ok hear me out, maybe? sub space yeji, i would love to give her the strap for her birthday, maybe after dancing it out at the club or sth w the girls, yall had a few drinks but only enough to help loosen up a little bit, and the way she was all up on u on the dancefloor makes u impatient to get home and just wreck her respectfully, but she definitely feels the same way (🎂)
this is exactly what i wanted to write !!
i feel like she'd have something simple like champagne if the girls or you bought a bottle for her birthday, she's not really about getting drunk, but she likes the taste of it. so she has a glass or two and quickly drags you across to the dance floor. the others have already dispersed around the place, way drunker than the two of you.
you can't think straight from the beginning because of the dress she's wearing. it's pink, sort of a satin material that brings out every curve of her body, not to mention the black, thin straps that accentuate her shoulders and collarbones. you can see her best when she's facing you and swaying her hips to the beat, and you hope your body is acting on it's own, that you're not standing there staring at her but your body moving to the beat too, unlike your brain that could only process her looking edible right then and there.
when she turns around however, grinding her ass against your crotch, you can't think of anything else but being home and having her under you letting out the prettiest moans and whines. not even two hours later you're left to assume she's on the same page, because as soon as the song that the two of you were almost dry humping to ends, she turns around and tries to say something in your ear that with the music at a first try is difficult to understand.
"what was it baby? i didn't quite hear" you try to get closer, hands on her hips to make sure she doesn't stumble and fall anywhere, and part of it to just be close to her.
"can we go home?" her voice is soft, mainly shy when asking you, but you were able to catch the desperation in her voice as she looked at you with her pretty eyes, waiting for an answer.
"are you sure? it's still early" you remind her, looking for the girls anyways.
"please" she's too shy to tell you exactly what she wants, but her hand in yours and the way she pleads at you with her eyes is more than enough for you to understand.
"okay, yeah" the last thing you do is peck her lips, looking for ryujin, tonight's designated driver before letting her know you'd be taking an uber home early, probably because she's the only sober one, but she catches up right away, sending the two of you a wink and assuring you she'd take care of the other two.
as soon as you get home, she doesn’t even allow you to turn on the lights. yeji drags you with her to your shared room, attaching your lips as soon as you step inside. she lets you press her against the door, your hands roaming up her thighs and lifting her dress with them. she whines just at how hard your lips moved against hers, her fingers wrapping around your sides and squeezing any parts of your body she could when you press your thigh against her center.
"so this is why you wanted to come home, huh?" your lips graze against her own as you speak, you're so close you can even breathe each other's air.
"please" her eyes are stuck on your lips, she wants to kiss you more, she wants you to do so many things to her right now, but you're taking your sweet time teasing her.
"please fuck me." you don’t reply, but instead walk away from her eliciting a few whimpers at the loss of contact. she’s free to walk around the room, and even wait for you on the bed if she wants, she knows that, but she still waits for you to drag her along after you’re done. you’ve made sure to tie the strap nicely around your thighs and waist, leaving just your matching underwear on.
you know exactly what she wants, how she wants it, everything. and she smirks a little when you slowly take off her dress, kissing all over her neck and chest leaving a few marks in between, before laying her on her stomach at the end of the bed. yeji hums in  satisfaction when you press kisses behind her ear, and lower to her nape…. all the way down her back, before you reach her thong. she pushes her ass up and tries her best to look back at you when you drag it down her legs, pressing kisses to the back of her thighs too.
and quickly after you’re back up, one hand to her side to hold you up and the other spreading her wetness around while you kissed her, taking advantage of the way her head was tilted for better access.
“everything’s okay birthday girl?”
“yes.. just do it please” yeji pushes her hips back, moaning when the tip of the fake cock grazes against her entrance before you pull away
“i do it” she huffs after that, quickly giving up on doing anything herself and instead waiting for you. you didn’t make her wait long tho, smoothly pushing the head between her folds making her gasp loudly, fisting the sheets and looking back at you. “relax baby”
“fuck” she throws her head forward now, letting out pretty moans and whines at how you’re fucking her in the right places and you’ve just started, so don’t be surprised if it flatters your ego a bit. “harder. fuck me harder please”
“like this?” your hands grab on to her hips and you can both quickly hear the slapping of skin, and yeji immediately feels how much harder you’re thursting inside her, groaning pretty sounds for you.
“you’re so pretty like this baby… so needy.” you gather her hair into a ponytail, wrapping it around one of your hands before tugging it softly and eliciting a louder moan than the ones you’d caused before. “you like that?”
“do it again” she pleads, her words interrupted because every time your skin slaps against hers her voice cuts off and is replaced with a gasp. “you feel so good- so fucking good.”
but you just hum and tug at her hair one more time, also spanking her ass in the process. that itself probably elicits the loudest moan out of your girlfriend you’ve heard all night. she’s so worked up already, chasing only her (hopefully) first orgasm of the night as she backs up her ass to you in an attempt of speeding things up.
“im not gonna go anywhere baby, slow down” she relaxes at the kisses you press behind her ear after reassuring her
“i know” she huffs, pout on display in the most endearing way as she keeps getting interrupted by soft moans you provoke with each snap of your hips. “but i want to cum”
you chuckle at her stuttering, and then her whining when you pull out and detach yourself from her. she thinks its some sort of twisted joke and that you’re not letting her cum on her birthday. which would mean all that perfect behavior was for nothing, but her thoughts are easily interrupted when you turn her around, kissing her pout as you slowly push her legs up against her chest.
yeji hums slightly when you finally push back in, so easily because of how wet she was. her hands at her sides bunch the sheets as you slowly start snapping your hips against her. her moans increase the closer she gets, and in the end, all she needs is your thumb lazily rubbing her clit to push her over the edge.
unlike other times, she quiets down, lets her breath hitch and eyes roll back as the orgasm rakes through her. but as soon as she’s calm, your girlfriend immediately looks for you, hands palming the mattress for your skin and the moment she’s able to peck your lips a couple of times, the two of you can’t help but giggle, looking at the bright red clock on her wall and thinking of how many more times you can make her feel like that before ryujin comes home with the others..
