Way out to the fringe on this one. Gender Bender, Anthropomorphism, and Pokemon. Rule 34 true, but probably only for the 10 people on the internet who might be able to fap to this. I'll give it 3 stars though for art quality, at least its colored in and the subjects are recognizable.
Gotta agree with AerosM. The combination of fetishes makes this one bizarre clusterfuck (no pun intended). Plus, the whole transformation thing is pretty fringe, and in my opinion, just kinda weird. But, I gotta give it props, the artwork is good and consistent, the Charizard actually looks like a Charizard, the colors aren't eye-searingly bad, and there isn't any fixation on unnecessary details (well, besides the whole transforming thing). If it weren't for the weird subject matter, I would probably read this.
....by the gods, I've started reviewing porno comics on the internet. What the hell is becoming of my life?
