Let's Do This! (Underfell Sans x Falcon Reader)

This was requested by my a friend of mine who likes to go by Error~chan.

Sans' Pov
I was just walking to my sentry station mumbling some swears secretly at Papyrus. Today that asshole hit me upside the head for sleeping. Dear god I can't get one bit of sleep can I? As I sit down at my sentry I hear rustling from the bushes. I look down to see a small little bird. I then bend down and pick it up. "Hey little guy. Heh, no one wants you either do they?" I asked the little chick. It shakes its head. "You're smart ya know that?" I ask it. It shakes it's head. "Lets see are you a boy?" I ask the bird. I shakes it's head 'no'. "So you're a girl?" I question. It then puffs out its chest and nods. "I know I'm a fucking idiot." I tell her. She nods. "Hey! Quite being so honest." I growl. She gives a little squawk. "Heh I guess so let me guess your brother/sister pushed ya out of the nest?" I question. She nods. "Heh same, my bro doesn't want shit to do with me." I laugh. She the nuzzles my chest happily. "Ya know, ya need a name, how about Mist?" I asked and shakes her head no. "How about Y/n?" She gives a little chirp.

3rd Person Pov
You and Sans were epic together, and you started to protect him from danger and Papyrus.
Your Pov
Sans wants me to meet the human Frisk. Like hell that'll happen. I've never met a human so sure I guess. Sans came in to his room surprisingly quick. "Sans what's wrong?" I asked him. "We're moving to the surface!" He says growling. "Oh, really? Why?" I ask cocking my head as he slowly walked over to me. "Apparently the human broke the barrier and got the king and queen's kid back." He says sitting on his bed petting me. "So we're leaving the Underground?" I question. "Yeah, you ready?" He ask. "Yep just get your glove cuz I don't want to claw your bones again." I growl ruffling my feather. "Okay okay, don't get pissed at me." He chuckles putting on the glove and putting his arm close to me. I happily grab on. We then leave the house and head to the king's castle. Once we get there I see Undyne, Alphys, Toriel, Asgore, Papyrus, and the human. I give a little squawk signaling we're here. Everyone turns there attention to Sans and I. "Y/n must you do that?" Sans ask. "Yes because I am the definition of an annoyance." I say proudly puffing out my chest. He starts laughing. Sadly though only Sans can understand me. Papyrus gave me a dirty look causing me and hold tighter onto Sans' arm. "Hey, Y/n losen up would ja," Sans says softly. I losen my grip a bit. The human the runs up to Sans. I give him a confused look. "Hi, Sans!" The human shouts. "Hey, kiddo ya did a good job." Sans says. "Thanks, now let's go!" They shout and run up. I the decided to fly. "Whelp lets see this shall we Sans?" I ask him. "Yeah, here ya go." He says lifting up his arm so I can take off. I jump from his arm and flew up doing a little spin. As everyone walked together, I flew over them, watching. As we made it to the edge I slowly flew down to Sans. He held his arm up. I carefully landed on it. The human looked amazed at what Sans and I did. "You're a good bird Y/n, a very good bird." Sans says petting me. "Thank you Sans, but I'd have to say you're pretty clawesome." I reason. "Hehe funny bird." He chuckles as I nuzzle his skull happily.
