Another hot lesbian title which has tribbing at both scene 3 and scene 8. Its called The Blonde Eating The Blonde, from Vivid, and is available from Hotmovies and Our Theatre.
From the video description:
They’re not dumb … it’s just hard to concentrate with a mouthful of muff! They’re blondes, they’re here and they’re queer! The muff diving doesn’t stop! It’s like a never ending fantasy of all the gorgeous lesbians you’ve ever dreamed of but better and hornier!
