Chapter Text
Kim Rok Soo woke up to a strangely wet sensation tickling across the back of his neck. He froze as he recognized the feeling of a body curved against his own, bare skin embracing bare skin causing his heart to skip a beat.
He opened his eyes and immediately recognized that this unscarred body wasn’t his own, pale skin clearly visible against soft white sheets. He’d have to turn his head to see the person who was most definitely kissing his neck right now, fingers splayed across his hips and causing a shocking ripple down his spine.
It was clear what had happened between this person and the body he was in. He could feel the stickiness between his thighs and an unfamiliar ache around his lower half. He may have never had sex in his original body, never having the inclination to try or a person he trusted well enough to attempt it with; But he wasn’t so ignorant to not know what was involved.
Stranger still though was the weird feeling of something wet seemingly coming from his own body. Not cum, but something simultaneously being produced and released from within. His chest was flat with no visible scarring, so he clearly hadn’t taken over the body of someone with a vagina. What exactly was this?
He reached a hand down, trying to be discreet, only to freeze once more as a decidedly male voice spoke into his ear.
“You want more already?” the hand on his hip reached to grab his own, before a knee came between his legs, separating them for easier access. “I can do it, Cale. Today is all about you, remember?”
Cale? Was that the name of this body then, is that who he had become? It was awfully familiar, and a bit concerning. If this was Cale, as in ‘ Cale Henituse ’, a minor antagonist from the fantasy-action harem novel he’d been reading the night before, he was in trouble.
After all, the novel itself had primarily been mindless smut with minor fantasy elements. What he'd been able to read before this...change had happened, had been primarily about the main character bedding as many partners as he could throughout the series while coping with his new biology and his quest for revenge..
It was almost a typical isekai plot. The main character, Choi Han, had been an average korean teenager before being placed in ‘The Forest of Darkness.’ There, he had faced insanely powerful monsters before finding a village and venturing onto his path to becoming a hero. What Choi Han hadn’t known, though, was that his body had changed upon arriving to this new world. Along with giving him the ability to understand the language, he had become an ‘alpha’, a type of gender in the fantasy world that had naturally higher strength, scent, and because it was a given with harem fantasies; –an absolutely insane sex drive.
To be honest, Kim Rok Soo hadn’t been at all interested in it at first as he didn’t care much for harem stories let alone smut. But it had been the only series in the library that had enough volumes to take up his vacation time, so he’d given it a chance.
The feeling of something long and hard entering his body broke him from his thoughts. He released a deep gasp as he was penetrated, his body instinctually submitting as his core was invaded. He hadn’t fully thought through his predicament and was now dealing with the fall out of his inaction.
Luckily, it didn’t hurt. Whatever activities they had done before he'd taken over had loosened this body's channel considerably. He found himself flushing red at the sound of something squelching as the man began to gently thrust inside of him, the echoing of slapping skin filling the air as he found himself being held against a firm chest.
Kim Rok Soo could barely focus on how – not right – it was to sleep with someone he didn’t know in a body that wasn’t his. It felt surprisingly good. He could barely stop himself from crying out, his head lolling back against a strong shoulder as the pace between them began to quicken, letting out accidental whimpers as his body began to move in tune with his unknown lover’s thrusts.
The man tilted his head to lay hot kisses down his neck, breathing heavily between each peck. Kim Rok Soo felt his world tilt from the overwhelming scent of it all. Whatever the novel had said about scents in this fantasy setting hadn’t scratched the surface of what they could actually do to a person. Kim Rok Soo felt as if he was drowning with pleasure, somehow able to differentiate between the scent of the body fluids and the overwhelming satisfaction and claiming exuding from the man’s pheromones.
His body was so hot, and he felt himself unable to stop himself from voicing just how good it was, arching into the hand that was now gripping around his straining penis and then everything went white and warm as he found himself coming–
He felt the widening of his lover, the grip of a knot that was unique to this world, catching on his rim. For some reason this weight inside of him only brought more waves of pleasure, the spurting cum making its home within him dragging out a second orgasm that he could barely voice with a soft, whimpering cry.
“Is the heat calming down now?” Cale’s lover questioned, softly caressing from his thigh to his stomach and settling there. “Do you feel cooler?”
A heat, something omegas went through every three months. He had only known what it entailed through the description Pendrick had given Choi Han when requesting the swordmaster’s assistance. The healer had spent nearly a week in the man’s arms and the both had come out stress free, only for Pendrick to die in the next battle which had resulted in both Lock’s beserk state and Choi Han’s fury.
From what Kim Rok Soo, or well, Cale, remembered: a heat was a time where omegas were in a higher state of sexual desire, and its name was no joke. Their pheromones would call out to alphas as their body temperature rose, and then said alphas would need to prove themselves worthy of an omega’s trust to be able to bed them, which in turn would return the body to its normal state, albeit temporarily. They didn’t lose their mind or their will during these heats as he knew sometimes happened in other stories, but the heightened desire mixed with the increased internal temperature did create a type of fever pitch pain within the omega. Which was why generally, in this universe, upon puberty most omegas were given some form of aid; whether it be in a heat partner or a protector who would wait within reach while the omega pleasured themselves.
