It was just another day at work for the girls and Ateez as they were all backstage getting ready for one of the many showcases to come as Y/N was touching the last parts of makeup and clothing as Y/N double checked the guys as they filed out to stage Y/N grabbed onto Yunho’s his shirt sleeve making him making him stop where he was by the door snapping his attention to the small girl “ I didn't get to put tint on you yet” Y/N said letting go of his sleeve as he made a oh expression before bending forward so he was leveled with her short demeanor as his breathe that smelled of mint from brushing it minutes prior fanned in her face as he said “ let's hurry , we have to be on in 5” giving a quick nod grabbing the lip tint off of the makeup bench as well as a fresh brush she then applied tint to his lower lip as her eyes were fixated not realising she bit down on her own as she watched how the brush glided over his plump lips making her start to ache between his legs as she thought about how his lips would feel if he went down on her, she snapped out of her thought trailing her eyes back to his giving a smile once more “ you're all done.”Y/N said as they both exchanged a quick bow as they both made it to backstage two minutes left before the group had to go on. The girls watch them perform and how sexy Mingi and Yunho looked as they were up there, Y/N couldn’t help the neediness she felt between her legs begin to grow more. not taking her eyes off both boys Y/N said “ Hey I think I’m going to go back to the fitting I’m not feeling that well.” Y/N said shifting in her spot, her friend looking at her in concern “ Are you okay, are you feeling sick.” Her friend said, patting Y/N’s back.
Y/N nodded her head “yeah I’m just kinda tired, wake me up when the boys are finished yeah.” Her friend nodded, waving as Y/N walked back to the fitting room. She started packing up her tools, putting it in her work bag before laying down on the mini couch against the far corner of the room facing the vanities that sat across from it. Y/N sighed as all the music could be heard from the stage her eyelids grew heavy as she only got a couple hours of sleep the night prior caused by Mingi coming over in need of help for his “stress” from their comeback as well as his hiatus, her hands roamed over all the sensitive marks he left on her inner thighs making sure not to go any higher to pleasure herself knowing if she got caught punishment from Mingi would be unbearable having learned once making her wet as the recalled that nights experience , she doses off minutes later only to be woken up Mingi slightly shaking her awake “ Y/N hey it’s time to go, everyone has already left.” He said, making Y/N wave her hands telling him to go away. “Let me sleep, Mingi, I hate you for making me tired all the time.” She says trying to turn away from him making Mingi chuckle “Little one watch what that pretty little mouth of yours says.” Mingi says moving Y/N’s legs making her sit up next to him so he could sit down with her. She glares at him saying “ Or what? You won’t do anything.”
She says in a way to test his patience as she got off the couch walking towards the vanity that had her packed up work bag as Mingi followed behind her putting one hand on her hip gripping it tightly pushing his hips harshly onto her ass as his other yanked her hair back making her look at him in the mirror tilting her head to the side so her neck was exposed to him “ You really think I won’t fuck your tiny holes right here until you beg me stop.” Mingi says grinding harshly into Y/N’s ass Making her moan at how good the bulge in his jeans felt rubbing against her thin skirt, letting go of her hair traveling down her side untucking her shirt as she unbuttoned it so he could take it off making her moan as he continued to lick and nip at her neck leaving little marks as her shirt fell to the floor as his large hands removed her bra before finding its way to her breast pinching her now hard nipple due to the cold air.“ Mingi Please stop, someone is going to see us.” Y/N says putting her tiny hand on top of his that was holding her hip in place causing him to look up from kissing up and down her neck “Why are you scared someone’s going to see how much of a little slut you really are hmm. ” He says with dark eyes pulling her by the arm away from the vanity back to the couch he pushed Y/N to the floor so she would sit on her knees as she watched how Mingi’s abs flexed as he took off his shirt the neediness pooling between her thighs as she slowly rubbed her fingers again her soaked panties as the friction from before is now gone making her whine throwing her head back making Mingi snap his attention to the tiny girl, he felt his pants get tighter every second he continued to watch how her skirt hike up to her stomach while she continued to rub her clothed pussy “Little one, what was daddy’s rule about touching yourself without permission.” Mingi said, taking his pants off as he sat down on the couch his words made Y/N remove her hands quickly from herself with a whine looking back at him with pleading eyes “ Daddy won’t let me cum as punishment.” She says with a pout crawling to sit between Mingi’s legs he picks her up placing her in his thigh holding her hips in place as Y/N starts to rock her hips against him making them both groan she pries one of his hands off her bringing his long digits up to her lips. She takes one into her mouth sucking on it as she stares back at him with pleasure filled eyes as he pushes his finger farther down her throat making her gag “Is this my little sluts way of saying I should let her cum?” He says pulling his finger out of her bring his hand to her nape pulling her face closer to his kissing her harshly.
