Mistress Katherine Kink has quite the surprise planned for Her slave, who thinks he is going to be getting a sensual reward for his acts of service. However, Mistress has planned something else, showing off the locking spiked ball stretcher She recently received, showing how each turn of the wrench pushes a spike into the device - which means that the spikes are going into his ball sack!

But even this is not enough to satisfy this sadistic Mistress, as She has the slave on a stretching rack. With his arms locked overhead by one pulley, She uses the other pulley to stretch his locked balls! The slave moans in pain from his balls being severely stretched, but then Katherine begins tightening the spikes into his tender ball flesh. Once all the spikes are in, Katherine plays with his helpless balls, squeezing and busting them with Her fingers as She taunts the poor slave for ever thinking he was getting a sensual reward. Katherine coldly tells him that he is a slave and She is a Dominatrix, and it is his place to always suffer for Her amusement.

Mistress Katherine Kink's slave has been begging for an orgasm, but such things are only earned by suffering for Her amusement. Katherine makes Her slave look at the size of Her cock and mocks his pathetic penis before making him beg to take Her cock. When the slave successfully takes Her cock in his ass, Mistress rewards him by stroking his cock with her hand while still strapon fucking him.

But Katherine is not totally satisfied with his suffering just yet. She shows Her slave a Kali's Teeth Bracelet, a CBT device with multiple spikes on the inside, and then locks it onto his cock! The more excited he gets from the handjob, the more pain he has to suffer - all while still being pegged! Finally even the pain is not enough to stop the slave from begging to orgasm, which Katherine does allow. Cum gushes out of the slave's cock, only for Mistress to remind Her slave that good boys must clean up their messes. Katherine then hand feeds him his cum through his gag, making sure that he swallows every last drop.

Mistress Katherine knows that Her slave worships Her cock and loves to have it inside him, so She often tests his ability to totally submit to Her strapon. After making sure he lubes up Her cock well by making him deep throat it over and over again, Katherine begins taking his ass, pounding it deeper and deeper until She is balls deep in Her bitch. But simply taking Her cock is not enough; Katherine orders him to beg for it and plead with Her to take him as long as She wants. Katherine enjoys thrusting into Her hapless slave, knowing that he will get so excited that he will try to cum even with a cage restraining his cock and balls. Katherine counts him down from ten, ramming Her cock in deeper each time until She gives Her slave permission to cum. Sure enough, he is so excited being Her fuckhole that he still manages to cum n his cage, proving that he is truly nothing but a slave for Katherine to use as She sees fit.

While Mistress Katherine Kink is a very sadistic and demanding Mistress, She does believe that quality servitude does deserve to be rewarded - of course, the terms of that are totally up to Her. After the heavy ballbusting Her slave had just taken, Katherine was in a very rewarding mood, not only giving Her slave a handjob but also sitting right on his face! Of course, the poor slave gets so excited by the stimulation of his cock and the smell of his Mistress's ass in his face that he begs to cum several times, but Katherine cruelly keeps telling him no and makes him wait, building up his orgasm until he can no longer contain himself. As punishment for cumming without Her permission, Katherine locks the newly drained slave right back into his chastity cage.

Mistress Katherine Kink is a firm believer in keeping Her slaves in extended chastity and making them truly earn the privilege of being released and being allowed to cum by suffering for Her pleasure first. And today Katherine is in the mood to bust some nuts!

Now that Her slave has suffered enough to please Her, Mistress Katherine gives Her bitch the chance to earn a release. But She has no plans on making it easy for him. She removes his cock cage and begins to jerk his tiny cock all while making fun of how tiny it is, especially compared to Her cock. She is honestly curious if this slave can actually produce any cum from such tiny testicles as She squeezes them harder and harder, making Her poor slave suffer even more.

Mistress Katherine is ready to take Her slave's ass with Her strapon, but first he has to humiliate himself for Her amusement by sucking on the huge cock first. Katherine repeatedly scolds him and slaps him in the face for his lackluster effort, reminding him that She is going to plunge Her cock into his ass balls deep, so he had better get every last bit of it wet.

Mistress Katherine Kink has had Her slave suffering in chastity for over a month, so She decides to give him a chance to earn an orgasm. But to do so, he will have to please his very sadistic Mistress who loves using Her beautiful body to tease Her hapless slaves and then punish the poor bitches for getting overly excited - as if they had any other choice!
