Mistress locked and gagged her pathetic slave. She takes off a gag, but immediately she orders him to suck her cock, so his mouth can be useful somehow for a moment. To humiliate slave more, she puts her dildo on the floor and commands him to jerk off this cock. This slave can only imagine that it's his cock which he masturbates, as his penis is locked in chastity and Mistress keeps keys to his freedom on her neck. She laughs, because he is struggling a lot, he is so horny, so pitiful..
