Dust sans/Dust is your best pal/friend, You don't know that much about him but, You had this weird feeling which sometimes interrupts you. You can't sleep at night that well, You always think of dust and even draw him til' midnight.

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.

Being the sister of the human in the Star Sanses you have become a target. They try to protect you along with everyone else, but you still manage to get caught. You become a prisoner in Nightmares castle, but it isn't as bad as you thought it would be, considering you once had to deal with abusive parents and all. It isn't way to bad, and you feel more apart of them then you have with the others. Maybe you could help them out?

You fall after being pushed of by the two people you thought that loved you, you thought that you would die. You wanted to die but not like this, ask you hit the floor everything goes black. When you wake up you find yourself in a comfy little house with a giant goat-man. Ok so I don't actually have a read description but you get the gists of it. It is a Yandere UnderSwap!Sans x Reader. It is written in the context that the reader is a girl but if you are male then well, Uuuuusseee your immmagggginnnatttion!!
