I’m imagining this in Thorax’s normal speaking voice.
I like to think that Thorax would be able to do the voice if he hung out with Rarity long enough to get her mannerisms and tone right.
Sometimes I like to imagine myself suggesting to a pony friend that we practice making out with each other, just in case we meet any girls. If hes cool with that, I could suggest doing the heavier stuff later on :D
I want to see a fic based on this scenario, but with Spike realizing that Thorax didn’t put genitals on Rarity’s body (due to Thorax’s lack of familiarity of ponies and nervousness), leading to an awkward moment between the two, before Spike says that Thorax doesn’t have to change, etc, etc. You know the drill.

It’s not much of an idea, more of a reality. Not Gay Changeling art has been around since ACW, I’d imagine. :3
“It’s not gay when it’s with changeling.”
Ahem
“It’s just a channeling, ?” Cloned several times
