No Chance Of Breathing Air

Mistress Zora loves her sadomasochistic little games. Today she plays a game with her slave: Who has the longest breath. Peak: its not the slave in front of her! Mistress Zora presses her forearms firmly over his nose and his mouth so its no longer possible for him to breath. Mistress alone control his oxygen. He is absolutely at her mercy and has no chance! Are you her next slave?!?
