Your Library Card, Please?

Kade shows up without his card. The librarian pulls him into the back room and cuffs his wrists to the top shelf. Leather bites the edge of the desk as he’s bent forward, pants shoved down just far enough to bare his ass. She tests him first with a thin wooden ruler, each strike crisp, measured, until heat blooms across both cheeks. He jerks, curses, earns another for speaking without permission. The ruler drops. She takes his balls in her gloved hand, squeezes until his knees buckle, then rolls them against her palm like dice she already knows the numbers on. A small steel clamp snaps onto the tight skin above his cock. Every breath now costs him something extra. He keeps still. He learns. When she finally strokes him, it’s only to remind him the grip can tighten again at any second.
