Forced Invation

You watch over the counter as the bartender swiftly mixes Sans' drink behind the bar. He poured a vivid green mixture into a sleek cocktail glass and smoothly slid the finished drink along the counter, landing it directly into Sans' waiting palm. From how easy he made this look, he must've been making drinks for Sans for a while.

You turn to Sans, who's paying no mind to you, lifting his drink to his mouth. Pausing, he turns to look at you with a confused expression. "What..? You wanna try some?" you nod your head without hesitation, you're so hungry, you just want to taste something, anything. Sans cracks a soft smile, before sliding the glass toward you. "Heh, alright here." You snatch the drink, bringing it up to your lips. "Ya might wanna go slow-" Before he could finish his sentence, you take a deep gulp, not leaving a moment to prepare yourself for the sudden and intense sensation that washed over your tongue.

Your taste buds are hit with a powerful burst of sourness and tangy flavors. Your body stiffened as you tried your best to withstand the taste. Just as the flavor started to fade, it quickly got worse as the taste of alcohol kicks in, burning and numbing your senses as the drink traveled down your throat, leaving a trail of heat in its wake. "Ah! Eugh!" Tears form in your eyes as you clutch your stomach in pain. The sound of Sans laughing maniacally doesn't help at all. "Pffft..! Hahah!" He smacks the table, trying to collect himself. "Heheh... They call it 'Sourfire' for a reason doll."

A wave of nausea hits you as the burning in your stomach began to die down. "Ugh, how can you drink that..?" You ask weakly, still holding onto your burning stomach.

Leaning on his hand, he smiles sweetly before answering almost immediately. "Monster drinks are different from what humans got back on the surface. Strong, eh?" It feels odd to have an actual conversation with him... I think I like it.
You didn't understand why, but for some reason, his presence wasn't intimidating or scary. It was weirdly comforting.

You nod in reply, "My throat still burns.." You complained to him. His smiled faded slightly as he took a swig from his drink. "It'll fade."

Grillby comes by, setting a plate of freshly cooked, golden crispy fries before you. You can feel your mouth watering as the salty savoury aroma hits your nose. Before walking away to tend to the other customers, Grillby took a look at the two of you, smiling beside each other, still looking shocked that you're "with" Sans.

As soon as Grillby disappears, you dig in, devouring the fries whole, without taking a moment to savour them. You were so hungry you didn't have the energy to mind Sans picking a few fries off your plate every now and then.

Finishing half the plate, with some help, you lean on the counter happily, turning to look at Sans. "You full already?" He asks, his voice sounding like he genuinely cared if you were satisfied. You sigh, feeling full for the first time in days. "Mhm... Thanks for getting me this..." Trying to hide your embarrassment, you offer him a smile. "Alright we'll get the rest to go," Sans flags down Grillby, gesturing to the fries.

As you patiently wait for the container to arrive, you catch a quick movement from the corner of your eye. You turn your head and observe Sans, who appears to have jerked suddenly in his seat before swiftly swinging his stool around to face a new direction. As you turn, a wave of shock and fear washes over you, causing your entire body to momentarily freeze in place. Your eyes widen in disbelief as you behold a massive white dog, adorned in shining silver armour. Two more slightly smaller hooded beasts loom ominously behind their leader, their large battle axes reflecting the lights off them.

Sans harshly swats the dog's large paw off his shoulder, sneering viciously at the posse behind him. "Fuck do you mutts want?!" The dog's expression remains the same, almost as if he was used to treatment like this from Sans. "We have news about your brother. You're coming with us, his orders." Sans groans in response, his usual irritated persona returning. He slides off the stool, looking back at you and nodding his head for you to come with him.

Staying behind Sans, you relied on his bulk as a protective barrier while the two of you trail behind the group of guards. Eventually, you all arrive at a secluded booth nestled in a dimly lit corner. The dogs pile in the booth, awaiting you and Sans on the other side. Setting a hand on your shoulder, he silently urges you to sit down first. As you slide into the booth, he follows, moving you up against the wall.

"So?" Sans speaks out impatiently. "Why'd you mutts drag me over here.." he rolls his eyes, dismissing his question. "Why couldn't Pap come here himself?" The middle dog takes out a piece of paper and slides it in front of Sans. You glare over trying to distinguish any words, but the print is too small. Sans reaches for the paper, pausing to examine it. "A rank-up?" Sans scoffs, "So he's too good to be seen in Snowdin now, is he? Boss of all monsters should know I don't care about dumb ceremonies like that." Setting the paper down, he leans back in the seat, crossing his arms. "Can't you see I'm dealing with my own shit? Put me down as a no."

The hooded dog on the far right begins mumbling a low growl, suddenly snapping his sharp glare at Sans. Without warning, the dog stands up, slamming his paws onto the table, the loud noise causing the bar to go silent for a few seconds. Locking his fierce eyes on Sans, he speaks through gritted teeth. "Look, you weren't originally invited due to your low class, and lack of manners in front of royalty." The middle dog rests a paw on his back, settling him down, and he continues. "But Commander Gaster demanded you attend the promotion, he went through a lot to get you an invitation." The middle and biggest dog speaks up, his voice being much deeper than the other. "Commander Gaster sent us here to tell you that you're coming, we aren't asking." Sans laughs, "So now he's resorted to forcing me into going to his dumb event. Yeah, that sounds like him alright."

The three dogs stand up suddenly, the middle one's massive armour banging into the edge of the table. The biggest dog speaks out again, "It's good to see your cooperation for once, Sans. It's tonight, do not be late." The dog turns back, " Oh, and make sure you and your..." The dog looks at you for the first time, your eyes meeting with his, sending a rush of adrenaline through your veins. The dog seeming unsure of your species, continues, "...Thing... dress appropriately for the occasion."
