...

Stuck in the elevator, my sister swallowed my cum

Picking up Lila always made me late. Not for anything important, just, whenever my mom texted and said, “Can you get your sister?” I’d feel like I should actually leave five minutes early, then I’d waste it looking for my keys or a clean shirt, and arrive at the curb just in time to see Lila already outside, arms crossed, blowing air through her nose like a bored racehorse.

That night, she waited beneath the porch light at Kira’s house, balanced on the step like she was daring someone to trip her. It was almost midnight. She had her phone in one hand and her tote bag in the other, thumb scrolling with boredom. The porch light hit her hair and made it look even blonder than usual. Her skirt was new, a denim number cut high and scalloped along her thighs. On top, she wore a long-sleeve tee with a neckline so loose it kept sliding off one shoulder, revealing a pink bra strap, which was basically a middle finger to Mom’s “dress like a person” routine. I didn’t even want to think about the rest of the outfit, but my brain did it anyway.

She looked up when she heard my Civic’s exhaust, not even smiling. I killed the headlights and let her get in before I rolled the window down.

“You look like you killed someone,” I said.

“Just my dignity,” she replied, dropping the tote at her feet and peeling her hair off the back of her neck. “It’s hot as balls in there. Kira’s A/C is a lie.”

She yanked the seatbelt, snapped it in with unnecessary force, and gave me a side glance. “Could you at least try to look less like a serial killer behind the wheel?”

I flicked my eyes at her, made a face, and started the drive. In the rearview, I saw her make a dramatic show of fanning herself with her hand. Her bare thighs squeaked against the seat. The skirt had no business being that short, every time she moved, I got a flash of soft thigh, the muscles tensed in little waves, and sometimes a triangle of the black shorts she wore under. I shouldn’t notice. It would have been easier if she didn’t spend all her time crossing and uncrossing her legs, or if she didn’t keep tugging at her shirt to adjust her cleavage.

She caught me glancing once, in the turn lane at 11th. “Dude, you’re not even subtle,” she said, voice bored. “I know you’re looking at my chest.”

“It’s basically all you wear now,” I said, playing it off. “I’m not sure you own shirts that aren’t see-through or falling apart.”

She snorted. “Like you’d notice if I wore a parka. You look at the same two things every time.”

I didn’t answer. She wasn’t wrong. It had become a thing between us. Not some scandalous, forbidden tension, but more like a running joke we were both too lazy to retire. Lila liked to point out that we were twins, not just siblings, and therefore genetically mandated to annoy the shit out of each other. I’d decided a long time ago that if she wanted to win the sibling arms race, she could have the crown.

The rest of the ride was quick: city blocks blurring past, empty intersections, occasional streetlights that made her skin look almost gold. At the apartment building, she shucked her bag up to her shoulder and hopped out before I’d even parked. I followed her in through the lobby, which was still hot and humid even with the big fans by the doors. The kind of heat that sits on your skin, sticks you to your clothes, makes you regret everything you ever ate or drank.

Lila stabbed at the elevator button and waited, shifting from foot to foot. “You can walk, you know,” she said, not turning around.

“I’m trying to remember the last time you thanked me for a ride,” I said, standing next to her.

“That would imply you had a choice.” She grinned. “Mom would’ve had your head if you bailed.”

The elevator clunked down to the lobby, doors yawning open with the usual sickly rattle. Inside, it was smaller than a phone booth and somehow even hotter than the hallway. The metal walls looked sweat-slick. I stepped in after Lila and pressed “6.” She slumped against the mirrored side and let her head flop back, eyes closed.

Halfway between floors two and three, the lights flickered and the elevator jolted, grinding to a stop. There was a pop like someone breaking a finger, and then silence.

We both stared at the number panel.

“Did you do that?” Lila asked, opening her eyes.

“Yeah, I control the elevators with my mind.” I punched the door open button, but nothing happened. No motor, no movement, not even a beep. “It’s probably just a breaker.”

Lila huffed, then hammered the emergency button. The speaker crackled, but no voice came through.

“This is the part where you panic and I have to slap you,” I said.

“Fuck off. If I die in here, I’m haunting you first.”

She mashed the emergency button again, then dug out her phone and tried to check for service. Two bars, barely. She fired off a text to Mom, stuck in elevator w/ idiot, help and looked at me.

“It’s gonna get gross in here,” she said. “I’m already sweating.”

I leaned against the opposite wall. Our knees almost touched, and with every second the air felt thicker and denser I looked at her, trying not to stare, but she really did look like she belonged on a billboard. Full lips, flushed pink from the heat. Hair escaping in wild frizz from her ponytail. The loose shirt still falling off her shoulder, almost down to the line of her bra, which seemed to inch higher with every movement.

