Part One: A Queen And Her Throne

The Goddess of all Dragons. The Fivefold Queen. Tiamat.

Her 'throne room' of sorts is vast and lavish, filled with piles of unimaginable wealth, accrued over her tens of millions of years of existence.

Contrary to at least what WAS draconic nature, Tiamat has little attention for her nigh-unlimited wealth. Even besides it growing old over her multi-millennial divine life, far exceeding that of even her oldest mortal chromatic dragons, Tiamat has something far more important on her mind.

Five sets of eyes watch the heavy shaft in front of her swing back and forth. A tongue flicks out and teases at the tip, eliciting a body-wide shudder from the multi-headed queen's 'throne'.

The Fivefold Queen smiled a fivefold smile as she looked down at her makeshift seat. There was a time when the name Bahamut commanded respect. He was known throughout the worlds as a champion of justice, a strong leader for the noble metallic dragons.

Not so any more.

Bahamut's once powerful physique was nowhere to be seen. Where he once had abs of adamantium, was now a soft, narrow waist. His strong visage now dainty and effeminate, and his once impenetrable hide now replaced with silken-soft scales. His shoulders and hips had apparently traded sizes, with his hips reneging on the deal and keeping both, now exceeding even the size of his sister's wide rear, with heavy thighs to match.

The only trace of Bahamut's masculinity to remain was his massive shaft and balls. Indeed, his latent transformation had only increased their size, swelling them to obscene proportions, thoroughly impossible to conceal even if his sister ever allowed him a moment of unaroused peace.

Bahamut had never expected that his sister could ever best him, let alone in such a twisted way. But yet she had, her hundreds of thousands of years of hateful hidden lust boiling over, driving her into an unstoppable frenzy that few in the cosmos could withstand.

And so, here Bahamut lay. With an effeminate body whose overcharged urges betrayed his mind. With a collar on his neck and a ring on his shaft, blocking him from even the most minor of releases. Stuck on his back, with his domineering, eternally lusty sister using his face as a seat while she plays with his bouncing member.

Tiamat pauses, watching her platinum brother's shaft swing back and forth. With a set of wicked smiles, she opened her mouths and her five tongues reached out to flick and tease at Bahamut's inordinate endowments, rolling over the heavy, twitching flesh. Bahamut's previous twitching grew into what could almost be described as thrashing, his massive hips thrusting impotently into the air as five separate draconic tongues wrapped around his throbbing meat. Runes flared into visibility on the ring at the base of his shaft, completely blocking the release denied to him for what was now several mortal weeks, producing an almost pained moan from beneath the dragon-queen's ass.

A loud bang echoes through the expansive chamber, briefly giving pause to the roiling of Tiamat's tongues. Briefly.

A black dragon strides down the carpet, his chest puffed forward. In tow behind him was a female red dragon, manacles around her feet.

Tiamat's red dragon head ceased it's ministrations on the shaft before her, addressing the black dragon. "Veracus..." She hissed. "Have I not told you not to interrupt me during my... convalescence?"

The offending dragon deflates slightly. "Infinite apologies, my queen, but your... convalescence has lasted several weeks now. And the accused..." He tugs on a chain, pulling the shackled red forward. "Need judging."

Tiamat gives a bored sigh, even as her four other tongues continue teasing her brother's shaft as he writhes ineffectually beneath her, locked on the pinnacle of release.

"Very well." She acquiesces. "State the accusations."

Veracus puffs himself up again. "Allera The Red, of the Quickscale Summit stands accused of violation of a temple of our most glorious queen. She must be-" The black dragon halts his minor tirade. Tiamat's red dragon head has gone back to toying with her brother, evidently no longer paying attention.

"Your majesty, please-"

"SILENCE!"

The reaction was instantaneous. All five of Tiamat's heads momentarily cease their fun and glare at the offending black dragon, speaking in terrifying unison. "YOU HAVE EXHAUSTED OUR PATIENCE. REMOVE YOURSELF, LEST WE REMOVE YOU."

Veracus visibly wilts at the goddess' explosion. He shakily reaches for the captive red's chain.

"WAIT..." Veracus freezes.

Tiamat's red dragon head smiles, a wicked smile that tells of things to come. "Leave the girl..." It says.

Veracus holds for the slightest of moments, then scurries for the door as quickly as he dares. The slam of the door closing echoes through the hall.

Tiamat gazes down at the shackled Red. "I'm feeling generous, despite being so rudely interrupted. You may choose to be incinerated..." Allera's eyes widen. "Or..." Tiamat continues. "You can play a little... game with me. Am I to assume you would prefer the second option?"

