N148 Bertie Smother Spitting Hand Over Mouth Smother

Bertie made her slave lie down under her, because Mistress wants to have fun and check how much time slave will be able to stay without air! Mistress closes her nose, her mouth, while the slave suffocates, mumbles, and begs. Bertie amuses that the slave is under her, resists, although nothing can be done with it, because otherwise her punishment will be even worse. Slave feels sweet saliva of her Mistress, who just has fun and plays games.
