Chapter 1: "The Awakening"

It was a slightly rainy summer day; the rain was pattering monotonously against the expansive, floor-to-ceiling windows of the JYP building. The city of Seoul outside was painted in a moody, silver-gray wash of precipitation, the distant, muffled sounds of traffic acting as a low hum against the glass. Nineteen-year-old Sullyoon, the shy visual of NMIXX, stepped softly into the main dance rehearsal room. Her heart was beating a frantic rhythm against her ribs, fluttering nervously beneath her small, A-cup chest.

She was dressed for comfort in a light, grayish-blue, loose-fitting sweatshirt-style pullover hoodie that draped over her petite frame, paired with dark gray, charcoal workout leggings that clung tightly to her slender legs. Twice had been dancing in this exact room just an hour earlier. The air was still thick and warm, deeply intoxicating, filled with a heady mixture of sweet, expensive floral perfumes, the lingering, musky scent of fresh exertion, and the faint, teasing aroma of melted vanilla candle wax coming from a decorative jar left near the sound system.

Sullyoon’s wide, brown deer eyes darted around the empty studio. Her mind was racing, plagued by the scandalous whispers she had heard from ITZY’s Lia. The rumor was absolutely insane, practically unbelievable: that every single member of the pristine, legendary group Twice was regularly fucking their European bodyguard and dance trainer, Y/N.

Y/N was infamous in the company. A thirty-year-old European giant standing at 188 centimeters and weighing 90 kilograms of pure, densely packed muscle. He had sharp brown eyes, perfectly styled short black hair, and was always clad in a fitted Adidas training suit that did nothing to hide his intimidating, alpha-male physique. In the dance room, he was a ruthless, strict tyrant who adhered rigidly to the rules, demanding absolute perfection. The idea that this uncompromising disciplinarian was secretly ravishing the nation’s top idols was a thought that made Sullyoon’s thighs involuntarily press together, a strange heat blooming in her core.

Lia had sworn there was a secret room. A hidden sanctuary right here in the studio.

Sullyoon approached the massive mirror wall, the one normally used by the idols to critique their every movement during grueling rehearsals. She trailed her delicate fingertips along the cool, pristine glass. Where could it be? she thought, sliding her hands lower, feeling the smooth texture against her skin. Suddenly, her palm pressed against a specific, barely noticeable indentation near the corner framing.

A soft, pneumatic hiss echoed in the quiet room. Sullyoon gasped, taking a step back.

A large section of the mirror wall smoothly popped outward, swinging open like a heavy door completely devoid of a handle. The warm, inviting air that rushed out of the hidden space hit her face like a physical caress. It smelled intensely of raw, unbridled sex—a potent cocktail of feminine wetness, rich masculine musk, sweat, and sweet massage oils.

Trembling, Sullyoon slipped inside the secret room, her breath catching in her throat as the mirror-door clicked softly shut behind her, leaving a tiny, imperceptible crack for her to peek through if needed.

The atmosphere in the secret room was entirely different from the sterile dance studio. It was an opulent, luxurious sanctuary. Golden candlelight flickered from sconces on the wall, weaving an intoxicating dance of light and shadow with the silver moonlight filtering through a small, frosted ventilation window. The room was meticulously climate-controlled, the temperature a perfectly balmy warmth that made skin crave touch.

In the center of the room sat a plush, deep velvet sofa positioned in front of a massive 52-inch TV, which was currently displaying a crackling, digital fireplace, adding to the flickering, fiery ambiance. Beyond the sofa was a massive, king-sized bed draped in expensive, dark crimson silk sheets. On the far wall, an entire shelf was dedicated to an array of high-end, silicone "toys," glowing softly in the dim light.

But what caught Sullyoon’s wide eyes the most was a huge, meticulously organized weekly schedule pinned to a corkboard, elaborately decorated with drawn hearts and dozens of explicit Polaroid pictures. She crept closer, reading the bold lettering.

