"My father is a parasite," JK spat, slamming a leather folder onto the mahogany desk. He glared at Y/N, his eyes dark with irritation. "Come here. Now."

He hauled her onto his lap, his fingers digging into her waist. With a sharp tug, he ripped her blouse open, buttons scattering across the hardwood floor. Y/N shivered, her face flushing a deep crimson, but she leaned into him.

"You're so tense," she whispered.

"Shut up and let me breathe," he muttered. He leaned down, biting the tender swell of her breast. He gripped her breasts firmly, squeezing them like stress balls to vent his frustration. Y/N let out a long, trembling moan, her head falling back as he spent the hour kneading her flesh.

Weeks later, the hunger shifted. He stripped her completely, pushing her onto the cold surface of his office table. As he slid two fingers into her damp heat, she gasped, clutching the edge of the desk.

"Wait... JK, I'm a virgin," she breathed, her chest heaving.

"I can tell. You're tight," he murmured. He didn't stop. He spent an hour between her thighs, his tongue swirling against her clit, the wet, squelching sounds of his mouth filling the quiet office until she collapsed in a heap of spent nerves.

He began bringing her to his mansion, treating her as his private sanctuary. One afternoon, he pinned her to the silk sheets, her breasts spilling from a lace bra. He sucked her nipple greedily, swirling his tongue around the peak.

A soft knock echoed through the room.

"JK? It's Sera. I'm downstairs," a voice called.

JK didn't pull away immediately. He looked toward the slightly ajar door, knowing Sera was watching. He wore a knowing smirk.

"Go back down, Sera. I'll be there in a minute," he called out. He looked at Y/N, his voice suddenly honeyed. "She's just my father's friend's daughter. She's like a sister to me."

Y/N beamed, pressing her lips to his. "I didn't know you had a sister-figure like that."

Downstairs, Sera stood in silence, her heart aching. When JK finally emerged, dressed and composed, she didn't mention the scene in the bedroom.

"Let's finalize the date," Sera whispered.

"I'm busy for the next six months," JK replied coldly. "Ask me then."

The facade continued until the lust became an itch he couldn't scratch. He drove her into the mattress of his bed, his hard cock breaching her virginity in one harsh thrust.

"Stop! It hurts!" she screamed, blood staining the white sheets.

JK paused for two minutes, his breath hot against her neck. Then, he began pounding into her, the rhythmic slap-slap-slap of his balls against her skin echoing. He railed her all night, later repeating the act in the leather backseat of his car.

One morning, Jimin leaned against the office door, a predatory grin on his face.

"I heard you've been railing her non-stop, JK," Jimin chuckled. "I'm stressed too. Let me have a turn at that hole."

JK shrugged, devoid of affection. "She's a toy. But she's too innocent to agree to a share."

"I have a plan," Jimin whispered.

JK stirred a white powder into Y/N's coffee. He handed it to her with a fake, tender smile.

"Drink this, sweetheart," JK whispered. "I have a new kink. I want to see you unconscious on the sofa while I... explore you."

Y/N smiled, sipping the bitter brew. "Anything for you, JK."
