The Human Underground book one: Magic knows no bounds

Chapter 15

Alisa fixed Frisk's jacket as they got ready for their adventure through Waterfall. The older of the two had never actually gone to the place, hearing about the head of the royal guard not being much of a human lover. She had gone to hotland with Alphys though, taking a ride from the river person. It was slightly scary to be visiting the place for the first time.

"Got everything Frisk? I'm leaving the soul here just in case and I'll come after it while your traveling through Hotland. Tonight you will be staying with Alphys and I'll ask her to make a new container for it so you can carry it safely okay?" She explained to her adoptive sister, earning a nod.

Sans stood by the door, watching the two. He didn't have to touch Alisa nearly as much today because of them touching so much yesterday and also because of them cuddling all night. Though, he would still be watching them as they went through waterfall.

He also had been reading Alisa's magic book a lot lately, the girl finally letting him. He had read up a lot about their current mate situation and found out if one got hurt, the other would instantly know and, if the wound is serious enough, they will also go through the pain on a minor level. They could also find each other anywhere, no other magic able to block it. However, most of the stuff they could do as mates they couldn't do yet. They hadn't done the actually 'mating' part yet nor would they for a while.

"Ready! Sans? You okay there?" Sans snapped out of his thoughts to look at Alisa, who was looking at him concerned.

"I'm fine. Just thinking." He answered and she giggled slightly.

"With what brain you bone head?" She joked and he grinned at her. Frisk rolled her eyes and grabbed her sister's hand before pulling her away.

"No more flirting you two. You did that enough yesterday." The child commented. They laughed as she pulled Alisa away. Determination could take you a long way.

The two human girls walked through Waterfall in silence. Not that they were mad at each other or anything. They just liked listening to the sounds of waterfall as they walked through.

"Hey! Alisa! Dude, are you here to see Undyne too?!" They hear a voice and look ahead to see Monster Kid, who's nickname was MK.

"MK? What are you doing here?! You know your parents don't like you coming here alone!" Alisa exclaimed as she went up to the kid. MK shook her head.

"Don't tell them please! I just wanna see Undyne!" MK exclaimed and the girl sighed before rubbing her temples.

"Man, I don't want to deal with this. Fine MK you can stay and see Undyne but you have to be careful. Undyne doesn't like humans and I've never met her, or am I very inclined to meeting her. You have to listen to what you are told okay?" She explained and the kid nodded.

"Alright dude! Heya Frisk! You're here too?!" MK exclaimed, walking over to Frisk, now noticing her. Alisa face palmed and heard a laugh from a certain skeleton.

"Sans, shut it." She said out loud, earning another laugh as the short skeleton teleported in front of her and helped her up.

"I just wanted to let you know that Undyne is in the room ahead. Me and Paps have to meet up with her but there's some bushes below that you can wait in until she passes. Be careful okay?" He tells her as he helps his mate up. Alisa nods before kissing his cheek.

"Thanks for letting me know Sansy." She said and a blush appeared on his skull.

"No problem Babe. See you in a bit." He tells her before teleporting off again. Alisa smiled before grabbing her two charges as they start going through the caves again.

"Shit shit shit shit shit shit shit shit shit shit shit shit SHIT!" Alisa repeated as she picked up Frisk and ran from the spears. MK had disappeared earlier, going another way after running ahead. Undyne had seen them however and was now throwing spears at them.

"Sis! Watch out!" Frisk yelled as Alisa rolled them out of the way of another set of spears as they finally got out of the room. She sighed in relief as she put the girl down, then plopping on the floor with a tired sigh. Frisk looked at Alisa worryingly.

"You okay Sis?" She asked and Alisa nodded.

"Fine, just tired and slightly out of shape. I haven't really trained much since you appeared you know?" She told the child before getting up and stretching her arms, hearing her bones pop slightly.

"Wow babe. Even your bones sound tired." Sans joked as he appeared. Alisa looked at him and frowned.

"You could've teleported us out of there Sansy. I can't exactly use magic while Undyne's around and I can't copy your teleporting powers anyways." She told the skeleton, who shrugged.

"I'm technically suppose to capture you two so I'd probably get in trouble if I did. I don't really need to get yelled at yet." He answered with a lazy grin. Alisa rolled her eyes before grabbing Frisk's hand.

"Well then, Mr. smartypants. We'll see you when we get to Hotland." She told him before marching off. His grin faltered a little. She was obviously a little angry with him and he didn't like the feeling, AT ALL. Guess he better change that.

"Sorry Babe. Please don't be mad at me." He said as he follows behind them. Frisk watched her adoptive sister try to keep frowning. She didn't want to stay mad at her mate.

"Too late. Already am." She answered and he frown before grabbing her hand.

"Then stop being mad. I am sorry okay? I love you a skeleTON." He told her as she smiled slightly before squeezing his hand.

"Love you too. I can't stay mad at you for something as stupid as that either. Next time though, stay out of sight and redirect some of those spears please?" She asked and he grinned and nodded, entwining his fingers with hers.

Frisk smiled as she walked with the two. She loved how cute of a couple the two were. She actually couldn't wait until they got married and was determined to see that happen sometime soon after the barrier was broken. She finally had a family, with a mother in the ruins, and a sister and two brothers in Snowdin, the girl felt like she belonged. She couldn't wait to see what other family members she might get through the rest of the journey and couldn't be happier.
