    Summary

    Sans thought he'd lost one of the people he cared about most when Frisk gave her own life to stop Chara. As he sat there, rocking the child's still form, he made a promise... one that he'd do anything to keep. Then, a tiny skeleton baby with wispy brown hair gives him the chance to make things right and Sans comes to learn the joys and pains of being a father to his little girl.

    Pregnancy smut

    Because I need it.

    __

     

    Jeeze, it was just your luck to run out of oil in the middle of winter, wasn't it?

    You had been so enraptured in your pregnancy you hadn't even realized you started running low, and unfortunately for you because of the storm no one could make it out for atleast a couple days.

    Great, just wonderful.

    Luckily for you your mate was warm and cozy, and was more than happy to accommodate you.

    Summary

    Parallel to CounterTale, ContrastTale's universe has the same people with different stories...
    ConstrastTale: Kinship Version and ConstrastTale: Pursuit Version

    It is advised that you read "ContrastTale: Kinship" beforehand so that you can make connections.

    Sans has been leading a double life for years now; mainly he is known as being the king, and supposedly single, but not ready to mingle. Well, considering the other half of his life, where he comes to his secret second home into the waiting arms of the love of his life, a human mage name Rachel whom is more than meets the eye, and their daughter, Echo, who is much like her parents in demeanor.

    However, as Rachel anticipated, Sans is finally forced to meet the demands of his kingdom and search for a bride. However, as his Soul is already bonded to another, the truth will cause a lot of chaos. So, Sans and Rachel must race against the clock in order to find a solution that will appease the other world leaders. Surely getting some more help might not be so bad...

    Right?

    Summary

    They hadn’t even been on the surface two weeks when Frisk declared they wanted to take a road trip. They wouldn’t say why. They wouldn’t say where to exactly, either. Just that it was apparently quite far away from Mt. Ebott, and that there would be plenty of interesting sights along the way.

    “I know the way,” they said, and they sounded confident enough that their friends couldn’t help but believe them."
    ----------
    Written for doodleimprovement on tumblr as part of the 2016 Undertale Secret Santa. The prompt was: "family feels and Dunkle Sans." When Frisk proposes a road trip to show their new friends the sights on the surface, there's almost not enough room in Papyrus' new car to fit them all. Still, the surface proves to be a very interesting place. especially when you tour it with good friends by your side. And if Frisk has an ulterior motive for this roadtrip, well, it's not like the monsters don't owe the kid a few favors.

    When that ulterior motive involves a confrontation with the parents Frisk left behind to fall, Sans in particular is surprised to realize just how important this kid has come to be to them all.
