Your phone buzzed the second you had left rehearsals, and you didn’t even need to check the screen. Lexi had this way of finding exactly when your body was on the verge of collapsing, GIRLSET had just debuted on August 29th, and she was still running on adrenaline, but you could tell the lack of sleep was catching up. Meanwhile, you were rehearsing until your body screamed at you, with KATSEYE’s first trip to Brazil for Lollapalooza looming in just weeks.
And yet, no matter how exhausted you were, her name lightning up your screen had the same effect every time. A spike of heat in your chest and a curl of excitement low in your stomach.
Lexi ❤️ dorm is empty for a few hours come over
You bit your lip, sliding the phone back into your pocket as your manager called for you and a tiny thrill ran through you—this could finally be it.
— 1st Attempt
You had snuck into GIRLSET’s dorm like a teenager breaking curfew, Lexi was waiting for you, hair damp from a shower and she was wearing nothing but a baggy t-shirt and shorts that barely clung to her hips.
She grinned when she saw you, “You came fast.”
“Don’t start,” you muttered, shoving her shoulder as you kicked off your shoes. “We don’t have long.”
Her lips were on yours before the words even settled between you—hungry and desperate, the kind of kiss that made your knees weak. Her hands slid up your hoodie, tugging it over your head with impatience and you let her, your fingers threading into her hair as you pressed her back against the couch.
For once, there were no footsteps, no managers, and no alarms. Just her small gasp when you slid your thigh between hers.
“God, Y/n–” she breathed, grinding down without hesitation. You tilted her head back, trailing kisses down her neck and already dizzy with how fast you wanted her.
Her t-shirt was halfway up her body when the front door to the dorm burst open.
“Lexi! Where’s my charger?” Kendall’s voice echoed before she froze in the entryway.
You shoved yourself off Lexi so fast you almost fell as she pulled her shirt back down, cheeks flushed.
“What were you doing?” the nineteen year old girl asked, raising an eyebrow as she looked at the two girls on the living room couch.
“Uh nothing!” Lexi shouted, her voice cracking.
Kendall raised an eyebrow, smirking knowingly. “Right~, I’m just gonna grab my charger.”
She disappeared into her room, leaving the two of you breathless and burning.
— 2nd Attempt
The second time was at the KATSEYE house, the group had the rare luxury of a free evening with Sophia and Manon off at a recording session and Lara dragging Daniela, Megan and Yoonchae out for food.
Lexi showed up in a hoodie that was definitely yours, smirking when you tugged her inside by the wrist.
“You smell like me.” you teased.
“Maybe I like it that way.” she murmured, lips brushing your jaw.
You barely made it to the couch before you were on top of her, kissing hard and hands roaming freely. Her thighs spread for you without any hesitation, her breath hitching when your hand slid lower.
“Y/n,” she whispered, so soft it almost broke you.
You pressed your forehead to hers, heart racing, fingers brushing the waistband of her leggings.
“Yoonchae! Where’s my water bottle?” Megan’s voice carried through the house.
You both froze, Lexi slapped a hand over her mouth, her shoulders shaking in frustrated laughter.
You groaned, pulling back. “Why is everyone obsessed with water bottles and chargers the second we try something?”
She giggled, tugging you down for one more kiss before whispering. “We’re cursed.”
— 3rd Attempt
By the fourth week, it was almost comical. Every touch turned into a game of Russian Roulette—would you get thirty seconds of bliss or would someone interrupt at the exact worst moment?
One night, you thought you’d finally gotten lucky, Lexi had snuck into your hotel room after a long day of Lollapalooza rehearsals. The city outside your window pulsed with light, but the only thing you saw was her—hair messy, smile lazy, and body already crawling into your lap.
This time, she straddled you, lips hungry against yours and hips rolling in a way that made your head spin. Her t-shirt slipped, baring one shoulder, and you groaned, sliding your hands under the fabric—
Knock. Knock. Knock.
