His hand hadn't yet moved to open the door. What's he waiting for? Frisk wondered. If they stood out here hesitating for much longer, they'd get cold feet - figuratively cold feet, because standing out in the snow had made them pretty cold already - and go home. Was he nervous? ...She certainly was. But beyond the nerves was a thrilled feeling; a longing to step into the unknown and do something that could be considered a little crazy.

"Sans? Are we...are we going to do this?"

Frisk heard him swallow dryly. "You sure about this, Frisk? You're not just... saying you do because I asked you?"

She bit her lip. "Well, I gotta admit that I haven't really ever given it much thought before you brought it up, but now that you have...I like the idea. I'm saying yes because I want to. Promise."

"Okayyy…" he exhaled. Not sounding so sure anymore, Sans at last pulled the door open. A warm whoosh of air hit them, along with the comforting smell of fried food and counter cleaner. Like Effervescence, it was dimly lit in here, but that was because the owner of the place casted all of the light that the place needed. Said owner was in his usual spot, dusting off the polished oak of the bar in front of him. There was not a customer in sight.

He looked up when Sans and Frisk entered, his flames letting out small crackles as he recognized them. "Hello, you two," Grillby greeted them softly. Almost everything he said was uttered in a very quiet voice. Frisk didn't think she'd ever heard him speak above a murmur. She wasn't even quite sure he had a mouth. Still, that didn't make him the most unusual monster in the Underground.

Many monsters had strange appearances, but not Grillby. There was only one way he could be described; hot. He was tall, lean, always flawlessly dressed. Would she even recognize the man in casual clothing? Perhaps not.

Though he simply ran a bar and restaurant in a snowy little town, Grillby took great pride in his work. The floors and tables were always clean, the food always cooked to perfection, and the needs of the customers were always instantly accommodated. It might not have been the snazziest eatery down here, but Frisk adored this place. She adored this man that she had been around for so many years.

And yet...she knew so little about him. How old was he, for example? How long had he and Sans been friends? Most urgently, would she go up in flames if she touched him?

Frisk supposed that they would find out in a minute or two.

"What brings you here? And looking so dapper." She could swear Grillby's tone held a small smile. He had a strange way of speaking; while he shared the same language as most monsters in the Underground, his accent was different. He said some phrases that Frisk didn't quite get, little things like tellings Sans he'd gone barmy if he'd had too much to drink or using bloody as an expletive - it was part of his charm, she supposed.

"We were just in the neighborhood," Sans explained, trying to sound casual and not quite pulling it off.

"Unusual," Grillby quipped, not taking his eyes off of his work. "Seeing as you so rarely come in. Why are you really here, Sans?"

Frisk swore Sans ducked his head like a scolded schoolgirl. Later, Sans told her that one of the unnerving things about Grillby he'd noticed during their brief relationship was that you just couldn't hide anything from him. He had an uncanny habit of getting it out of you no matter how badly you wanted to lock it away. Grillby, with his stoic demeanor and to-the-point way of speaking, was an expert at extracting information.

"Aw, jeez. You don't miss a thing, do ya?" Amused, she watched her boyfriend flush in this flame's presence. It wasn't hard to tell who'd been the top in this past relationship. "Frisk here, me and her...well. We came to see if we could... pay my tab."

Grillby pondered this, pausing in his polishing for the first time. "I don't recall this young lady ever owing me money." He dipped his flaming head to her politely. "You, on the other hand, Sans...shall be indebted to me for quite a while."

Realization hit Frisk; Grillby knew exactly what Sans was asking. He'd picked up on it the second he saw them. They were just being toyed with now. His tone had made it obvious to her at that moment. That's...kind of sexy.

"Just say it, Sans." Grillby had completely stopped what he was doing, and was now leaning forward with both elbows to peer at them over the bar. "I know what the two of you have really come for; it's written all over your faces. Just confess, and maybe I'll be nice."

Sans and Frisk shared a sideways look. This was sure going to be something, wasn't it? Frisk's newly strengthened heart was pounding under the look Grillby was giving them. Like they were prey he'd been hungering for, and now they were just where he wanted them to be. She'd never had the opportunity to see him like this, and she was thinking that accepting Sans' idea to come here and do this was a better idea with every passing second.

"We want to fuck you, Grillby. Both of us."

Frisk couldn't believe she'd just said that. Neither could Sans - she'd never seen him give her a more shocked (and perhaps even awed?) expression. Even Grillby's eyebrows seemed to be raised. And then, the most extraordinary thing happened. He grinned at her.

