The cardboard box was heavier than it looked. Liam shifted it against his hip, fumbling with the key card, and the door swung open into a room that smelled like stale air and someone else's Febreze. He dropped the box on the stripped mattress, took a breath. The walls were the color of weak coffee. A window that faced the parking lot. A desk with a gouge in the corner. Standard issue. Fine. He could be invisible here.
He unpacked methodically—jeans folded into the bottom drawer, hoodies on the middle shelf, textbooks stacked by the desk lamp. His laptop. His phone charger. A small bag of toiletries. Everything ordinary. Everything designed to say I'm just a normal freshman who definitely does not have a latex balloon collection tucked under his bed.
He'd wrapped them in a t-shirt. A black one, nondescript. Fifteen balloons, all unopened, all smooth and cool to the touch. He'd slid the bundle into the back corner of his closet, behind a pair of sneakers he never wore. Safe. Hidden. No one would find them. No one would know.
The wall beside his bed was thin. He'd noticed it when he'd toured the room in August—the way the RA had knocked on the adjacent door and introduced the empty space as "your neighbor's room, still being painted." He'd pressed his palm to the particleboard and felt it give, just slightly. Cheap construction. The kind where you could hear a pin drop. Or a balloon squeak.
He was trying not to think about that.
He was failing.
His phone buzzed. A text from his mom: Did you unpack your sheets?
He typed back: Yes. He had not unpacked his sheets.
The afternoon stretched. He hung a poster—a band his roommate's brother had recommended, some indie thing he'd never actually listened to—and arranged his desk lamp at the perfect angle for studying. He was just sliding his laptop into its designated spot when he heard it.
A voice. Muffled. But close.
Through the wall. From her side.
His hands went still.
"—and then he just stared at me, like, for a full ten seconds, and I was like, dude, it's a balloon, not a grenade."
A laugh. Bright. Contagious. The kind of laugh that made you want to hear it again.
Liam's pulse picked up. He told himself it was nothing. She was talking to someone—a roommate, a friend on the phone. Normal. People talked about balloons. Balloons were normal. Everyone encountered balloons at parties, at fairs, at—
A creak.
Soft. Rubber against rubber. The unmistakable sound of latex being stretched.
His breath caught.
It was a small sound, barely audible through the wall, but he knew it. He knew it the way a musician knows a wrong note, the way a chef knows when something's burning. His fingers twitched on the edge of his desk.
The creak came again. Longer this time. A slow, deliberate stretch.
And then—silence.
He held his breath. Waited. The silence stretched, elastic, and he felt his ears heat, his cheeks warming despite the empty room. He was blushing. Alone. At a sound through a wall.
Get a grip, Porter.
He forced himself back to unpacking. Grabbed the box of toiletries, carried it to the bathroom. Ran the tap until the water ran cold. Splashed his face. Stared at his reflection in the mirror—gray-blue eyes, hair falling into them, cheeks still pink.
You're fine. You're normal. She's just—playing with a balloon. People do that.
He didn't believe himself.
Back in his room, he sat on the edge of the bed. Listened. Nothing. Just the hum of the building's heating system, the distant thud of a door closing somewhere down the hall.
Then, from the other side of the wall: a soft gasp.
Not surprise. Not fear. Something else. Something that made his stomach tighten.
The creak again. Faster now. A rhythm. Stretch, release, stretch, release—
His mouth went dry.
He knew that rhythm. He'd done it himself. In his childhood bedroom, door locked, headphones in, a balloon between his palms. The slow squeeze, the pressure building, the way the latex warmed against his skin—
Stop. Stop thinking about that.
He stood. Paced to the window. The parking lot was half-full, cars with out-of-state plates, parents unloading trunks. Normal. Everything was normal. He was a normal freshman at a normal university, and the girl next door was just—
Another gasp. Higher this time. Almost a whimper.
His jeans got tight.
He pressed his palm flat against the wall. The particleboard was warm, vibrating faintly from the bass of her music—something pop, something upbeat, the kind of song you'd hear at a party. But beneath it, that creak. That stretch. That sound he knew better than his own heartbeat.
She was playing. Right there. Three inches of cheap construction away.
He pulled his hand back like the wall had burned him.
His face was on fire. His whole body was on fire. He couldn't breathe.
There was a knock at his door.
He froze.
Another knock. Three quick raps, friendly, insistent.
He crossed the room in three strides, pulled the door open—and there she was.
Honey-blonde waves tumbling past her shoulders. Hazel eyes, warm and bright. A smile that could light up a football stadium. She was holding a balloon—a red one, latex, fully inflated, tied off with a neat little knot. She twirled it between her fingers like it was nothing.
Like it was just a balloon.
"Hey!" she said, her voice exactly as bright as it had sounded through the wall. "I'm Chloe. Your neighbor. Figured I'd say hi before I start being annoyingly loud."
She grinned. Her eyes flicked down to his hands—and stopped.
