going on a JAV site and looking up 149cm or whatever isn't too hard
and if you want porn, Bing or Yandex is definitely your best pick

there's one about a girl that ends up living in a barrel I remember seeing that was quite funny, I don't remember the code though...

honestly though, when it comes to JAVs, I like normal sized with tits more than loli sized and flat
the idea has merit, but MEATY (not fat though, you can't have so much mass that you're shapeless) WITH BOOBS is just inherently eroi vs someone tiny with a washboard chest
