Mistress Nikki always enjoys urethral sounding, and today is no exception! The slave is keen to earn himself an orgasm, having not had one for a long time, and Nikki wants him to gain his release by enduring an intense sounding with some of her favourite items. The length and width of some of the sounds in this clip is cock-achingly huge, and that's before Nikki starts pushing them in four at a time! Any orgasm is guaranteed to be painful - and plugged tightly by a nice thick rod!