After never once seeing his mouth, or even knowing if he had one, Grillby fixed her with the most lecherous gaze she could have imagined. His mouth, now that she could see it, was a little alarming; a molten orange line tucked far under his glasses - where a human's mouth would probably be - a grin as wide as the Cheshire Cat's and twice as sharp with fiery teeth. No wonder he only mumbled.

"That's all that I needed to hear, darling."

Darling. The word slithered from his tongue as soft and smooth as snakeskin, and Frisk shivered. She had a feeling that Grillby was not the same man in bed as he was when he was running the restaurant. He was the type of person whose personality split the moment he got you flat on your back.

Calmly, Grillby placed the rag he'd been cleaning with under the counter and strode to the front of the restaurant. With one simple motion, the Open! sign was flipped, the door locked. If Frisk's heart was pounding before, it was nothing compared to the thrill she felt now. Sans was in much the same state beside her, watching Grillby's every move.

"My flat is through this door. Come." Grillby demanded, not stopping to see if they would follow. He was confident that they'd be on his heels. "Well...hopefully you'll also do that later." Frisk heard him chuckle as he pushed through the door that separated the kitchen from the bar. She'd never been back here, but it too was kept just as clean as the floor. To their immediate right was a narrow stairwell, leading no doubt to Grillby's living quarters.

Managing the steep steps was a little tricky in her dress, but Frisk managed. Grillby, ahead of her, had already unlocked his door and was waiting for them to step in. The interior was rather what she would have expected from Grillby; very tidy, maybe a little sparse. The living room was small, and had a kitchen off to one end. To the left of that was what Frisk assumed had to be the bedroom, as that was directly where they were being led.

Once the party of three had been herded to the bedroom, the door was promptly shut behind them. So this was where Sans and Grillby had had all of their sex. The bed was...massive. Frisk imagined that Grillby had some sort of enchantment cast on this place, so that his fire didn't cause anything to go ablaze. How far did the enchantment extend? The floor, the sheets, the mattress? It must be difficult to be made of fire.

"You'll want to shed those nice clothes," Grillby warned them. "They won't last long if I'm fucking you in them."

Turning to Sans, Frisk grabbed him by the front of his shirt and kissed him. Surprised, he gasped against her mouth. She spared no thought for gentleness; this kiss was a violent one. After seconds, she heard him moan, letting his tongue form so that he could better reciprocate. In the meantime, Frisk had undone his pants, the suspenders had come down, the bowtie (clip-on) had been done away with - now she was deftly working on the buttons of his dress shirt.

Still expertly letting her tongue work against Sans', Frisk opened one eye to see Grillby's expression. Was he enjoying this little performance? This was her revenge for being teased earlier, and judging from the look on his normally passive face, it was rather effective. His fiery body had flushed a deep scarlet as he observed them... the young, pretty girl and his own ex-lover.

While Frisk had been busy undressing Sans, he too had let his fingers wander to the zipper of her dress - it came down in a quick swish of fabric to rest at her ankles, leaving her completely naked for the two men to see.

What came next? She was unsure. Fortunately, she didn't have to decide. Grillby was suddenly upon them, so close to her that she could feel heat rolling off of him in waves.

"Tell me, Frisk," he murmured, taking her in while he spoke. "Is your magic enough to keep you from burning?"

Frisk truthfully didn't know the answer to that one. However, there was one way to find out…She reached out and grabbed Grillby's hand.

He was warm, there was no doubting that. But instead of the instant, stinging burn that she had expected, Frisk felt moderate heat. It was sort of like wrapping both hands around a mug of tea not long after the water had boiled. Grillby would be tolerable.

The pendant was fluttering hard against her chest, awoken from docility for the first time since the journey home from Aboveground. It really was amazing to be imbued with Sans' magic; who knew what touching Grillby would feel like without it?

When it was evident that she wasn't being burned, Grillby flashed her that same seductive grin again. "It appears I'm the only one unprepared." His voice trailed off in a soft chuckle, and mesmerized by the light he was giving off, Sans and Frisk watched him strip for them. It was not quite like the way Sans stripped for Frisk, nor did it resemble how she herself did it. No, Grillby was a tantalizing mixture of both.

Grillby somehow managed to stare both of them down as he removed his vest, one hand working on the buttons while the other went to the bulge growing in his pants. The vest hit the floor, and without missing a beat, the bowtie followed. Looking slightly less formal in just the white button-up shirt and black pants, Grillby continued his work, groaning softly as his hand continued to rub circles against his own crotch.

