The good girl system.

I really happened. you were transported to another world. And you even have one of those systems that gives you powerful buffs and cheats if you complete quests. You can finally life you power fantasy and explore a fantasy world. Perhaps you can even make your own harem if that what you want. but the system seems to be a bit strange.

Warning: themes of objectification or sissyfication (depending on your gender) transformation, chastity, and corrupting user.
