Wait, why do you have these?

Jessica thinks about Amy's offer for a moment, realizing it was a bit strange for her friend to bring spare panties to school in the first place. "Why do you have these?" She asks casually, causing her friend to blush.

"Uhhmm.. well, actually.." Amy starts, feeling embarrassed. "I don't really like using the school toilets. Or public bathrooms, in general, so.. I usually try and hold it until I get home, but.. somedays I don't make it, so I bring spares to change into during my long walk back to my house," she explains.

Jessica was stunned, but it made sense once she realizes she's never seen Amy in the bathrooms. "You must have a pretty strong bladder, I'm jealous!" She jokes, trying to make her friend feel better.

"I guess I do," Amy responds. "Hadn't really thought about that.. but I don't really want you feeling jealous, so..."

"Oh nah, I was only kidding for the most part." Jessica says.

"That's good," Amy replies. "Well, uhm.. now we have that out of the way, do you still want to take me up on the offer?" She asks.
