With so much time to herself in the ruins, Toriel had devoted herself into trying various new hobbies. There wasn’t much else to do, after all. She had long since eaten the other monsters in the ruins, something she’s come to regret over the years. Toriel had been used to having endless citizens to gorge herself on, but the population of the ruins was next to nothing even before her self-exile. Snails simply couldn’t compare to the meaty, mouth-watering taste of meat…
 
She tried her hands at all sorts of ways to pass the time. Baking and knitting had become second nature, and she enjoyed reading the occasional book. (Only occasional due to the lack of literature in the ruins, of course.). One she had taken to fairly recently, though, was nudism. As far as she knew, she was the only one who resided in the ruins anymore. Every morning, she took off her robe and went for a walk around the ruins. Her proud potbelly wobbled with every step, her rear making wet claps that flung sweat wherever she went. Her fur-coated breasts swung side to side, the nipples rock hard from the chilly draft and sensitive to the touch. For being trapped inside a maze of stone and traps, she had never felt so free.
 
After her walk, she always went to the flowerbed for a nice midmorning nap. Not only did the flowers provide for an impossibly-soft rest, but the flowers basked in glorious, glorious sunlight. No monster outside the ruins had ever seen sunlight, nor knew how wonderful it was to bask in it. The warmth of the above world always ensured that Toriel would have an amazing nap, clothes or otherwise.
 
One morning, she laid along the flower bed, fast asleep. Her oversized belly lifted her off the floor, gurgling loudly with the desire to eat anything other than snails. Toriel’s ass was hiked high in the air, taking the brunt of the sunlight raining down on her. Her odd position and loud snoring resulted in an unladylike rest, but a comfy one.
 
That was, until she felt her asshole stretch open to an impossibly wide degree. Something huge was crammed into her unsanitary insides, causing Toriel to wake up with a jolt. “Oh my-!” She gasped, looking up and behind at her rear. Something had fallen from above and was now halfway lodged inside her asshole. Toriel reached for her glasses and adjusted them, her cheeks going bright red as she saw what had so rudely dropped inside her insides: A human.
 
“My goodness!” Toriel yelped, rolling over onto her back and spreading her legs wide. The human’s top half was stuck inside her cheeks, their legs kicking like mad. She could hear an awful lot of screaming from inside her, unable to hold back a moan as their body struggled along her sensitive, starved innards. “You… You must really be more- NGH! Careful, young one!” She lectured, her asshole giving an instinctual tug as the human’s lower half was yanked inside. With her guts fully occupied, Toriel felt her insides shift and groan. “Oh dear-”
 
FBRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRT!
 
A plume of vile, lung-rotting gas spread around the area, causing Toriel to gag and the flowers below her to wilt. Toriel’s face was bright red as she waved the stink away from her face. “M-My word! I haven’t… ah, done that in a while… It’s wonderful!~” She groaned, stretching out around the dying flowers and starting to finger her cunt and shitter with both hands.
 
The human inside didn’t enjoy the sensation nearly as much. The smell made them scream and cry, no doubt begging for mercy as Toriel’s guts gurgled and squeezed from her pleasuring. Her ass blasted even more fumes as her body became active, sweat dripping from every inch of her body as her body thrashed and squirmed, the human inside being jostled around without mercy.
 
“Oh yes! OH YES!”
 
FBRRRLRRRT! FORRRRRRRRRRRBLLLL! FRRRRRRRT!
 
The moment Toriel climaxed, her insides CLENCHED. The bulge in her lower half suddenly shrank down to nothing as the human was mulched away. Toriel let out a VERY unladylike BWWWWOOOOOOORP!, having to cover her maw in sheer embarrassment. She felt a twinge in her colon, the weight of her lower half quickly increasing as her asscheeks grew a few extra inches. Toriel slowly got to her feet and stretched, her stomach gurgling once more.
 
“Goodness… I haven’t had a human since-”
 
GORRRRRRRRGLLLLL…
 
Toriel’s legs crossed. Food always went right through her, and what remained of the human was ready to get out. Toriel knew she couldn’t make it back to her house in time, and so she took a squad over the bed of dead flowers.
 
“Hnghh… I haven’t done this in… in- UWHHHH!~”
 
Her asshole stretched open wide as a log of shit crowned from her cheeks. The turtlehead was several feet thick, her overactive guts always making a mountain out of a molehill (Or food, in this case.). Toriel grunted and groaned, panting heavily as she worked on pushing as hard as she could. The steaming, light-brown log pinched off on the ground, another one quickly piling on top of it. The flowers acquired some much-needed fertilizer, not a single speck of yellow able to be seen under all the waste. Toriel began to finger herself again, spraying a load onto the stone floor before her.
 
After several minutes, she finished her little dump. She took a step back and admired her handiwork- A pile that reached nearly five feet tall and smelled simply horrendous. She took a big whiff of the pile, proud of a meal well digested as she patted her gut.
 
“I missed that so dearly… Hm. Maybe it’s about time I visited the capital~”
