Requests: Part 4! (Patreon)

Alright, back from my mini-breather with the next part of the request batch!

I was going to just use the original Sans sprite for this, but...ehhhhhhhhhhhh, wasn't feeling it. XD

So, I ended up using a custom one instead, and it helped out with actually giving him some expression!

Learnin' how to fade stuff out of the gif was really cool too, and I think the spank mark fading away is satisfying to look at.

See you guys in the next part!
