Mistress Nikki is very demanding when it comes to sounding a urethra. Her helpless slave is secured in a tight bodybag in the garden and can only lie there and take it as she stretches out his peehole with a series of huge sounds. But Nikki isn't satisfied with just inserting one sound at a time - she wants to see if she can insert the full set all at once! Watch as she slides sound after sound down inside his cock and then makes him cum while they are all inserted. Then comes her most enjoyable part: removing the sounds from his post-orgasmic cock.

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.
