What is your favorite kink? (Patreon)

While the story of Radiant is already set in stone and I'm far too stubborn to change it... we love hearing feedback from our loyal patrons: it helps us to grow and improve ourselves as creators. One thing I'm curious about, since this is a newish game that is attracting a LOT of people... what is your all-time favorite kink (that is included inside the game)? Which one is/was the biggest draw for you as a player?

Only one answer per person/you can only choose one, so pick your poison and do so wisely! 

You can optionally tell us why or specify "others" in the reply section. Oh, and don't worry... if you notice there are certain kinks that you don't like on this list: the vast majority are completely and totally optional.
