Not that I know of, though I haven't checked every scene. John whatsisname the Fake Agent/Taxi guy didn't get her to do it & he's a fiend for a tongue up the bum so I'd guess it's on her list of things she's not up for. In Wonders in the Water (DDF Busty 2012) she licks Jelena Jensen out from behind for about 10 seconds but conspicuously avoids the butthole, which I would take as further evidence. She sucks balls pretty damn good tho.
