Brienne watched closely as Jaime escorted the prisoner into the room.
Today, an alpha stood on trial for the murder of several omegas in King's Landing. Brienne would have preferred not to have her own omega near the sick bastard, but she knew he was more than capable of defending himself and Tywin Lannister would never let anything happen to his golden son, anyway.
Ever since Jaime presented at the young age of sixteen, King Tywin had made it his mission to ensure that all omegas were protected. Nobody would harm a hair on one of their heads, especially not the prince of Westeros. The Omega Protection Acts were soon passed and those who violated them would suffer severe consequences.
That is what led to the current trial of an alpha who repeatedly broke those laws. Tywin wanted to immediately sentence him to death but was advised to give a fair trial, so here they were.
Jaime and the prisoner finally reached the front of the room where he guided the alpha onto the stand and then left his side to take his seat beside Cersei, his twin sister. The female alpha greeted her brother with a warm smile.
Tywin stood from the throne to address the court.
"Today, we've gathered to pass judgement on this-"
He paused as a strong, overwhelming scent suddenly spread across the room. An omega was in preheat. And not just any omega. Brienne knew that scent very well.
She jumped up and quickly made her way across the room as the alphas present started to growl and sniff for the source of that alluring smell.
The alpha prisoner suddenly snarled and his head snapped towards Jaime who was frozen in his chair.
Tywin, who was unaffected by his son's pheromones quickly ran to him. Both he and Brienne arrived at the same time and dragged the dazed looking Jaime out of the room.
"Alpha... Need... " Jaime whimpered as they guided him towards the private wing of the Red Keep.
"Don't worry, my love. I'll take good care of you." Brienne soothed, kissing his forehead gently.
"Lady Brienne, why is my son going into an irregular heat? This is the second time in two months." Tywin questioned as they approached Jaime and Brienne's bedchamber.
"I'm not sure, your grace, but I'll take care of it." she answered.
"You better. I would hate to find out that I trusted the wrong alpha with Jaime. See to it that this doesn't happen again." Tywin said.
Brienne froze at the king's subtle threat. She wouldn't be able to live with herself if she had to watch some other alpha claim Jaime as theirs. The omega knight belonged to her and she would do everything in he power to make sure it remained that way. They both loved each other too much to be separated.
Jaime whined quietly as he was hit with another wave of blistering pain. The heat was intensifying much quicker than usual. Tywin frowned and gently layed his son down on the bed.
"What have you been doing to satisfy his heats?" the monarch asked Brienne, stroking a hand through Jaime's golden hair. Jaime quieted down, recognizing his father's comforting scent through the haze of his heat.
Brienne hesitated to answer, not feeling eager to share such explicit details with her good father.
"Answer me!" Tywin snapped. Usually, the alpha king was much more composed, but right now he was concerned for his vulnerable child.
"Jaime prefers not to be penetrated, your grace. I honor that request even during his heats." Brienne told him reluctantly.
"Jaime is an omega who doesn't know what's good for him. It's your job as his alpha to make sure he gets what he needs."
"He's gotten through all of his heats without it so far. I don't think he needs it."
"Every omega needs it!" he shouted. "You will knot my son and put an end to this nonsense! If he goes into another irregular heat, I will find a more suitable alpha."
"Father, no." Jaime croaked.
"Hush, Jaime. You know better than to interrupt when two alphas are talking." Tywin said gently but firmly.
"I'm sorry, your grace. I'll make sure he gets everything he needs this time." Brienne conceded, not willing to risk losing her mate.
Jaime opened his mouth to protest, but snapped it shut when Tywin shot him a stern look.
As the king stood up to finally leave the room, he stopped to speak to Jaime once more.
"I suggest you behave for your alpha, son. Because if you don't receive a knot this heat, I will watch to make sure you are knotted in the next one." he threatened before stepping out of the bedchamber.
The tradition of the family patriarch witnessing the mating of their omega offspring wasn't common in modern days, but it was still legal. Any father has the right to ensure that their child's well-being is being prioritized by their mate by any means necessary. Tywin had refrained from acting on this tradition because he knew how traumatizing it would be for Jaime, but now he was left with no choice. It was his job to make sure his son had a worthy alpha.
Brienne climbed into the bed and pulled Jaime to lay on her chest.
"Alpha, you promised me that I would never be fucked unless I asked for it." he whispered, cheeks turning red.
"I know Jaime, and I'm sorry. But we can't defy your father. You know he doesn't make idle threats." she replied.
"I-I'll talk to him. I'll convince him that I don't really need it. I've been doing just fine without ever being knotted." the omega said unconvincingly.
"You know there's no convincing Tywin. Besides, he's right. You can't keep having these irregular heats." Brienne responded.
"But, alpha-"
"Enough, my love. Do not argue with me." she commanded, firmly grabbing his chin.
Jaime wanted to protest, but he was hit with another wave of heat. The Omega knight whimpered and burrowed his head into his mate's chest.
Brienne sighed and rolled him over. She would let him have one last night without penetration. Tomorrow, he would be knotted.
