Yandere Sans x Reader

Chapter 11 G@$t€r?!

Hey guys, sorry for that last chapter. If you actually liked it, comment on this little paragraph saying you did. I'll try to respond to everyone. And oh my gosh the support is fantastic. I'm almost at another milestone! This is fantastic! Thank you guys so much. And anyway, on with the story.

Yeah, so our guest will be coming soon. You should get changed into something different. Paps and I'll get changed. He'll be here any minute.

Okay sans. I'll be right back!

Heh. She's so cute.

You ran upstairs to get dressed. Sans and Papyrus had gone shopping earlier for some clothes for you, and luckily they all fit. You settled on a nice outfit, skinny jeans with a long sleeved flannel shirt. Your socks were a bright pink color to match your hair. You had recently dyed it with some temporary dye. The neon green sneakers you chose were a little big, but other than that were perfect. You were ready for the guest to arrive. Well, almost. You grabbed Papyrus' hair brush(Why does he even have that?)and ran it through your hair really quick. You put on a golfing hat, cuz there wasn't any other hat, and headed downstairs. You heard muffled moans and creaks coming from Sans' room, but chose to ignore it. You flopped down on the couch and flipped on the T.V. There was just reruns of MTT show. You had seen them already. Sans and Papyrus came down, Papyrus looking happy and Sans looking blissfully tired. He flopped down next to you, and layed a kiss on your forehead. You giggled and snuggled up to him. Papyrus Sat down in the corner like a puppy, watching you two.

Sans?

Yeah kiddo?

Why is papyrus acting like that?

Cuz that's how I trained him. He was being a bad boy, but now he has to obey me, or he doesn't get to eat, sleep, sit down, rest, fuck, or anything really. He would just be tied up in the middle of the shed, not being able to do anything. Right Papyrus?

Sans' voice was a tiny bit threatening. Papyrus gulped down a huge breath before answering.

Y-YES MASTER. I CANNOT DO ANYTHING UNLESS YOU OR MISTRESS TELLS ME TO DO IT.

Good boy.

(I decided to throw in a bit of behavior like swapfell. Cuz why not. I'll be including so many au behaviors I'll lose count. I might never finish with this story.)

The doorbell rang, and something could be heard outside. It sounded strange.

Papyrus, go answer the door. If it's our guest, let him in. If not, tell me.

YES MASTER.

Papyrus got up and went to the door. He seems eager to please his master.

Ahem, masters.

Ah, that's right. Masters. Sorry Sans.

You better be.

Sans? Who are you talking to?

Nobody you need to worry bout, sweetcheeks.

Ok.

You snuggle up to sans even more. Papyrus let the person in. It must be the guest.

Ah, there he is.

Sans gets up to hug the....blob? It seems like a blob of tar with a disfigured face and holes in dismembered hands.

S-sans?! Who is that?

This? Oh, this is my dad, Dr. W.D.Gaster. Dad, meet Frisk. She's the human I was telling you about.
