Kellen placed one last stroke on the summoning circle with the chalk before tossing it aside. It made a satisfying clatter on the bare stone of the chamber. Hours of work had gone into this, a vast collection of ancient runes of summoning and warding spread out across the weathered stone floor. He stood, stretching out the sore spots on his kinked back and his eyes drifted up to see Magister Shan, leaning back on the wooden desk of the study, eyebrows arched imperiously at him.
"It's done." said Kellen. The Magister was an enigma to him, narrow, severe face framed by close cropped silver-gray hair, softened only slightly by a pair of gold rimmed spectacles that they peered over. Not Miss, or Mister, but Magister Shan, as Kellen had learned early on in their acquaintance, and he was certainly not going to argue with his teacher.
After Kellen was cast out by the Grand Academy, there were only so many options if one wanted to learn magic, to gain power over the secrets of the universe. There was so much beyond the little parlor tricks and illusions that were shown off on street corners, but it was locked away behind closed doors and aristocratic lineages. If one was a noble, they could learn, but for someone like him, that path was closed. There was no counting how many people he had bribed, how many dim and dark paths he had tread in order to find a teacher. The journey had led him here, to this cold chamber, lit only by candlelight, scraping runes from a long dead language on a bare stone floor.
When Kellen had asked for power, for knowledge, for any hint of bettering his fate, so cruelly cut off by those petty, pompous nobles at the academy, most had scoffed. A few however had heard whispers of whispers, a mysterious practitioner of forgotten arts, a master of the arcane and the occult, the Magister of the Forgotten Library. Kellen had spent countless hours tracking down those rumors, and now he stood, waiting to be judged.
"What's next?" he asked. The Magister merely tilted their head and smiled..
"Next is simple, and all too obvious, supplicant." said Magister Shan, leaning against their desk with one delicately splayed hand. "What can a mere mortal like you do to pique the interest of a sleeping god?"
"Another riddle?" Kellen frowned.
"Did you expect anything less?" replied the Magister, tapping a finger against their desk, a sturdy beast engraved with intricate whorling designs that to Kellen resembled tangled roots. Kellen sighed, this had been their relationship so far, riddle after frustrating riddle. Either the Magister was under a geas to not say anything straightforward, or more likely they just delighted in his torment. They stood like that, a predatory bird perched upon its roost, waiting, as Kellen wracked his brain, searching through their conversations, through the memory of ancient tomes plucked from grasping skeletal hands on his journey of knowledge, through spells and rituals found only in forgotten tombs.
"Fuck you." said Kellen, lifting his head.
Magister Shan laughed, throwing their head back, a mocking lilting thing that echoed across the stones. The candles ringing the room flickered, casting dancing shadows across the laden bookshelves that surrounded the open area where he had placed the circle.
"No, I mean it, fuck you." Kellen stepped forward from where they had drawn the circle, filled with a sudden boldness that belied his slight frame. "You said that this isn't a sacrifice; this is a bond, a contract, an enticement for them to take notice! If I offer blood, what comes will seek blood, and drink until I am dry as a desert, but if I offer pleasure-" his voice trailed off.
"Oh, dear little one." Magister Shan's eyes flashed as they reached up to take off their gold rimmed glasses, placing them on the desk behind. Their other hand reached up to the clasp at their cloak, plucking at the piece of metal cast in the shape of an octopus. "I cannot count how many supplicants have turned into a snack for the great one by baiting their trap with blood."
"So, so my theory was right?" asked Kellen, suddenly shy, he watched as the Magister loosened the clasp, and the dark fabric fell away, revealing that the Magister wore nothing underneath aside from strange tattoos curling like ivy around their body. His eyes lingered on their small high breasts tipped with dark areolas, seemingly framed by the design of the dark tattoo. The lines continued dowards, wrapping around their body before gathering in a curved knot around their belly button, resembling something like the head and antlers of a great deer. Then his eyes dipped lower, to where their lower lips were laid hairless and bare, pale skin shining in the candlelight, and he fought unsuccessfully against the blush that was rising within his cheeks. To Kellen, their body seemed beautiful and timeless, as if carved from marble, and he couldn't help but feel a stirring, as his cock pressed against the confines of his clothes.
"You know I can't tell you that." said Magister Shan, as they pointed downwards with a single crooked finger. "Come supplicant, test your theory, bait your trap, see if you can catch the eye of a great one without being swallowed whole."
Kellen stepped forward, entranced, falling to his knees in front of the Magister's spread legs. He leaned forwards, planting gentle kisses along the length of their bare thigh. A brief sigh from the Magister reached his ears and he dared to glance up, only to see them staring back down at him, a wry, mocking smile on their face. They reached down, warm fingers running through his soft, silky hair as they grasped at the back of his head, and guided him.
"No teasing little one. The time for that is already past." Shan's voice was a soft purr that disguised an iron will.
"Yes, Magiste-" His words were cut off as the gentle insistent pressure pushed his face against their crotch, and he had no choice but to open his mouth and start licking, tongue darting into warm, salty folds. The pressure on the back of his head was constant, and it was all he could do to try and breathe as the Magister ground his face against their pussy. As his tongue found their clit, their hips started to undulate, using him as nothing more than a sentient fucktoy. Greedy and insistent, he felt warm thighs corded with muscles press around his neck, drawing him in closer.
The Magister's juices coated his face as he continued to probe their depths with his tongue, and he couldn't help but let out a needy, eager whine as they continued to use him. His hands fumbled at his tights, trying to free his hardness from its confines, threatening to tear open the thin material as he desperately lapped at the sweet ambrosia. The Magister arched their back, cutting off Kellen's air supply, and he started to fade, letting his mind float as his vision, his world closed down into the one task set before him, one hand planted on their warm thigh, the other stroking his own aching hardness.
Suddenly, the Magister's grip tightened, fingers entwined with his hair, they pulled him back and Kellen gasped for breath, dark spots floating across the edges of his vision. Magister Shan glanced down at him, their eyes were whirling pools of darkness, their fangs shining in the moonlight, fangs that he swore weren't there a minute ago.
"Tsk, tsk. Touching yourself without permission are we?" They crooned, as they slid a bare foot up to his cock, smearing the dribble of precum that had collected around the head. Kellen moaned and his hips began to thrust reflexively as they drew back, instead gliding their foot up to his chest and pushing him back with a quick shove.
Unbalanced, Kellen fell --but instead of the impact of hard stone that he expected, he landed in the warm embrace of soft, pliant flesh. There was a moment of confused panic as he struggled to regain his footing. Magister Shan let out a mocking chuckle, dragging a finger slowly across their lower lips before tracing patterns in the air, completing the summoning.
"What? The circle!" Kellen cried out, glancing around to see that he had landed right in the middle. A strange eldritch glow surrounded the border, the ancient runes he had spent so long scribing into the stones were flashing with incandescence. Within, the summoning circle was filled with dark, writhing forms, long rubbery appendages that moved and shifted beneath him. They curled around his wrists as he attempted to push himself up, soft and slick, and yet stronger than his thin limbs could escape. He watched helplessly as they restrained him, any light body hair dissolving underneath their secretions, leaving behind sensitive, unblemished flesh.
