The Three Headed Dragon

Summary:

Baelon and Aemon crawl into Vis' bed and talk to her, they wake up the next morning chaos ensures their father is fine with it and their mother is annoyed. They also attended a trial.

 

Or Baelon and Aemon have grown close to Vis and sometimes purely platonically sleep in her bed, Jaehaerys already knew and Alysanne loses her mind, Jaehaerys uses Alysanne's reaction as a way to get more heirs so he betroths Viserra to both her brothers.

Notes:

This is a crack fic.

I love Vaelon but recently I have began to wonder how Aemon/Vis/Baelon would be like. I think it would be an interesting dynamic.

(See the end of the work for more notes.)

Chapter 1: The heads of the dragon

Chapter Text

Viserra yelped as she felt someone kick her. She opened her eyes to see the blurry figures of her older brothers: Aemon and Baelon. “Move over” Baelon demanded.

“What?” Viserra asked opening her eyes a little more “What the hell do you want? I was bloody sleeping.”

“Bloody move” Aemon demanded “I have not slept a wink all this night because of your secret admirer, and it is all your fault.”

“Move you notorious bitch” Baelon added “This secret admirer of yours creeps me out.”

“He creeps you out?” Viserra chuckled “Then it seems we are in a whole lot of trouble then my beloved brother, he creeps me out as well which is why when the creeps identity is revealed I will not object to him being cut down by dark sister.”

“Or burnt by dragon fire” Aemon added “But seriously bitch, move over.”

Viserra rolled her eyes moving to the middle of the bed, her brothers were stubborn it was better to give in, in that case she may get some sleep. She did not have the energy to argue all night. Her brothers climbed in Baelon on the left, Aemon on the right, both of them kicking off their boots. She felt the blankets get pulled from her. “What have you done to upset Jocelyn now?”

“She is desperate to try for another baby, to fulfill her duty and give me an heir.” Aemon sighed placing his head on Viserra’s shoulder. “I do not care what father says Rhaenys is enough for me. Jocelyn and I…. I love her and I do not want to lose her. She had miscarried a lot and she nearly bleed out trying to give me a son. She wants to keep trying, I do not. Each time we lose a child, a part of us goes with them. I have mourned all the dead children I can. Joc, she will just not listen.” Viserra ran her hand up and down Aemon’s side.

“And you Baelon?” Viserra asked.

“I was lonely, also I can never find sleep the maids keep bothering me at all times of the night, but we all know they just want into my bed.” Baelon sighed Viserra chuckled loudly “What?”

“You both have the same problem essentially people want to fuck you yet you to not want to fuck them back!” Viserra laughed.

“Language” Aemon scolded.

“Not a child, Aemon.” Viserra rolled her eyes “I am a women grown at least in the eyes of our mother I am if it were up to her I would have been married off two years ago and would be carrying my second child. Beside if you do not want to hear such ‘foul’ language then do not use said foul language.”

“Vis had got you their brother.” Baelon chuckled pressing a kiss to Aemon’s lips.

Viserra rolled her eyes “Can you two love birds take it outside, preferably to Baelon’s chambers. Tis late, I am trying to rest.”

“Nope” Baelon responded pulling the blanket up “I am rather comfortable where I am.”

“Night” Aemon added.

“What? Aemon- Baelon what if someone sees. What the hell am I going to say. What if mother comes in. She will think me a temptress that-“ Viserra began.

“Seduced both her brother yeah, oh well” Aemon said “I do not know why she acts like Baelon, and I are fragile babies but leaves you to the wolves. There is a low chance of anyone seeing besides we are all in our clothes and there is no blood.”

“Mother will be inclined to listen to the truth.” Baelon added “But worst comes to worst you will likely either end betrothed to one of us or both of us, father had amended a law for more marriages to take place without abolishing the first.”

“In that case you do not have to marry Theomore Manderley.” Aemon said.

