On her knees

Before she could finish her presentation she fell on her knees. You snapped your fingers and with a single wish the shibari went from under her clothes to over. It was now holding her in the kneeling position.

"What the fuck!?" Amanda cried out. She was struggling but couldnt even move the bindings as they were conected to the ground making her stuck in place. You were the first to get up.

Before she could say anything you shoved a cloth inside Amanda’s mouth. She frowned at you as you spoke to the class.

"Now. Im sure that no one here likes amanda......" Most boys in the class nodded in aggreement. Some girls however seemed a little unsure. All it took was for you to snap your finger and they were now tied up by shibari to their chairs.
