Bella is a mistress and Tomiko is her slave. Before the session starts, Tomiko explains to her mistress she likes smelling stinky feet, foot gagging and hand over mouth.
Bella ties up Tomiko on the couch. She puts a stinky nylon foot over her mouth and nose. Tomiko has to smell the foot. Bella puts her both nylon feet over her mouth and nose. She holds her breath with them.
The mistress takes off the stockings and continues her foot gagging action. Tomiko can't breathe under stinky feet of her mistress, who has no mercy and gags her several times.
Bella changes the method. She holds Tomiko's breath with a tight handgag action. She does it with different poses, like a single hand over her mouth and nose, covering her mouth with a hand and pinching her nose with other one, gagging her from behind with both hands over her mouth and nose. The mistress keeps the hands for long time.
