Soriel 30 Day OTP Challenge (Oneshots Collection)

Day Six: New to the Family

prompt: " Each member of your OTP meeting the other's family for the first time. Does each family approve of the one dating the other? What sorts of shenanigans do they get into?"

"So...finally meeting the family, huh? Seems like things are getting pretty serious between you guys, am I right?"

"...Kid." Sans couldn't help but be amused, if a little puzzled, by Frisk's 'so what exactly are your intentions with my mother' routine as they smirked across the sofa at him. "We've known each other for how long now? Unless I'm missing something here, I feel like maybe that ship's sailed."

"I'm not talking about me." They were definitely up to something, a worryingly familiar determined glint in their eye as they turned to Toriel, tugging on her sleeve as she sat with her hands folded in her lap. "There's someone else we thought should join us for a nice family dinner tonight. Right, Mom?"

"Ah...in a sense, I suppose, yes." Toriel seemed much more reluctant, only offering Sans an apologetic smile when he looked to her for an explanation. "Dear, are you quite sure this is a good idea? He does tend to be rather...how should I put this..."

"Mom, don't worry," Frisk assured her, patting her hand. "I feel like we've been making real progress on the whole, um...attitude problem. Anyway, he's got to find out about you guys sometime, right?"

"I suppose, but..."

"We'll be right down!"

Frisk scurried eagerly off upstairs before she could object any further, and Toriel sighed before turning back to Sans, placing a hand gently on his patella. "Sans, I...do apologise in advance for this evening. I did hope we might be able to enjoy a nice, peaceful dinner, but you know how Frisk can be..."

Well, that wasn't ominous at all, but he smiled back anyway to reassure her, linking their fingers together. "Tori, don't sweat it. How bad can it really –"

"Hey, watch the stem!" A disturbingly familiar squeaky voice pierced the air, interrupting him as they both turned towards the stairs. "Why are we doing this? You know I don't actually need to eat – there's this thing called photosynthesis? That's pretty basic science, Frisk – golly, don't they teach you anything in school? Your mom must be so..."

The contents of the offending flower pot wisely fell silent as he met Toriel's steely gaze, a stark contrast with Frisk's determinedly cheerful smile as they reached the bottom of the stairs and placed the pot carefully on the coffee table.

"Sans, Flowey – you guys, um, remember each other, don't you?"

"How could I forget?" Sans gritted his teeth, hoping his resting smile masked his instinctive unease as he met the flower's belligerently unimpressed stare – he could still feel the vines tightening around him, scratchy and suffocating, remember looking over at Papyrus, at everyone helplessly ensnared around him and only thinking, as the energy drained out of his soul, that he'd seriously screwed up this time..."Hey, buddy. Steal any good souls lately?"

Flowey ignored him entirely, turning his head indignantly back towards Frisk. "Is this some 'cruel and unusual punishment' kinda thing? 'Cause if so, I'm actually..." His eyes widened to comical proportions as the proverbial penny dropped, darting from Frisk to Sans to Toriel and back again. "Wait, is this a – no. No way. You're dating him?!" He dissolved into hysterical, high-pitched giggles, doubling over at the stem. "That's too rich! M – Toriel, I know you're getting a little over the hill, but gosh – even you must be able to find someone better than some...bag of bones?"
