She goes to fix the trousers

"I can't stay here like this." Sandry muttered to herself. Although she was due in class in five minutes, she held her bag over her exposed rear and hurried in the opposite direction, towards a textiles classroom.

For the first time all day she got lucky, and the classroom was empty and unlocked. Sandry ducked inside, heading towards the far wall where a line of sewing machines stood on a long desk.

She had stepped out of her shoes just inside the door, allowing her to peel off her trousers as she crossed the room so by the time she reached the machines she was carrying the garment in her hands and turning it inside it. She sat at the desk and stretched the trousers out under the foot of a sewing machine, looking over the controls.
