    Summary

    " What..." You inhaled a deep breath through your nose, exhaling slowly out your mouth. "and I cannot stress this enough, the fuck. "

    It was in that moment Sans knew, he fucked up.

    "Well, ya see...princess..." he was hesitating to find the right words to say, and if the look on Y/N's face was any indication on his progress on doing so, he was failing horribly. Beads of sweat like magic started to form, dripping down his temporal bone. His perma-grin tight, he shifted his eye lights back and forth between you, Gaster, and the motley crew of skeletons that now inhabited the den.

    Summary

    Red appears in a strange world unlike his. Everyone says hi to him, everyone worries about him...and he can see the sun!! What was going on?

    It didn't matter. What mattered to him was keeping far away from Gaster...and keeping his baby safe.

    (A story that just wouldn't leave me alone, so I'm back, again, here, right now. Will include very much explicit sex scenes at later dates, and I'll put warnings up)

She hopes that with one close family of sisters can warm the hearts of these skeletal brothers into trusting humanity just a bit more.
    How will the sisters keep these monsters together in harmony when dealing with a dark trama they all secretly share? Find out!

    Summary

    Underswap's Gaster is not a Nice Monster. Not at all.

    Years of being alone have broken Blue, and only a fluke accident has him tumbling across the multiverse and landing smack dab in one of the ones you really don't want to be in if you're from a Tale 'Verse.

    Red knows the mask that Blue wears, so does Edge.

    Its the same mask they put on every day themselves.

    Summary

    Sans truly did not understand much at first.

     

    He didn’t understand the sudden absence during your secret nightly visits. He didn’t understand the frequent mood swings you experienced. He didn’t understand how hot your body seemed at times, yet how you weren’t sick. He didn’t understand how loud your soul would beat at times in cold, dead nights.

     

    Then it hit him like a brick.

     

    Of course!

     

    You are in heat!

     

    Wait…. That didn’t make sense. Humans don’t go into heat.
