"Promise Me You'll Come Back" ( Undertale!Sans x goddess reader )

Reunited Finally Pt.3 of 4"Papyrus and a child?"

Sans Pov:
"My brother would like to see someone like you,because he's been down lately and I think seeing you will brighten up his day cuz you sure did with mine (y/n)" I say with a smile and I noticed a blush on her (s/c) cheeks. So adorable...Her face lightened up with that big smile saying "I.Would.Love.to. That's one of the reason I'm here...." She looked down muttering the last part. "Are you okay (y/n)" I am a little worried "I- I'm fine" she gave me a sad expression. I'm not buying it "(y/n) what wrong I know that face so tell me" "well I want to show you something later when we meet Papyrus and stuff" he tilted his head in confusion "well okay?" (Y/n) looked me in the eyes and said"Alright then and you can't tell anybody you have to promise me Sans" now I was suspicious of her "....I don't like making promises but for you....I promise (y/n)"Then (y/n) grabbed my hands swinging me around like a little kid does with a doll "Yay! I get to show later! " "(y/n) I'm getting dizzy now" "oops sorry" and she put me down. 'I wonder what she's going to show me later'

*Time skip brought to by Memes* XD

(Y/n)'s POV
"SANS! IS THAT A HUMAN?" A tall skeleton with a battle body and orangy/red scarf and boots,practically yelled with excitement evident in his voice."nope that's a rock" Sans said casually "OH" The tall figure said sounding disappointed 'Really Sans,really am I a rock to you?! I DONT EVEN LOOK LIKE ONE!!!' My mind screamed with my eye twitching, Sans noticed and was about to laugh"But what's that i-in front of the rock?" '....wow....just wow Sans' I started to laugh a little myself."OH MY GOSH?! IS THAT A HUMAN WITH CAT EARS?" I nodded happily THEY'RE SUPPOSE TO HAVE CAT EARS, RIGHT?" "Only the extraordinarly beautiful ones" Sans said with a wink followed by a hue of blue on his cheeks(see what I did there it rhymed) felt my cheeks heat up.Most likely putting red roses to shame "WELL SHE IS BEAUTIFUL."the tall figure said "Aww thank you umm...what is your name" I said nervously "I AM THE GREAT PAPYRUS BUT YOU CAN CALL ME PAPYRUS! WHAT IS YOUR NAME?"

"(Y-) (y-n)" I said neverously I put a hand out so he can shake it and he did. "WELL (Y/N) Continue ONLY IF YOU DARE,NYEH HEH HEH!" he yelled Running as his loud voice echoes through the frozen forest. 'Aww that's adorable' I thought as I looked at Sans who was.....blushing for some unknown reason, then he said "See I told you he'd be happy to see you (y/n)" Sans said smiling. "I honestly am not surprised" I say smirking "Well he's straight ahead this path,see you shortly (y/n),I'll keep an eyesocket out for ya." he said smiling. "Alright Sans see you in a little bit." I said waving and in a second he dissappered in an instant. 'Hmm,okay I might as well keep going so I can show them the surprise later' I thought skipping/walking to the next challenge that is ready for me. (A few minuets later)

As I continued up the path I so happen to hear the skele-bros conversation-" YOUR SO LAZY, OU WERE NAPPING ALL NIGHT." Papyrus belowed."I think that's called, sleeping." Sans said causally "EXCUSES, EXCUSES" Papyrus said as I stepped up to a square shaped hole in the ground. '?.What's this.' I thought literally having a question mark hovering over my forehead, until.... "OH-HO. THE HU- I MEAN (Y/N) ARRIVES" he said smiling enthusiastically.'This is adorable' I thought internally squealing "IN ORDER TO STOP YOU...ME AND MY BROTHER CREATED PUZZLES...I THINK YOU WILL FIND THIS ONE QUITE SHOCKING!!!" "FOR YOU SEE THIS IS THIS INVISIBLE ELECTRICITY MAZE" I started to laugh... "WHEN YOU TOUCH THE WALLS OF THIS MAZE, THIS ORB WILL ADMINISTURE A HEARTY ZAP!" I started to laugh uncontrollably. "P-PAPYRUS YOU SAID ANOTHER P-PUN" I said laughing. He slowly turned to Sans trying to look scary but Sans started to laugh also. "SANS! YOU TANTED ME WITH OUR TERRIBLE PUNS!!!" "Well they are...." "WHY DO I GET THE FEELING-" "Quite TEAR-ABLE" Sans said holding a paper ripping it in half,both of us falling on our backs. On the other hand Papyrus is like this:

