A Familiar Spell, Part One

"Not enough mana? Preposterous!"

Anna paced the room, frustration oozing from her every movement. She cast a venomous look at the grimoire that sat, open and innocent, on her bedside table. The tagged page that stared up at the ceiling bore a long, complex spell, written in a tongue not often spoken by mortals. The language of demons, taboo as it was, was a beautiful language as poetic as it was complicated, and it was vital to casting many spells of overwhelming power. At that moment, the ancient characters seemed to mock her, dancing across the page in fading candlelight.

Anna was a witch, deadly and brimming with ambition. She had spent many years mastering her craft and cultivating a repertoire of spells for any occasion. She was quite possibly one of the most powerful creatures on the mortal plane. And yet, she grew bored. Restless.

She did not wish to just be an exceptionally powerful mortal. She wanted to be so much more than that. So, after a long and bloody excursion, she procured this particular grimoire, written by the ancient demons of the hellish planes. Surely, to go beyond human confines, the witch figured she must learn the ways of those wicked and wild devils. However, despite the impressive lengths she had gone to in obtaining the damned book, Anna was met with yet more hurdles and irritation.

"How much mana can a single spell require?" she hissed, half a mind to burn the book to a crisp for such insolence. She quickly beat down those irrational desires, knowing no good would come of such destruction besides a fleeting moment of satisfaction. She inhaled slowly, then breathed out a calming sigh. "No... no matter. There are ways of remedying such trivial obstacles. Simple, if perhaps... humbling." She huffed slightly at the thought.

Tossing her curls over her shoulder, she strode away from the grimoire, around her bed to a large bookshelf. Tracing a long-nailed finger along the spines of countless tomes, she finally plucked out one particularly large volume, falling back to her bed. She lay the book open on her lap, quickly flipping through the pages with far less care than their delicate parchment deserved. She paused in her flipping, gazing down at the spell.

"Perfect," she said grimly, none-too-pleased with what the accursed grimoire was forcing her to do.

In all Anna's years of witchcraft, she had never resorted to using a familiar. In her mind, it was a crutch that only served to weaken a mage in the long-run. She'd rather rely on herself and her own talent than let some creature take even partial credit. And yet, desperate times called for desperate measures.

She set about preparing the summoning, gathering necessary ingredients and offerings. She drew an intricate conjuring circle upon the marble floor, admiring how its blood red curves contrasted the white stone. She stood back, tome in hand, and whispered out the incantation, allowing her voice to quietly wind into the magic. Her eyes fluttered close as she felt the familiar sensation of mana leaving her body, and when she opened them again she was no longer alone.

"Ah. A conjuring? How classy. Nowadays so many mages go straight to binding, it is rather... rude." Golden eyes bore into her own. A creature much like a man stood in the summoning circle, bare feet testing the lines curiously. His skin was an ashy gray, lined with intricate golden tattoos much like veins, or a sprawling spiderweb. Thick white hair fell to his shoulders, and he was conspicuously unclothed. "It's so nice to at least have an introduction before binding, don't you think?"

A wide smile crossed Anna's lips. "You are not what I expected," she said, looking rather pleased at that fact. "It is nice to meet you. I am the witch Anna. And which Circle are you from?"

The demon mirrored her smile. "Second. A pleasure to meet you," he bowed, "and to defy your expectations. Now what can I do for you, Mistress?"

Smile only growing, Anna cocked an eyebrow and laughed, "'Mistress'? You certainly are quick to serve." She smoothed her robe carefully, stepping close to the circle. Measuring up to the creature, she could not match its height or musculature, which only made the feeling of dominance sweeter.

"I may not be bound to you yet," he said, smile turning wry, "but we both know whose domain this is. I can only imagine this is business, not pleasure, so might as well get cracking, yes?"

"How astute. On the topic of domains, I wish to move from mine to yours, demon." She gestured carelessly to the grimoire still open on her table; following her motion, the demon peered curiously at the book. "However, it seems the mana required to make such a leap exceeds my reservoir at the moment. Thus, I require your aid."

"Please, call me Tirath, Mistress." He cocked his head mockingly. "So, you wish to venture the hells to sate your lust for power? Interesting. I like it. I pledge my power to you in this endeavor, and swear to deliver you to your desires." He knelt, bowing his head, and Anna felt a rush in the pit of her stomach unlike anything she had ever felt. So this was what it was like... Reluctantly, she began to understand the appeal of familiars. "Now, Mistress, let me out of this circle? Pretty please? I can hardly serve you from in here..."

