There's a turnaround

Two long months passed with Sophie and Sarah having adjusted to their new routines when Dr Lewis asked Sarah to take Sophie with her to work. So she did, and once again they found themselves in front of the doctor.

"Goodnight. I have called you here because I believe it is my duty to inform you of what we have discovered so far based on the samples collected from you." Dr Lewis said

"Did you find out if it's safe?" Sarah asked

"As far as we know it's not a problem, at least not as long as you take care of it. You can rest assured, as I said before, only Sophie's blood and Sarah's blood showed an unknown substance, which we've been studying, and we can say that it doesn't cause any health problems, but we found that it can change each other's lives forever ." Dr Lewis

"How would this change in the lives of others?" Sophie asked

"The unknown substance, which has the provisional name of hermaterone, alters the functioning of genes related with the person's sex, causing a change in them. I don't know how much you know about this, but an anomaly is very common that causes an extra chromosome referring to the opposite sex to be present in people's DNA, and this extra chromosome is not activated and does not make the slightest difference in people's lives. It turns out that it is estimated that 40 to 50 percent of the world's population have this inactive gene in their DNA." Dr Lewis said

Taking some papers out of the drawer, the Doctor handed them to Sarah and Sophie to look through.

"It turns out that Sarah was the first documented case where this gene was activated and, according to research, and with the help of some volunteers who served as guinea pigs, we have an idea of ​​what happens, although we need more studies. to confirm. The thing that is certain is that anyone who has the extra gene and gets your cum inside him even once will also have his extra inactive gene inactivated and within a few weeks his entire reproductive system is switched to that of the opposite sex." Dr Lewis said

"You mean you gave my cum to some women and now they have a dick too?" Sarah asked

"Not only that, but men with this gene who received it now have a vagina, uterus and eggs, they even menstruate and are fertile." Dr Lewis said

"So why has Tom fully changed into a woman instead of just between his legs, and now Sophie is here beside me?" Sarah asked

"It's because he doesn't have the extra gene. It turns out that hemathalin affects people with normal genes, altering their understanding by the body, making them completely change sex. The other difference is that in these cases the change does not occur with a single dose of your semen, but constant contact as you would expect in someone who has a long-lasting relationship like the two of you. Eve herself, she is still 100% because she only swallowed her semen once, but if she did it continuously like her husband, by now at the very least she would be in the process of becoming a man, if she hadn't already fully converted." Dr Lewis said

The explanation was a little complicated for Sophie to understand, but it was only now that she was getting an idea of ​​the shift in reality brought about by her wish to allow her wife to spontaneously grow a dick and transform her from the man she was into a woman.

"If the studies are going to go deeper I think you're going to need more of my semen, aren't you?" Sarah said

"Not necessarily. Volunteers of those who have undergone genital swap also produce hermatoline. So much so that now we recommend that if they have a sexual partner, to make them aware of the risk, because now with them it is no longer just an unexpected pregnancy that can happen." Dr Lewis said

Later, on the way home, Sarah said "Now we finally know what happened to me. And thinking at this point, now that you're 100% a woman I can't keep thinking of you as my husband, I'm going to start referring to you as my wife."

"OK. I already work at home and do all the housework since I was a man, nothing more than natural. But then I have to call you my husband?" Sophie said

"No. I know that if we put it into practice I am the man of the family, so much so that if we still have children, I will be the father. It's just that I still want to be seen as a woman despite everything, I still want you to call me your wife." Sarah said

Sophie agreed, even though she realized that she couldn't think of Sarah as the husband in the relationship anymore.

Unknown to anyone until then, this resolution caused a reaction in the magic coin that Sophie had hidden at home, which disappeared from its hiding place and reappeared inside Sarah's bag, where it would be easily found by her. There was also a change in the coin, which on the side that showed Sarah's face, now showed Sophie's.

Some time later, Sarah opens the bag and while digging through it, she finds the strange coin.
