What the prince slipped Cinderella was not a slipper

Cinderella, with the help of her "fairy" godmother, is granted heightened sexual prowess to win over Prince Charming. After a blindfolded orgy at the royal castle, the nerdy Prince must sleep with every willing woman in his kingdom until he finds that one, mysterious lover who so "stood out" on the night of the sex Ball.
