The university courtyard buzzed with the usual afternoon chaos—students laughing in clusters, coffee cups steaming, the faint scent of street food from vendors nearby. Tae clutched her sketchbook to her chest like a shield, her white skin glowing under the dappled sunlight filtering through the trees. She was dressed in her typical slutty flair: a tight pink halter top that tied behind her neck, leaving her shoulders bare and her massive tits pushed up into a deep cleavage that jiggled with every step. Paired with it was a denim mini-skirt so short it barely skimmed the bottom of her plump ass cheeks, her thick thighs rubbing together as she walked, sending little sparks of friction straight to her pink, fat pussy nestled in lacy black panties.

She’d been hoping to catch a glimpse of Namjoon today. Maybe bump into him “accidentally” near the art building, flash him one of her shy smiles, feel that flutter in her chest when he said her name. But as she turned the corner, the whispers hit her first.

“Did you hear? Namjoon’s totally into Sana unnie. They’ve been hanging out non-stop.”

Tae froze, heart dropping like a stone. Sana—the stunning senior with the long legs and confident laugh, always in those chic outfits that screamed sophistication. The kind of girl who knew how to flirt without blushing.

No. It couldn’t be.

But then she saw them. Namjoon leaning against a bench, his dimpled smile wide as Sana touched his arm, tossing her hair back with a giggle. He looked… happy. Engaged. Not like the distant, professional senior who critiqued her paintings.

Tae’s pink lips parted in shock, her big eyes stinging with unshed tears. Anger bubbled up hot and unexpected—how dare Sana? How dare Namjoon not notice her? She’d been crushing so hard, imagining his hands on her canvas, on her body. And now this?

She spun on her heel and bolted, sketchbook forgotten under her arm, tears blurring her vision as she raced home.

By the time she slammed the front door behind her, her face was a mess—mascara streaked, cheeks flushed red, lower lip trembling. Dohyun and Jihyo were in the living room, chatting with Jungkook, who was lounging on the couch like he belonged there. A bottle of whiskey sat half-empty on the coffee table; it was one of those casual evenings where Kook dropped by unannounced.

“Tae-yah?” Jihyo stood up, concern etching her pretty features. “Baby, what’s wrong? You look—”

“Nothing, Eomma,” Tae mumbled, voice cracking. She tried to dart past them toward the stairs, but Jungkook’s sharp eyes caught everything. The way her shoulders hunched, the quiver in her plump lips, the way her tits heaved with shaky breaths.

He set his glass down, standing smoothly. “Hey, princess. Rough day?”

She ignored him, feet pounding up the stairs.

Dohyun frowned. “Maybe I should—”

“Let me,” Jungkook said, voice casual but firm. “You two finish that story you were telling. I’ll check on her. Uncle Kook’s got this.”

Jihyo hesitated but nodded. “You’re good with her, Kook-ah. Thanks.”

He flashed them a reassuring smile and followed her up, his long strides eating the distance. By the time he reached her bedroom door, it was cracked open. He pushed inside without knocking, closing it softly behind him.

Tae was curled on her bed, face buried in a pillow, her skirt hiked up enough to show the curve of her ass and the black lace peeking between her thighs. She hadn’t heard him—or if she had, she didn’t care.

Jungkook leaned against the door, crossing his arms over his broad chest. God, she looked edible like that. Vulnerable. Ripe.

“Alright, little slut,” he drawled, voice teasing as always. “What’s got you all worked up? Did some boy at school forget to stare at your tits long enough?”

Tae’s head snapped up, eyes wide and glistening. For a second, she just stared at him, lips parting like she might snap back. Then her face crumpled, and she burst into tears—big, heaving sobs that shook her whole body, her massive boobs bouncing with each gasp.

Jungkook’s smirk vanished. Panic flickered in his dark eyes. Shit. He wasn’t used to this. Teasing her, yeah. Making her squirm and blush, absolutely. But actual tears? From his princess?

“Hey, hey,” he said, crossing the room in two strides. He sat on the edge of the bed and pulled her into his arms without thinking. “Come here, baby. Shh, it’s okay.”

