Notes:

This first chapter, which I'm calling a prologue, was originally posted for a birthday event on my Tumblr. I'm including it because well, I love it, and it gives a good set up of what to expect in the following chapters.

Chapter 1: Prologue

Chapter Text

Picture this – you’re Chan’s girlfriend and he adores you, wants to give you absolutely anything and everything he has the capability of providing. He also loves to help his members, we all know that. So one night, after he’s fucked you stupid, you’ve lost track of exactly how many times he made you come, and you’re seconds away from falling asleep, your tongue is less guarded than usual and you confess to a fantasy about being a fuck toy for all the boys. He doesn’t get a chance to ask about it because you fall asleep before you finish your sentence.

He has an early schedule the next day, the kind where he leaves before you even wake up, and he can’t focus because now, every time he looks at the boys, he’s picturing them fucking you and he is a little surprised by how far from upset he is about it. This wasn’t something that had occurred to him and if it had, he might’ve thought he’d be too jealous to want it. But now, every time he hears their voices or glances over at them, he’s wondering if you’ll make the same sounds for them that you make for him. And if the dance they’re practicing has body rolls in it? Forget it, he’s gone. More than once he’s had to make them leave a room ahead of him so he can get his dick under control.

That evening, he gets back to your apartment completely frazzled and on edge. He doesn’t know if he wants to fuck you first, to get himself partly under control, or if he needs to talk to you about your confession. Somewhat unsurprisingly, considering the state you were in, he has to remind you of what you said. You don’t deny it, but now you look a little scared of his reaction. Is he gonna be all possessive like he gets sometimes? Does he think you’re disgusting? Does he think you’ve cheated on him? These thoughts are racing so fast in your head, that you don’t immediately notice how hard he is from thinking about it. A short while later, he has you on your back, buried deep in your cunt and he starts asking for more about this fantasy of yours.

You fell asleep, but I think there was more, wasn’t there baby?

Promise you won’t be mad?

How could I be mad at you?

It takes a while, but you get it all out. I want them to use me, whenever they want. Like when I’m wearing the necklace you gave me so you can fuck me whenever, wherever. I wanna do that for them too. Let them fuck me when I’m asleep after a long day like you do. Call me to the dance studio or recording studio ‘cause something’s not going right so you’re all stressed. Cockwarm Lixie or Minnie while he’s gaming. Fuck everybody during movie night. Ride Binnie’s thigh after a workout, when he’s still all sweaty. Let Jinnie paint me naked, then fuck him.

He can’t deny the way every scenario you bring up brings him closer to his own orgasm. After, when he’s laying on top of you, both trying to catch your breath, you whisper, most afraid of this part because you’re afraid he’ll think you think he’s not good enough. I’ll be happy with that, but I’d like to date them too, if they wanted.

You spend the next week or so talking about it, discussing boundaries – of which there are few and depend entirely on the individual guys – and how exactly you’re going to seduce each of them. You agree to a one-at-a-time approach, instead of just offering yourself up in the group chat, which had been your initial idea.

Jeongin, being Chan’s roommate, is first. The two of you “forget” when he’s going to be back so he “accidentally” walks in on you fucking in the living room. You reach out to him and Chan verbally invites him to join you and you get to learn exactly how good those fingers you’ve fantasied about feel in your pussy and your mouth while he fucks you.

Felix is next. You’re not sure what Chan told him to convince him to come over to your place instead of Chan’s, but they walk into your apartment for dinner together that turns into you splayed out on the kitchen table with Felix eating you for dinner and then confessing he’s had a fantasy about being between the two of you, one you’re both thrilled to fulfill for him.

Hyunjin was a little tricky. You weren’t sure he would go for it the same way Jeongin and Felix did, so you took him out first, seduced him slowly. Gentle touches to his arm or the nape of his neck the whole time you’re in the art museum, thighs pressed together at dinner after. He’s frazzled, feeling super awkward, and unsure what to think by the time you get to your apartment and then shocked when Chan asks how your date went, like it’s totally normal to date your friend’s girlfriend. The awkwardness vanishes the second you’re straddling his hips and sinking onto his cock, Chan watching from the chair in the corner of the room.

The gym the boys use at the company is being remodeled, really just getting new equipment so it’ll only be down for about two days. But Changbin’s complaining about not getting his cardio in on the right day, and how he doesn’t want to go for a run outside in the rain. So Chan suggests a different form of cardio. Which is how you find yourself face down, ass up, while the pair of them take turns until you’re a drooling, cum filled mess.

Seungmin is a bit more like Hyunjin, he’s not going to just jump into bed with you. He needs to be seduced and shown that he’s wanted first. He’s insecure, particularly if he starts comparing himself to the other members. So you look up schedules and plan to take him to a baseball game. He agrees, but calls Chan a few minutes later saying I think your girlfriend just asked me on a date.  She totally did. Did you not want to go out with her, ‘cause you should tell her now, she’s already picking out her outfit. His mouth goes dry at the shirt tight enough to show an imprint of your lace bra and short skirt combo you come out in when he comes to pick you up. You don’t know much about baseball, but he’s thrilled to explain it to you. And while, with a voice like his, you could happily listen to him read the dictionary to you, you love the look on his face when he’s explaining something he’s passionate about. Back at his apartment, the first round is just you two, but he takes a few videos to send to Chan. Then Lix gets home and joins you both.