Y/N felt her orgasm coming close when he felt his thigh flex under her as she continued to ride him with the feeling of his tongue explore every spot in her mouth she pulls away “ Daddy I’m close please let me cum,daddy please” pleas leaving her lips as mingi pulls her hips down farther on his thigh making her Yelp as she came on his leg resulting in Mingi grabbing her throat making her get off him and onto the floor between his legs “ Are you that sensitive from how good I fucked that pretty little cunt of yours last night.” He says taking his boxers off, slapping her in the face with his hard cock, as her tiny hands grab onto his dick giving kitten licks to his tip that leaked pre cum, she looked back up into his darkened lust filled ones as she licked him from the base of his cock to the tip not breaking eye contact as she kissed it making him groan “ I’m sorry daddy, I didn’t mean to, I’ll be good little cum slut now I promise.” She says before she takes all of him into her mouth feeling his tip hit the back of her throat resulting in Mingi throwing his head back with a groan with his long fingers lace into her hair pushing her head down further making her nose hit his base. As her head bobbed up and down needily she felt him twitch in her throat showing he was close to his release He pulls her lips off of him with a popping sound with strings of saliva and precum still connecting her mouth to his cock “ Is this what my little whore was worried about, getting caught being a filthy slut.” Mingi says, grabbing her cheeks, turning her face to look at Yunho who was standing with a smirk in the entryway making Y/N moan as Yunho watches the naked girl trying to catch her breath. Yunho looked over at Mingi saying “You weren’t lying when you said she was a slut. She’s so pretty on her knees.” Mingi smirked saying “If you come over she’ll give you a good sucking. Won’t you little one?” Y/N nodded her head fairly quickly causing Yunho to chuckle saying “Man she’s a cock whore isn’t she?” Y/N looked up saying “Can I please suck his cock? I’ll be good!” Mingi looked back down saying “It’s not up to me little one. You have to ask him.”
As Mingi was talking to Y/N Yunho came into the room, closing the door and locking it, giving them sometime to be alone before having to go back to the dorm where they would be interrupted every 5 seconds. Y/N looked over at Yunho saying “Can I please suck your cock..-“ Yunho looked down at the tiny girl who was now in front of him saying “Call me sir.” Y/N smiled saying “Can I please suck your cock sir?” Yunho smiled at the tiny girl saying “Of course little one. I can't wait to feel that pretty mouth of yours.” Mingi was still standing besides his best friend saying “Use her however you please. I’ll be over there. Little one, what's your color?” Y/N looked up saying “Green daddy.” Mingi nodded his head saying to Yunho “She uses the stoplight method.” Yunho nodded his head saying “Alright. Now little one take it out. Show me what your mouth can do.” Y/N unbuttoned the blue jeans, she was now a pro at due to her having to help Mingi anytime he was “stressed out”. Y/N looked up to ask Yunho if she could suck but was cut off with Mingi shoving her head down the the base of his friends cock causing him to hit the back of her throat saying “You’re taking too long little one. Show him how good you can make him feel, quit playing around!” Yunho threw his head back moaning while lacing both of his hands in her hair. He looked back down seeing Y/N was still holding him to the back of her throat saying “No gag reflex? How did you pull her?” Mingi shrugged while jerking off saying “She came to me. Literally. It was late at night at her apartment when we had a few too many drinks. Little one. I need some assistance over here.” Y/N pulled her mouth away from Yunho’s cock seeing her dried tear stained face with mascara running down her cheeks from him teasing her earlier saying “I’m sorry daddy.” She says crawling on all fours back to Mingi while Yunho watches how Y/N’s ridden up skirt showing her well rounded ass as it sways over towards the other male. Y/N licks his cum off of his hand and stomach before she takes Mingi’s dick into her hands, pumping him before taking him back into her mouth she moaned, sending vibrations to Mingi cock as she felt repeated sharp pains on her ass from Yunho's large hands leaving red marks behind. Mingi said “She’s a good slut. Aren’t you little one? no hands, we've talked about this.” Y/N kept their hands on Mingis cock while Yunho gave her a harder slap in her ass saying “Why aren’t you listening to him little one? Are you wanting to get punished? I’m not as nice as your daddy in front of you.”
