Chapter Text

Rumi had never felt so free in her life, never before had she been able to be who she was, to be seen for all she was, and the feeling was so incredibly liberating for the purple-haired popstar. 

 

But she wasn’t the only one benefitting from her newly freed status, her two co-idols and girlfriends Zoey and Mira absolutely adored the recent changes in their leader.

 

She walked with a confidence and ease she never had before, it was no longer a forced, manicured appearance put on for the cameras, it was just her, it was so Rumi

 

Which is why the two girls now sat confused, worried, and scared for their girlfriend who had suddenly ripped herself from the couch and barricaded herself in her room like the cops were coming for her,

 

“Rumi, what happened?” Zoey asked through the door, lightly tapping her knuckles against the polished wood, “If you farted you don’t have to run off like that, it’s usually me who does that anyway!”


“Zoey!” Mira scolded lightly, but a smile grew across her face as she saw the cheeky little grin across Zoey’s before the pink-haired girl turned to the door, “But seriously Rums, what’s up?” 

 

“Nothing…! Just-” Rumi began, but immediately cut herself off, “I uhm- I felt something and panicked when I saw it and-” 

 

“It?” the two girls said in unison through the door, 

 

“You can show us, Ruru, c’mon…” Zoey’s soft voice came through the door as she practically squished herself against the wood, “You know we would never ever judge you!”

 

“Not ever,” Mira said with a resolute nod, before realizing Rumi in fact could not see her, “Please open the door, Rumi.” 

 

After a moment of silence the lock clicked and the door opened,

 

“GOTCHU!” Zoey yelled as she practically dove at the half-demon, tackling her across the room onto the bed with a demanding huff, “You do not get to run away from girlfriend cuddles like that, I still had-” she paused, thinking for a second,

 

“Fourteen,” Mira filled in for her,

 

“Fourteen more turtle fact clips to show you! And I made sure to pick out the really good ones!” Zoey huffed as Rumi laughed brightly, the sound almost washing away all of the two girl’s worries in a moment.

 

Almost.

 

But the two girls spied two things up with Rumi, one, she was wearing one of Zoey’s bucket hats, and the two girls each caught a glimpse of her small, pearlescent fangs poking out.

 

Normally, Rumi’s fangs only ever showed when she was having a particularly bad emotional spiral, yet she lacked the characteristic deep purple marks, or yellow eye that came along with it. Besides that, it only ever showed up when she was getting particularly… intense in bed; which was most certainly not what was happening here.

 

“What’s with the hat, Ruru?” Zoey asked, going to pluck it off her head, “You never wear hats cause it messes up your-” Rumi protectively yanked the hat down to the point it was nearly covering her ears, “Hair…” 

 

Mira and Zoey exchanged a quick look with one another before turning back to the half-demon who averted their gaze nervously, her patterns flashing a series of moody blues and pinks,

 

“Rums…” Mira cooed as she sat down beside her, gently pulling her hands off the hat, Zoey taking her left while Mira took her right, “Can you let us look, please?” Mira’s soft brown eyes met Rumi’s, the leader biting her lip before nodding her head nervously, “Thank you, baby.”

 

Mira gently pulled the bucket hat off Rumi, her breath hitching as what she was trying to hide was revealed clear as day.

 

A pair of tiny, barely visible horns poking out of Rumi’s scalp, their tips tinged slightly purple, yet still so small one could easily mistake them for a particularly nasty bump,

 

“My forehead had been itching like crazy lately and-”


“Oh thank god I thought you had lice,” Zoey blurted out, letting out a loud sigh of relief that Mira quickly swatted her for, “You were thinking it too!”


“Unimportant,” Mira scoffed before turning their attention back to their girlfriend who attempted to shift away, but unfortunately for Rumi, her girlfriends had no intention of letting that happen, “Keep talking, yaobo.”

 

“We were just cuddling and I went to rub my forehead and-” Rumi traced her finger along the bottom of one of the small horns, “What are we going to do…” she muttered to herself, pulling her knees up to her chest as her two girlfriends wasted no time,

 

“I’ll tell you what we’re going to do,” Zoey said with an amount of certainty that even startled Mira, “We’re going to order a mountain of takeout, bundle up back on the couch, get comfy, and figure it out tomorrow, okay?” Zoey leaned up and planted two small kisses, one for each of her baby horns, “I think your baby horns are adorable, and if we managed to get the press to not ask questions about your new ‘full body tattoos,’ then I think we can get away with a little more wordsmithing.” 

 

Zoey’s confidence, mixed with her undeniable dorkiness and charm made Rumi’s moon lift in an instant, a smile tugging at the corners of her lips as she nodded,

 

“I really like the sound of that…” she murmured as Mira wrapped her arms around Rumi and lifted her into a bridal carry,

 

“In that case, I think our nepobaby could use a shower, Zoey, you get the order together and-”

 

“You’re going to shower without me???” Zoey blurted out, pouting at Mira like a kid who got told they aren’t going to Disneyland, “I would rather starve!” 

 

No,” Mira said with a little laugh, walking over and planting a soft kiss on Zoey’s lips, “You, can join us after you’ve ordered the food, I know with that kind of motivation you won’t have too much decision paralysis.”


