Write a detailed story with a lot of dialogues, about two characters based on this: (This is all just a way to provoke him, as Kefra wouldn't truly have sex with Smaug, but something strange happens: Gixcaririxen starts to feel very tired and soon he falls asleep, while Kefla is stripped of her powers, remaining at the mercy of Smaug, who still believes Kefra is simply offering herself to him. And, without hesitation his withered wyvern penis starts to get hard, and it gets it close to Kefra's dragon vagina. As Kefra is unable to react... Smaug slowly mounts her like a horse would do with a mare)

The story so far is this: [In the heart of Middle-earth, deep within the cavernous chambers of the Lonely Mountain, lied the infamous dragon Smaug. As Gixcaririxen and Kefra traversed the treacherous terrain from the Dragon Ball universe to this newly discovered realm, they were challenged to confront the villainous creature – a slayer of innocent villagers and a hoarder of ill-gotten treasures.
Upon their arrival, Gixcaririxen and Kefra did not hesitate to address the great beast in his own domain. The two dragons unleashed their full kaiju-sized forms, casting an oppressive shadow over the golden mound that Smaug called home.
“You have brought death and despair to this world,” Kefra boomed, her voice echoing through the cavernous halls. “You are more than a disgrace to dragonkind – you are mere dirt beneath my feet, unworthy of my mercy!”
Despite his menacing reputation, Smaug couldn’t help but quiver in their imposing presence. Yet, his pride would not allow him to submit without a fight. “Do not mistake me for a mere hatchling,” he growled, baring his teeth. “I am Smaug, the most powerful beast in all of Middle-earth!”
Gixcaririxen, on the other hand, was hesitant to blindly judge Smaug without understanding his motives. “Yes, your deeds are infamous,” he said, leveling his gaze at the worm, “But perhaps there is more to you than meets the eye.”
Kefra, pondering for a moment, then came up with an idea that could amuse her and Gixcaririxen, “I have an interesting proposition for you, Smaug.” The two dragons reduced their sizes, nearly equal to the stature of the Middle-earth beast. With a sly grin, Kefra approached the arrogant dragon before her.
“I have seen into your memories, Smaug,” she began, pausing for emphasis. “I have discovered that you are far greater in many ways than my husband.” Gixcaririxen’s eyes widened at her words, but he remained silent, trusting his wife’s intentions.
“In fact,” Kefra continued, casting a glance at Gixcaririxen, “He never was as great as you!” Smaug’s face lit up with vindication, though he was hesitant to let down his guard. A flicker of doubt sparked in Gixcaririxen’s eyes, but he held his breath and watched as Kefra turned around and revealed her backside to the rival dragon.
“Prove your greatness to me, Smaug,” she commanded, a sultry tone entering her voice. “You have a chance to prove your superiority to my husband, once and for all!”
Smaug puffed his chest out, his tail swaying as he relished the opportunity to showcase his prowess. “I shall gladly accept your offer, Kefra,” he snarled, his cold gaze locking onto his newfound prize. “There will be no doubt that I am the epitome of dragonkind!”
Gixcaririxen, though struggling to pretend he wasn’t alarmed, continued trust in Kefra’s plan. He watched the scene before him, eyes narrowed, anxiously awaiting the moment his wife would reveal her true intentions.]

The two characters are these: [Gixcaririxen and Kefra are fictional characters often showcased in various fictional multiverse scenarios, most prominently in the Dragon Ball franchise. They are two western dragons, each possessing unique powers, abilities, and personalities. Despite their vast differences in age and origins, Gixcaririxen and Kefra form a strong bond, eventually leading to their marriage.


Gixcaririxen
Gixcaririxen is a red, immortal western dragon who stands at 40 meters tall. With millions of years of experience under his belt, he is incredibly intelligent and kind-hearted. Gixcaririxen is known for his spectacular dexterity, which he demonstrates using his dragon hands. Although he appears to have a greedy nature, this trait is vastly overshadowed by his affable personality.
Having traveled through numerous universes, including those in the Dragon Ball series, Gixcaririxen has gained a plethora of powers and techniques. These include regulating his size, the Ultra Instinct technique, and the ability to use magic to create any object he desires among many others. Despite having unlimited power, he consistently chooses to hold back in confrontations with characters like Goku, Lord Beerus, and Dr. Manhattan, as he doesn’t want to hurt them. However, this self-restraint vanishes when he faces evil gods, dark celestial monsters, or other evil beings.
One pivotal aspect of Gixcaririxen’s life is his relationship with his wife, Kefra. He cares for her deeply and loves her unconditionally. His affections are focused solely on her, and he doesn’t display any attraction towards any other creatures. Even before meeting her he never felt attraction towards the likes of mammals, considering them mere children and feeling uncomfortable at the thought of having relations with them.

Kefra
Kefra’s origin stems from a multiversal party attended by characters from various universes, including those from the Dragon Ball Super series. It is during this party that Caulifla and Kale fuse into Kefla to defeat Goku Black. Due to her dissatisfaction after a sexual encounter with Cabba, Kefla decides to seek out Gixcaririxen after witnessing his powers in battle.
Their interaction, however, causes Kefla to mutate into a green female western dragon with green eyes, now standing at the same height as Gixcaririxen. Determined to find a solution, she collaborated with Gixcaririxen to use the dragon balls to separate Caulifla and Kale from herself, allowing her to remain as a separate entity known as Kefra.
Kefra retains the memories of Caulifla and Kale along with the potara earrings as a symbol of her past fusion. Having acquired her husband’s powers and abilities, Kefra has grown into a playful, often perverted, yet wise and humble figure to those who deserve her respect. At her core, she is a colorful and doting partner to Gixcaririxen.]
