Ullo everyone. So I decided to make a lemon (<- I hate that term so much) between US!Sans (or as everyone calls him Blueberry for some reason) and the reader becuase everyone is fucking obsessed with him when it comes to Underswap.

(Y/n) is just a girl who loves the sea. Living with her father in a beach house, (Y/n) discovers an abandoned ship in a secret glade. As she takes a closer look at the ship, she finds that is not abandoned, but being lived in by a famous captain. Captain Aki, and her first mate Fuyu. One day, (Y/n)'s father was killed by the emperor's guards. Her life in Matsumoto Village, became ever darker. That day, she started to live with her new friends Aki and Fuyu. Ten years later (Y/n) is now 18 and ready for adventure. The village loves her, she always fights against the emperor's guards that cause trouble. As (Y/n) was fighting some guards, a skeleton dressed as a pirate runs into her. "Who are you?!" (Y/n) asked while running away from the guards along side the skeleton. "They call me Ocean, Captain Ocean!" He said smiling.

You don't know he loves you. You don't know that he will kill for you. You will be his, no matter what.

The first two chapters are bad I advice you not to read! You should know what this is it's literally in the title! If you want, and if you must, the sin is on my last chapter. Yet another cringey old fic of mine!!!

This is a very high s e x u a l level so if you don't like it then I'm sorry!!

Monsters had been on the surface for about a month, Stretch, blue's bro, had been included in a mass murder. He can't stand to lose another that he loves. So when he sees you, he decides to follow you home, and start smiling you love letters...and little presents too~

Hi! My name is Y/N! I recently fell down this mountain called MT. Ebott! I met a cute creature that turned out to be a monster. I stayed with this goat person I like to call goat-dad in this place called the "ruins" I just came out of the ruins to meet papyrus and sans. Papyrus is lazy and punny while his brother , sans , is cute and clingy. He acts really shy around me...I wonder why...

You are locked below ground where nobody can find you. Chained to a wooden post in a dark, cold room. You are left with no memory and pain all over. You are left there for unknown reasons. That is, until you are found. Someone has come to save you. And they love you very, very much.

Sans has always had a fascination toward humans. When you arrived his innocent interest became a disturbing obsession. Over a short amount of time you come to realize that the monsters of the underground weren't as nice as you thought. Monsters are disappearing and friends you made along the way are starting to become suspicious of you. You begin to question your own sanity and can't help but wonder if this is some kind of cruel punishment. The deterioration of your mental health makes you question whether TRUE LOVE is on your side or not. ~~~~~~~~~~~~~~~~~~~~~~~~ I DO NOT OWN UNDERTALE I DO NOT OWN SANS I DO NOT OWN THE AU ALL RIGHTS GO TO THEIR RESPECTFUL OWNERS.