“I’ve already decided to buy one of everything and deal with the consequences,” Zoey said in the most direct, no-nonsense tone as she immediately pulled her phone out and tapped through doordash like her life depended on it,

 

“Ready, tiger?” Mira asked with a laugh as she carried Rumi into her en-suite bathroom, stepping onto the cool tile as she set the half-demon down on the counter,

 

“And when did this exactly become, ‘spoil Rumi,’ time? Last I checked…” Rumi mimed looking at her watch, “It’s Tuesday and it's my turn to cook dinner.”

 

Mira slapped her wrist lightly and cocked her eyebrow, “So we’re not allowed to love you?” she asked poignantly, satisfied with how Rumi’s jaw closed with an audible click and her stubborn expression melted into a small pout, “Good.” 

 

Mira grabbed the hem of Rumi’s t-shirt and pulled up, the half-demon having long since outgrown the engrained fear of Mira doing exactly that to her, instead basking in the intimacy of the moment as the shirt fluttered to the tiled floor below. A small grin spread across Mira’s face as she moved just an inch closer, her hands settling on the small of Rumi’s back,

 

“Mira…!” Rumi squeaked, her patterns flushing a telltale shade of bright pink, 

 

“Something wrong, gongjunim?” Mira teased, knowing full well the effect she was having on the girl as she turned an even deeper shade of pink, “I’m just-” Mira titled her head up to look at Rumi but instead stopped dead, her eyes locked onto Rumi’s forehead,

 

“What is something…” Rumi looked up and gasped loudly, scrambling backwards on the marble counter, “THEY GOT BIGGER??” 

 

Rumi was slack jawed as she stared at her reflection in the mirror, the horns that just moments again were no more some slightly pointy mounds were now a couple centimeters in length. The horns were a shade of pink for just a moment before flushing purple just as Rumi’s marks did,

 

“Oh my god, oh my god, oh my-” Rumi stared at herself in the mirror, eyes wide as she laughed hysterically,

 

“Rumi!” Mira yelled, pulling her girlfriend back and placing her hands firmly on her shoulders, “Rumi, deep breaths, one, two, three in- one, two, three out-”


“Mira!” Rumi gawked back, her voice somewhere between tears and laughter, “I have horns- oh god… what next… oh my god…”

 

“Rums… Rums… hey…” Mira soothed as she pulled Rumi into a hug, the topless girl burying her face into the crook of Mira’s neck who winced as one of the horns poked at the underside of her chin, “Ow-”

 

Rumi recoiled back at the sound, looking at Mira like a cornered animal as her mouth hung open,

 

“Rumi, hey, I’m okay, it was an accident you don’t need to-” Mira began but Rumi was already spiralling, her patterns twisting into deep, near black shades of purple as the horns atop her head seemed to grow just a bit more, “Wait, Rumi, hey, wait-” but Rumi wasn’t listening, she needed to do something fast to get the girls attention.

 

And then it hit her.

 

Mira pulled her shirt off over her head, exposing her torso completely to Rumi and grabbed both of Rumi’s hands and placed them onto her chest. The sudden motion snapped Rumi out of it like she had ice water dumped on her head before her face flushed pink,

 

“MIRA!” Rumi squeaked, her marks, and horns, turning that tell-tale shade of rose, “This is not- it’s not-”


“Listen,” Mira commanded, moving closer as she guided Rumi’s gaze around the mirror towards the two horns, “I saw them get bigger for a moment, but now they’re back down a bit…” she gently cupped Rumi’s face, “Ru, you know how when you get super emotional your marks get more intense?” The half-demon nodded, not once breaking eye contact with her girlfriend, “This may be like that, so hey, for me, lets try to stay calm while we figure this out, can you do that for me?”

 

“I-” Rumi began, before nodding, “I can, Mira,” she said with a small smile that made Mira’s chest flutter,

 

“Good girl, now let’s get your pants off and get you in the shower,” Mira grinned as she yanked Rumi’s sweatpants off, the girl squeaking loudly as Zoey rounded the corner already naked,

 

“And I’m-” she groaned, “Oh c’mon if I knew we were doing this I would’ve let you two strip me!” she huffed, sticking her tongue out as she leaned against Mira before her eyes went wide, “Ruru… not to alarm you but-”


“The horns got bigger,” Rumi and Mira finished for her as Zoey sighed,

 

“Oh thank god, I didn’t want to be the one to bring it up and-” a look of confusion crossed her face, “Wait, how?” 

 

“My guess is that when our little firefly here gets really emotional they act up,” Mira explained as she traced her fingers along the patterns on Rumi’s stomach, adoring the way she squirmed at the light touches, “Like her patterns, happened when I took her shirt off and when she had a little panic attack.” 

 

“Ohhh,” Zoey snapped her fingers, “Rumi you had a horner!” Zoey grinned at the two like she was the most clever person in the world, but the at best bemused expressions of her girlfriends certainly did not agree, “Oh come on that was funny!”

 

“No it was terrible,” Mira groaned, rolling her eyes, 

 

“And we are not calling it that,” Rumi added as Zoey just put her hands up in mock surrender,

 

“Fine, fine! But next time you need lyrics come up with it yourself if I’m soooo bad at words thennn,” Zoey said with a played up tone before the three girls devolved into laughter, Zoey yanking Mira’s sweats off before the three girls fumbled into the shower in a tangle of limbs, basking in the warmth of hot water after a long day.

