She asks a stranger for help

Julie felt her nerves build again. She had to **** herself into exposing herself again. That was somehow even harder than being ****. She was totally restrained, entirely at the mercy of however ran into her. Her nipples were hard too, much to her embarrassment. Her pussy even glistened from her shameful arousal. Yet, what choice did she have? She had to get these ropes off. She carefully shimmied to the edge of the alley, looking into the busy boulevard.

There was no way she could just attract one person. Everybody was in a small group, or a couple at the very least. She had to be very careful to just get the attention of one such group, rather than a hole bunch. She sat crouched behind a bush for a long time, too nervous to make her move. She tried to wait for a calm moment, but the crowd of people just kept coming.

Finally, she worked up the courage to call out to someone. A couple walking by heard her and curiously looked in her direction.

"Uhm... it is going to look a little weird, but I need some help."

"Who... oh! There you are." The girl said, just spotting Julie's head poking out.

"What's up?" The boy asked.

"Well... I am a little bit trapped. Sort of."

The couple walked into the alleyway. The girl gasped a little and covered her mouth with her hands when she saw Julie. The boy politely averted his gaze, although he quickly started peeking. Julie retreated a little bit into the alleyway, inadvertently exposing more of her body.

"Could you pleaaase untie me?"

The couple nodded and followed her back to the little square at the end of the alley. Julie could only stand there as they looked her up and down, everything on display.

"Did you lose a dare or something?"

"Yes! Something like that... Could you please get these ropes off?"

The couple looked at each other and thought for a moment. Luckily, it seemed they agreed to let her out of her bondage. They both went behind her, and the touch of their hands on her skin gave her goosebumps. Her nipples grew rockhard, and she was pretty sure her helpers noticed too. Nevertheless, she felt the ropes loosen and soon fall to the ground. She quickly turned around and covered herself up with her hands as best she could. She thanked the couple heartily.

"Good luck with the rest of your dare, I guess." The girl said, eager to get away from this naked girl that was enamouring her boyfriend. He wanted to say something, but she pulled him away, leaving Julie alone again. The ordeal had left her super super horny, and now with some relative privacy and the freedom to move her arms, she couldn't help but touch herself. First her breasts and sensitive nipples begged to be touch, then her wet pussy. It felt amazing, but she was to afraid to continue out here. She had to get back to her hostel, find some clothes, and then only then she could let herself cum somewhere safe. But how could she do any of that from here?
