Yes, it's magnificent, isn't it? So much more impressive than yours.
That's why you need to serve it— to worship it until it gives you the prize that will humiliate you more than anything else - a load of hot cum in your mouth.
Stick out your tongue and imagine you are licking it.
Scoop up some precum from your own cock; put it on your tongue and imagine it came from the tip of your Mistress' cock.
Now, picture your head bobbing up and down on my hard shaft as you desperately try to bring me to orgasm in your mouth.
Taste your precum again, and tell me what you need.
"I need to serve your cock. Please let me worship it."
Say it out loud and repeat it three times.