MONDAY - Momo

TUESDAY - Sana

WEDNESDAY - Mina

THURSDAY - Nayeon

FRIDAY - Tzuyu

SATURDAY - Chaeyoung (morning), Jihyo (evening)

SUNDAY - Dahyun (morning), Jeongyeon (evening)

Beneath the names were Polaroids of each Twice member in various states of utter, blissful degradation. Sullyoon’s jaw dropped. There were pictures of the girls totally naked, wearing sexy, strappy underwear, their faces flushed, their mouths completely filled with thick, white cum, their perfect tits painted with Y/N’s seed, and their cunts glistening and stretched. It was a gallery of absolute, shameless devotion.

Before Sullyoon could process the sheer magnitude of her discovery, a sudden, breathy moan shattered the quiet.

"Oh... God... Y/N... fuck..."

Sullyoon froze, immediately ducking behind the heavy velvet sofa, peering through the small gap between the armrest and the wall.

At the far end of the room, pressed mercilessly against another mirrored wall, was Jihyo. The proud, authoritative, 27-year-old leader of Twice.

Jihyo’s usual immaculate styling was completely ruined. Her hair, usually styled half-up with loose strands framing her face and a high ponytail, was now a gorgeous, sweaty mess sticking to her flushed cheeks. Her attire was utterly destroyed. The oversized red hoodie-like jacket with the dark design was unzipped and forcefully shoved down her shoulders, pinning her arms. Her matching red sweatpants, bearing the word "TUSSY" in black lettering on the waistband, were pooled disgracefully around her ankles alongside her sneakers.

The cropped black sleeveless top she wore had been violently tugged to the side. One of her heavy, gorgeous D-cup breasts was completely hanging out, the large, dark nipple pebble-hard and glistening with saliva. The small red cross pendant she wore on a light-colored necklace swung wildly against her bare collarbone with every brutal impact.

Behind her stood Y/N, fully dominating the proud leader. His Adidas training jacket was discarded, revealing a tight black t-shirt that stretched over his bulging, muscular chest and thick arms. His track pants were pulled down just enough to free his massive, rigid, 18-centimeter cock, which was currently buried to the hilt inside Jihyo’s soaking wet pussy.

Sullyoon watched, mesmerized and horrified, as Y/N pulled his hips back, exposing the thick, glistening shaft before driving it forward with a loud, wet SLAP. The sound of flesh slapping against flesh echoed through the luxurious room, accompanied by Jihyo’s high-pitched, desperate squeals.

As Y/N’s thick cock pushed forward, it spread Jihyo's swollen, flushed labia apart like Moses parted the sea. She was so incredibly wet that the slick sounds of their friction sounded exactly like the crashing of an ocean wave, her copious juices dripping down the inside of her thighs and leaving wet, glossy streaks on the mirrored glass she was pinned against.

"Fuck, Y/N... yes! Don't stop... oh my god, I just can't get enough!" Jihyo moaned out loud, her breath fogging up the mirror in front of her face. "I can't get enough, even though you destroy me every single Saturday since Twice had our debut... Ah! Right there! Just like back then... in that dusty hospital old bed during the 'Like Ooh-Ahh' filming!"

Y/N let out a deep, rumbling chuckle that vibrated through the room. His large, calloused hand reached up, his thick fingers wrapping securely around Jihyo’s throat. He didn't squeeze hard enough to hurt her, just enough to restrict her airway slightly—choking her neck a little, exactly the way he knew she absolutely loved. Jihyo let out a breathy, stuttering gasp, her dark brown eyes rolling back in pure, unadulterated pleasure.

"Is that right, little leader?" Y/N teased, his voice dripping with dark, witty amusement and dominant authority. "Are you proud to be the leader of a nymph band? A group of perfectly trained, award-winning fucktoys for your strict bodyguard?"

Jihyo’s face was mashed against the cold glass, her heavy, exposed breast flattening beautifully against the mirror with every thrust. She whined eagerly, her hips snapping back to take more of his impressive length. "Yes! Mmh... yes, Sir! We are! We are all just your personal, desperate fuckholes! Oh God, stretch me!"

Sullyoon clamped a hand over her own mouth to stifle a shocked gasp. The proud, proper leader of Twice was begging like a rabid animal in heat.

