Burning Desire~ (Underlust grillby x Reader)

The hottie

Authors POV

Well, here's a little summary of how you got to where you are:

You were drunk and dared to go down mount Ebbot, your friends were saying it also in a drunken state but as a joke and to their surprise (and worry) you actually did it

You were greeted by toriel who you escaped from

You were captured by sans because of your sexy appearance, your, at this moment, his pet but he doesn't want to be known as a rapist so he's waiting for your consent to actually 'do it', meaning your (luckily) still a virgin

Today Sans was taking you to grillby's for abit of a treat, taking the frase 'take me out to dinner before you fuck me' a liittle too seriously

Y/N's POV

Today I'm going to be meeting sans's friend, grillby. We're in his room and he's deciding what I should wear, the choice is sexy slut or sexy whore

"Hmm, which one would you like, slut~ cute or sexy?~" you pointed to the sexy whore outfit. Sans's idea of 'cute'.

"Good choice~" he threw you the clothes and you got undressed and put it on, you could never change without him watching

You then started to walk to grillby's with sans. As usual and expected you get a bunch of dog whistles and 'hot DAMN, that ass~' from the other monsters, every time they did so sans pulls your chain to show off the fact that he has a sexy pet

You enter the strip club with sans and you both sit at the bar. You spot the bartender and look at him up and down, admiring how he looks, of course you quickly avert your eyes away to avoid making sans jealous. Been there, done that, never again

The bartender comes over and dog whistles at you "I like the prostitute you've hired, sans, mind if I take her when your done?~"

"Back off, she's my pet" he tugs on your chain to prove it "aren't I, slut?~" you hated being showed off like this but nodded. "Oh, thats a shame... Say, how much do you want for her?" He smirks at you.

"Bud, what did I say?" Sans was getting overprotective now, he always does. "C'mon~ even if its just once?" He tries reasoning with sans but he just keeps looking at you, lust in his eyes. "Nah, she's still a virgin and her first time will be with me, alright?" The bartender growled but just nods

"Alright, I'll just admire from afar~" He winked at you. Damn he was hot - no pun intended. "Good, two fries please" and its back to normal, at least, if normal is his eyes still filled with lust.

"Did you even ask what she wants?" He looks at sans, raising a eyebrow. "She will eat what she can get" he growled back. The bartender left to go and cook the food.

Since he was doing everything (apart from the stripping) you assumed he was grillby.

"Hey, eyes over here, pet~" You almost forgot about sans and looked away from grillby and looked at sans. "I want your eyes to always be on me, got it?" He sounded jealous so you just smirked at him. "Got it?" He pulled your leash this time. "Y-Yes..." Your smirk faded

~20 Minutes later~

Grillby comes with the food

"Jesus, what took you so long? The place isn't THAT packed." Sans raised a nonexistent eyebrow at him. "Sorry, I got distracted and the first batch burned..." He winks at you, you blush, now knowing what his 'distraction was.

"Yeah, fine" he just ate his fries and signaled you to eat so you did, despite you not being hungry

"So, what's your name, sexy?" You blushed while sans growled "its y/n, your not going to settle with just watching from afar, are you?" "Nope, thats a lovely name y/n~"

Sans got mad now "yeah, we're leaving shortly." Grillby looked abit sad and thought of something

"Sans~"

"Yeah?"

"Don't you need to pay your tab~"

Sans sighed deeply "no, I will not pay you y/n"

"Fine..." He grumbled, clearly upset

You blushed at grillby, he was just about to give up thousands, maybe even millions, of gold for you. He winked at you and you saw a slight blush on his cheeks, you didnt know the lusts could blush, only fuck senselessly

Sans got upset "ok, we're going now" he took you by your chain and left as you mouthed 'bye' to grillby and got dragged along with him
