WARNING: SANS X READER ACTION THAT IS CUTE!!!
====================
You were on the surface and you found a video while you were unpacking. You looked at the cover and read 'When Sans danced' you smirked and 'accidently' tossed it with your stuff as you dug around. After you putted away the last book for your collection, you pulled out your laptop (you may or may not have trolled Papyrus a few times) and putted the disc in.

You clicked play and saw Sans dancing like a royal. Walceing. You smiled as you watched, in the video it looked like Sans was enjoying himself. "WHERE DID YOU GET THAT?!?!" You yelped and closed your laptop lid, turning around and seeing Sans blushing. "I... I... I found it..." You answered nervously, afraid that Sans was going to hurt you. "STAND UP PLEASE." You putted your laptop on your bed and stood up, soon blushing as Sans moved your hands in a walnce position. Sans had one hand on your waist bone and the other holding your other hand up.

"YOU REMEMBER HOW THE MOVEMENTS ARE?" You nodded before moving your feet in a slow and easy pattern with your brother. You smiled at Sans, who smiled back as he slowly swirled you and brought you close before repeating the swirl again. You both shared a smile as you both moved in a circle, you both separated, still holding hands before pulling together again. "YOU'RE DOING GOOD FOR YOUR FIRST TIME." Sans complimented, you smiled but soon blushed a storm when Sans dipped you.

"Gotcha~!" Sans said in a very teasing voice, your cheek bones were (color of magic) as Sans looked into your (color of magic) pupils. "YOU KNOW WHAT HAPPENS NOW~?" Sans asked, you slowly nodded as Sans lifted you up to stand. He putted a gloved hand on your blushing cheekbone before placing his teeth on yours. You leaned into his touch and moved your arms to his shoulders as he cupped both your cheekbones in his hands.

*DING*

You both looked over at Papyrus, who held a camera. "GET RID OF THAT IMMEDIATELY!!" Sans ordered as he chased Papyrus, you started to think of what just happened and blushed.

'Did I just KISS my brother?!'
