A submissive's journey in learning to suck cock begins with a dominant femdom's strapon. The mistress, a stern professor of pleasure, introduces her student to the enormous, veined silicone phallus. The submissive, nervous but eager, takes it into their mouth, the taste of plastic and their own fear filling their senses. The mistress, relentless, guides them deeper, making them gag and choke, teaching them the art of humiliation and submission. The lesson ends with a face full of their mistress's approval, the submissive left panting and glowing with pride and shame.
