(A/N:The photo above is so cute! ^~^ Anyways,sorry that this took a while,i had to get some inspirations from other books or one shots like this,anyways,ENJOY!^_^)
Sci (science sans's nickname)has been overworking himself lately to try and recover A LOT of lost research after Gaster suddenly disappeared.He worked early in the morning til late at night and MAN! is he so stubborn! You kept begging him to get some sleep but he would just turn down your offer. You really had enough so today, you were going to make him sleep NO.MATTER.WHAT!
~at sans's lab~
"SANS!"
"H-huh?!"
He shrieked and jumped a little in his chair as you slammed open the door to his lab.He looked towards the doorway and spotted you before he sighed and turned back to his papers. "Please (Y/N),for the last time,I'm not going to sleep!" He said before slamming his hands on the table, frustrated and annoyed at your countless attempts. It scared you there for a bit but you quickly regained composure and stomped over to him.You grabbed his collar and dragged him to his bedroom, him struggling under your strong grip (let's just say...he's shorter than you).
Once you reached his room,you gently placed him down on the bed and held him there for a bit since he was still struggling but soon gave up since he knew there was no stopping you.You smiled victoriously and place a quick peck on his forehead, making him blush a deep blue hue,before you stood up to walk off, thinking of giving him some alone time. It's weird to stare at someone when they sleep...
You felt your arm being pulled back, making you stumble a little.You turned and looked back at him as he blushed deeper before shyly asking you.
"Can you sleep with me...?" You don't know how he managed to pull that shot but still smiled and nodded your head to his offer, blushing like a tomato.
Sans smiled brightly at your answer and moved to one side of the bed to make space for you.
You climbed into the bed and faced the other way(away from sans that is),your blush kinda fading away but was soon replaced with a big one when you felt sans's arm wrap around your waist and he nuzzled his head into the crook of your neck. You turned to face and accidentally glide some fingers against his ribs, making him giggle before covering his mouth in shock. You smirk evilly before hitting his sensitive parts on his ribs making him burst out in laughter as he tried to get out of your grasp.
You smiled at his cute laugh before removing your fingers as he panted, trying to get his breath back
He smiled and pecked your soft plump lips. You were shocked at first since you really didn't expect that but soon melted and kissed back.He pulled back and said
"Thanks for getting me out of that hell hole...kinda"
You giggled.
"It's ok,as long as I get to spend time with you"
You hugged him tightly as you heard a 'click' behind you.You turned around and saw papyrus in the doorway with a camera but quickly ran off as he met you eye-to-eye.You didn't really mind him since he is a small skeleton child after all.You turned back to Sans and saw that he was blushing the color of a blueberry.You chuckled and gave him a quick peck on the lips before falling back to sleep next to him.

Such a cute couple,don't you think so too?
