The safe way - up a floor

A few students in a classroom - where she had mostly been sat down - was one thing, but showing the entire student body her entire student body was another thing entirely. She decided to take the slower but safer option of going up to the next floor.

She knew it would cost her time, however, so she decided to be quick about it. With the phone still clenched in her fist she dashed up the stairs as fast as she could and ignored the rapid bouncing of her bared breasts. Unlike before she couldn't pin them down with her arm as she needed that arm to be pumping for maximum speed. She reached the next floor. A pair of fire doors separated the stairwell from the hallway beyond, and there were another pair at the far end. In between them were four classrooms although with lunch still underway she felt confident that they were empty. Anna pushed open the fire door while being careful not to throw it open and then sprinted as fast as she could to the other end. Her arms pumped frantically at her sides and her bare feet flew over the cold hardwood floor. Her breasts swung wildly but she ignored the discomfort and focused solely on the door. She soon reached it and, with significantly less care, threw them open. They crashed against the wall as she descended the stairs two at a time. At the bottom she found herself on the other side of the main hall, and the noise of the other students was too close and loud for her comfort. Without waiting to check if she'd been seen, she opened the door leading out of the main hall and found herself in a deserted corridor. She was breathing heavily now, her heart was pumping, and she could feel sweat starting to form all over her body. She made her way over to the band room and opened the door cautiously; she had no idea how many people had taken her clothes, after all, and she wanted to know who was inside before she went in.

She poked her head into the room. It was empty. That was... a bad sign. She'd been expecting somebody, at least. She opened the door and stepped inside. The band room consisted of a dozen or so chairs with music stands before each of them, and they all faced a chalkboard at the front of the room. An open archway led to a smaller storage room which Anna knew contained instruments. The rest of the main room was taken up with a dozen black storage boxes which were used whenever the band had to transport their instruments to another location. Height-wise they were between Anna's knee and hip, and were three foot by four foot wide. Anna was instantly drawn to them as, resting on top of one of them, was some sort of clothing. Not a lot of it, though. She picked it up and realised it was two bras - a white one (her own), and a larger black one which presumably belonged to Claire. The phone buzzed, and she almost jumped out of her skin with fright. She flipped it open and read the new message.

Band practice starts when the bell rings. This is the only unlocked box. You girls had better 69 inside it and stay hidden.

Almost as soon as she finished reading it the bell rang, indicating that lunch was over and that class was due to begin. There was no other option. Anna opened the lid and threw both bras inside; there was no time to put hers on. With her and Claire it would have been a tight fit, and like the note suggested they would have been very intimate with one another. Alone, however, Anna fitted inside quite comfortably. She pulled the lid shut and curled up into a ball. It wasn't a moment too soon. She immediately heard the door open and the sound of her fellow students taking their seats could be heard. By now she'd caught her breath, but in the tight confines of the box every sound she made - her light breathing, the rub of her skin as she tried to make herself more comfortable - sounded incredibly loud. She waited for what felt like an eternity as the class talked amongst themselves. Then she heard a teacher's voice - a man's voice - tell them to settle down. After a few minutes the plaintive wailing of poorly played instruments began to fill the room. Anna began to panic. What if the blackmailer was in this class, and her plan was to just open the box and expose Anna to everyone? It wasn't really any worse than what she'd been through, of course, but the teacher might want to know what she was doing hiding in a box naked with her - and another girl's - bra. She could think of no rational explanation for that. The other teachers had sort of accepted her lack of clothing, but would this one?

"Excuse me, sir." A girl's voice cut in to the music. The sound of it was muffled through the box, so Anna could not identify it. The music stopped.

"Yes, what is it?" the teacher asked.

"Miss Abermoore sent me. She wanted to know if she could borrow one of your storage boxes."

Anna felt her panic rising.

"Oh?" the teacher asked. "What for?"

"She's booked the school television to show us a video, but the TV stand has gone missing. She wants to put the TV on top of one of the boxes instead."

"Well... okay then. But please ask her to be careful not to scratch it."

"Of course."

Anna heard footsteps approaching. The box suddenly moved. Although she was still in darkness, Anna could feel the box being moved by somebody pushing it; she could also hear the girl grunting as she did so. Using her sense of direction, Anna felt the box moving towards the classroom door. Her weight shifted to the left which told her they were turning right, back towards the main hall.

"Hey in there." the girl's voice said. "Don't open the lid. I need to disorientate you."

Before Anna could ask what she meant the box was suddenly spinning around. She wasn't thrown around - lying on the bottom of the box, her centre of gravity was too low to move her - but she quickly lost her sense of direction as the box was spun to and fro. After a few seconds it stopped, and she felt herself being pushed once again. Now, however, she had no idea where she was going. She clasped the phone and the bras against her chest protectively.

After a few minutes the movement stopped. "Don't open the lid." the girl repeated. "Wait for the text."

Anna could hear the girl's footsteps retreating, and once again she was left alone in the darkness. There didn't seem to be any sounds coming from outside. That didn't mean anything, however. She could be outside of the school, or in the back of a classroom full of students quietly watching the television, or anywhere really. She gave a jump of fright as the phone buzzed and lit up the darkness. She flipped it open and read the message.

Okay, step out now.

Anna cautiously opened the lid and sat up.
