A/N:

Hello everyone! My god it's great to be writing again. I've written stories before, but have moved onto a new account.

This one to be precise.

So, I don't want to take too much more of your time, I'm planning on keeping this story around seven chapters and you'll love what I have planned. Hope you keep an eye out for more of my updates! Also, if you can, feel free to leave a review in the comment section for support, it really helps with a gal's motivation and I love reading all of them, no exceptions.

Excuse any mistakes, not beta'ed

Cheers~

Admittedly, Sans wasn't easy to catch off guard. Yeah, he was lazy, but you spent the amount of days he had reliving countless resets, not to mention the Void… Okay, so you probably get the picture. Now, he's usually good at picking things up. Which made this little, heh, situation all the more unusual.

He gulped and shut his eyes, focusing on forcing the wave of possessiveness down so he could think sensibly. Alright, so this was definitely one of the longest runs he had gone without a reset and clearly should have seen this coming; however, his own golden-brick-trail thought process hadn't led him down this particularly screwy rabbit hole.

Breath in, breath out.

G-o-d-D-a-m-n-i-t.

In reality it took only a few seconds, but it felt like forever until his blood stopped boiling. Papyrus stood across from him, hurt and confused at his lack of response. That obviously needed to be quickly remedied. Sans made a pained-noise of sympathy and pulled Papyrus down beside him. His younger brother just collapsed into him, wrapping him up in long arms, dragging him close for comfort. Sans resisted snarling as his arms rubbed against the new harsh texture on his brother's bone.

His brother let out a pained whimper and Sans hand shot up immediately in search for his hand, clasping one between his own, he traced calming patterns.

"I DON'T UNDERSTAND SANS, THIS HAS NEVER HAPPENED TO ME?"

"well papyrus, there's really no excuse for it, you're way past the point from where I should've given you the talk."

The damned scales were beginning to flake off as he spoke too. Sans took the moment to scrub at Papyrus's bones, hoping they'd dissapear faster but was a bit too harsh. Papyrus retracted his hands with a wince.

"SANS?"

"alright, okay. so, you know how were like, the only skeleton monsters in the underground?"

His brother nodded slowly, he had wondered, but the question never crossed his mind at an appropriate time to ask.

"well, we're a pretty rare species for a reason. other species tend to, uh, stick to monsters that look like them. magic during reproduction works a whole lot easier that way."

"YES, I DO KNOW THIS BROTHER, BUT WHY THIS?" Papyrus gestured to the magic that had condensed onto his bones, forming bio-luminescent scales. Sans admitted it would've been pretty to look at if he wasn't peeved at how they got there.

He blushed, shaking the thought from his head, "well, we skeleton's have adapted a way around this, we mimic the traits of potential monster mates around us to make us more attractive." His brother stiffened and Sans quickly found that hand again before continuing, " i mean, the more we look like another species, the greater the chances they'll find us attractive, which means the better chance we have for continuing our species survival. our skeleton-ness is actually one of the most dominant magics out there. so, any product of a union between us and another species is absolutely guaranteed to produce only skeletons offspring, because of this, our magic doesn't discriminate when choosing a partner."

Papyrus froze, and took a shuddering breath.

"SO WHAT YOU'RE SAYING IS THAT DURING MY TRAINING WITH UNDYNE, THESE SCALES THAT APPEARED-"

"yup, that's nature call telling you it's time to bone."
