Let her go forward

Nope, you're not going to sacrifice yourself to save her. Besides, it'll be fun seeing her fidgeting in front of the class, trying to keep her skirt down while writing her answer.

"Anya-san, will you answer this problem?" the teacher finally asks.

"Y-yes..." she answers.

Slowly, she rises up from her seat. And carefully she makes her way to the front of the class, taking good care of her skirt while doing so.

She takes the chalk and begins writing her answer with her right hand while her left hand is keeping the hem of her skirt down.

In the meantime, you hear some guys whispering to each other.

"Hey, don't you think Anya-san is acting weird?"

"Yeah, she's always been somewhat reserved, but she was never this reserved! Keeping her skirt down like that, like she's really afraid of flashing her panties."

"True. It's not like flashing your panties is that strange of an occurence in this school, what with the skirts being so short and all."

"And don't forget that she's been there many times before with the same short skirt. She doesn't care that she may flash her panties back then."

"Ah, this reminds me of that one time when a little wind blew from the window and lifted her skirt just enough to tease us with a glimpse of her panties. What was the color again? Blue? Teal?"

"It's teal, you moron. You don't know that Anya-san's favorite panty color is teal?"

"Why would I know about that?"

"Hmph, you really should join our Anya fanclub if you like her so much. We have compiled a list of times when she flashed her panties, complete with picture! And most of the time, she wore teal!"

"No thanks. I'm not that perverted, you see."

Ah yes, the Anya fanclub. You never really liked those bunch. You feel like they're just a bunch of creeps perving on her. A distinguished girl like her deserves better, goddamnit.

Anyway, back to the girl herself. She's still writing her answer; it's quite a long one. You notice that the window is open, which means you can easily send some wind to lift up her skirt right in front of the class. It'll be nice to see her embarrassed expression some more but perhaps it'd be too cruel to embarrass her any further. You know if they see her soaked panties, they will start rumors about her. You know how proud Anya is. She may even drop out of school if she's labelled as "the girl who wet herself".
