    Summary

    Created by a laboratory along with other Monsters, (Y/n) or as she used to be known SKE-7, has been on the run most of her life from the shady group simply called 'The Company' that sought to use Artificial Monsters as tools or weapons. She lived in hiding with the scientist who made her and his son for years when suddenly Monsters came to the surface from under Mount Ebott, not long after Monster experimentation was declared illegal finally giving (Y/n) the chance to live out in the open and achieve her dream of being a Chef. Sadly Skeleton Monsters are quite rare, but just as she thought she'd be the last of her kind she runs into some unexpected, or we should say a skele-ton of surprises! Our Skelly is free at last to enjoy her life...but are there trials ahead?

    Summary

    There is no romance in a nighttime security job at the local cemetery, but Lauren Silverman needed a job. The cemetery had an opening for a new night guard. Nothing unusual about wandering a cemetery every night making sure the local kids weren't being mischievous and keeping graves from being robbed. It's a boring job but pays well. She can catch up on her reading list, even. Maybe make friends with the cute cop who always works night shift and invite him for a midnight stroll through the headstones. The fun stops when she comes across a new prank the local kids have pulled on her; a skeleton sitting under the full moon's glow, admiring the stars. "This is a new low," Lauren mutters, intending to lecture the brats for stealing the expensive science room prop. However, when she goes to dissemble the jump scare, she gets startled when the bag of bones turns and grabs her wrist! At first she screams from terror, but later? Well...

    Summary

    There would be no tongue to meet yours, no scalp for your fingers to scrape. No half-hard cock to coax into fullness, to take into the warmth of your wanting mouth until it was rock-hard and aching.

    But could you slot yourself between his hips? Feel the curve of his pelvic girdle supporting you? Could you grind against his coccyx, seeking friction? Could you take his phalanges and guide them into the soft, wet heat of your body?

    Would he feel it?

    No skin, no nerves, no raging synapses. But perhaps, somewhere deeper—in his marrow, where he is still soft - would he feel something?

    Would you?

Buscando formas para mantenerse cuerdo en el bucle infinito que es su vida a causa del niño humano y la flor decide hacer una parada recreativa en el metro, más específicamente al único lugar donde la determinación del niño no puede afectar, el laboratorio escondido en lo más profundo de las entrañas de True Lab.

    Summary

    Slight horrordust at the start.

    Dust hates himself and everything around him. Frequently indulging in self harm and other unhealthy coping mechanisms. He’s quiet and short tempered, especially around killer.

    Killer is childish goofy and annoying, completely and utterly obsessed with dust, in love would die for him. dust hates it but killer is also the only person who can help him with his mental state.

    Dust on the sidelines is casually hooking up with horror, which is heartbreaking to killer, but he still continue to be there for dust and help, no matter how awful dust treats him.

    Honestly super embarrassed and scared to post this, ain’t written an undertale story in years so please no hate 😭😭 probably won’t be updating any other stories for a while.

    Summary

    The earliest memory Sans had was raising Papyrus. He made sure he was strong for both of them and Sans would always be there when his baby bones needed him. Throughout the years, the brothers had a fairly normal and happy life together...So why is it now that Sans is suddenly having these reoccurring nightmares? Why is he having these random memories of scientists and experiments? And how can he possibly explain these horrid events to Papyrus? It was all too much for Sans alone. Papyrus, who's now a young adult, desperately wants to help his older brother. Now Sans is finding himself being taken care of by his little brother, realizing maybe he's not quite the kid he used to be. Having the roles changed, he's now the one being comforted, fed, watched, and feeling more small and helpless than ever. Now all Sans can think of is, who's really the baby bones now?

    Summary

    There was no hope.

    There was no way out of this place. Sans knew that from the depths of his soul- he couldn't escape on his own. But without any way to contact anyone and no knowledge of where he's trapped, all he could do was try to survive... or maybe just hope for death.

    No more resets, after all.
