Within a week, Jungkook had slipped into the rhythms of the household.

He was surprisingly good with Minho — every morning, the boy would come knocking on his grandfather's door, pulling him outside to play catch or chase in the yard. His laughter was bright and warm, the way only a child's could be, and even Siwon admitted he was grateful for the extra help.

Jungkook even helped with small chores: fixing a leaky faucet, carrying in groceries, trimming the garden. At times, it almost felt normal. A family of four.

But normal cracked whenever Tae was near.

She was always dressed the way she liked - tight shorts, crop tops that showed the curve of her breasts, skirts that ended halfway up her thighs. She didn't mean to provoke him... or maybe she did, just a little. The way his eyes darkened whenever she passed made something coil tight inside her belly.

One afternoon, she was alone in the kitchen rinsing fruit when she felt a presence behind her. Warm breath tickled her ear.

"Taeri.."

Her spine stiffened. She didn't turn.

"It's Taehyung, Dad," she whispered.

But Jungkook's hand slid along her waist, rough fingers pressing into the thin fabric of her tank top. "You'll always be my Tae. My wife." His voice was low, hoarse, thick with hunger.

Her breath caught when his hand crept higher, brushing just beneath the swell of her breast.

"W-what are you doing?" she murmured, glancing nervously toward the doorway. Minho and Siwon were outside in the garden. Still-this was wrong.

But Jungkook pressed closer, his chest against her back. "You used to wear this... little shirt. Just like this. No bra underneath.

You'd lean over the counter and l'd take you right there." His words were hot against her skin, filth pouring straight into her ear.

Her knees weakened.

"Dad-" she tried again, but it came out more like a gasp.

His hand cupped her breast fully now, thumb brushing across her nipple through the fabric.

The wet fruit in her hands slipped back into the sink.

"You drove me mad, Tae," he whispered, teeth grazing her ear. "Always teasing me, always showing me those tits... you wanted me hard all the time."

Her chest heaved, breath ragged. She should've pushed him away. But instead she stayed still, frozen in the sinful warmth of his touch.

Later that night, as Siwon sat on the couch with Minho tucked against him, Jungkook walked past where Tae was bending to pick up a toy. His hand lingered on her ass, squeezing firmly before moving on as if nothing happened.

Her cheeks burned, but she didn't say a word.

The days blurred, and the touches became more frequent. A brush of his hand on her thigh when they sat too close. Fingers trailing down her back when she passed. Sometimes he whispered things that made her thighs press together in shameful heat:

"Your pussy was always so sweet, Tae."

"God, I missed the way you moaned when I split you open."

"You were made to be fucked."

Each time, she reminded him she was his daughter. Each time, his cloudy eyes filled with confusion, then desire, then need. And each time, her own body betrayed her with a pulse between her legs.

It wasn't just him anymore. She was starting to feel it too.

One evening, while Siwon bathed Minho upstairs, Jungkook cornered her in the hallway. His hand slammed gently against the wall beside her head.

"You can't keep pretending you don't want it," he growled, his lips brushing her ear.

Her chest rose and fell rapidly, nipples straining against the thin silk of her camisole.

"Dad... please.."