She licked her lips, caught me looking, and raised one eyebrow. “You can drool if you want. Might cool you off.”

“I’m good, thanks.”

We stood in silence. The elevator didn’t even hum. It was a dead machine, like a coffin that someone forgot to bury. After a minute, she slid down to the floor and pulled her knees up, skirt riding almost comically high. I stayed standing, arms crossed, pretending I had better things to do than watch her adjust herself over and over.

Another few minutes, and she sighed. “I’m starving. I didn’t eat at Kira’s because her stepdad kept hovering.”

“You want my wallet?” I offered, half-sarcastic.

“Do you have snacks in there?” She shot back.

She let her head fall back again, exposing her neck. There was a little mole I’d never noticed before, just under the angle of her jaw. I found myself staring at it instead of her chest for once. She stretched out her legs, then tugged at the hem of her skirt like it would do anything to cover her thighs. She really was hungry, her stomach made a little growl, which she tried to mask with a cough.

The heat got worse. I rolled up my sleeves, but it didn’t help. I checked the panel again, just in case, but all the buttons were dead. Lila’s phone buzzed, but she just glanced at it and set it face-down on her knee.

“Mom says someone’s on the way,” she said, voice flat. “Said it could be, like, forty minutes. Probably more.”

I looked at the tiny fan in the ceiling. It wasn’t moving. “We might actually die in here.”

“At least you’ll die with a boner,” she said, nodding at my crotch.

I looked down and, sure enough, the khakis were betraying me. Not fully hard, but there was no hiding the outline, not in this lighting and not in this position. I tried to think about anything else: baseball, dead puppies, that time Mom caught me jerking off in the laundry room. but all of it just made it worse. The silence didn’t help. Every movement, every shift, just made the fabric press tighter.

Lila raised her eyebrows, gave me a little smirk, and leaned back on her hands, arching her back so her chest stuck out even more. “Are you really this easy?” she asked, almost clinical.

“It’s hot, that’s all,” I said, lying.

She gave a short laugh, then scooted back against the wall and fanned herself again. “Don’t pass out. If you faint, I’m pissing on you.”

I grunted and sat down opposite her, legs stretched out. The elevator was so small our feet almost touched. She stared at me, and I could feel the heat coming off her skin. Her knees parted a little, toes pointing at me.

Five more minutes passed, maybe ten. Her shirt was soaked at the collar, sticking to the inside curve of her boobs, and I could see the outline of her bra through the thin fabric. She stared straight ahead, her jaw clenched like she was working out a math problem.

We lapsed into silence again. I fiddled with the laces on my sneakers, tried to ignore the fact that I was basically at half-mast just sitting across from her. She stretched again, this time raising her arms over her head, making her boobs press up against the damp shirt. She noticed me looking and smirked.

“It’s too cramped,” she said after another minute. “My legs are going numb.” Before I could answer she pushed herself up, stepped over my feet, and dropped straight onto my lap, facing away from me. The sudden weight and the heat of her body hit at the same time. Her ass settled right against my crotch, the thin denim of her skirt and whatever she had underneath doing almost nothing to hide the contact. She wiggled once, getting comfortable, and the movement dragged her ass slowly across the exact place I was already half-hard.

I sucked in a breath.

“Jesus, Lila—”

“Shut up, there’s nowhere else.” She leaned back a little, settling deeper. Another small grind, almost like she was testing it. I felt myself get fully hard under her in seconds. She didn’t move away.

My hands went to her waist on instinct, fingers spreading over the soft skin just above her hips. The shirt had ridden up. I could feel the warmth of her through it. She didn’t tell me to move them.

“I’m still starving,” she muttered, head tipping back against my shoulder. “This is the worst night.”

I tried to keep my voice steady. “Wish I could help.”

She was quiet for a second. Then she shifted her hips again, grinding back against the hard length trapped under her.

“You could,” she said.

I frowned at the side of her face. “What?”

“You could help.” Her voice was calm, almost bored, like she was suggesting we share a granola bar. “I could suck you off and swallow your cum. It’s filling.”

I stared at the mirrored wall in front of us. “You’re insane.”

“I’m hungry.” She rolled her hips once more, slow, and I felt the pressure drag along the entire underside of my cock. “And you’re already hard. It’s right there. Don’t act like you haven’t thought about it.”

“Lila, we’re twins. We’re stuck in an elevator.”

“So?” She turned her head just enough that I could see the edge of her mouth. “No one’s coming for at least half an hour. I’m bored, I’m hungry, and you’re leaking through your pants. It’s practical.”