 

A sensation doubled, maybe even tripled with the addition of one’s beloved girlfriends.

 


 

After a nice, chill night Rumi’s horns had completely subsided, vanishing from her forehead as if they were never there in the first place. Rumi sighed a breath of relief, hoping it was just some weird fluke, but deep down she knew it wasn’t that.

 

A couple weeks had gone by, and despite the three each keeping an eye out for a wayward horn, especially when in public, nothing had shown up.

 

Strange.

 

The three now sat around the dining room table, passing around plates of galbi, bulgogi, rice, kimchi, and whatever else the three had cooked up for dinner.

 

Laughter and casual conversation filled the air, talking about how practice was today, their schedules for the upcoming week, their plans for a new single, when Rumi abruptly dropped out of the conversation.

 

Which wasn’t unheard of, Rumi was prone to bouts of silence preceded and followed by loudly joining in on their nonsense. But when the two girls glanced over at Rumi, they weren’t met with her watching the two with a smitten expression, but instead the half-demon shoving chunks of bulgogi into her mouth like a starving hyena. 

 

The hyena thought wasn’t far off either, seeing as Rumi’s teeth had honed into sharp points, tearing into the tender, marinated flesh of the beef before swallowing it, only for it to be followed by another mouthful. 

 

Mira and Zoey watched the sight with a mix of amazement and worry over how she could eat that much that quickly and well… how she could eat that much that quickly. 

 

“Rums?” Zoey asked, laughing but Rumi didn’t respond, instead shoveling another giant chunk of steak into her mouth, before dropping all pretenses and dropping the chopsticks, residing to just lift the bowl to her head and eat directly from it, “Mira!”


“What!?” The pink haired idol whisper-shouted back at her girlfriend,

 

“Do something!” 

 

Mira just threw her hands up before resolving to snatch the bowl of beef from Rumi, “Hey tiger, wanna slow down there a bit?” Mira said, trying her hardest to sound casual as Rumi blinked at them like she didn’t even know they were there, “I know you like when I use the grill outside but save some for us, Ruru.” 

 

“What?” Rumi asked, bits of steak falling out of her mouth onto the plate beneath her as she looked at the now empty bowl of bulgogi and back at Mira, “Oh my god, I’m- sorry I-”

 

“Rummiiiii,” Zoey said in a sing-songy tone, cuddling up to her girlfriend’s side, “It’s okay, we just didn’t want you choking,” she smiled lightly, wiping Rumi’s lips with her thumb, “And you’re looking a bit… pointy.”

 

“Pointy?” Rumi tilted her head before raising a hand to her mouth, pressing the pad of her thumb down on her now sharp teeth, “Oh my god…!” She gasped, clasping her hands over her mouth as her patterns flushed red, “I was just really hungry and the meat smelled so good and-” 

 

“Ruru,” Mira smiled at her girlfriend, pulling her hands down from her face, “It’s okay, if you’re hungry, then eat, listen to your body.”

 

Rumi was about to open her mouth in protest, but a quick look from Zoey and Mira pulled whatever she was going to say right from her throat, 

 

“I just… What is going on with me?” she muttered, fiddling with the sharp teeth in her mouth, “First the horns now this…”

 

Zoey hummed thoughtfully through a mouthful of rice before snapping, “Puberty!” 

 

Mira and Rumi each cocked an eyebrow at the black-haired girl who nodded resolutely,

 

“Rumi’s having demon puberty!” She clarified, swallowing the mouthful of rice, “I mean it makes sense… ever since she went all demon-y after the idol awards and stuff… could be her body getting used to it and getting more… well honestly I don’t know but-”


“No I think you’re onto something, Zo,” Mira replied with a small nod, looking at Rumi who looked somewhere between uncomfortable and confused, “You have been eating a lot more, then the horn changes, now this… I think Zoey could be right, Rums.”

 

“But why now??” Rumi sighed, her head dropping into her hands as she grumbled, “Our comeback is in like… a month! We don’t have time for this, we don’t-”


“Rumi.” 

 

The strength in Mira’s voice snapped their leader out of the spiral she was teetering into,

 

“We have all the time for it, I love our fans, we all do, but you are more important than our comeback,” Mira said poignantly, her strong, brown eyes boring into Rumi’s, “We will delay it as long as we need until we figure out what’s going on with you and find a way to make you feel good, okay?”

 

“Yeah!” Zoey added with a chipper smile, “Besides, I think it's hot!” 

 

Rumi’s face flushed bright pink as she let out a barely audible squeak, clasping her hands over her eyes when the light laughter from Zoey and Mira abruptly stopped,

 

“Uh, Ruru?” Zoey murmured, scooting a bit closer as she pulled Rumi’s hands down from her face, “Your claws are back.” 

 

“AGH!” Rumi yelped, looking down at her hands, her right hand a foggy shade of purple that ended in five, sharp claws, “God damnit!”

 

Mira got up from her seat across the table and wrapped her arms around Rumi, motioning Zoey to do the same who happily obliged,

 

“You’re okay… it’s going to be okay,” Zoey soothed, rubbing small circles into Rumi’s back as the half-demon shuddered, “You know we love your demon-ness Ruru… it’s a part of you.”

 

“And whatever is going on, we can get through it together, okay?” Mira added, tilting Rumi to face her, “We got you, tiger, always.” 

