Yes, she drops the book and runs away

Anna took one final look around, then dashed toward the exit. At last, she reached the threshold of the door. She was home free! She felt the book slipping from her hands a little as she ran. She would need to get a better grip. However, then, suddenly, she stopped. The book! She realized the door had an alarm, and it would go off if the book was not checked out. She hesitated, absentmindedly standing still while her bare ass faced the whole library. What was she going to do? As embarrassed as she would be to be discovered totally nude except for one naughty art book, she would be so much more embarrassed if she was caught totally naked. However, there was no way she could think of to disable the alarm except actually checking out the book.

Anna knew taking the book would set off the alarm. What was she going to do about that? She briefly considered trying to check it out. There was an automated checkout kiosk, meaning she would not need to interact with a librarian. However, she decided that standing at the kiosk for as long as it took to check out a book was too risky. Who knows who might see her during that time? Aside from which, she realized she did not have a library card. After all, where would she keep it?

She stood there indecisively for several seconds. Her mind raced. She knew she had to do something, but what? She was completely exposed, and any minute now someone would discover her. She was going to get caught. She just knew it.

Then she heard footsteps behind her. She had ****. She dropped the book and took off running at top speed, without even her hands to cover her. As she sped away, she thought she heard a confused murmuring behind her, but she did not turn around to check.
