Diona and Sera Storry! (Patreon)

Sera glided down on the soft sea breeze and alighted gently on the balcony of the palatial coastal resort. Well, as gently as an 8-foot cockatrice weighing -redacted-  could alight, but given the only minor damage to the ivory tilework, she doubted the management would be so imprudently squeamish as to make a fuss. She glanced around appreciatively at the picturesque estate, taking in the beauty and serenity of the setting. Clear turquoise water washed frothily over the brilliant white sand, mere yards away from the marble walk leading through the manicured garden surrounding the central mansion. The primary building itself was a lovely example of coastal architecture, bolstered with elegant white columns and capped by clay roofing tiles the color of ripe tangerines. The faint scent of salt danced in her nose, entwined with the spiced aroma of incense drifting through the open archway from within. She liked this place already.

Located at the tip of a peninsula on the Adenean Sea, the resort was certainly a considerable distance from her inland domain, but the dearth of reputable brothels on the southern part of the continent left the discerning patron with few alternatives. Well there WAS Madam Lynn's House of Sin... Sera had paid a visit to that place a fortnight ago, intent on running her usual route through a few of the more gently-used wenches. That evening she'd met with stiff resistance from Lynn, the madam, whose customers had recently complained of the increasingly cavernous... accommodations... of her ladies, allegedly caused by the rambunctious romps of a certain cocky cockatrice. Sera, aghast at the baseless recriminations, promptly lodged a fiery complaint with the owner, and departed huffily. It was two days until the locals finally managed to douse that conflagration, which ultimately spread to a nearby field and left three neighboring farms in smoldering ruins. Still, she would miss that place.

She pushed past the extravagant velvet drapery and surveyed the spacious lounge within. There were several gilded couches arranged in a roughly semicircular formation, facing the open archway and the seaside vista beyond. At the rear of the room, an ornate marble staircase proceeded upward, presumably to the more private chambers situated above. The lounge was lavishly appointed, with every article of furniture tastefully selected to convey a balanced measure of both opulence and luxurious comfort. The suddenly agitated patrons were an assortment of well-heeled continental figures: a smattering of royalty, a powerful general, and a few rival warlords (one of whom Sera would certainly kill once her business here was concluded). She nodded politely at the individual in question, whose personage as well as his exposed package both wilted abruptly at the attention. Each of the customers were attended to by no fewer than four exquisitely beautiful escorts, mostly women. A veritable cornucopia of ethnicities were represented among the ample selection of lovelies - in addition to a number of especially comely home-grown locals, there were several elves, of both the northern and southern varieties, a gorgeous trio of dark-skinned Nuvyans (triplets - score!), and a couple of exotic dancers from the Syanese Empire of the Far East, plus a few whose origins she could not discern. There was a bit of commotion as a few of the sweatier patrons attempted a hasty exit, but Sera's reproachful glare apparently convinced them to remain a while longer. It would certainly not do to unnecessarily disrupt the operation of such an impeccably managed establishment so soon after her arrival.

Sera settled her considerable bulk into a capacious velvet couch, which groaned audibly under her weight. She spread her immense wings over the back of the seat and, reaching into her lap, ceremoniously tossed aside the violet cloth that sheltered her blessed loins, revealing the soft dark flesh of her sheath and massive scrotum. She nuzzled the grapefruit-sized gonads gently, shuffling them into a more comfortable position, and then glanced about the room invitingly, availing herself to all comers. Disappointingly, the petrified inhabitants of the lounge remained motionless - only a shuddering sigh from the far corner of the room provided any indication that she had not mistakenly walked into a lewdly configured wax museum.

"I traveled a long way to sample the services of the vaunted Pearl of the Adenean, and this is what I get?" Sera snorted derisively.

"Now angels! Is that a way to treat our newest guest?" Came a silken and sultry voice from atop the marble stair. It's clear melodious tone had an unnaturally soothing quality, that abruptly dissipated the deathly stillness that had inhabited the room. The escorts all relaxed visibly, most resuming their attendance of their guests. A couple continued to stare nervously at Sera, particularly at Sera's crotch, which itself was an esteemed guest of preceding reputation.

