"Breeders Anonymous" or "The Breeders Club"

"Human evolution has diverged once again, this time bringing forth a new class of humans known as the "Breeder" species. From birth until puberty they're indistinguishable from normal humans, but during puberty they undergo extreme changes. A female breeder will develop an exaggerated hourglass figure, large impossibly perky breasts that never seem to sag even without a bra, large yet proportional nipples with extreme levels of sensitivity, wide, round hips to make the birthing process not only simple but pleasurable as well, a plump, juicy rear that insures no matter how she's seated or laying down that any cum she takes in will funnel towards her womb, and of course a pussy that will never require outside lubrication and will perfectly conform to any sized cock that enters, while also containing up to 50 times the normal amount of nerve endings. A female breeder's body is in a constant state of ovulation and will never experience a "time of the month" or PMS. If she doesn't get bred the egg cells, which are constantly replenishing, will simply go back into rotation and await a later chance at fertilization. From the moment she hits puberty until the day she dies she will be as fertile as can be. Male breeders typically stand a better chance of blending in with regular humans, albeit with a few exceptions. Upon puberty a male breeder's cock and balls begin going through a metamorphosis, growing in length and girth. This process will typically last from puberty into the mid-twenties when they finally reach their maximum size. With sufficiently loose fitting clothing a male can hide his endowment easy enough, however they're also prone to excessive muscle growth. Where as a normal human male may need to spend years in the gym to reach body builder levels of bulk, a male breeder can achieve such a feat in mere weeks. It's believed the reasoning behind this is to help better insure the males virility, a healthy body means higher sperm production. Speaking of which, even without the improved physique a male breeder can produce copious quantities of semen with ease, some times even measuring in the gallons. Female breeders skin contains higher levels of collagen allowing them to stretch and take such large offerings, but for regular women it can be a bit...painful. One thing has been proven without a doubt though, anyone who has sex with a male breeder without proper protection WILL get pregnant. And any female breeder who doesn't take the needed precautions will face the same fate, and should a male and female breeder meet and mate? It will undoubtedly lead to multiples!"

Alright now that the background is out of the way let's get to the ideas! Basically this takes place in a world where human evolution has lead to the creation of Breeders. They're generally normal people, they just have INSANELY high sex drives and fertility rates. They often face persecution for their lifestyles but most just want to live a normal life and occasionally have some carnal fun. 2 possible ideas I had were for what are basically support groups, one is "Breeders Anonymous" a place where Breeder's meet to try and learn to live with their conditions, they strive to fight against their urges and live like normal people. The other is "The Breeder's Club" this is more of a college club where Breeders meet up to indulge in side urges free of scrutiny and judgement. I'm looking for someone willing to play as either a female Breeder or a normal girl looking to learn/experience what being a Breeder is all about. While I did lay out general guidelines for how a female breeder looks, there is plenty of room to play if you're not a fan of the sort of bimbo style I described. Nothing is set in stone.
