Like everyone expected, Ana pooping her panties is something quite extraordinairy.
I guess no pantypooping lover will have a problem with Ana entering the realm of
pantypoop lovers!

People loving big bulged panties of a beautiful girl will like what Ana does.
In her first scene she pushed out a very solid, long turd which just kept growing and
growing, with lots of crackling sounds until eventually her panties started to drop down
from the weight of her huge poo.

Farting and pooping even more, Ana proceeded while holding her thong up, until she
just had to stop, otherwise her panty would be torn to pieces. (which would actually
make a nice scene)

Here are some stills from the first movieclip...
