Ch. 1 What are These Feelings?

This is an Undertale fanfic which is a Papyrus x Sans story. It will involve a lot of smut. Other ships that will be involved are Flowey x Frisk and Undyne x Alphys. None of the images are mine. There will be adult content. (Ex. Profane language, sexual activities). This is yaoi, and yuri. Frisk will be a male in this. None of the images used are mine, unless I say they are. They will most likely all be taken from the Internet. I will update once a week, unless I write a super short chapter.