If Cale had been in heat before he’d taken over this body then that meant that the person behind him must be none other than Eric Wheelsman; Cale’s heat partner at the beginning of the novel and his childhood friend.
Of course, Eric had ended his partnership with Cale the day before Choi Han had appeared, which prompted Cale to get roaringly drunk in response. It hadn’t been Eric’s fault that the partnership had to end, his parents had refused to allow him to further the relationship with the omega who’d gained such an awful reputation over the years.
Cale Henituse had been a difficult noble without many friends, but he'd been given many undue allowances because of his gender. Built far more gently than their alpha counterparts, omegas were rarities in this world and thus were treated as such. Jewels, gold, guaranteed advantageous marriages. Omegas had it all, and if they didn't upon their birth, they would be lifted from their low born stations and provided to properly.
Cale had been a strange exception among his gender, both drinking without a care among the townspeople and openly facing off against the alpha types who bothered him. He had no care for tact and no respect for nobility or their customs. When Choi Han, blinded by rage, had attacked Cale for insulting Harris village, the teenager had to flee Henituse County without receiving any help due to the risk of punishment after fighting the omega. He would be hunted for months until he was eventually pardoned by the prince.
Cale could be certain that this body hadn’t yet met Choi Han, as he didn’t have the scar he’d gain the night before it happened, let alone the other scars that would be left from the damage Choi Han had done.
Of course, there was one way to truly find out.
“Yes, I think I’ll manage.” Cale answered, gently easing himself out of Eric’s arms in hopes of creating some distance. His body ached in an unfamiliar way, his hole, one he wasn't sure was his asshole, or something else entirely, residually tingled, feeling empty. He grimaced as cum and fluid dripped out of his, his thighs and waist sticky with their mixed spend and sweat. Sex might have been better than expected, especially in this world with such different gender dynamics, but being covered in body fluids wasn’t exactly the best feeling in the world.
Plus, even if he hadn’t meant to, he still felt incredibly off put by the fact that he’d had sex with someone who didn’t know who he was.
“What day is it again?” Cale stretched as casually as he possibly could given that he was naked in front of a stranger who’d just made him see stars. Brown-red eyes avoided looking in Eric’s direction as he found a satin robe on the ground. He’d likely been using it before the heat had set in, robes being easier to take on and off.
“That good, huh?” Eric joked. “March 29th, year 781.”
Too late to help Choi Han and avoid the destruction of the village, then. What a shame.
“Ah, of course.” he pretended as if the day didn’t matter, even if it did. He’d have to restructure his plans. “I’m going to take a bath.”
“Do you want me to join?” Eric questioned, voice deepening, intent clear.
No longer able to avoid it, Cale turned to face the alpha.
He was…cute? His face looked as if it was meant to be in a library. Even with his messy light gray hair he had an air about him that screamed scholarly. Definitely the reliable type, just as the novel had described. Neither him or Cale had been in love with each other when they’d started the partnership, just as many other pairs weren’t. However they were good friends, and Cale knew that the original owner of this body had harbored some hopes that Eric would take him out of the county for good.
That of course, wouldn’t happen. Neither his father, Count Deruth, nor Eric’s father approved of a long term relationship. Count Deruth didn’t want Cale to leave the territory and give up any claim within his family, which he’d have to do if he was to become engaged to Eric.
It would be better to end this now, before he’d have to listen to the man’s drawn out, likely depressing, breakup speech.
“I think I’m very well sated, thank you.” Cale skillfully denied the offer. “I’m no longer in heat, and I know why you're sticking around when it’s not our usual way of doing things.”
Heat partners didn’t stick around for a cuddle and an extra fuck. Even if Cale hadn’t experienced a true heat yet he knew that he should feel hotter than this, more delirious with the lingering pheromones in the air.
He’d have to have the rooms aired.
“You…you do?” Eric questioned, eyes widening as he searched Cale’s face.
“I heard of your upcoming engagement last week. You were planning on ending it, correct?”
Cale had thought that had been the messiest part of the novel’s backstory for him, semi-neglectful parents aside.
“I…yes.” Eric admitted. “It’s the second daughter of the Chetter family, she isn’t willing to keep an open partnership so I can continue to service you.”
“And she was okay with you doing this?” Cale gestured to himself. “One last heat?”
Eric hesitated, looking slightly shamed.
“It took some convincing, but yes. She understands how important our relationship is, and how much you need me. I promised that this would be the last time.”
Cale crossed his arms at that, but figured it wasn’t worth discussing. Even in this world where multiple partners were relatively normal and even accepted in high society, there were plenty who still upheld the ideals of monogamy; especially when it came to upholding bloodlines.