Female alphas did not have knots. This is part of the reason why they are rarely deemed as acceptable mates (the other just being misogyny) and most don't even end up with an omega.
So, Brienne of Tarth was very surprised when King Tywin Lannister gave her his blessing to claim his only omegan offspring.
Of course, Tywin never would have approved of the match if there wasn't a way for Brienne to satisfy Jaime during his heats.
There was a technology created that gave female alphas the ability to knot their omega partners. It was a golden cock that was attached to a harness. The only setback was that this tool was very expensive and therefore, lowborn alpha women did not have access to it. Even some noble families couldn't afford the ridiculous price.
But, as the ruler of the seven kingdoms, Tywin could acquire whatever he needed or desired. So, he had a knotting harness personally made just for his son's mate.
Brienne had never bothered to use it until now.
"Alpha. It's...it's so big." Jaime groaned as she slowly rocked the golden cock in and out of his wet entrance.
The omega looked beautiful laying on his back with his muscular legs spread to reveal his leaking dick and stretched hole. He fisted the sheets as Brienne moved inside of him, stroking his walls and triggering so many sensations that Jaime never knew he could feel.
It felt... good.
"You're being so good for me, darling. Just lay back and take what alpha gives you." she praised, speeding up the rocking of her hips.
Her sweet omega was clearly overwhelmed by the pleasure. His eyes fluttered every few seconds and every thrust punched out a high pitched whine that Brienne would've mistaken for a sound of pain if she didn't know him so well.
"Yes, alpha. Yes, alpha. Yes, alpha." Jaime mewled as Brienne striked his prostate. His noises were getting more and more desperate as she continued to fuck him.
Each glide into Jaime's ass was smoother than the last, his slick lubricating the large golden cock that was filling him up so well.
Sensing that her mate was close, Brienne grabbed his rock hard shaft and began to stroke it quickly. Jaime moaned loudly and clenched his fists tighter around the bedsheets.
"Be a good boy and cum for me, gorgeous." she said sweetly.
"Oh, alpha. It feels so good. Don't stop" Jaime babbled, grinding into Brienne's tight grip.
He looked so out of it. Brienne had never seen her omega in such a state of dazed pleasure. She wished she had fucked Jaime sooner.
"That's it, my beautiful boy. Alpha won't stop. Go ahead and cum." she said, putting more force into the pounding of her hips.
With that, Jaime finally orgasmed. He whimpered pathetically as he released all over his own stomach.
Brienne fucked him through it and then started to slow down. Then, she carefully pushed the fake knot into Jaime's spent hole. The omega groaned quietly as he was stretched even wider.
As soon as the knot popped inside, the omega passed out, his heat finally satisfied.
Brienne adjusted them so that she could spoon him from behind while waiting for the golden knot to shrink down. She placed a gentle kiss on his left temple.
"Sweet dreams, my love."
Usually after an Omega is knotted, they do not go into heat for at least another three months.
So, when Jaime's next heat started just a week after the last one, Tywin was both concerned for his son's health and furious at Brienne for letting it get to this point.
"I thought I told you to give my son what he needed, Lady Brienne." Tywin seethed.
They were seated across from each other in the king's study, Tywin having summoned her as soon as he noticed the spreading of Jaime's pheromones.
"I did exactly as you asked, your grace." Brienne told him nervously.
"Then why is Jaime in heat again? Do I need to find someone else to do the job?"
"No! No, King Tywin. You know Jaime wouldn't like that."
Tywin mentally took note of the fact that Brienne showed more concern about his son's happiness then her own.
"I think you should know by now that I care much more about Jaime's wellbeing than his desires. If I had given him everything he ever wanted, the omega wouldn't have lived long enough to even meet you."
Suddenly, there was a timid knock on the door.
"Enter." Tywin said.
Grand Maester Pycelle entered the study.
"Your grace. Lady Brienne. I believe I've found the cause of Ser Jaime's condition." he started.
Brienne perked up.
"Well, what is it?" she asked impatiently.
"You said that up until last week, Jaime had never been penetrated during his heats." Pycelle continued.
"That is correct."
"Well, omegas need a knot in order to tame their heat cycles. Since the prince had gone his whole life without receiving one, his instincts basically malfunctioned, hence the frequent irregular heats." the maester explained.
"That still doesn't explain why the knotting didn't work last week." Brienne said, confused.
"Well, my theory is that your mate's heat cycles are so out of whack that only a real knot would truly satisfy them." he told her.
Tywin glared at Brienne.
"So, what you're telling me, Maester Pycelle, is that Brienne's own incompetence has put my son's health at risk." the king said menacingly.
Brienne flinched at the harsh words, but they were true. It was her job to take care of Jaime, and she should not have conceded so easily when he requested not to be fucked through any of his heats. Now she might lose him for good.
"Please forgive me, your grace. I never meant to cause Jaime any harm. Just allow me to make things right." she pleaded. It was rare for an alpha to beg, but Brienne couldn't bare the thought of someone else claiming Jaime as their own.
The golden prince belonged to her.
"Unless you can grow a cock beneath those breeches, I don't think it's very possible for you to make things right, Alpha Brienne." Tywin replied.
