Requested by kristinaSansKF (guys i think her account have been remove. I cannot see her account anymore and it always says user not found)
(Y/n)'s P.O.V.
It's been one month since I have been kidnapped by Sans. The police have been searching for me however, found no clue whatsoever of my location. I have been chained on a chair will the T.V. is turned on(kinky. no no haruhi control yourself XD). It's been awhile since sans visited me in this room; usually he would come here every two hours or so. The door was suddenly smashed into pieces as I saw Sans smiling at me with a hintof burning desire in his eyes.(it's happening guys *slaps myself* control yourself haruhi control)

"Ohh, (Y/n) my cherry lollipop I have great news!" Sans smiled. (Pls bare with me with the nicknames i was very hungry for sweets at that time when i made the nicknames.)

"Let me guess you finally found a way to make me love you." I said in a sarcastic tone.

"Oh.my.gosh. (Y/n) my candy coated sugar cane you guessed it right! We are really meant to be lovers!" Sans exclaimed.

Sans hugged me tightly around my chest. It was very uncomfortable for I'm still fucking chained on the chair! I suddenly felt a slimy tendril slithering around my neck. I instantly shooked out of the hug.

"What the fuck was that for!" I shouted. I heard him snickered.

"Hehehe, well you see I saw my dad's research and he found a way to make you mine." Sans' eyes burned brighter with desires while I felt his breathing getting heavy every passing second. "You see, in order for you to love me, first, I must put my 'love' inside of you so my magic will active." Sans said mischieviously.

"What do you mean by activated?" I asked. The room was silent for a while until Sans started laughing.

"Well you see, once I put my 'love' inside of you, I can manipulate your memories." He said as his eyes glowed with lust.

Unexpectedly, Sans roughly pulled me into a deep passionate kiss, exploring every inch of my mouth. He started to twist and suck my tounge which cause me to moan.'Damn, for a pyschopath he's a great kisser!' He stopped kissing me and started licking and nibbling on my neck, trying to find my weak spot. I shuddered once he found it. He notice my reaction and smirked. He bit myweakspot which caused me to bleed a little. He started to lap the blood on my neck. He stopped and admire the hickey he made on my neck.

"Well lets begi---" *megalovania ringtone* he was interrupted by his phone ringing. He answered the call." What! Oh, Papyrus what do you need?" His smile started to turn into a frown as he listened. I couldn't hear that much so I decided to ignore the conversation for a while.

"What happened? Was that Papyrus?" I asked.

"Well aren't you eager huh, (Y/n)-senpai." He teased, slowly going out of the room." Lets do this later, babe. For now, I have to get rid of this threat." He teleported out of this place.

I felt the chains loosen abit after that unwanted passionate kiss.... wait that wasn't a passionate kiss he basically tounge raped me! I looked down and saw that the padlock was gone. Huh, he must have planned this, but then something went wrong huh. I managed to shake free from the chains. I was about to make a run for it, but I immediately fell down on the floor.

"Crap! Come on legs, work goddamit! Work!" I shouted.

After so many attempts, I could finally stood up. I quickly dashed out of the room through the dark corridors. There were so many halls leading to different places that I almost lost my determination.

"This will take a long time before I can even find the exit." I sighed and started walking to another corridor.

Sans' P.O.V.
I started walking towards my house, furious at my brother.'Goddamit Papyrus, why won't you quit! I have no choice but to kill you if this goes on!'

~~~~~~~~Flashback *During the call*~~~~~~~~~~ ♡.♡
"Hello! Oh Papyrus what do you need?" I asked.

"Sans, I think that I, the Great Papyrus, found a clue on the whereabouts of (Y/n)!" He said proudly.

"Bro, I think you should give up. It's been almost a month since (Y/n) went missing. She might already be dead." I argied. I was panicking for Papyrus is on my tails and he won't stop.

"Sans, I can't give up!" Papyrus said in a stern voice.

"Why?" I asked.

"Well might as well tell you." Papyrus sighed. "I'm in love with (Y/n)." My mind was about to explode from anger and insanity. A moment of silence on the call. "Everyone is here and we need your help Sans." He said.

"Okay, I'll come over there." I replied. I ended the call.
(Okay guys I had this idea where sans sometimes misheard stuff cause he is love struck with you readers.)
"What happened? And why did you stop?" (Y/n) asked.

"Well aren't you eager huh, (Y/n)-senpai." I teased. I slowly went out the room. "Lets do this later. For now, I have to get rid of this threat. I teleported out of the room and went to Snowdin.
~~~~~~~~~End of Flashback brought to you by Lazy author~~~~~

I was standing in front of the house . I decided to plat it cool and opened the door. I saw everyone in the living room. 'Hmm, maybe I should kill them right now. I won't let this opportunity go to waste!'

'Hey, Sans, I haven't seen you since---!" I interrupted Toriel with a bone impaling he chest.( hey this is a yandere story so expect dwath i forgot whoops). "S-Sans why?" Toriel  asked before she turns into dust. A moment of silence in the living room. I looked around and saw everyone was preparing to attack me.

"Everyone, attack him." Undyne yelled. Everyone charged at me. I summoned my two gaster blasters.

"Sorry everybody, but goodbye." I apologized before I blast my two gaster blaster. Everything went blurry.

(Y/n) P.O.V.

It's been a while since Sans left. "I can't take it anymore!" I screamed. It echoed along the hallways.

"Tsk, tsk, (Y/n) you've been a very bad girl." Suddenly the door opened behind me. Sans is just behind the door. I started to run further away from the door until I felt a sting on my back.

"Fuck!" I shouted before I fell down on the floor.

"Hehe, I think you need a PUNishment." I heard him chuckle before I fainted.
