Gas Mask Slave Fights Against Her Bonds

This is some seriously sick and twisted shit right here! A curvaceous brunette is tied into a latex outfit and then ensconced in a steel chamber, her legs tied together and her arms firmly bound with a steel pole. She has a tight latex mask tied over her face with only a thin tube to breathe through! Her cruel mistress attaches sensors to her so that she can take her revolting pleasure from measuring the panicked girl's vital signs. And panic she does, thrashing vainly against her bonds in a futile attempt at escape. Finally she gives up, sobbing and sagging helplessly against the unwielding metal clamps. How heartbreaking!
