[DM4F] A mutation thousands of years ago caused human anatomy to change in order to prevent extinction (Please read description before you message)

I am the dom and the DM of this situation

Several hundred thousand years ago, a bottleneck event occurred. The outcome of that event caused a new kind of mutation to occur inside the female anatomy on a genetic level.

The mutation caused females to have the ability to get pregnant by two different people at the same time. This mutation also gives women two vaginas and two sets of ovaries, meaning that a woman can technically give birth twice. This mutation also gives the entire human population after the bottleneck near immunity to the harmful effects of incest and gives them the ability to get pregnant by animals.

This mutation caused the human population to explode. In the modern day, the population is close to 12 billion people. Because of this, human kind is more of a matriarchal structure but with an egalitarian system. What I mean is that most of the governments and high positions of power are female dominated but, under the law, they are treated the same regardless of their sex at birth.

Those without this mutation are often looked down upon as they can’t produce as many offspring as fast as everyone else and they are often not given the same opportunity or benefits as people with the mutation.

The downside of the mutation is that you get double periods and the menstrual cycle is more difficult to handle. Most women usually have both periods at the same time but some don’t.

On the opposite side of the equation, all men really got from that bottleneck was a higher sperm count and thicker cum. The average sperm count for a healthy male is about 500 million sperm per milliliter. The cum thickness was increased 250%, making it easier for women to get pregnant.

Anyways, that’s where you come in. A woman who just went to the doctor and you found out you have that exact mutation. With that, there’s a host of different paths. We can discuss it privately.

This is a pretty open idea and I would like to explore it

I am the DM in this situation, so I am not playing a singular character

My only limits are feet, weapons during sex, and bodily fluids (some blood and cum is ok)

Dm me if you’re interested and tell me your limits or you will be ignored