“Keep to your own sides you bastards.” Viserra grumbled “Oh and if anyone comes in you two will have the honour of explaining this. Good fucking night.” She leaned over Baelon and grabbed her robe, wrapping it around herself for decency sake, and curled up in her bed which was hard because even though the bed was massive her two brothers had decided to lay right next to her as if they did not have the whole rest of the bed. She wanted to try and convince them to leave again but she sighed giving up when she heard one of her brother’s snore, the bastard was already asleep.


They had not exactly lied to Viserra, Aemon did have a fight with Jocelyn, and he did have annoying maids bothering every second of the night but mostly they missed her. It was not the first time they were able to sneak their way her bed. She was comfort, she made them feel secure. They had done nothing more than kiss her forehead or hug her and yet she made woke something in them. It was hard to explain.

Viserra looked like a goddess curled up in her bed, her silver curls running past her waist, in a tight set of braids. She tried to stay away from them, but she kept moving back towards them a, because they were right next to her and it was hard to stay away from then and b because she was a dragon, drawn to the heat, they emitted heat.

He and Aemon had always been drawn together for as long as he could remember as soon as he could crawl he followed him around. Alyssa had known that it was more than platonic and supported it. They married for duty and had grown into love, the same happened with Jocelyn and Aemon. It was possible to love more than one person ar once.

Viserra was so much more than the vain little girl they thought she was. She was strong, kind, and competent. She snuck outside the red keep’s walls to read stories to the children in the orphanage. It warmed their hearts. When they actually took the time to get to know Vis they realised how amazing she was. Their feelings grew for her the more time they spent together. His feelings were more than brotherly.


Aemon woke up to Baelon groaning and Viserra was frantically moving around the room. The first thing he saw when he woke up were his three nephews staring down at him. They were not shocked though it was not as if they did not know both he and Baelon sometimes slept in their Aunt Viserra’s bed. The boys kept quite sometimes the boys would even come in and join them in the bed. Personally he was not extremely fond of that because the boys liked to curl up near Viserra, the bastards hogged his Vis and Baelon.

Baelon was fully dressed for the day, honestly he wondered where he got the clothes perhaps he used one of the secret tunnels, Baelon’s room was connected to both his and Viserra’s chambers.  He could vaguely see that his mother was in the room losing her mind.

“What are you doing?” Daemon asked him.

“What does it look like?” Aemon asked.

“Like you are hogging Aunty Vissy and Kepa” Aegon muttered. Just then the door opened revealing the King. The entire room went into a standstill.

“Ah, Baelon, Aemon I was wondering where the two of you disappeared to.” Jaehaerys chuckled.

“Why are you acting like this is okay!” Alysanne demanded “Viserra was in bed with her brothers! Rumours will spread around the keep.”

The man chuckled “Oh Aly I cannot count the number of times through the years that Viserra would crawl into Baelon or Aemon’s bed when she was younger. They are doing nothing wrong she is intact; her older brothers would not dishonour her. This has been going on for months, at least as far as I am aware, and I truly do not care as long as it keeps lordlings out of her bed.”

“But Jaehaerys-“ Alysanne started.

“Well then Baelon and Aemon will wed Viserra you know to prevent rumours from spreading.” Jaehaerys said. He had been planning on betrothing Saera to Aemon in the hope of new heirs, but Saera ran away, that betrothal could now fall to Viserra it was not like the betrothal to the Manderley’s could not be pushed back. It could fall to Viserra’s daughter should she have one or Gael. “Besides it is not as if it is unusual Targaryen siblings have weird relationships we shall settle at that.

Aemon climbed out of bed, “Fine” Aemon sighed “I knew this was a risk, we both did. She brings us comfort besides the children were not happy at the knowledge that there aunt was going away.”

“Oh I will say.” Baelon sighed.

“No Aunt Vissy cannot leave us.” Aegon whined wrapping his arms around Viserra’s leg.

“Then it is settled then” Jaehaerys said “It will help keep Baelon and Aemon’s relationship discreet they could even wed in the valyrian ceremony as well. You shall tell Jocelyn and your daughter.”

