Accept the packet of diapers and give her solemn word as required.

"It doesn't sound like I have much of a choice," Halley shook her head, taking the packet of diapers from Tim's hand. "But this is really messed up, you know..."

"...And that's exactly the attitude you need to lose," Tim reproached her, plainly. "By the end of these next three days. So you're going to give me your word. That you're going to wear these things without a single break for that whole time; and every single natural bodily function you need to perform is going to be performed inside a diaper."

"You realise how gross that..." Halley began to protest once again, but he held up an impatient hand to silence her.

"...And you're going to change that attitude," he impressed upon her once again. "The brute **** way. By doing it until you come to terms with it. Go ahead and swear."

"Fuck," breathed Halley, without a hint of irony.

"Swear that you're going to do exactly as I say," Tim impressed impatiently.

"I swear I'll fucking do it," Halley sighed.

Great. Well, she was in it now. The only question was, how was she going to keep herself to it?
