Undertale - You're gonna have a bad time

This feels like a good place to make a confession:
I have not played Undertale, despite having an obsession with its characters and this gallery in particular. On top of that, I would really like to cosplay as Sans, because I think I fit his personality very well and body type well enough. I would have played Undertale by now, but I don't have a computer to play on. I don't think it would be right for me to call myself a fan until I at least do whatever the second best thing to playing is, like watching a let's play or something.
Just had to get that off my chest.

this looks like it would be very easy to replace those images with NSFW ones
