    Summary

    After waking up in a strange place with little to no memory of who he is, Sans finds himself accepted among a group of strangers that call themselves "the Family," hidden deep within Snowdin forest. Everything seems fine, if not a little restricting, but he's okay with that, and is happy to be apart of a group, despite his worries that things aren't the way they're supposed to be. After all, he has a family, and there's nothing wrong with that, is there?

    But of course, nothing good ever lasts, and Sans finds himself uncovering dark secrets of the Family that put it in a whole new light. The only decision he has to make is if he'll stay knowing what he does or try to escape--and either way, it may get him killed anyways.

    Summary

    Frisk made a promise to her friend. Though she didn't know what it meant at the time, she promised to never reset the timeline again. The concept of resets was strange to her, she believed it an easy enough promise. No matter what, she was determined to keep it.

    Sans made a promise to her in return. He would do everything in his power to keep his little human safe. No matter what happened to them after the barrier broke and she became public enemy #1, he managed to keep his promise too.

    Eight years later and both promises have been kept.

    But promises are made to be broken, aren't they?

    Summary

    Frisk sang for a living. She sang in clubs that were populated by mobsters, murderers and the most violent criminals her city had to offer. She honestly thought things couldn't get any worse until corruption in the form of a grinning skeleton came strolling into her life. His name: Sans.

    She tried to run, but no matter where she went he was always waiting for her.

    Summary

    Monsters may be free, but there is a high price to pay for the one that freed them. Deciding Frisk is better off being a mystery, the monsters leave it alone for 14 years. Until Frisk is discovered. Undyne and Sans try to reach her in time, but she is left with a fatal wound. With even boss monsters unable to heal her, Sans heals her the only way left.

    However, that was part of Gaster's plan . . . but Flowey was not. The result is wedding bells ringing twice for Frisk. Once to Asriel . . . and once to Sans?

    *Frisk and Sans eventually.

    Summary

    "Whisper a dangerous secret to someone you care about. Now they have the power to destroy you, but they won't. This is what love is." - Welcome to Night Vale

    A haphephobic glitch and a nymphomaniac, together as a couple. Nothing can go wrong there, right? Not as long as respect is shown, at least. And Lust is quite a respectful monster. Error, not so much, but hey, sometimes sacrifices have to be made for the one you love.

    In other words; a collection of Errorlust/Errotic-fics. There might show up some other Lust-ships now and then, though, but it's mainly Errotic.

    Warnings in every chapter they're needed!

    Summary

    As a rite of passage held by arcane law, all mages upon reaching adulthood must summon and bind a Familiar to themselves for servitude, protection and battle.

    ...Of course Frisk's has to be a lazy skeleton that doesn't do anything other than eat, sleep and crack horrible puns. And has the lowest stats of any summon in recorded history. She's the laughing stock of the Order.
    She pretends not to notice that underneath the visage of the docile Familiar lurks something far more cunning, sinister. That looks at her with murderous intent, fury and...possession.

    For no-one truely remembers exactly what the Familiar Bond is...even as war looms on the horizon.