Tae didn’t resist. She melted into him, burying her face in his chest, her soft, heaving tits squishing against his hard muscles through the thin fabric of her top and his shirt. The contact was electric—her nipples hardening instantly against him, the plush weight of her breasts molding to his body like they were made for it.

Jungkook’s breath hitched. Fuck. But he focused, wrapping his strong arms around her. One hand stroked her back soothingly; the other slid lower, cupping the full globe of her ass cheek, squeezing gently as he caressed it in slow circles. “There, princess. Uncle Kook’s got you. Let it out.”

She cried harder at first, soaking his shirt, but his touch—firm, possessive—started to calm her. The way his palm kneaded her ass, fingers dipping just under the hem of her skirt to graze bare skin, sent conflicting shivers through her. Comfort and heat twisting together.

After a few minutes, her sobs turned to sniffles. She pulled back slightly, but he didn’t let her go far, keeping her close.

“What’s wrong, Tae?” he murmured, thumb brushing a tear from her cheek. His voice was softer than usual, but his eyes burned with that familiar lust. “Tell me. Who made my pretty girl cry?”

Tae bit her lip, looking away. Her pink pussy throbbed faintly from the ass caress, but she ignored it. “It’s… stupid.”

“Nothing’s stupid if it hurts you like this.” He tilted her chin up, forcing her to meet his gaze. “Talk to me.”

She hesitated, then it spilled out. “There’s this guy… Namjoon. My senior in arts. I’ve had a crush on him forever. But today I heard rumors he likes someone else—Sana unnie. And I saw them together. Laughing. Touching. I just… I thought maybe he could like me back, but why would he? She’s perfect, and I’m just…”

Jungkook’s jaw tightened. Inside, rage boiled—hot, possessive fury. Namjoon? Some fucking college kid? No way in hell was he letting that happen. Tae was his. Had been since she turned eighteen, her body filling out into this perfect, fuckable dream. He’d waited, bided his time, watching her parade around in those slutty clothes, teasing him without knowing. And now some boy threatened to take what was rightfully his?

But on the outside, he stayed calm. A smirk curved his lips as an idea sparked—dark, delicious. Oh, this was perfect.

He pulled her closer, shifting so he was fully on the bed, back against the headboard. “Come here, princess. Sit properly so I can hold you right.”

Tae blinked, still sniffly, but let him guide her. He maneuvered her until she was straddling his lap, her thick thighs spread wide over his hips, her fat ass settling right on his crotch. The position hiked her skirt up completely, her lace-covered pussy pressing against the growing bulge in his slacks.

She gasped softly, feeling the heat of him through the fabric. “U-Uncle Kook…”

“Shh,” he soothed, hands on her hips, holding her there. “Just like this. Feels better, doesn’t it? Now listen to me.”

Tae nodded shyly, her big tits inches from his face, nipples poking through the halter top. Her cheeks burned, but the closeness was… comforting? Or something more. She could feel her pussy getting damp, the plump lips swelling against her panties.

Jungkook looked up at her, eyes dark with intent. “You’re beautiful, Tae. Fuck, you’re the most gorgeous thing I’ve ever seen. Those pink lips, that white skin that flushes so pretty, these big, soft tits that make every man hard just looking at them.” His hands slid up her sides, thumbs brushing the undersides of her breasts. “And this ass… god, princess, it’s so juicy, so perfect for grabbing.”

Tae squirmed, breath hitching. “S-stop… that’s embarrassing.”

“It’s true,” he growled softly. “Any guy would be lucky to have you. Namjoon? He’d be a fool not to want you. But if he’s blind, we can fix that.”

Her eyes lit up through the tears. “R-really? How?”

Jungkook’s smirk deepened. “I can help you win him over. Teach you everything.”

“Teach me?” She tilted her head, innocent confusion in her big eyes.

“Yeah, baby.” His voice dropped to a husky whisper. “How to seduce a man. How to make him crave you. How to satisfy him so good he forgets every other girl exists.”

Tae’s face turned scarlet, but excitement sparked in her chest. “You… you would do that? For me?”

“Of course, princess.” Inside, his mind raced with filthy plans. Oh, I’ll teach her alright. Teach her how to take my cock, how to beg for it, how to cum screaming my name. Make her so addicted she’ll never look at that boy again. She’s mine. No one else’s. Not while I’m breathing.

