[Shanwu] Feng's Public Restraint Assignment 3

A shy blonde operative hides a vibrating toy inside a cardboard box, racing to achieve two hidden orgasms without being discovered by nearby passersby. When a man on a phone call approaches, she must time her climax with the device’s sudden activation, risking exposure as the administrator interferes. The tension builds as she fights to complete the public restraint mission while the box’s weight and the looming threat of discovery push her toward the edge.
