Werewolf Domination. Submissive Cat Shifter

When an Alpha Werewolf appears at their humble home, Katherine knows that he's here for Jennifer,  who is older and prettier. Jennifer isn't like her, she doesn't have the cat ears and tail that people make fun of. They quickly find out that he is not here for her sister at all. He offers her mother a lot of incentive to take her back with him, not just as his wife but as an Alpha's Mate, which means he won't be the only one to have her. What kind of hidden pleasures await the timid Cat Shifter as she follows the big bad Werewolf to his home?...
She chews on her bottom lip and make biscuits on his stomach, kneading her hands on the hard muscles there to calm herself. When that fails, she resumes mouthing at the tip of her fluffy tail. "Do you understand what I am, Katherine?" he asks apropos of nothing, breaking the silence in the car. He says her name so differently from how others say it, like there is a hidden weight and depth to her name that she doesn't know.
She nods against his chest and says a muffled, "You're a werewolf.""Alpha, " he corrects gently."Is there a difference?" she asks, curious despite herself. She unfurls from the tight ball and peers up at him through her lashes that are speckled with tears. She is still mouthing at the tip of her tail and he leans in to tug it out gently, pressing his fingers into her mouth until she can taste the salt on his fingers. "Yes, " he says, his gaze darkening.
He looks hungry and she feels like she's the only thing on the menu.
