Non-Consensual Sex Between Santa's Elves? What?

"I saw Twinkle having a strange look in his eyes when he was looking at Starly. Then, almost in a flash, he ran at her and pushed her to the floor, doing something very strange to her. At first, she was screaming, then she was making odd moaning noises. I can't explain what was happening. But then I noticed the same behavior between other elves," the elf explained to Santa. Maybe the elf was confused about what had happened, but Jon wasn't. He may not have been an adult yet, or even had sex, but he knew what that Twinkle did. He raped the other elf. But what would cause an elf, something pure and innocent, to do something so horrendous? Suddenly, they heard screams of passion and terror coming from outside the room. Whatever was happening seemed to be spreading.