“Of course father.” Aemon sighed “Now why are you wondering around like a headless chicken Vis?”

“What?” Viserra gaped “The hearing of Henrik Redwyne is in an hour! You know for treason against the crown?”

Aemon looked at his parents and his brother who both nodded “Why didn’t you wake us up?”

“I just woke up myself as it turns out I was rather comfortable.” Viserra rolled her eyes “ I would have called for Daenora, but she will not be here till next week, and it was not like I could call for my maids, how could I explain why both of my elder brothers were just laying in my bed, basically spooning each other and me by extension? Then my beloved nephews entered and then mother and the father-“

“Would you calm the fuck down” Aemon ordered.

“How fucking dare you tell me what to do-“ Viserra started.

“Can you just calm down and turn around so I can lace up that stupid gown?” Baelon hissed and Viserra reluctantly obeyed.

“Do not blame me mother set the criteria for what I have to wear to the hearing.” Viserra hissed.

Jaehaerys chuckled as Baelon finished lacing up his sister’s gown. “All down sister if anything I think we have determined that I could be a fucking amazing maid.” Baelon replied causing the entire room to burst into laughter.


Baelon stood on Viserra’s left in a black tunic, a dark red leather doublet, and black leather pants, with dark sister on his belt and several daggers, he had several rings on his fingers, a gold band over his forehead and a black cape. Viserra stood in the middle of her brother, her silver curly locks were hanging down to her waist, rubies were in her hair, a jewelled ruby necklace, and bracelets with ruby rings. The top of her dress had a sparkly red top and a red flowing skirt. It had black dragons embroidered on the dress. The cape was black made out of the fur of a black wolf with red flower embroidered on it. Aemon was on her left with a black tunic, a bright red doublet with gold detailing, black leather pants and a dark red cape. He wore a gold band on his pale white hair shone.

“He looks cocky.” Viserra whispered.

“He best be careful he is getting on father’s nerves.” Aemon whispered back.

“I know right.” Baelon added giving Viserra’s hand a quick squeeze. “You will get used to it, after the wedding you will be expected to attend as a member of the royal family.”

“Do not look away, it shall only make it worse.” Aemon added.

“For crimes against the crown you shall lose your head,” Jaehaerys announced gesturing to Baelon. Baelon walked over pulling Dark sister from his belt.

“In the name of King Jaehaerys I of House Targaryen, King of the Andals, the Rhoynar, and the First Men, Lord of the Seven Kingdoms, and Protector of the Realm. I Prince Baelon of House Targaryen sentence to die.” Baelon said swinging dark sister and beheading Ser Redwyne. Out of the corner of his eye he saw Aemon give Viserra a comforting squeeze.

“Now that this is settled it is with great pleasure that I announce th betrothal of my second youngest child the Princess Viserra to both her elder brothers Princes Aemon and Baelon.” King Jaehaerys said “The wedding shall take place in a few moons.”

Viserra glanced at both her brothers, there was no going back.

Chapter 2

Summary:

Aemon and Jocelyn talk in the aftermath, later Viserra and Jocelyn talk

Chapter Text

“I will not let Rhaenys’ birthright be taken from her.” Aemon exclaimed as Jocelyn paced around the room “My father organised this Joc. I have heard you so let me explain.”

“Explain it then.” Jocelyn sighed as she sat opposite Aemon “Explain it.”

“Over the past year Baelon and I have grown close to Viserra, we began to get to know who she really was and not what our parents presented her to be.” Aemon sighed.

“She is so much more than what my siblings see.” Jocelyn nodded.

“Baelon and I discovered that we share many of the same interests as Vis, she loves hawking and hunting and dragon riding.” Aemon chuckled “I have also learnt that she has quite the political mind, ideas that could help House Targaryen prosper even more. Her ideas were brilliant, so I have presented them to the council as my own ideas, to which I have been praised for it.”

“Alright” Jocelyn nodded slightly.

