Teacher G!Sans x student reader

"Great, what a good day to be stuck in this goddamn school!"

I yelled out to myself sarcastically as I held on to my (f/c) hoodie close to my face. It was raining heavily today.

I had already went back home at first,but you forgot to bring your goddamn school project.it was an important project because you need to hand it in the next day,and there were a lot work too do with it.

You decided to go back to school for a while,but luck wasn't at your side.the main door of your school locked.you decided to go back home and you were greeted by a storm.you want to call someone,but you remembered that you left it at home.

Just great!

You stood in front of the main door while holding the door handle tightly.the wind breezed roughly made the rain splashed on your face and your clothes made it soaked wet.

the lightning flashed and it followed by the sound of loud thunder.you yelped as you sat on the wet cement and held the back of your head in fear.you really hate the lightning and the sound of thunder booming.you just hope that it will be over soon in desperation.

*Doll?what are you doing at here?

You heard someone calling you from behind.you turned around and saw a familiar skeleton,Gaster Sans.you felt so happy and relief at the same time.he was your PE teacher and he preferred to call as 'teach' or 'G'.

The two of you were buddies because the two of you share a same interest, that was make a bad puns.you usually call him as G.

"G,I want to take my school project.it is really important!"

you said.he nodded his head and he said that he had the key for the main door.as he said it,there was a loud thunder and all the school's light turned off.you yelled in fear and hugged him,buried your face on his chest.you can't help yourself but cried on his chest,scared.

he quickly took out the key and unlocked it.he immediately locked the door after the two of you entered the school.everything was dark so he took out a lighter from his pocket pants and turned it on.he took a glance at you whom still crying.he hugged you and rubbed your back.

*shh...don't worry.I'm here with you.

He comforted you.he felt that your f/c hoodie was soaked with rain.he brought you to the teachers room.he took out his spare clothes from his drawer.he showed his clothes in front of you that was sitting on his chair.

*wear this or you'll get a cold.

Without any words,you take his clothes and get changed.you wore an oversized T-shirt with a pair of shorts that reached your knees.

*wait here for a moment.

He was about to take a step but you stopped him by grabbed his wrist.

"Please,don't leave me alone..."

You said as you lowered your head.he stood for a moment,looking at your form.he took a chair and sat on it beside you.he took a glance at you from the end of his eyesockets.you sobbed lightly with tears swelling inside your eyes.he chuckled lightly,made you gave him a glare.

"Why are you laughing?"

You asked felt irritation rose in you.he put his chin on his palm as he looked your f/c orbs.

*it is just,you're cute when you're crying like this.

He said with a small smile drew on his lips(??).you blushed 50 shades of red by his statement. You hid your face using his t shirt that you wore.

"I-idiot!I'm not cute!"

You stuttered.Sans chuckled again made you looked away in embarrassment.the truth was,you have a crush on him ever since he started his debut as a PE teacher.you felt like heaven that the two of you were alone,but it was interrupted by this stupid weather.

You suddenly felt someone held on your chin,made you to turned around.you felt something warm against your soft lips.your eyes grew wider when you realized that your PE teacher, kissed you.you mentally squealed and blushed more by his blunt move. after a minute,he released the kiss.he chuckled as he saw your flustered look.he pulled you into a hug using his right arm.you rested your head on his chest,felt the warm of his embrace.

*I love you,dollface.

"I love you too,Sans.."

You didn't regret to be stuck at school.
