OK

LoL Sans, this is unappropriated, but so Anime xD

Also, Frisk reaction would be everyone else, me, I would just stand beside them and be like:

"Why? You guys ship alternate versions of Sans with one another. And you ship a literal child (which probably ranges from the age of 10 to 14 years old) with almost every possible adult of this game series, which ranges your dislike/disapproval of 'incest* a rather small issue compared to the mass Ophidiophilia, Necrophilia and self-cest you commit on a daily basis..."

Yes, and I would totally say that, because that's weirding me out more than shipping two brothers with one another xD
