Alpha's Tormented Slave Mate

My alpha tells me to come into his room to clean…
Only he has an ulterior motive for my being in his room. A woman wrapped only in a towel walked into the room from the bathroom glaring at me. She walks over to the alpha who is also wearing only a towel around his waist, standing in front of the bed in his suite. He smiles at the woman who looked at him quizzically. He shakes his head. “Don’t mind her, she is only here to clean.”
He tells her. “But you on the other hand…” He reaches out and grabs her by the waist as he removes his towel then hers, kissing her passionately as he lay her on the bed climbing on top of her.
Pain slowly grows in my chest as I gasp, grabbing my chest with my hand. Their moans as their passion grows hot and heavy for each and my pain begins to intensify as he enters her and begins to thrust.
You see the cruel Alpha is my mate and he just violated the sacred Mating bond with another she-wolf causing my pain. This is the first of many sadistic things he has planned for me. He refuses to reject me it seems to thrill him seeing my pain. He is cruel and I need to escape. I need his rejection to stop all this pain. He has his chosen luna he does not need me.
Why would the Moon Goddess give me a mate so cruel and who is this other Alpha from a neighboring pack, and why is he asking questions about me?
Follow me on this journey of pain, discovery and strength.
