Deep in the heart of a heavily guarded castle on the coast where the Abyssal lands met the Voidal Sea, a lesser demon entered the complex that housed his master's harem with a golden key only he and a few trusted others possessed. Located deep underground among the foundations of the castle, the maze of opulent chambers was nigh impregnable by might or magic and more heavily guarded than the treasure vaults of most Temporal kingdoms.
Then again, the contents of this particular 'vault' were more valuable than any gold or gems. A great demon's harem was, in many ways, the source of their power, after all. concubi were the only class of demon capable of birthing the sins and woes that fueled a great demon's magic and allowed them to influence the world of mortals— and Caerophon, Seventh Lord of the Abyss, had over a dozen in his harem.
There were several concubines in the elaborately decorated central chamber when the lesser demon, Oraphel, entered and all of them turned to look at the sound of the doors opening. Demons as a race came in all colors and builds but concubi tended towards human proportions and every single one was so beautiful as to be considered a work of art. Despite being able to change their forms at a whim, Caerophon had always preferred incubi (concubi with masculine features), and thus was every member of his harem— some slim and willowy, others muscular— still more somewhere in between. Each sported a crown of horns, carefully manicured claws, and delicate wings not unlike a butterfly's that spoke to their shared heritage with the fae.
Dressed in the finest fabrics and a glittering array of jewelry, every last concubine was more than capable of drawing the eye, but all in a room together there was one in particular that captured one's attention. Draped gracefully across a chaise lounge at the center of the chamber was one incubus with hair white as snow, vivid blue eyes, and twin obsidian horns sprouting from his brow. His skin was pale as moonlight and had a subtle pearlescent sheen that made him shimmer under the gentle light of the chandelier when he turned to regard Oraphel. His head cocked in silent question, a mere look enough to communicate his unspoken question.
Why are you here?
"My master has returned from abroad," Oraphel announced to the room at large— though it was to Malachi, Caerophon's first consort, to whome he bowed his head.
The declaration immediately sent a thrill of excitement through the collected concubines and several immediately sprang to their feet and left for other rooms and halls that branched off of the central chamber to ready themselves until only Malachi remained. He seemed unaffected at first glance, but anyone familiar with his mannerisms would recognize his poise as a thin veil for the anticipation burning within him by the subtle pursing of his lips and the way one carefully manicured hand went to his stomach.
"Thank you, Oraphel. Tell my lord we await him at his earliest convenience," Malachi said with a slow smile and forced himself to relax back onto the chaise lounge once more.
The lesser demon left after making another bow and Malachi cast his gaze towards the arched ceiling overhead then swept his hand over the flat of his stomach. Caerophon had been abroad for the better part of a month and while there were plenty of diversions to be found among his fellow concubines, no one could hold a candle to their master.
A shiver of anticipation raced up Malachi's spine and he slid his hand past the hem of his silk underwear to find his clit. Significantly larger than a female's, it was already rigid when Malachi's fingers began to tease its length in preparation of what was to come. By the time the door opened a second time a few minutes later, Malachi was slick and ready, skin flush, scant clothing long since shed.
"My Lord," he gasped and withdrew his fingers from his depths then spread his arms in invitation to the great demon that had just entered the room.
Caerophon was built on an altogether different scale from the members of his harem. Nearly twice Malachi's height and at least twice as broad, the great demon was all brutal, heavy muscle with a thick waist and massive hands that made even the strongest of the incubi feel fragile as blown glass. His crown of hooked horns was just as impressive as the rest of him— as were the array of scars that decorated his mottled crimson skin.
He was already undressed to the waist and Malachi was pleased to see the front of his pants were under significant strain— a problem that only intensified after a moment's admiration of his most favored concubine.
"So thin," Caerophon growled as he advanced on Malachi, thick, calloused fingers already working on the clasp that was barely holding his pants closed at this point.
It took everything in the incubus not to whimper at the sight but he nodded and slid both his hands up his thighs and over his flat belly before lifting them to reach for his lord once more. "You were gone so long," he opined. Soft lips, pink as a rose petal, spread as he tilted his chin up in silent invitation for a kiss— or something else. "You'll fix that, won't you?" he asked as he looked up at Caerophon from under the sweep of his long lashes.
"Would you have someone else?" the great demon asked, deep voice rumbling up from the barrel of his broad chest in that way that made Malachi's toes curl with anticipation. Caerophon had finally managed to shuck his pants, leaving him standing before his concubine, huge twin cocks erect and already leaking precome in anticipation of what was to come.
Malachi sighed happily at the sight of them and leaned forward to take the very tip of the first between his lips, tongue lathing over the head to clean it. The shafts, normally sheathed within the confines of the great demon's body when he wasn't aroused, were long, thick, and ridged. If restraint was used, Caerophon
