I suspect this is a picture of Maria Lapiedra
Although I don't yet have enough data points to be sure.

See the nipple asymmetry in boobpedia?
I think that is why we see no areola on the far nipple
And the general navel shape checks out
I started using Yandex reverse image search
And then took a high res image to tineye.com
Lots of reviewing images and Maria seems to fit
