Imagine being 10 and going off into the world with a similarly juvenile Buneary. Three years later you discover what masturbation is and you wake up to your Lopunny with her full female figure, ass that you could drown in, and nearly pussy greeting your morning wood.
Why the hell would any human mate with another female human when they could have a whole team of girls just ready to jump on their master's dick with a throw of the Poke Ball and a pull of the zipper?
Tell me, why haven't humans gone extinct yet when there is Poke puss like that everywhere?
