In the Lindworm Central Hospital Doctor Cthulhy Squele was teaching a class all about the stomach and the digestive process. The upcoming college students were of many races from humans to mermaids to even harpies wanting to learn all about medicine and all kinds of things from the famous doctor. Cthulhy was a tall busty woman of the scylla race. Eight red thick tentacles under her, long red hair in a ponytail and glasses to give the doctor look off. She wore a white doctor coat and a white shirt which her boobs really pushed out.
 "Alright class to really get a good description of inside the stomach how about I get a volunteer to get inside mine and describe it I'll let you out afterwards don't worry" said Cthulhy
 A few hands raised up and Cthulhy looked at the ones and found the human female to be the best and easiest one to eat. The blonde's name was Jessica and she wanted to be a doctor so getting a lesson like this was good for her. The skinny blonde wearing a green sweater and grey pants stood up and walked over to Cthulhy. Cthulhy gave the girl an innocent smile as she wrapped her in her tentacles and lifted her up. It felt slimy and weird being wrapped in Cthulhy's tentacles and Cthulhy opened her mouth up and the class watched as Jessica's head was stuffed  in the doctor's mouth. The warm tongue brushed over Jessica's face and Cthulhy held onto her hips with her regular arms as she used only her tentacles to push the human inside her mouth. Jessica felt her shoulders go inside of Cthulhy and blushed a little as she was so effortlessly eaten whole. The class was definitely in awe not knowing Cthuhly could do such an action and in itself was pretty intrigued. Jessica's small breasts rubbed onto Cthulhy's mouth making the scylla woman giggle and play around with them. Jessica moaned and blushed as the wet sounds of her body being pushed deeper inside erupted in her ears while her boobs were teased. 
*gulp..glrk..gulp*
Jessica's toned midsection was slurped up by the ravenous Cthulhy who was able to get her tongue down the bottom of Jessica's sweater and licked the belly button and stomach.
 "Hey um Cthulhy stop that..it feels funny" moaned Jessica
 The class watched Cthulhy gulp again and the stomach was starting to get bigger. They saw the imprint of their classmates' faces start to bulge and pushed the stomach out. They heard her muffled yelps as Cthulhy continued to tease her student. Cthulhy gulped down Jessica's waist and started on the small ass and was a little disappointed in the lack of meat but the thighs looked like they would do just fine. Cthulhy swallowed the butt and slurped in the thighs making her belly pop out of the white shirt and now everyone could see the bare stomach of their teacher. Cthulhy giggled and licked the thighs getting little more reaction from Jessica before deciding to go ahead and finish her off. Cthulhy slurped in the thighs and with her tentacle removed the shoes and pushed the sock covered feet in her mouth and gulped. Cthulhy let out a satisfied sigh as she finished swallowing her student and the class watched as Cthulhy's gut ballooned out and laid right on top of the desk.
 "Now that you have entered my stomach please describe what it's like inside" said Cthulhy
 Jessica wiggled around and started to study where she was at before speaking.
 "Well it's very tight like being stuck in a wet tight sack, the walls are all slimy and the stomach acids were covering my body while also pooling up on the ground...um a low groaning noise as the stomach is starting digestion" said Jessica
 "Correct thank you now let's go with class shall we" said Cthulhy 
 Cthulhy went back to explaining digestion and stuff as Jessica and the rest of class was stunned. The class just went ahead and went along with it and ignored the fact that Cthulhy is leaving their classmate inside her stomach. Jessica squirmed a little and pushed the walls out.
 "Um Dr Cthulhy I think you're starting to digest me..can you please let me out now" said Jessica with a little nervous laugh at the end
 Jessica was ignored and she realized she'd been abandoned and was going to be digested. Jessica pushed her body and legs trying to get Cthulhy to forcefully puke her up. But little did she know the scylla race had very powerful stomachs and it didn't matter how much she struggled or fought back Cthulhy would have to willingly throw her up.
 "Obviously when food is digested it is turned into waste and I'll have a little demonstration for that in about an hour for now I'll describe the process of food being digested...first the acid comes and drenches the food" said Cthulhy 
 Jesscia felt acid all over her body which lightly stung her body getting a feel for the large piece of meat. Jessica watched as her grey pants and green sweater were being ripped to shreds by the harsh stomach acids.
 "For sometime it will slowly break the food down turning into a more soupy substance that can easily flow through the person's intestines" said Cthulhy 
 Jessica whimpered, feeling her body getting softer and softer and it just seemed to go along with Cthulhy's lesson. Her clothes were torn away from her body making the skinny girl very exposed to the stomach acids. Jessica was being turned into a soupy substance for the lesson just like Cthulhy had planned for.
*bwarrrprp*
Cthulhy belched and blushed while covering her mouth.
 "I'm sorry about that the volunteer is getting a little rowdy in there" said Cthulhy 
 Cthulhy went on and some students had their eyes on the belly entranced by the belly as it moved and would slowly lose its shape. Jessica cried and begged for her mom as her body was falling apart.
 "I made it all this way...only to be eaten by a doctor" cried Jessica
 "Don't worry you'll be a great sacrifice in the name of medicine" said Cthulhy
 Jesscia just buried her face into her knees and waited for her impending doom. Cthulhy went on and the class just listened and would occasionally check on the rounding out stomach.
*gurgle..glorp..churn*
The classroom filled with Cthulhy talking and the sounds of a churning belly. Poor Jessica was losing her mind as she had to watch her body fall apart before her eyes and mix in with the slurry of mixed acid. The pool had raised to her small chest and her soft body could barely take anymore. She could barely move and Jessica knew her legs and butt were about to be smashed together. 
*snap..gurgle..slorsh*
Cthulhy's belly did away with Jessica crushing the soft girl down and soon enough no bulges remained and only a soft gurgling round belly was left. The mush that used to be a student was pushed into Cthulhy's guts and the stomach shrank down as the girl became fat on Cthulhy's bust and tentacles. 
*flwarrrppp*
Cthulhy farted and turned around and finally noticed her belly was gone.
 "It seems our volunteer wants to be let out...this will be the final lesson of the day so watch closely" said Cthulhy 
 Cthulhy climbed on her desk and turned around to show her giant ass off before squatting over the desk with her asshole pointing to the ground below. 
*flwarrrrppp*
Another nasty smelly fart ripped from her anus and the class gagged a bit. Cthulhy then loosens her asshole and the former volunteer starts to rush out. Big turds started to fall out from Cthulhy plopping on the ground making a nasty mess. The shit started to pile on the tiled ground and some would splash and hit the front of Cthulhy's desk. Some students were starting to get horny from it while the others were either disgusted or fascinated by the final lesson. Jessica was no more as only her bones and clumps of her blonde hair survived digestion. The young college girl was reduced to scylla scat and was just an example for some other students.
 "As you can all see..urgh..the volunteer has been turned into poop which was caused by digestion...jeez there's a lot" said Cthulhy 
 Cthulhy grunted and pushed giant turds out filled with bones. Jessica's remains piled up pretty high to the point the pile was as tall as the desk. But Cthulhy crapped the skull out and it was all done. She used a few papers to wipe and then got back behind the desk.
 "Well that was today's lesson..you can take samples of the final product to study or do whatever with it" said Cthulhy 
 Cthulhy left and everyone had no idea what to say or do.
