Jungkook paced the floor of his bedroom, anticipation thrumming through his veins as he prepared for the final day of his challenge. He had put Isabella through a series of intense and intimate experiences, and today he intended to push her boundaries one last time. The thought of their connection deepening, of solidifying their relationship through pleasure and trust, sent adrenaline coursing through him.

As he dressed, he glanced at the clock—he was running a bit behind. Isabella had been talking to some of the male guards lately, and the thought of her being so close to them ignited a spark of jealousy within him. He couldn’t help but feel possessive; she was his, and he wanted everyone to know it.

Jungkook made his way down the hall, the sound of laughter echoing in the air as he approached the common area. He found Isabella sitting on a couch surrounded by a couple of the guards, their relaxed banter filling the room. He felt a surge of anger at the sight of her so close to them, their laughter ringing in his ears.

“Isabella,” he called, his voice low and commanding.

She turned, her smile faltering slightly as she met his intense gaze. The guards exchanged glances, sensing the tension in the air. Jungkook strode over, unable to contain his frustration. “Can we talk?”

Her eyes widened a fraction, but she nodded, standing up and leaving the guards behind. As they walked into the adjoining room, he closed the door, his jaw clenched tightly.

“What’s wrong?” she asked, her tone curious, yet laced with caution.

“Why were you laughing with them?” he asked, his voice sharper than he intended.

“They were just joking around,” she replied, crossing her arms defensively. “It’s harmless.”

“Harmless? You know how I feel about you being so close to other men,” he growled, his frustration boiling over. “You’re mine, Bella, and I don’t like sharing.”

“Sharing?” she laughed lightly, shaking her head. “You think I want anyone else?”

“I don’t care what you want! You’re not supposed to be with anyone but me,” he shot back, stepping closer. The air crackled with tension, and he could see her surprise morphing into defiance.

“I can talk to whoever I want, Jungkook. You can’t control me,” she retorted, her voice steady.

Jungkook felt a rush of adrenaline and a wave of possessiveness as he realized how much he craved her submission, her obedience. “I’m going to teach you a lesson,” he said, his voice low and dangerous. He grabbed her wrist gently but firmly, leading her into their bedroom.

Once inside, he closed the door behind them, his gaze unwavering as he pulled her to the center of the room. “Bend over my knee.”

Isabella hesitated for a moment, her eyes wide with surprise. “What?”

“Bend over my knee,” he repeated, a mix of desire and authority lacing his voice. “You need to be reminded of who you belong to.”

“Are you serious?” she challenged, though there was a hint of intrigue in her voice.

“Completely,” he replied, his heart racing. There was something thrilling about this moment—about asserting his dominance and showing her just how much he wanted her to understand her place.

She hesitated for another heartbeat before finally complying, her body lowering to his lap. Jungkook felt a rush of power as he positioned her, her bare skin against his jeans, and he could see the way her breath quickened in anticipation.

He lifted his hand and brought it down sharply against her bare ass, the sound echoing in the room. Isabella gasped, her body jolting slightly at the unexpected sting. “One,” she managed to say, her voice a mixture of surprise and exhilaration.

“Good girl,” he praised, bringing his hand down again with a bit more force. “Count every one, or we’ll start from one.”

“Two,” she breathed, the thrill of the moment causing her to squirm slightly on his lap. He could feel her heat radiating through her skin, and the sight of her vulnerable position only heightened his desire.

With each smack, he felt her body responding to the mix of pain and pleasure, and he relished the power he had over her. “Three,” she gasped, her voice rising slightly.

“Thank me,” he demanded, delivering another spank.

“Thank you,” she replied, her voice breathy and slightly breathless.

“Four,” he continued, his hand landing with a satisfying sound.

He picked up the pace, alternating between firm spanks and gentle caresses on her heated skin. He could see her resolve wavering as pleasure intertwined with the sting of his hand. “Five,” she counted, her breath hitching with each blow.

“Six,” she gasped, the sound vibrating with both pain and exhilaration.

“Remember, Isabella, you’re mine,” he growled, relishing the way her body reacted under his hand. “Seven.”

She whimpered slightly, a sound that sent a thrill down his spine. He could tell she was enjoying this, just as much as he was. “Eight,” she breathed, and he could see her fighting to keep her composure, the fire in her eyes telling him how much she craved this.

“Good girl,” he praised again, pushing her limits further. He increased the intensity, and the room filled with the sound of their shared breaths and the rhythm of his hand meeting her skin.

“Ten,” she gasped, her voice laced with excitement and frustration.

“Keep counting,” he urged, his heart racing. “Eleven.”

As he continued, he began to feel a shift in her demeanor. She was beginning to lean into the spanks, her body relaxing against him, and he could sense her surrendering to the moment. It was intoxicating.

“Fifteen,” she moaned, her voice shaking slightly.

“Sixteen,” he continued, feeling exhilarated as her body responded, pushing her further into submission.

“Seventeen,” she cried out, her cheeks flushed, and her breaths quickened.

“Eighteen,” he counted, leaning in closer to whisper in her ear, “Do you feel how much I want you, Bella?”

“Yes,” she gasped, her body arching toward him, craving more.

“Good,” he said, feeling the power coursing through him. He couldn’t believe how much he enjoyed this. “Nineteen.”

By the time he reached eighty, Isabella was panting, her body trembling against him. “Eighty,” she whispered, her voice soft and breathless.

“Thank me,” he commanded, his heart racing with desire.

“Thank you, Jungkook,” she replied, her voice barely a whisper, filled with sincerity and a hint of awe.

“Now, are you going to remember who you belong to?” he asked, his hand still resting lightly on her skin, their connection stronger than ever.

“Yes,” she breathed, her voice filled with conviction. “I’m yours.”

Jungkook’s heart swelled with pride and satisfaction. He had pushed her, challenged her, and in the process, they had both discovered something deeper, something that would bind them together even more. He lifted her from his lap, pulling her into his arms and capturing her lips in a fierce kiss, pouring all his passion and desire into the moment.

As they pulled away, he looked deep into her eyes, knowing that they were embarking on a new chapter together—one filled with trust, love, and unending passion.
