Isabel exposes Mindy's.........

(chapter originally by hanskumoekk at writing.com)

Mindy noticed that she was running straight into a wall as she simply had to let go of the t-shirt to catch herself to avoid a headfirst crash. She managed to do so, but at that exact moment she felt a restraint on the back of her t-shirt as if someone was grabbing it.

Suddenly she heard Isabel laughing behind her. "Now let's see what kind of panties you're hiding!" was the last thing she heard before her eyes went wide.

"NO!!!" Mindy squealed at the moment of the pull...

***

Isabel's mind was racing with excitement. Taking **** like this felt so much better than a regular prank! Right before she pulled the shirt up, she managed to think of some versions of panties she expected to see. Green panties with a bear on the butt? Pink panties with ducks on them? A thong maybe? Gosh, that'd be embarrassing! Isabel managed to think, and then she pulled up to get her answer. And what an answer she got...

The reaction time from Mindy was a bit delayed from the shock of having her shirt pulled up, and Isabel's reaction time was also influenced by some sense of shock. Because she didn't expect this!

"Bwahahaha!" Isabel laughed out loud, attracting the attention of the other handful of girls changing with a view of where they were standing. And they also started to giggle. Because what Isabel had imagined turned out to be wrong, all of the alternatives.

Because Mindy's butt was bare. She wore no panties at all. And now she was standing with her naked rear exposed to Isabel and three or four girls in the locker room!

"Blow me away, your ass is on display!" Isabel taunted as she kept laughing and kept holding the shirt up.

***

Mindy realized what had happened, and that was something that'd never happened to her before. She was always successful with her pranks, and she had always managed to stay away from backfires. But this time, she had turned into the (bare) butt of the joke - literally!

After a few seconds of shock, she finally reacted by screaming and trying to pull her shirt down, one hand keeping the front down to shield her crotch, and one hand trying to fight Isabel's hands. Isabel fought back, which kept Mindy's bare butt on display. After just pulling the shirt for a little while, Isabel decided to up her efforts and pull the shirt all the way to Mindy's head from behind. Instead of giving her an atomic wedgie with panties, she pulled the shirt over Mindy's head, blinding her and completely exposing Mindy's back which became so much naked like this, even though she still wore her sports bra.

Mindy kept one arm holding her shirt down at the front while the other frantically tried to cover her butt crack as she screamed and caused the entire girl's locker room to come to where she was standing, blinded. At that moment, her bare ass was on display for the entire locker room, but she didn't know it!

***

Isabel ran up to the blinded Mindy and smacked her bare ass three times before she laughed even louder and put her pants on the floor right in front of her.

"Alright, here's your pants!" Isabel said as Mindy managed to unhook the t-shirt from her head so it fell back down. Her face was one of a defeated girl: Her eyes watered, but she was also angry, embarrassed, humiliated. Isabel on the other hand, felt so good putting a prankster down like that, after she ALMOST had exposed her like that earlier.

Isabel walked to her locker as she dried some sweat off with her towel. Mindy looked at her and the entire locker room, most of the girls still giggling. Mindy took her pants and ran right back into the stall without saying anything.

"Well, I guess that's how you defeat a bully! I bet we won't see her around anytime soon after that emBAREASSment!" Isabel laughed, not caring that she really made it worse for Mindy than Mindy did to her.

***

Mindy sat in the stall, as she contemplated just leaving the gym and stop doing this once and for all. She had been exposed like never before, and she couldn't take the embarrassment.

But then again..., she thought to herself. Could she just leave it like this? She couldn't just let Isabel do this to her with no retaliation!?

After some further thought, Mindy had decided...

I'm going to expose that bully of a girl before I leave!!
