Sans x Insecure! Mask Wearing! Reader

A/N: ok real quick the reason there arent really any cross, fresh, ink, or unfreash is because I have no inspiration for those characters, I try to think of something but most of the time I have no motivation for them :/

Ever since you were out of highschool, you wore a mask. You didn't like the way your _______ looked on your face. You were afraid it made you ugly so you hide your face under a beautiful, sparkling carnival mask. 

You were afraid people wouldn't want to be near you if they saw you without your mask. The mask covered around your eyes, nose, and trailed down your jawline, only stopping just before your chin. 

You had moved to monster city just so you wouldn't be too out of place. You ended up meeting a group of monsters and befriending them. You mostly hung out with Sans. 

You were over at the coffee place having a friends night with the skele bros, Undyne, and Alphys. Sans threw in some jokes and Papyrus hated them. You leaned back on he couch just chilling. 

"Hey (y/n), do you ever take off your mask?" He asks. "Ya, but not around people." You say nonchalantly. "Well, we're not people." Sans says, seeming curious. 

You shake your head. "I'm not going to take it off." You say. Sans decided to drop it seeing how fidgety you got. 

He next day everyone went to the beach. You were wearing a tank top, shorts,...and the mask. Sans sighed, he was really hoping to see what you looked like. 

"Hey (y/n)!" Sans greated. He wasn't sure why he was so interested in seeing you. "Hey Sans!" You greet back. You sit on a towel that was layed under an umbrella. 

"You gonna go join with the others?" Sans asked. You shake your head. "Not really feelin' up to it right now." You say laying down. Sans looks at you with a slightly sad expression. 

Sans stared at you for a moment. You looked so peaceful. The breeze gently blew your hair moving it slightly. Your chest rising and falling with ease. He just wanted to lay down next to you and pull you close, whisering to you and...he shook his head. Sans then began to stare out at the ocean. 

It has now been seven months and Sans had finally realized he like you, a lot. Not once ever have you tooken off your mask, ever. Sans refused to take it off while you were at a sleep over, that would be mean and probably make you hate him. 

Sans was finally ready to ask you. He went over to your appartment. You texted him to just walk in and thats what he did. "(Y/n)?" He called. No answer. The door to your room was cracked open. 

Sans gently began pushing it open. "(Y/n)?" He caught a glimpse of you with putting on your mask, not being able to really see you face. You jumped, holding the mask to your face. 

"S..Sans! I..I didn't hear you come in." You say, begining to fasten the mask on you. "Ya, sorry...I called out for you but didn't hear an answer." Sans says. "S..so what's up?" You ask, trying to be casual. 

"I was wondering...if you...wanted to go on a date with me?" Sans asked shyly. You stared at him with wide eyes. "I..I, u..um, a..are you sure you wanna date me?" You ask nervously, sounding self conscious. 

"Yes of course! I...I really like you." Sans says. You blush under the mask. "I..if your uncomfortable with it i nderstand. I'll just.." "No, wait. I..I like you too. I..I accept your invitation." You say. 

Sans smiles happily. "Ok! Um so tonight's at eight?" Sans asked. You nod and Sans left to go get ready. 

That night you put on a gorgeous golden mask with jewls decorating it. You figured you'd make your mask pretty since your face wasn't to you. You arrived at the restaurant and saw Sans. 

He gave you a smile but something seemed to concern him. Sans thought you would have tooken the mask off. He doesn't care, he still really likes you. The date went well and a new bond grew between you both. 

It has now been two and a half years later, you and Sans were dating. Not once have you removed your mask. Sans had been trying to bring up the topic for a while but you kept avoiding it. 

Today Sans was determined to ask you and get you to take off the mask. He loved you and wanted you to trust him. 

You were in the kitchen nervously putting away clean dishes. "(Y/n), I'm home! Hey, I wanna talk to you about.." "Hi Sans nice to see you I'm tired now ok night!" You say quickly and rush off to your room. 

"(Y/n)." Sans started but you were already in your room. Sans sighed and went to your room. He gently knocked on the door and it creeked open slightly. Sans gently pushed the door open to see you sitting on the edge of your bed, arm wrapped around you, a few tears falling from the mask. 

Sans walked over and pulled over a stool to sit in front of you. "(Y/n), baby, what's wrong?" Sans asks softly. You just shake your head. "Is it about the mask? (Y/n), I just want you to trust me and so I can show you how much I love you." Sans says. 

"Y..you'll leave me...I'm ugly, I'm not like the other girls who have pretty model faces." You say. Sans looked at you sadly. "Sweetheart, I won't ever leave you, I love you." Sans says. 

"So please, take off the mask. There's nothing to be afraid of." Sans says softly. You begin to shake as you hesitate before slowly reaching to unfasten the mask. Slowly you begin to remove it, your head down though, hair falling in front of your face. 

You drop the mask and cover your face with your hands quickly. Sans gives a sympathetic smile. "(Y/n)...baby...sweetheart. Common my love, it's ok." Sans coaxes. 

He gently reaches and grabs your wrists, pulling them away from your face. For the first time, Sans saw your face. You looked at him with a scared and sad expression, one a puppy would make. 

Sans entire face erupted in a dark blue blush. He moved your hair away with both hands, looking at all your features. "I know, I'm hideous. You don,t have to stay with me anymo.." 

Sans then smashed his lips against yours. Your eyes widened but fluttered shut and kissed him back, tears leaked from your eyes as well. Sans pulled away and placed both hands on your cheeks. 

"Don't ever say your ugly. You are the most gorgeous thing I have ever seen. Why would you hide such beauty from the world?" Sans asked, his eyes boring into yours. You were at a loss for words. 

Sans began to shower your face in kisses, absolutely loving every part. You blush madly and squeak. Sans stands and picks you up. He lays you down on the bed and hovers over you. 

"You are so cute.~" He purrs, his pupils the shape of hearts. You blush even more, wanting to hide your face again out of embarrassment but Sans refuses. It seemed like forever Sans was loving and kissing your face. 

He soon stopped and laid down next to you. "I love you (y/n). You are the most beautiful, mystical, enchantingly cute being I have ever seen. Don't forget that." Sans says softly, tucking your hair behind your ear. 

You smile and Sans just eats it up. He adores you so much. You began to grow tired and snuggled close to Sans. Sans pulled you close and kissed your head. He began to rub your back in soothing circles making you practically melt. 

"Goodnight sweetheart." Sans coos. "Night Sansy, love you." You mutter back tiredly. 

The next morning Sans woke up to see your beautiful face. He sighed dreamily and began to take in your features. Sans then began to kiss your face softly. You wake from this but just let him love on you. 

"Morning my precious love.~" Sans coos. You hum and snuggle him. "You think your ready to see the others today?" Sans asked running a hand through your hair. You grunt. Sans chuckles and kisses your forehead. 

You did end up seeing the others without your mask and they all loved you still. You couldn't have been more happy. Sans was the best boyfriend ever.
