With a calamari surprise

The girls go into the changing room and change into their dashing bikinis. They head into the stalls to do it out of fear of embarrassment even though everyone there is also a girl. As they were changing, Yagyuu walks in and strips down to her swimsuit and hides her clothes so no one can find them. She then hides around a corner with the same tactic waiting until after the other girls leave the room expecting Minori to leave her clothes there.

Meanwhile......

"Awww, how are you shorter than me with bigger boobs?" Hibari wonders in jealousy.

"Idk, Minori guesses that's just how it ended up. Maybe it was Mommy's idea!" replied Minori. They begin to play with each others boobs for a little bit since they're naked and no one can see them anyway, and they both laugh since it tickles them.

"Having fun already? Oh that's it! You're going down Ms. Steal My Girl!" whispers Yagyuu not wanting to be detected while expressing her frustration. "I'll give everyone a good eye full of your assets." She says wondering which part of her to flash to everyone for now.

"Hey, maybe we can take a picture." says Minori.

"B-but we're naked! You sure this is a good idea?" asks Hibari, concerned this might come back to haunt them.

"Minori's sure we'll be fine." And so they snap a picture, or several, showing off various parts of themselves but mostly focusing on their boobs, butt and crotch area with Minori's phone. They then finally decided to put on their bikinis. They jiggle their ample breasts a little to test the bras' security and hold of their chests. Seems both are tight enough and they look in the mirror and compliment each other's style. As they leave they leave everything that isn't them or their swimsuits back at the changing room.

"Took them long enough." Yagyuu gets a nosebleed after imagining Hibari seeing her rescue her from the clutches of the evil and devious Minori. She goes inside and takes Minori's stuff out of the room and takes it somewhere where Minori couldn't find it knowing she probably will be once she's done embarrassing her in front of the whole pool.

Titties bouncing as Hibari and Minori merrily skip along to where the pool is. "You wanna just jump in and splash each other?" asks Hibari.

"Oh, would I?" Minori asks excitedly. The two young women do just that, sometimes even twirling in the water to do so. They have to readjust their tops sometimes as to prevent a wardrobe malfunction from happening. Their fun comes to a halt when....

"There you are miscreant!" Yagyuu sneaks up behind them. "What are you doing with my Hibari?"

"Your Hibari?" Hibari asks out of anger. "When are you gonna learn I'm not yours? Minori and I just wanted to play at the pool after class today. We haven't done it in awhile and it's our birthday celebration." Hibari snaps.

"Well, mostly mine, it's her Valentine's Day/Birthday gift to me." She quickly regrets mentioning that.

"Sweeping Legs!" Yagyuu calls an attack. She summons a squid that manages to catch Minori and lift her off the ground. Normally her secret ninja arts would rip others' clothes apart but this time it's making an attempt straight up rip off her clothes to expose her honkers to the world.

"She didn't even do anything Yagyuu-chan!" screams Hibari trying to make Yagyuu calm down and cease this unnecessary humiliation. "You didn't even cast a barrier! And now everyone is looking at us!"

On Yagyuu's command, her pet squid completely untied Minori's bra and flung it into her hands thus exposing Minori's beautiful breasts to the world. This normally wouldn't be a problem had it not been for the lack of a barrier being casted so no one sees this. "Release." The squid vanishes and Minori drops like a stone into the water.

"Aww now Minori's butt hurts like crazy!" Minori complains rubbing her ass. As Yagyuu seemingly sent her top into a hyperspace, probably her boobs, Minori finally noticed what was missing. "Hey, where'd my top go? Now everyone's looking at me!" She cries while covering her rack.