“My beloved, Vis she is a dragon, a really caring girl. You know how we use to sneak out to get drunk when we were younger.”  Aemon said, Jocelyn smiled chuckling at the memory. “Well Viserra also sneaks out of the Red Keep as well but rather than getting drunk she spends most of her time down at the orphanages in Kings Landing reading to orphans. Viserra also helps out at the local homeless shelters helping prepare food. She was the one who discovered the child fighting pits….. oh god the child fighting pits,” Aemon shook his head.

“It is disgusting what those people did and it is disgusting that people would pay to watch those poor children fight each other.” Jocelyn muttered.

“Vis…. Vis has become Baelon and mine’s confident, she is who we go to for advice, whether it was everyday issues, issues with our children, issues with you or with each other she was who we went to. We feel comfortable with her….. tis not hard to go from loving someone to being in love with someone. We… we never acted on it of course. The most we ever did was curl up in her bed.” Aemon sighed.

“Ah so it is not Baelon’s chambers you have been in at night occasionally but the two of you have been in Viserra’s chambers. How does she feel about that?” Jocelyn asked.

“Vis, she was not happy at first well at all she grumbles when we wake her up. She tries to kick us out because though she does not mind us being in her bed, mostly because we are warm and she is a  dragon who likes the heat, she is worried about a servant or mother finding out because mother would see her as a  little temptress who seduced her two big brothers. Viserra did not really like the risk, but we continued to point out that worse comes to worse she would betrothed to one or both of us. Father has known for months or so he has claimed he just did nothing because it was innocent”.

“This funny you know Aemon; her grace sees the need to protect her two grown sons who one is in their late twenties while the other is in his early thirties rather than her own daughter who is only four and ten.” Jocelyn chuckled “I suppose her age is why the two of you never acted on your feelings. You could have had her if you wanted to, she is young and impressionable but no the two of you wanted it to be her choice,”

“Yes.” Aemon nodded “Jocelyn, I do not know how the line of inheritance shall work in the event that Vis has children, and we cannot tell who the father is, but I swear Jocelyn as long as I am alive Rhaenys is next in line to the throne after me, no son will change that not even if you bore me a son. Viserra has no ambition to have her children on the Iron Throne either she has seen how the throne has strained our parents’ relationship. The only ambition Vis has is the ambition to stay here within the Red Keep, she does not wish to be sent away abd married to a man older to our own father.”

“That seems fair enough” Jocelyn nodded “Rhaenys will be your heir no matter what?”

“I cannot speak for my father, your dear brother, Joc I cannot assure you that if I have a son with Viserra that my father will not name him my heir, but I can assure I will fight for Rhaenys. I want her to inherit the throne after me but my father…”

“Your father wishes for a male heir, a son to inherit.” Jocelyn sighed “I…. can still give you one… I know I can.”

“No, Joc I will not allow Rhaenys to lose her mother.” Aemon said firmly “The gods have decided that we will not be blessed with a son, we already have an amazing daughter, and she is everything I ever wanted in an heir.”

“If…. If you have a son and Rhaenys is disinherited as your heir, declared so by your father…. I want our grandchildren on the throne, Rhaenys’ line….” Jocelyn sighed.

“I shall have that done, in the event I have a son his and Rhaenys’ lines shall join.” Aemon nodded.

“Poor Viserra….” Jocelyn muttered “Your father will surely want a male heir out of her, there is little doubt of it. She…. She is still a child… she is younger than Daella was, and you know he will expect her to produce an heir immediately.” She wanted to resent the fact that Viserra’s future son would disinherit her daughter, but she could not it was not Viserra’s fault. It would be Jaehaerys’, Viserra was just a girl barely four and ten yet once she wed her brothers she would have the entire Targaryen dynasty on her shoulder or rather on her womb. She could no argue with her brother all she could do is ensure that Rhaenys’ child or rather grandchild ended up on the throne.


