The barrier to the human world were already destroyed and the monster and humanity have been together for about a long time.

You..your name's frisk..

Your the one who help and brought peace through the monster and human war.

The war were a chaos but you succesfully make a peace.

You got some many friends and even a step-mother named, toriel.

Toriel is the bestest mom you'll ever had and she always make butterscotch pie for dessert and you like it. Toriel have taken good care of you and now your all grown up to be a good 19th year old girl.

You know that toriel was the former queen of underground and you pretty much like it and always want to find out more.

So! You ask your two bestest skele-bros,Papyrus and Sans. They teach you about some history of the ruins and underground with the help of the amazing doctor alphys and undyne but mostly alphys.

You learn so much from them, from the beggining how underground were made and how toriel and asgore g-nnever mind.

Sans and papyrus always educate you like sans educate you about using magic and papyrus always show you how to cook spahgetti with undyne and you pretty mucchhh learn all of the needs of an education from alphys and you even learn anime from alphys.

But recently, you've been hanging out with sans really often and it pretty much make your feeling for him developed, what do i mean by developed? Well, you've been secretly crushing on sans since your 14 but you thought that he's to old for you but you know that monster age are pretty slow on the human world so when your 19th and he'll be 22th.

So knows the change to go leveled up your relationship with him.

"Hey sans, what are you doing?"
Yous said as you suddenly jump from the top of the couch and landed perfectly to the cusion.

Sans:"o-owh, hey there kiddo, i was just watchin this cool anime that alphys just told me."

"Is that the one that trending right now, if i'm not wrong, One Punch Attack.Isn't it?"
You said as you raised a brow.

Sans:"Rightio Bucko, your right the prize will be given later when your older then me!"
He said with a grin as he's gaze move back to the TV.

"Huhhh...sans let's do something other then this.."
You said as you looked around for fun but sudenlly papyrus came in.

Papyrus:"FEAR NOT,I THE GREAT PAPYRUS HAS ARRIVE!"
He said as he kick the door open as you flinch and fell with a thud.

"Ouch..h-hey there papyrus"

Sans:"Nice one bro."
He said as he look at papyrus and chuckled a bit as he looked at your falling form.

Papyrus:"HUMAN,WHAT ARE YOU DOING ON THE GROUND? ARE YOU GONNA DO SOMETHING TO IT?"

"N-no..i was just fell back, why would i do something to the floor.."
You said as you scratched the back of your head.

Papyrus:"WELL OKAY THEN I THE GREAT PAPYRUS SHALL MAKE US DINNER OF SPAHGETTI AND I SHALL LEAVE YOU GUYS ALONE HERE"
He said as he go brought the grocery bag he brought home earlier to the kitchen and leaving you alone with the one and only sans, the pun master.

You looked at sans who was watching the famous, one punch attack and he look like he enjoyed it.

You got some idea in your head and you got back to the first location you have always been, beside sans.

You grin mischiveously as you looked at him as he caught you and raised a brow, even if he have a brow.

"Hey sans i have som-oops.."
You said as you approach him and tripped on the rug as you trip, you unacidentally slammed your lips to his.

Making his face a bright blue as his one pupils turn blue with an aura got out of his blue ones.

You just smirk and continued to kiss him eventually he melted to the kiss. He licks your bottom lips for entrance, you were surprised how fast he liking this.

You just responded with opening your mouth.

He's blue tounge go deep inside your mouth as it go around and explore his new teritory.

You were a moaning mess as your tounge rub each other.

After a good 6 minutes of that you pulled away.

You looked at him with a red face.

He was flustered and opened his mouth to say something.

Sans:"are you doing that on purpose?"
He said as he smirks with a blue glowing half lidded eyes.

"Maybeee~"

Sans:"Don't lie to me kiddo, i know how you do your 'things'and i like you too kiddo..just don't tell anyone.."
He said as he ruffled your hair.

"Yea okay then.."
You said as you shifted yourself next to him as you guys continue watching.

Sans:"wanna try that again later?"

"Sure~if you don't mind."
You said as you guys watched tv again and you guys didn't know that papyrus was jaw-dropping behind the wall seeing you and sans kiss.

Papyrus:'OH,MY,BONE.'
