This post has content warnings for: tf kink musings so technically not 18+/NSFW - but none of these words are in the bible.

Neopets made me a furry, and well, Neopets has a lot of TF in it. You could be a shoyru one day, and then the next, you could be a jubjub, with only legs.
TF could encompass many things, from the Mental, to the physical, to the more esoteric means!
