Mistress Erinia, Domme Hades, and Mistress Samantha are going to use the slave for their perversions. They'll gag him so his mouth is open, allowing them to use him as an ashtray and spit into his submissive mouth. They'll humiliate him in various shameful ways while the slave drools from the gag, all while the Goddesses enjoy the rooftop views in their sexy lingerie sets under their coats.
