She keeps trying

She was not about to give up now. Julie kept bouncing up and down, rubbing the rope against the metal bar. Her tits were bouncing and her legs started getting sore. The sun was high up in the sky and it was damn hot. Pretty soon she was drenched in sweat. Still, she kept at it. She thought she could feel the ropes start to loosen. Then, she heard two voices down the alley leading right to her. She stopped her bouncing but could not do anything else to hide.

Two guys entered the square. They quickly noticed her, briefly turned back, but then let the curiosity get the better of them. Julie could feel the shame wash over her again. She was in a terribly **** position. She avoided eye contact, hoping they would go away. They didn't. Instead, they sat down on a little stone ledge across from her and took out their lunch. They started eating and having a conversation, all while staring right at her like she was on TV.

Julie stood there like that for a moment. Her face was bright red, and nothing was hidden from view. She was getting thirsty too, boiling in the hot sun. She realized she had to get out of here. But would she do it alone? Bounce herself free all while giving these guys a show? Or would she ask them for help directly?
