This is how it really happened.
He approached her slowly. With each step his confidence in his effort to love, to possess, to continually marvel at her perfection grew. This was his quest, his reward. As a prince, he was entitled to her. Indeed, no-one else had even searched for her, and now he would claim her love forever.
He leaned over her and gently lowered his face until his lips ever so lightly touched hers, and he waited for the first blush of his true love to overwhelm them both. Nothing happened. If anything her lips were cold. Not even a tingle. Frantically, he kissed her again with much more fervor. Now there was a tingle. His body, from forehead to toes was awash in pins and needles. Not exactly what he had expected but certainly unique.
He felt her lovely white arms encircling his back. He found himself floating in the air with his beloved and then she turned him and gently lowered him to her bed.
The prince was enthralled. This was indeed not expected, but he was delighted with his princess. In spite of his deep feelings for her, his body felt incredibly heavy, and he was so very sleepy. Perhaps a short nap would revitalize him.
The princess softly kissed him on the lips exiting the room.
Moral: Spells are never broken. They are transferred willingly.