"My lady, you really must excuse my angels. Its not every day that a patron of your... talents graces the Pearl with their presence." A statuesque, blue-skinned beauty sashayed with tantalizing slowness down the marble flight. A loose-fitting robe of a translucent red silk draped enticingly over her assets, cascading down into the cleft between her large, full breasts, whose thimble-sized nipples poked teasingly through the fabric. Behind, the twin hemispheric shelves of her high, firm ass jutted proudly outward, jiggling appetizingly with each step. She stepped down onto the plane of the floor, turning completely to face the room, and Sera's eyes widened considerably in appreciation of the view that was thus bestowed. She leveled her captivating yellow eyes directly at the cockatrice, betraying no hint of fear or hesitation. Her lustrous black hair was pulled back into an impeccable bun, and two long crimson horns adorned her azure brow above the perfect arches of her eyebrows. Though clearly much older than the other escorts, her skin retained the taut suppleness of youth, and she carried herself with the unassailable sexual confidence of a succubus at the height of her power. A faint hint of a smile played at the corners of her full sensual lips. "Perhaps I might offer a warm welcome truly worthy of the Twilight Queen?" She crooned indulgently.

Sera regarded the demon quietly for a moment before replying. "It seems that I am the one who is honored today. Word of your talents have truly become legend." She paused before adding respectfully, "Madam Diona."

Diona chuckled sweetly and resumed her agonizingly sensuous walk towards the couch where Sera sat. "Oh, legendary am I? Oh, I don't know about that..." She demurred coyly. She perched herself prettily on the edge of the seat. "I do suppose I have had a few exploits in my day. Ancient history though." She smiled wistfully.

"Ancient history, huh?" Sera retorted. "You don't look so "ancient" to me. Don't tell me you've let these amateurs put you off your game," Sera mocked, gesturing at the madam's young flock. "As I recall, it is you who is the true Pearl of the Adenean, not this edifice to which you have conferred the title."

Diona smiled at the application of her old moniker. "Indeed, I had a good run," she replied thoughtfully, "but we all have to retire eventually. Pass the torch, so to speak. As I got older, there weren't many lovers who could satisfy my needs. Well, without dying anyway." Diona chuckled again, vibrating her shapely bosom delightfully. "Now, the only loads I take are in gold bullion."

Sera smirked, "Well, I have plenty of that." She flashed Diona a mischievous look. "But if you're feeling a little over the hill, I bet I could knock some of the dust off that pussy," she teased.

"Now, now, language," Diona admonished amusedly. She pensively placed a meticulously lacquered nail between her teeth, surveying Sera intensely for a moment, and taking in her powerful physique from head to toe. "Though you don't seem as frail as these mortals... Perhaps you might succeed where others have failed?"

Sera slipped an arm around Diona's svelte waist, pulling her in closely. Diona let out a surprised sigh, and then settled her luscious body against Sera's muscular torso, her thick nipples brushing arousingly against Sera's own. Sera closed her eyes and breathed deeply of the scent of jasmine emanating from the succubus' warm skin. Then she opened them and stared directly into Diona's glowing orbs. "Be careful what you wish for demon. You would not be the first fiend that I have added to my stable." She scanned her eyes over the succubus' voluptuous form. "Besides," Sera said, "blue definitely looks good on me."

Diona smiled at this, placing a firm hand against Sera's chest. With surprising strength she shoved herself backwards out of Sera's grasp, stood and turned away from the cockatrice, offering a glorious view of her magnificent ass. She then cast Sera a backwards glance. "You're all talk." was her simple reply, and she strode sensuously towards the stairs. At the base of the flight she turned expectantly. "Well?"

Sera knew a challenge when she heard one. And she never lost. Over the next several hours (or days, as it might be) one of them would establish sexual dominance over the other - and among demons such as they, such dominance was akin to ownership. 
The cockatrice stood and stretched her enormous wings, causing the guests and escorts to recoil in surprise. She then settled them comfortably against her back, and casually sauntered towards the stairs. As she followed succubus upstairs to the guest room above, Sera slyly offered a bit of cautionary advice.
"I think it's only fair that I warn you. Cock-a-thrice is quite habit-forming..."