Y/N moaned onto Mingis cock again as yunho's hand connected to her bare ass harder than before. Yunho looked at his friend saying “Is it alright if I punish her?” Mingi shrugged his shoulders saying “Knock yourself out. Just ask her what color she’s on during and after. I don’t want her to get too overwhelmed.” Yunho nodded grabbing the tiny girl off of Mingis cock saying “You know little one I was going to try and be gentle with you but it looks like I can’t since you don’t want to listen I guess I have to make you listen.” Yunho pushed the girl onto the vanity counter top that was in front of the mirror. He yanked down her skirt and underwear all in one go causing her to suck in a breath due to the cool air hitting her wet folds. Yunho tsked at the sight saying “Who got you this wet?” Y/N moaned out a “Daddy and you sir!” Yunho grabbed the girl's cheeks harshly, turning her head towards the mirror, his thumb grazing her swollen bottom lip before saying “I couldn’t hear you, little one. Say it again.” Y/N looked in the mirror locking eyes with Yunho who was pressed up behind her and then at Mingi who was jerking himself off sitting on the couch saying “Answer him.” Y/N then yelled out “DADDY AND YOU SIR!” Yunho smirked at the girl slapping her ass with his free hand saying “That’s a good slut!” Yunho moved his hand from her cheeks to her throat saying “Such a cock hungry slut. Who would’ve thought you would be like this.” Yunho let that hand that slapped the tiny girls ass travel down to her wet folds dragging a finger up and down causing Y/N to push their hips back impatiently. Mingi looked at the girl saying “You being impatient little one isn’t going to make him go faster. If he doesn't prep your tight cunt you won’t be able to handle the both of us.” Yunho says pushing his long digit into her tight entrance making him groan at how tight she was around his finger he adds another finger into her making them both moan as he curls his fingers before doing a scissor motion making Y/N’s legs weak as she tried to find the stability she rests her tiny hand onto Yunho’s wrist that was gripping her neck “ Sir, please let me cum sir please.” She says as she moves her hips against his hand that was still inside of her “ what color are you, little one?” He asks with pumping his fingers faster into the tiny girl making her body shake as the knot in her stomach got tighter and tighter, her words not able to reach her lips as she tries not to cum until told to do so. That resulted in
Yunho to pull his fingers out making her whine at the loss of contact “ when I ask you a fucking question I expected you to answer, now what’s you fucking color slut.” He says as he pinches her sensitive bud making her scream, throwing her head back on his shoulder replying “ Green it’s green sir.” Yunho let’s go of her throat revealing little dark purple spots on her neck as his go and giant hand envelop her breast pinching her nipple as his other hand pushes her body forward before his large hand grips her tiny thigh lifting it up to rest on the vanity with the rest of her “ Good then no you may not cum, now be a good whore and take my fucking cock won’t you hm.” Yunho says as he teases her entrance with his tip before pounding into her not giving her time to adjust to his length making her mouth fall agape as she tried to keep pace with him “ mmh sir.. let.. cumhm…” was all Y/N could muster feeling his huge length stretch her tiny walls he continues his fast pace hitting her sweet spot repeatedly making her body start convulsing as she tried to withhold her release made tears form in her eyes as he continued to pound into her “ Fuck dude when you said she was tight, I didn’t know she would be like this.” Yunho says to his friend that was sat behind the both of them watching. she felt his dick twitch inside of her making her lose her mind “ please sir! I’ll do anything just let me cum please sir!” Y/N cries out holding on to what little sanity she has left from how much pleasure she was feeling “fine you may cum.” Yunho says, making her eyes roll to the back of her head as her tear stained face cries out, finally feeling her release as Yunho continues to pump into her riding out both their orgasms. Yunho thrusted two more times before pulling out causing Y/N to almost fall due to the orgasm she just had Yunho caught the girl saying a little nicer “Hey little one what’s your color?” Y/N nodded their head swallowing the spit the collected in their mouth saying “Green still.” Mingi walked over saying “My turn.” Mingi grabbed ahold of the tiny girl holding her up whispering in her ear saying “There’s only one person that can make you cum how you want to and who is it?” Y/N moaned at the soft touch Mingi had on her saying “You daddy.” Mingi looked in the mirror locking eyes with the fucked out girl saying “That’s right little one.” Mingi turned the girl around lifting her up so that way she didn’t have to stand anymore setting her down on the counter top causing her to gasp a the cool feeling that was now on her ass. Yunho was now sitting down where Mingi was at watching everything unfold.