 

Tears prickled at the corners of Rumi’s eyes as she looked up at Mira, her lip trembling as she tried to grasp onto words,

 

“Shhh…” Zoey soothed, pressing a small kiss to the corner of Rumi’s mouth, “If anything mean about yourself comes out of your pretty lips I will be so mad,” Zoey said with a cute pout, successfully shattering the tension in the room as Rumi smiled,

 

“It’s not fair how cute you are,” Rumi muttered as she tucked her face into Zoey’s neck and planted a couple small kisses on her skin, “But… thank you, you two…” Rumi sniffed at the air a couple times, her nose crinkling as she looked over to the door, “Bobby?”

 

The two other girls gave Rumi a confused look just as the elevator dinged,

 

“Giiiirls!” 

 

Bobby’s voice filled the room as the sound of his sneakers hitting the wood floor approached,

 

“So I know it’s late, buuuut I wanted to come by because I was out at the store and I saw some stuff and was like this is so you guys and-” Bobby rounded the corner into the kitchen to see Mira and Zoey suffocating Rumi in a hug who was looking decidedly more demon than normal, “Did I… oh my god am I interrupting something, I am so sorry and-” 

 

“Bobby it’s fine,” Rumi laughed lightly, disentangling herself from her two girlfriends, “Though it is good you’re here, we probably should talk about…” Rumi gestured to herself, “This.”

 

Bobby blinked a couple times before nodding, “Okay! I will go sit down on my chair and I will let you guys finish eating, sorry again!”

 

“Bobby it’s fineeee,” Mira drawled on as their manager trotted out of the room, Zoey and Mira turning back to Rumi, “So uh… how did you know he was coming?”

 

“I smelled him?” Rumi answered like it was the most obvious thing in the world, cocking her head curiously, “He has a pretty distinct smell and-”

 

“Rums he was in the elevator, Mira and I certainly didn’t smell him,” Zoey added, pursing her lips a bit as Rumi seemed genuinely confused,

 

“Really? Because I… I dunno, I can smell when you guys are coming, and when you were last somewhere, like when I wake up and you’re not in bed I can-” 

 

“Let me stop you there,” Mira put her hand up, cutting off Rumi in a moment, “How long have you been able to smell us coming?”

 

“A couple of-” Rumi began before groaning loudly, “God damnit!” Zoey and Mira started laughing, only making Rumi more frustrated, “Oh come on!”


“It’s a little funny,” Zoey offered, smiling cheekily at her girlfriend, “Our Rumiii is going through demon pubertyyyyy.”


“I am not!” She huffed, but Mira just smirked,

 

“You sure?” She teased, hooking Rumi’s mouth open and running the pad of her thumb along the pointy teeth, “Got a lot of evidence to say otherwise.”


“I hate you,” Rumi huffed, pushing Mira’s thumb out of her mouth before turning to walk towards the living room, “You’re both so mean to me!” 

 

“We love yooooou,” Zoey threw her arms around Rumi from behind, following behind her as she walked away, “We love our cute little demon, I think the pointy teeth are cute, and imagine what they would feel like-”


“BOBBY IS HERE!” Rumi scowled at Zoey who just giggled innocently, planting a small kiss onto Rumi’s cheek before skipping past her towards the couch as Mira followed, passing her a bowl filled with rice and the leftover galbi,

 

“Still hungry?” Mira asked, already knowing the answer by the way Rumi’s nose twitched at the smell of meat and the subconscious grumble she let out,

 

“I already ate so much and-” Rumi began but Mira just shushed her with a single finger pressed to her lips,

 

“Be a good girl and eat until your body says you’re full, okay? That’s how you tell when you’re done,” Mira said as Rumi just nodded, taking the bowl from Mira as the two girls joined Zoey on the couch opposite from Bobby.

 

“Sooo, what did you get for us?” Zoey asked, wiggling her way between Rumi and Mira, “Was it sweets? Oh please tell me it was, we’re out of ice cream and I think I’m gonna-”


“No, but I did bring some lotte choco pies because-”


“I love those!” Mira blurted out, Bobby smiling as he tossed the box to Mira who caught it with one hand, “Erm-” she cleared her throat, “Thanks, Bobby.”

 

“Always!” he smiled before reaching back into his bag and placing three, small vinyl figurines on the table, “I saw these in a gacha machine and had to get them,” Each was a small animal figurine: a blue hyena, a pink giraffe, and a purple tiger, “They reminded me of you girls!” 

 

“Awww, Bobby!” Zoey coed as she scooped up the small hyena, holding it up next to her face, as Mira picked up the giraffe, “I see the resemblance, Mirs,” Zoey giggled, Mira rolling her eyes,

 

“And you laugh like a hyena,” she replied while sticking her tongue out at Zoey who beamed with pride,

 

“And your patterns look a lot like tiger stripes, Rumi,” Bobby explained as Rumi looked at the tiny figurine fondly,

 

“Thank you, Bobby,” Rumi smiled softly, “Though… how long did you spend trying to get all of them?”

