Sofia did not let go of the balloon. She turned it in her hands, slow, the dusty-rose rubber creaking under her palms, and watched the dust lift off the latex in the low amber light — fine gray powder catching in the stove hood's beam, drifting, settling on her knuckles. The knot Hazel had taught her to tie sat fat and tight at the neck, a small bead of rubber that held the whole soft body of it in place.

The kitchen smelled of warm bread and the damp earth still coming off Ivy's sweater, which hung over the back of a chair by the table, sleeves trailing. Hazel had not stepped back. She stood close enough that Sofia could see the freckles scattered across her collarbones, the flush already climbing her neck, the way her breath had not quite evened out from the hug.

Sofia looked up at her. "Show me what you do when you're alone."

It was not a dare. She said it the way she asked for things that mattered — flat, direct, no room in it for a no. The refrigerator hummed. Somewhere upstairs a floorboard took Ivy's weight and let it go.

Hazel's breath caught. Sofia heard it — a small, sharp thing at the back of her throat, the sound of a door being knocked on from the wrong side. Her hands went still around the balloon. For a moment Sofia thought she would laugh it off, or hand it back, or say it's late, go to bed.

Then Hazel reached out and took the balloon.

Her fingers found the neck the way they always did — practiced, unhurried, the same grip she had used to guide Sofia's hands through the knot. She did not look at Sofia while she did it. She looked at the balloon, at the dusty-rose skin of it, at the faint print of Sofia's fingers still pressed into the latex where she had held it too hard.

"It's not the pop," Hazel said. Her voice came out rough, scraped low, a register Sofia had never heard from her in daylight. "Everyone thinks it's the pop. It's not."

She brought the balloon up against her own chest first, both hands cradling it, pressing it flat until the rubber went taut and warm between her palms. Sofia watched her exhale — a long, slow breath that seemed to come from somewhere below her ribs. The balloon gave a soft, hollow creak as it took her weight.

"It's the sound of it holding you," Hazel said.

"Holding you how."

"Like it won't let go." Hazel's thumbs pressed the latex in, dimpling it. "Like it's got you. You can lean all your weight on it and it just — takes it. It doesn't ask you to be careful."

She moved it down. Past her waist, past the hem of the chunky knit she was wearing, until the balloon rested against her belly, then lower — against the front of her leggings, against the soft heat of her, and she pressed it there with the flat of her hand and let her hips shift forward into it. The latex sighed. It was a wet sound, a small, close sound, and Sofia felt it in the backs of her knees.

"Hazel."

"You asked."

"I know what I asked. I'm asking again."

Hazel did not look up. She dragged the balloon down her inner thigh, slow, deliberate, and the dust that had been on the latex came off against the cotton of her leggings in a pale smear. She pressed it into the crease of her thigh and her cunt through the fabric and ground down against it, once, and the sound that came out of her mouth was not a word. It was a low, wet, involuntary thing — a moan she tried to swallow and could not, and Sofia watched her sister's eyes go half-lidded and dark in the amber light.

"There," Hazel breathed. "Right there. That's — that's the spot, that's the whole thing, right there —"

"Show me the whole thing, then. Don't stop at the good part."

The stove hood flickered. The bulb buzzed once and steadied.

Sofia's hand moved before she decided to move it. She laid her palm over Hazel's — over the back of the hand pressing the balloon into the front of Hazel's leggings — and felt the rhythm underneath. Hazel was not grinding hard. She was grinding slow, a long, patient roll of her hips, and the balloon took every inch of it, bowing inward and springing back, bowing and springing, the rubber creaking against the cotton with each pass.

"That's it," Sofia said. She did not know she was going to say it. "That's — that's what it is."

"Say it again."

"That's it."

"Again."

"That's it, Hazel. That's it."

Hazel's hips stuttered. Her free hand came up and closed around Sofia's wrist, not to move it, not to push it away — just to hold it there, to keep Sofia's palm flat over the back of her hand while she rolled into the balloon again, deeper this time, and the wet squeak of latex against cotton filled the small kitchen like something being said out loud for the first time.

"Don't laugh," Hazel whispered.

"I'm not laughing."

"I know. I know you're not." Hazel's voice cracked at the edge. "I just — I have to say it, because if I don't say it I'll think it, and if I think it I'll stop, and I don't want to stop, so. Don't laugh."

"I won't. Keep going. Keep going, I've got you."

Sofia pressed down on her hand. Hazel made a sound like she had been holding it for years and had finally been given permission to put it down. Her hips picked up — not faster, but harder, driving the balloon flat against her cunt through the leggings, and Sofia could feel it through the back of Hazel's hand, the way the whole soft weight of her pressed into the rubber and the rubber pressed back, the way her breath came apart into pieces, the way the flush had reached the tips of her ears and the hollow of her throat.

