    Summary

    Sans is just trying to make an honest living by extracting scrap from the junkyard and selling it to the Royal Labs from a shady cavern in Waterfall. Now if he could just figure out why he constantly feels like he's being watched...

    Mind the tags, particularly noncon/rape and torture! This one gets pretty dark.

    Summary

    It was somewhat narcissistic, no? Falling in love with ‘yourself’? Silly. Of course you knew he was a different person, and that your attraction had nothing to do with appearances. It was about caring and protecting – your fucking old and annoying brother complex hitting again, throwing on your face how fucked up you were, but now with a different subject. You were able to keep your hands off Papyrus because you would never be able to touch something as pure with your dirty hands. But Red was diferent. He was already tainted, broken – more than yourself, no less. You’d take him to your lap every time he had a nightmare, just like you did to Papyrus when he was a small skeleton, but you knew that if you did this to Red, consequences would be different.
    And you knew he thought the same.

    Summary

    Sex.
    In human culture, it is both vilified as well as romanticized. Young people are both discouraged and encouraged to have it, and especially in a college party atmosphere, the mixed signals can be stressful.
    Then the monsters came to the surface, and from the other universes. It was never fully explained why or how, but it happened, and they were quick to stick together. Within months, Undertail University was founded by Dr. W. D. Gaster, and it gained a reputation as a thriving college atmosphere that boasted high graduation and success rates. It also boasted a very different view of sex, one that monsters had been entertaining for centuries.
    Somehow, against all odds and despite what people said, you’d applied.
    Somehow, you’d been accepted.
    And somehow, for some unknown reason...you’d enrolled.
    (Based on the headcanons of Skelltales and the #discordcrew on Tumblr, as well as some of my own. Written with permission.)
