Tae stood in front of the full-length mirror in their luxurious 3BHK apartment, admiring her own reflection like the vain little slut she was. At 30, she was pure sin wrapped in soft white skin. Her long black hair cascaded down her back in loose waves. Her lips were naturally plump and pink, always glossy as if she’d just sucked a cock. Her tits were massive — heavy, round DDs that strained against any top she wore, nipples usually hard and poking through fabric. Her waist dipped in sharply before flaring out into wide hips and a fat, juicy ass that jiggled with every step. Between her thick thighs sat her favorite treasure: a puffy, pink fat pussy with plump outer lips that swelled when she was horny — which was almost always.

Today she was dressed like the whore she loved being. A tiny white crop top that barely covered the underside of her big tits, the thin material so tight her dark nipples were clearly visible. Below that, a microscopic black pleated skirt that rode up her ass cheeks every time she moved, flashing the fact that she wasn’t wearing panties. Her smooth white thighs were bare, and on her feet were strappy silver heels that made her ass pop even more. No bra, no panties — just the way she liked it.

She turned sideways, cupping her heavy breasts and squeezing them together. “Mmm… look at these fat tits,” she murmured to herself, voice breathy. “No wonder every man wants to bury his face in them.”

The apartment was beautiful — high ceilings, big windows overlooking the city, expensive furniture Namjoon’s big professor salary paid for. Tae loved the comfort. That was exactly why she had married him ten years ago. Namjoon was 40 now, tall, broad-shouldered, and ridiculously handsome with sharp jawline and deep dimples. But at 30, when she was 20, she hadn’t married him for love or great sex. She married him because he was stable, brilliant, and earned very well as a Biology professor at one of the country’s top universities. Life with him meant no money worries, a fancy apartment, and the freedom to be the secret slut she was.

Their sex life? Pathetic.

Namjoon was obsessed with his career. His biggest dream was to become the youngest Head of Department in the Biology faculty. He spent every evening buried in research papers, preparing lectures, or mentoring his star students. Sex with him was once every two or three weeks, and even then it was quick, mechanical, and boring. He’d climb on top, thrust a few times with his eyes half-closed like he was thinking about cell division, cum inside her, then roll off and go back to his laptop.

Tae was dripping wet almost 24/7 and she refused to live like a nun.

That’s why she had become such a filthy cheater.

While Namjoon was at the university, Tae was busy getting her pink fat pussy pounded by whoever was convenient. The young delivery guy who brought groceries got his cock sucked in the kitchen last week. The married neighbor from floor 12 fucked her against the balcony railing while his wife was cooking dinner. Two of her friends’ husbands had taken turns spit-roasting her in a hotel room during a “girls’ night.” And sometimes, when she was really desperate, she’d visit Namjoon’s father at his house and let the old man rail her senseless on his couch, his wrinkled hands squeezing her big tits while he groaned, “You’re such a naughty daughter-in-law…”

Namjoon? Completely oblivious. He thought his beautiful wife was just “bored at home” and “liked dressing sexy for him.”

Right now, Tae was home alone again. Namjoon had left early for university. She was already horny. She walked to the bedroom, pulled out her favorite thick dildo from the nightstand, and lay back on their king-sized bed.

“Fuck… Joon never fucks me like I need,” she whined to herself, spreading her thick thighs wide. Her pink fat pussy was already glistening, puffy lips swollen and slick. She rubbed the fat head of the dildo against her clit and moaned loudly.

“Mmmhh… yes… bigger than Joon’s dick… ahh!”

She pushed it inside her tight, wet hole, the squelching sound filling the room as she started fucking herself hard.

“Fuck me… harder… I need real cock!” she gasped, hips bucking. Her big tits bounced wildly under the tiny crop top as she imagined a thick cock stretching her instead of the toy. “I’m such a slut… Joon’s wife but I crave other men’s cum…”

She came hard, thighs shaking, pussy gushing around the dildo, but it still wasn’t enough. She needed the real thing soon.

Meanwhile, at the university, Professor Kim Namjoon was in his element.

He stood tall and muscular in front of the lecture hall, his deep voice commanding attention as he explained complex biological processes. At 40 he still looked incredibly handsome — sharp features, broad chest filling out his crisp shirt, sleeves rolled up to show veined forearms. The female students whispered about how hot he was, but Namjoon barely noticed. His mind was only on one thing: becoming the youngest Head of Department.

And for that, he needed his star student to perform exceptionally.

Jeon Jungkook.

23 years old, tall — easily 6’1 — with a lean, muscular body he kept toned from early morning gym sessions despite being a total nerd. Handsome face with big doe eyes, sharp jaw, and a shy but charming smile. Messy black hair that fell over his forehead. Jungkook was the brightest biology major in the entire university — quiet, focused, always sitting in the front row taking detailed notes. He wore simple clothes — fitted black t-shirts that showed off his toned arms and chest, and jeans that hugged his long legs and surprisingly thick ass from all the squats he did.

Namjoon considered Jungkook his protégé. The boy had the potential to break every academic record in the department.

“Jungkook,” Namjoon said after the lecture, calling him to his desk with a proud smile. “Your last paper was outstanding. If you keep this up, you’re going to score the highest marks in the university’s history. That will look incredible on my record when I apply for HOD.”

Jungkook rubbed the back of his neck shyly, his deep voice soft. “Thank you, Professor Kim. I’m really trying my best. Your guidance means a lot.”

Namjoon clapped a big hand on the younger man’s shoulder. “Keep it up, son. I’m counting on you.”

Jungkook nodded, packing his books. He had no idea that the professor’s beautiful wife was at home right now, legs spread, fucking herself silly while moaning about needing “real cock” because her husband was too busy chasing promotions.

Back in the apartment, Tae had just finished her second orgasm with the dildo. She pulled it out slowly, watching her creamy juices coat the thick toy. She brought it to her pink lips and licked it clean with a filthy moan.

“Tastes so good… but I need fresh cum,” she whispered, eyes dark with lust. “Maybe that delivery boy will come again today… or maybe I should text Joon’s dad…”

She stood up, not bothering to clean her dripping pussy. The juices were already sliding down her inner thighs. She adjusted her tiny skirt, making sure it barely covered her ass, and checked her phone.

No messages from Namjoon. He’d probably be late again tonight.

Tae smirked, her pink lips curling wickedly.

“Good. More time for me to be a proper slut.”

She walked to the kitchen, hips swaying, big ass jiggling under the short skirt, already thinking about whose cock she would take next.

Little did she know that soon, her husband’s favorite nerdy student — the tall, handsome, muscular Jungkook — would walk into her life and give her exactly the kind of filthy fucking she’d been craving.
