Warning: pedophilia and polygamy. Viserys is an old, horny pervert. He want to practice incest with his brother's daughters, daughter and granddaughters. Read at your own discretion.
Even as more and more members of the conspiracy were being rounded up, Viserys himself was having fun. The very day that his second wife lost her head, he bedded the Redwyne twins and then promptly married both in secret the very next morning. To say that their father was not pleased is an understatement, however, he was careful to not speak his outrage too loud in fear of losing his head. As for the court, they were disgusted! By this point in time, Viserys was 61 years old, making him 48 years older than his twin brides. Plus, despite all of Queen Alicent's numerous failings, she had still been his wife and to marry less than a day following her execution, people just found it a bit wrong.
To make matters even worse, it was soon learned by all that Viserys was bedding young ladies Peake, Fell, and Brax in addition to Lady Brax's unwed sister and Lord Rosby's young daughter, though the two unwed ladies, Viserys also soon took to wife. This meant he had four new Queen's and three young mistresses.
While there wasn't a single member of the court that truly supported the King's actions, there was a great hope among all of them that soon the succession crisis would be put to an end. With four young wives and his three young mistresses, surely one would soon birth a child. Yes, everyone craved the birth of a prince, but at this point, it was seen as for the King to even sire a princess to inherit after him would be better than nothing.
Viserys, still believing the words of Osfeth, insisted on performing the same shit filled ritual with all seven girls. However, since Viserys was having so much fun, he began sending summons out throughout the realm. He wanted more wives and mistresses. He also sought out treatments to ensure that he could get and maintain many erections each day so that he could seed each girl to better his chances of successfully breeding them.
Honestly, Viserys thought his council was far better at ruling than he'd ever be so he left them in charge of the realm. Fucking was a much better use of his time and talents anyways.
Within six months of Queen Alicent's execution, Viserys had married 35 noble girls whose ages ranged from 10-16 and had made them all his queens. He had also married and made his concubines 21 girls born to merchants and other higher ranked common status. These girls tended to be a bit younger and their ages ranged from 7-14. Viserys also took two separate ranks of mistresses. The first was his noble mistresses and these were the young wives, aged 14-18, of his Lords. He had 28 of these. The second group of mistresses, whom Viserys referred to as his whores, was the largest group and also had the youngest members with a total of 56 girls ranging between 5-12 years old. The youngest mistress was a pretty orphan waife who was found on the streets of King's Landing. They thought that she was about age five but Viserys absolutely loved having her suck his cock and balls. Due to her extreme youth, Viserys hadn't taken her maidenhead yet but he couldn't wait to see her in just a couple short years, heavily rounded with his bastard, on her knees sucking him off.
In total, Viserys took 56 new wives and had another 84 girls serving him sexually for a grand total of 140 sex partners for the king, or about 20 girls per day. Yes, Viserys had been very conscious of the Faith of the Seven and so ensured that he was adding to his harem girls at a rate of seven at a time. He figured by doing so, the Gods' would finally bless him with many children.
However, as the months passed, not a single girl's belly quickened despite how often he fucked each one. He sought tonics to improve his women's fertility from all over the world. He had tasters and healers check all food and beverage that they ate to ensure that none ingested anything that would prevent his seed from taking root. He had every girl who bled examined to see if their wombs were defective and yet nothing was ever found to be wrong.
Another year passed and still there were no heirs.
Then another year passed and Viserys finally reached out to his long estranged brother. Viserys begged Daemon to send him his daughters so that he could bed and wed them. Daemon replied with a harsh rejection.
Another year would pass and the 64 year old King was beyond desperate. He had even doubled the size of his harem, taking in girls from Essos, Dorne and even from among the Danes and yet not a single one ever conceived.
In his utter despair, Viserys sent guards to Mercia, where he had last seen his daughter, with instructions to steal her away. He knew his daughter was fertile so he planned to bed her and breed an heir or two upon her. However, during that time since he had left, Nyra and her family had moved and so the mission proved a failure.
Another three years would pass and still no heirs. By now, Viserys had heard that his daughter lived in Bebbanburg but he also knew that she was 40 and so was not likely to be able to birth more babes. Instead, this time, he decided to send a missive to her begging for her to send him one or more daughters to wed and bed. However, when Nyra received it, she burned the letter in disgust. There's no way she would let her sire fuck any of her children.
Viserys knew he was growing old and, despite all of the potions and tonics, Viserys just didn't have as much strength or energy as he used to. Yet he used all that he had to keep fucking wife after wife, mistress after mistress, whore after whore, day after day after day with the hope that eventually one would finally fall pregnant with his child.
During this time, Viserys did not do anything in his role as King and his council did 100% of the ruling and administration of the realm. The King simply did not have the energy to bother with affairs of the state after constantly fucking in his attempts to again be a father.
As for the council themselves, they struggled to decide on a logical succession for the King. The King's nearest kin had all very openly and loudly rejected him and a place in the line of succession. The King also only had one living child, despite his extremely vigorous attempts to sire more. Honestly, they all had come to the conclusion that their King was being punished by the Gods. He had murdered his first wife after raping and all but breeding her to death. Then he had abused his brother's loyalty and love to the point that he left to never return. The King had also allowed Ser Otto and his daughter to terrorize and plot against the Princess Rhaenyra to the point that they arranged for her to be raped and then permanently banished from Westeros. He had also taken for granted and then ruined his relationship with his cousin Rhaenys and her husband to the point where they also left. Viserys had destroyed the House of the Dragon under the "wise" council of Ser Otto to the point where Viserys himself was the only "dragon" left in Westeros.
