Under Infusion Tale- (An Undertale Fanfiction Novel)

Chapter 20: Somebody Finally Came

Husband? He really called Sans, husband. They never did that unless they were ACTing.

As Papyrus left, Sans continued. "I know this marriage thing feels weird, 'cause we've been friends. It's only gonna get weirder, Moonkose. We are going to be doing things each day, to determine where your spot is."

"My spot?" Frisk asked.

"Uh, yeah?" Sans nodded. "I've been close enough to rule out some already. You're not daughter or even sister. So, you could be neutral. That means you actually went with Papyrus' energy in some way, but since I'm related to him, that connection is still there. Usually bonds as close friends."

"Okay," Frisk said slowly. "Instinct drove to me to Papyrus, but because you're his brother, it was close enough?"

"Yeah, that's one," Sans said. "Or, you could be my lover and the one I truly love above all others or some poetic shit like that. Or umm? I could have absolutely no lovey-dovey feelings and it's just all out hot passion brewing between us at like all hours. That's called a Luster. It can be a combination too." He put his feet up on the coffee table. "Evolution will know."

"But we're just friends," Frisk said. "It either has to be sister or neutral."

"Nuh uh," Sans said with certainty. "Just 'cause you pair with my brother's instinct as sister, doesn't make me your brother. It's not a blood thing, it doesn't work like that. It's a monster energy thing. Family doesn't find its way that way. Hell. Heh heh heh heh. You could be 'mom' to me."

"Uh?" Frisk blinked. "That's possible? I'm much younger than you."

"Don't worry, you aren't mom either," Sans told her. "I've felt you out enough, I know you aren't that."

"Well." Frisk shrugged. "We're friends then. Neutral."

"Never know," Sans insisted. "We could be friends, but at the same time, you could be more drawn to getting my energy inside of you than keeping a friendship. Everyone lies to themselves all the time, especially monsters who really wanted a wife. Someone to hold every night, emotionally or physically."

But? "We can't be anything but friends," Frisk said.

"Well, aren't you so sure of yourself," Sans said. "Miss Frisk don't like dem bones. How do you know that? I ain't even seriously taken you out."

"Because you don't like guys or girls sexually," Frisk said. "Right?" This conversation was getting weird. "I don't know how it works."

"Uhhh?" Sans put his feet back down. "Could you come back on that a second again? What do you mean I don't like guys or girls?"

"Oh. Alphys and Undyne told me when we first accidentally got married," Frisk said.

" . . . say whaaaa?" Sans stood up from the couch. "Nah, nah, I'm all about girls! Not that being a lone monster is bad or nuttin', but that's not me and, I'm always thinking about girls!" He looked toward Frisk. "I mean, not about you. Well, maybe. But nah, I'm not like that." He pushed his hands toward Frisk. "Well? I'm not like that either. You know? I'm not always thinking about you sexually. If I do. It's all infusion confusion!"

"Oh?" Oh no! "Oh, I'm sorry! They just told me so many times that I needed to be careful. I didn't want you to ignore me like you did Toriel," Frisk confessed. "I'm sorry, Sans."

"Toriel was the one who told them?" Sans asked. "How long ago?"

"I don't know?" Frisk shrugged. "I think many years ago."

"You were always ignoring her," Papyrus said to Sans as he came back in, interrupting them. "She had to make her own assumption at some point."
