    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.

    Summary

    You’re just an average, happy human, going about life, trying to forge your way in the world. Fortunately, you’ve landed a nice job that pays well, you’re steadily and reliably working your way out of the debt you gained from moving to the city, and you found a great apartment (with a chill roommate, Sans, a polite skeleton monster with puns up his sleeve and an indecipherable gaze) for surprisingly little rent.

    Everything’s fine.

    And then, without warning, two more skeletons seem to show up out of nowhere at your and Sans’s shared apartment. The first to appear is Red, a hot-blooded, sharp-grinned alcoholic who isn’t shy to share his less than savoury intentions with you, with crude gestures and pick-up lines galore.

    ... And the second is a tall, broad, but quiet skeleton who immediately goes by the pseudonym Skull, sporting a huge crack in his head and a single, engorged red iris, that never seems to stop staring at you.

    You’re not sure why both of them won’t leave you alone, or why Sans seems so desperate to stop them from interacting with you... But hey, what harm could come from it?

    Summary

    When Sans and Asriel decide to shift several people into an alternate world based on Asriel's unpopular tabletop RPG, everything goes wrong when the two masterminds retain no memories of their past life. However, this glitch in the machine causes another person to remember everything. You remember your life as Papyrus's spouse, you remember her transition, her arguments and fights with Sans. You remember being kidnapped by Asriel and forced to watch as Sans turned your entire world inside-out.

    When Megumi awakens as the Crown Princess of the Fire Nation, she remembers nothing of her past life save an unpleasant dream which quickly fades. She has twenty-four days to choose a suitor. Will she choose Queen Tanhua, of the Earth Kingdom, who cares only for her own people? Perhaps the fabulous Prince Pardoq of the Northern Water Tribe? Or Avatar Mara, keeper of peace among the nations? But who's this mysterious criminal, locked away in the darkest dungeon?? Something in Megumi's soul draws her to you, despite knowing she should stay away, and despite her creepily possessive half-brother's orders to leave you alone.

    Summary

    A work conceived from the fact that I have too many ideas I wanna write, and the fact that I'd go insane if I 1. Wrote it all and 2. Didn't do *something* with them

    The concerningly vast majority of those ideas include kidnapping, being stalked one way or another, with Sans right there behind your back wherever you go. I might even make them full fledged if I get invested enough (though that's not very likely as of now)

    So if that's your thing.... Go for it! Hope you have a thrilling fun time of having the feeling of being watched, hearing footsteps in the dark, and eyes watching you when you turn off the lights.

    Summary

    'Don't stare, don't stare'. You keep telling yourself that, but it's not helping. You really wish you could take your own advice, but who could blame you. You just couldn't take your eyes off of him. You heard about the rumors and whispers on the street. You brushed them off at first, but now you really wish you had listened. You didn't believe any of it...until now. It seemed everything they said was true, there really were monsters living among us. It's hard not to believe in something when it's right in front of you. And that something just happened to be a 9 ft tall skeleton monster that smelled of mustard.

    Summary

    Most of humanity hates monster kind. Although given equal rights, police don't protect them, and no one seems to try and support them. Humans stay on one side and Monsters stay on the other.

    Hazel Smith was no different from other humans. Fearful of Monsters, she tries to avoid anything that has to do with them. No human blamed her. They were large, terrifying, bloodthirsty creatures from what she's heard.

    She can't exactly escape them when an energetic skeleton monster ends up being her soulmate.
