The old slave is a particularly dirty guy. And he loves playing with pain above all else. The dominant woman grants this wish to the submissive man, who is still quite inexperienced in urethral stimulation. But the dominatrix slowly introduces the fetishist to urethral sex and the old man seems to like it a lot. The mistress repeatedly jerks off his cock and pushes the metal rod out of his urethra.
