Thinking the attraction was just a stupid crush I’d grown out of. But nothing prepares you for Caden Voss up close his voice, his hands, the way his eyes strip you naked before he’s touched a single inch of you. He fought it. Weeks of cold silences and hard stares and pretending he didn’t watch my mouth when I talked. Then one night he stopped pretending. Now he has me bent over his desk every chance he gets, hand wrapped in my hair, whispering filthy things against my skin that make me forget my own name. He knows exactly how to make me beg. Exactly how to stretch me open and fill me so deep I’m sobbing into the pillow trying not to wake the whole house. It’s wrong. It’s filthy. It’s the most alive I’ve ever felt. And I don’t want him to stop. Not even a little.
