My Alpha's Control Ended Where My First Love Began

I conscientiously perform my duties as the Luna of the Blackwood pack throughout our three years of bond. During every cycle of the full moon, my Alpha, Damon Slater, insists on personally preparing Wolf Essence Elixir for me. He claims it enables me to manage my duties as Luna with greater ease. I trust him implicitly, never doubting his words. It is only later that the shaman reveals that "the elixir" is actually Shadowmoon Drug—a forbidden drug that induces infertility. I haven't even had the chance to question him when Isabelle Turner, his lover, brazenly posts a sonogram confirming the Alpha's pup in the group chat. Damon, my Alpha, does nothing, letting Isabelle accept everyone's pledge of loyalty to her. Damon coldly reminds me that our bond serves a purely political purpose for the alliance and then aggressively questions me about what grievances I still hold. He thinks of me as merely a means to serve the alliance, a tool that can be replaced at any time. He is completely wrong about that, though.
