Returning to find their slave in the cage, Master Xena wants some work and entertainment from him.
While she likes him in the cage, he is unlocked to give easier access to clean the dirty boots with his tongue.
The dirt and grime is visible as he works on the shoes, licking and slurping to get the mud and muck off.
Deciding she wants a seat, Xena has him as a stool to step upon before he works on the soles now she is sat.
This round of servitude ends when he is used as a foot rest to the boots.
