Boot Cleaning Games

Mistresses Simone and Brianna are relaxing when Mistress Julie brings in a chastised stable bitch for their amusement. After having him grovel before them and lick their boots clean, the Mistresses decide to make the bitch earn his worship, keeping their boots just out of the reach of his tongue. Brianna reminds him that she holds his chastity key and if he ever hopes to be let out, he better impress the Mistresses with his efforts. Will the slave prove his enthusiasm for his Mistresses' boots, or is extended chastity in his future?
