This is a continuation of a story from the Cum Addiction storyline, along the "Your Daughter" path, which I wrote.

I would suggest reading that story, but if you do not, here is a quick recap.

John was a doctor treating a disease commonly called by the name "cum addiction disease". The disease made life difficult for those with it, as their bodies became for a protein found in abundance in human male semen.

As the disease progressed, the women afflicted with it would become more and more for it, need more and more to provide what they needed, and would experience an escalating state of arousal during times without treatment, which presented as nymphomania or sex addiction.

At first, treatment was limited to oral delivery, with a large group of vetted donors delivering to a cup, but as symptoms and stages progressed, direct oral became needed and anal delivery became require to prevent women from progressing past the stage of the disease they were in.

The disease only impacted women, and tended to primarily effect young women, starting around their 18th birthday.

Our main characters John and Kira are father and daughter, and when Kira became sick her father agreed to be her donor to spare his daughter the shame of having strange men cum in her mouth, or if she progressed in her ass.

At first, John only delivered in his daughter's mouth, but this did not last very long. Their emotions and sexual attraction soon got the better of them. Kira was one of the young women who advanced quickly, and who orgasmed when she was given a dose.

The two of them ended up having sex, and when they orgasmed together, a bond was formed between them they did not foresee, and an actual change began in their bodies, in their DNA.

They ended up combining to form a new strand of the disease that caused the patient to produce more of the protein rather than having the disease destroy it. They also started to see other physical changes.

They both noticed better vision, better hearing, and a high degree of empathy between father and daughter, and also an increased degree of empathy between them and others. They got to where they could feel the emotions of other people around them, and they did not know why.

The father, John, ended up serving as a donor for women who were of political and cultural importance who were in danger of or of unsustainable levels of the disease. They found that his semen was too powerful for any known contraception, but that a woman he impregnated was at least for the term of pregnancy immune to the disease, it bought women time.

John and his daughter Kira ended up having three kids, and their kids provided the DNA material and stem cells which were used to develop the cure. While the cure was developed, medical professionals inseminated thousands of women with John's semen to confer a temporary cure, and he had direct unprotected sex with the political and cultural elite, as it was a more reliable method.

In time John having sex with other women was not needed, and father and daughter desired to only be with each other. As their children grew, John and Kira found that they were not aging at all. John still looked 36, and perhaps even younger.

Kira looked like she did the first time she had sex with her dad, one day after her eighteenth birthday.

Their kids however did age and did not stop at eighteen. It was asked if John would impregnate his daughters when they were of age, and he and Kira declined. And they watched their kids grow old and die.

This story picks up around 100 years after the events of the ending of my last story, as John and his daughter Kira have kept a low profile to try to avoid notice as they don't age.

Our story will continue now.
