Don't ask where I got the idea... I just learned about Error Sans and I've always loved Aftertale Sans. I instantly fall in love with every Undertale AU, even UnderFell. Most art of it is just creepy. I'll do more Sans au ships if wanted. For example; Sans x Underfell Sans Swaptale Sans x Sans Error Sans x Underfell Sans Error Sans x Swaptale Sans Sans x Aftertale Sans Gaster Sans x Sans Aftertale Sans x Underfell Sans Gaster Sans x Underfell Sans Gaster Sans x Error Sans

This includes a Sans X preferably a female reader. It's your choice though! ^-^ this isn't a lemon! So, don't worry. Just cuteness. But, slight dirty references here and there. Nothing to big though, haha. Also, this is more of a one shot kind of thing, so sadly they're isn't going t be a continuation to this story. It had just turned dark outside, the moon was full tonight. You decided to walk over to the skeleton brother's house and invite them to go star gazing. You live quite close to them. They had never seen the moon or stars before, everyone in the underground hasn't yet. But, tonight, shall be the first. Sans is the only one in the house and answers the door, you ask him if he wants to go star gazing with you. He accepts. Now, only you, him and the sky are out on the field tonight. ***not my art! All credit goes to the wonderful artist.***
