The Fallen Lovers (Underfell Sans x Female Fallen Angel Reader)

Alphyne

~~~~Sans' POV~~~~

I woke up realizing (Y/N) was laying on top of me. She was adorable when she slept. I hugged her around her waist, pulling her closer, and I started falling back asleep until I heard Undyne and Alphys burst through the door, jolting awake, but not enough to wake (Y/N). She's one heavy sleeper, but she woke up to Alphys fangirling shriek.

"S-sans?... What going on?...." She rubbed her eyes and looked at me, then looked at Alphys, basically telling her to shut up. Alphys stopped shrieking, but her expression remained. (Y/N) rested her head on my chest, trying to get comfortable again.

I glare at Alphys for waking (Y/N) up, she really didn't need to squeal like she did, because she gave me a headache. I noticed that Undyne grinning, but I frowned and flipped her off right before teleporting me and (Y/N) to my room. I set her down on my bed, but she wouldn't let go of my jacket, so I took it off and she instantly cuddled with it, making blush a bit.

I walked out to Alphys and Undyne, glaring at them from the second floor. "Why did you just decide to burst into the house and start screaming? Were you planning on waking up everyone in Snowdin?" I asked, completely and utterly irritated.

"No, but I'm happy we didn't, or at least you are. You don't want the entire underground knowing your relationship with (Y/N), now do you?" Undyne replied back wittingly, "But I'm just here to get Papyrus, he has guard duties. So where is he?!" Undyne practically yelled, obviously forgetting about (Y/N).

" Stop yelling, (Y/N) is sleeping, so be quiet, and Papyrus is already at his station, so go check there...." I said back, seeing Undyne and Alphys look at each other, then looking at you.

"Aren't you going to ask why we're together?" Alphys finally spoke up.

"I don't care, so I'm not going to ask, now leave, before I make you." I growled at them, glaring daggers at the two. Alphys took on a look of fear, but Undyne's expression stayed the same. "But sure, tell me why before you leave."

"Well me and Alphys are dating now, that's why, and she wanted to check up on (Y/N) after what happened." Undyne answered, leaving quickly after.

~~~~(Y/N)'s POV~~~~

You woke up in Sans' bed, so you decided to walk out to make some breakfast. Noticing you had Sans' jacket you put it on, and it was surprisingly comfortable. You walked out of the room and saw Sans spin around but relaxed when he noticed it was just you.

"Sorry about waking you up, I didn't mean to..." Sans said, sounding a bit guilty, but when he noticed that you had his jacket on, his face was quickly engulfed in red. He hugged you, not too long after he whispered, "Ya know, you look cute in my jacket, I might even let you keep it~" He kissed you softly and sweetly, and patted your head once he pulled back.

"Sans, I'm going to make breakfast, what would you like to eat?" You asked him, and you were wondering what Sans' favorite morning food was. (And I know a lot of people would see UF!Sans saying something dirty, but no, he knows reader is an innocent cinnamon roll~)

"I'll have a bagel, two bagels." Sans says as he puts up a peace sign to emphasize 'two'. (If anyone knows where that's from, you're awesome.) Your eyes legit sparkled.

"You love bagels too?" You say almost dying of happiness. Sans playfully scoffed. "Who doesn't love bagels?" Sans said as he rolled his pinpricks. You hugged him, full of energy. Sans hugged back and chuckled at how childish you were acting.

You run downstairs and get bagels, but you didn't know what type of bagels Sans liked but you wanted him to try the style you like. You make the bagels and hand a toasted cinnamon raisin bagel with strawberry cream cheese topping to Sans and waited for his reaction. But you walked into your room to see Frisk talking to Flowey.

*Google morning, Frisk, how did you sleep?* You signed to Frisk and they immediately responded *I slept great, thank you! How did you sleep (Y/N)?* Sans was watching the conversation, as if he knew what you were signing.

* I slept wonderfully Frisk, and here, I brought you something to eat.* You handed Frisk one of your specially made bagels and Frisk devoured it in seconds as you handed half a bagel to Flowey. He nodded and said a quiet thanks and ate it almost as quickly as Frisk did.

"Wow, your bagels seem to be gourmet deluxe by what I'm seeing, now is it truly as good as I'm being told?" Frisk nodded quickly and so did Flowey, trying to get Sans to eat it. Sans took a bite and he look surprised, glancing from you to the bagel and repeated the process until he finished eating the bite.

"How can a bagel taste so good?!" Sans was mesmerized, you brofisted Frisk and almost instantly you were pulled into a hug by Sans, who was twirling a strand of you hand around his finger and kissed you. " How can you be so unpredictable yet perfect (Y/N)?"
