Demons Love [Underfell Sans x Demon-Reader]

Dating Life (Part 2)

Sans POV

I stayed in Y/N's room for awhile just to make sure she was actually asleep and not just closing her eyes.  I poked her every once in awhile to see if she would flinch, I poked her one last time and she didn't flinch, she finally fell asleep.  

I left her room and left her door open, my room was the one right next to her's.  I flashed backed to the time when I was thinking about sharing a room with her, then I thought it was best to take things slow, even though it has already been two weeks.  I didn't know if Y/N wanted to share a room, but I just went with my brain, and my brain said give her the master sweet.  It's nice being a couple, but something feels . . . wrong, I can't find out what's missing.  Maybe I'm just troubled with her pass, well . . .  I'm dating a demon basically, but Y/N said to never mention her old identity.  I'm not sure what was missing, but it was bothering me.  I went to my room and lay on my bed, but my eyes refused to shut, I couldn't sleep with all these stupid and deep thoughts stuck in my head now.  Then I realized, we actually never had our first kiss as a couple.  Great . . . I'm thinking like one of those cringy romance stories.  Sure we went on lots of dates (thanks to Amy and Mettaton), but we never actually slept with each other or kissed, apart from that really long time ago when we danced.  After thinking about all the cringy romance shit, I fell asleep.

Next Morning!

To my surprise I woke up quite early, 8am to be exact, it might not be that early but it's early for me.  I went to check if Y/N was awake, it turns out she was already awake and fixing her bed.  "Morning Sans!"  She said as she folded her blanket.  "Need any help?"  I asked "Nope"  Y/N always refuses for my help for some reason, I guess she's just one of those types of girls.  She finished up cleaning and went to the bathroom and brushed her teeth.  "Are you just gonna watch me get ready all day creep?"  She said.  I said a simple nope and went downstairs for some breakfast.  Inside the fridge was a bunch of leftovers and microwaveable food, then there were Temmie Flakes . . . Y/N's favorite cereal that she eats everyday for breakfast, so I though I would hide it from her.  She came downstairs and went straight towards the fridge.  I sat down as I watch her search the fridge.  "Looking for something princess?"  "Yeah, I swear I saw a box of Temmie Flakes last night, unless I was hallucinating . . ."  She continued to search the whole kitchen, but I his the cereal behind the television in the living room.  Finally, she sighed in defeat, but then her eyes sharpened as she. . . . sniffed the air?  "You okay there Y/N?"  She didn't respond and continued sniffing the air, she was getting closer to the cereal box, until finally she found them.  "You can't hide them from me Sans"  She gave me a little smirk before she left the living room to make her breakfast.  It's either she has one strong sense of smell,  or she has some weird connection between her and the cereal...

Your POV

How dare he hide my food!  Little rascal, why am I calling him little, if I'm like 1cm shorter than him?  I tried to shove the cereal in my mouth without milk or a spoon because I was in a rush.  I was suppose to babysit Frisk today with Sans because Toriel was going on a few hour trip to somewhere.  I always thought that frisk pretty responsible on her won, but eh.  Sans came into the kitchen and sat across of me with a bottle of mustard.  So I don't like mustard, but Sans is always trying to sneak mustard into my food so I would eat it, but I have been watching him this time.  I stared at him as I chugged down a box of Temmie Flakes.  He didn't seemed to make any movement to put mustard into my food for some reason...  I got to the bottom of the box where I found a plastic pouch with the label sugar.  Temmie Flakes always comes with a pouch of extra sugar.  "I can't believe I forgot the sugar packet!"  I just shrugged and decided to just east the sugar.  I opened the packet and dumped into my mouth, but instead of eating crunchy sugary sweetness, I got the horrid taste of .  .  .  .  .  MUSTARD.  "YOU RIGGED THE SUGAR!"  Sans laughed as I spit out the mustard, that little bastard!  I jump out of my seat and pushed Sans.  "Gotcha this time Princess!"  "You Will Pay!!!!!!"  I shouted as I threw the box at his face, he used the mustard bottle he was holding and squeezed it at me, so I grabbed some sugar from a cabinet and poured into his eyes.  He backed off trying to get it out as I laughed at him, I ran upstairs into the bathroom to take a bath.
