Betrayed and Inserted Love Live! School Idol Size Stories - Definitive Edition! chapter 6 by Ninten

"Oh, there you girls are. Did you get even smaller...?" Shiki's almost patronizingly calm voice startled the tiny girls hiding under a tampon.

"No duh we're smaller! I'm so over this, grow us back right now!" shouted Natsumi, nestled in Kinako's cleavage.

Shiki tilted her head. "I can't hear Natsumi's tiny voice, she's just too itty bitty. What'd she say?"

"S-she just said it's a little scary being this tiny and... she wants to grow back..." Kinako lied, too overwhelmed by the size of Shiki standing over her.

"Hmm... No, I don't think so. Not yet, anyways. The experiment has barely even begun." Shiki stated plainly. "Honestly, you two hiding under a tampon of all things just gave me an idea."

Kinako and Natsumi could only hope and pray Shiki didn't intend to do anything too outrageous with them.

As it turned out, they were wrong.


The teenage scientist lifted up her two shrunken friends and the tampon they were underneath. By her estimation, Kinako was around a quarter of an inch, while Natsumi was 1/24 of an inch. Shiki took the tampon out of its wrapper and without missing a beat, inserted Kinako (and by extension, Natsumi, still unfortunately trapped between Kinako's boobs), into the tampon.

"W-what are you doing, Shiki-chan...!? T-this is too much...!!" stuttered Kinako, unable to form the proper words for the situation she was being put through.

"You gave me an idea with your little hiding place. I'm on my period, so I'm sorry if I get a little rough. I'm not used to handling things as tiny as yourselves. You're going to be helping me out a lot though, so thank you in advance."

Trying to be as gentle as she could, Shiki inserted Kinako fully into the tampon with the tip of her finger. All the while ignoring the shrunken brunette's muffled protests, and the nearly inscrutable squeaks heard from Natsumi.

"This is fucking insane!! Does she realize what she's doing!?" angrily shouted Natsumi, hitting Kinako's boobs with her tiny fists. "I'm not getting shoved up her vag!"

Kinako meanwhile, began slightly hyperventilating after seeing how infinitesimal she was just compared to the tip of Shiki's finger.


Shiki looked at the tampon, admiring her work. Knowing two of her friends were trapped inside it, smaller than specks, sent shivers down her spine. She took a look around, making sure Mei had left and no others were on their way in. Lowering her blue panties, Shiki removed her previous tampon, having done its job and absorbed the previous day's period discharge. She tossed the used tampon into the garbage. Shiki took one final look at the unused, pure white tampon holding two of her friends' lives within it.


Was she really going to do this?