The captive chromatic looks around nervously for a moment, then swallows and nods. Tiamat smiles. "Most excellent." She narrows her gaze. "Turn around."

Allera blinks, uncomprehending. "Turn. Around." Tiamat restates. "You're always free to choose the first option if you wish."

Allera turns around.

"Good girl." Tiamat smiles, and stands up, Bahamut drawing in a deep gasp of air. Divine lungs may not need to breathe, but Tiamat had grown particularly fond of her platinum throne. "Bahamut." She commands, the platinum god's attention snapping to her.

"Fuck her."

Allera starts. "W-what? You can't-"

"I can do whatever I please!" One of Tiamat's heads barks. "Or am I to conclude that you would prefer annihilation?"

Allera silences herself. Next to Tiamat, Bahamut's eyes are locked on the shackled Red's rear. "Go on, brother dearest. Take her. I can tell you want to. Need to..." She grins a wicked smile. "Who knows, it could be the condition to get off that oh-so-troublesome ring of yours~"

Bahamut gets to his feet, steadying himself. He moves over to the Red and gently runs a claw over her scales. She shivers. "J-just do it."

With a nod, Bahamut presses the tip of his shaft underneath the Red's tail, suppressing a twitch as he does. With a grunt, he pushes forward, eliciting a gasp from both dragons as the tip of Bahamut's gargantuan cock pushes into the Red's folds. Slowly, he pushes forward, his eyes rolling back as he slides deeper into his red lover, her legs shaking until her forelegs give out completely, collapsing and leaving her ass in the air.

After what seems like an age, Bahamut hilts himself in Allera's body, his breathing back to ragged gasps, and her stomach sporting a visible bulge from the platinum dragon's massive shaft.

Back in her much less interesting seat, Tiamat watches with a smile. It fills her with such joy to see her brother having fun.

Allera meanwhile, is continuing to be fucked into the ground. Each thrust sends a bolt through her brain, and she can't tell if it's pain or pleasure. Bahamut's eyes are rolled back, and his tongue hanging out as he pounds into the Red below him. His pace increases, his ring beginning to glow. His impromptu lover gives out a short, sharp gasp with every thrust, now far beyond rational thought.

Bahamut's thrusts become erratic, his ring again denying him his climax. Allera, however, has no such limitation. With a final moan, her entire body tenses, extracting an agonized gasp from Bahamut as her stretched body squeezes his shaft, then goes limp, falling into unconsciousness.

"Nicely done, brother~" Tiamat smiles as Bahamut starts to slow down, his thick legs shaking. "About the ring though..." One of her heads produces a quick chuckle. "I'm afraid I lied~"

Bahamut sways where he stands before falling over, falling out of the unconscious Red with a slick noise.

"Tut-tut" Tiamat scolds. "Over here now~" A faint magical glow surrounds Bahamut and Allera. Bahamut is levitated back to his sister, while Allera is left on a pile of gold coins to the side.

"You deserve a treat after that, wouldn't you say, brother dearest?" Tiamat teases, two of her heads lowering to again lap at his now-wet shaft. Bahamut begins panting again, his cock twitching. "Hhhh... p-please..."

Tiamat gives another of her wicked grins. "Oh, look at you now, my oh-so-majestic brother. Once you were what many aspired to be, a strong, handsome, noble hero for all the worlds... And now look at you." A third head joins the first two. "Fucking girls into unconsciousness, begging to be let to cum, being nothing but my plaything..." A fourth, while the remaining head leans forward, whispering in Bahamut's ear. "...And loving every second of it."

Bahamut doesn't respond outside of another lusty gasp.

"Well, I suppose you did ask nicely." Tiamat puts a claw on the back of Bahamut's head, pushing him forward, his open mouth engulfing the tip of his massive cock. With yet another smile, she puts a claw on the furiously glowing ring, and tapped it three times.

"You have my permission."

Bahamut's shaft exploded into a torrent of seed, the results of several pent-up weeks of near constant arousal. With the pressure his sister is applying to the back of his head, the torrent flows down his throat into his stomach.

Tiamat giggles and her four other heads return to teasing her brother's gushing shaft, eking yet more seed from his heavy, full balls. Bahamut's stomach begins to bloat outwards as he uncontrollably fills himself.

"There's no going back from this, Bahamut." Tiamat teases her self-stuffing brother. "You are mine, from now until the end of time~"

Bahamut's pent-up tide eventually exhausts itself, and his sister releases his head. Panting heavily, eyes vacant, he leans against his sister, who gently strokes his stuffed, sloshing middle.

"That's a good boy~"