“Y/N? Sophia wants to run lines for tomorrow.”
You and Lexi stared at each other, wide-eyed.
“I’m going to lose my mind,” you whispered, forehead against her collarbone.
Her laugh was muffled, but her eyes were serious when she lifted your chin. “We need a plan. A real one. Somewhere nobody can walk in. Just us.”
Her thumb brushed your bottom lip, slow and deliberate. “Forty-eight hours. No managers. No members. Just you and me.”
And suddenly, the thought of a hotel wasn’t just tempting—it was necessary.
The black car pulled into the underground parking of a boutique hotel tucked away in Los Angeles, you hadn’t let go of Lexi’s hand the entire ride, fingers linked under the jacket draped across both your laps. Even now, as your manager’s voice buzzed in your memory.
“Be careful, don’t be stupid, and if you get caught—”
You only tightened your grip on the Hmongian girl’s hand.
Lexi looked at you with that same nervous-smug smile she always got when she was pretending to be braver than she felt. “We’re really doing this.” she whispered, the words caught somewhere between awe and disbelief.
“Two whole nights.” you murmured back, brushing your thumb across her knuckles. “No interruptions, no members barging in, and no managers knocking.”
Her giggle slipped out sharp and breathless, the kind that always made your stomach flip. “You’re making it sound like we’re about to rob a bank.”
“In a way,” you smirked, “we kind of are, but we’re stealing time instead.”
The elevator ride up was suffocating with anticipation, Lexi stood in front of you with her back pressed lightly against your chest, and you could feel her heartbeat thudding through her shirt. She didn’t say anything, just shifted closer as if the silence itself might snap if she didn’t.
When the door to the suite clicked open, Lexi bolted inside first, tossing her backpack onto the couch like she owned the place. You watched her spin in a circle, taking in the king-sized bed, the floor-to-ceiling windows, and the minibar. She looked so effortlessly young and free in that moment that you had to stop yourself from kissing her right there, tongue and teeth, desperate.
Instead, you leaned against the doorway and said softly, “So, this is us for the next forty-eight hours.”
Lexi turned, a slow grin crawling up her lips. “You say that like we’re not gonna be naked for at least half of it.”
Your laugh broke the tension, but only just.
The suite was quiet. Too quiet.
For weeks, every kiss you’d stolen had been ripped away by the sound of a door creaking open, a manager calling your name, a member’s footsteps down the hall. But here? Just the low hum of the minibar fridge and Lexi’s nervous laugh as she stood in the middle of the room, twisting her fingers together.
You leaned against the door after locking it, watching her like she was the only light in the place. “You realize we just checked ourselves into forty-eight hours of no excuses, right?”
Lexi’s lips curled into a grin, but it didn’t reach her eyes. “And you’re not even a little scared?”
“Of what?”
She shrugged, shoulders rolling under your hoodie she’d stolen. “Of us messing this up. Of me not being enough for you.”
That cut straight through your chest. You crossed the room in two steps, cupping her face in your palms before she could look away. “Lex, you’ve been enough since the first time you kissed me.”
Her cheeks flushed hot under your hands. She whispered, “Then kiss me again.”
The first kiss wasn’t frantic. It was slow, like you were relearning her mouth after months of shallow, rushed touches. She sighed into you, shoulders relaxing as she clutched your shirt.
By the time you guided her backwards to the bed, her knees hit the mattress with a little bounce, laughter spilling out of her like nerves breaking free. You pushed her hair back, kissing down her neck, tongue flicking the sensitive skin just below her ear.
She gasped, hands flying up to your shoulders. “Y/n—”
“Too much?” you murmured against her skin.
“Not enough.” she admitted, voice trembling.
The hoodie came off first, sliding from her body in one nervous motion. She crossed her arms over her chest, self-conscious, but you caught her wrists gently, kissing her knuckles.
“Don’t hide from me,” you whispered.
