Erika Lust's "Faithful Dog" is a symphony of senses, with the crisp snap of latex, the wet smack of kisses, and the deep, guttural growls of a man reduced to his basest desires. The dominatrix, her eyes gleaming with sadistic pleasure, guides the puppy's eager tongue to her pussy, making him lap and lick until she cums, her juices dripping down his chin. She then takes his straining cock into her mouth, sucking him off until he explodes, his hot cum spilling out and coating her latex-gloved hand.
