The air conditioner hummed too loud, but not loud enough to drown out the silence between them. Koo shifted under the sheets, her thigh brushing against Minsoo's—warm, familiar, and somehow heavier tonight.

"You tired?" she asked, tracing circles on his chest. Her nails were painted pink, chipped at the edges from last week's grocery runs.

Minsoo exhaled, slow. "Just thinking." His fingers twitched against her hip, like he wanted to pull her closer but didn’t.

Koo rolled onto him, straddling his waist while the sheets pooled around them. She ground down, bare skin sliding against his. "Think later," she murmured, leaning to catch his lips.

He kissed her back, lazy and deep, but when her hand dipped between them, his body didn’t respond the way it used to. She squeezed him anyway, pumping slow, waiting—hoping—for the heat to bloom under her palms. It never came.

"Baby," she whispered against his mouth, pressing his hand between her legs. "Feel how wet I am."

Minsoo groaned, but it sounded more like frustration than want. His fingers moved, rubbing clumsy circles like he was trying to remember how she liked it.

Koo rocked against him, breath hitching. "Just fuck me," she pleaded, guiding him inside her.

It didn’t work. He slipped out almost immediately, soft and useless between her thighs.

Her breath caught differently then—sharp, wounded. "Am I not tight enough anymore?" Her voice cracked. "Or do you not—"

Minsoo gripped her waist, hauling her flush against him. "No," he said fiercely. "You’re perfect." He thrust up weakly, still half-hard at best. "It’s me."

Koo buried her face in his neck, lips trembling against his skin.

"Talk to me," she whispered.

Minsoo hesitated, then rolled her onto her back, pinning her wrists. "I wanna try something different." His thumbs traced her pulse—fast, uneven.

Her brows knitted. "Like... what?"

His exhale was hot against her collarbone. "I want to watch," he said slowly, "other men fucking you."

Koo's breath hitched. The room suddenly felt ten degrees hotter. "W-what?"

"Men who can give you what I can't right now." His grip tightened—not painful, just possessive. "Strong ones. Hands all over you."

A whimper slipped out before she could stop it. Heat pooled violently between her legs, dripping onto Minsoo's thigh.

He chuckled darkly, dragging a finger through the slickness. "Look at you," he murmured. "My slutty wife getting wet at the thought."

Koo arched against him, thighs clamping around his hips. "Say it again," she begged.

"Which part?" He pressed his hardening cock against her soaked folds. "That you're a greedy little slut? That I'm gonna sit back and watch you take cock after cock—"

She came with a sob, nails raking down his back.

Minsoo growled, finally fully hard, slamming into her with a force that made the headboard crack against the wall. "Fuck," he gritted out, "you're clenching so tight just imagining it, aren't you?"

"Yes!" Koo clawed at his shoulders, heels digging into his ass. "More—"

He pistoned into her, each thrust punctuated with filthy praise. "Gonna pick them out together," he promised. "Big, thick cocks to stretch you wide—"

Her scream muffled against his shoulder as she shattered again. Minsoo followed, biting her neck as he spilled inside her, both trembling.

Silence. Just their ragged breathing.

Then Koo, voice small: "...Really?"

Minsoo kissed her swollen lips. "Really." His thumb swiped at her tears—she hadn't even realized she'd cried. "But only if you want—"

She kissed him hard. The answer was obvious.

"I want you to pick," she whispered against his mouth, her body still trembling from the aftershocks of her orgasm. "Big ones—like you said." Her fingers trailed down his chest, nails digging lightly. "Strong enough to make you jealous."

Minsoo groaned, flipping her onto her stomach in one rough motion. His hand tangled in her pink hair, yanking her head back as he slammed into her from behind. "Fuck," he gritted out, the slap of skin echoing. "You’re already planning it, aren’t you? My little whore."

Koo’s moan was loud, unashamed. "Yes—yes—" She arched her back, pushing her ass against him. "Want them to—ah!—see how tight I am for you."

He fucked her harder, hips snapping. "They won’t last two minutes," he growled. "Not when you clench like this."

Her laughter was breathless, broken by pleasure. "Then—hnng—find ones who can."

Minsoo’s rhythm stuttered. The thought alone tightened his grip on her hips hard enough to bruise. "Christ," he hissed. "You’re serious."

Koo turned her head just enough to catch his lips again, slow and filthy, before murmuring, "Dead serious." Her hand slid between her legs, rubbing tight circles as he drove into her. "Imagine it—their hands on me, their cocks in me—" She gasped as her own fingers pushed her over the edge again, her walls pulsing around him.

Minsoo swore, coming so hard his vision whited out. When he could breathe again, he collapsed beside her, dragging her limp body against his chest. "We’re really doing this," he said—not a question.

Koo traced the sweat-slick planes of his abs, grinning when his muscles twitched under her touch. "Mm. Starting tomorrow?"

His chuckle was dark. "Eager."
