Bound and gagged, the sissy kneels before their mistress, ready to learn the ultimate act of submission. The mistress, clad in black panties and heels, runs her hands through the sissy's hair, pushing them down onto her crotch. The sissy inhales the scent of their mistress's panties, feeling the heat of her pussy through the thin fabric. The lesson begins, the mistress's voice stern yet seductive, guiding the sissy's tongue and lips along her cock, teaching them the rhythm and pressure to bring their mistress to ecstasy.
