You’ve been masturbating without eating your cum for a long time, even though you told me otherwise. I can’t stand liars, and so you’re going to pay the price.
Don’t worry, though, you’ll still be allowed to cum. In fact, you’re going to be cumming A LOT! And yes, you’re going to be cleaning up your cum every single time. You’re okay with my “punishment,” because you don’t really hate eating cum. You’re just really lazy and self-indulgent. You’re quite happy to jerk off and eat your cum for Mistress.
You and I meet for our usual weekly session. You’re as excited as always, as if you haven’t been cheating and lying all this time. I tie you up and begin stroking your cock. You lay back and beg for mercy, even though you’re not in any kind of agony whatsoever.
