Yandere Blueberry x reader (LEMON)

SwapFell

You awoke, to your surprise this time you could remember. You weren't tied up. You guessed this wasn't one of those cliché yandere stories you would read on the surface. Your eyes finally adjust to the light as you sat up seeing that you were in sans' bed. Fortunately for you, Sans was no where in sight. You pulled his covers off of you and slipped your feet onto the ground. You were about to move until you heard Sans' voice erupt from the darkest corner in his room "Ah~ ah~ ah~ Not so fast Y/n~" He purred. You cringed at the sound of his voice, his annoying ass voice.. How you had learned to hate it~ Sans' figure slowly emerging from the shadows, his pinpricks hearts, his clothes torn and covered in dust and blood, the way his cute smile had turned into a crooked grin. He held his hand out and said " Come here Princess~"  You shook your head and crawled back onto the bed, fear controlling your actions. His facial expression soon turned to a scowl at your actions. 

"Hey, hey, hey! I didn't want to do this! I didn't want to kill them All! Watch the life drain from their faces as I tore them apart bit by bit~... YOU DID THIS!! YOU MADE ME THIS- this-... THIS MURDERER!! ITS ALL YOUR FAULT!!" your face changed from a terrified witless expression to a grimace in seconds. You didn't do this right? What had you done? Sure, you'd shown affection to Sans and other monsters! But, you weren't doing anything wrong, right? You were lost in thought until Sans spoke "But, it's all ok~ I forgive you~ You gave me a new hobby~!" You flinched not knowing Sans was sitting right next to you smiling until he spoke. Your expression went blank. You slid off the bed and beckoned sans to stand up. Without a second to think, you punched Sans as hard as you could on his left cheek bone. You felt something sharp pierce your skin as you punched him. Sans fell back on the bed holding his left eye with a blank expression. You looked at your hand to see a small sharp peice of bone had been stuck in some of the soft flesh that was once there. Then you realized... Sans only holding his left eye.. Bone in your hand... You softly reached out and pulled his arm away from his face.. He had the bone chipped off his left eye.. Only a small scratch but still, your small frail hand chipped his skull. 

"You. little. BITCH!!" Sans grabbed your arm and forcefully threw you on the bed. He pinned you underneath him and opened his nightstand drawer. You didn't get a good look at what he did, until he used it to tie your hands and feet down to his race car bed. "Y/n. You've been a bad girl! And bad girls get punishments!" he declared. You didn't have time to react before his hand came hurling down onto your cheek.(the kind of cheek on your face! Bad girls don't get rewarded!!) You screamed in pain before he sent another slap to your other cheek. You squirmed underneath him as he kept slapping your face. You could feel a tear starting to build up, until you felt a hot stream of salty water start to fall from your ducts to the pillow beneath your head. The hot tears staining your now pale face, but, this stopped sans. He lowered his face to your ear " I don't want to hurt you princess~ Don't make me~!" He whispered. Sans flopped down next to you, arms around your torso as his legs were wrapped around your hips. He nuzzled into the crook of your neck, slowly falling asleep.. leaving you there.. alone.. in the dark and afraid.. 

A few days later~

Sans has been acting weird lately.. Obviously he was weird since he had killed someone but-.. This was different, he was avoiding you... He trusted you enough to let you roam around the house without him by your side now. But, every time you see him he's been reading books! Yesterday he read a book called 'Ecto Biology' what the heck is 'Ecto Biology'?? Ecto meaning: outer; external; on the outside? Was he researching somethings outsides? Hmm.. That's sounds... Interesting to say the least.. You also caught him reading 'Monster heat' What was that? Did he want to get one of the dogs down here as a pet? Would they even count as monsters? Did he kill them too? The dogs down here are the only things you could think of that could have heats. You would ask Sans but-.. Y'know.. He killed all of your friends and acquaintances.. and your love... You had been acting as good as you could lately seeing as you didn't want punishment. Sans had boarded up everything that he didn't want you getting to, including the front door and kitchen. He said that the kitchen had to many possible weapons you could use to damage more of him.. This just made you feel worse.. You didn't mean too! But, not meaning to do something doesn't mean you didn't do it... Sans had also been wearing different clothes now too! He wore a black crop top sort of thing, shoulder pad thingys with golden outlines, black shorts with a grey belt that have a gold skull and spikes on it, black arm and leg warmers, red high heeled boots and gloves, and his once light blue scarf red.. You didn't know if the red was dye or blood but you didn't want to test that theory... His pinpricks never stars anymore... This all made you want to cry... You wanted your blueberry cinnamon roll back!

You were sitting on the couch trying to find something to cure your case of boredom. Sans was sitting on the other side of the couch reading something, his face the same light blue it always was when he was flustered... You leaned down a little to see what he was reading it read 'How To Please Your Signifagant Other' Your face immediately turned into a tomato. Was Sans' interest in reading that book-.. You? Sans noticed your staring at his book, he smirked.
