Surrender your panties

You look down at your dress. The hem is short, just above mid-thigh, which could make things easier. But of course, once your panties are off, that just threatens to flash your fellow partygoers even more readily.

Why can’t she just believe you!? Does everyone in the god-forsaken town just want to play perverted games? You control your tone before speaking, trying to sound as serious as possible.
“I’m not doing it here, that’s insane.”

“Oh, you’ll be fine. I’ll keep watch for you, just don’t be too obvious about it.”

You roll your eyes.
“Right, thanks for the advice.”

You look around. She’s probably right. Everyone is paying attention to themselves, and you could pull them off quick.

“Go on.”

“Calm down, okay? You’re gonna make somebody suspicious,” you whisper.

You walk over to a table, wanting a bit of cover. Then you hike up your skirt and grab the bottom of your panties, alternating pulling the left and right sides down until they’re totally free, maybe 5 seconds total, no flashing as far as you can tell. Of course, it felt way longer.

You bend down, pick them up, and then take a few seconds to breathe. Chin down, still feeling very self-conscious, you put them in the girl’s hands.

“Awesome.” She sounds legitimately impressed.

You timidly meet her eyes and her look makes a bit of fire run through you. You’re starting to think she has a bit of a crush on you.

“You know who has to see these, right? Hey Theo!”

“Oh my god, why don’t you show him yours? You two are like clueless star-crossed lovers.”

“Yeah, we tried that and it… didn’t work out. Much more fun to do shit like this.”

The energetic boy trots back over, and the girl shows him your panties, holding them taut, high in the air where anybody could see them.

“Guess whose these are!”

“No way, haha!”

“She took them off right here.”

He looks around. “Nobody saw you? I mean, I already know what you look like under those, but that’s pretty daring.”

“Yeah, don’t remind me, buddy.”

The girl hands them over to Theo, which you are none too happy about.

“Hey wait, I need those back!”

“Why? You’re doing fine without them right now.”

You grumble. At least Theo has the decency not to sniff them or something gross.

Surprisingly, the party goes fine. Your modesty stays completely intact, at least as far as you know.

Then, once you get home, you decide you have to take a look at your subreddit. Logging on, you gasp as you view the very first post. Facing you is none other than your very own black panties from tonight, along with a picture of you from the party. That bastard! You surmise that it was probably the girl (whose name you still don’t know, dammit), rather than Theo.

You flip through a few more posts of your naked body around town before getting a bit queasy and deciding this isn't helping your situation. None of them even had the decency of obscuring your face, meaning anyone with a reasonably-large database could know your identity by now. Clearly the consequences of the games and assignments are starting to catch up with you, but you have no idea how to fix things.

Hell, it’ll only get worse from here, you think somberly.
