Kinjal had been well aware of what she was consenting to when she'd given him the nod, she didn't see herself taking it back so quickly. Maybe at some point, when she reached a limit she didn't quite feel like pushing even a little.
This was not it, she was finding out. There were no rules for the booths, after all. It was all about her comfort level and what she felt comfortable doing, and despite the fact that she had ethics about her job (or she did to a certain point), the gist was still to make money in the end. It helped that she might have actually been the tiniest bit turned on - less by him exactly, more by what he'd done.
"You'll know when it's not all right. Believe me." There was no doubt that she meant it, too.
