Setting the baseline

The two older girls looked at each other, then at Sara, not sure how to answer.

"Ah, I see. Well, I have a quiz with me to determine your level of understanding." Sara said, removing a couple pages from her bag.

Placing them on the table she slid them over to two girls.

"Wait, a test? I thought you'd give us some tips or tricks?" Mary whined.

"Yeah, we hired you so we wouldn't have to worry about tests." Susie added.

"Don't worry, it's not worth anything except for me to understand where you might be struggling." Sara explained.

"I still don't know...seems like a waste of time. We don't know anything." Susie said.

"I know! What if we made it more interesting?" Mary chimed in.

"How so?" Sara asked, trying to sound nervous.

"Well...how many clothing items are you wearing?" Mary asked.

Sara counted in her head before answering, "Three, plus shoes and socks."

"Shoes can count as a single item, and shoes as well. Now, what I have in mine, since I see ten questions, is that for every wrote answer that both me AND Susie get correct, we remove an article of clothing from you, and you have to stay like that until our time is up." Mary smiled.

"But...that means I have 5 items. I'll have nothing for when you get over five correct answers." Sara commented.

"Oh, don't worry. Like I said, we're not that great at it, and since we both have to get it right, I'll be impressed if we even get one right." Mary explained.

"Um...OK, sure..." Sara replied, trying to sound taken aback, despite her own full nude adventures.