Y/N looked into Mingis eyes saying “I need your cock daddy. I want to feel full. I need you to fuck sirs cum and your cum into me please.” Mingi caresses the girls side saying “Are you sure about the little one? Because I’m not going to be holding back.” The girl gave him a pout while nodding her head hearing Yunho in the background saying “You’re a yes man aren’t you? You give her what she wants. You need to start being strict on her. If she were mine she would be taught so many lessons.” Mingi turned his head saying “She isn’t yours though is she?Know your place when you talk about what is mine.” Mingi put his focus back onto the girl who is now pulling his fingers up to her mouth sucking on them. In that moment Mingi gave her no warning and shoved his cock into the tiny girl she never seems to stretch out no matter how many times they had fucked. He’s always goes deep hitting her g-spot without any effort his thrusts getting rougher than usual he’s always gentle with a fast pace but right now he went deep with harsh thrusts as his intense feeling of his friend having more power over Y/N was making him jealous as she felt Mingi tear through her. He placed his large hand on her throat lightly squeezing while his other guided her small hand to feel her lower stomach as he was deep inside of her she could see and feel him poke out through her lower abdomen. Yunho got off the couch and towards his friends on the vanity “ Is she though, she seems to take me like she wants me more, right little one, do you like the way I fuck that tight pussy of yours better.” Yunho retorted looking at Mingi then back at the fucked out girl who couldn’t even speak from all the pleasure she’s in she replies with a loud moan as she cums.
Mingi stared into the girls eyes saying “Who’s are you little one? Mine or Yunho’s?” The girl was finally able to utter out a word that they could understand but it wasn’t what they were expecting “Both.” Yunho looked at the girl surprised saying “Say that again little one.” Mingi was still pounding into her making her voice staggered saying “Both! I’m both of yours!” Mingi looked down at the girl saying “You know little one I heard your little conversation over the phone a couple days ago with YF/N about how you’ve always wanted both holes filled up and about how your toys that I got you aren’t doing it for you anymore. You know when I bought you those I just bought it for us to use or for you to use when I’m on tour. But it looks like you’ve been using them when I’m at home thinking about this tiny cunt right here.” Mingi snapped his hips against the poor girl causing her to scream out in pleasure saying “I’m sorry daddy!” Mingi hummed at the girl saying if you’re so sorry why don’t you take the both of us and tell us who fucked you the best.” Mingi pulled out of the girl causing her to whine at the loss of friction. Yunho picked up the girl while Mingi walked over to the mini sofa sitting down. Yunho looked at the girl who’s body already limp from the first three orgasms. He picked her up saying “Can she handle the both of us right now?” I mean I can wait until we get back to the dorm or back to her apartment.” Mingi held out his hand grabbing Y/N pulling her to his chest saying “Little one can you handle the both of us? I don’t want to force you.” Y/N looked into Mingis eyes saying “I can handle both of you. I’m ok my body just needs a moment. But don’t be surprised if I have the both of you take care of me tomorrow.” The two chuckled letting the girl take a moment of rest until she said she was ready. Yunho then said “Who do you want where?” Y/N looked at the boys saying “I want Yunho in my pussy and I want Mingi in my ass.” Mingi pushed the girls hair away from her face saying “Are you sure this is what you want?” The girl nodded her head saying “Yes daddy.” Mingi kissed her forehead, getting up saying “Ok little one.” Mingi held the girl waiting for Yunho to sit down on the sofa. Once he sat down Mingi set Y/N down on the floor helping her walk over to Yunho who was now hard as a rock.
Y/N climbed on top of the tall man slowly sinking herself down on his cock causing them both to let out a moan. Yunho let the girl take her time making sure she was going at her own pace he then said “God how can you be so tight after being fucked twice.” As Yunho talked to Y/N his cock touched g-spot causing her to throw her head back in a moan letting Yunho see all the marks from Mingi and him on her neck. He smiled saying “That’s a good girl. Taking all of my cock like this. It just makes me want to destroy you.” Yunho pulled the girl to his chest so that way Mingi could get her prepped. Y/N tried to start moving but Yunho held her down making her whine he then said “If you can stay like this while Mingi preps you I’ll fuck you hard little one. I promise.” The girl mumbled into his neck saying “Ok sir.” Yunho caressed the girl's back, dragging his fingers up and down her back, causing her to relax a bit more up until Mingi dripped some cold lube on her ass making her tense back up especially in her pussy. That caused Yunho to moan out saying “Little one relax please if you do that again I won’t be able to fuck you like I said I would.” The girl nodded her head quickly causing the man below her to chuckle. As Mingi prepped her by fingering and scissoring her Yunho mumbled sweet nothings into her ear making sure she stayed relaxed.