Anna laughed again. "Of course, Tirath." With a wave of her hand, the magics supporting the circle evaporated.

The demon sighed and sauntered forward, nearly pressing against his mistress. "Thank you for giving me release," he breathed, his clawed hands cupping her cheeks tenderly. He ran his thumbs over her face, careful not to scratch the pristine skin. "So what can I do for you, Mistress? Tell me, command me. I am at your disposal." His words were almost a whine, begging for her approval.

She deigned his pleading with her first task: "I need more mana, first and foremost. Grant me what I need to complete the spell."

"Gladly." Tirath smirked, showing off pearly fangs. His hands slipped from the witch's face down to her chest, cupping her modest breasts. "Of course, you will need more room to house such power, Mistress. Humans aren't built like demons, but we can find ways to... accommodate."

Anna gasped in surprise as the demon's hands pulsed with energy. Tingles erupted across her skin as his fingertips glowed blue; the feeling spread from her nipples out across the flesh of her breasts, starting as a gentle sensation but gradually increasing in intensity. Staring down at her chest, the witch was shocked to find that her breasts were slowly growing in the demon’s hands.

The dark fabric of her robes stretched as her tits rose like two loaves of bread, her nipples thickening into two hard points that now nearly grazed Tirath's bare chest. The demon, though deep in concentration, managed a sly grin as Anna moaned at the contact. "Sensitive, are you? Being forcibly filled with mana tends to do that." He began moving his hands, still pumping mana into the witch, and rubbed the expanding flesh with a certain reverence. "O Mistress, how beautiful you are, how sweet your voice..." His words were singsong and playful, yet held a note of sincerity.

For once, Anna's words had abandoned her, leaving her defenseless as her breasts swelled. They had gone from the size of oranges to melons in but a minute, stretching flesh trapped in the tight confines of her robes. The tops of her tits squeezed out of her neckline, her own cleavage soon threatening to smother her. Pressing forward, Tirath guided Anna backwards towards the bed, pushing her down onto it. He paused the mana transfer just long enough to slightly rip the neckline of her robes. That was all it took for the dam to burst; a great tearing sound echoed through the chamber as the fabric shredded under the pressure of the witch's enormous bosom. Wide expanses of flesh left open for the world to see: shapely legs leading up to slender hips and a similarly petite torso, comically dwarfed by her chest. Under the robes, she wore only simple white panties. Each breast had reached the size of a prize-winning pumpkin, no doubt.

Settling between her legs, Tirath looked down at Anna as she lay there, surrounded by the tatters of her robes and held down by the weight of her swollen breasts. She held his leash tight, but there was plenty of satisfaction to be found in the sight of her own vulnerability. Her chest heaved with each gasping breath she took, thrumming gently with the energy of mana. Her nipples stood stiff, proud and pink, into the air, and small blue beads were starting to leak from the caps: pure mana. Again, Tirath halted the transfer, leaning down slightly. An unnaturally long tongue darted from his mouth to swipe the dribbles of mana from her teats, eliciting another whimper from the witch.

He hummed, pleased. "Demons and humans, we have very different energies. Something about you humans... your mana is delicious. Even if it's just demon mana that's been given to you, you add such a wonderful flavor. I could just eat you up." He took one plump nipple in his mouth, sucking another quick taste from it before Anna could say a word.

Biting back another helpless moan at the admittedly pleasurable sensation, the witch instead put on a cross expression. "I need that mana, don't be greedy," she admonished, reaching an arm around her towering bosom to push the demon off her nipple. He left a trail of saliva as he went easily, shooting her a devilish grin as he nuzzled into her touch.

"Of course, Mistress." He squeezed her breasts quickly, another pulse of mana flowing in. Anna cried out involuntarily as her tits puffed up another inch, more mana droplets forming at her nipples. Tirath happily licked those up, looking smug. The witch had a feeling her breasts were reaching their limit as far as mana storage went, and she looked them over critically.

"Are you tiring, Tirath? It must not be easy to give so much mana," she said casually, running a hand over the impressive curve of her bust.

