She has to perform a show

"You did gymnastics, right? Why don't you give us a show? You are already on stage after all."

Lia had done gymnastics early in high school. That was like 8 years ago. She could probably do some of it but it would leave her entirely unable to cover herself up. She could not get out of this... Her classmates sat down in the front row, giddy with excitement. Lia could tell they felt as if they were getting with something illegal, a real rush. Imagine how she felt, about to perform a naked show in front of her peers.

"Go on, we don't have a lot of time."

Lia sighed, her body trembling heavily. She thought of a few moves she could still do. When she felt ready, at least as much as she could feel ready for this, she dropped the hoodie to the stage and immediately began her impromptu routine. She began with two cartwheels. They felt clumsy, imperfect, but good enough. The bad part was... everything about it. Her perky tits bouncing in front of the laughing crowd. Her legs spread wide as she turned over herself. They saw EVERYTHING. And they were not impressed either. Her face turned redder than ever as they continued to laugh at her. Even the boys laughed. She thought maybe they would be... she wasn't sure. Aroused, or something? Was she not attractive? She continued her performance. It didn't last that long. She couldn't do any more.

Her arms trembled during her final move, and then buckled. She fell flat on her back. It knocked the air out of her lungs a little. She wasn't hurt too bad, but the laughter truly erupted then. She scrambled to her feet and set off to complete this stupid dare. She ran past everyone, down the long corridor between the chairs and towards the exit.
