Where does it all go?

When this video started, I was 100% sure that this girl could not deep-throat a dildo of that size... It has basically the mass of her own head. But she friggin' does it! How, I have no idea! 

And she is pretty too. She should be in porn, she could say to them: "I cost twice as much, but if you can find any man who is too big for me to deep-throat, it is free."
