What makes this pic, like so many others by Magical Ondine, so so beautiful is that not only is the pic about the meaning and the emotions behind the sex itself, but also that Irisviel isn't *thin*-thin...she has just that perfect amount of "plumpness" to her that adds to the scene entire, all without reinforcing that damned stereotype of "thin is in."
In other words, it's beautiful both from the emotional angle and also because it shows that "bigger can be better."
