Sans squawked when he noticed that Papyrus was taking them back to their place. He planned to tell Gaster first.
Having his dad know about his relation to Frisk? Sure, no problem. Dealing with the teasing about 'early parenthood'? That could wait.
"H-hey, Tori...um..." Sans tried to look for a distraction. He just needed five minutes to mentally prepare himself.
"What is it, Sans?" Toriel asked, noticing Sans' expression and becoming worried.
"Uh...hey, Papyrus?" Sans called out to his brother.
"Yes, Sans?" Papyrus stopped jumping around with Frisk and looked at Sans.
"How about you show Frisk your puzzles around town first? There's some things we need to organize before we tell everyone" Sans was proud of his excuse.
"ALRIGHT! COME, HUMAN! I'LL SHOW YOU SOME OF MY BEST PUZZLES!" Papyrus told Frisk enthusiastically. Frisk seemed excited at the thought too.
"What's wrong?" Toriel asked when both Frisk and Papyrus were out of sight, leaving them alone.
Sans didn't answer. Instead, he fell forwards and went face first into the snow.
"SANS!" Toriel shrieked, worried.
"Sorry Tori" Sans sighed.
"Are you alright?" Toriel questioned.
"Yeah, I'm fine" Sans smiled.
"Are you sure?" Toriel hesitated.
"Calm down" Sans chuckled, not moving from his position in the snow, "I just need to prepare myself for pop's reaction to Frisk."
"Would he be mad at you?"
"No, if anything he'd be happy" Sans laughed, "he thought my personality was so lazy that he didn't expect me to get a girlfriend let alone a wife, and that he'd have to wait for Papyrus to mature before getting grandkids -not that I expect Papyrus to ever have kids-."
"What do you mean? Do you think that Papyrus wouldn't want any?" Toriel thought Papyrus would be the type to jump at the chance of being a father.
"Nope. I actually think he'd be more excited than his partner if it were possible. But it's not" Sans chuckled and smirked a little, "have you seen the way my little brother and Mettaton look at each other?"
"Papyrus and Mettaton?" Toriel blinked in surprise, "oh my, that's something I hadn't expected."
"Really? I thought it was obvious" Sans grinned, "fingers crossed they get together soon, I don't want to have to have a sexually frustrated Papyrus around for longer than necessary."
"Sans!" Toriel scolded, though it didn't have the effect that she wanted thanks to her giggling.
"They're going tibia interesting couple" Sans grinned wider at the pun oportunity.
"Are you sure you wont have a bone to pick with Mettaton when he steals your brother away?" Toriel giggled.
"Nah, that's Pap's job" Sans smirked. Toriel snorted at the slightly dirty joke.
"Alright, mr funny bone" Toriel smiled once they'd calmed down a little, "you ready?"
"Nope" Sans shook his head, rolling over and grinning as he held up his hand, signaling he 'needed' help up.
Toriel rolled her eyes and helped him up, "so where will your brother be?"
"This way" Sans said, looking in no particular direction as he grabbed her hand and teleported them.
