Dasha Astafieva has a super ass…we know, because we saw it a few weeks ago.  So when they do this hot bikini shoot at the Playboy Mansion, they don’t show it off.  What is up Hef?  We can tell she’s wearing a thong on those hot ass cheeks, so why not play it up a little and show that bad girl off?  Quit hiding her.  After all, she stripped her panties off on the red carpet.  We know she isn’t shy.