He nodded, hands squeezing her hips. “We’ll start slow. But you have to trust me. Do what I say.”

Tae bit her lip, nodding eagerly. “Okay. I trust you, Uncle Kook.”

That’s when she felt it—his cock, rock-hard now, throbbing under her fat ass. The thick length pressed right against her crack through their clothes, hot and insistent.

She stiffened, eyes widening. “U-Uncle Kook… you’re… hard.”

He chuckled darkly, not even pretending to be sorry. “Can you blame me? With this perfect ass on my lap, your tits in my face? You’re a walking wet dream, Tae.”

She flushed deeper, trying to shift away, but he held her firm. “W-we shouldn’t—”

“Shh.” He started grinding—slow at first, rolling his hips up so his bulge dragged against her lace-covered pussy and ass. The friction made her gasp, her plump lips parting. “This is lesson one, princess. Feel how a man reacts to you. How hard you make me.”

Tae’s breath came in pants, her pussy soaking through her panties now, the fat folds slick and aching. “B-but… oh god… it’s so big…”

“Yeah? You like that?” He ground harder, the head of his cock nudging her clit through the fabric. His hands slid down to squeeze her ass cheeks, spreading them slightly as he thrust up. “Imagine what it’ll feel like inside you. Stretching that tight little pink pussy wide.”

She whimpered, hands clutching his shoulders. “Uncle Kook… this is wrong… but it feels… ah!”

“Wrong? Nah, baby. This is what I’ll teach you.” He squeezed harder, fingers digging into her soft flesh. “How to grind on a man’s cock like a good slut. How to bounce on it until he cums buckets. How to suck dick—deepthroat it, swallow every drop while looking up with those big eyes.”

Tae’s head fell back, moans escaping despite herself. Her hips started moving on their own, rocking against him, her wet pussy leaving a damp spot on his slacks. “T-teach me… please… I want to make Namjoon feel like this…”

Jungkook’s eyes flashed with jealousy, but he hid it. “Oh, I’ll teach you more than that. How to beg for a cock in your ass—stretch that tight hole until it takes every inch. How to play with your tits while riding, pinching those hard nipples until you squirt.”

She gasped, grinding faster. “S-squirt? I… I’ve never…”

“You will, princess.” He thrust up sharply, making her bounce. “I’ll finger that fat pussy until you soak the sheets. Teach you to take two fingers, three, then my whole fist if you’re a good girl. Make you cum so hard you forget your own name.”

Tae was lost now, her shy demeanor cracking under the heat. “Uncle Kook… your cock feels so good… rubbing my pussy… ah, harder!”

“Fuck, yeah,” he groaned, hands kneading her ass roughly. “Grind that sloppy cunt on me. Get it nice and wet for what’s coming. I’ll teach you to eat ass too—lick a man’s hole while stroking his balls. Make him explode down your throat.”

She moaned loudly, tits bouncing as she rode his lap. “Y-yes… teach me everything… I want to be good… for him…”

“For me,” he growled possessively, though she didn’t catch it. He slapped her ass lightly, the sound echoing. “I’ll fuck your throat until you gag, princess. Train you to take it all. Then bend you over and pound that juicy ass while pulling your hair.”

Tae’s pussy clenched, orgasm building fast. “I’m… I’m gonna cum… Uncle Kook, please!”

“Cum for me, baby,” he rasped, grinding furiously, his own release coiling tight. “Soak your panties like the little slut you are. Imagine my cum filling you up—breeding that pink pussy until it drips.”

With a cry, Tae shattered—her body shaking, pussy gushing through the lace, wetting his slacks as waves of pleasure crashed over her. “Ah! Uncle Kook… yes… cumming!”

That pushed him over. Jungkook groaned deep, hips bucking as he came in his pants, hot spurts soaking the fabric, his cock pulsing against her ass. “Fuck, Tae… take it… all mine…”

They panted together, her slumped against his chest, tits heaving. His hands still caressed her ass gently now, possessively.

After a moment, she whispered shyly, “T-thank you… for helping me.”

He smirked, kissing her forehead. “This is just the beginning, princess. We’ve got so much more to learn.”