There’s only Minho and Jisung left and you’re pretty sure you should go after them as a pair. You have all the others together, asking their opinions as well, and most of them agree, they’ve been called chopsticks before for a reason after all. Talking about it has gotten them all worked up though, which you’ve found isn’t a difficult thing to do. So, after settling on a straight forward date plan where you and Chan explain the whole thing to them first, Binnie has you held in the air, your back to his chest, his hands gripping your thighs and holding them open so the others can see exactly how well he splits you open. And so he can show off his strength. Felix, who’s sex drive seems to perfectly match yours, is already a whimpering mess on the couch before he sinks to the floor and crawls over to Hyunjin to suck his cock.

That is, naturally, when Jisung and Minho decide to wander into Chan and Jeongin’s apartment. You vaguely heard the commotion but, being too absorbed in Changbin, you didn’t really register what Chan and Jeongin tell the other two. After Binnie cums, filling you up, he passes you to Seungmin, who let’s you splay out on the floor with a perfect view of Jisung and Minho over his shoulders. Minho is pressed against Jisung’s back, one arm wrapped around his middle, lips close to his ear. You can’t hear what he’s saying, but you can see the effect it’s having on him. You watch Jisung’s eyes go glassy, his mouth drops open and little whines slip out. His hips roll forward, seemingly without his conscious control. Minho, meanwhile, has the wickedest smirk on his face, staring straight at you the whole time. It’s his eyes you’re looking into when you cum on Seungmin’s cock.

As soon as Seungmin moves, Minho lets go of Jisung who is on his belly, face between your thighs so fast you’re impressed he didn’t fall. Your thighs clench around his head and that seems to spur him on more, licking Changbin and Seungmin’s cum out of you faster. You hear whimpering above you and turn to see it’s coming from Felix, whose eyes are glued to Jisung and who looks rather jealous. Before you can say anything, Chan catches it too and you recognize the glint in his eyes. It’s going to be a long, but very happy night.

And it is. You don’t really hear the exact words Chan says, but the gist of it is that they’re going to pass you around and each of the eight of them is going to cum inside you. Then, Felix and Jisung are going to eat it out of you. You can’t tell who’s more turned on by that – you, Felix, or Jisung. After that, things get a little hazy for you. There are so many hands on you and you never go for more than a minute without a cock filling you.

Jisung slides into you as soon as he’s licked you clean. He doesn’t last long, but you already came on his tongue, so you don’t even notice that you didn’t come on his cock. At some point Jeongin has you bent over the coffee table, thrusting into you from behind. Chan, because he thinks it’s adorable when you’re completely fucked out, tries to get you to ride him. You manage to roll your hips, but you’re so far gone that he giggles and takes over, thrusting up into you. Felix lays you on your side on the couch, letting you relax as much as you can while he thrusts into you, keeping one leg bent up and over his legs so you’re on display for the others. You know, because you can taste it when he kisses you, that he’s sucked off at least one person other than Hyunjin. Part of you is sorry you missed that. You don’t remember when Changbin and Seungmin fuck you again, but you know they did. You heard Binnie grunting in your ear and calling you Bunny. You think that might have been after Jeongin, still bent over the coffee table. You know Seungmin likes to see your face, so that had to have been him on the couch, after Felix, with your knees pressed to your chest.

You know, because you heard it, that both Felix and Jisung have each been fucked at least once, probably twice. You vaguely think someone fucked Jisung when he was inside you. You want to make a mental note to make sure you can watch that next time, but the thought is pushed right out of your head.

Then Minho’s sliding into you on the couch wondering how a slut who’s already taken so much cock can still be so tight. Hey Hyune, got an idea, come here. Then Hyunjin’s fingers are sliding into you beside Minho’s cock and you’re so full, you don’t think you could be fuller, but you’re wrong. You practically scream when Hyunjin slowly slides his cock into your pussy, sliding alongside Minho’s. They let you adjust before setting a punishing, alternating rhythm.

Felix is already on his back on the floor, when first Hyunjin then Minho cums. Minho holds you up, supporting your upper body as he slides you down so you can sit on Felix’s face. You can’t see it, but you can feel their combined cum oozing out of you and into Felix’s waiting mouth. Judging from the sounds under and around you, it must look obscenely good. Then you feel Jisung’s tongue join Felix’s. You grip Minho, digging your nails into his arms as the pair wring one final orgasm from you.

You collapse and Minho gently maneuvers you to the floor between Felix and Jisung. The trio of you, gasping for breath and in a hazy, post-sex space that you love, lay there and wait for the others. Chan and Minho are giving out instructions. Hyunjin’s sent upstairs to run a warm bath. Seungmin and Jeongin are tasked with getting drinks and food and bringing them up to the bathroom, though they bring out a water bottle for everyone first. Chan helps you sit up and drink the water. Then he, Changbin, and Minho are carrying you, Felix, and Jisung upstairs to the bath.

Gentle hands are washing you, Felix is cuddled into your chest and Jisung is fighting sleep where he’s cuddled against Felix.

You, babygirl, are a genius Chan says to you, kissing your forehead and tucking you into bed between Felix and Jisung, after convincing the trio of you to eat some of the food Seungmin and Jeongin bring up.
