Madame Li Ying and Mistress Ae, expert dominatrices, conduct a brutal medical fetish session. In their sterile, yet kinky domain, they examine their patient, Mr. X, with sadistic precision. Madame Li Ying's gloved hands probe his intimate areas, drawing groans as she inserts a sound into his urethra, stretching it deliciously. Mistress Ae, ever the cruel nurse, aids Madame Li, her eyes gleaming with malice as she applies clamps and inflicts CBT. The patient squirms, but the double domination keeps him in check, his tormentors' pleasure evident in their cruel smiles.
