Yandere Blueberry x reader (LEMON)

No....

Blue summoned a sharp bone in his hand... He started laughing like a maniac! His left eye glowing a light blue.. His pinpricks hearts, RED hearts like blood... I was trembling in fear..My dreams..? They were a warning, a warning blue was going to hurt us. His right eye still has a shadow cast over it while he runs to Papyrus' bed. He grabbed my arm and threw me off of the bed and into a wall, who knew he had so much strength. My body still sore as I tried to get up. Sans lunged at Papyrus with the bone in hand, landing on his ribs Papyrus yelped in pain. Sans' laugh only got louder... I got up and ran for him until he stabbed Papyrus' chest just barely missing his soul.. "GAHHHHH!!!!" Papyrus screamed in pain my body frozen I could feel tears pricking my eyes threatening to fall. Sans took the bone out of Papyrus only to stab him there again..and..again.. I need to do something! " SANS!! PLEASE!! S-STOP!!" The tears finally falling staining my cheeks. Sans only stopped the bone about to hit Papyrus. He turned to me.. "sorry angel, no. can. do...!" He lifted the bone above his head and laughed again. I ran to him grabbing his arms, I saw a S/c heart in front of me slowly turn blue. I was picked up now levitating I couldn't even process what happened in time before I was sent flying at an inhuman speed towards the wall. My back smashed against the hard wall causing it to break bits of it off. The wall now had many cracks in it from my body. I watched as I opened my mouth and a small stream of blood fell out and on to the floor. I tried to move but felt my body go limp. I saw Sans throw the bone up above his head again only to come crashing down on Papyrus' chest. Papyrus' screams filled the room as did my loud sobs, and Sans' laughter. Where's MY Sans? My innocent blueberry cinnamon roll? Was it all an act? No, it couldn't have been, no one could act that genuine. Then why? Why was he doing this? Why is he giving Papyrus no mercy in stabbing him? Blood gushing out of my head and a little out my mouth. While Papyrus had bone marrow and blood falling on the bed and Sans staining them. I used the last of my strength to stand and walk over to them holding my head as I was getting a migraine. I tried my best to be silent. I lunged at Sans knocking him off Papyrus and onto the floor. I landed on top of him crying my eyes out "STOP IT! please-... Sans.. please..He's your brother.." He only looked at me with a face that says 'Your point?'. He growled a bit. "Does it LOOK like I care?" he said in a monotone voice. I felt my soul start to turn blue again, he whispered something to me before I was sent flying into the wall again..."Sorry Princess.." My eyes wide. "No San- AHHHHHHH!!!" I was sent into the wall with more power this time. I hears Papyrus' extreme cries of agony, you could even see it plastered on his face. All I could do was let out small whimpers, I found my way to my hands and knees crawling towards sans who was ripping off Papyrus' ribs one by one. I grabbed sans' ankle and with the last of my strength I pulled him down and jumped on top of him. I wrapped my arms around his chest and dug my face into the crook of his neck. "S-...Sans...*cough* please sans..." I couldn't help but cough inbetween my words I was coughing up blood, some onto the floor but mostly on Sans. I could feel Sans tense up everytime I showed I was in pain. He grabbed my arms and took them off of him sitting up on his knees he placed my head in his lap. He sighed petting my head slowly and comfortingly I only let out small whimpers and started trembling. My face was stained with tears that were still going down like a water fall, my eyes were puffy from crying so much. Papyrus' low whimpers and wincing could be heard in the background.. Papyrus is strong...He's still on five HP.... Sans grabs under my armpit and lifts me up more so now i'm in his lap. He's placing soft kisses on my head and muttering somethings I can't hear. Thats when it took me...the sweet release of sleep...? Death..? I'm not sure, maybe i'll finally wake up from this nightmare..

I woke up in Sans' bed relived it was only a dream. I sat up to check my surroundings but immediately fell right back down due to the sharp pain in my head and my back. "S-s..s...Sans!" I cried out.. It was a low raspy voice that came out of my mouth like it had been strained by crying.. I heard loud footsteps haistly making their way to me until Sans burst though the door. "Sans? W- *cough* what h-happened?" I looked up weakly at him he only smiled back in response. He walked over to my side laying his head on the bed " I had to get rid of something and you wanted to keep it so I acidentally kind hurt you a bit.." He looked and sounded ashamed of himself "w-w-what??" He tensed up and looked as if he was gonna cry to which he did "I-I-I... I DIDN'T MEAN IT I SWEAR!!" He cried. I slid to the side a bit and patted the bed next to me he hopped up and wrapped his arms around me crying into my chest area. "s-shhh..i-it's ok! I-i-i'm fine!" I tried to reasure him he looked up and into my eyes for a minute shaking his head and crying even more, only now I noticed his tears were the same color as his blush and eyes. 

It's been a few hours since I woke up and I am now sitting on the couch with Sans. We chose a corny romcom to watch, something with either roses or petals in the name. The living room was dark only eliminated by the large tv in it. Sans was sitting next to me as my head was leaning on his shoulder. The romcom had finally gotten to the romantic part where the two main characters kissed. Sans turned to face me face as blue as ever... He really is my blueberry.. He lifted a gloved finger to his cheek and tapped it, I know what he's getting at here! I lift myself up enough and kiss his cheek softly. I sit back in my place smirking at Sans tapping my cheek like he did his. He placed his cold teeth on my cheek his face becoming even more blue. He tapped his cheek again so I readied my lips next to his cheek leaning in..only..not to meet his cheek.. He turned his head in time to kiss my lips.. I was shocked so shocked I didn't move.. He parted our lips and smiled at me, a soft smile.. I love his smile.. 

We finished the romcom and finally went to bed.
