With another brand

Under the weight of the dictionary, Sabrina's arms shook like leaves. Every muscle screamed at her, but the true pain was the total exposure. Javier and Elena remained there, just inches away from her sex, while the rest of the class watched in a morbid, deathly silence.

Professor Valdez observed her agony with a critical gaze. "The lesson is not yet complete," she declared, her voice resonating with an academic coldness that chilled the blood. "A servus marked in a hidden place can still try to conceal their shame. True submission requires a mark that is visible to anyone supervising their work".

Sabrina felt a new peak of horror. "Please, Professor, I've already understood the lesson..." she pleaded, her voice breaking from the effort and the panic.

"Silence," the professor cut her off. "You are in no position to judge what you have understood. You are the exemplum, not the student. Now, lower your arms and remove the tunic".

The dictionary fell to the floor with a dull thud that made the classroom vibrate. Sabrina, consumed by fear, crossed her arms over her chest in an instinctive gesture. "I can't! I won't do it!".

Professor Valdez did not raise her voice. She simply pulled a red ink stamp engraved with the letters "SPQR" from her desk drawer. "Either you remove the tunic voluntarily and accept the brand as part of your evaluation," she said with glacial calm, "or I will remove it myself and ensure that today's exhibition becomes a formal complaint for indecent conduct before the administration. Who do you think they will believe?".

Trapped between two nightmares, Sabrina untied the cords at her shoulders with trembling fingers. The transparent silk, already in tatters, slid down her body until it formed a pool at her feet. For the first time, she stood completely naked before the entire class. Mr. Andrews' frontal brand glowed scarlet against her pale skin, still damp from Javier's contact.

"Now," the professor ordered, pointing to the surface of her desk, "lean over the desk. The brand for a disobedient **** was often applied to the buttocks".

Trembling from head to toe, Sabrina obeyed. She leaned over the cold wood, presenting her rear to the view of everyone present. She felt the damp, cold pressure of the rubber stamp as Professor Valdez pressed it firmly against the pale flesh of her left buttock, twisting it slightly to ensure the impression.

"Elena, come closer again," the professor instructed. "Inspect the new mark. Ensure the ink has penetrated correctly."

Elena, her breathing heavy, approached her classmate's exposed buttocks. Under Valdez's imperious gaze, she extended her hand and slid a finger over the fresh letters, tracing the damp relief of the red ink and sinking it slightly between the folds of her rear intimacy to check the extent of the branding.

Sabrina buried her face in her arms on the desk, letting out a muffled sob. The humiliation was total. She was no longer just the branded girl; she was the human parchment upon which her professors wrote their absolute authority.

"There," Professor Valdez concluded, admiring her work. "The status of the res is now clear to all. Now, pick up your rags and sit down. We will finish the lesson".
