Wow, she's impressive to say the less. Looking at the three videos, I'd expect she's possibly real. I mean she's weak-in-the-knees big, but she's not so big that it's beyond all reason that she could be natural. ... but then again, I'm always overly optimistic about these things.
Did I miss something in the videos? Why is it thought her name is "May Lee". Is she asian? It seems possible in the oldest video (the one that had the best shot of her face).
