Age Progression?

Base +6, KatoMegumi418 -4

I'm not sure what's going on here either. Looks like some sort of slut, bimbo, or milf transformation. But then why the weight gain? And if it's a pregnancy transformation, why isn't she showing more? It certainly isn't an age progression. And why also only one transition? It's practically a necessity with transformation-based works to have at the bare minimum two transitions, always preferably more, so the viewer can deduce how we got from points A to C. With this we have no idea how or what happened; it's instantaneous. All that aside, the quality of the artwork is great at least.
