i want to tell her never to doubt me again , never to go behind my back again , and never-ever-believe i wo n't protect her and what is hers , but i open my mouth and she looks so scared and so beautiful , panting and worried , that instead i make a low , gruff sound and crush her mouth , punishing myself with her taste , the sweet , wet taste of her , so pure and good , and how i hate that she put her beautiful mouth on that motherfucker because of her love for her sister .
