This is an idea i had with another, but it fizzled out due to real life issues. The basic premise is in this world, some ladies end up with superpowers based off of, well, Pokemon! They also end up as futanari, and grow in power by having sex with other 'Pokegirls'-kinda like Highlander but without decapitations and marginally less explosions.
What happens is up to us-i give you the basic premise and then we come up with the rest. I'm up for both serious stories and more lighthearted fare. Gimme a PM if this interests you!
