Dhyannas brave facade crumbled as soon as the door slammed shut behind the Headmaster. Her fear and lust were clearly visible in her brown eyes and heaving chest. She moaned a little as the machine brought her closer and closer to an orgasm. Then it stopped...a small whimper escaped her lips then the machine started again.

Closer and closer then off....the cycle repeated and repeated and repeated until she was ready to sell her soul for an orgasm. Her whimpers turning to groans of dismay then to moans of pain/pleasure and finally to screams of frustration.

"PLEASEEEEEEE LET ME CUM" she finally screeched like an animal caught in a trap. Panting, covered in sweat begging incoherently she had no idea of the passage of time. All she knew was that if she did not cum soon she would lose her tenuous grasp on reality.
