Are Souls Supposed to Do That?

News spread quickly about what had happened to Canis and his small gang of monsters that wanted to be tougher than they really were. Sans was probably a little too happy at the looks of fear he'd gotten the last few days just wandering around with Frisk and getting her accustomed to being back in public with him.

Boss had had a hand in that. He'd made it clear to everyone that, as far as he was concerned, she was a monster like everyone else. Anyone who had a problem with that had a problem with Boss, and nobody wanted to have a problem with Boss.

Frisk decided that she had to get to know Boss better. She begged Sans for days, never relenting until he finally allowed her to invite his brother over for dinner.

Boss had been surprised to say the least, but he accepted the invitation. When he found out they were planning to order from Grillby's because Sans couldn't cook for shit and Frisk didn't know how to make monster food, Boss decided he was going to have them over at his place instead. Sans made him promise he'd make something a human could ingest. Eyeball spaghetti was not that, he said. Boss was a little dejected but decided he could simply omit the eyeballs and call it good.

Frisk smiled brightly up at Sans as she put her shoes on. He smirked at her; for some reason she was excited about dinner at his brother's.

"You're making this into a bigger deal than it is, sweetheart," he insisted.

She giggled and skipped up to him to take his hand. "Actually, I think you're not making a big enough deal about this. When was the last time you and your brother had dinner together?"

He thought about that for a second. "Probably before Mom died."

Her eyes widened. She had figured it had been a while, but she never thought it could have been that long. "Sans, this is really important, then. He's your brother; your family." She squeezed his hand. "Can we make this a more permanent thing? Like once a month?"

He smiled down at her and kissed her forehead. "Maybe."

With that, he wrapped his arm around her and teleported to Boss' place. He knocked on the door and shifted uncomfortably. He wasn't sure what to expect out of the night, even if he knew Boss wasn't likely to make anything awkward.

The door opened, and Boss stepped back to let his guests in. He nodded at Sans and managed a smile at Frisk.

Frisk was having none of that. She knew, based on what Sans had told her about how he'd helped rescue her, that Boss wasn't as heartless as he liked to pretend. She stepped forward and up on her toes to wrap him in a hug.

Boss stood rigid and looked at Sans with wide sockets. He didn't know what to do. Would Sans get mad if he hugged her back? Would he get mad if he didn't hug her back?

Sans snickered at the look on his brother's face. He shrugged to let him know he didn't care what he did. Frisk made her own decisions and damn what anyone else said about them.

Boss chose to gently pat her back for a moment before she pulled back.

"Something smells good," she said as she stepped back to Sans' side and took his hand.

Boss smiled again. "THANK YOU. YOU'RE RIGHT ON TIME; DINNER IS READY." He led the way to the dining room where three places had been set up.

Sans pulled Frisk's chair out for her. She smiled up at him as she sat down. He winked at her as he took his seat next to her. He took her hand and smirked at the blush that had crept across her cheeks.

Boss came in and set a serving dish in the middle of the table. He took his seat and gestured for his guests to go first.

Frisk stared at the dish, not entirely sure what it was she was about to eat. Something about it resembled spaghetti, but she was pretty certain the noodles weren't supposed to move on their own.

Sans coughed. "Um, Boss?"

"WHAT?"

"I said something a human could ingest. You really think she's gonna be able to eat that?"

Boss scowled. "WHY? WHAT'S WRONG WITH IT?"

Frisk cleared her throat. "I guess I'm just not used to eating things that are still moving. What is it made of?" If he said worms, she would puke right there at the table.

"I think it's better if you don't know," Sans said, meeting her eyes. "It ain't bugs, if that's what you're worried about."

Sans found himself actually eager to eat. He hadn't had this dish in fucking years, and it used to be his favorite. He'd never learned how to cook it, preferring to spend his energy on other things. He reached out and put a small portion on Frisk's plate before giving himself a large helping.

