Try to find cover

The situation was just too much for her. All these naked people in her classroom, trapped here naked with them, any moment her finger accidentally brushed against her pussy it sent waves of excitement through her body.

She had to do something to change the situation. Her eyes fell on the large cupboard at the back of the room where Tim had earlier collected the lab coats. There would be more in there, and maybe what happened to the last lab coat was just a coincidence.

Her mind made up, she quickly pulled herself to her feet. She didn't look back, knowing that her body was now once again on easy display to everyone in the room, she just darted directly towards the cupboard, throwing it open and stepping inside.

She froze for a moment, pulling the door closed behind her, pleased to finally be alone. She may still be naked, but at least there was no one nearby who could actually see her. For half a second, she bought her hand back to her pussy, lightly running her fingers over her pussy lips, finally letting out the low moan that had been building for so long.

The noise was enough to snap her out of it. She couldn't do this, she had only come in here to try a lab coat, not to pleasure herself.
