Say that you don't think you'll be able to mess yourself.

"I don't think I will be able to mess myself." You say. "What if I don't need to poop?"

"Don't worry about that." Julie reassures you. "We'll take care of that."

So you and Julie meet Kate and Tanya in the shopping centre food court. Kate looks just as nervous as you. Julie and Tanya orders marge meals for you and Kate and salads for themselves.

When you've finished eating, the four of you get up and Tanya leads the group through various women's clothing stores.

"Are you really going to go through with this?" You ask Kate when the other two are distracted.

"I don't want to." She says. "But we have ." A look of discomfort suddenly comes across her face. "Oh no."

"What?" You ask before suddenly understanding. Your stomach begins to clench. "They must have slipped us laxatives."
