The game was in RPG Maker.
I recall that the woman that was corrupted was some sort of holy paladin, where her protective charms fell off because of sabotage.
You played her during the corruption sequence, but she wasn't the main character.
The good guys set up traps for her to be raped and corrupted to their side.
Apparently the "good" god was evil and the goblins good or something like that.
The only other detail I can remember was that in the last transformation the armor twisted to hold her orifices open.
