Prod Gag Of Unknown Size
My intuition tells me this is a so-called “prod gag” that fills her mouth with a dick-shaped element. The question is: just how large and long is the dildo? Or to put it another way, how long has this woman been successfully in control of her gag reflex, and how much longer can she keep it up?
Image has been on Tumblr for at least five years; original source not known.

Looks like a nice method of deep-throat training…