"If you can't eat it, don't worry. Are you okay?" He had to smile at the look on her face. She was turning a little green.

"It's not worms, is it?"

Boss scoffed. "I WOULD NEVER SERVE FUCKING WORMS."

She raised her eyebrows. "Okay, sorry." She picked up her fork and stabbed a wriggling noodle. "It's not anything from a human?"

Sans chuckled. "I wouldn't let you eat it if it was."

She nodded, took a breath, and shoved the fork into her mouth. Surprisingly, it wasn't terrible. She managed to chew despite the strange sensation of her food moving in her mouth. The flavor reminded her of the spaghetti she'd had in her world. She swallowed and decided she'd put up with it. This was a special occasion, after all.

"OH, I ALMOST FORGOT." Boss got up and went back into the kitchen. He came out with three glasses and a tall bottle.

Sans laughed. "You planning to get us drunk?"

"I KNOW YOU NEVER CARED FOR HOSPITALITY, SANS, BUT THAT DOESN'T MEAN I CAN'T BE A GOOD HOST." He set the glasses down and filled each of them from the bottle.

"Go easy on that," Sans said as he picked up his glass. "You ain't used to that shit." He downed his glass and hissed before setting it back down. "Boss, how much'a that you got?"

Boss huffed a laugh and shook his head. "PLENTY."

All three sat in Boss' living room laughing as Sans told Frisk about their childhood.

"So Paps goes into the kitchen to get the fuckin' cookies and finds an empty plate." He laughed so hard he was wheezing.

Frisk couldn't help but giggle at the red that stained his cheekbones. The story itself wasn't that funny but watching Sans as he recalled the memory was.

"YOU FUCKING TOOK THEM ALL, YOU BASTARD!" Boss hollered.

"'Course I did; what's a big brother s'posed to do?"

"OH, I DON'T KNOW, NOT BLAME THAT SHIT ON ME!"

Sans burst out in laughter again, his arm around Frisk shaking as he attempted to breathe.

Dinner had been nice, and they were all nicely drunk after finishing two bottles of Grillby's special vodka.

"So what happened?" Frisk asked. "Did your mom get mad?"

"Oh, she was fuckin' pissed. Dad was worse, though. Luckily for Paps, he saw right through my shit."

Boss scowled and crossed his arms. "IT TOOK THREE MONTHS FOR YOUR ARM TO HEAL AFTER THAT."

Frisk furrowed her brow. Sans pulled up the sleeve of his left arm and showed her jagged scars through both his radius and ulna. She lightly touched them. She'd noticed them before, along with other scars on his bones, but never thought to ask about them. She had just figured it was a result of growing up in such a violent world.

"He broke your arm?" She looked up to meet his fuzzy eyelights. They seemed bigger than normal and blurred around the edges. She was pretty sure her eyes looked a bit glazed over as well.

"I got off easy. Like I said before, he wasn't a good dad." He pushed his sleeve back down and hugged her to him. He liked feeling her soft body next to him like this.

After she broke down and confessed that she felt guilty for what had happened to her, they both worked on keeping communication between them as open as possible. She was still hesitant in bed, and he was still patient with her. He would wait forever for her, as long as she never shut him out again.

Frisk snuggled into his side and turned her attention back to Boss. "So, is that your real name then? Paps?" Boss' eye lights resembled Sans'; large and unfocused.

"NO. IT'S PAPYRUS, BUT SANS HAS GIVEN ME MANY DIFFERENT NICKNAMES."

"Papyrus. I like that." She hummed softly and smiled when she saw the orange blush on his cheeks darken just a little. "What other nicknames do you have?"

"He just means I've called him a bunch'a names. Shit like Paps, Pap, Paprika, Papaya…yeah, a lotta shit."

Frisk couldn't help but giggle. "Paprika?"

"HE'S JEALOUS BECAUSE I KNOW HOW TO USE THE SPICE AND HE DOESN'T."

