    Summary

    You were born in space, in one of the many Space Federation orbital colonies. You even spent most of your life in space, rarely stepping foot on actual planets. But you were determined to make the best of your life. You learned the ins and outs of nearly every ship still in circulation, honed your engineering skills to a fine edge. You were going to be the best you could! And maybe... Just maybe, find a place to really call home? Er, well... As long as you can keep within Federation rules.

    With all these skeletons though, this might be harder than you thought.

    Why is nothing working? Something hit the ship?
    You're gonna have to fix all this aren't you...? Here we go again.

    Summary

    Monsters have been living on the surface now for three years and it's time for your elementary school to integrate. Though you don't begrudge the little weirdos their education, things aren't easy.

    First of all, hate groups are targeting the school left and right.

    Secondly, the new skeleton janitor is keeping a judgmental eye on you constantly.

    Third - one of the new students seems to be a human called Frisk, and you're not quite sure how they got adopted by this monster family...

    Summary

    It may be a ‘kill or be killed’ world, but there was a secret that only the Skeleton brothers discovered that was much more important. Appearances and reputation were the most powerful things a Monster could have… and the two of them had that in spades. Now if only Red could get that pile of scrap metal to work and possibly get them somewhere safe... at least he hoped that's what it did... not getting blown up in the process would be good too... oops...

    Summary

    Sanses are playful, happy little pets who love to make their owners happy. Edge is delighted when he meets a very special Classic-type Sans named Sans (okay, not very creative) but is disheartened to learn that his owner, Papyrus (while great at showing his love) isn't giving Sans what his species needs to live long and healthy lives. So, Edge takes it upon himself to educate Papyrus on proper Sans handling, as well as letting him know that his Sans needs to breed soon. Conveniently enough, Edge has his own Sans (a willful Fell-type named Red) that would be the perfect mate. That is, if Sans will accept him.

    Summary

    Nightmare isn’t used to asking for help, it’s not like he’s ever received it when he had asked; but his crew is hurting and dying, and when backed into a corner he’ll do whatever it takes.

    Sans and his mages haven’t really signed up for this crap, until they do.

    Summary

    Kinktober 2021 is here, and so are some horny skeleons!
    --
    the reader can be male, female or unspecified (based on the chapter you are reading of course) :D
    -
    There is absolutely no rape or dub-con, there may be con-noncon.
    --
    All the characters are based on my versions, such as the 'home for lost souls' boys or the 'a tyrant and an addict'. even the AU's that aren't in the canon story line of either of them, because this is a spin off series and not at all canon to my previous works.
