Black panties

I have been unable to find out very much about "azcra," other than that she currently lives and works in New York City and Washington, DC.
Oh, and she's a professional photographer with her own business, quite adept in creating lovely femmie poses like this one. She flaunts some truly sexy panties, displayed in archtypical form. Alas, I have no idea who the model is in this erotic and beautifully posed portrait.
PW 50 (delicious and provocative, though "azcra" could have gone for color in this pose, I believe...)
