During one of Kisara's performances, Seto Kaiba found himself unusually captivated. Her voice, her presence, everything about her aroused a desire he could no longer ignore. Determined to act on his feelings while maintaining his characteristic stoicism, he decided to propose a business deal.

After the performance, he arranged for Kisara to come to his office. She arrived, her curiosity piqued by the sudden invitation.

"Mr Kaiba," Kisara greeted, her eyes gleaming with interest. "To what do I owe this unexpected meeting?"

Kaiba, seated behind his large mahogany desk, gestured for her to sit. "I have a proposal for you, Kisara."

She raised an eyebrow, intrigued. "A proposal? I'm listening."

"I've been considering a... partnership of sorts. A mutually beneficial arrangement."

Kisara's lips curled into a playful smile. "Go on."

Without breaking his business-like tone, Kaiba continued. "I've been thinking about your suggestions to try out more of the earthly pleasures. Thus, I'm proposing to you a relationship without any emotional entanglements. Just physical intercourse. No strings attached."

Kisara leaned back in her chair, her amusement evident. "So, you're offering me a contract for a purely physical relationship?"

Kaiba nodded. "Precisely. I believe it would be advantageous for both of us."

Kisara's eyes sparkled with mischief as she leaned forward, meeting his gaze directly. "And what are the terms of this... arrangement?"

Kaiba slid a contract across the desk, his eyes never leaving hers. "The terms are outlined here. It ensures complete discretion and outlines the expectations and boundaries."

Kisara picked up the contract, skimming through it while occasionally glancing up at Kaiba. "You really do think of everything, don't you?"

"I prefer to be thorough," Kaiba replied, his voice steady.

"And why would I accept this, Mr Kaiba?"

Kaiba leaned forward, his lips showing just a ghost of a smile: "As I already said, Ms Kisara, I prefer to be thorough in everything I do."

Kisara felt her breath quicken at the sound of these words. She realized that, even though the contract seemed degrading, she wanted exactly this kind of relationship. The pressures of the public and the media didn't allow her to be entangled in any more profound relationship with anyone, at least not in the way she wanted - without sharing it with the rest of the world. What's more, the attraction to the young CEO was undeniable, and she thought that, after all, it could be lots of fun.

She set the contract down, her smile widening. "Alright, Mr Kaiba. I accept your terms."

Kaiba handed her a pen, his expression unwavering. Kisara took the pen, her eyes locked onto him as she signed the contract. The moment she put down the pen, a charged silence filled the room.

Without breaking eye contact, Kaiba stood and walked around the desk. Kisara rose to meet him, the tension between them palpable. As soon as he was within reach, he closed the distance, and their lips met in a fierce, passionate kiss.

Their hands roamed, exploring each other with a hunger that had been building for weeks. Kaiba's typically composed demeanor gave way to raw desire as he pulled her closer, deepening the kiss.

Kisara responded with equal fervor, her fingers tangling in his hair as they lost themselves in the intensity of the moment. All the unspoken attraction, the playful flirting, and the restrained emotions finally found release. As their kiss grew more heated, the lines between business and pleasure blurred, and they surrendered to the passion that had been simmering beneath the surface.
