I not only push this slave's limits, I bulldoze them; but when a male slave has been locked in steel chastity for as long as this bitch, their sexual desperation leads them to agree to all sorts of horrific procedures.
As payment for being allowed a day out of his cock cage, my slave will be taking bigger and bigger sounds down his urethra, even glass ones, as I stretch and fuck his cockhole harder and larger than he's ever been stretched and pounded before.
