"Masturbate for everyone until you climax."

"All right, class," she shouts to several swimmers in the water. "Let's get started. Is everybody ready?"

"Yeah!" they shout back.

"Awesome!"

She has no idea why she's about to do this, and by her expression, that's obvious. Her eyes show panic but her body obeys the will of your magic necklace. One hand slides down her slender stomach, and then two fingers pass beneath her skimpy bikini bottoms to brush over her lips. Her body shivers as she touches her sensitive spot.

The class looks shocked. Their eyes widen.

"Uh... What are you doing, Cindy?" asks one in the crowd.

Her fingers start to move, sliding over her pussy right in front of them all. They look to her fingers beneath her bottoms shifting up and down. Then, her other hand moves up and beneath the left cup of her bikini top. He fingers pinch the nipple--both growing firm and aroused at her touch. Both her fingers clip inside her body as she makes a beckoning gesture inside of herself. Her face burns red as her legs wobble. Each stroke causes her to quietly moan, and her eyes start to flutter.

"Is she masturbating?" asks someone.

"I think she's touching herself. That's so hot!"

Massaging her tit and her pussy, and occasionally teasing her clit, she begins to pant faster as she stands in front of the pool. She hasn't yet dove into the pool yet her thighs are looking rather wet. She moves faster and faster. She moans faster and faster. Her eyes can over the students, humiliated, but she can't stop.

"Aah... Aah! I'm going to... N-Noo!" she shouts.

Suddenly, her body tenses up. She lets out one last, loud moan before shuddering and panting hard. A climax overtakes her, right in front of everybody at this public pool.

"C-Cumming! Aaah~!"

She drops to her knees, bringing herself through the orgasm until it begins to calm. She slides her wet fingers from her bottoms, brings both hands to her thighs, and stares in shock at everybody's equal reaction. After a moment, she wobbles to her feet, and begins to bounce away back to the changing rooms, horrified at what she just did.