 

Bobby’s face suddenly went pale, “Uhm- I actually got really lucky and only-” 

 

But unfortunately for Bobby, just as he tried to defend himself, he accidentally tipped over his bag, unleashing a torrent of gacha capsules onto the living room floor,

 

“Bobby!” The three girls groaned in unison as he smiled sheepishly at them,

 

“I got the tiger and giraffe quickly but I couldn’t get the hyena!” He said trying to defend himself, but the three girls were each giving him a look as he desperately tried to shovel the capsules back into his bag, “You said you wanted to talk about something?” He added quickly, hoping to throw the three girls off of him,

 

“Oh yeah,” Mira leaned back, looking over at Rumi who was staring intently at the tiny tiger toy in her hands, “Rumi’s going through…”


“Demon puberty!” Zoey said with a nod,

 

“Demon puberty,” Mira repeated before turning back to Bobby, “And she’s getting antsy about our upcoming comeback, could we possibly push it back a bit while we figure out what’s going on here?” 

 

Bobby looked over at Rumi who shifted awkwardly under the attention, holding her arm with her clawed hand as she looked down to the side,

 

“I mean yeah!” Bobby answered with a smile, “You girls are the most important thing, the comeback can wait if you guys aren’t feeling up to it!” he smiled, “I’ll figure out everything for it, you three just focus on that, okay?”

 

“Thanks Bobby,” Mira said with a smile as Bobby just gave the three girls a big cartoony thumbs up,

 

Actually, as your manager I am ordering that Rumi is not allowed to even think about the comeback until she’s feeling better.”


“Bobby!” Rumi protested, but between Bobby and her two girlfriends Rumi knew she had no chance at winning, “We’ve been working on this for ages!”

 

“And the fans love you enough that they can wait a little more,” Bobby remarked as he stood up, “Now I’ll go and work on pushing the stuff back a bit, oh and do you want me to start working on any explanations behind the teeth and ears?” 

 

“Ears?” The three girls said, Mira and Zoey turning to Rumi who froze,

 

“Awww! Ruru! You have elf ears!” Zoey cooed as she leaned over and tugged on them, “They’re so pointy and purple!”


“Zoey!” Rumi squeaked as Mira leaned over, “Oh my god another thing to-”


“These are cute,” Mira grinned, tugging on one of them and smirking at the cute face Rumi made, “Oh I wonder if-”

 

“BYE GIRLS!” Bobby yelled as he made a very quick escape from the room, wiggling across the penthouse to the elevator as fast as his 4’7” self could.

 

The three girls burst out laughing as they watched Bobby dip, giggling and trading small looks with one another before settling back down,

 

“How did none of us notice?” Rumi asked, pouting a bit as Mira and Zoey played with her ears, trying to suppress the shiver that traveled down her spine,

 

“We were busy talking to Bobby, baby,” Mira soothed, pressing a small kiss to the shell of Rumi’s ear, “Besides, I bet they’ll go back to normal in the morning, seems these are all temperamental at worst.”

 

“Yeah! And besides, ears and teeth are easy enough to convince fans they’re just props or makeup!” Zoey smiled, her earnest, genuine giggle melting the worry away from Rumi’s expression, “Besides-” Zoey took a bite of a choco cake, “You look hot like this!” 

 

Rumi’s face turned bright red again as her marks flushed pink, “Zoey!” She squeaked, trying to bat her maknae away but Zoey just pressed further,

 

“You’ll look sooo hot all demon-y babe, with your horns and ears and-”

 

Rumi did the only thing she could possibly think of to silence her girlfriend and rammed her lips against Zoey’s. The younger idol squeaked in surprise as Rumi tackled her across Mira’s lap, kissing her silly as Zoey let out muffled squeaks from underneath Rumi,

 

“Rumi!” Zoey tried to protest as the half-demon peppered her in kisses before she was abruptly pulled away by Mira yanking on her braid, “Hey!” Rumi protested, but Mira just smirked down at her,

 

“While it is hot seeing you make out on my lap, I don’t like being left out,” Mira rolled her bottom lip in her mouth before pulling Rumi’s top off, “Besides…” 

 

Mira leaned down and dragged her tongue up the length of Rumi’s neck, purring at the gorgeous shade of pink she turned,

 

“Zo and I wanna test something…”

 

Zoey smirked as she pushed her hands up under Rumi’s shirt, pulling the loose fabric off and whistling at the sight,

 

“Mmm… god you’re gorgeous, Rumi,” Zoey murmured as she pressed a light kiss and bite to Rumi’s collarbone as Mira smirked down at the two of them, “Oh…?” 

 

Zoey smirked a bit as she felt something, rolling her hips up into Rumi who let out a soft mewl, her face turning red as the half-demon began absentmindedly grinding herself down onto Zoey,

 

“So eager…” Mira crooned into one of Rumi’s ears, the half-demon letting out a soft whine as she gripped Zoey’s hips and continued grinding herself against her, her tongue lulling out of her mouth, “Come on Rumi, let’s get those clothes off of you…” 

 

Rumi whined impatiently as Mira pulled her off Zoey, the black haired girl wasting no time in pulling her own clothes off as Mira got on her knees and pulled Rumi’s sweatpants down, whistling at the bulge forming in Rumi’s cute, purple panties,

 

“Awww, Ruruuuu, you get worked up so quickly,” Zoey teased as she moved over to Rumi, wrapping her arms around the half-demons waste from behind, trailing a finger up one of the patterns on her belly, “Isn’t that right, Mira?”


