Class front

Mrs. Maxwell was not going to let Vanessa's late arrival slip by, Vanessa was standing in the middle of the class, all the students' eyes were on her, Vanessa blushed, then Mrs. Maxwell spoke, "Ms. Ilyna, I have told you before that tardiness is not tolerated, would you tell me why are you late?!"

"I... I slept in" said Vanessa who couldn't think of a lie quickly enough.

"so you are telling me that you just slept in, and you think that's an excuse?!"

"uhh, I didn't-"

"enough, you are an irresponsible person, I have expected you to mature a little bit before your graduation but I can see it was my mistake, now stand against the blackboard facing your companions, you'll stay like that for the whole class"

"b-but-"

"now!"

Vanessa was shocked, not just from the fact that the teacher was scolding her so harshly in front of all the class, anyways Vanessa obeyed and went to stand against the blackboard facing everyone.

A thing that caught everyone's attention instantly was the shortness of Vanessa's dress, it was barely bellow her crotch level, it was the first time Vanessa was seen wearing something so short and her classmates were all looking at her, she felt very embarrassed and wanted to cover herself, she had not even realized that her dress had shrunk.

Vanessa was blushing, Mrs. Maxwell continued her class.

The students at first tried not to put much attention O Vanessa but soon they started to notice a long thread going all the way out of the classroom was unraveling slowly like being pulled from the outside.

One of the girls noticed that the thread was coming out of the dress of the girl in the blackboard and she told her friends, they turned their heads and saw the long string coming out of Vanessa's dress, it seemed a very interesting thing.

The thread suddenly started to unravel a lot faster, revealing more and more of Vanessa, a moment later there started to be gasps and expressions of shock, the thread had unraveled a lot revealing what Vanessa was wearing under her dress, and it was nothing.

In her morning haste Vanessa had forgotten to put on panties so when the dress unraveled all the way above her crotch level a gasp came from the whole class.

Vanessa was confused by her companions expressions, still unaware of the fact that her dress was destroyed and was showing her pussy to everyone, then a girl pointed at her crotch, Vanessa followed her finger and saw her pussy and gasped, she had been seen bottomless by the whole class, she blushed and tried to cover her vagina tugging her dress, but it was completely useless, it was not long enough, seeing how futile it was she gave up and covered with her hands, Then the class erupted with a roar of laughter, Vanessa was mortified, and Mrs. Maxwell was not amused, she was not sure to something about this.
