The preview vid showed no arse plunderin. The only anal scene I am aware of that Dillon has done is "Let's Try Anal." Shortly after the "Let's Try Anal" scene came out, I sent a message to her facebook page and she (or whoever actually runs her facebook page) replied it was unlikely she would do another anal scene.
Now, this could be a scene that Teem Skeet sat on, because in the most recent stuff I have seen Dillon in, she looks almost freakishly skinny to the point, I think she has even lost a cup size on her boobs. Her first scenes she was easily a solid C cup, but the more recent stuff I have seen of Dillon, she looks she might be a B cup now probably due to the weight loss.
The preview vid, her breasts look like they are at C cup level.
