Confined to her cell, the prisoner's eyes widen in panic as she feels the warm, familiar pressure building in her lower abdomen. She clenches her thighs together, her jeans tightening around her legs as she tries to hold back the flood. Her breaths come in short, sharp gasps, her body contorting as she fights the urge to release. The toilet seems miles away, and her guard's stern gaze offers no sympathy. As her bladder reaches its breaking point, the prisoner's struggle becomes a race against time and the limits of her control.
