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.
