Thought this fit here
From the 2015 AVN, these two are small and smaller. I don't remember their names.
^ She's the shortest but the photo proves, paraphrasing that old adage, it ain't the height of the girl in the photo that matters but the size of her tits in the photo that matter more.
Was there ever a pic that better showed the difference between small, medium and extra-extra-extra large than these three women all wearing the same style bra?
