She keeps trying to free herself

She was not about to admit defeat. A lot of people had already seen her. Hell, these two guys were already staring at her sweaty bare breasts right now. She began bouncing again, slowly slicing and grinding through the thick ropes that bound her. She felt everything bounce: her ass, her perky boobs, her wet thighs. She began to sweat more and more and breathe heavily too. It became an increasingly sexual display and she was sure those boys were enjoying the lewd show.

She kept on going. Her legs were burning but she kept at it. She tried to avoid acknowledging her spectators but she could feel their eyes fixed on her. In fact, the whole thing was starting to feel really sexual to her too. Although she hated admitting it, she was getting pretty turned on. Her nipples felt sensitive, just begging to be touched. She wanted to ride something moving like this. She really really wanted to get off. But she couldn't. She was trapped in this precarious position.

At least, she was until now. Suddenly her bindings snapped, finally worn out enough from all her bouncing and grinding. She fell forward as the restraints suddenly gave way, and could only just catch herself from impacting the cobblestone. She heard the boys laughing. Embarrassed, she scrambled to her feet and undid the rest of the rope. What now!? She had not thought ahead to this moment. She was still miles away from her clothes. She did not even know how she should get back to her hostel in the city and there were whole crowds in between here and there. First things first, she had to get out of view. She ran into the alley on sore legs. She found a small passage in between some houses and rushed down it. There, at last, she found a place to hide and catch her breath for a moment.
