Submissive female training - femdom spanking

Jana is on the bed, her arms extended in front of her, tied to the wrought iron headboard. She waits on her knees for her mistress. She knows that she's been bad and that she'll have to pay dearly for her sins. Then, suddenly, she feels the slap of a hand against her ass.
"Have you been bad?" Mistress asks.
"Yes!" Jana cries.
Jana's ass is spanked again, harder this time.
"I'm sorry," she says, and then adds quickly, "Mistress." Again and again Mistress spanks her, making her ass cheeks pink and her pussy wet.
Then it stops.
Jana takes a deep breath, recovering from the spanking she has received.
She shifts her weight from knee to knee and is reprimanded with a sharp, "Don't Move!"
