A eager bisexual sub, hungry to please his Mistress, takes on the challenge of honing his cock-sucking skills under her watchful, dominant eye. Starting with a strapon, he learns the art of deep-throating, gagging on the thick, veined toy as his Mistress guides him, her voice stern yet encouraging. Next, he's presented with a real cock, his first taste of another man's flesh. He tentatively licks and sucks, his Mistress's firm hand on the back of his head, pushing him deeper, urging him to take more.
