Whatever they can think of.

Mackenzie was still reeling from her unexpected fucking, and she had barely fully processed the situation and started to get her bearings before she felt a new pair of hands on her hips.

"If she's even half as good as that guy made it sound, this is gonna be good." the newcomer muttered. Mackenzie protested in vain against the duct tape as she heard a zipper once again.

Once again she felt a foreign warmth against her dripping sex, and again there was little she could do to prevent herself from being penetrated. Mackenzie rocked forward with the man's first vigorous thrust, powerless to do anything else. Her entire body felt warm as her newest arrival quickly set about setting a frantic pace, more energetic and frenzied than the first had been.

"Oh, fuck! He wasn't kidding!" the man groaned. "This slut is amazing!"

"Hey, come on, hurry up!" someone in the crowd protested. "Some of us want a turn!"

"Fuck you! I've got stamina and I plan to enjoy this! Besides, she's got a mouth, doesn't she?" the man roughly fucking her shot back.

Mackenzie's heart skipped a beat as she heard mutters of agreement through the crowd. On either side of her, people began to hop the railing she'd been bound to and formed a mob around her front.

Where is that damn security guard?! Mackenzie thought to herself. How much more of this can I take?
