>>51692601Because I'm an autist. While it does look pretty on the outside, I cant just stop here, I cant separate just visual from the actual function and structure. Female dolphin vaginal canal is very peculiar thing that is not very compatible with simple "flesh rod" penis after first few cm in. And yes, in general it is smaller in size and its canal is very tight as well. So on its own I dont think it would work very well for something like Vaporeon, consider possible broad spectrum of partners for female Vap to choose from.
Therefore, because she is still has some generic fish DNA and her overall body shape and skin composition is designed to be similar to seals/frogs, to ease flow of water around it, it would make sense if the external parts of her pussy would be similar or even 1:1 to the dolphin, with the exception being a bit bigger and softer so the hole can be looser. And internal parts similar to most mammals to accommodate typical mammal penis.
But again, I'm autist who find such details fascinating and hot and interesting to ponder about.
