You stand there, smiling at Emma, knowing that she can't see you. Her face is still pretty pale from the shock and confusion of the photo.

Finally you come to a decision and type a message into your phone - Unless you want the photo uploaded, you'll leave your underwear outside the library back door right now.

The message gets to Emma instantly and her eyes widen as she looks at it, you feel the shock and fear rushing off her as she runs through the options. You're a little worried that she'll refuse, but of course a nudge of your power convinces her otherwise.

You smile to yourself as you walk behind her, feeling her embarrassment and a little excitement as she finally makes it to the back door.

Again she looks like she's about to chicken out but instead she pulls open the back door and glances outside, finding the alleyway empty, and then, with a sigh, drops her panties out the door, quickly slamming it shut behind her and leaning heavily against it.
