(For record keeping purposes, both the Prince and Princess are of whatever the age of consent plus three is in your local laws.)
Once upon a time, there was a kingdom far away that had a King, a Queen, and a Prince. The royal family found themselves distraught since the Prince refused to marry any but the most noble of princesses. He had met many so-called princesses but had always found himself unsure of the truth of their identity.
The first girl he had courted claimed to be a princess based on her pale white skin, but the Prince has learned that she powdered and made her skin up. He decided that a true princess would not feel the need to lie to prove her worth.
The next to try said she was a princess and offered as proof her cooking, but when they sat to eat the food she casually grabbed handfuls of potatoes and meat and shoved food in her mouth, and the Prince told her to leave because a true princess could not have such atrocious table manners.
Others came and tried, and the Prince was ready to give up on finding a true princess, brooding in his library on a rainy day, when he heard a servant hurry past towards the front door of the castle.
Curious who could be calling at such an hour and in such a storm, the Prince followed along, thinking to greet the guest himself and, if need be, see them off without bothering his parents.
When the servant opened the door, in the entrance hall stood a young woman, drenched to the bone and with her heaving breasts uncovered. She had clearly been running, no mean feat between her large breasts, the heeled shoes, and the uneven cobbles outside.
"Please," she was saying "please let me in. I've come so very far, and my traveling companions and I were attacked on the way here. I am the Princess of a faraway kingdom and have come to meet your prince."
The door guard offered the girl a wrap from a hook by the door, and turned to find the King and Queen, but ran into the Prince instead.
"My Lord, this young woman claims to be a Princess come to meet you. Shall I take her to your parents?"
The Prince was already somewhat smitten and, having seen so much of her body, very much hoped her story was true. "No, Jarvis. Please inform my parents of her arrival, but I would like to speak with her myself."
"Yes, my lord." The loyal manservant turns and leaves the room, off to find the King and Queen.
