A mysterious, magical button

*Inspired by paladin's "The Button" story on mcstories.

No one really knows what it is or where it come from. But this small box with a red button on top is magical. Each time someone press this button, a small change will occur on his life, improving it. Only the person who pushed the button realized what was happening, everyone else remained unaware, unless the owner of the button shared his secret with other people. For the rest of the world, it will be as if the changes had always existed. No one could notice this item unless its owner talk about it with someone.

But there is a catch. Each time someone press the button, it will slightly corrupt them, twisting their desires. Peoples which use it get less inhibited and more depraved.