Sans snorted. "Yeah, let's go with that, bro."

"So when did you start calling yourself Boss?" she asked, directing her attention back to Boss.

"THAT WAS ALSO SANS' IDEA. IT WAS AFTER I STARTED TAKING OVER SOME OF THE PROBLEM AREAS AROUND TOWN. MONSTERS AROUND HERE NEVER LIKED TO BE TOLD WHAT TO DO, BUT EVERYONE DOING WHAT THEY WANT ISN'T ALWAYS IN THEIR BEST INTEREST. WITH MY MAGIC LEVELS, I COULD EASILY VANQUISH ENEMIES WHO STOOD IN MY WAY."

"Did Sans help you?"

"Like I wanted any part of that shit. I ain't a leader, Frisk. I'm too fuckin' lazy for that shit."

She scowled at him; she didn't think he was lazy, and she thought he'd make a great leader. At least, as he was now. Perhaps not in the past.

"SANS DID MORE THAN HE KNOWS. MONSTERS WEREN'T AFRAID OF ME, BUT THEY WERE OF HIM. I'D THREATEN TO GET MY BIG BROTHER INVOLVED, AND IT USUALLY STOPPED ANY ARGUMENTS UNTIL I HAD ENOUGH CONTROL OVER MY MAGIC TO HANDLE MYSELF."

"When did Sans start working for you?"

Sans arm tightened around her, and she looked up at him. He smiled and kissed her. She was too curious for her own good. It didn't bother him, necessarily, but he was getting tired.

Boss looked at Sans for a moment. When Sans nodded, he continued. Frisk furrowed her brow and decided she'd have to ask about that later. Was he asking permission to tell her something?

"A FEW YEARS AFTER I'D ESTABLISHED MYSELF AS LEADER. APPARENTLY, NOBODY ELSE HAD THOUGHT TO ACTUALLY ASSERT THEMSELVES THE WAY I HAD. THAT WAS BOTH GOOD AND BAD, BECAUSE I DIDN'T HAVE COMPETITION UNTIL OTHERS DECIDED THEY'D BE BETTER AT IT THAT I AM. RIDICULOUS NOTION, OF COURSE. NOBODY COULD BE A BETTER BOSS THAN THE TERRIBLE PAPYRUS! NYEH HEH HEH."

Frisk couldn't help but snort at the laughter that just came from Boss. It was the most adorable thing she'd heard in a long time.

"Oh my god, that was cute!" she squealed, her inhibitions clearly gone.

Boss' jaw clamped shut and he crossed his arms over his chest again.

"IT'S NOT THAT FUCKING CUTE!" he all but yelled.

Sans chuckled. "It's adorable, Boss. Long story short, I helped him keep his throne, as it were, and I punished monsters that broke the rules."

"When did you start hurting humans?"

Boss apparently had no interest in answering that question, still butthurt over Frisk's reaction to his laughter.

"We should probably go home, Princess."

Frisk looked up at him. "But I still have questions."

"And I'll answer 'em later. C'mon."

He helped Frisk stand up and carefully got to his feet beside her. She stumbled over to Boss and leaned down to hug him again.

"Thank you so much for having us, Papyrus. I hope we can do this again soon."

Boss sighed and hugged her back. "PERHAPS."

Sans ended up having to peel her away from his brother. She protested, saying she didn't think he'd had enough hugs in his life and she intended to fix that. Boss was quick to tell her she'd have plenty of time for that later; they'd get together again.

Sans didn't dare teleport; he was too drunk for that and fuck only knew where they'd end up. He kept a protective arm around Frisk's shoulders as they walked home.

"I'm cold," Frisk said softly, snuggling into his side.

"You're always cold."

"No, but I'm really cold. Can I wear your jacket?"

He snorted. "No. You shoulda thought about that shit."

