A symphony of groans and wet slurps fills the room as the slave, eyes watering, tongues his mistress' asshole with fervor. Her asshole puckers and relaxes under his expert ministrations, the slave's tongue darting in and out, mimicking the fucking he craves. The dominatrix, lost in pleasure, grinds against his face, her asshole dripping with his saliva and her own lubrication. The slave, hard and aching, wishes for release, but his mistress' pleasure is his only concern, his only reward.
