Au Sans x Reader Oneshots

How could you? pt.2

READ THIS PRETTY PLEASE: Okay, remember that heartbreak from Science! Sans? Yeah well fuck him, you're with another version of Sans in this one, I just don't like the thought of giving a cheater a second chance okay? This was inspired by another author I can't remember at the moment but they had Sans cheat on you and the second part you moved onto dating Papyrus, I think that's a very smart idea but since this is Sans x Reader, I'm putting you with a different Sans instead, you'll figure out it is soon, I'm sorry if you don't like the Sans I put you with, onto the one shot that I took forever to write!

Your Pov

It's been a while, a year to be exact, another human fell but they managed to free us, it was great, Undyne found a human girlfriend, I'm glad she moved on, for me now, I'm still a mess, I act like everything's fine but I still cry when I'm alone, pathetic right? I got an apartment on the surface, not far from where Undyne and her girlfriend lives, Sans and Alphys are still working on something so they got a bigger lab on the surface, good for them, I guess, we still have to check on them to make sure they don't kill themselves, Undyne shows off her girlfriend everytime we have to go check them, I on the other hand am showered with compliments from Sans and of course he's still apologizing and begging for me to get back with him, but screw that, once a cheater always a cheater, I bet they still fuck away all of their worries. Whatever, today, I shall hang out with Undyne and her girlfriend, I think her name was.... U/g/n (Undyne's girlfriend's name), she's real damn good at video games so we all play games together every week, but today Undyne called me as I was on my way to her apartment.

~Conversation~

Me- Ey Undyne, I'm coming over, about half way there now.

Undyne- You don't have to punk, they have a problem at the lab so I'm heading there and you have to come too sine you're an ex royal guard.

Me- Ah, I see, I'll see you there then.

Undyne- Later punk.

~Conversation end~

'What the hell did they do?' I think to myself as I walk past Undyne's apartment and to the lab, I arrive after 20 minutes and swipe a card to open the door, I walked in and I immediately hear chattering, I walk towards the voices and notice a bunch of other monsters looking at.... Other versions of themselves? My eyes scan the room as I finally see Undyne and walk up to her, even though there were two of them. "What the hell is going on?" I ask, they both turn to me, the other version looked like a scarier version of Undyne. "Well, they seemed to have bought another... AU? That's what they called it, in other words they bought another version of us here and they'll have to stay here cause they can't go back, only certain monsters are here, not the entire underground, the monsters that are here are me, Alphys, Papyrus, Sans, Asgore, Toriel, Frisk, Grillby, Mettaton, Napstablook, BurgerPants and Monster Kid, well, that's who I can see right now anyway." She said, I nodded and left her to talk to her doppelganger, I saw the other Papyrus, he was even taller than my Papyrus, and very rude, both Frisks were equally adorable, the other version had Flowey with them, he was nicer than our version, the two Toriels were talking about pie, the other Alphys was telling our Alphys about gory anime, the two Mettatons were posing, The Asgores were talking about something, I'm not sure, each monster were talking with their other version, but I didn't see any version of me, I kept walking around and observing the monsters until I saw Sans, both of them, they were giving each other death glares, the other one was wearing a black jacket with a red sweater underneath, his golden tooth very noticeable, he must have felt my stare on him from a distance cause he turned and looked at me, when we met eye contact, he winked at me, I blinked and he was gone, wtf? "Hey there, sweetheart-" HOLY MOTHER OF COW LLAMAS! I jumped at least one foot off the ground, I gripped where my heart would be and looked at him. "Dude, you almost killed me." I said while slowly gaining control over my breathing, he chuckled. "I'm sorry sweetheart." He said with his deep voice, it sounds rougher than Sans'. "The name's Edge, doll. Never seen ya in my universe." He said as he 'kissed' my hand. "Er, really? Well I'm Y/n." I said. "I would've noticed a hot dame like ya, hun." He said, still holding my hand. "You need to make up your mind on what pet name you're sticking with." I said. "Well, you're so beautiful I can't just stick with one." He said and winked, I blushed and looked away, just then, I felt someone grab my hand from his, it was Sans. "Asgore wants all the ex royal guards to go with him." He said while glaring daggers at Edge, I shrugged. "Okay." I said and pulled my hand away from Sans then started walking with Asgore and the other ex royal guards.