Even as he said it, he was pulling the zipper down. He shrugged out of it and draped it over her shoulders. She pushed her arms through the sleeves and zipped it up to her chin before snuggling back into his side.

"Thank you."

"Yeah. Now I'm cold."

She grinned up at him. "You shoulda thought about that shit." She knew he was teasing; he didn't get cold.

He chuckled and leaned down enough to kiss her. They both stumbled but managed to stay on their feet.

They maintained a comfortable silence after that. It seemed to Frisk that she got more and more tired with each step she took. Sans' arm around her was enough to keep her up, and she wasn't about to curl up on the ground any time soon.

Sans was aware of the monsters around them. He hoped none of them thought that him being drunk meant his reaction time or magic was impaired in any way. He'd had too many drunken nights to practice for that to be the case.

Luckily, nobody tried anything. He was still relieved when they finally made it home. As soon as they were inside, Frisk pulled away from him to go collapse diagonally on the bed. Sans shook his head to himself and went to pick her up.

"We gotta get you outta those clothes, Princess," he spoke into her ear.

Frisk sighed happily at the feel of his breath and the low sound of his voice. She didn't do anything to help but instead leaned back against him as he unzipped the jacket and pulled it off. A soft, relaxed sound escaped her throat when he started to unbutton her jeans. She felt hot in all the right places. She knew he wouldn't try anything; he was merely trying to get her comfortable. That fact was made even more clear when he gently slipped her jeans down her hips, making sure to leave her panties in place.

Sans' bones were heating up fast he pushed her jeans down. He wanted her madly. He loved the trust she had in him as he undressed her, but he felt like maybe it was a little misplaced. She was drunk, but so was he. He wanted to pretend he'd have the strength to resist her, so he continued what he was doing. He wasn't at all prepared when she hooked her thumbs in the waistline of her panties and started working them down, shimmying her hips so her ass moved against the front of his pants as she did so.

"Frisk—"

"Shh." She leaned against him further, using his strength to keep her balance as she kicked off her shoes. Her pants and underwear soon followed. She then turned in his embrace and gripped the front of his sweater in her fingers. "It's okay, Sans," she whispered, looking up into his face. "It's okay."

Sans swallowed thickly as she started to lift up on his shirt. He didn't help her, but he didn't stop her either. She pushed her hands under and started to gently brush her fingertips across his lower ribs.

"You're drunk," he finally managed. His hands found themselves on her hips and he pulled her in closer.

"So are you." She gave him a lopsided smile before ducking her head under his sweater to kiss his sternum. She let her tongue gently trace a scar there before she pressed her lips to another one.

He shivered and pushed her back enough for her come out of his shirt. Without a word, he lifted up on hers and dropped it to the floor beside them. He did the same with her bra. Before she let him push her down onto the bed, she made him take off his clothes.

He was torn as they laid down together. He wanted to fuck her into the mattress and make her scream his name, but at the same time he couldn't be sure she was actually ready for this. Something in his soul tugged hard with the question of if she'd regret it when she was sober again. He didn't fight her as she pushed him onto his back and continued kissing and licking his ribs. He couldn't. It felt too fucking good to push her away now.

Frisk was burning up in the best possible way as she explored his bones. She'd never taken the opportunity to explore him like this, and she made a mental note to do it more often. A part of her wondered if drunk her would end up tossing that note or if she'd somehow remember. His hands were on her back, gently rubbing in circles as his claws scraped softly. She didn't think she could ever get enough of this.

She scooted down a little when she reached the bottom of his ribs. She paid as much attention to him as she could, taking in his sudden intakes of breath and soft grunts as she continued her appraisal by moving to his spine. He sucked in a hiss and his hands moved to her shoulders. She wasn't sure, but she thought he may have pushed her gently. She took her time moving from one vertebra to the next, slowly making her way to his pelvis.

