Luke must submit to the new Alpha, Elias. He does it for the pack, but that doesn't mean he won't take pleasure in it for his own sake. The old Alpha is dead, and his son, Elias, is rising to take his place. He was his father's choice, but a symbolic act of dominance must solidify his claim and ensure the submission of his people. Luke is chosen to act as proxy for the entire pack. He's wanted Elias for years, but this isn't about him or his desires. He must submit himself for the first time to Elias, for the pack, for a cohesive community, and for peace. That doesn't mean he won't take pleasure in their coupling for his own sake.