Her lashes fluttered, and slowly she dropped her arms. She was in a fitted tank, the kind that clung to her curves, and you traced the line of her collarbone with your lips, savoring how her breath hitched.
Your hand slipped under the hem of her tank, feeling the warmth of her skin. She arched into you like instinct, thighs shifting restlessly beneath you.
“Please,” she whispered, eyes closing tight.
You eased her back against the pillows, your body hovering above hers. One hand slid down, brushing her waistband, waiting for her nod. When she gave it, you pushed her sweats down slowly, inch by inch, until they were tangled around her ankles.
Lexi’s breath quickened, her thighs instinctively pressing together but when you nudged them apart, she let you, cheeks flushed so deep it spread down her neck.
“You’re shaking.” you murmured, kissing the inside of her knee.
“You make me nervous.” she admitted, voice small.
“Good nervous or bad?” you asked, looking up at her.
“Good…so good.” she whispered, her voice soft as her eyes met yours.
Your mouth trailed up her thigh, deliberately slow, until she let out a tiny whine. When you finally pressed your lips to the damp fabric of her panties, she jerked, hips twitching.
“Y/n—oh my god…”
You smirked, kissing her through the fabric, savoring how wet she already was. “I haven’t even started, and you’re falling apart.
She covered her face with her hands, but the sound of her muffled moan made your stomach twist with need.
Carefully, you hooked your fingers under the waistband, tugging her panties down her legs. Her thighs trembled when you spread them again, and you couldn’t help but whisper, “So fucking pretty.”
The first stroke of your tongue made her gasp, thighs clamping around your head. You pulled them wider, hands anchoring her hips as you licked another stripe, slow and deliberate.
Her hand shot down to grip your hair, tugging lightly as she whimpered. “Oh, fuck, Y/n—don’t stop, please don’t stop—”
You didn’t. You worked her slowly at first, teasing the sensitive spots until her hips were rocking helplessly. Then you sealed your lips around her clit, sucking gently, and she nearly screamed.
Her back arched, head pressed into the pillows, as moans tumbled out of her like she didn’t care who heard. “I can’t—fuck, I’m gonna—”
“Let go,” you murmured against her, sliding two fingers inside her at the same time.
Her cry cracked into silence for a moment before it melted into high, breathless gasps. She clutched the sheets, thighs shaking violently as she came undone, body writhing under your mouth.
When she finally stilled, chest rising and falling in sharp breaths, you kissed your way back up her stomach, hovering above her flushed face. Her eyes were glazed, lips parted as she tried to catch her breath.
“You okay?” you whispered, brushing hair from her damp forehead.
She nodded, voice barely there. “That was… holy shit.”
You chuckled, kissing her gently this time. “And we still have forty-seven hours left.”
Her laugh broke through her daze, weak but genuine, and she pulled you down into another kiss, whispering against your mouth:
“Don’t you dare stop now.”
The first thing you noticed was warmth. The sheets tangled around your legs, the faint heat of sunlight bleeding through the curtains, but mostly her.
Lexi was curled against you, bare skin pressed to yours, breath soft against your collarbone. Her leg was slung across your hips, her arm tucked against your stomach like she was afraid you’d slip away if she let go.
For a long while, you just lay there, heart thudding with something that wasn’t quite nerves and wasn’t quite peaceful. Last night kept replaying in fragments—her voice breaking when she came, the way she trembled in your arms afterward, the look in her eyes when she whispered don’t stop.
You brushed a strand of hair off her face, tucking it behind her ear. She stirred, eyelashes fluttering before she mumbled into your skin, “Stop staring at me.”
You smiled. “Can’t. You’re too pretty when you sleep.”
Her nose scrunched. “That’s cheesy.”
“And true,” you countered, leaning down to kiss her forehead.
Lexi groaned, hiding her face in your chest, but her lips curved into a sleepy smile against your skin. She stayed like that for a moment, then whispered so quietly you almost missed it:
“Did we just make everything complicated?”
