oh, polite all of a sudden?”

There were no more words, no further contemplation of how debauched he must look in the eyes of his prince, when Julius pushed inside him, faster and harder than the first time. He began fucking Johnny with no further build-up. The only thing keeping Johnny from being flung over by the force of his thrusts being the tail that’s still curled around his frame. Johnny’s head fell to the side as he was unable to focus on anything else except the short periods in which Julius’ hips snapped against his own and the drag of that cock in his insides.

“My prince!! M-Mercy—!” He shouted as he came for the third time that night, body trembling with the spams of being fucked through orgasm. 

It didn’t take much longer until Julius followed right suit. His hips still while he’s buried deep inside Johnny, rolling them and whining into the back of his throat as he came inside him again.

His prince didn’t pull out of him. His cock was totally different from a human’s even down to the biology of it. It remained hard even after its release and Johnny was practically sobbing with the way it prodded against his oversensitive insides as Julius lifted him back into the air with his powerful tail.

Julius lounged back against the side of his bed, legs spread and cock ready as he lowered Johnny back into it. The new angle made it reach even deeper if that was even possible. Johnny sank his claws into the demon prince’s chest on reflex, eyes wide and glossy with the strain. Julius grunted in complaint but did nothing. If this manages to give you some comfort…

It did. That solid, real feeling tightly clasped in his claws gave him all the comfort he needed.

“Looks like I worried for nothing by thinking you would leave.” Julius cupped Johnny’s cheek in one large hand. His claws gently scratched the skin behind Johnny’s pink horns and he mewled, leaning into the touch.

His other hand clasped underneath Johnny’s bare bottom to lift him up until only the tip of his cock was inside him. His tail wrapped beneath Johnny’s knees before thighing, bringing them up to his shoulders until he was being practically folded in half.

Julius purred, continuing to scratch behind his horns even after making Johnny bounce on his cock with his tail. The other hand left his ass to wipe off one of the tear trails from Johnny’s face.

“Yo-your highness— I can’t hold it for much longer!”

“Yes, you can,” he said, firmly. “I know you can, gattino," he added right after, softer.

Johnny shook his head, tail whipping the air. Julius continued caressing his face as he bounced Johnny on his cock, wiping away at the fresh and dry tears in his heated face. One of his thrusts hit Johnny just right and Johnny felt as if he couldn’t breath. His eyes widened in terror when he felt the familiar pressure on his stomach.

With a pathetic whine, he came again, body going limp in Julius’ hold.

Julius leaned down to kiss his cheek. He was saying something Johnny couldn't understand. Couldn't care to. All he could think while listening Julius tall, was how rich, how deep, how sweet it sounded to the ears. How it made something flutter in his chest. A feeling he'd only experienced when he was young and everything was new. 

He felt Julius stiffen under him, then a sound that could only be described as a purr sound from deep within the demon prince’s chest as he leaned forward to press his forehead to Johnny’s. Do you love me? I think I might love you too.

It was all so unlike anything he has experienced before.

“Well, what we're feeling sounds a lot like what humans call love..." Julius whispered and Johnny swore he could see the slightest tone of red on his cheeks. “But that's a just human thing.

He felt the tail loosening around him until he was only being supported by Julius’ large hands on his hips. Julius’ purring only seemed to grow stronger as he came again, nuzzling into the crook of Johnny’s neck where he had left his mark. He licked at it and Johnny jolted, his own tail whipping his prince’s arm on instinct.

Julius laughed against his skin, breathless. Their tails curled together as he tilted his head back to look into Johnny’s unseeing eyes.

“Your highness…”

“You’re drooling." A large claw wiped the corner of his mouth. “Cute. You’re very cute, Johnny.”

Julius leaned forward, catching Johnny’s lips with his own. 

Johnny felt that heat back on his chest, on his face, on his neck, everywhere. Tentatively, he repeated the motions of Julius’ mouth and tongue. He slipped his tongue inside the prince’s mouth and gently sucked on his. He knew what this was. A kiss. A human pratice humans were particularly found off during sex. Johnny never paid it too much mind before.

Until Prince Julius.

Kissing was then joined by hands. Hands cupping each other's faces, then maping out each other's bodies. They fucked until a silver line stretched over the horizon, clearing out the darkness of the Californian sky. Its light letting sliped nside the apartment complex where the two demons laid still, tails and limbs intertwined. 

The mark on Johnny’s shoulder itched. It felt like ages had passed until Johnny finally regained some of his sobriety. His head tilted to the side and he blinked when the light hit his eyes.

“Beautiful, isn’t it?” Julius wasn’t looking at his window.

Not yet trusting his ability of speech, Johnny simply nodded. He’d only heard of a sunrise before, but he never saw it since he always left his victims’ dreams way before morning came.

Johnny averted his gaze to the floorboards, engrossed in the way the light created thick beams where the particles of dust became visible to the eye. The light spread through the room and Johnny inched backwards on instinct.

Oh…

It felt… warm.

Julius laughed. “Nyohoho! You are seriously so freaking adorable, Johnny!”

Johnny ignored the prince’s remark. Instead he slumped against the other demon's side.

"I completed my punishment. What how?"

Julius brought one hand up to his hair. “You stay here to rest. ...Or maybe forever.”

Johnny hesitated. “Is that an order from my Prince?"

"It's a request."

He made a small noise of acknowledgment, purring as he's caught between the warmth of the sun and his new mate.

"Forever sounds nice..."
