a girl, 18 years old, young face, full body visible, She is positioned on all fours above a rubber mat, wrists and ankles cuffed to metal loops on the floor. Her bladder full, plug vibrating lightly inside. Denied bathroom breaks all day. Her collar reads “Discipline Tier, Liquid.” Any leak before permission results in full cleanup while still gagged and restrained. She whimpers. The permission never comes.