The words flew out before Brienne could even think it through.
"I'll find someone!"
Both Tywin and Pycelle stared at her, dumbfounded.
"Find someone?" the monarch questioned in disbelief.
"I'll find an alpha to give Jaime a real knot. Just please don't take him from me." Brienne appeased.
"Jaime is a Lannister. I will knot have just anyone breeding my son." Tywin grumbled.
"It won't be just anyone. You know me, good father. I would never expose my omega to an untrustworthy alpha." she appeased.
They sat in silence for a few moments as the alpha king considered her suggestion.
Finally...
"You have until tomorrow morning. Jaime's heat worsens by the day." Tywin said.
Brienne smiled and thanked the other alpha.
That night, Brienne fucked Jaime again. She wanted to spend another night with her sweet omega before another alpha came in the next day to knot him.
... She also didn't have the courage to tell Jaime about her plans while he was fully lucid.
"Baby... I have a surprise for you." Brienne started as Jaime bounced on her fake cock.
The omega slowed down a bit and opened his eyes, gazing dazedly at his alpha as he continued to move his hips.
"S-surprise?" he slurred.
Brienne smiled at her beautiful mate.
"Yes, my love. It will make you feel so good."
Jaime tilted his head.
"But alpha already makes me feel good."
The alpha felt her heart swell at those words. Her omega was so sweet.
"I know, honey, but wouldn't a real knot make you feel better?"
Jaime paused.
"You mean... you want another alpha to fuck me?" he asked uneasily.
Brienne sat up and wrapped her arms around his waist.
"It will be someone you know, and I'll be right here the whole time, darling." she explained.
"No."
"Jaime..." Brienne sighed.
"No!" he shouted.
"This is for your own good. The golden knot doesn't satisfy your heats-"
"It satisfies me just fine-" Jaime interrupted.
"-and you're father will pair you with another alpha if we don't do this." she finished.
"Fuck my father!"
"You can say that all you want, but you know Tywin always gets his way."
Jaime frowned, hating the fact that she was right. His whole life, his father had gone to great lengths to make sure he was taken care of. He didn't care if Jaime was miserable as long as he was physically safe.
Well... Tywin's definition of safe.
"You would have me give my body to someone else unwillingly?" he asked in despair.
"Oh, Jaime. I wish there were another way." Brienne answered guiltily.
The next morning, Brienne gently bathed and prepared Jaime. She cuddled with her pouting omega in the bed until there was a knock on the door.
"Alpha Brienne, your guest has arrived." the servant announced on the other side.
Brienne felt Jaime tense up against her and he let out a faint, distressed whimper.
"Let him in." she called out, tightening her arms around her mate.
The chamber door opened and Bronn of the Blackwater entered the room with a big smirk on his face.
"Greetings, my lady. Morning, princess." he greeted smugly.
Jaime looked up, shocked to hear the voice of his friend.
"Y-you chose him?!"
"Ouch." Bronn said, bringing a hand up to his chest. "You should be happy to see me."
"Why would I be happy to see you?" Jaime retorted.
Brienne gave him a reprimanding smack on the ass.
"That's enough, Jaime." she scolded gently. "Bronn, let's get this over with."
"No complaints from me." Bronn responded.
Brienne turned Jaime onto his back, pulled him to lay between her legs, and gripped his muscular thighs to spread them open for the other alpha.
Jaime whined in embarrassment as his slick hole was exposed to their friend who he never imagined would be fucking him through one of his heats.
Bronn wasted no time stripping off his clothes and climbing onto the bed. He crawled between the Omega's legs and immediately pushed in.
"Ah!" Jaime cried as he was abruptly filled.
Brienne slapped Bronn's shoulder.
"Be careful with my mate. He is not used to penetration. I'll kill you if there's tearing." she snapped at him.
"Then I'll die a happy man." Bronn groaned out, grinding into Jaime's wet channel.
The omega knight whined at the sensation and grabbed Brienne's left hand. His alpha squeezed his hand comfortingly as Bronn pulled out and slammed right back in.
"Oh!" Jaime gasped as the alpha set a punishing pace.
The room was filled with the sound of skin slapping skin as Bronn pounded into him. The feeling was so overwhelming that Jaime could barely form a coherent thought. He moaned and whimpered as that big cock stretched him to his limit and brought him closer and closer to orgasm.
"You like that, princess? You gonna cum while I fuck ya?"
Jaime frantically nodded, whining and squeezing Brienne's hand.
This felt just as good as his alpha's golden cock had. Jaime decided that he loved being penetrated.
Soon, the alpha knight let out a grunt as he shoved his knot into Jaime's asshole and came. Jaime wasn't far behind, and it only took Brienne stroking him a few times to bring him to his own orgasm.
Brienne kissed her exhausted omega's forehead as he leaned back into her chest and promptly fell asleep with Bronn's knot still resting inside of him.
"Sweet dreams, my darling. Alpha will be right here." she whispered, ignoring the other man's presence.
Bronn may have gotten a taste of Jaime, but at the end of the day, the golden lion belonged to Brienne alone.
