She gives birth to your son

Even though your mother had gone through excruciating pain to deliver your son, she smiles when you bring the crying baby next to her. "Thank you," she says.

"No, thank you," you say, "for giving birth to the heir,"

Surprise colors her tired face. "What do you mean?"

"This is our prince, the one who will succeed me,"

"But what will the nobles, the people say?"

"They will be happy for the news. In fact, we will be having a celebration of our son's birth already planned,"

It takes a lot of plotting to let most nobles to accept the situation of your mother giving birth to your son. But nobles, despite their pompous and holier than thou attitude, are not noble in their behavior. While trying to criticize you, not few do the same, the least guilty engage fornicating with their own cousins. While some don't engage in sexual debauchery, they're involved something else, such as poisonous substance misuse and so on.

You and those nobles come to an agreement. As long as they shut up about you and their own perversions wouldn't affect the country, you will keep quiet about theirs.

The pious people are even easier to tackle. Even as they claim to serve the god, many of them have men, even young boys, serving them instead. Logically speaking, if **** is supposed to be prohibited because it's mentioned in the religious text, isn't homosexuality is supposed to be taboo as well? Why the double standard?

No one can answer that question.

Using this rational as impetus, you introduce laws legalizing them, and introducing a new one that prohibits **** sexual activities such as **** and underage sex, putting to **** all people engaging in such act, no matter whether they're religious or not.

As for the commoners, while there will always be dissenting voices, it is enough for you to tackle the majority. Most of the people will be more interested in their own lives and if you ensure that they are taken care of, and the nobles and religious figure don't go against you, they will be more than happy to accept whatever it is your doing.

It takes some time but despite the initial shock, the country's population manage to accept their first prince coming from the union of you and your mother the former queen. When your mother becomes pregnant again with your love child, the news is accepted with much fanfare, so much so when she delivers another son.

While she had two sons with your father, you and your mother have five beautiful children, two sons and three daughters. Despite that, you and your mother never marry; you're being fair by not marrying all the women you sired your children with.

As the King, your reign is one of peace and prosperity, as you use the knowledge and connections to better the country. Better farming methods are used, leading to more plentiful harvest, allowing you to tax them more and use that tax revenue to improve the farming method and so on. The result has been so successful that people started to use the expression 'blessed by the Queen' to refer to fertile lands though you fail to understand why since you, not the Queen, who work tirelessly to improve them.

Unknown to you and the nobles, however, you're given a moniker, 'Mother-fuck-King', even though no one dares to say it in front of you.
