Russian goddess, a verified amateur, takes charge as she unlocks her chastity slave's cage, revealing his throbbing, neglected cock. Teasingly, she strokes it before introducing him to the intense pleasure-pain of urethral sounding. With expert precision, she inserts the metal rod, inch by inch, as he groans in a mix of agony and ecstasy. She dominationally commands him to maintain eye contact, talking him through the experience, while he remains in a submissive trance, eagerly pleasing his mistress.
