Merciless Air Control

Mistress Roxana is very curious as to how long her slave can hold her breath. She presses both hands over her face and takes the air away from her. How long will the bitch last?! No amount of moaning and whining helps. Mistress Roxana is merciless with her and presses her into her face again and again. The tied slave cannot defend herself and must helplessly endure her Mistress brutal air control.