His erection was straining against her skin as she moved. Sans wanted nothing more than for her to suck him off right there; he'd never been so fucking turned on in all his life. Something about her taking charge tonight was the sexiest fucking thing in the world. His claws dug into her hair as she kissed and licked at the bones of his pelvis. She skipped right over his hard member. He whined and bucked his hips into her.

"Sans."

Her small voice caught his attention, and he looked down. Her face next to his dick was a sight to behold. He swallowed and grunted.

"I'm not going to suck your cock," she said flatly. "I can't. I'm sorry." She shook her head. "No, I'm not sorry." She knew he would understand.

He smirked and softly ran a claw down her cheek. "Not a problem, Princess." Yeah, he wanted it, but not that badly.

She gave him a few more kissed around his pelvis before working her way back up. She didn't take her time going back up; she had a goal to achieve this time.

Sans didn't expect anything else as she settled herself next to him and kissed his clavicle. He'd had a hell of a night already, and it wasn't like he wasn't used to jerking himself off anyway. He hugged her to his side and kissed her forehead. Before he could pull back, however, she pushed herself back up.

"I needed a minute," she said softly. She'd felt a rush of nausea as she contemplated straddling him and so took a moment to calm down next to him. She'd reassured herself that he wouldn't push her; this was Sans. She loved him with every ounce of her being, and she was tired of hiding behind fear. She was ready to be with him again.

He furrowed his brow as she positioned herself on top of him. He stopped her as she reached under herself to grip his dick.

"Frisk, wait." How he managed to have the self-control to stop now, he didn't know. "You really are drunk."

"Yes, I know. Sans, I want this. I really, really do. Please don't make me wait until I sober up, because then my brain will sabotage me again." She pulled her hand back and lifted her hips enough to position his dick. "Please?"

He didn't have nearly as much control as he wanted to have. He nodded and lightly gripped her hips as she eased herself down. They both moaned as he filled her. She settled herself on his hips, letting her body adjust to his size. It had been far too long, she thought. She licked her lips and leaned forward enough to brace her hands on his ribs. His hands moved up to her waist and held just tight enough to steady her as she rocked against him.

Their lovemaking was slow yet needy. Neither said a word, yet their sounds of pleasure filled the room. Her fingers gripped his ribs tightly as her movements against him became more rushed and less coordinated. Soon his hips were leaving the mattress as he thrust into her with each of her descents. Her back arched and her toes curled; she leaned down over him and squeezed her eyes shut tightly as she came undone.

Sans wasn't done yet. He flipped them over so he was on top. He kept their connection close, laying on top of her as he thrust into her. He kissed and nipped at her shoulder until he came, swearing into her skin.

Both were panting hard as he collapsed next to her. She curled up against his side and he wrapped both arms around her to hold her close. He didn't feel like he was close enough. He turned on his side to hold her better.

"I love you, Sans," Frisk whimpered. Her voice gave away that she was half asleep.

He kissed her and tightened his arms around her. "Love you, too."

He sucked in a deep breath and closed his eyes. It wasn't long before both of them were out cold.

A chill in the air caused Frisk to shiver as she slept. She nuzzled closer to Sans, wrapping her arms around his ribs. Their chests were pressed together. Sans grunted as a strange warmth invaded his chest. It wasn't enough to wake him. It spread from him to Frisk. She began to snore softly, her brows furrowing as something tugged in her chest. Had she been awake, it would have reminded her of when Sans showed her how souls mated.

Sans' chest began to glow, softly casting red light around the room. A small tendril of red light pushed its way past his sternum. In response, a matching red tendril came from between Frisk's breasts. They met in the near nonexistent space between their chests, swirling together and becoming one to form a ball of light. The color drained until it shone a brilliant white and slowly took the shape of a tiny upside-down heart. The new soul sank into Frisk's chest. Under her skin, a bright glow could be seen making its way slowly down her body to settle in her womb. It dimmed until it no longer showed outside of her body.

The light in Sans' chest disappeared, leaving the room dark again.
