Things escalate after a couple days.

Aside from the catcalls that she's gotten used to over the time since she started losing her clothes on a regular basis, Luna was able to pass the rest of the day fairly normally.

The next day, it wasn't Kim, but she was able to trade her skirt to another girl in exchange for lunch, leaving her to take her later classes with her panties on display again.

As she stepped into the cafeteria on Thursday, broke once again, this time it was Kim's new boyfriend, Nick or something, that stepped up. "Still broke, Luna?" After she nodded, he continued, "I was gonna leave this to Kim, but she pointed out that with as often as you're naked, counting anything involving you as cheating would be a bit ridiculous." Luna couldn't help but blush deeply at the reminder of her frequent nudity. "Anyway, I want your shirt. Let's show off one of the few bras you've got left."

Luna blushed some more as she responded. "Uh, are you sure you don't want my skirt? Possibly my panties instead?"

After a second of confusion, followed by dawning realization, ending with a cruel grin, he was firm with her. "No Luna, if you wanna eat lunch, you're going to give me your shirt."

With that established, and Luna getting wetter by the second, she reached down and pulled her shirt off, revealing that she wasn't wearing a bra today.

Hearing a mixture of appreciative and derogatory comments from all the other students, she handed it over to Nick as she put her other arm over her exposed breasts.

"Well, so much for showing off one of your bras, but this is even better. Gimme a sec, I'll be right back with your food."

It took him a little while to get her lunch, all the while she was being stared at, topless in the middle of the cafeteria.

Afterwards she had to uncover herself to eat, and then attend her classes afterwards topless. The fact that teachers didn't give her detention for showing up in class with her tits out only served to reinforce the fact that Luna being underdressed or naked was more and more becoming the rule instead of the exception.
