By evening Koo had finished packing and drove straight to Taehyung’s apartment building with a big excited smile. She had stalked him quietly over the past few days (of course she knew exactly where he lived), but she would never admit that. She rang the doorbell, heart racing, her tiny dress already riding up her thick thighs.

The door opened. Taehyung stood there shirtless in grey sweatpants, muscles glistening, looking stunned.

“Koo?! How the fuck are you here? I never gave you my address,” he growled, eyes narrowing.

She blinked up at him with big innocent eyes, biting her pink lip. “One of the firemen told me, Tae~ He felt bad that my kitchen got ruined. Can I come in now? Pleeease?”

She didn’t wait for an answer, slipping past him. Her fat ass brushed against his crotch as she entered. The apartment was clean, masculine, and smelled like him. Koo’s pussy throbbed.

“Cute place, Daddy,” she purred. “Can you bring my things from the car please? Pretty please?” Before he could reply she tossed her car keys at him. He caught them effortlessly, jaw clenched in irritation.

“You’ve got to be kidding me…” he muttered, but went downstairs anyway. When he opened her car trunk, he froze. There were multiple huge suitcases, bags, and boxes — like she was moving in for good.

He carried everything up in trips, muscles flexing. Koo waited inside, watching him with hungry eyes.

“So much stuff for a few weeks?” he asked, dropping the last bag with a thud.

Koo smiled sweetly and stepped close, pressing her big soft tits against his chest. “A girl needs options, Tae… Especially when she wants to look pretty for her favorite firefighter.”

She batted her lashes. “So… can I sleep in your room with you? I get scared at night~”

Taehyung growled low, cock already twitching. “No. Guest room. Now.”

He showed her the spare room. Koo pouted dramatically, pushing her lower lip out. “But your bed is bigger… and warmer. Fineee.”

She spent the next hour “settling in,” humming happily while unpacking her sluttiest lingerie and tiny clothes right where he could see when he passed by.

Later that night, the smell of dinner filled the apartment. Taehyung was cooking shirtless in the kitchen when Koo came out. She wore the tiniest white babydoll dress — basically see-through, no bra, no panties. Her big heavy tits bounced freely with every step, dark pink nipples hard and visible. The hem barely covered the bottom of her fat ass.

“Smells so good, Tae~” she moaned, coming up behind him and pressing her soft body against his back. “You’re so strong and domestic… makes a girl wet.”

She bent over the counter right next to him to “look” at the food, ass up, skirt riding up completely. Her pink fat pussy and tight little asshole flashed him openly. Taehyung’s cock surged in his sweatpants.

“Fuck, Koo… cover yourself,” he hissed.

“Oops~” she giggled, but made no effort to pull the dress down. “It’s so hot in here. Don’t you think?”

During dinner she sat across from him, moaning loudly with every bite like she was sucking cock.

“Mmmhh~ So thick and juicy… fills my mouth so well,” she whimpered, sucking noodles off her chopsticks obscenely, lips wrapped tight, cheeks hollowing. “I love swallowing big loads… I mean, big portions.”

Her big tits rested on the table, nipples poking against the thin fabric. She kept “accidentally” dropping her spoon and bending down low to pick it up, flashing her dripping pink pussy again and again.

Taehyung’s cock was rock hard the entire meal, tenting his sweatpants obviously. He scoffed internally. Of course she’s such a slut. Like mother like daughter. Mimi was exactly the same — cock-hungry whore.

“You’re doing this on purpose,” he growled.

Koo licked her lips slowly. “Doing what, Daddy? I’m just enjoying the meal you made for me. Maybe later I can enjoy something even bigger and thicker down my throat…”

After dinner they washed dishes together. She kept brushing her ass against his crotch “by accident” and whispering filthy things.

“Your hands are so big… I bet they’d feel amazing spreading my fat pussy open.”

Taehyung stayed silent, irritated but painfully hard. They finally went to their separate rooms.

A few hours later, deep in the night, Taehyung stirred. Something warm and soft was pressed against him. He opened his eyes and stiffened — Koo was in his bed, curled up against his side in that same tiny dress, one thick thigh thrown over his leg. Her bare pussy was dangerously close to his thigh.

“What the—?” He slapped her fat ass hard, the sound echoing.

Koo gasped awake, moaning softly at the sting. “Ahh~ Tae!”

“Why the fuck are you in my bed?” he demanded, voice rough.

She pouted, looking sleepy and innocent. “I must have sleepwalked… I do that sometimes when I’m stressed~”

“Bullshit. What a slut,” he scoffed.

Koo’s pout deepened but she slowly got up, deliberately grinding her wet pussy along his thigh and brushing her big tits across his chest as she moved. “Sorry, Daddy… I’ll go back to my cold lonely room.”

She walked out slowly, ass swaying.

Taehyung lay there with his cock painfully hard, throbbing against his stomach. He couldn’t take it anymore. He got up and went to the bathroom, turning on the cold shower. But even the cold water didn’t help. He wrapped his big hand around his thick, veiny cock and started stroking hard, eyes closed, picturing Koo’s pink fat pussy and bouncing tits.

“Fuck… Koo… you little slut,” he groaned, pumping faster. “That tight cunt… bending over like a whore…”

His strokes got sloppy and desperate. “Gonna fuck that fat pussy… shit— Koo!” He came hard with a deep moan, thick ropes of cum shooting against the shower wall as he pictured filling her up.

Panting, he leaned against the tiles, knowing deep down this was only the beginning.
