PART 1 PART 2 PART 3 PART 4
you get home from work, walking into your apartment you share with your childhood best friend, sam. your families always wanted you guys to get married, but you turned out lesbian, and now you're the best roommates ever.
"hey you wanna come on a ski trip next weekend?" he greets you with an excited smile. "it's me and the guys, and some of their friends i'm not that close with, we just wanna get out of LA for a bit."
"hmm let me think about it," you start. "that sounds... anxiety inducing."
"no you have to come, y/n! i promise it'll be fun!" he protests.
you knew you needed to meet some more people; ever since moving to LA, you'd been so focused on working. you'd become pretty close with sam's friends and they were awesome, but you did want to expand your horizons a bit.
"will there at least be other girls there? i don't want to intrude on your 'guys trip'," you ask, concerned.
"yeah, yeah, they said they're bringing some," he reassures you.
you sigh, "okay fine, i'll come."
"YESSSS," he cheers, we're renting a big house in the mountains, it's gonna be chill."
it's friday afternoon; you're carpooling with sam and some of his friends to the house they booked, music blasting and vibes at an all time high.
as you pull into the driveway, you see there are already 4 other cars there, and your nerves start to settle in. the house is huge; there must be way more people on this trip than you expected.
you all walk in, greeted by excited yelling and many hugs. you say hi to the few familiar faces you see, and getting overwhelmed by the amount of unfamiliar ones, you decide to go find somewhere to put your stuff for the moment. you drop it in an empty bedroom with two twin beds, hoping you and sam can sleep in there, and return to the crowd.
everyone was sitting around the living room now, seeming to be playing a drinking game but mostly laughing and chatting, and you find a spot to sit near some of the guys you know. sam hands you a drink and sits next to you, and you turn to him muttering, "you didn't tell me this many people were gonna be here," with a jokingly angry expression.
"i know, i had no idea, i'm sorry!" he apologizes and you giggle. "did you see who's over there, though?" he gestures across the large room with a subtle tilt of his head.
you look across, scanning everyone's faces before you see one you recognize all too well. it's none other than billie eilish.
you turn back to him with wide eyes, "oh. my. god," you say under your breath. "how did she end up here?"
"apparently some of those guys have been friends with her for a while and she said she needed a break from the city," he explains, and you stare at him, speechless. "... but aren't you glad i made you come here?" he smirks, teasing because he knows how huge of a crush you have on her.
you roll your eyes and try to hide your blushing cheeks before turning back to the conversation happening next to you. you can't even pay attention because you're so distracted by the fact that you're in the same room as her.
you know you shouldn't be this shocked; you were in LA with a bunch of people you didn't know, after all. you were bound to have a run-in with a celebrity one of these days, but to be staying at the same house as one of your biggest celebrity crushes felt surreal.
after a few hours of chatting and drinking, it was getting late, and some people started to disperse, mainly the couples, when some guy stands up and shouts, "LET'S MOVE THIS TO THE HOT TUB!"
everyone agrees, laughing at his enthusiasm, and gets up to go get their swimsuits on. you head to the bedroom your stuff was in, and realize it's locked. not only is it locked, you can hear faint sounds of one of the beds creaking repetitively. you're not knocking on that door.
you look around and catch sam about to go into a room to change, so you whisper-yell, "SAM!" getting his attention and motioning 'come here.'
"my stuff is locked in there. and listen..."
his eyes widen in amusement, lifting his fist up to bang on the door, but you grab it, stopping him.
"STOP! that's so embarrassing, i'll just chill on the couch while you guys go in the hot tub," you say, giggling.
"y/n don't be lame, i'm sure you can borrow a swimsuit from someone," he protests.
"no it's ok, i don't see any girls around anyway..."
like clockwork, billie rounds the corner of the hallway you're whispering with sam in, and sam, stirring the pot, exclaims, "hey! can she borrow a swimsuit? hers got locked in a room."
your stomach drops. 'i'm gonna kill you,' you try to threaten him telepathically.
but she hears the sounds from the door and lets out a belly laugh, saying "yeah of course, my stuff's upstairs," motioning you to follow her.
your heart is pounding as you follow her, when she looks back asking, "what your name? i don't think we've met," with a friendly smile on her face. she looks even prettier up close.
"i'm y/n," you smile nervously, not knowing if it would be weird to ask her for her name, since everyone knows it, but she responds, "i'm billie, nice to meet you."
