    Summary

    That stinging sensation that engulfed Blue's entire body hurt. He was certain that paint wasn't supposed to burn. It still burned either way. But the pain was nulled by the overwhelming positive aura radiating off of Dream.

    Why was he allowing them to do this again?

    Summary

    The outcome of this stupid situation wasn't also something he could have ever predicted.

    Summary

    Once long ago, humans and monsters lived alongside one another. During this time it was an age of unparalleled magic and strength in the two sides.

    However, the great war happened, and with the absence of monsters mages slowly died out. After all, humans are not inherently magical. With no more magic to keep the blood lines going, magic is all but a fantasy in the humans of today. That is, until an eccentric billionaire decides the mages need a come back.
    Looks like you and a few others are just the right subjects to get the ball rolling.

     Oh right! There is some swearing in here.

    *WARNING* Some people are very sensitive to kidnapping/abduction themes. While I assure you, I probably won't go too dark, it is a bit... muddy in here. Tread lightly.

      Bookmark Notes:

      You’re broke, and decide to go get a “SOUL study” done for some quick cash.
      Sans gets dragged to a talent show by Paps to earn some quick cash.

      You’re both drugged and kidnapped for an attempt at breeding for mages along with 5 other girls and 5 other male monsters (Nicely, Doggo, Ice Wolf, Grillby, Burgerpants).

      You and Sans are paired together, and forced into a SOUL bond - only, your Integrity SOUL isn’t too happy about that. After struggling to accept the bond, you two become close. Everyone else is paired off and forced into bonds too, each boss monster paired with a SOUL trait of their own. Perseverance and Kindness get pregnant.

      Meanwhile, you’re all still trying to find a way to break out.
      When Mettaton stumbles upon this operation, he and Flowey make a plan to break you guys out… and everyone does get out… except for you and Sans - after many resets that only you can remember, you realized there was no way to get the 10 others out safely without sacrificing yourself to be left behind. So you stay, get recaptured, and get sent to a new facility.

      Alphys, Undyne, Toriel, Papyrus, Mettaton, Frisk, and Flowey continue to look for you and Sans.

    Summary

    Using Frisks Soul, Asgore manages to bring down the Barrier, in the process absorbing the souls and becoming a being of unfathomable power. Using a monster army and his newfound strength, he takes over a town at the base of the mountain.

    Monsters become the reigning power, and a human slave trade blossoms in "Overground" (so named by Asgore). Monsters own humans as butlers, pets, and entertainment.

    Sans never thought he would personally own a human servant, but after a chance encounter, he has to face his worst fear - living with the same creature as the one that haunts his worst nightmares.

    Summary

    The infamous Sunrise Sureshot.
    A man of many names. Just ‘Sureshotʼ to most, ‘Sunnyʼ to a select few, and Papyrus- his real name- to even fewer.

    An outlaw with an aim as sure as the sunʼll rise in the morn, he and his brother have been terrorising the New Ebott railways for the last three years; a stain on your formerly pristine reputation. Youʼre determined to lock them both behind bars of course, but yʼsee…

    Letting out a muffled curse, he goes still as you bring your boot up to rest on his back, heel pressing dangerously into his spine. He shivers as you lean more of your weight onto him, pushing his chest further into the dirt.

    You and “Sunny” have history.

    Cowboy AU which has been haunting me since 2022, it's smut that grew heavily implied plot. Reader is a sheriff and Papyrus ("Sunny") is an outlaw
