You've been a good slut, done your expected number of edges each day, done your daily throat practice, taken your daily pain in your tits/cunt/ass, watched your daily conditioning porn session, taken care of your owner's needs, kept yourself available to use, kept his balls drained, etc. and followed all your rules. So at the end of the period of time, you have earned your orgasm, right?
WRONG
Sluts do not *earn* an orgasm, but merely the OPPORTUNITY to orgasm.
This can manifest in a couple of different ways. I might allow you to roll the dice and if it's odd, you get one option, even you get another option.
One of my favorite options is I have you lay on your back with your head handing off the edge of the bed with your hands behind/under your back. I'll come slide my cock into your throat. You will begin to suck. While you work my cock, I pick up a belt and make sure your legs are spread apart. I then begin to grope and slap your tits and belt your cunt. Not heavy; not to draw blood or anything. Just solid slaps. I aim for enough contact to sting, but not so much it's all pain - you should actually still feel a bit of pleasure from it.
And you have permission to cum at any point you can. I'll continue to use your throat and moderately belt your cunt, sporadically squeezing/slapping your tits. This is your opportunity. You can cum as much and as many times as you can during this time. However, when I am finished using your throat and cum, the belting stops and your opportunity is over.
Then you will have to wait and follow your rules until the next opportunity to attempt to cum. You'll be amazed at how quickly you'll find yourself able to cum from being belted in the cunt after several cycles of this.
So remember you don't "deserve" to cum. You haven't "earned" an orgasm. You may earn the opportunity and if you're desperate and needy enough, you might just pull it off. Then back to denial. And if not, then I guess you weren't really as needy as you claimed, were you?
