Need help finding something (Vore-Warning)

A few years ago I saw a comic (or possibly a short animation, I don’t remember which it is), about two Kobolds using a pair of large brushes to clean a T-Rex. One Kobold starts brushing at the T-Rex’s mouth, the other starts at the T-Rex’s dick and ass; but then the two Kobolds switch places by brushing/cleaning further into their respective holes until they pass each other halfway-through the T-Rex’s intestines (I also think one Kobold gives a blowjob to the other while still inside the intestines). I have looked everywhere, but can’t seem to find any trace of this comic/animation or the artist who created it.