"It's the sound," Hazel said again, barely. "It's the sound of it — not breaking. It holds. It just holds you, and it doesn't — it doesn't go anywhere, it doesn't leave, it just —"

"It stays."

"It stays."

"Then stay with it. Don't fight it. Let it hold you."

"Sofia —"

"I'm right here. I'm not going anywhere either."

She came with her hand under Sofia's hand and the balloon crushed flat against her and her forehead dropping onto Sofia's shoulder. Her breath went ragged, all the way ragged, and stayed there. The balloon gave one long, low, groaning creak as she rolled through it, and then she was still, and her weight was warm and heavy against Sofia's chest, and her hand was still wrapped around Sofia's wrist, holding it there, holding it in place.

"Oh," Hazel said, into Sofia's shoulder. Just that. "Oh."

The kitchen was quiet except for the refrigerator and the tick of the stove hood's bulb cooling. The bread smell had gone stale at the edges. Sofia could feel Hazel's heartbeat through the back of her hand, fast and then slowing, fast and then slowing, and she did not move her hand, and Hazel did not let go of her wrist.

"Okay," Sofia said, into Hazel's hair. "Okay."

"Okay," Hazel said back. Her voice had gone soft and used-up, the way a voice goes after it's been somewhere.

Hazel laughed — a wet, broken, relieved little laugh — and lifted her head. Her eyes were bright and wet and she did not wipe them. The balloon was still pinned between her hand and her body, deflating slightly now, the latex gone soft and slack against her leggings.

"That's what I do," she said. "When I'm alone. That's — that's all of it. That's the whole thing."

"Is that all of it?"

"That's all of it. That's the whole thing, I swear."

Sofia looked at the balloon, then at Hazel's face, then at her own hand still pressed over Hazel's. "It's not nothing," she said. "You know that, right? It's not nothing."

"I know."

"Because it's the same thing. What you just did — it's the same thing I did. With Emmy. It's the same."

Hazel's mouth opened, then closed. She looked at Sofia for a long moment, and something moved behind her eyes — not shock, exactly. Recognition. The look of a person who has spent years believing their thing was a lonely thing, and has just been told, in a kitchen, by my sister, that it is not.

"Yeah," Hazel said finally. "It's the same."

"Then say it."

"It's the same." Hazel's chin lifted. "It's the same thing."

Behind them, the kitchen door creaked.

Emilia came in barefoot, hair sleep-mussed, one of her enormous grey sweatpants legs dragging on the tile. She did not stop at the threshold. She walked straight to Sofia and wrapped her arms around her from behind, chin settling onto Sofia's collarbone, cheek against Sofia's cheek. Her breath was warm and slow. She had clearly been standing in the hallway for a while.

"Hi," Emilia said.

"Hi," Sofia said. Her hand was still on Hazel's. She did not move it.

"How long were you out there?"

"A while." Emilia's arms tightened. "I heard the creaking."

Emilia turned her head and kissed Sofia — lightly, on the mouth, the way she did now, the way that was no longer a question. Sofia kissed her back. It was short and soft and it happened in front of Hazel, in the amber light, with the balloon still pinned between Hazel's hand and her body, and Hazel watched them do it with her breath held and her eyes wide and did not say a word.

Emilia pulled back. She looked at Hazel, then at the balloon, then at Sofia's hand covering Hazel's hand. She did not ask what she had walked into. She took Sofia's free hand and tugged.

"Come to bed," Emilia said. "I want to show you something."

"Hazel."

"Go on." Hazel's voice came out steady, which surprised even her. "Go with her. I'm okay."

"You're sure."

"I'm sure. Go."

Sofia looked at Hazel. Hazel nodded — small, quick, a permission and a dismissal at once — and let go of Sofia's wrist. Her hand stayed on the balloon. Sofia's hand stayed on hers for one more beat, feeling the last of the heat through the latex, and then she pulled it away and let Emilia lead her out of the kitchen.

At the doorway, Sofia looked back. Hazel was still standing in the stove hood's light, the dusty-rose balloon hanging slack from her hand, her leggings dark at the front, her face open in a way Sofia had never seen it — not ashamed, not hidden, just seen. Hazel lifted the balloon a little, an offering or a salute, and Sofia lifted her chin in answer.

Then Emilia pulled her into the hall, and the kitchen door swung shut behind them, and the light under it went dark.

