A kinky slave, gagged and tied, is at the mercy of their Mistress. She cruelly finger-fucks the slave's dripping pussy, making them gag on their own drool. The Mistress then inserts a thick dildo into the slave's mouth, gagging them further. She proceeds to flog the slave mercilessly, leaving red welts, as the slave's crotch is viciously fucked, leading to a squirting orgasm that leaves both Mistress and slave drenched in juices.
