The Fallen Angel - Underfell

Mine

"Sans!"
Sans kept smacking the guards against the wall. After a few smacks he stopped and calmed down.
The glowing eye faded out.
"Are you alright doll?"
"Y-yea I am."
"Are you sure?" Sans brushed Frisks hair out of the way so he could see her face, he could see tears in her eyes.
He pulled her close to him and hugged her. Frisk hesitated.
"What if Papyrus sees us?"
"He won't, he went to bed right after we got home, guess that 'trap' was really tiresome."
Grillby returned back to the bar with Frisks order prepared.
"What was all that noise?" He saw Sans hugging Frisk tightly.
"Sans?"
Suddenly in a blink of an eye Sans grabbed Grillby by his shirt and nearly dragged him over to counter.
"YOU MOTHERFUCKER I THOUGHT YOU'D LOOK AFTER HER WHEN I WASN'T AROUND!"
"Sans calm down,please."
Grillby was shocked, he had never seen Sans like this before.
"Sans, please stop." Frisk cried out.
Sans turned around and his expression softened when he saw Frisk bursting into tears.
He let go of Grillby, grabbed Frisks hand and teleported away.

The environment was calm and soothing, they were at Waterfall now. They were sitting by the river.
Sans let out a deep sight.
"I'm sorry....I didn't know what happened to me...when I saw those guards...." Sans paused and clenched his fist. He inhaled and exhaled. "Touch you like that....something snapped, I...couldn't control myself."
Frisk grabbed Sans' hand.
"It's okay Sans, you saved me, that's all that matters."
Sans looked at her, she was so pretty. He could stare at her for ages.
Suddenly she waved her hand in front of his eye sockets.
"Hey bone head are you still with me?" She laughed.
"Sorry I got lost in your eyes." Sans said shyly.
"You know, it's pretty funny to see you all shy and flustered.
The Sans from my universe never was like that, he always knew what to say, and was never embarrassed."
"Doll...can I ask you something?"
"Sure, ask away."
"Did...you had feelings for that other me?"
"Well, not really, I mean he was a great friend but..."
"But?"
"It often felt like was putting up an act, as if he pretended to be such a joker. He...barely opened up to anyone actually. As if he was blocking us out. I tried to break through his shell...but without any progress." Frisk looked sad.

"Am I...different than him?"
"Sure, look way more edgy than him." Frisk said giggling.
Sans tackled her on the floor and was lying on top of her.
Frisk eyes widened, her face was getting all flushed red, she didn't expected this at all.
"Sans?"
Sans smirked.
Sans pressed his teeth against her lips. Even though Frisk was confused she closed her eyes and kissed him back.
Then Sans broke the kiss and sat back up.
Frisk slowly sat back up as well.
"Sans? Why did you-?
"Because I want you to know that I'm me...and not him..."
"Sans...I know."
Sans held his head.
"I'm...really sorry...I just don't know what's wrong with me today..."
"I think...that's called being jealous."
"I just feel as if I want to make sure that you're..."
"That I'm what?"
"Mine....and mine alone..."
"Ofcourse I am, why do you think I'm not?"
"I don't know....but whenever you're talking about that other me...it felt as if you had feelings for him."
Frisk looked down.
"Well...I used to...but after I figured out he wouldn't ever open up to me...I gave up."
"Frisk..."
Frisk was surprised to hear him say her name for the very first time.
"You're not....projecting those feelings on me right?"
Frisk shook her head.
"No, I know you're different than him...You're not afraid to show your emotions, you don't shut me out."
Sans smiled.
"I've never loved someone before you know..."
Frisk looked up at him and kissed him on his cheekbone.
They stayed there for a while until Sans realised something.
"Doll, have you eaten today yet?"
"I only had breakfast today, I was going to have dinner at Grillby's but didn't turn out too well as you know.
Sans stoot up.
"Wait here, I'll be back in a second."

He teleported away and returned with two hamburgers.
"You can have both if you're really hungry."
Frisk mouth started to water when seeing the burgers, she really felt hungry. She quickly ate both. When she was finished Sans handed her a napkin.
"You got some ketchup on your chin."
"Oh, but why would I need a napkin if I got you?" Frisk teased.
Sans was speechless, he didn't know what to do or to say.
Frisk laughed she thought he was adorable when he was all shy like that. But when she tried to take the napkin Sans stopped her, cupped her chin and let his tongue slither to her chin, lapping the ketchup up.
Sans tongue felt weird, it was glowing bright red, and felt slimy.
Then Sans pushed his luck even further and entered her mouth.
His tongue rubbing against hers.
Neither or both had ever done something like this so the kiss was pretty sloppy.
When they broke the kiss both were panting and blushing madly.
Sans scratched the back of his skull...."I think we should go home now...it's pretty late."
Frisk wasn't feeling tired but agreed anyway.
It was clear both were pretty embarrassed.
Sans dropped Frisk off at the hotel, hugged her one last time and teleported back to his room when Frisk went to hers.
Both kept thinking about the events which happened today and eventually fell asleep happily.
