We both love medical and cruel play. So I and Mistress Mavka decided to penetrate and stretch this slave urethra with a metal sounds! Deep sounding only will be too easy for him, so we put him gas mask and give him also a breathplay which he will remember! The biggest sound diameter was in the size of my finger! Im sure it was painful for his dick! But we are not meant only, from the pleasant part he could taste my delightful breath mixed with cigarette smoke exhaled through the gas mask tube, so he could cough with my air!
