It was Annette.

As Hanneman continued his endlessly boring lecture, Annette, just like Mercedes, began too, to slowly fall sleep out of the sheer boredom of the class. As she was sitting in the middle of the class, she had more between her and the teacher, meaning that she could take a quick nap without him noticing. And so, the normally energetic girl, carefully put her head in top of a book in her desk, and slowly closed her eyes to rest a little.

Around ten minutes later, Annette, having rested somewhat a bit, slowly opened her eyes again, for otherwise, the teacher may notice that she was not paying attention. Following that, she then decided to take a peak at what her fellow classmates were doing, just in case anything happened in that period of time.

While the rest of the students in the class were going normally, if a bit bored like her too, Annette noticed that her best friend Mercedes was sleeping in the middle of class, something of a oddity for her, for she was normally an attentive and upstanding student. However, that was not what Annette found to be shocking. Rather, it was the fact that Mercedes appeared to be wearing nothing below her skirt, for her legs were showing much skin than usual.

At first, Annette thought, that maybe it was just a product of her imagination, but not wanting to eating her head over that, she then took another peek at her, and what she saw, shock her completely, for there it was, Mercedes's sex in complete view to her, right in middle of the class!

"Oh dear Seiros, it looks like she completely forgot to wear panties, again!!, what i should do now ?", Annette thought for herself as she contemplated what was the best course of action in this situation.
