Underswap!Sans X Pregnant!Reader 2

Okay... So I'm actually thinking of making a fanfic of this once I actually have the guts to finish my current ones. What do you guys think? Or I could just have this continue randomly as different parts. So, the next would be Underswap!Sans X Pregnant!Reader 3. There would just be more and changed detail in an actual lone fanfic. I don't know what to do ;-; PS the video is just a current obsession.

THE CONFESSION

Anxiety flooded through your veins as you waited for the symbol. Your 'leak week' hasn't come for almost two months now, but that's not the thing that scares you the most. Papyrus is. What would he do if he found out about you and Sans? Even just to kiss Sans in front of him would be asking for a bad time. Paps protects his brother with everything he has; he would easily choose Sans over you.

You sighed and rubbed at your temples. Just one more minute, then you'll check it. How would you even tell Sans? Guilt flooded over you as you realized what you have actually done. He was the most innocent creature you have ever known and just because of your impulsive nature, you took it away from him. So selfish.

During this time Papyrus had already been staring daggers at you. He would pull you to the side to warn you. "Don't do anything you'll regret." He would say. He'd hint that he knew more than you thought he knew, but that's impossible right? You spent all the time with Sans that you could, trying to be discreet about making sure he doesn't bring it up. Although you made sure he knew you weren't comfortable with anyone knowing.

"Why?" He asked one time. "Why would it be wrong for someone to know? Isn't it a good thing?"

"Yes it is a good thing... But... People are usually dating and... married before. We can say something some time but not yet. I'll tell you when." You soon ended the conversation. Although you can't keep the knowledge from him forever. It's now your responsibility. Something you are now not sure you're ready to share.

It's not that he's too young. He's actually older than Papyrus, who is definitely an adult. Sans is mid twenties maybe? He's just... naive? Though you aren't sure if it is his fault. Maybe one day you'll figure out his brother's secrets. Then everything might just make sense.

Swallowing, you turned the test and read it. Positive. Somehow, you're carrying a monster's child. The most innocent monster you know. Tears dripped off your face as you tried to mentally prepare to tell the father. Does he even know what he's done? Do you know what you've done? Your knowledge of raising even a human child is zero. Now imagine a father that doesn't even know where he came from.

Either way now... You have to tell Papyrus. If anyone could help you with this child it was him. Or... Undyne. A check up would be best. She could give pointers and advice. If only you could call her now. You looked at the time. 7:09 p.m. You dialed up her number on your smartphone.

*Ring *Ring- "H-hello?" Undyne picked up a little after the call went through.

"U-Undyne, are you b-busy?" You asked, your anxious stutter almost as bad as hers. Your voice didn't hide the fact that you're crying.

"No, w-what's wrong?" Worry could clearly be heard from her voice. More than usual anyway.

"Can I... Um... Is it too late to come over, I need to talk in person."

She agreed and you hung up the phone. It was starting to become late and you didn't want to burden anyone too bad. You grabbed the test planning to throw it away somewhere else, so you stuffed it in your jacket pocket.

You quietly snuck out of the bathroom, listening to make sure no one followed you. The moment you got outside you ran towards Gaster for a ride. Sans stopped you right before you got there. Your heart pounded louder than you thought it could, and you feared that Sans could hear it too.
