"Accidentally" Flash some student

Feeling hot and horny, you get an idea. Pulling your skirt back on, You fold the waist band a few times. You can't quite tell how short you made it while sitting, so you stand up. Looking down, you can see the bottom of your skirt is at the same height as your vagina. Half your ass must be on display behind you. Looking around, no one has looked up from their work. You start walking around the classroom.

"If anyone needs any help, just let me know." You say.

A couple students look up, but one student notices your skirt. He raises his hand. You walk over to him and bend over at the waist to lean over his desk. Staying like that, you whisper to him.

"What can I do for you?"

"u-um, y-your skirt, it's umm." he stammers.

"It's what? Is there something on it?"

As you say this, you stand up and lift the front of your skirt to look at it, but you have your eyes on him the entire time. His eyes lock onto your vagina, just a few inches from his face.

"I don't see anything..." You say as you let your skirt fall back into just barely covering your vagina from view.

The bell rings and most of the students begin leaving. A few guys stay behind, including the one in front of you.