When his shirt came off, Frisk had to blink against the sudden brightness. Damn. Grillby had abs. Frisk had definitely never seen those in real life before. His newly exposed body seemed to roil and move under his fiery flesh, like trapped lava. Frisk might have accidentally swallowed her own tongue when his pants were removed, finally revealing the stiffening cock he'd been teasing them with. It was massive. Now as hard and straight as a pipe and about as thick, it stood out impressively from Grillby's flaming body.

"Now...Frisk. Darling, I'm afraid I've a bit of a problem." He purred, beckoning her over with one finger. Grillby moved his hips forward suggestively, making his erection bounce a little. "Care to help me?"

"How can I assist you?" Frisk tried to sound alluring, hoping it would mask the fact that she had never done anything like this before.

"Well, kitten. Get on the bed and put this -" He grasped his fiery member in one fist for emphasis "- in your mouth."

Frisk did as she was told. Grillby splayed himself on the bed, opening his legs wide for her to crawl between. Hesitantly, she licked the tip of the cock, a little startled by the heat that met her tongue. Grillby had made a delicious sound as soon as she made contact, though, so she soldiered on and took a few inches of him into her mouth.

"Ah! Oh, my. Sans has taught you quite a few things, hasn't he?" Grillby mused as she teased him with her tongue. "Sansy, come here...I've a use for your mouth as well."

Not needing any further prompting, Sans joined them on the bed. Hooking a hand through his ribcage, Grillby forced his mouth to Sans', eliciting a quick gasp of surprise and pleasure. Keeping a close watch on this enticing view as she sucked on the fire monster's warm dick, she watched an orange, forked tongue slither out of Grillby's mouth to tangle up with her boyfriend's. Sans was like putty in the man's hands, while Grillby was keeping an impressive amount of composure while Frisk blew him.

God, this was so different from Sans. For one thing, Grillby's thighs on either side of her made Frisk feel like she was sandwiched between two hot water bottles, while the penis threatening to hit the back of her throat was long and hot and dangerous. Bracing one hand on the mattress to steady herself, Frisk reached over to her naked lover and slowly began stroking the inside of one femur, loving the reaction it gave her. Now this was something she knew how to do, without question.

Above her, Grillby's composure was slowly slipping. His cock had started to drip, leaving white-hot fluid on her tongue. She hoped like hell that he wouldn't want to come in her mouth.

Sans was necking Grillby now, leaving the fire monster's mouth free. Every time Frisk bobbed her head, he jumped, forcing his hips further into her. He'd begun to pant steadily now, the sound low and growling in her ears. Occasionally he'd murmur little encouragements to her - "Absolutely lovely, dear" or "Bloody hell, yes!"

"Stop, stop," He suddenly cried, easing back from her a little. Frisk ceased her work, mouth a little sensitive from all the heat it had been exposed to. "Too much more of that and I'd have come. Sans, why don't you have your way with her, now? Make it good. Give me something... to finish to."

He'd grabbed his member again, and Frisk instantly understood that he was going to jerk himself off while he watched them have sex. Sans met her eyes, looking dazed. He hadn't even made his cock appear yet...the view and the attention from Grillby must have been far too distracting. After a few tries, Sans' own cock had appeared, blue and wonderfully familiar.

Pulling Frisk into a brief kiss, Sans hopped off the bed, moving around behind her. "Ass up, sweetie," she heard him mutter teasingly. Obligingly, Frisk lifted herself up, Grillby's cock still inches from her face. Feeling oddly exposed, Frisk bit back a small yelp of excitement when Sans' own dick rubbed against her very slick vagina, tantalizing.

"Ready when you are, Captain," Sans said to Grillby.

Grillby merely nodded, keeping his eyes on them unwaveringly.

Behind her, Sans thrust forward, making Frisk arch her back involuntary. Within seconds, Grillby was fisting his blazing hot phallus, crying out more harshly than she'd ever heard him. Focused on the agonizing feeling of Frisk's tightness and the goddamned look on Grillby's face, Sans was having a hard time keeping any sort of civility. He panted with exertion as he plowed deeper and deeper into Frisk's familiar body, feeling the sharp sensation of climax raking at him. After all this foreplay, it wouldn't take long.

Under him, Frisk was rocked hard into the mattress, bracing herself on Grillby's thighs so that she wouldn't land face-first in his furious masturbation. It was making a sloppy sound as pre-come flowed in rivulets down his hand and down his privates, sizzling as it made contact with the flames that composed the man's body. And how loud he was getting… Grillby's somewhat scary mouth was ajar, and he was letting out those same growling moans as his orgasm drew nearer.

