Ask her about the school.

"You are a visitor here, I imagine?" she inquires thoughtfully.

"Yes, I... well I'm enrolled at a college and I was assigned this school to write a report about."

She chuckles, "Oh really? That's fascinating."

"Umm, is it?" you say awkwardly, "Anyway, are you a student here?"

"In a way," she drawls, "I am."

Her stare is very attractive. She's entirely focused on you. You've never had this kind of attention before. It's actually making you uncomfortable.

"Can I ask you some questions then? It'll help me write my report."

"I can do better than that. How about a tour? I can give you a complete one," she licks her lips subtilely, "The whole campus."

"Really? You can do that? Won't you get in trouble? Shouldn't you be in class?"

She shakes her head slightly, "No, I'm sure I'll be rewarded for my initiative, actually. This school is... like that."

Oh, well, who are you to refuse such an enchanting woman? She seems knowledgeable and you could get an important perspective.
