"Deep throat" is a fine art with hard science underpinning the best performances.
First, there is the physical. Like a operatic tenor, the cocksucker has to be physically and genetically predispositioned to be a performer of the highest magnitude. Like operatic tenors, Deep Throat artists are born with "good pipes". Oddly, those who have played hockey or other sports which remove the teeth at a young age are most physically able to provide the most enjoyable experience to the "audience".
Next, there is the emotional and spiritual. The cocksucker can't just "like" to suck dick. The true Deep Throat artist knows that at the deepest emotional and spiritual level that their purpose in existing during this slice of the continuum of time is to provide the extraordinary pleasure which a man receives while getting mind-blowing head. For the natural born Deep Throat artist, their own pleasure comes from making "music" with the finest "instruments" which men may grace upon their taught, wet lips. They live just to be cum-guzzlers!
Third, there is technique, practice, and skill. Cocksuckers are born every moment. The most gifted Deep Throat artists benefit from training, practice, drill, and exercise. They hone their art. Daily, if possible.
We will now take questions.
