Write a detailed story with a lot of dialogues, about two characters based on this: (Kefra and Gixcaririxen ventures into The Hobbit universe, in which they meet Smaug, who they initially confront for all the evil actions he has committed, towering over him with all their kaiju-sized bodies, with Kefra telling him he's nothing but mere dirt that she should scrape off of her feet. But after a while Kefra comes up with an idea that could make this fun for her and Gixcaririxen, even though Gixcaririxen isn't exactly convinced, but he decides to trust her. After having reduced their sizes to be comparable to that of Smaug, Kefra goes to Smaug and says to him that she has seen in Smaug memories, that now she realized the mistake she was about to make and that she realized he's FAR better than her husband in every way, as Gixcaririxen "never was as great as him" and even shows Smaug her butt, inviting him to fuck her.)

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.]
