Just a heads up not the greatest at creating stories. Anyway you'll be a different reader each time but with a different Sans. I won't upload much but I'll try to upload as much as I can. Warning: there will be smut, kissing, maybe some sexual content, swearing, anything traumatic like abuse, and you being a hybrid reader like a Neko. Also none of the art is mine, all credit of art goes to the artists. So try and enjoy my terrible writing. 😄

You climbed the famous Mt. Ebott to prove to a group of your friends that humans don't disappear when they go up the mountain. While walking around the peak, you trip over a root in the ground and fall forward, expecting to hit the ground. Instead, you were met with open air. As you fell down the large hole, you let out a shrill scream before hitting the ground and blacking out. When you wake up, you find yourself in the Underground where monsters had been banished to by the humans. You meet several monsters down in the Underground, some becoming friends and some becoming enemies. One particular monster though, has been making your heart flutter and your tongue get tied. Sans the skeleton. A new threat appears when a human that had been thought to be dead comes back and threatens you and the entire Underground. Will you be able to stop them or will you be used as a puppet and watch your friends die? Maybe the only thing that can defeat LOVE is love... Author's Note: this was my very first story so sorry if there's bad grammar or confusing scenes, enjoy my awful writing! ((COVER ART IS NOT MINE))

Sans has lived through countless timelines. He's seen the kid make friends with everyone, only to give up in the final moments. He's seen the kid killed, over and over and over again. Sometimes, he'd even done the killing himself. And no one ever remembers. Not even the kid herself. It's an exhausting cycle, one that never seems to end. But there's something different about this run. Another human's fallen down... the kid's sister.

You, a Witch, owned a potion shop in Ebott city where Monsters, Humans and supernatural beings lived in relative harmony. You had once had a chance encounter with two skeletons Monsters but to your surprise, both of them were supernatural beings! Quite rare for Monsters to be. Even though you had a hectic meeting with the skeleton brothers, the three of you became quick friends. The vampire skeleton Sans helped you around your shop when he could while his brother Papyrus, a werecat, came around to show off his partners...? Yeah you thought it was a weird way for him to bring you extra customers but highly appreciated! Everything changed when one adorable blue skeleton invited you to a yearly masquerade party and something unlocked inside two skeleton's minds when they saw you getting all nice and comfy with another Monster. They couldn't let their beloved witch be taken away now could they?

[This is old & terrible. Read at your own risk] When a situation with a dying human ends up with you absorbing their soul, you panic (like any unprepared monster would). Suddenly Undyne is hunting you down, so you rope the mysterious skeleton next door into helping you. Which he does--in a very Sans way. And who knows? Maybe pretending to be his girl will pay off. | - Classic Sans x Monster Reader - Fake dating turns into real dating - One (1) very mysterious skeleton & one (1) very awkward reader - Papyrus is so sweet and innocent, I love him - Monsters really are in the wrong for killing children tho - I love happy endings and hate tension so expect an easy, relaxing read
