The Summoning
The sounds of potions and arcana at work pop and whir around Anna as she prepares the summoning circle. It's taken weeks of research, days of prep, and about two hours of baking. Demons like cookies, right? Anna thinks to herself, drawing out the final lines of the summoning circle in arcane chalk. Kneeling, Anna leans back, resting her behind on her heels to admire her work. Perfectly arrayed out in front of her is the most challenging piece of arcana she had ever worked on. A demonic summoning circle meant to reach into the realm of demons and produce a suitable familiar. The arcane chalk glows a white-blue as it pulses with mana being pulled from the surrounding ether. With each pulse, the manna is pulled into the hundreds of runes detailed throughout the circle, each dictating the terms of the would-be contract with Anna's hopeful familiar.
Feeling her glasses slide down, loosened by sweat, Anna pushes them back up and tucks her vibrant red hair behind her ears. Standing, Anna straightens out the rest of her appearance.
"I'd hate to look shabby, even for a demon," Anna says out loud, but only she is there to hear it. Anna straightens her tunic, pulling it down from under her small but shapely bust and brushing chalk off her leather trousers. Grabbing the cookies she had baked for her new demon familiar, again hoping demons liked sweats. She shook her head to herself, thinking, of course, demons like sweets. Everyone likes sweets. Anna stands in front of her circle, and with one last deep breath, she begins to chant the incantation. With each arcane word, the rune glow shifts from a blue-white to a more sinister black and red. Power coalesces in the center, and a void opens up in the middle, glowing white but also somehow absent the light, the center of the void being so black it makes Anna feel sick to look at it. Anna delivers the final words of the ritual, causing the void to burst with light and blinding Anna. When she opens her eyes again, a figure stands in the middle of the arcane circle where the void once existed.
"Are those cookies!" The figure asks excitedly. Anna was not sure what she was expecting from a demon familiar, but she sure was not expecting it to be so beautiful and incredibly not so erotic. The demon's skin is pure chalky white except for its extremities, which appear as if dipped in ink. The pure black coloring extends from its small-fingered claws to just past its elbows and from its feet to mid-thigh. Anna lost in gazing at the demon's appearance, only just realizes that it is completely naked and the demon possesses absurdly large breasts tipped with black nipples. Her gaze drifts from its breasts down to its groin, seeing the most alarming thing yet. A massive pure black, equine-like cock hanging semi-flaccid down to its knees and nearly as thick as Anna's forearm. She turns away, blushing furiously, embarrassed and unsure how to deal with it. The demon says with an annoyed tone.
"Are you just going to ogle my cock or answer my question. Are those cookies?".
"Uhh, yes, I made them for you. I thought demons might like them too." Anna stutters out, her face still flaming with embarrassment. The demon smiles and claps her ink-black hands together, sending jiggles through its significant bust.
"I've honestly never had a cookie before. Demons that have returned from contracts talk about food all the time, but we don't eat in our realm." The demon responds
"Oh, of course, I made them for you," Anna says, reaching into the circle and offering the demon a cookie. She struggles to maintain her balance, reaching into the circle while avoiding looking at the demon's erotic parts. So, Anna decides to focus on its face, which is just as striking as the rest of her. Full lips, a feminine face, and its eyes make Anna shiver. The iris glows white, but the outside sclera of its eyes is the same inky black as its extremities. A pair of straight, sharp horns on their head fades from pure white to black as they leave its skull. The demon's hair falls straight around its face and rests past its lower back. The whiteness of its hair is more so than even its skin.
"Here you go". Anna says, now unable to tear her eyes away from the demon as it takes the cookies from her hand. Its small, sharp nails moved gently across the skin of her hand. The feeling of something so obviously deadly dragging across her skin sends shivers down Anna's spine. The demon takes a tentative bite of the cookie, chews a few times, and bursts into laughter. A soft feminine laugh escapes its lips as the demon quickly eats the rest of the cookie. The sweet, soft, chewy cookie fills the demon with a pleasure they have never known before. It lets out a soft moan as it chews, clearly feeling the joy of chocolate for the first time.
"Oh yes, this is delicious heaven. Let us make the contract. My only stipulation is that you continue to bake me sweets. I'll do whatever you bid me." Anna giggles, surprised at how much she likes someone who is finally enjoying her baked goods.
"Then I just need your name". Anna says, pleasure radiating through her tone. This is all going so well, minus the massive cock and Anna's creeping feelings of desire for this demon. She shakes her head, trying to physically dislodge the thought of the demon's enormous cock from her mind. She can worry about it later. The demon smiles back, swallowing the last bite of the cookie before responding.
"Illia".
"Illia, I bind you and your power to my service until I release you or upon my death. Illia, you will serve me body and soul as my demonic familiar". Anna says, sealing the contract in the magical circle. There are quite a few more details to the contract than she spoke aloud, but the demons can read the arcane runes, and the words are just for the ceremony. Anna reaches into the circle once more and pricks her finger with a small needle from her pocket, drawing a few drops of blood. She lets them fall onto the binding rune within the circle. The rune flashes, then disappears. Looking up, Anna sees a flash of light near Illia's throat, and a small golden choker appears. The magic fades from the circle, and the room darkens to just the candles and the glowing potions in Anna's lab. Illa smiles and holds out her hand palm up towards Anna.
"Cookie, please," Illa says. Anna giggles again before handing over another cookie. This time, Illa grabs Anna's hand and pulls her in close. Anna stumbles and extends her hands to catch herself before she falls. Her traitorous hands land on Illa's massive breasts, fingers digging into the supple flesh. Illa moans with the pleasure of Anna's unintentional touch and pops the second cookie into her mouth. Illa says, mouth full of cookies again.
"I saw you staring human, but I didn't think you would make a move so fast," Illa chuckles, swallowing the cookie. Anna flushes and pulls away, her fingers reluctant to leave the soft flesh of Illa's breasts.
