This game of questions and answers is really starting to irritate our Professor and he's losing his patience. He expects Valeria to admit all her mistakes and he's going to force her to do just that. Unexpectedly for her, he's gently caressing the curves of her lace bra under her blouse. Her nipples instantly erect and a blissful moan escapes her lips. The next moment, however, the moan is replaced by another scream as the Professor grabs her left nipple between his two fingers, squeezes it, and roughly pulls it forward. His voice, however, remains seductively calm as he asks her “What else is wrong, honey?"

- I.. I.. was rude, Sir... oh.. sorry.. oh.. Sir - Valeria replies between her whimpers, before another sharp pain pierces her other nipple. Now both of her nipples are the object of torture at the same time.

- Something else, dear?

Valeria is now finding it very difficult to stand upright and still as the Professor continues to manipulate her poor nipples and looks like he's going to rip them off at any moment. The pain is unbearable.

- I.. I don't know, Sir.. Stop, please... oh.. it hurts… Master, please stop that, please..

- Very well, Val. Don't worry, I'll make sure to remind you, dear. Now undress. Completely. And quickly.

With these words the Professor leaves the girl to her task and he sits down in his chair behind the desk again. With his arms crossed in front of his chest and leaning back in his chair, he watches her as she frantically undresses, leaving her clothes scattered on the floor. The next moment she stands completely naked, but tries to cover herself with her hands, while still sniffling and quietly crying. Without betraying his immense displeasure, the teacher gives her further instructions.

- Oh, don't cry, my little one. I haven't even given you a reason to cry yet. Come on, come to me - like a puppy, on all fours.

Valeria's eyes instantly open wide in shock and horror, but before she can say anything, the Professor beats her to it:

- Shhhh, puppies don't talk, do they? Come on, my sweetheart, come to me... jaff-jaff

Valeria is devastated, but she knows she has no choice and it's better not to make her situation worse. She falls to all fours and slowly and hesitantly begins to walk around the desk to get to Master P. She's lucky that it's only a few steps and she still manages to do this terrible task. However, the Professor is just beginning her humiliation. He brushes her head like a puppy and speaks to her caressingly:

- Look who's here! My little one. Well done! But puppies' tongues are always stuck out... Where is yours? Let's see it?

With tears in her eyes from the growing insult, Valeria sticks her tongue out and thinks that this can't get any worse. But she's wrong. Master P opens his desk drawer and quickly clamps her tongue with a very tight and strong clamp. Valeria tries to scream in pain and surprise, but in this situation her cry is strange and muffled. Master P laughs heartily and is genuinely amused by her predicament, as he also clamps both of her nipples with two such clamps. Valeria is now in agony. Her nipples are too small and any type of clamp is always too painful for her. This is a cruel punishment, she thinks, but she doesn't have time to feel sorry for herself, because her Master has given her further instructions. Now she has to do 10 laps of his office floor in her doggy style. She hesitates for a while, but the sharp slap on her bare bottom makes her move. Her doggy steps are slow and hesitant, and by the beginning of the third lap she is already too tired. Her knees hurt from the rough terracotta floor, but that is not the worst. Each step makes her breasts sway, as the pinches on her nipples stretch them even more due to gravity and hurt her even more. The situation with her tongue is not rosy either. Now she feels it numb, but what is worse is that now she cannot take it into her mouth, she cannot swallow, and to her deep shame, her saliva is dripping down her chin, her breasts and everywhere. Despite her strong desire to cope with the task, Valeria barely completes her third lap and she collapses on the floor next to the office door. She is simply crushed - mentally and physically.