He couldn’t personally say that he would have one last romp with a casual partner if he was engaged to someone who desired monogamy, but it wasn’t his place to get involved if the man had permission. Besides, it’s not as if he had been present for the start of all of this.
“Well, I’m fine now.” he explained, waving Eric away. “No more heat, so you're free to go.”
“Wait-” Eric sat up, the blanket shifting to reveal his lower half—wow he hadn’t expected an alpha’s cock to be that large. He'd nearly lost his train of thought at the size of it.
These damn fantasy harem novels. How unrealistic.
“Please don’t shut me out. This is the last time we can be together, Cale.”
Cale stood still as the alpha grabbed his shoulders, gently kneading the silk covered muscle with his thumbs while Eric gave him a small, nervous smile.
“I care about you, you know? We’ve been doing this together for nearly 4 years now.”
They had been heat partners since Cale was fourteen, from the very first time he’d presented. Cale had never known another alpha, a truly noble omega; whereas Eric, in contrast, had endless rut partners to choose from. If he remembered correctly, Cale had never actually event spent a rut with Eric. He had never been allowed to venture to the Wheelsman territory to assist him.
“I’m not shutting you out, hyung.” Cale used the title to create a bit of distance. He hadn’t called Eric ‘hyung’ since they’d started their partnership. “I’m just ready to accept that our partnership is over. You shouldn’t hold on like this.”
Cale moved the clinging hands from his shoulders as he gentle as he could before stepping back.
“I’m leaving for the bath now. If you could tell Ron to find me on your way out, that would be much appreciated.”
Ron, the assassin currently masquerading as a butler, would surely already be brewing his birth control tea. It was bitter stuff and Cale hated drinking it, but it would prevent any chance of pregnancy and suppress his scent for the next few hours.
Thanks to fantasy-harem standards condoms weren’t a necessity here. STDs didn’t exist thanks to everyone possessing some small form of mana—bullshit harem excuses—and magic herbs that had a 100% effectiveness rate at controlling pregnancies if taken in the right period of time—even more bullshit harem excuses, but one he was glad existed a this exact moment. Considering there were currently two empty glasses sitting on the table next to his bed, he assumed previous Cale had done his due diligence by taking it at the appropriate times.
Cale didn’t care how different this world was, he wasn’t exactly a fan of the idea of birthing a child. He wasn’t parent material and even if he was, the process wasn’t ideal.
“I see…sure, dongsaeng.” Eric finally replied. “I’ll return to my rooms and prepare to leave, then.”
“Thanks for everything.” Cale said sincerely.
His first experience with sex had been rather nice thanks to the other boy, and he wasn’t going to pretend he didn’t enjoy it or pretend to be bitter just to stay in character. Besides, Eric had been a longtime supporter of the original Cale Henituse, even if he had slightly broken his heart in the end.
“One last thing, before I leave?” Eric grabbed his hand gently, his other hand reaching for Cale’s face. Cale didn’t move as a thumb caressed his cheekbone, gray eyes searching his own. “Can I kiss you?”
How sappy. No wonder Cale had gotten so wasted; this man was sending so many mixed signals.
Still, Cale held none of the lingering affection that his predecessor had, so he agreed to it. A final thanks for the person who’d taken his ‘virginity’.
Eric’s lips crossed over his softly, head tilted to the right as the hand that had been caressing his cheekbones moved to grip his chin. It had started relatively chaste, but before Cale knew it the older man had slipped his tongue in between his lips, causing a small shiver down his spine at the taste he was given.
Eric definitely knew what this body preferred.
Cale pulled back, a string of saliva embarrassingly following him. He quickly wiped at face before patting Eric’s shoulder, ignoring his downtrodden expression at the distance. This was enough.
“I’ll see you around, Eric.”
Not wanting to risk seeing what he’d do if he waited for a response, Cale quickly made his way over to the bathroom door and closed it behind him, locking it for good measure.
Alphas were dangerous.
He quickly stripped off the robe and decided to take a look at the large mirror in the center of the room. The person facing back at him was definitely who had been described in the novel.
Red hair, a delicate but handsome face. A slightly muscular but still lithe figure, with pale, soft skin. His neck and chest was littered with bite marks, and there were handprints on his hips, a sign of an omega well-fucked. Even now he could see milky cum dripping down his thigh, and dreaded having to clear out what had been described in the novel as an alpha’s load. Exaggerated alpha traits equaled an unnecessary amount of cum, unfortunately. Might as well starting cleaning it up now.
But still, he thought as he reached down to do just that.; Sex hadn’t been so bad. He wouldn’t mind trying it again with someone else. Especially with how low risk it was in this world. He’d have to think more about it later. For now, he just wanted to get clean.
He'd work on protecting himself from Choi Han afterwards.
