Things weren't going great for the shrunken pair between Shiki's tits. While it was going fine at first, the temperature had been on a steady rise. Or rather, it was already incredibly hot the moment they entered Shiki's cleavage, but now their tolerance was wearing off. Shiki's boob sweat had completely soaked through Kinako's school uniform. Natsumi had it even worse, as Kinako had placed the tinier girl in her own cleavage. Natsumi did not find this very funny, despite Kinako trying to keep a lighthearted attitude about the situation.
"Goddamn it's hot in here... I'm dying! I need a drink!" Natsumi complained, something she'd been doing for the entire hour they'd been trapped so far.
"Well, there's plenty to drink but... I wouldn't recommend it..." Kinako joked, still trying to force a smile.
Shiki's massive titties continued to press against Kinako's body on all sides. She was trapped firmly between her classmate's boobs without any reprieve. Her arms were sore and her legs had fallen asleep from hanging midair for so long. Every step Shiki took sent tremors throughout her body, jiggling her breasts like a plate of jello. Shiki's heartbeat was a constant, and her breathing, while barely noticeable at normal size, made the heaving breasts holding her friends captive move up and down rhythmically.
"I-I really do hope she lets us out soon though. It's not very fun sitting between a girl's breasts all day..."
After far too long, class was over. Shiki went to grab her bag hanging from the hook on her desk. Accidentally losing her grip, Shiki's schoolbag fell to the floor. No big deal usually, but there was something extremely important and highly delicate inside her bag today.
"The shrink ray!!"
Scrambling to open up her bag, Shiki's fears were realized. The shrink ray had gone off when it hit the ground. It's targets were still set to Kinako and Natsumi. But the size...
"H-holy..."
The size was set to 1/1000 of an inch. Imperceptible to the human eye. Kinako and Natsumi would be so small that the pores on Shiki's skin would become an endless expanse of land to them. Not to mention they were currently in her cleavage. Even the slightest movement and they'd be easily crushed by her boobs.
Female students walked by Shiki, still crouched down on the floor of the classroom. Terrified, Shiki began removing the ribbon of her uniform and unbuttoning her blouse. Uncaring of what others saw, she opened up her blouse and exposed her cleavage to the outside world. Parting her breasts with her index finger and thumb, Kinako and Natsumi were nowhere to be found.
"Shit shit shit..."
Shiki checked her shrink ray. Kinako and Natsumi's vital information was unavailable. Either they had shrunk too small to be properly tracked, or Shiki had crushed them with her tits the moment they shrank to 1/1000 of an inch.
Immediately setting their sizes to 1/1, Shiki hoped and prayed Kinako and Natsumi survived. Killing her friends with her huge boobs was not on her to-do list today.
Nothing. The shrink ray's screen showed that Kinako and Natsumi could no longer be tracked. It was over.
Shiki buttoned up her shirt while students whispered behind her back, surely starting up some weird rumors about the girl who suddenly started stripping out of nowhere. Surely there was still something that could be done, hope wasn't lost. If Shiki could increase the range of effect on the shrink ray, she could hopefully track down Kinako and Natsumi no matter how small they were... If they were still alive, that is.
Shiki shook those dark thoughts away. She just had to hope they were safe and sound living on her tits. They'd be like entire planets to them at their size.
Ignoring her gossiping peers, the blue-haired school idol slowly walked to the school's lab, trying to avoid making her large breasts bounce as she walked. Something easier said than done. It was time to get to work, she could fix things, she just needed time. Hopefully Mei or any of her senpai in Liella wouldn't ask any questions.
She could definitely get Kinako and Natsumi back... Maybe.
