A bi-sissy's initiation into femdom involves intense cock sucking training. Blindfolded, he's forced to pleasure his mistress's strap-on with his mouth, feeling every ridge and curve. She controls his head, pushing him down until he gags, then pulling him back to catch his breath. His humiliation grows as he's made to worship her cock like a good sissy, his moans muffled by the ball gag. The lesson ends with him, face covered in saliva and makeup, begging for more.
