Kit-Knox's "Free" series presents a steamy tale of teacher-student taboo. The classroom is filled with the scent of chalk and teenage hormones as the teacher, a mature vixen, begins her lesson. She writes "hardcore" on the board, her voice sultry as she explains the terms. The students watch, entranced, as she demonstrates, her hands roaming over her body, her breath hitching as she touches herself, showing them the true meaning of their lesson. The room is filled with the sound of her pleasure, a symphony of moans and gasps, as she teaches them all about desire.
