Day 2 -
You know what would be nice? If you started thanking me for allowing you to swallow your cum. I mean, you regard it as something you do for me.
It's actually the opposite. I am allowing you to savour it and gulp it down. So today you will cum in your mouth, you can spit a bit of it out if you want to. Then kneel down, swallow and say: "Thank you Mistress Lacey, for allowing me to gulp down a hot load of man juice."
By now, you are either getting used to this, or it's turning into your favourite worst nightmare...:)
Rewards will be far greater than the effort you have to put in now. Don't stop.
