Her shirt soon follows

Sandry stifled a yelp as she stiffened at the sudden stinging sensation on her exposed rear. Her chest, suddenly thrust forward, put a tremendous amount of strain on her shirt. Too much strain.

POP! POP! POP!

Three buttons around her chest suddenly snapped off and went flying across the room. Her shirt yawned open just enough to expose Sandry's black bra to any of those lucky enough to be in front of her. Sandry gave a muffled squeak and hurriedly covered her chest with her arms.

"Sandry..." Miss Lane said threateningly, "What was that?"

"Nothing!" Sandry said pleadingly, turning around to face the front of the room again.

"Lower your arms Sandry."

"But Miss..."

"NOW!"

Reluctantly, Sandry obliged. She lowered her arms and treated the rest of the class to a lovely view of her spectacular cleavage and slightly ruined shirt.

"Unbelievable! Have you no regard for a properly fitting uniform at all?!" Miss Lane shouted. She snapped her fingers, "Off with the shirt too."

Sandry hesitated for a few moments before giving in. There was simply no arguing with Miss Lane. She unbuttoned the few remaining buttons and slid the shirt off her body before handing it over to Miss Lane.

She put it with the trousers on her desk and said, "You can have that back at the end of the day too. Now, are you quite finished?"

"Y-yes, miss." Sandry muttered, standing in the middle of class wearing nothing but her bra and thong.

"Then sit down and we'll resume the lesson."
