Its a heatwave in NYC and Cybill's slave forgot to set the air conditioner, leaving the Mistress drenched in a thick layer of glistening sweat all over her body.

Cybill's slave must lick her sweat-soaked armpits clean with his tongue, and breath in their odor as punishment before removing her boots and sucking the sweat from between her toes.