The demon cocked his head, smiling curiously. "Are you worried? Think of it like this: mana is like water. A human mage holds within them a well which they can draw buckets from, but must take care they do not run it dry." He leaned back, pressing a hand to his chest. "I am the ocean."

Anna scoffed, torn between annoyance and amusement. "Point taken. And for the record, I was not worried about you, I was merely concerned you would be spent so quick." She tensed somewhat when she felt Tirath's hands settle on her thighs, claws digging in ever so slightly.

"I assure you, Mistress, that shall never be a concern with me. Take as much as you like, I shall always have more to give." His eyes gleamed as he stared down at her.

She thought for a moment, before the corners of her lips quirked upwards. "A generous offer. Do you think this is enough mana to secure transport to the hells?" Anna pressed her hands against her gigantic breasts, hefting them upwards. The flesh was firm, but jiggled slightly when touched. So much many contained within... she had never felt more powerful. As her fingers brushed her swollen nipples, a shiver ran through her body. Powerful AND sensual.

"Well..." For the first time, Tirath hesitated. Anna looked at him shrewdly, and he shot back a grin. "Before we get to that, it would be wise to at least make sure you can control the power. It is foreign to your system, and not all humans can assimilate demon mana. Try some lesser spells, first."

Anna had never performed a spell while pinned to her bed, but a witch of her caliber should have no problems regardless. She took a deep breath, sending a tremor through her bosom, and concentrated. A simple telekinesis spell to rearrange her bookshelf would do. Turning her head towards the shelf, she focused, mentally drawing every book out at once... and gasped.

Never had casting felt like this. Something cool and fluid rushed down her body, from her enormous breasts down through her stomach before settling squarely in her crotch. Where the books should have slowly slid out, they were instead torn from the shelf as if by some powerful gale. Anna's lower body erupted in tingles, heating up until her insides felt painfully tight. The pressure built to a head, and then snapped. The witch screamed out in orgasm, clawing at her bed sheets wildly. To the side of the bed, the books all shuddered in midair, before tumbling to the ground in a mess. Her panties were drenched as she came down from the high, a fact that greatly interested Tirath. He stared at the white fabric, which was now being stained blue.

"Huh. Interesting." He dragged a hand across Anna's thigh, getting closer to her groin.

"W-what's interesting? What just happened to me?" the witch whimpered out, her panting causing her breasts to bob violently. Peering down at her breasts, she noticed that they had shrunk slightly. Despite this, they were still absolutely enormous, simply not quite as stuffed to the brim as before.

One of Tirath's claws hooked around Anna's pantyband. "Clearly you can use the mana just fine, and it seems to have greatly magnified your spell's effect. However, where a mage's expended mana would normally cycle back to the mage after time and rest, your body seems to have expelled it instead. It's gotta leave somewhere, right?" With a quick upward swipe, the demon disposed of her panties in a second. He cocked his head, admiring her waiting pussy, slick and blue with the spent mana. A manic grin crossed his face. "Delicious."

"Ah--OH!" Anna's head thrust back against her pillow, back arching as Tirath threw her legs over his shoulders. Claws digging into her hips, Tirath eagerly ran his tongue along her slit, licking up any trace of mana. The witch bucked as he took her folds between his lips, sucking shallowly on the bits of flesh. Moving up, Tirath pressed his lips against her swollen clitoris, tongue flicking out to tease her. He relished her delighted moans, turning his head to press a kiss into her inner thigh. The kiss turned into something else when his lips parted, leaving behind a nice little hickey. Running his mouth over her once more to ensure he got all the mana, he hummed contentedly against her pelvis.

"Delicious," he repeated, utterly satisfied.

Anna mustered a breathless laugh. "Aha... I can finally see why familiars are so popular," she admitted, carelessly brushing her curly hair out of her face.

"Depends on the familiar, really," he shot back slyly. He reached up and lazily flicked one of her fat nipples, enjoying the resulting shiver that wracked her body.

"You beast!" she gasped playfully, clearly having fun as well. She reached around her giant breasts to ruffle his hair affectionately, as that was pretty much the furthest she could reach. "Well... I can see it will take some time to grow accustomed to your mana. I'll definitely need more to get to the hells... Planning on sticking around for awhile?"

He caressed one huge breast lovingly, his fingertip starting to glow blue. "Gladly, Mistress."
