Denial!
Submission and domination
This is your time to shine.
Your goal is to frustrate, tease amd punish him into a prolonged Denial!
The day you start, you will make him plug up and eat you out for as long as you like. When you are finished, and don't want more orgasms, then just tell him, and say that "We're finished for today.
The next day you give him head until the point where he begs to cum. Ask him if he will eat the entire load? Yes? Well, you don't care. NO CUM today
Next day keep it up. Plug up, and tell him to clean, fix or go shop something. Make him wear the plug for the evening. At the end of the night tell him to drop his pants. Give him another round of head...
How crazy is he now?? You decide how long to prolong this. a week? ok!
only one day? ok.
You decide.
However, if he doesn't last as long as you would like, then make sure you punish him.
So this step you can alter as you see fit. The goal is to make him submit, and to experience how horrible you can be! ;)
When he is done, its time for the Finals...