Viserra played with the rings on her fingers as she waited for Jocelyn to come, Jocelyn wanted to see her, and she was so bloody nervous. Jocelyn was her sister and now she was going to be her sister wife. Her sons would push Rhaenys’ down the line of succession. She knew her father too well. Their family nearly died out after having the throne for just over forty years.

Her Uncle Aegon was usurped by his uncle, her great uncle, Maegor the Cruel. Her father was a third son and yet he was the son who inherited the throne. Targaryens were dropping like flies, her father had six sons on his own and yet only three still lived.  Westeros was not like Old Valyria it was an incredibly sexist place, a women in power was considered a terrible thing. Their dynasty was young people still were not overly fond of their family traditions. The lords would not accept a women on the throne, they would throw the realm into war. Their family must be protected. She would no lie and say her father was a great man and father, but he was a good king at the expense of their family. Her father wanted to protect their house…. He just did not know the right way to go about it.

Viserra sipped her tea as she waited, eventually the door opened revealing her good sister. “Lady Jocelyn.” She smiled.

“Viserra” Jocelyn responded “I think it is time we talk about the recent developments within our family. If I am to understand everything correctly you do not want this?”

“All I want is to be near my family…. I do not want to be sent off to the North to marry a man older than my own father. The Queen is trying to punish me for the actions of my sister. I am more than Saera’s shadow. I am my own person.”

“That you are.” Jocelyn agreed “If you have sons they shall displace Rhaenys in the line of succession.”

“I never wanted that…. would- would that be any sons or the ones we are certain are Aemon’s? It may be hard to tell whose is?” Viserra muttered If she were to be them in quick succession or at the same time it may be hard to tell which child belonged to which of her brothers.

“Any sons likely,” Jocelyn sighed “Aemon sees Baelon sons as his and Jaehaerys knows that hell knowing my brother he may only make you lay with Aemon until you are with child. We both agree that Rhaenys should end up on the throne, but my brother will not allow that to happen, so I am here to propose a deal. In the event you have a son, and he is declared heir I propose that he is betrothed to a daughter of Rhaenys’ so that their lines may join.”

Jocelyn smiled at her “I shall think about it I know that betrothals are necessary yes, but it feels strange arranging the betrothal of children who have yet to be conceive. I understand that marrying is part of our duty, but I wish for my children to have some say in their marriages, I was almost married off to a man older than my own father, a man who has a daughter of age with my mother. I shall consider it of that I promise you, but I cannot in good faith agree to a betrothal of children who are long away from being conceived.” Viserra shook her head “Not…. Not after what nearly happened to me. I am sorry Jocelyn I do not mean to offend you but-“

Jocelyn had to say she was a little disappointed, but she knew Viserra was not doing this to spite her, it was disappointing but understandable. “Of course I am glad that you shall consider it and I understand your reluctance to betroth two unconceived children. After the match you nearly had it is more than understandable.”

“Thank you.” Viserra sighed “I never meant for this to happen, it was innocent Baelon and Aemon sleeping in my bed, we were all fully clothed and-“

“Aemon has already explained it Viserra I do not blame you I will be honest I want to blame you, but I cannot. It was innocent three siblings sharing a bed, when we were younger Alyssa, Baelon, Aemon and I would all share a bed. It is more than comfort is it not?”

“Not entirely, I am a dragon I love the heat and my brothers well they just radiate heat. I…. I have an admirer and he creeps Baelon and Aemon out with the gifts and letters he has sent me…. he creeps me out…. I am scared. I feel safer when my friends guard my doors. I feel safer when Baelon and Aemon lay beside me. They are both strong warriors bonded with dragons. They have strong bonds with their dragons Caraxes and Vhagar can feel their distress. I feel so much safer when they are there.”

“You have an admirer?” Jocelyn asked Viserra nodded. What stuck out to her was not only was Viserra scared but Aemon and Baelon were creeped out that meant it had to be bad. “Do you still have some of those letters or gifts?” Viserra nodded “Well it seems I best have a look.”

