Forever together...Sans x Frisk fanfic

Can't believe it...

3 years have passed, Frisk went to university and then became a doctor, Sans helped her in anyway he could, he became a good scientist, but now Frisk discovered something...

Frisk's POV

Those three years were the happiest of my entire life, me and Sans found jobs for both of us...well, apart from us, Papyrus and Mettaton got married, even Alphys and Undyne! I got to see Mom, Dad and my dearest Chara and Asriel, and I'm really happy about that! Now I'm at hospital, I'm working, I really love my job, it's tiring me out sometimes, but I keep holding on...Gaster even gave me some hints to work, in case I would meet something strange in a patient...then I felt strange...I had to go the bathroom

Frisk: Myral, I'm going one moment to the bathroom

Myral is my assistant, she's very kind, and I trust her

Myral: Sure doctor

I quickly ran in the bathroom, and then I throw up everything I ate this morning for breakfast...weird, maybe I got near some virus and I got sick, well, that happened too when I was seven years old...Sans would tell me that I have to stay at home, and he would take care of me with medicine, tickling and watching films in the night with a mug of hot chocolate until I wouldn't fell asleep...well, I think I should rest at home, but first, I have to tell Myral that I'm going home...I returned in my office and found her writing on her computer

Frisk: Myral...

Myral: Umm, Mrs? Are you ok? You look like you're going to faint...

Frisk: Indeed...I think I got sick, I'm calling my husband to ask him to take me home, will you please take my place for visiting?

Myral: Sure Mrs.

I called Sans, and he responded immediately

Sans: Frisk? Are you ok?

Frisk: No Sans, I think I got sick, some minutes ago I even throwed up my breakfast...

Sans: Don't move, I'm coming!

I closed the call and sat down on my chair in front of my desk...I only have to wait for Sans

Myral: Mrs, can I ask you something?

Frisk: Go on...

Myral: Your husband is a monster right?

Frisk: Yes, why?

Myral: Well, sorry if I'm telling you this, but I heard that pregnancy between monsters and humans is very easy, it only needs to love someone with your entire soul and bam! You're pregnant!

Frisk: *cough cough cough* WHAT?

Myral: Sorry Mrs, I shouldn't have told you those things...

Frisk: No no, don't worry, I only mean, why should it happen only now? I am engaged with my husband since I was thirteen, why now?

Myral: It requires some years after the wedding...

Frisk: Well, I- I don't think it's that, I think it's something else

But then someone knocked at the door...I felt like I was going to throw up everything again so Myral spoke for me...

Myral: Come in!

It was Sans

My eyes lighten up...Sans ran in my direction and grabbed me by my arms

Sans: Frisk, how are you now?

I tried to gesture him that I'm not okay, I was trying to hold myself to not throw up, I think he understands and picked me

Sans: Miss, tell the principal that I'm taking Frisk home ok?