He followed her gaze.
He was still holding the balloon.
The red one. The one he'd pulled from his pocket without thinking, the one he'd been clenching in his fist while he'd been listening to her through the wall. He'd grabbed it from the closet. When? During his pacing? During his panic? He didn't remember.
But it was in his hand. And she was staring at it.
His face went scarlet.
"I—" he started. "That's—it's not—"
Her grin widened.
"Nice balloon," she said. Her voice was casual. Her eyes were not. They were sharp, tracking the way his fingers curled around the latex, the way the knot pressed into his palm. "I like red."
He opened his mouth. Closed it. Opened it again.
Nothing came out.
She laughed—that same bright, contagious laugh—and reached out, tapping the balloon in his hand with one finger. It wobbled. He felt the vibration through the latex, through his skin, all the way down his spine.
"I'm Chloe," she said again, like she hadn't already said it. "And you are?"
"Liam," he managed. His voice cracked. He wanted to die.
"Liam," she repeated, tasting the name. "Nice to meet you, Liam."
She held his gaze for a second longer than necessary. Her eyes dropped to the balloon again. Then back to his face. Her smile turned knowing.
"Well," she said, "I'll let you get back to unpacking." She stepped back, still holding her own balloon. "But if you ever want to, you know, hang out. Or whatever. I'm right next door."
She winked.
And then she was gone, her door clicking shut, her laugh echoing in the hallway.
Liam stood in his doorway, frozen, the red balloon still clutched in his fist. His heart was hammering. His ears were burning. His jeans were painfully tight.
Through the wall, he heard her voice again—soft, playful, singing along to the music.
And then: the creak of latex.
He closed his door. Leaned his forehead against it. Breathed.
She knew. She had to know. The way she'd looked at the balloon, the way she'd smiled—she knew.
He looked down at the balloon in his hand. Red. Shiny. Perfect.
His thumb found the knot. Traced it.
Through the wall, the creaking continued. Faster now. A rhythm he recognized.
He wasn't alone.
The thought sent heat pooling low in his belly. He pressed his palm flat against the door, listening. Her breath, soft and quick. The squeak of latex against skin. The sound of someone who knew exactly what she was doing.
His fingers tightened around the balloon in his hand.
He couldn't hear her music anymore. Just the creak. Just her breath. Just the thin wall between them.
He turned. Looked at his closet. At the t-shirt-wrapped bundle in the back corner.
Then at the wall.
The creaking stopped.
Silence.
He held his breath, waiting. One second. Two. Five.
Then, soft as a whisper: "Good night, Liam."
His heart stopped.
He stared at the wall. At the cheap particleboard. At the space where her voice had come through.
She knew his name.
She'd said his name.
Through the wall.
He pressed his palm flat against the surface, felt the warmth of her side bleeding through. His fingers spread. His forehead dropped to the wall.
"Good night, Chloe," he whispered back.
There was no answer. But he didn't need one.
He was still holding the red balloon when he finally turned off the light.
Chloe closed her door and leaned against it, her own balloon still warm in her hand. She pressed her lips together, fighting the grin that wanted to split her face in half.
He'd been holding a balloon.
A red one. Shiny. Fresh out of the package, probably, because there wasn't a single wrinkle on it. And he'd been standing there in his doorway, frozen, his ears so red they looked painful, his gray-blue eyes wide and panicked, and he'd been holding a balloon.
Her balloon.
Well. Not literally. But the one she'd heard through the wall, the one she'd imagined him touching, the one she'd pictured between his long fingers—that one.
She pushed off the door and walked to the center of her room, the balloon dangling from her fingers. She could still feel the heat of his gaze on her. Could still see the way his throat had moved when he swallowed.
God, he was cute.
She'd known, of course. From the first night, when she'd heard the faint, careful creak of latex through the wall, she'd known. She'd pressed her ear to the particleboard, holding her breath, and listened. The rhythm was unmistakable. The soft, reverent sound of someone handling something precious.
She'd been doing the same thing on her side, her own balloon stretched between her palms, her eyes closed, her lips parted.
For a week, they'd been playing this game. She'd pop a balloon, and he'd go quiet. She'd stretch one, and she'd hear his breath catch through the wall. She'd whisper to herself, pretending she was alone, and she'd hear him shift in his chair, his feet shuffling on the floor.
She knew he could hear her. She'd known from the start. But she'd kept playing anyway, because the thought of him listening—of him sitting there, his ears red, his hands trembling, his own balloon forgotten in his lap—made her wet.
And now she'd seen him.
She dropped onto her bed, the springs groaning under her weight. The balloon bounced on her stomach, and she caught it, pressing it against her chest. The latex was cool against her skin. Smooth. Perfect.
She closed her eyes and replayed the moment: his face when he'd opened the door, the way his eyes had dropped to the balloon in her hand, the way his fingers had tightened around his own. The way he'd stammered, his voice cracking on her name.
