Julian leaned over her, his hand tangling in her hair.
"You can do it," he murmured against her lips. "You're my good little whore."
The headmistress felt Julian's cock begin to harden once more, his body already preparing for the next round. She took a deep breath, bracing herself for the onslaught that was to come.
He slammed into her again, the sound of their flesh slapping together echoing through the room. Julian's hand found her clit, his thumb rubbing it in circles as he fucked her mercilessly.
He watched her face contort with every stroke, her eyes rolling back in her head as she approached another climax.
The headmistress could feel herself losing control, her thoughts a jumbled mess of pleasure and pain. Julian's fingers danced over her clit, bringing her to the brink again and again, only to pull back at the last moment.
Julian's cock slammed into her, each thrust a declaration of his dominance. The headmistress felt her body begin to shake, the beginnings of a sixth orgasm building within her.
Julian's eyes never left hers, his expression a mix of triumph and lust. "Cum for me," he ordered, his voice a low growl. And she did, her body obeying his command without hesitation.
The headmistress's muscles tightened around his cock, her body trembling as the orgasm washed over her. Julian's strokes grew more erratic, his own release close at hand. And then, with a final, brutal thrust, he came again, filling her pussy with his hot cum.
Julian's hand reached up to cup her face, his thumb tracing her bottom lip as he whispered, "You're mine." She nodded, her eyes glazed with lust. Julian pulled out of her, his cock still hard.
Julian's cock was still demanding, still ready for more. She knew she would take him again, would endure whatever he had in store. After all, she had agreed to fifteen rounds.
Julian smirked, his eyes never leaving hers. He knew she was close to breaking, that she was on the edge of exhaustion. But he also knew she wouldn't give up, not until she had proven herself to him.
He positioned his cock at her entrance once more, ready to plunge into her depths again.
"Are you ready?" he asked with a grin on his face.
Julian then went ahead and fucked her till her fourteenth orgasm. She was his slave now, her only purpose to serve his desires.
He then positioned the headmistress on the floor, her legs spread wide as he knelt before her. The headmistress watched as he took his cock in hand, his eyes never leaving hers.
Julian stroked his cock as his cum splattered on the floor.
"Lick it clean," he ordered, his voice a demand.
And she did, her tongue darted out to taste Julian's cum off the floor. Julian's cock was still hard, and she knew what was to come. She had to be ready for the final round, had to give him everything he demanded.
The headmistress then felt Julian's cock push into her again, his strokes slow and deliberate. His hand wrapped around her neck, his grip tightening as he sucked her breast.
Julian's cock swelled inside her. The headmistress's mind was a blur of pleasure and pain, her thoughts consumed by his relentless fucking.
"Ah, yes," she screamed, her voice a ragged cry. "Fuck me, Destroy my pussy."
She came for the fifteenth time, her body shaking uncontrollably. Julian's cock swelled even more, his own orgasm close.
Her words seemed to push him over the edge, his hips bucking as he filled her with his cum for the fifteenth time. The headmistress felt herself go limp, her body no longer her own.
Her body was his, her mind his to command. She had been completely broken.
Julian stepped back, his cock finally softening. The headmistress lay there, her legs wide open, her pussy dripping with mixture of Julian and her own juices.
She knew that she would serve him again, that she would beg for his touch. Julian leaned down, his lips brushing against her ear.
"We will fuck again but next time you will take me 30 times," he murmured, his voice a dark promise
The headmistress closed her eyes, her body trembling with the aftershocks of her climax. Julian had taken everything from her, had reduced her to a mere slut for his pleasure.
And yet, she felt a strange sense of contentment, a satisfaction that came from knowing she had served him well. She was his slave, and she would always crave the pain and pleasure that came with his.
