Do like the thought of your throat becoming your ultimate - and preferred - pleasure center? Then this is for you as it trains you to love having that back of your throat stimulated as if it was a pussy. The language allows it to work for existing partners (be it romantic or a Master situation), though others will be encouraged to enjoy any but especially those ones that can really use their size to stimulate that throat. There's also a suggestion of practicing on a dildo as you find yourself loving to have your throat fucked more than ever.
