UNDERTALE: Sans x Frisk One-Shots!

Punishment

"There are 206 bones in the adult human body, blah blah blah, in total they weigh about fifteen percent of a person's mass, blah blah blah..." Frisk plopped her biology book on the floor, a frown etched all over her mouth. Her small legs kicked across the floor impatiently; this book was not telling her what she wanted! She had to find another way to find her answer...

At that moment, an idea popped in her head, cueing the human girl to trot over to the sofa. Peering over the seat, she spotted a familiar blue jacket and began to tug on it lightly. "Sans!" She pestered to the sleeping skeleton. "I'm bored, play with me!"

The monster on the sofa swatted her hands away, slightly annoyed of the human's rude wake-up call. "Frisk," He said groggily. "I'm tired, leave me alone and let me sleep..."

"It's only the afternoon, Sans!" Frisk complained, puffing her cheeks. "Pleeeeeasssseeee?" She received no answer from the skeleton as he was almost on the verge of falling asleep again. Pouting, she grabbed onto Sans' hoodie tightly and pulled him of off the sofa. She raised him above her head at the speed of light.

Only now did Sans seem fully awake. "Whoa, wha-" He was cut off when he realised that he was a few feet off the ground. Below him, Frisk smirked victoriously, though she was secretly thankful that Sans wasn't too heavy for her to carry. "Hehe..."

"Kid...?" Sans raised an eyebrow as his voice trembled a little. "What are you-AHHHH!!"

He was cut off when Frisk took off, running back and forth in the living room while carrying Sans above her head. The skeleton had no choice but to flail his arms and legs helplessly as Frisk's running speed increased. "KID!! PUT ME DOWN NOW!!!"

Frisk only giggled in joy at the sound of Sans' cries, until her foot accidentally met with a littered banana peel.

BA-BUMP!!!

Sans felt a sharp sting on his head and placed his right hand over it. "Errr... Ouch."

"Sans!" The human girl crawled over to the skeleton who was rubbing a red spot on his skull tenderly. She could see that his health points was diminished to a half and a wave of guilt rushed through her whole body. "Sans, I'm sorry!"

Her left hand tried to touch the scarlet spot on his head but he brushed it away and pouted his cheeks angrily. "Hmph!" He refused to talk after that.

... Well, that was until Frisk decided to smooch the injury on his skull.

It sent a shockwave through Sans' body as his cheekbones turned azure blue. "K-k-kiddo-?" He stuttered, completely tongue-tied. "W-what...???"

"Do you forgive me now?" An innocent yet cheeky smile was on her lips as she brought her face closer to his. It was probably five centimetres away now. Sans could feel his shoulders shiver and a few sweat drops on his skull. "K-kid, what are you-"

Frisk slowly closed the gap between them as she leant in to give Sans a small kiss on his teeth. A small silence ensued between them before a small moan escaped from Sans' mouth. His face was fully blown blue as the pinpricks in his eyes turned into flustered orbs of white. His whole figure collapsed to the floor the second time that day.

Meanwhile, Frisk was grinning from ear to ear as her 'plan' had worked. Not only did she know how heavy was a skeleton, but she also gave Sans a little punishment for not bothering to play with her. The human girl pulled out her diary and started scribbling her entry in it.

Today, Sans didn't want to play with me, so I punished him. He was so FREAKING cute!

A/N: Short one shot is short one-shot. I'm so sorry if this was too short. ;-;
