The master bedroom was a sanctuary of cold marble and heavy velvet, illuminated only by the dim, golden glow of a bedside lamp. Y/N lay stiffly on the oversized mattress, her heart drumming a frantic rhythm against her ribs. She felt exposed. The silk shorts were so short they barely clung to her hips, and the crop top left her midriff bare, the fabric straining against the fullness of her breasts.

Jungkook lay beside her, propped up on one elbow. He was wearing nothing but black boxers, his muscular chest gleaming in the low light. His dark eyes didn't just look at her; they devoured her, tracing the curve of her waist and the heavy bounce of her chest as she breathed.

"You're shaking, Y/N," Jungkook whispered, his voice a smooth, dangerous honey. "Are you nervous?"

"I... I've never slept in here before," she murmured, her voice barely a whisper. She looked up at him with wide, trusting eyes. "Is this really necessary for my health? The... no underwear part?"

Jungkook let out a soft, patronizing chuckle. "Of course, sweetheart. Your skin is so delicate. If you wear those tight things all night, you'll get rashes. Medical complications. Do you want to be sick?"

"No," she whispered, shrinking back slightly. "I don't want to be sick."

"Good girl." He shifted closer, the mattress dipping under his weight. He reached out, his large hand sliding over her exposed stomach. His palm was hot, sending a jolt through her that she didn't understand. "Now, listen. Since Dad is away, I have to make sure you're developing properly. There are certain... massages... that keep the body healthy. Especially for a girl with a body as beautiful as yours."

Y/N blinked, confused. "Massages?"

"Mhm." His hand migrated upward, his fingers brushing the underside of her breast. Sshhh. "Just relax. If you tense up, it won't work."

He cupped her breast, his thumb grazing the nipple through the thin fabric of the crop top. Y/N let out a small, startled gasp. "Oh!"

"See? You're already reacting," Jungkook murmured, his eyes darkening. He slid his hand beneath the hem of the top, skin meeting skin. He squeezed the heavy mound of her breast, kneading the soft flesh with a possessive grip.

"Jungkook... it feels... strange," she whimpered, her brow furrowing. It wasn't pain, but it was an intensity that frightened her.

"Strange is good," he lied, his voice dropping an octave. "It means the blood is flowing. Now, we have to check the other areas. To make sure everything is... aligned."

His other hand slid down, disappearing beneath the silk of her shorts. When his fingers brushed against her soaking wet heat, Y/N jumped, her legs twitching.

"Ah! What is—?"

"Shhh," he commanded, his fingers diving deeper, finding the sensitive bud of her clitoris. He began to rub it in slow, rhythmic circles. Slap, squelch. The sound of his wet fingers against her skin echoed in the quiet room.

"Does it hurt?" he asked, though he knew the answer.

"No... but... I feel funny. My tummy feels like it's flipping," she breathed, her head tossing back against the pillow.

Jungkook smirked. He could feel her pulsing around his fingers, her innocence a delicious contrast to the raw lust screaming in his veins. She had no idea what he was doing to her, no idea that the 'health' he was providing was nothing more than a prelude to his own hunger.

"You're doing so well, Y/N," he whispered, leaning down so his hot breath tickled her ear. "Just keep trusting me. I'm the only one who can take care of you."
