Prove loyalty

"Good," he whispered into her ear, his hot breath sending shivers down her spine. "But words are just that, Zyn. To truly prove it, you're going to have to show me how much you crave servitude to me."

Her eyes widened with a mix of fear and excitement as he tightened his grip, the pressure cutting off her air. Her chest heaved, her pulse racing. He watched her face contort, a mix of panic and arousal that only fueled his desire. "If you want to be mine," he continued, his voice low and menacing, "you're going to have to earn it."

James released her throat, allowing her to gulp in a **** breath. "How?" she rasped, her voice barely above a whisper. "How can I prove my loyalty?"

He stepped back, admiring the way she knelt before him, her eyes pleading. "Just as Mom did," he said with a cruel smile, "and as Remy did to me. You need to show me how much you want to be mine, by serving me with your mouth."

Zyn's heart raced, the mind control making it impossible for her to resist. She reached for his pants, her trembling hands eager to obey. She unzipped him and pulled them down, his cock springing free, hard and demanding. But instead of wrapping her lips around it, as she desperately wanted to do, she found herself face to face with his asshole.

James slapped her across the cheek, the sound echoing in the quiet room. "What did I say?" he barked, his eyes dark with anger. "You're not worthy of my cock yet."

The slap stung, but it also sent a jolt of excitement through Zyn. She felt a strange mix of fear and desire, the whispers in her head growing more insistent. "Y-yes," she stuttered, her voice shaking. "I-I'll do it."

He grabbed her by the hair, yanking her closer. "Spread my cheeks," he ordered, his voice harsh. "And get to work."

Zyn's eyes widened with horror, but she didn't fight. Instead, she reached up with trembling hands and pulled his cheeks apart, revealing his puckered hole. The smell was overwhelming, but she knew she had ****. She leaned in, her tongue tentatively touching the tight ring of his ass.

James groaned, the sensation surprisingly enjoyable. "That's it," he murmured, his voice a mix of pleasure and control. "Show me how much you want to be my slut."

Her tongue grew bolder, licking and probing, the taste of his ass mixing with the sweetness of her submission. The mind control had taken over completely, her thoughts consumed by the need to please him.

He pushed her face closer, the pressure of his ass on her nose making her gag. "You're going to love this," he said, his voice a dark promise. "You're going to crave it."

The whispers grew louder, drowning out any remaining doubt. Zyn nodded, her mouth and nose buried in his ass, her tongue moving with an eagerness that surprised even her. The mind control had done its job, turning her into a willing participant in his depraved fantasy.

As she licked and kissed, James's cock grew harder, his hand pumping it in time with her movements. "Good," he said, his voice a harsh whisper. "So good."

The room grew hazy, the only focus the feel of her brother's asshole on her tongue. The mind control had turned her into a creature of pure desire, her will bending to his every whim.
