Harem World

This world wasn't so different from our own until various changes occurred that made it increasingly distant.

First, the male population began to decline periodically due to a deterioration of the Y chromosome. This resulted in men comprising only 10% of the population. They were so scarce that for every 10 people, only one was a man.

This led to women taking on a greater role in various areas such as politics, sports, and the arts. But over time, the population began to decline so much that the human race was on the brink of extinction.

Around this time, a second change occurred: when girls reached the age of 18, they experienced a kind of second puberty. Their breasts grew so large that 100 became the minimum cup size, and their buttocks became more fleshy and perky.

The changes weren't just physical; their clothing became shorter and more daring, as if they were rejecting normal clothing. It seemed that women had evolved to attract the few men who remained.

Unfortunately, there was a negative effect: once a month, women experienced strong sexual urges, which could last up to five days. During this period, the women fell prey to their most basic instincts, their sole goal being to have sex at all costs. The only way for them to control this phase of heat was to masturbate intensely so they wouldn't feel the urge to harm anyone.

And then the third change appeared. This one wasn't noticed immediately; it manifested itself gradually. Men ruefully found themselves surrounded by women; girls who had never been attracted to a particular boy would suddenly, for no apparent reason, throw themselves at that same boy.

It was as if men developed a mysterious power that attracted women. After much research, it was discovered that young men also went through certain changes shortly after turning 18.

It was more subtle than in the girls. Apparently, men had developed a small gland in their testicles. This gland was called Adonyx because of its characteristics. When fully developed, it produced almost odorless pheromones, except for some females.

It's not known for sure why some women are affected by certain pheromones; perhaps it's a genetic predisposition or a trait related to their aptitude. What is certain is that when a woman is compatible with a specific pheromone, she is sexually attracted to that man almost instantly.

As if a biological part of women were activated, they would be strongly aroused by that man without being able to do anything to avoid it. They would follow the scent with desperation and longing, and would do anything to be as close as possible. Until she could resist no longer, she would throw herself into a frenzy to have sex with that person, regardless of who it was or where they were. The most important thing for them would be the apartment, as it's the most vital thing.

In addition to pheromones, the Adonyx gland causes the penis to grow up to three times its normal size and increases the dependence on sex. The most alarming aspect was that continuous sexual activity induced a form of infatuation in women, though on a larger scale.

The analyses revealed that the sperm contained a potent substance, which only women perceived. This substance, combined with pheromones, created an addictive combination for the affected women.

This resulted in the women being transformed into submissive sexual partners for the limited number of available men, an adaptation that allowed the young men to attract as many women as possible. Those who had already undergone this transformation were called "Fuckers," the same name given to boys who had developed the Adonyx gland.

The transformation did not affect their intellect, but their personalities changed drastically to serve their partners. At least, that was the report from a renowned scientist before she succumbed to the pheromones of one of the patients she was testing, and she is now happily living with him.

Because of these drastic changes over the years, laws were passed to increase the population and regulate this new practice.

The harem system was created, allowing a man to have multiple wives without issue, as long as the women consented.

A system was also created that allowed young Adonyx men to have their own houses with their harems, where they could be more comfortable.

In a world like this, even the ugliest and most unpleasant young men had a chance. In this new world, any man has a desirable opportunity.
