Strict Mistress Nikki is wearing her short uniform, showing off her nylon clad legs and sexy red stiletto heels, her sub on the examination chair, ready for her ministrations. She starts by working on his nipples with the suction cups and nipple clamps before turning her attention to his engorged cock, using her fingers to explore his hole, placing the ball weight stretcher on and some biting rubber bands, making his hardon big and very painful. After inserting a big butt plug into his asshole, Mistress continues the exploration of his excited dick, giving him an internal and external handjob at the same time, bringing him closer and closer to orgasm but stopping each time as his examination is complete and he is left tied, teased and frustrated.
