The bell rings; the door opens...

The loud ringing of the bell made Anna wince; she was startled so much that she slipped a little further down, eliciting another moan, louder than before. She couldn't believe that that much time had passed. Still, she wouldn't stop now. She already commited to skipping a few classes, one or two more wouldn't make a difference, as long as she got to see this adventure through to the end.

Now, though, she would have to make an effort to keep her voice down. With the halls being full of students for the next five minutes, it wasn't impossible that someone would hear her.

But no worries. Nobody would come in here. It didn't look like anybody had been here for quite some time; at least nobody had dusted off, or used the desks.

So Anna continued to lose herself in the pleasurable sensations of penetrating herself with the dildo. She did hear the shuffling feet and voices outside, but knew to ignore them, as they couldn't possibly be any reason for alarm.

The turning of a key, though, was a reason for alarm. No, not alarm, it was a reason for complete panic!

Anna's immediate reaction, though, was denial. There was no way, absolutely no way this could be happening, right? So instead of bolting for the storage room door like a madwoman, Anna stood there like a statue, her gaze fixed on the door. Several agonizing seconds passed. She was almost ready to breath a sigh of relief - and pleasure - thinking that she only imagined the sound of the key.

Then, the door opened.

Her breathing just stopped. If she didn't know any better, she would think her heart stopped as well.