Sans was giving her no mercy back there. This particular position made his dick rather friendly with her over-sensitive g-spot, and it was nonstop, overwhelming pleasure. Combined with the rather appealing sight not half a foot from her nose, Frisk felt herself nearing an orgasm as well. Her hair was matted with sweat, and she had never felt this uncomfortably hot in her life, but damn, this was so wonderfully intense.

Above both of them, Grillby was seconds away from coming all over Frisk. Things hadn't been too spicy for him in the intimacy department these days, and the invitation from these two was a welcome change. Frisk's body, curvy and supple and grabbable, was so arousing to watch as Sans plowed into her from behind. Her tits bounced forward with every thrust, and Grillby could feel the hot breath of her exhales on his balls. Oh, no, it wouldn't be long at all with this kind of view.

Sans had started to whimper behind Frisk, and she could tell without seeing his face that he would come in the next few thrusts. She didn't spare it too much thought, though, because her own orgasm was right there and if she tightened around Sans just slightly they'd both go over the edge. Grillby's hand was just a blur now, his hips rising far off the bed as he cried out wordlessly, begging to climax.

And somehow, messily, they all came together. Frisk's orgasm tore through her as she felt Sans' come filling her wet snatch, sinking her claws into Grillby's thighs. Grillby's come spurted out of him, shooting up to splatter Frisk's face and even landing somewhere on her back. Christ, is that a dick or a volcano? She thought as contact with the hot sperm made her flinch. It was like molten candle wax on her skin.

Though they had begun together, their orgasms gave out at different times, leaving everyone thoroughly spent and disheveled. If Frisk and Sans were alone, this would normally be the time they went about cleaning up, falling asleep somewhere in the middle of the process. However, things were different with a third party member, and the couple both looked at Grillby to see what he'd do next.

Spent from the wild night, his penis was slowly softening, coming to rest against his thigh. Head still tossed back, Grillby began to chuckle.

"Good Lord," he said breathlessly between laughter, "consider your tab taken care of for quite some time, you two."

There was no more that could be said or done there; their wild night had finally drawn to a close.

Frisk and Sans somehow found their clothes and re-donned them, looking incredibly rumpled. Sans' bowtie was clipped to the wrong part of his collar, and he'd missed a button putting his shirt back on. Frisk's dress was far more wrinkled than she had remembered it being, and one of her straps refused to stay up. Nonetheless, the happy pair bid Grillby farewell and stumbled home, long after midnight. It was strange to walk through the empty, silent restaurant so long after the town had gone quiet.

Sneaking up to Sans' room as stealthily as they could, he and Frisk immediately undressed and collapsed on their bed. What a night.

"What'd you think of that?" Sans questioned as they lay together, face to face.

"It was...really something."

"But was it fun?"

"Hell yes." Frisk smiled wanly. "But I think I'm too exhausted to move for at least a week."

"Not moving for a week sounds perfect. I knew there was a reason I love you."

Chuckling, she leaned forward to kiss him. "I've got to ask...what brought that on?"

Sans took a few seconds to give her an answer. "Well, I've seen the way you look at Grillbz, Frisk. Shame on you, sneaking glimpses at your boyfriend's ex-lover's ass." He was teasing her.

"Shut up, you. You're jealous because you've no ass of your own."

Sans jammed one hand under her arm to tickle her. "You caught me; I have ass envy."

The combination of his sudden tickle attack and the phrase ass envy sent Frisk into a fit of giggles.

"But honestly...I wanted to try something new with you. Sometimes...I dunno. I worry about not being exciting enough on my own in bed." His voice had sunk to a whisper, and the hand that had shot up to tickle her now laid lovingly on her chest, playing with the pendant round her neck.

"Sans, you're plenty exciting all on your own. Trust me." Frisk couldn't believe he felt that way. Being bored during sex with him was something that had never even crossed her mind.

Grillby had been fun, yes. He was easy on the eyes, of course. But Frisk knew without doubt that that would never equal how she felt about Sans. A physical attraction to the barkeep would never be as important as what she and Sans had...how much they loved each other. Sans would be her first pick, always. She hoped that he knew that.

"Sans, I'd choose you over that walking bonfire any day. I love you. Everything about you." Frisk bumped her skull against his. "You could say that you're my...verta-bae."

"Pfft. That was terrible."

Sans wrapped both arms around her in a tight squeeze. "Goodnight, Friz."

"Goodnight, Ducky Butt."

"...Please don't call me that."
