Just as Killian didn't like the idea of sharing his mate, Elena, Xavier also hated the idea.
Although Xavier had never thought so far about it, just smelling the arousal of his mate in the air, made him almost lose his mind and it was at that moment he realized he would never be able to share Elena
Elena's arousal was the most beautiful scent that had ever crossed his nose and he wanted to be the only one to have a scent of it.
The thought of Killian touching what was already his literally set Xavier on fire. He didn't even realize how possessive he sounded but knew he wanted nothing but to stop Killian from touching Elena.
Xavier was about to break the door down when his wolf Zuko voiced out. "Break the door and she'll hate you forever."
Xavier let out a low rumble, annoyed by what Zuko had just said and how he suddenly popped out.
