Undertale ASMR: Sans Does Babysitting

I decided to take a break from my Oz project to do that Sans project I was was considering a while back! You're Frisk (and also the player), post-true end. So, yes, massive spoilers. Also, just FYI, I am completely open to suggestions and requests! I'll attempt anything you like, as long as I'm familiar with the fandom or character! When you know that Sans knows that you know basically everything, babysitting gets a little bit... awkward.
