The literature club had been making plans to go on a trip to the beach for a while, but all of the beaches were closed. They didn't have any luck with pools either, so they met up at the clubroom to discuss. The conversation went on for a while but it ended up taking a bizarre turn.
"I've got it!" said Monika, "What if we swim inside someone's belly?"
"What?" responded Natsuki , "Were you dropped on your head as kid or something?"
"Well…" said Monika.
"I wanna do it!" exclaimed Sayori .
"You'll get digested." said Natsuki , folding her arms.
"Just… think about it." suggested Monika.
"If we do it," you said, "who eats the rest of us?"
"That's a good question." said Monika, "We'll figure it out when we get there."
While you don't get everything figured out then you still make plans to meet up the next day. When you walk into the clubroom, you see something you weren't expecting to see. All four of the girls are wearing a swimsuit. Monika is wearing a brown bikini, Yuri's is purple, Sayori's is orange, and Natsuki's is yellow. Looking at the girls, you can see Monika and Yuri have the most cleavage.
"You gonna go get changed, _?" asked Monika.
"Oh, right!" you said, before leaving the room.
You get back wearing blue pair of swim trunks.
"So how are we going to do this?" you asked.
"I'm going to shrink you guys down and then swallow you up." answered Monika.
"What about you?" asked Sayori , "Are you going to go swimming in someone's belly too?"
"I don't know." she answered.
"She knows she can get away with digesting us whether she gets eaten or not." said Natsuki .
"Hey, you guys all consented!" responded Monika.
"Yeah, whatever." responded Natsuki .
"So, who's first?" asked Yuri.
"I-I'll go." you offered as you approached Monika, who stood behind the desk at the front of the clubroom.
Once you get there you find four cups sitting there and Monika tells you to drink one of them. You reluctantly drink one of them, and you find yourself slowly getting smaller. Before you're know it, you're much shorter and standing on Monika's desk. You look up at her, and she's huge. She picks you up and you gulp nervously as she brings you to her slowly opening maw. You may be small, but she only shrank you to a certain point, so she could only fit half of your body in her mouth at time. Your upper body goes in first and then your legs and you go down her throat like it ' s a water slide and splash in her stomach acid.
The other girls approach the desk, and all take a drink from a cup at the same time. They all shrink down to the same size as you. Monika grabs Sayori next and slowly brings the girl to her face. She slowly swallows her down and sends her in after you. The next person she swallows is Yuri, who goes in at approximately the same speed. After that, Monika reaches for Natsuki .
"I guess I have no choice." said Natsuki , "Today I get digested."
Monika slides her into her mouth. Natsuki's face slides down her throat and then as her body descends, Monika traces her outline with her fingers until she makes it to the stomach and splashes in the acids with everyone else. Everyone stands up, and for Natsuki the acid reaches slightly above her chin and for everyone else it's about above their stomach and close to their chests. Natsuki sighed, realizing she would digest the easiest. However, this didn't stop the rest of you from playing around in there by splashing the digestive fluids on each other and softening each other's skin. On the outside, Monika contentedly patted her belly.
"Have fun at the 'pool', guys." she said.
Over time, the club members inside Monika's stomach start running low energy and start moving a lot slower, due to how much softer their bodies have
become. Natsuki can no longer do anything because a good chunk of her lower body got digested, causing her to lose her balance, allowing the rest of her body to digest more easily. Y ou smile, happy that you got to spend this special time together with your friends and eventually you, Sayori , and Yuri pass out.
