    At your look he smirked and purposefully moved a loop of coil over your legs. The weight was probably going to put them to sleep after a while. And from the amount of blankets and pillows you were suspecting you weren't going to be able to even sleep on the bed. Which was now normal any time it was a movie night.

    Summary

    While doing some illegal drugs with a friend, you accidentally trap yourself in one of Papyrus's puzzles. He gets you down and brings you to his home, deeming it unsafe for you to go alone. You meet his brother and eat some welcoming spaghetti. It's one hell of a night and you're pretty sure something fishy is going on, so you keep visiting the set of brothers until you're able to find out. This ends up with you bonding with two socially awkward and touch-starved skeletons and beating up another skeleton.

    Summary

    When you were younger, you had everything.
    Anyone in their right mind would have stayed.
    You chose to leave. To this day, you had no excuse for your actions.
    You just left it all behind.
    You moved to Ebott city, home of the monsters, and created yourself a new life.
    Your only income now comes from The Grounds, where you fight to unconsciousness for the big bucks.
    Most fought here when they hit rock bottom, You fought here because you wanted to.
    The Monsters have been above ground for some time, You never kept track, never kept track of anything.
    Mostly because you didn't care… about anything.
    When three sets of skeleton monsters come into your life, showing you warmth and kindness you’ve been refusing all this time, you start to look at the world in a new light.
    Why don't you care?
    And why do they care so much?

    Summary

    Moving from a backwater town to a city bustling with human and monsterfolk alike, some things begin to change both for the better and the worse. What was left behind comes back to bite at you in the most unexpected times, current progress being put in danger as a result. It's hard to move on, though it's equally difficult trying to stay loyal to what you believe is right.

    With an adoptive seven-year-old son and the remnants of a recent divorce in your hands, your goal is to move on and adjust to life with monsters, these becoming an important part of your life -- one of them in particular reigniting the spark you thought gone with your ex spouse.

    Summary

    Well, this wasn't your worst idea, but certainly wasn't your most thought out one. It was just a sudden impulse fueled by your curiosity that made you sign up. However, this spark of recklessness seems to be the reason why your life is turned upside down and full of more monsters than you know what to do.

    Summary

    As a child, cold and hungry in the Snowdin Forest, Edge is visited by an angel who gives him a treat and makes him laugh. Red doesn't believe him, but he knows it was real. He lives his life knowing that the angel helped him so that he could go on and help others. The memory of that night is with him always, guiding him and helping him persevere through the hardest times.

    Years later, when his brother gets the machine in the basement working again, he meets the Underswap brothers. One of them bears a striking resemblance to Edge's angel. Could it be?

    What happened to Rus to make him so bitter when he'd been so sweet all those years ago? Can Edge help him rediscover himself?

    Summary

    (Y/n), a high ranking Platoon Commander in the Military, was on a mission with her squad when her plane was shot down by an enemy ship, leaving her stranded on an unknown island, with none of her comrades in sight.

    It would have been all fine an' dandy... if she wasn't surrounded by three Alpha Skeletons and one Omega Skeleton. All of which want to fuck or be fucked by her.

    So now here she is, having to assess her dominance as an “Alpha” to get by with her limbs still attached and her clothes still in one piece. Even if one of them looks like he came straight from Satan's asshole.