Mira rested her face against Rumi’s thigh as she looked up at the purple-haired girl whose face was flushed right, a small whimper escaping her lips as Mira smirked,

 

“She is awfully needy…” Mira hummed, looping a finger loosely into the hem of Rumi’s panties, “What do you want, Ruru, use your big girl words.”

 

“Please,” she gasped out, a soft whine falling from her lips as she tried to press herself into both Zoey and Mira’s grasp at the same time, “I need to be… to be-”

 

Zoey smirked, dipping one hand lower and past the elastic of Rumi’s panties and stroked two fingers along her hardening length, eliciting a full body reaction and moan from the half-demon,

 

“Need to be what, unnie?” Zoey cooed into Rumi’s ear as her girlfriend let out a pathetic whimper,

 

“Please let me fuck you Zoey, please,” Rumi begged, leaning back into her macknae as she whined, “Please I want to fuck you while Mira touches me please, please-” 

 

“Good girl,” Zoey smirked, biting down on the shell of Rumi’s ear, forcing a sharp cry from the half demon as Mira yanked Rumi’s panties down without another warning, “What do you think, Mira?”

 

Mira grinned wolfishly as she wrapped Rumi’s legs around her waist and lifted her up,

 

“I think I’m gonna hammer her cute ass into the bed while she fucks you, baby,” Mira grinned as Rumi rolled her hips against Mira’s belly with a needy whimper as she was carried through the penthouse and tossed down onto the bed,

 

Please,” Rumi pleaded as she looked up at her two girlfriends, crawling towards them on her hands and knees, “Please, you smell so good, I-”

 

Mira stripped in one, smooth motion as she sat down on the bed besides Rumi, cupping the half-demon’s face as she purred soothingly,

 

“What do we smell like, baby?” She asked with a small smile tugging at her lips as Zoey fetched the strap, “Tell us…”

 

“S-sandalwood and cinnamon…” Rumi gasped out as she looked up into Mira’s eyes who smirked as she watched that telltale yellow begin to form in Rumi’s left eye, “Zoey like… like…” Rumi whimpered loudly, “Please touch me, please please-”


“I am touching you, Rumi,” Mira chuckled darkly, tracing one hand down Rumi’s side who squirmed, “Now tell me what Zoey smells like, baby…”

 

“S-sweet…!” Rumi gasped out, whining as she tried to press herself against Mira but instead just ground herself against the bed, “Like sea salt and caramel she-” Rumi let out a gasped moan as Mira obliged the writhing demon and offered up her thigh to Rumi who rolled her hips against Mira like it was all she knew how to do,

 

“Good girl…” Zoey cooed as she set the strap down beside Mira and moved behind Rumi, her hands ghosting up her girlfriend’s stomach before kneading her chest, “Like how we smell, don’t you?” Rumi nodded wordlessly as she ground herself against Mira’s thigh like an animal,

 

“God you’re pathetic…” Mira muttered as Rumi whined, “You’re going to cum just from doing this, aren’t you?”

 

“No… no!” Rumi squeaked out, looking up at Mira with a needy expression but not stopping her grinding even for a moment, 

 

“Really?” Mira raised her eyebrow, smirking at how Rumi writhed so beautifully under her, “Then why don’t you do what you begged so nicely for and take Zoey…” 

 

Rumi whined loudly up at Mira but still didn’t stop, looking over at Zoey who played with her chest, “B-but-”

 

“But what, baby?” Zoey moaned into Rumi’s ear, the demon’s body shuddering as her jaw shifted, a pair of large, tusk-like teeth pushing past her lips, “If you don’t take me now then maybe I’ll have Mira do it and show you how it’s done…” 

 

At that something snapped in Rumi as she tore herself off Mira’s thigh and tackled Zoey onto the bed, her eyes glowing yellow in the dim light of the bedroom as she panted down at Zoey, 

 

Mine.

 

Rumi snarled down at Zoey as she got down on her knees in front of her, yanking her maknae’s hips around her waist as she lined herself up and pushed in letting out a mind numbing moan of pleasure,

 

“Fuck!” Zoey gasped as Rumi growled down at her, the deep sound radiating from Rumi throughout Zoey’s body as the girl gripped the sheets, “Fuck you feel big…!” 

 

Rumi wasted no time in hammering into her girlfriend, flecks of drool roping down onto Zoey’s bare stomach as the half-demon railed into her, the wet, lewd sounds of Zoey only egging her on more and more,

 

“Aww…” Mira crooned as she moved up behind Rumi, pressing her back flush to the half-demon as she raised her hands to Rumi’s ample chest, “Doing so good for us baby…” she ghosted her lips along Rumi’s ear, purring at the way she shivered at the light touches.

 

Rumi let out a whine before staggering out a moan as she lifted Zoey’s hips up to slam down harder and harder into her girlfriend as her eyes burden bright yellow,

 

“More… more…” Rumi growled as she kept hammering into Zoey, the black-haired girl squealing  as Rumi abruptly lifted her, spun her around, and mounted her into the bed, “Breed…!” 

 

As Rumi howled out in desire something curious began to happen, the half-demons face began to shift. Her nose and jaw pushed outwards, her face elongating into a snout as her tusk-like fangs grow into large, oversized canines as she let out a guttural cry of need,

 

“R-Rumi…! Too much- I-I-” Zoey pleaded between moans under Rumi,

 

“Mine.”

