Sometimes Sophie likes having her ass licked while she watches tv. Other times, she just wants the slave to deeply inhale her ass fumes. So she calls over the slave who already has his mouth totally taped shut, and has him bury his nose in her ass and inhale deep. "Sniff!" she commands as the slave is to breath from his nose, with his only air now coming direct from her anus. "Keep sniffing my ass" Sophie commands again as the slave struggles to breath. The fumes must be horrible, but Sophies ass air is all the slave gets to inhale, straight from her anus right into his nose.
