Undertale. Reader X Papyrus

(Random narrators POV again)

You and Papyrus walked out of the bathroom, looking like nothing had happened. Remember when I said that Papyrus was fast? I meant it. He was fast. "That was fun! Yeah, it was....we should get back before they hit the piñata! Hop on!" You jumped on his back and he ran back into the room to see that everyone was there. "And where have you two been? We ran around the entire castle twice! We went in every room! TWICE! Oh....good for you?" You laughed. Papyrus had come up with that lie, so that Sans wouldn't flip the fuck out.  Sans sighed and walked over to Wynter, who was playing with the kids. "Heh....I think that their kids will enjoy having a cousin or two! Yeah, probably! But....we better make sure that Callie doesn't get too close when she's playing....definetley." You hopped off of Papyrus' back and grabbed his hand, pulling him over to Asgore, jumping up and down excitedly. "When do we get to break open the piñata? Oh, in a few minutes actually....um....where have you been? We ran around the whole castle twice! Heh heh, I used to do that when I was young,it never ceased to amuse me! Oh, by the way, there's somebody here that wants to see you two, he's out in the garden! Okay?" You grabbed Papyrus' hand again and he led you to the garden."Hello." You heard a voice ring out in your head and froze. You slowly turned and so did Papyrus. What you saw was....strange, to say the least. It was a man? Skeleton? You weren't really sure. He was wearing a black coat that made him look like a blob of black stuff, one of his eyes was shaped like a crescent, the other one circle, and he had cracks in his skull You squeezed Papyrus hand a little tighter. Papyrus squealed and hugged the blob thingy, leaving you to stand behind him confused. "Father! ........father?" Papyrus pulled you over to the thing and smiled. "Yes ______! It's my father! You are Papyrus' girlfriend, am I right?" You nodded and smiled a bit. "Yes sir I am. It's nice to meet you....um.... Gaster, W.D. Gaster. Oh, nice to meet you Gaster! I'm _______."

You, Papyrus and Gaster all talked for a bit longer before Gaster said that he had to go. You smiled and hugged him. "Goodbye Gaster, I hope I can see you again sometime! Goodbye _______.....treat my son well, okay? Don't worry, I will." And with that Gaster disappeared. "Well, he was nice!" Papyrus smiled and leaned down, kissing you, and you gladly returned when-" Hey, are you done yet? It's time to break the piñata! Oh....did I miss something?" You pulled away and laughed. "No, nothing at all, come on Paps, it's piñata time!" You grabbed his hand and ran with him. 'Don't leave him ______, he has never been this happy before....I think you're the best thing that's happened to him." Gasters voice ringing through your head filled you with determination....to help Papyrus DESTROY that piñata!
