I realize people are quick to be the morality police, but they're just breasts. They're not becoming distractions to her stories at all, and in fact I doubt you could explain how they're distracting from her stories if you tried. It's not like they can interrupt the pacing of the story by just being there, and any and all boob jokes are slipped in without becoming a tangent. They've only been a plot point once that I can think of, and I don't see a problem with that; it's a facet of her character. Frankly, any of you calling it "distracting" or "disgusting" should just read something else. It's like complaining about Superman being so buff; if something almost entirely aesthetic like that bothers you so much, there are other comics.