I opened my mouth to argue and nothing useful came out. Her ass was still pressed against me, and every small movement sent another pulse of heat straight through my stomach. She felt me twitch under her.

“See?” she said. “Your body already voted yes.”

I tightened my hands on her waist, not pulling her closer, just holding on.

“You’re actually serious,” I said.

“Dead serious.” She reached back, found one of my wrists, and guided my hand a little higher under the edge of her shirt so my fingers brushed bare skin. “I’ll even make it quick if you’re scared. You just sit there. I’ll do the work.”

I should have said no. I should have pushed her off and gone back to staring at the dead control panel. Instead I sat there with my twin sister on my lap, her ass grinding slowly against my cock, and felt the last of the resistance drain out of me.

“…Fine,” I heard myself say.

She didn’t gloat. She just nodded, like we’d settled on who was paying for gas, and started to slide off my lap and turn around between my knees.

“It’s not a big deal,” she said, voice almost bored. “People do worse shit on the internet.”

I couldn’t speak. My heart was thudding so hard I could feel it in my teeth. I looked at her hand, her fingers curled just barely against my leg.

She hooked her fingers in my waistband and pulled my boxers down. My dick popped free, hard as it had ever been, flushed and leaking. She looked at it, then up at me, then back at it, and smirked.

“Jesus, bro. You could have warned me.”

She wrapped her hand around the shaft, fingers closing tight, and gave it one long stroke. The sensation almost made me come on the spot. Her hands were softer than I expected, nails painted a faint pearly white. She stroked me again then leaned in and licked the tip.

I flinched. She grinned.

“I haven’t done this a lot,” she said, “so tell me if it sucks.”

She didn’t wait for a reply. She opened her mouth and took the head in, lips sealing around it. Her tongue was hot, slippery, and she ran it over the ridge, sucking lightly. Her hand kept stroking the shaft, moving in slow, steady pumps.

I tried to watch, but the sensation made my eyes roll back. I gripped the metal handrail behind me to keep from bucking up into her mouth.

She bobbed her head, taking more of me in each time. I watched her hair slide over her shoulder, the muscles in her arm flexing as she stroked me. Her mouth was small but stretched, cheeks hollowed out with each pull.

She looked up at me, eyes sharp and clear, and I felt a jolt go through my stomach. The sight of her, on her knees in that tiny elevator, sucking me off like it was nothing, made me dizzy.

She took me deeper, lips stretching around the shaft, tongue pressing hard along the underside. Every few strokes she pulled back just enough to breathe, then sank down again, wet and steady. The soft wet sounds filled the small space. I could feel the heat of her mouth, the tight seal of her lips, the way her hand twisted lightly on the base every time she came up.

My free hand found the back of her head without thinking. I didn’t push, just rested it there, feeling the movement of her ponytail against my fingers. She hummed once around me and the vibration shot straight up my spine.

“Fuck, Lila—”

She didn’t slow down. If anything she got more focused, cheeks hollowing, taking me as deep as she could without gagging. Spit ran down the side of her hand. The mirrored wall behind her showed everything: the top of her head bobbing, the curve of her back, my own face looking like I was about to pass out.

The pressure built fast. I tried to warn her, voice rough.

“I’m close—”

She only tightened her grip and kept going. When I came it hit hard. Thick pulses flooded her mouth. She stayed locked around me, swallowing immediately, throat working as she took every shot. Even after the main spurts stopped she kept sucking, lips sealed, tongue working, pulling at me like she was trying to drag out whatever was left. The sensation was almost too much, over-sensitive and sharp, but she didn’t let up until I was twitching and empty.

Only then did she pull off, slow. A thin string of spit and cum connected her bottom lip to the tip for a second before it broke. She swallowed once more, wiped the corner of her mouth with the back of her hand, and sat back on her heels, breathing a little harder than before.

I stared at her, still half in disbelief.

“You feeling better now?” I asked, voice low.

Lila looked up at me, eyes steady, and gave a small, almost satisfied nod.

“Yeah,” she said. “Not as hungry anymore.”

Then the elevator lurched without warning. The lights flickered, the motor hummed back to life, and we started rising again.

Lila scrambled up, smoothed her skirt, and wiped her mouth one more time like nothing had happened. I shoved myself back into my pants just as the doors opened on the sixth floor.

We stepped out in silence. She walked a little ahead of me toward our door, tote bag over one shoulder. Halfway there she glanced back.

“Next time I’m hungry,” she said, “you’re on snack duty again.”

“With pleasure,” I said, knowing damn well I wanted her to suck me off again.