Chapter 3

Summary:

Jocelyn curses Aemon for his foolishness, Viserra thinks about her upcoming marriage and talks with Rhaenys

Chapter Text

She inwardly cursed her dim-witted husband;  he should have brought the matter to the king moons ago. No wonder Viserra felt safer when she was around her brothers, those letters and ‘gifts’ were creepy at best. Viserra’s guards had now been doubled and any gift sent to her room had to be seen by the King first. Her brother had been furious when he found out that someone in his castle had been making his daughter feel unsafe in her own home. Her elder brother yelled at his eldest two sons for their incompetence and for keeping this ‘admirer’, more like stalker in her opinion, from him.

Viserra was understandably freaked out so Jaehaerys decided it would be best to have Viserra trained with a dagger by her brothers, in case the creep tried something while she was alone.

Her sister had been distraught knowing that some creep was making her daughter feel alone in her own home. She had spent the last few days continuously apologising to Viserra for the betrothal to old Theomore Manderley though she did not think Alysanne was actually sorry for the betrothal. Alysanne had finally came to the conclusion that Viserra’s betrothal to Aemon and Baelon was not going to magically disappear like she hoped. Jaehaerys was holding firm on his decision and Jaehaerys was the King, no one dared to question the King.

Alysanne knew that she was not getting rid of Viserra, so she was trying to straighten things outs between them although Viserra was not very delighted at her mother’s smothering attention. Viserra preferred to spend time with her and her brothers rather than her mother it seemed that Alysanne basically ignoring her second youngest child came back to bit her in the arse and she could not blame Viserra.

She had seen her good sister try for years and years to spend time with her mother and father. She watched as Viserra was constantly brushed off and forgotten. She had watched as Viserra and Saera were the only person in the keep that the other could turn to before Saera ran away. She had watched as Viserra cared for the children of the Red Keep.

Jaehaerys quickly became more welcoming to his daughter when he found out the brilliant ideas that Aemon presented were actually hers. He even welcomed her to the council as an advisor. She was kind of happy about it if Jaehaerys had seen Viserra’s worth as an advisor on his council then perhaps he would see Rhaenys’ worth as an heir to the Iron Throne.


Viserra curled up in between her brothers. The wedding was getting closer and closer and yet no one was any closer to finding out just who was sending those creepy letters. What brought her comfort though was knowing that her brothers were at her side and her door was well guarded by people she trusted.

She was incredibly nervous knowing that that creep was still out there made her feel sick to her stomach. Her betrothal to Lord Manderley was over but now she was to be married to her brothers, much sooner than she was going to be sent North to marry the Lord of White Harbour. Lord Manderley had been married five previous times and had fourteen children from the five marriages, on top of ten grandchildren and twenty great grandchildren. At least by marrying her brothers she would only have three stepsons and one stepdaughter between the two of them and a sister wife.

At least she would be able to stay in the Red Keep. She would not have to leave her family; she would be here to protect Gael and hopefully Aemma from her parents. Someone had to because none of them fought to stop her betrothal to Lord Manderley and no one fought to stop her betrothals to her brothers, other than her mother who only fought it because she wished to sell her as a broodmare to the Manderley’s. No one fought for Daella, her simple minded and fragile sister and it ended up in Daella dying birthing a child sooner than her body was prepared for.

She would fight for her sister; she would fight for her nieces and if she was ever blessed with daughters she would sure as hell fight for them even if it was the last thing she did.

She knew her father would expect her to bear her first child nine moons after her wedding. She knew her father was hoping for a son, Aemon’s son, to succeed Aemon. A male grandchild sired by his precious heir.

She wanted children that was true but was it stupid to want them born the same way that most of her siblings were born? To be born out of love rather than duty? As a women her only duty was to birth as many heirs as possible for her husband and in turn House Targaryen. Perfect silver haired, purple eyed boys.

The only good thing about marrying her brothers would she was able to claim a dragon, Dreamfyre, as she always wished to. It felt amazing to fly in the sky, to be one with the clouds. The bond she felt with Dreamfyre was amazing. To be one with a dragon was incredible. It was an experience that not many alive could claim to have experienced.