The question punched through your chest. You thought about GIRLSET, KATSEYE, your labels, the cameras. All the rules you’d just broken.
But then she lifted her head, eyes glassy and nervous, waiting for an answer.
You tilted her chin until she was forced to meet your gaze. “No. We made it worth it.”
Her breath hitched, lips parting. And when she kissed you, slow and deep, you felt her whole body relax against yours.
It started with just a kiss, like last night, but soon she was crawling into your lap, tank top slipping down her shoulder, thighs bracketing your hips.
Her lips moved against yours, urgent but not rushed, and you felt her body already heating under your hands.
“You’re not sore?” you murmured, trailing kisses down her jaw.
“A little,” she admitted, cheeks flushed. “But I want more.”
Her honesty sparked through you like lightning. You gripped her waist, flipping her onto her back until she gasped, wide-eyed beneath you.
“Careful what you ask for,” you warned.
“I’m not scared of you,” she whispered. “I trust you.”
That broke you open.
You kissed down her body, pulling her panties aside before pressing your tongue against her clit. She jolted, thighs squeezing your head, a strangled moan slipping out.
“Y/n—oh fuck—” Her fingers tangled in your hair as your tongue worked her, slow at first, then harder, deeper, until she was gasping your name like a prayer.
You slid two fingers inside her, curling until her back arched clean off the bed. Her cries filled the room, raw and unfiltered, and you didn’t let up until she broke apart, shaking and sobbing your name.
You barely gave her time to come down before tugging her into your lap. She blinked, dazed, as you guided her knees to straddle your face.
Her entire body froze. “You want me to—?”
“Yes,” you rasped, settling back against the pillows. “Ride me, Lexi.”
Her cheeks flamed, but she lowered herself slowly, and the second her wetness touched your tongue, she screamed.
Her hands shot to the headboard, knuckles white as her hips jerked. You gripped her thighs, holding her steady as you licked deep, sucking her clit until her cries grew high-pitched and desperate.
“Y/n, I—fuck—I can’t—”
“Don’t hold back,” you groaned against her.
She broke, grinding down helplessly, moans spilling out of her throat until her body shook violently above you. She collapsed forward, forehead pressed to the wall, panting like she’d just run miles.
You pulled her down beside you, kissing her swollen lips as your legs tangled. You pressed your thigh between hers, then shifted until you were lined up perfectly.
Lexi gasped when your slickness met hers, hips jerking. “Oh my god—”
“Move with me,” you whispered.
The first grind had you both crying out, clinging to each other as your clits dragged together. You moved slowly at first, rolling your hips in sync, but soon Lexi was chasing the friction, moaning into your mouth as your thighs slapped together.
Her nails dug into your back as the pace quickened, the wet heat of her against you making your head spin. When she came, she screamed into your shoulder, and the sound alone dragged you over the edge with her.
Steam curled against the glass, the water pounding down as you pressed her to the wall. She trembled in your arms, head tipping back as your fingers slid inside her again, your mouth sucking a mark on her throat.
Her moans echoed in the shower, water streaming down her flushed skin. “Y/n—fuck—I can’t believe this is real—”
You kissed her hard, pumping your fingers faster until she cried out, body convulsing under the spray.
When she sagged against you, spent, you held her close, rinsing her hair with gentle hands.
Hours later, she lay sprawled across the bed, hair damp, skin marked with your love bites, body trembling with exhaustion. You curled up behind her, kissing her shoulder, pulling the blanket over both of you.
“You’re ruined,” you teased softly.
She hummed weakly, too tired to argue. “You broke me.”
“And?”
“And I liked it,” she whispered, lips curving into a smile before she drifted off, tangled in your arms.
Forty-eight hours. No managers. No members. No interruptions.
Just you and Lexi, wrecking each other until neither of you could breathe.
