You live a simple life in a small fantasy town. You possess few talents except that of Truthsaying, the ability to magically tell if someone is lying. 

One day news arrives that the King is dead of old age and that his daughter, Princess Selena, is coming to your town for her coronation. When a person close to you gets murdered soon after, and you learn that you are the only person who can save the world from an unspecified calamity, things get rather heated.

Serving under a powerful sorceress, you are taught the ability to magically remove people's inhibitions. With this knowledge in hand and a potty-mouthed pixie in tow, you are told to prepare for the arrival of the Princess so that you can seduce her and save the world (the details of this elude you). Until then, however, you must practice. How appealing, then, that this practice means using your magic to seduce as many of the town's girls as possible. 

Life is about to become... satisfying
