As this scene opens sexy Mistress Mercy is dragging her slave up the stairs to the bedroom, on all fours, where she plans to test his ability to hold his breath under her ass. She seductively walks up the stairs showing off her amazing butt all the way, stopping occasionally to let the slave sniff her hole or kiss a butt cheek. Once upstairs she has the slave lay on the bed and mounts his face in a reverse position. She settles in on his face bu wiggling and gyrating her ass until it feels just right. Beautiful views of an ass any man would want to be under, submissive or not. She leans back and puts her arms on the bed and swinging side to side slamming his face repeatedly.

Now she sits firmly on his face and comments that yesterday he lasted two minutes and now she wants to see if he can manage three. She continues to wiggle her ass but makes sure there is a tight seal. Mercy is shocked when at 30 seconds the slave is already kicking for air. He lasts only 50 seconds in total. "A cold dark cage for you tonight" she tells him. Sometimes a slave can be so overwhelmed by the soft beautiful flesh of the Mistress's ass that they forget to breath properly, as is the case here. No excuses! Mercy turns around sitting on his stomach and resting against his bent legs, using him as a chaise she places her feet on his face. The slave licks and kisses them, they're dirty from her earlier walking in the garden, but after his face sitting fail he's lucky to be getting anything at all.
