They leave her there

By the time the group of bullies were done, there must have been hundreds of photos taken at dozens of different angles, all of Sarah's exposed body. The naked girl could hear the others talking about how they were going to be posting them online; one was showing the others her phone, apparently one of her pictures had already gotten a thousands likes. Sarah started to cry out of humiliation, pulling helplessly against her bonds. But then, the group of girls around her began to disperse, the lot of them throwing insults her way, laughing at her tears; and then, there was only Jessica remaining, a sadistic smile on her face.

"Jessica please." Sarah cried, "Please, let me go." She begged as the bully approached her.

Jessica's hand flashed forward and grabbed one of Sarah's petite breasts. She pinched her nipple between her thumb and forefinger, twisting it in her hand and eliciting a cry of pain from Sarah.

"You'll speak when you're spoken to bitch!" Jessica ordered, screaming at Sarah's tear-stained face. She leaned in close, her eyes mere inches from Sarah's. "I'm the one who gives the orders here, understand?" She growled in a low controlling manner. "For now on you are my bitch. If I tell you to bend over, you ask how far. Understand?"

Sarah could only nod as more tears rose to her eyes, these ones from the pain of her twisted nipple. Jessica let her go and began to walk away, presumably heading back to the cabin.

"W-wait," Sarah cried out, "Aren't you going to let me go?"

Jessica turned, "I'll let you go after I've decided you've learned your lesson. Don't worry, it shouldn't be too cold tonight." She smiled and waved as she turned and abandoned Sarah there, tied to the pole as naked as the day she was born, with little hope of escape.