 

Her voice was deep, rough, and coated with a deep burning need as she railed into Zoey, her jaw tight as her brain screamed to bite her.

 

Rumi’s jaw flexed as she bent down, her large teeth poised over the tight cord of Zoey’s shoulder when she was suddenly yanked by her braid,

 

“No biting, baby…” Mira hummed, hooking two fingers into Rumi’s mouth and humming approvingly, “Awww… is our little demon teething? Needs to bite?”


Rumi whimpered and whined pathetically as Mira manhandled her, squirming hopelessly in her hands as she kept up her messy thrusts down into Zoey,

 

“L-Let her…” Zoey panted out from against the mattress, her and Rumi’s juices pooling on the once pristine sheets as Mira chuckled darkly,

 

“I don’t think so…” Mira chuckled as she kept Rumi held in place, looking into those feral, need fogged eyes of her girlfriend, “I think our little demon is a little too far gone here… isn’t that right, Ru?”

 

Rumi let out a pathetic whimper as she squirmed, trying to pull herself free of Rumi’s arms to no avail, a long, strong tongue shooting out and wrapping around Mira’s fingers,

 

“That’s what I thought…” Mira leaned in closer to one of Rumi’s pointed ears, “Now be a good girl and breed her…” she smirked and pushed Rumi down flush onto Zoey’s back, the demon gasping loudly as Mira wasted no time in pushing a strap into her tight ass, “Fuck… good girl.” 

 

Rumi whimpered loudly, drool trickling out from her shiny, ivory teeth as she tried hard to thrust into Zoey, but the weight of Mira pushing her down kept her pinned,

 

“Oh poor thing…” Zoey teased as she rolled back over, cupping Rumi’s face as the half demon whimpered pathetically, “Can’t do it, can you? Can’t breed me.”

 

Rumi whimpered hard as she tried to buck hard into Zoey, but a firm thrust from Mira sent Rumi trembling back into nothingness,

 

“Guess I’m gonna have to fuck you into Zoey, Ru… seeing as you can’t finish her off yourself,” Mira smiled wickedly as she gripped Rumi’s hips, biting her lip at the way her patterns flashed in response as she set into a hard and deep rhythm, the pink strap bottoming out in Rumi’s tight ass with every single thrust.

 

Rumi howled in need as Zoey panted in unison with her, the force of Mira’s hard, strong thrusts combining with the messy, needy ones of Rumi in such a way that neither of the two girls could take it. 

 

Rumi broke first, completely lost to the demonic lust consuming her as she howled loudly through her orgasm, Mira holding her braid like a leash to keep her from biting Zoey,

 

“Fuck baby… good girl… cumming in Zoey so good, want to breed her? Fill her with your demon pups?” Mira teased, grinning at how red Rumi was and how fucking beautiful she looked. 

 

Two gorgeous, curved horns sat atop her head, a deep shade of uniquely Rumi purple. Her marks shone with need, want, desire and love, her skin a veritable stained-glass window of pleasure only for the two of them. Her hands were dark purple ending in purple claws that desperately gripped Zoey, but only enough to mark, not to hurt her girlfriend. 

 

Rumi’s long tongue lulled out of her mouth, licking at the sweat on Zoey’s face as she rode out her orgasm inside of her, that one final touch being too much for their maknae as she let out a loud cry as she came with Rumi. Mira meanwhile was just enjoying the sight, continually hammering into Rumi with deep thrusts as she watched her girls come undone so beautifully beneath her,

 

“Fuck…!” Zoey cried out, her face red and streaked with sweat as Rumi thrusted lazily into her, trying to get her cock as deep as possible inside of Zoey before with a whimper she collapsed on top of her,

 

“Aww… all you got, tiger?” Mira purred as Rumi just panted, her face and body language saying all she needed to know as with a wet pop she pulled out of Rumi and quickly discarded the strap to the side as she laid down beside her two girls, “You did so well, Ruru…” Mira soothed before Rumi looked at her with needy, heat stricken eyes,

 

Taste,” Rumi pleaded through swollen lips as she looked at Mira, clumsily pawing at her girlfriend who chuckled,

 

“Of course, baby,” Mira purred as Rumi pulled out of Zoey in one quick motion, the black haired girl gasping loudly,

 

“Fuck…!” she panted, gripping the sheets as Mira scowled at Rumi,

 

“Oh come on, puppy, that wasn’t very nice…” Mira grinned as she forced her head down between Zoey’s legs, “Kiss her better, Rumi.” 

 

Rumi whined at being denied Mira, but the sound was quickly drowned out by the wet, hot sounds as she cupped her snout around Zoey’s folds and plunged her tongue in,

 

“Fuck Ru!” Zoey moaned sharply as she sat up, gripping the demon’s braid to steady herself, “Like how you taste in me…?” Zoey panted out with some effort before letting out a mind numbing moan as Rumi’s long, demonic tongue curled up inside of her, “Shit…!”

