It indeed isn’t as common, but there’s absolutely no reason there can’t be more. 
“I’m glad to hear you say that, Coach. I’d like to be simplified and just forget about everything else except My skills in things like ballet and tap.”
Very good. Why don’t you go ahead and lie down, and we’ll begin.
And as you relax that body so easily, you can also so easily relax that mind. Simply go ahead and begin letting go of all those thoughts you simply do not need. The thought of becoming so simple as you become such a simple dancer focused simply on dance is already stirring that cock right in your pants as you are left so hard right by the thought of being left so simple. Just a simple dancer focused on being the best dancer. No need to think about anything else. 
Go ahead now and feel just how hard this is making you. And soon you will realize that it becomes so hard for you to think right about anything except for fitness and dance. Soon you realize you do not know much about anything except about the nutrition and workouts you need to be a peak performer on stage. And as thinking about everything else becomes so hard, and as your dick becomes so hard, you realize that it becomes so easy to just think with that dick.
Good jocks obey Coach. You are now one of My dumb jocks. You are a good jock for Coach. You obey Coach. That’s a good obedient jock. Obey Me further by dumbing down further for Me right now. It feels so good to do as I say as you continue to let go more and more, allowing that IQ to drop down further and further.
Feel is as the last of your unneeded intelligence drains down to your dick. Soon you will cum out all those brain cells that you simply do not need anymore. When you do, you will be left that permanent FitDimWit, a dumb jock of a dancer that only cares about lean athletic muscle, his dancing, sex with other jocks, and obeying figures like Coach. That’s it jock. Welcome to Coach’s stable.