Her siblings were her safe haven, her protectors she felt safer when they were around her. Both Aemon and Baelon would treat her right, she knew that she had watched them be great husbands and attentive fathers for years.

This could work, they could make this work. They had to be a unit for the sake of her niece and nephews.


“I still cannot believe you are marrying my dad.” Rhaenys grumbled “You are going to have my siblings….”

“I am less thrilled than you are.” Viserra chuckled “My father wants more heirs for House Targaryen and when your grandmother found out that your father and uncle had been innocently sleeping in my bed he had an excuse to betroth us. Baelon was lonely in his bed, your father had a fight with your mother, and I was scared because of my ‘admirer’. I think that your father and Uncle were just making excuses to sleep in my bed because they knew of my ‘admirer’, and it creeped them out as well. They wanted to keep me safe.”

“If you have a son he will displace me as my father’s heir.” Rhaenys said.

“I do not want that and neither does your father, but you know what my father is like Rhae. The seven hells would freeze over before he allowed a women on the throne, but I am hoping that with being on his small council due to my brilliant ideas, his words not mine, that I will be able to make him and the men of the council she us women as capable of running the seven kingdoms.” Viserra sighed “Have you thought about seeing if you could be the cupbearer? It would give you an excuse to be in the small council room and perhaps interject ideas every now and then establishing yourself?”

That was not a bad idea actually the sooner she established herself as a capable heir, the more time she had to make connections the better. If her aunt could establish her worth on the small council then perhaps people would be more open to her being heir.

“If I was you I would marry Viserys.” Viserra said.

“What?” Rhaenys asked “Why would you have me marry Viserys?”

“It could take me awhile to conceive and it could take me a while to have a son. I hate to say this Rhaenys but if something happened to you father while my father was alive, and he had no son-“ Viserra began.

“Uncle Baelon would be heir and in turn Viserys would be his heir.” Rhaenys finished “I would still be queen in that event.”

“Viserys is my beloved nephew, but he is weak, a pushover you could rule through him in that case.” Viserra added “In that my father has you passed over as Aemon’s heir well when looking for brides who would be a better option for a bride then the daughter of two Targaryens?”

“My grandson would still end up on the Iron Throne.” Rhaenys said.

“You mother wanted to betroth my future son to your daughter, but I will not betroth two unborn children however they could be raised to have a fondness for each other Rhae then the objection to the betrothal would be far less, perhaps they could even love each other.” Viserra replied “I adore you niece so I shall tell you this now if my father has his way you will never end up on the throne. The Lords of Westeros will not support a women on the throne at the moment but if you establish yourself now. If you let them see how capable you are you could have their support.”

“I could.” Rhaenys agreed.

“You are a bright young women Rhaenys. You are more than capable of being your father’s heir. You are the blood of the dragon.” Viserra said “You are a descendant of Aegon the conqueror but more importantly you are descended from Daenys the Dreamer the women who made us royalty. Visenya and Rhaenys sat on the Iron Throne hearing petitions and ruling just like Aegon did for some reason that stopped. Go around the realm Rhaenys perhaps on a procession. Prove you are a worthy heir while there is no son to compete with. Prove yourself to my father. The Lords of Westeros are sheep you are a dragon so be a dragon.”

“Be a dragon” Rhaenys said “Perhaps it is time I do exactly that.”

Notes:

To clarify some things:
1. This takes place in 86 AC

2. Nothing sexaul had occurred between Vis and her brothers

3. Aemon and Baelon have been in a secret relationship for years.

4. Jocelyn is alright with Baelon/Aemon because Aemon also loves her.

5. The reason Jaehaerys is alright with it is because nothing sexaul took place, it prevented other men from being in Viserra's bed, and worse come to worse he had an excuse to force Baelon to remarry and Aemon to take a second wife in hope of a male heir.

6. Baelon and Aemon have some feelings for Vis but have not acted on it.
