Yes, she attempts to escape

In a quick smooth and sudden motion she unclipped her leash and began running with the collar still around her neck. She managed to catch her guides off guard. Julie ran for a dense part of the crowd, but tripped on the loose leash. She crashed unto the sand, and the others quickly caught her.

"Man, that has to be fate right? Trying to cheat three times? You clearly still have not learned your lesson." One of the boys said with feigned disappointment.

Julie had no defence. She could only anticipate what was in store next. They held her tightly while they discussed.

"Ahh I know what's going on here." Someone said. "Our little cheat here just likes getting punished. She's maybe too embarrassed to admit it. She's obviously into public (very public) stuff."

"No guys, please this is too far! Let me go!" Julie begged.

"We can read between the lines. Let's give you what you really want."

"No it's okay, I had enough really!" Julie tried.

She was not lying either. She had had more than enough humiliation for a day. They did not give up, however. Instead, they dragged her along to a table in the centre of the boulevard. They brought along some intrigued onlookers too, curiously watching the scene unfold. They took off her collar. Julie was surprised a little, standing there with crossed legs and hands on her tits.

"For your crimes against the party code, you have to masturbate - to completion - right here and now."

Julie stuttered a response. She was surrounded, no way out. They almost pushed her unto the table. She sat down, two dozen faces staring back at her. She was frozen for a moment, thinking of an escape. The only thing she could think of was faking it, but was that any better than just cumming for real? She slowly placed her hand between her closed legs and on her pussy, her fingers burrowing to touch her clit. She was soaking wet already.

Julie began to rub. Her eyes were firmly shut, but she could hear the murmurs of the audience. She placed on hand on her breast. Her body was quivering. Every touch was ectasy. She slowly opened her legs a little, and began rubbing harder. She took short, trembling breaths. The thought of all those people looking at her brought her only more pleasure now. The humiliation she still felt only adding to her arousal. She felt small, ****, exposed, used. Her legs opened fully. Her finger slid into her, then another. She cupped her hand and fingered herself with increasing intensity. She opened her eyes. Everyone was staring at her. Boys were filming her on their phones. Her eyes welled up with tears of pleasure and embarrassment. A torrent of sensation overwhelmed her. She lifted her legs up, her bare feet in the air. Someone touched her, held her leg up. Her intensity increased. She began moaning, softly first, then louder. She tried to stifle it but couldn't. Finally, she began to climax. Her body shuddered violently as she came with a wet, squirting orgasm. She convulsed six times, gushing each time. She made eye contact with so many people before her eyes rolled back.

She sat there trembling for minutes afterwards. The words of her "guides" passing into one ear and out the other. Slowly she returned to the real world. With it came overwhelming embarrassment. She closed her quivering legs and hid her red blushing face. She stood up, and rushed away from the people.

She wandered aimlessly before she came to her senses. This was crazy! She had to get back to her hostel right fucking now. What had she just done? It was the orgasm of a lifetime, but in front of all those people and cameras? If someone she knew discovered this... or if the videos reached her hometown... oh god.

Julie, still naked and weak, returned to a familiar area. The hostel was not far.
