By getting down to business of course

"Hello there, ladies," you begin as the pair eye you up. "My name is John Doe, and I'm here to talk about.. Uh.. An important university matter. But I thought we could do it naked, and maybe get to know each other's bodies. Does that sound alright?"

The redhead looks stunned, raising her eyebrows. "Well, you certainly have a lot of confidence."

You're just beginning to pull down your boxers when the student speaks up. "Oh, well I should definitely get going anyway. I'll come back later..." she says worriedly; it looks like she thinks you were only addressing the secretary!

"Actually, I'm here for both of you."

"Oh, of course... I thought you were talking to her, and..." She hesitates a moment before blurting out the rest. "Well, you see, I was just nervous that people would see us through the glass, and... And my friends would be grossed out, and my parents would stop helping me pay for--"

"Hey, hey, it's alright. Calm down."

"Okay... Okay, yeah, I'm calm," she replies, slowing her breathing almost instantly. "Sorry."

It's always interesting to see how different people react to your new power... Some are slutty and some are timid, but they all obey in the end.

"But um... People will see us from here, and I've never done this before... I mean, I had a boyfriend, but we never went all the way, and.. And.."

"Look, all that matters is that I asked you, right? Don't worry about the rest," you say in a soothing tone. You could just tell her to relay what you told her, but it kind of turned you on that she was so inexperienced.

"Of course, of course... Sorry, I don't mean to act all flustered," she says with a sheepish smile.

Removing your boxers and shirt, you grab an extra chair and sit down next to the girl. As you watch she slips her sweater off, and the secretary begins to do the same.