Me and Sans continued to laugh so loud I think Toriel herself could hear us from the Ruins.  "OKay-okay.... I'm done laughing, sorry papyrus I couldn't let that one go. I said bowing down slightly. "THANK YOU (Y/N) Now.... Where did I leave off..." He said fidgeting with the orb. "OH YEAH IF YOU TOUCH THE WALLS YOU WILL GET SHOCKED BY THE ORB. SOUND LIKE FUN? BECAUSE! THE AMOUNT OF FUN YOU'LL PROBOBLY HAVE, IS ACTUALLY RATHER SMALL I THINK" he said unsure.I am a little worried to...say the least. "OKAY YOU CAN GO AHEAD NOW. " he said putting the orb away."Umm okay... " I took exactly Three steps and *Zap* "FGTYJGHJNFRTRTJFGKY"  I waited for the impact... But it never came.... Then I look up at Sans and Papyrus. 'OH..... " It looks like he got zapped when I touched the wall. "Oppps." I said nervously shrugging my shoulders. "SANS WHAT DID YOU DO?!" Papyrus said stomping his foot angerly, but me both knew he ment no harm."I think (y/n) has to hold the orb." sans said staring at me."OH, OKAY" then Papyrus walked through the invisible maze leaving a trail back to where he and Sans was."HOLD THIS PLEASE" Papyrus throwing the orb in the air landing on my head, as he quickly ran back."OKAY TRY NOW"'Seriously welp when life gives you chances...you take them' I thought as I followed the tracks and completed the puzzle with ease.  "INCREDIBLE!!! YOU SLIPPERY SNAIL!!! "YOU SOLVED IT SO EASILY...TO EASILY. HOWEVER THE NEXT PUZZLE WILL NOT BE EASY. IT IS DESIGNED BY MY BROTHER SANS.YOU WILL SURLYBE CONFOUNDED. I KNOW I AM! NYEN HEH HEH HEH HEH!" "hey thanks (y/n)  you're doing great oh and you know that outfit he's wearing, we made that a few weeks ago at a costume party. E haven't worn anything else since.....keeps calling it is 'battle body' man. Isn't my brother cool" "yep he sure is a jumping bean."  "Yep he's a hand full alright."  "So was this new puzzle you have designed for me?" I say smirking "you'll see." He said about to teleport "wait!" I blurted out slightly embarrassed "yeah what's up" I outstretched my arms twords him "Can I get I hug? " I say smiling "Umm, sure...ya didn't have to ask (y/n)" Sans said walking up to me."YAY HUGS"  I hugged him tightly. He instantly hugs back, with a hint of blue on his cheeks.When he let's go I can't help but feel slightly disappointed. "Well see you shortly" He said walking away "I know you are" I say smirking "*scoffs*I am a offended" Sans said pretending to feel hurt"No your not 'offended' your Sans" "pffff whatever (y/n) see you later" He said teleporting away.  I CONTINUED down the path wanting to see what lies up ahead.

??? P.o.v

After I've fought and "spared" Toriel I walked up the path, where I'd usually meet Sans.....I walked up to the bridge
.

.....

...............

.................

.............
*But no one came*

  "This.....isn't normal,I would usually meet Sans here what happened.....unless someone already came here." I mentally freaked out for a few seconds later I found tiger tracks?  "I guess I was right. now......back to unfinished Buissness. I said as I laughed like the killer I am(Back to you and the gang)

(You already fought Papyrus and won of course and now your friends)
"I'm so tried after that battle" I said face planting in the cold snow without a care in the world. "OH NO IS (Y/N) ALRIGHT" I heard papyrus yell "No she's fine just sleepy" I nod with my face in the snow.I heard footsteps aprooch my way. Then an unknown force picked me up. "(Y/n)  is not here she is temporarily visiting sleepy town she will beack in *yawns* 10 hours." I said "I got you kiddo, Come on Papyrus let's go home" "OKAY-" "shh" "okay"

Sans pov.
'Welp.it's been a long day today...'  I thought as I looked up at the redwood trees in the forest. Then I look back at (y/n) she looks so adorable....wait, what...!!!..........I felt my cheekbones become engulfed in a flame. "Sans are you alright your looking like...are you sick?!" Papyrus whispered loudly "......n-no I'm fine look let's just go home,  I said turning my head the opposite direction.  "OKAY" Papyrus said running off then I looked at (y/n) again and sighed sadly.

"IF ONLY SHE KNEW......"