"you too, thank you so much, i put all my stuff in there and forgot about it when people started going to bed."
she laughs, "no problem. yeah these people are horny as fuck," getting a laugh out of you too.
she leads you into the small bedroom where her bag sat on a twin bed, and she opened it, digging through for her bikinis. she held one up before turning around to look at you, scanning your chest through your tank top and then hers, and laughed hesitantly, "i don't think any of these tops are gonna fit you very well, but we'll make it work."
you laugh, trying not to have a heart attack at the fact that billie eilish just looked at your boobs, and say "yeahhhh i'm kinda lacking in that department," cupping them and blushing.
she notices immediately and says, "no no, they're a perfect size," catching herself staring at them again and darting her eyes back up to your face. you notice her pale face turning red now too, "mine are just huge," she continues, trying to laugh the tension away.
after more nervous giggling from both of you, she pulls a different one out and says, "here try this one, i can tie it tighter for you if you need," handing it to you.
"ok perfect, thank youuu," you say, now trying to decide if it would be weirder to leave and find a bathroom to change in, or to change in there with her. girls change in front of each other all the time, right? suddenly you can't remember.
before you can come to a conclusion, billie pulls her tank top off right in front of you and puts on a hot pink string bikini top. you make your way to the end of the bed to put the swimsuit she gave you down so you can take your clothes off as well, planning on doing it as fast as humanly possible.
as soon as your tank top comes off, leaving you exposed as you weren't wearing a bra under it, she laughs, "actually thank god you're in here, can you tie this?" she steps closer before turning her back to you, holding the strings out for you to tie.
"yeah, of course," you giggle nervously, tension brewing in your stomach at the fact that she just saw you topless. taking the strings from her hands and tying them in a delicate bow, you ask, "is that good?"
"yeah that's perfect," she says, turning around and tapping your bare waist twice, as if to say thank you.
you start to put the triangle-shaped top she gave you on, tying it around your back, and lifting the fabric up to cover your front. it was so baggy, you could practically see your nipples from the fabric sagging.
"uhhh, can you... help me?" you ask timidly, holding the straps up and feeling helpless.
she turns to face you after slipping her bikini bottoms on, giggling at your state, saying, "yeah, turn around for me?"
you turn your back to her and hand her the straps, and she fiddles with them for a moment before turning you back around to see if it looked any better.
she looked down at your chest, giggling, "y/n, you might be skinny dipping tonight."
"BILLIE! i'm not doing that!" you laugh, and she raises her eyebrows, purses her lips, and looks away suggestively before laughing again.
"i'm kiddinggg, here, let's try the thing where you put it on upside down, i think it might fit better," she suggests.
you stare at her in confusion, "i have literally no idea what you're talking about."
she giggles, "people were doing it on tiktok a while ago, come here," reaching her hand behind your back, and pulling the strings undone. she slips the top off of your body, trying not to notice your hardened nipples, and thinks for a second about how to tie it.
you feel so exposed, standing so close to her in such little clothing. you could practically feel her breath on your bare chest, when she says, "ok wait, i'm gonna tie it around your neck first, hold your hair up for me?"
you follow her directions, gathering your hair, and she slips her hands over your shoulders, tying the straps so that the fabric hung at a good length. the touch of her fingertips on the back of your neck was sending electric currents through your body, and you were trying your hardest to stay relaxed.
she finishes tying the top part and you let your hair down, before she starts fiddling with the triangles of fabric, sliding it around to cover you. in the process, her fingertips graze over your nipples slightly, making you twitch, hoping she wouldn't notice, but she giggles, "sorry, i feel bad, i'm like groping you right now," blushing.
you giggle, feeling your cheeks turn beet red, and say, "no, it's ok, anything to not have to break into that room," both of you laughing.
once she's satisfied with how the front looks, she picks up the strings and reaches around your back to tie them, her face impossibly close to yours. there's no way she can't feel your tension, but she's doing a good job at ignoring it. she adjusts the front one more time, before admiring her work and tugging at it to make sure it's secure.
she smiles up at you, saying, "ok, i think that should be good, now get your bottoms on so we can go play in the hot tub!" giving your hip a light slap and giggling. you slip your pants off, hoping there's not a visible wet patch from everything that just happened, and slide the bottoms she gave you on.
you start to re-tie one of the sides to make it tighter, and she grabs the other side, saying, "here let me help you so it's faster, everyone down there probably thinks we're fucking in here," letting out a chuckle.
you gasp, "oh my god!" looking at her inquisitively. "why??"
"as soon as sam told my friends you were coming, they got so excited and showed me your instagram, and i said i thought you were pretty," she muttered the last part under her breath, shyly.
you didn't even know how to react, so you matched her energy and jokingly groaned, "oh my godddd, everyone always wants to play 'lesbian matchmaker'," rolling your eyes before whispering, "i think you're pretty too," and looking away with a smirk. you don't know where this confidence is coming from; you weren't even very drunk, just a little tipsy.
you said that right as you both finished tying your swimsuit bottoms, and in response, all she can do is smirk (and blush, hard), giving you a gentle slap on the butt and saying, "come on missy, the hot tub is waiting," guiding you out of the room.