After Mingi finished he slowly pushed himself in making the girl gasp at the stretch she wasn’t used to. Mingi was only able to get the tip in when he said to Yunho “You can start fucking her I need her to be relaxed and that’s probably the only way I’ll be able to get in.” Yunho nodded his head snapping his hips up into the girl having them both let out a moan. Mingi was pushing himself into her while Yunho was fucking the girl from beneath. Mingi gave the girl sometime to adjust to him until she gave the ok to move. As the two boys found a perfect pace for the both of them Y/N held her head in both pain and pleasure. Mingi grabbed ahold of her hair yanking her head back latching onto her neck making more marks for her body while Yunho put a nipple in his mouth swirling it around with his tongue with the other nipple in his fingers pinching and pulling it around. Yunho looked up at the girls face while it contorted in pleasure, he could feel that she was on her way to her fourth orgasm just by the way her velvety walls felt around him. Mingi let go of her hair making her fall into his friends chest both. Yunho took the chance to catch Y/N’s lips, Mingi took the opportunity to start pounding into the girl slapping her ass having her moan into yunhos mouth saying “More please. I need more.” Yunho pulled away his right hand automatically going to her throat saying “Does our little cock slut need more? Huh?” The girl nodded her head due to her not able to get out a word all because the two men were pounding into her relentlessly. Yunho gave her face a little love tap saying “What have I told you about your words little one.” That caused Mingi to get riled up more making him slap her ass harder saying “I’ve told you multiple times to use your words but you’re still not using them. I guess I have to keep punishing you until you do.” Y/N threw their head back screaming “Yes I need more!” Mingi and Yunho looked at each other smiling the both of them snapped their hips into her at the same time keeping the same fast pace and hard thrust with each other making the girl shake uncontrollably between them. They we’re finally reaching the edge Mingi could feel the girl tightening up having him say “Do you need to cum little one?” Y/N knew if they didn’t answer the man behind her with her voice they wouldn’t let her cum so she decided to moan out saying “Yes please daddy.” Mingi groaned “I’m getting close too. Just hold on a bit longer.” Yunho being in the same boat as the other two said “I’m getting close too.” The two men’s thrusts were starting to get sloppy as they were chasing after their own climax.
Yunho was the first break cumming deep inside of the girl, Y/N made sure to milk the man underneath her of all his cum. Yunho pulled out of her at that point Mingi took the opportunity to move from her ass to her tight cunt making sure to keep his best friends cum in her but also making sure to make her cum as well as himself. Mingi was on his final thrust when he felt her walls tighten around him he knew she was on her fourth and final orgasm. He grabbed her cheeks turning her head to him kissing her while cumming inside her just like his friend did. Mingi pulled out of the girl holding onto her while his friend got up from the sofa getting dressed saying “Go get a rag so we can get out of here before they suspect anything.” Yunho nodded his head getting dressed before walking out of the room to go find a rag. Mingi set the girl down on the sofa laying her down crouching down in front of her saying “You did so well little one. I’m proud of you.” Mingi held the girls face in his hands she nuzzled into his palms mumbling a thank you. Yunho then came back in with a warm wet rag saying “I’ll clean her up you get dressed.” Mingi mumbled an ok before getting dressed himself making sure to keep an eye on his friend to see if he was doing the proper after care to the girl. Mingi always made sure she got enough kisses and affirmations after sex because the both of them always went harder than expected. Mingi was genuinely surprised as his friend was doing exactly what he does to the girl when they’re alone. Yunho made sure he took care of the girl by asking her what Mingi does for aftercare and also making her laugh. After Yunho finished cleaning up the girl Mingi grabbed his backpack that had spare baggy clothes like sweats and sweatshirts that the girl mainly wears at the dorms
He got her dressed and put her on his back saying “You ready to go?” Y/N nodded their head saying “Yes I’m ready but I need my bag.” Yunho then said “I already got it come on let’s go before we get in trouble.” Mingi looked over at the girl who’s head was on his shoulder saying “Hold on tight because I’m about to run.” Y/N gripped harder letting the man know that she listened to him and with that they ran out of the arena and to the cars that were waiting outside for them. The manager saw the three and yelled “WHERE WERE YOU GUYS WE GOT TO GO NOW!” Yunho said back finally coming up to their manager saying “Sorry we got caught up!” The girl on Mingis back was passing out slowly that was until San said “They were fucking Hyung! I heard them while we were walking out of the arena!” The three gave him the dirtiest look ever only to have the manager say “Just get in the car I don’t get paid enough for this.” The three got into the car in the back row Mingi put the girl in between the two of them and within seconds the girl passed out laying on Mingis chest with yunhos jacket draped over her body.
