One would have thought athletic girls like Rei and Saeko would have firmer and rounder breasts than these flabby ones.

I heard around the age of 17~18 (or 16~17) exercising heavily or over stressing oneself like too much schoolwork inhibits the production of some hormones that is responsible for how big they grow.

Which might mean girls like the ones from DOA all had breasts implants gone bad.

...Sometimes I wonder why I know so much useless information that has no use for me whatsoever.