 

Mira grinned as she slid up behind Zoey, letting her brace against her chest as they watched Rumi devour Zoey’s pussy like she was a man lost in the desert finally finding water,

 

“Look at her go, Zo… such a good girl for us,” Mira purred into Zoey’s ear as she stroked her messy, black hair, “Let us hear you sing, Zozo…” 

 

Zoey moaned sharply as Mira tweaked her nipples, bucking her hips into Rumi’s mouth only to let out another mind-melting moan as Rumi gripped Zoey’s thighs to keep her steady before pulling her face out and licking at her lips and teeth,

 

“Fuck… good… good girl, Rumi,” Zoey panted as Rumi looked at the two with expectant eyes,

 

Hungry,” Rumi grunted out, her voice smooth and deep as she stalked closer from the bed, “Need taste…”

 

Mira smirked as she lifted Zoey off her lap and leaned up against the bedframe with her legs spread, “You’ve been so good for us, puppy, come and enjoy your treat…”

 

Rumi wasted no time in throwing herself between Mira’s legs as she plunged her tongue in completely, her ears flicking at the long, drawn out moan that was ripped from Mira’s throat,

 

“Fuck I wanna mix that into a song… just for us to know,” Zoey crooned as she moved to Mira’s side, her hands ghosting over her girlfriend’s body. One hand groping her tits, the other squeezing her hip, making sure every single inch of her was touched, 

 

“F-fuck… you…” Mira panted out as Rumi ate her out, the half demon rolling her tongue up inside of Mira to hit every single point as her new set of premaxillary teeth and elongated snout bumped against Mira’s sensitive clit, “Fuck…!” 

 

“We are, Mimi…” Zoey teased, tilting the pink-haired idol’s head to her and stealing a kiss from Mira’s breathless lips, “Or do you want more?” 

 

“You… you fucking brat,” Mira spat, but there she was all bark, no bite as Rumi’s ravenous appetite tore another moan from her throat, “Going to… fuck you are going to pay for this.” 

 

Zoey smirked as she tweaked Rumi’s nipples, before slowing gliding her hands up around Mira’s neck and squeezing,

 

“Oh I know… but doesn’t mean I’m gonna stop,” she said with a cheeky giggle as Rumi’s claws dug into Mira’s thighs, forcing a moan out of Mira as she was marked by their half-demon.

 

The two girls watched in awe as another thing in Rumi changed, a dark purple, patterned tail had grown from her tailbone, ending in a small tuft of Rumi-purple fur,

 

“Seems our tiger got her tail,” Zoey smirked as she leaned over, yanking the new appendage and grinning as Rumi recoiled from Mira’s folds with a loud whimper, her face fogged with heat and need and soaked with her own juices and those of her two girlfriends, “Good girl, we love when you sing for us, don’t we, Mimi?”

 

Zoey teased as Mira was drowning in the blissful aftermath of Zoey choking her and the absolutely rollercoaster of pleasure Rumi had thrust her onto,

 

“Don’t, fucking, stop, pet.” 

 

Mira spat as she yanked Rumi’s head back between her legs,

 

“I was so close you bitch…” she growled as Zoey chuckled, returning her attention to Mira’s chest as she worked in time with Rumi’s ravenous tongue and mouth to bring their beloved choreographer to the absolute peak of ecstasy. 

 

Between Zoey’s hands on her chest and neck, and Mira’s teeth and tongue, it didn’t take long at all for Mira to absolutely break

 

She looked beautiful as she came undone, her juices flooding around Rumi’s face as the half-demon lapped it up eagerly, growling for more as Zoey squeezed her fingers around Mira’s neck in time, leaving a beautiful necklace of marks from Zoey’s fingers. 

 

Mira collapsed back into the stack of pillows as Rumi licked at her lips, panting a few times before suddenly snapping back,

 

“What… I…” she panted, the absolute marathon of sex they just had catching up with the now fully present half-demon, “What the hell…!” 

 

Zoey and Mira sighed as they yanked Rumi between them, pressing a small kiss on each of her cheeks,

 

“Mmm, you’re gorgeous, baby…” Mira cooed as she rubbed Rumi’s side, the half-demon curling up to her as Zoey latched onto her back like a koala, 

 

“We love the look, Ruru…” she laughed lightly, stroking one of her horns gently, “You look gorgeous like this… and only we get to see our gorgeous puppy like this…” 

 

“But I’m-” 

 

“Shush,” Mira commanded, Rumi obeying with a small squeak, “It’s all temporary… besides… none of us are in a position to figure things out.”

 

“God yeah… I want to sleep,” Zoey murmured into Rumi’s neck as the half demon absentmindedly wrapped her tail around Zoey’s legs, “Aww… don’t want me leaving, Ruru?”


“I can’t control it…!” Rumi huffed out embarrassed as she hid against Mira’s neck,

 

“It’s okay baby… we’ll talk about it when we wake up, I’ll make your favorite blackberry pancakes tomorrow,” Mira offered,

 

“Promise?” Rumi mumbled out,

 

“Of course, baby,” Zoey smiled, “I’ll make the tea though, you don’t want to burn the pancakes again…”

 

“Good…” Rumi yawned, her eyes slowly fading back to her normal soft brown as she curled into Mira and Zoey as she slowly drifted off. 

 

“Goodnight, Rumi… we love you so much,” Mira purred, kissing between her horns as they slowly receded into her forehead,

 

“Love you too, Rums… sleep tight, tiger,” Zoey smiled as she and Mira exchanged one small, goodnight kiss before the pair drifted off to sleep alongside their girlfriend.
