A Growing Concern

Today we engage in some Original Research. The subject of investigation is the uber-famous AV actress, Maria Yumeno (夢野まりあ). The subject, more specifically, is her boobs. According to a 2003 interview, she's always been known for her chesticular attributes, which were, at that time, touted as 37-inch, made more impressive by her thin body. We see them at separate points in their careers in the images in this paragraph.
At upper left we see Maria-chan young, frisky and pert, early in her career, which was inaugurated in 1998. To the right, Ms. Yumeno can be seen sometime mid-career, sporting a more buxom, if not entirely supernatural physique. And at lower left, we see Maria-san at her most fully-developed, in her recent DVD, Neighborhood Association Slave Wife: Maria Yumeno (Chônai-kai dorei hitozuma: Yumeno Maria - 町内会奴隷人妻　夢野まりあ; MDYD-679; April 2012). First, notice that she has become generally plumper with the passage of time. Her face is better filled-out, as are her arms. This is all to be expected of an aging star, and actually very much to my own liking, and, if I am to judge by search terms and comments, to the approval of my readers. So far so good. But, even taking into account natural expansion of the body which comes with age, I begin to suspect there have been extra-natural forces at work here. Our curiosity aroused, let us do some more research and investigate the matter further.

For more to food for thought, please contemplate the evidence presented in the two images in this paragraph. At right we see the young starlet Maria-san at an earlier stage in her career. Healthy in the bosom department, certainly, but not supernaturally endowed. However, in the image to the left we see Yumeno again in her April 2012 DVD appearance. Does anyone else notice a dramatic change in Maria's figure in the more recent image? Or are my eyes playing tricks on me?

OK. I'll stop beating about the bush and state my central thesis outright. Here's what I think: Something happened. Maria Yumeno's upper torso has expanded at a rate disproportionate to the rest of her body. If I were a religious man, I might think divine intervention had been at work here. My suspicion, however, is that human meddling is involved. Craving an explanation for this oddly location-specific growth, I went a-Googling, and found this site. It states that she had implants at her manager's recommendation, and that she was the first Japanese AV star to do so. Good move or bad move? In the eyes of the beholder, I suppose, but apparently it did create the desired positive publicity for DVD sales.
