"Y-Your boobs... maybe..." Kinako's blush grew and she turned away, unable to look Shiki in her large eyes.

"I figured you'd say that. I don't blame you either." Shiki swiftly unbuttoned the top few buttons of her school uniform's white blouse and brought the tiny pair of girls closer to her imposing chest.

"Why do I feel like I should have stayed home today...?" Kinako whined.

"You dummy! I don't know if you've noticed but Shiki has one of the biggest pairs of tits in the group! Lord knows how she hides them so well, but now we're gonna be squished all day!" Natsumi barked.

"I-I never noticed, I don't pay attention to that kind of stuff!" the tiny twintailed teen cried.

"Well great, this is exactly how I wanted to spend my day. I'm not even going to be able to get any good shots smushed between her huge boobs the whole time... I guess it could be worse..."

"D-don't worry, Natsumi, I'll keep you safe. If anything, I'll probably be the one getting smushed the most..."

Natsumi rolled her eyes. "Ugh, I'm so stupid. Surely I could have gone about getting gravure shots of you Liella girls easier..."

Shiki's cold laughter above interrupted the pair's squabble.

"You two sound so funny. Especially at that size. Enjoy your time in there, I'll talk to you both later." With that final sendoff, the hand Kinako and Natsumi were settled on tilted to the side, like a claw machine depositing its prizes. The two tiny idols were dropped into the deep abyss of school idol Shiki Wakana's cavernous cleavage.

Kinako landed face first on a mass of flesh and bounced off, barely able to keep the tinier Natsumi in her grasp. Natsumi held onto her friend's finger for dear life as the two tumbled down deeper. The brunette bounced between the gigantic orbs of fat a few more times and, after eventually losing momentum, settled between the two breasts closer to the top.

"That tickles a bit. Try to play nice in there, you'll have to tell me all about it for my notes later," were the last words spoken by their large friend as Shiki let began buttoning up her shirt again, sealing the two inside for the day.
