In this series, Corrina the cheetah decides to undergo a strict training regimen; and in a matter of months, she goes from a fairly slim girl, to one heck of a muscle-bound woman. =3
Judging by the last part of the sequence though, it looks like she ended up developing something of a belly too, along with her rippling musculature; guess she may need to cut down on her carb loading, otherwise she could end up developing quite the spare tire there. =p
