Sofia leashes & collars her slave before he services her ass & twat with his tongue. He does his best to worship Sofia's hind end. He really digs deep, rooting around as he tongues her, front & back. Sofia's sub has licking prety time, servicing her ass & twat. Like pig snuffling for truffles, he wallows with his face in her hind end crack, digging deep with his tongue. What will he find there? Does he need to clean her back, or is he merely polishing it? Sofia is certainly enjoying herself ... & we have impression that her submissive is enjoying himself too.
