Mio was extremely nervous about an upcoming concert and her friends were trying to calm her down. Unfortunately, they weren't having much luck so Mio just ran outside and tried to stop hyperventilating. She soon calmed herself down and took a few deep breaths. Once she stopped freaking out, she leaned against the wall of the school and slid until she was sitting down on the ground.
"I thought I was better than this." she said to herself.
"What's the matter with you today?" said a voice familiar to hers.
"Oh hi, Ritsu." she said looking up at her friend.
The brown-haired girl frowned.
"You're not normally like this." responded Ritsu.
The dark-haired girl sitting in front of her just looked down at the ground.
"I'm sorry." was all she could say.
"Listen." said Ritsu, "I know things have been difficult lately but… we'll get through them. We always have."
"You're right..." responded Mio.
"I've got something to cheer you up too." said Ritus, beginning to undo her shirt before it quickly fell onto the floor.
"W-what are you doing!?" asked Mio who looked straight at Ritsu's breasts which were contained with a yellow bra.
"Something you'll like." she said as she took her skirt off, showing her yellow panties to her best friend.
Before Mio knew it, Ritsu was starting to undo HER shirt and she started wiggling around, trying to break free from her friend's grasp. The upper part of Mio's uniform had been taken off and now her gray bra was exposed to the air outside. Her huge amount of cleavage felt a nice breeze when she suddenly felt too tired to fight.
"Open up." Ritsu said.
Mio was uncertain of how to react to what was going on but she went with it anyways and her mouth opened. Then Ritsu gently pushed her head inside and pushed herself toward the back of her friend's throat. Still not doing anything, Mio just let Ritsu push on even further. Ritsu's head started slowly going down her throat. As Ritsu's chest entered her mouth, Mio then grabbed her sides, and began attempting to pull her out, but Ritsu managed to push herself in further. As Ritsu's chest got past her tongue, Mio realized she was enjoying how her best friend tasted.
Mio swallowed Ritsu's stomach, enjoying the taste of her bare skin on her tongue. Ritsu's body was now soaked in saliva. Ritsu let out a moan when she realized Mio was really enjoying her. Ritsu's hips entered her mouth next. The girl's upper body had reached Mio's stomach and it was growing to make room. Mio could see it expand from the outside and she enjoyed the feeling as Ritsu filled her up. Ritsu's legs were hanging out of Mio's mouth and she slurped them up and then her whole body splashed in Mio's stomach acid.
"Feel better now?" asked Ritsu.
"Y-yeah." she said, "A little."
"Good." responded Ritsu.
"H-how do I get you out?" asked Mio.
"You have to digest me first." answered Ritsu.
"W-what!? But you're my best friend! I can't just-" started Mio.
"Mio, I'm in your belly." her friend responded, "Just think of me as food."
"B-but."
"I'm food."
"Why would you want this?"
"Can you just start digesting me already?"
"F-fine."
It didn't take much longer for Mio's stomach acid to start bubbling. It slowly started to rise up past Ritsu's panties and went all the way up to her bra. The walls of Mio's stomach started slowly moving her around and then splash some more acid onto her body. The digestive fluids dripped off of the walls, most of it landing on Ritsu's bare skin. Some of it went in between Ritsu's boobs. Ritsu then started rubbing Mio's belly from the inside.
"W-what are you doing?" asked Mio.
"Making you comfortable." said Ritsu.
"Well, I guess it does feel good." she said, putting her hands on her belly.
"Yeah." responded Ritsu, "It should also help with digestion."
"Thanks for doing this, I guess." said Mio.
"No problem." responded Ritsu.
Mio's stomach started moving even faster, way more digestive fluids dripping all over her and some of it leaking into her panties. Her underwear was being torn apart by the stomach acid and before she knew it, she was completely naked in her best friend's belly. She didn't care though. At this point, she was nothing more than a large piece of meat waiting to be digested. Flesh was melted off of her body so it could slowly be absorbed into Mio. Mio's chest slowly grew bigger as more of her best friend digested. Her belly slowly shrank over time and she paid attention to its size. She couldn't actually believe it.
Her best friend fed herself to her and was willing to be digested. Not only that, but she was enjoying it too! Then Mio thought about how delicious she was and wondered how many more opportunities to eat people she'd get. Ritsu didn't say any more to Mio and just focused on her digestion. Her form was no longer that of a human. It was just a mess of flesh, completely submerged by stomach acid and was eventually fully digested.