Y/N’s eyes darkened with raw lust. He grabbed both of Jihyo’s hands, pulling them firmly behind her back with one massive hand, completely incapacitating her. With his other hand on her hip, he began to thrust his 18-centimeter cock deeper and faster into her slick, thoroughly wrecked pussy.

SLAP! SLAP! SLAP!

The rhythm was relentless, a hard, deep, rhythmic fucking that left absolutely no room for mercy. With every brutal thrust, fresh waves of sweet, viscous juices ran out of Jihyo’s overstimulated cunt, splashing onto Y/N’s thighs. Her body was completely limp, surrendered to the pleasure. She was left literally hanging in his grip—she could only stand on her trembling legs because her flushed face and heavy tits were pressed so hard against the unyielding mirror by the sheer, brute force of Y/N’s thrusts from behind.

"Take it, Jihyo. Take every inch of your trainer," Y/N commanded breathlessly, his hips snapping like a whip.

"I'm taking it! Ah! I'm yours... purely yours!" she screamed, her body convulsing as the intense, all-consuming lovemaking pushed her to the edge of the precipice.

The tension in the room was thick enough to cut with a knife. The scent of their arousal was pungent and overwhelming. Sullyoon could actually smell the metallic tang of sweat mixing with the musky, heavy scent of female arousal and male testosterone. Jihyo was trembling violently, her muscles spasming in exquisite agony as the first powerful wave of ecstasy crashed over her. She let out a long, shuddering, throat-tearing climax, her inner walls clamping down mercilessly around Y/N’s thick shaft, milking him with every involuntary contraction.

Y/N groaned, a deep, guttural sound of immense satisfaction. He let her ride out her massive orgasm, continuing to pound into her violently twitching, flooding core for a few more excruciatingly pleasurable seconds.

Jihyo loved the taste and feel of Y/N more than breathing. When she was more than finished, completely spent and dripping a puddle onto the floor, Y/N’s glossy, saliva-and-juice-coated cock slipped out of her dripping pussy with a loud, wet pop.

Instantly, the dynamic shifted. Jihyo didn't hesitate. Even though her legs were like jelly and she was panting heavily, her chest heaving, she slowly turned around. She sank completely onto her bare knees on the soft, luxurious carpet, surrounded by her discarded red "TUSSY" sweatpants. She looked up at him pleadingly, her dark brown eyes wide, glassy, and full of immense, hungry anticipation.

Sullyoon watched, her own heart hammering against her ribs, as Jihyo reached out with delicate, trembling hands. She guided Y/N’s thick, throbbing, 18-centimeter shaft toward her face.

This was the part of her Saturday evening she lived for.

Jihyo opened her mouth, her plush, pink lips parting to reveal her warm, wet tongue. She leaned forward and took the very tip of his cock into her mouth, letting out a soft, muffled hum of utter delight. The intense, passionate blowjob scene that unfolded before Sullyoon’s hidden eyes was exquisitely detailed and agonizingly slow. Jihyo worshipped him. She began with sensual lip-to-body worship, pressing soft, agonizingly tender kisses along the thick, bulging veins of his shaft, breathing her hot breath against his feverish skin.

She licked a long, wet stripe from the base all the way up to the slit, swirling her tongue expertly over the sensitive head, tasting her own musky juices mixed with his salty pre-cum. Y/N hissed, his hands coming down to tangle in her messy, half-up hair, guiding her rhythm.

"Good girl. Suck it. Show me why you're the leader," he whispered, a smirk playing on his lips despite the heavy, intoxicating tension gripping his body.

Jihyo obliged with fervent zeal. She rhythmically took Y/N’s thick cock deep into her mouth, her lips wrapping tightly around the girth, creating a perfect, wet vacuum. Her head bobbed back and forth, her cheeks hollowing out as she sucked with unbelievable power and devotion. Her tongue curled and swirled around the shaft inside her warm, slick mouth, providing deep, relentless oral stimulation.

While her mouth worked miracles, her hands were not idle. With one hand, she lovingly and gently massaged his heavy, swollen balls, kneading the sensitive skin with expert precision. With her other hand, she stroked the thick base of his 18-centimeter shaft, matching the exact rhythm of her bobbing head, making sure not a single millimeter of his flesh went unloved.
