She gets all of her privates exposed to the whole class.

"ughhh..., ouch, that hurt", muttered Mercedes on the floor as she rubbed her head in pain due to the fall. "I really should be more careful", she exclamed to herself as she tried to get up, only to see the faces of everyone in the class pointing down directly to her lower half.

"ehh...m-mercie...", commented Annette worried and concerned to her in the ear.

"emm...yes...?", replied Mercedes uncertainly, desperately hoping that that what her friend was about to say to her, wasn't the thing she was fearing the most.

"...Y-You s-should really close your l-legs right now...", said Annette to Mercedes as she tried to explain her "position" in the least offensive terms possible. But it was all for nothing, for Mercedes cried loud once she knew what that meant.

"NO, This can't be...!!", was all that Mercedes could think right now in this moment, as she saw none other than her blonde pubes, and her pink womanhood completely exposed to the eyes of her peers, upon which, she immediately closed her legs hard, but it was too late, for everyone in the room knew what they had just saw.

"Wow, she really isn't wearing panties today", exclamed a curious student.

"I knew that she lying by the looks of her face", said someone in response.

"Wow, look at that thing", commented a perveted male student.

"Either she's a complete ditz, or a complete pervert for walking around like this", joked a female classmate.

"Do i need to explain to you of committing public indecency in this holy institution of learning. Miss von Martritz ?", lectured Hanneman as he threatened to have her suspended or worse.

"eh...eh..., i-i need to do something!!", Mercedes whispered to herself as she tried to think a way out of this very tricky situation.
