Mistress Nikki, looking stunning in her leather and boots, wearing a massive strapon dick, enters the slave cell to use one of her lucky subs. She is soon thrusting her rubber cock into his eager mouth before bending him over and fucking through the metal bars, his cries of pleasure as his asshole is stretched wide. She then torments his nipples and then puts the milking machine on his cock, frustrating him and leaving him close to the edge.
