Hey Fireside,
Well FMG and Giantess work is what I excel at. Would this be the piece you're talking about?
Cluedog's Piece for me
Good luck making content! look forward to seeing whatever it is you come up with.
I totally forgot about my Bottled Sex series, the first half doesn't really feature transformations, but the second half has all sorts of gender fuckery. The jist is that I'm an assistant for a scientist that has created a way to bottle sexual urges. When the bottles are opened they release the energy for whoever is in the room, but when the genders of the sex recorded don't match up with the genders in the room, well that's where the fun starts for you guys.

I'll start when the TG fun starts.
Bottled Sex 06
Bottled Sex 07
Bottled Sex 08 - Not fully Gender, Futa, but I have a feeling some of you might like that
Bottled Sex 09 - Again, just futa.