She'd said his name back. Liam. She'd practiced it in her head a dozen times, but saying it out loud, watching his eyes widen—that had been something else.
He'd looked at her like she'd caught him doing something forbidden. Like she'd seen inside his closet, inside his head, inside the part of him he kept hidden.
She had.
And she wanted to see more.
She sat up, the balloon still pressed to her chest. Through the wall, she heard him moving. His footsteps, soft on the carpet. A drawer opening. Closing. Then silence.
She pressed her palm flat against the wall. The particleboard was warm, probably from his hand on the other side. She imagined him standing there, his forehead against the surface, his breath shallow. The same way she'd been standing a minute ago.
"Good night, Liam," she'd whispered. And he'd answered. She could still hear his voice in her ear, soft and rough, like he'd been holding his breath.
She smiled. A slow, wicked smile that spread across her face like heat.
She lifted the balloon to her lips and kissed it. The latex tasted clean, slightly bitter. She didn't care.
Then she stretched it between her hands, the familiar creak filling the silence. She pulled it taut, felt the resistance, the tension. She ran her thumb along the surface, feeling every millimeter of latex under her skin.
She wondered if he was listening. She hoped he was.
She brought the balloon to her mouth again, this time letting her lips part, letting her breath fog the surface. She imagined his hands on it instead. His fingers tracing the same path hers were tracing. His mouth, warm and hesitant, pressing against the latex.
Her thighs pressed together.
She set the balloon aside and lay back on the bed, staring at the ceiling. The light from the hallway bled under her door, casting a thin orange line across the floor. She could hear the faint hum of the vending machine down the hall, the distant murmur of someone's TV.
And through the wall, his breathing.
She turned her head, looking at the particleboard. At the spot where she knew his bed was, on the other side. He was probably lying there too, staring at his own ceiling, thinking about her.
She hoped he was touching himself.
The thought sent a jolt through her, sharp and electric. She bit her lip, her fingers finding the hem of her shirt. She pulled it up, exposing her stomach, the cool air raising goosebumps on her skin.
She reached for the balloon again, brought it to her chest. Pressed it against her sternum, the latex cool and smooth. She closed her eyes and imagined his hands there instead. His palms, warm and trembling, pressing against her skin.
Her hand slid lower, over her stomach, to the waistband of her shorts. She hesitated, her fingers resting on the button. Through the wall, she heard him shift. A creak of his bedsprings. A soft exhale.
She undid the button. Slid her hand inside.
She was already wet. She'd been wet since she'd seen him standing in his doorway, the balloon clutched in his fist, his ears burning red. She'd been wet since he'd whispered her name back through the wall.
She pressed the balloon against her mouth, muffling the sound of her own breath as her fingers found her clit. She was slick, ready, aching. She circled slowly, her hips lifting off the bed, the balloon pressed tight against her lips.
She imagined him on the other side of the wall, doing the same thing. His hand wrapped around his cock, his eyes closed, his mouth open. Imagined him thinking of her. Imagined him coming undone because of her.
Her fingers moved faster. Her breath came in short, sharp gasps, muffled by the latex. The balloon vibrated against her lips with every sound she made.
She was close. So close. She could feel it building, a pressure low in her belly, a heat spreading through her thighs.
She bit down on the balloon. Hard.
It didn't pop. But the pressure, the resistance, the feel of latex between her teeth—it pushed her over the edge. She came with a shudder, her back arching off the bed, her fingers pressing hard against her clit as the wave rolled through her.
She lay there, panting, the balloon still pressed to her mouth. Her hand was wet. Her shorts were damp. Her whole body was trembling.
Through the wall, she heard him exhale. Long. Slow. Shuddering.
Her heart stopped. Then started again, faster.
He'd heard her. He must have. The walls were paper thin, and she hadn't been quiet. She'd tried to muffle herself, but the bedsprings, the breath, the wet sounds—he'd heard it all.
She smiled, slow and satisfied, and pressed the balloon to her lips one more time.
Good.
She wanted him to know. She wanted him to lie there, hard and aching, knowing exactly what she'd been doing. Knowing she'd been thinking of him.
She set the balloon aside and pulled her shorts off, tossing them onto the floor. She'd deal with them in the morning. For now, she lay naked in the dark, her skin still flushed, her heart still racing, and listened to him breathe through the wall.
She wondered if he'd knock tomorrow. She wondered if he'd have the courage to look her in the eye after tonight. She wondered if he'd be holding another balloon.
She hoped so.
She rolled onto her side, facing the wall, and pressed her palm flat against it. The surface was warm. She imagined his hand on the other side, matching hers, finger for finger.
"See you tomorrow, Liam," she whispered.
There was a pause. A breath. Then, soft and rough, through the wall:
"See you tomorrow."
She closed her eyes, still smiling, and let the sound of his voice carry her into sleep.