Hazel stood alone for a moment. Then she turned toward the bedroom, and Ivy was leaning in the bedroom doorway with her arms crossed and a slow, knowing smile, and Hazel walked toward her with the balloon still in her hand.

"How long were you standing there?" Hazel asked.

"Long enough," Ivy said. She reached out and caught the balloon's neck between two fingers, and tugged Hazel in by it, gently, the way you lead a horse by the halter. "Come here. Tell me what you taught her."

"You first. How long is long enough."

"Since the creaking. Since before the creaking." Ivy's fingers tightened on the rubber. "Come here, Hazel. Don't make me ask twice."

Hazel let herself be pulled. The balloon came with her, its neck pinched between Ivy's two fingers, the fat body of it dragging against Hazel's thigh as she stepped into the bedroom doorway. Ivy did not let go. She backed into the room a half step at a time, reeling Hazel in by the rubber, and the latex stretched and whitened at the neck under the pull, and Hazel felt the tug all the way down between her legs, a low, answering pull, like something on a string.

"She asked me to show her," Hazel said. Her voice was still scraped low. "She stood there and she asked me to show her what I do when I'm alone. And I did."

"I heard."

"You heard."

"The creak," Ivy said. She let the balloon's neck slip through her fingers an inch, then caught it again. "And the other sound. The one you don't make for me." She said it without edge — a plain observation, laid down between them like a card face-up. "I came in through the front and I heard it before I saw you. I stood in the hall and I listened to the whole thing."

"And you just stood there."

"I just stood there."

"Ivy —"

"I'm not angry." Ivy's thumb rolled the knot of the balloon against her knuckle. "I'm standing here holding the thing you came on, and I'm telling you I heard it. That's all. That's the whole of it."

Hazel's face went hot. The flush that had only just begun to fade from her ears came back, all at once, and she looked down at the balloon instead of at Ivy's face. The latex was dull where Sofia's hands had held it, the dust smeared into a cloudy thumbprint near the neck.

"You're not —" she started.

"I'm not anything," Ivy said. She reached up and tucked a strand of Hazel's hair back behind her ear, and her fingers were cool against the heat of Hazel's cheek. "I'm standing in a doorway looking at you, and you're holding a balloon that's been against your cunt, and you're telling me you showed your sister how you come. I'm not anything. I'm just here."

"Say what you're actually thinking."

"I'm thinking you're beautiful when you don't hide." Ivy drew the balloon in another inch. "I'm thinking I want to hear you do it again. For me, this time."

The stove hood light in the kitchen behind them flickered once more — a brief brown-out, a buzz, and then the steady amber again, spilling a thin blade of it under the bedroom door and across the floorboards between Ivy's bare feet. Hazel watched the light move. Somewhere deeper in the flat, a door clicked shut, and then another, and then the low murmur of two voices — Emilia's and Sofia's — threaded through the wall like water finding a seam.

"She's not a child," Hazel said. "Not in that room. I don't know what she is, but she's not —"

"I know." Ivy's thumb moved along the balloon's neck, slow, working the rubber against itself. "I've known since the milk. I've been waiting for you to know it too."

Hazel looked up. Ivy's glasses had slid down her nose, and she pushed them back with her knuckle, and the gesture was so ordinary, so completely Ivy, that Hazel felt her chest go tight with something that was not quite want and not quite grief. Two years of the same face across a breakfast table. Two years of the same hands adjusting the same glasses. And now those hands were holding the balloon she had just come against, and not one line of Ivy's face had changed.

"Tell me what you taught her," Ivy said again. "Not the balloon. The other thing. What did you tell her about it."

Hazel thought about it. The kitchen, the amber light, Sofia's palm flat over the back of her hand. It's not nothing. She had spent years certain that the thing she did alone in the dark was the most private thing a person could do, and my sister had stood in the middle of it and said it's the same thing I did, and the floor had not opened.

"I told her it holds you," Hazel said. "That's all. That it doesn't leave. That it just — stays, and takes it, and doesn't go anywhere."

Ivy was quiet for a moment. Then she drew Hazel in the last of the way, by the balloon, until they were close enough that Hazel could smell the cold air on her sweater and the tea on her breath, and she let the balloon go slack between them, and it hung there, a soft dusty-rose weight, pressed flat between Ivy's hip and Hazel's.

"Show me," Ivy said. "Not the way you showed her. The way you do it when there's no one to explain it to."

Hazel's breath caught — the same small, sharp catch from the kitchen, the same knocked-on door — and this time she did not swallow it. She took the balloon back from Ivy's fingers, found the neck with the same practiced grip, and turned it in her hands once, watching the dust lift again in the thin amber light under the door.
