I've seen other pix of her over on the BBW thread where I say to myself: "Yeah, her boobs are pretty big, alright."
But in this shot, I think: "Oh my gosh! She's fucking MASSIVE!" 
Exactly so. And I love how blissful she looks. She seems entirely at peace, with herself and with the fact that she has been gifted with a bosom the size of which is almost beyond mortal ken.
An amazing, amazing shot.
