Undertale Lemons or Smut

I fuck you senpai? (yandere us sans x reader)

Trying to think of a funny title.
(Y/n)'s P.O.V.
It's been two weeks since the Sans incident happened. I looked at my portrait of my friends and remember how they were brutally slaughter by Sans. I tried to forget the incident, but the screams of my friends permamently haunt me. I looked at the ceiling and re imagine the scene of the incident.

~~~~~~~~~~~in the past~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~♡♡~♡~♡~♡~♡~♡♡~~~
I head towards my locker and notice a piece of note stuck between my locker. I grab the note and read what it says.

Please meet me in the gym❤❤ (hart hart)

By your admirer.

Many people admire me and think of me as if I was sent down by the heavens. I was the "The Athena" of the school and it annoys me. I head towards the gym and notice something wasn't right. I looked at the window and notice all of my friends is tied around a pole. I quickly run towards them as fast as possible and tried my best to untie the ropes. I looked at them and notice them crying and shaking their heads, signalling me to get out. I grab my phone and dialed the cops. After I called the cops, I was suddenly pulled away from my friends and slammed in the wall. I fell down on the ground, unable to move, I looked up and saw something I couldn't believe, it was Sans.

Sans was one of the monster who was freed by the kid named Chara. He was enrolled in our school as an exchange student. He was an odd student not because he was a monster, but for his happy-go-lucky attitude. I tried to befriend him, however he somehows disappear before I could even talk to him.

Now he's here with my friends tied up and me, slightly injured. He pulled me closer as I whimper and scared to death by him. He made me look at my friends and shows the large knife on his hand. He slowly made his over to my friends as I could hear their muffled screams. I tried to crawl away, however I was stuck in place. Sans was just a few inches away from them. Within a second, he slice everyone's neck as if they were made of paper. Blood spilled all over the floor. I started tear up as I just watch my friends get slaughtered. Sans was walking towards me with a smile crept on his face. I tried to move, but something was grabbing a hold of me, making sure I won't do something. Sans lean closer to my neck, I could feel the heavy breathing around my neck. I was suddenly bite in the neck. I felt my neck gushing out blood

"I'll be back for you, My Senpai. Your my goddess."

By the time I was awake, the police was already here. The police couldn't find Sans anywhere and was declared a unsolved case. I moved away from my old town and decided to live on the country side. However, The last words I heard will forever give me fear.

I heard a knock coming from the door. I opened the door and saw a skeleton monster who seems to be wearing a girl sailor uniform. She looks a bit daze until, she speaks up.

"Hi! I'm Samantha and I'm happy to meet you my neighbor." She smiled as she hands her hand out.

I looked at her and couldn't help, but feel the eerie presence around her. I ignore her presence and decided to be friendly with her.

"The name is (y/n)." I greeted her while shaking her hand.

"So why so sad looking (y/n)." Samantha asked.

"Oh nothing. Just missing some stuff." I said.

I was suddenly pulled into a hug by Samantha, who's trying to cheer me up.

"My brother says a hug can cheer a sad person." She smiled.

I giggled at her and decided to hug her also. I guess I could start over.
