Collared and restrained, the slave's ass is red from the impact of her Mistress's paddle. Breathless and aroused, she begs, "Please, fuck my ass. I've been a good slave." Her Mistress, satisfied with her training, lubes up her massive cock and plunges it into the slave's tight asshole, face-fucking her brutally while she deepthroats his cock, gagging on his length.
