Mistress Kandy and I occassionally let our slaves out of confinement on good behaviour. About once a month and only if the little bitch does everything right. Even the rewards are humiliating though: Slave has been ballbusted very hard and I know an orgasm will be very difficult and painful. We decide he must release a painful load while suffering under my ass during our countdown and eat his own cum. If he fails to cum he will wait another month before being allowed to try again...
