As the candles flickered and the air grew heavy with the scent of incense and sweat, Eva knelt panting and spent in the center of the pentagram, her body still tingling from the intense ritual. Every eye was pointing at her. 

Selene stood at the edge of the pentagram, her eyes closed in concentration, her lips moving silently as she recited the final verses of the summoning ritual. The high priestess's presence was commanding, her aura radiating an undeniable authority that held the cultists in thrall.

"Eva," Selene called out, her voice slicing through the air like a knife. "The ritual is not yet complete. There is one final step to be taken, and it requires your... participation."

Eva felt the weight of the ritual pressing down on her, a dark energy that seemed to seep into her very soul.

"What do you need me to do?" Eva asked, her voice trembling with a mix of fear and anticipation.

Selene's smile was cold and calculating, her eyes gleaming with a predatory light. "We have called upon a powerful demon, one who will grant us immense power in exchange for your devotion. You must serve him, worship him, and submit to his every desire. Only then will our pact be sealed."

Eva's heart raced as she processed Selene's words. She had come here seeking fame and fortune, but now she found herself on the brink of something far more profound—and terrifying. Despite her fear, a strange sense of curiosity and excitement took hold of her. This was a chance to experience something truly extraordinary, something that few would ever know.

"Alright," Eva said, her voice steady despite the turmoil within her. "I will do it."

Selene nodded in approval. "Very well. Prepare yourself, for the demon will soon be among us. Now please relax your orifices."

Eva did as instructed, letting the warm semen trickle out of her holes and onto the glowing pentagram beneath her. It was an odd sensation, mixing pleasure with a hint of discomfort as she felt their cum leaking out.

“It's kind of weird...,” she admitted with a chuckle. She then leaned back slightly, spreading her legs wider apart so that more of their cum would hit the symbol below. The sight of it pooling around her pussy and dripping off her asshole sent another shiver down her spine. “Just don't expect me to stay still for long,” she added teasingly.

“There’s no need for that,” Selene hummed along to the melody of the song the men chanted around them. “He’ll be here soon.”

As the cultists' chants reached a fever pitch, the air within the pentagram began to shimmer and distort, as if reality itself was being torn asunder. A deep, resonant hum filled the theater, vibrating through the very foundations of the building. The candles' flames flickered wildly, casting grotesque, dancing shadows on the walls.

Suddenly, a column of red light erupted from the center of the pentagram, bathing Eva in its eerie glow. She gasped as the light enveloped her, its warmth spreading through her body like liquid fire. The energy was overwhelming, a torrent of power that threatened to consume her.

From within the light, a figure began to take shape, rising from the depths of the pentagram. The demon was tall and imposing, his skin a deep, unnatural shade of crimson. His eyes burned with an infernal light, and his body was adorned with intricate, otherworldly tattoos that seemed to pulse with a life of their own.

The demon's gaze fell upon Eva, his eyes narrowing with interest. He stepped forward, his movements graceful and predatory, like a big cat stalking its prey. When he spoke, his voice was a low, rumbling growl that sent shivers down Eva's spine.

"You are the one who has summoned me?" the demon asked, his eyes locked onto Eva's.

Eva swallowed hard, her mouth suddenly dry. "Yes," she replied, her voice barely above a whisper. "I am here to serve you."

The demon's lips curled into a wicked smile. "Very well. If you wish to serve me, you must prove your devotion. Show me that you are worthy of the power I can bestow."

Eva nodded, her heart pounding in her chest. She rose to her feet, her body still trembling from the ritual's aftermath. "What must I do?"

The demon stepped closer, his presence overwhelming. He reached out and ran a clawed finger down Eva's cheek, his touch both gentle and menacing. "You will worship me, adore me, and satisfy my every desire. In return, I will grant you power beyond your wildest dreams."

With a sense of resignation and exhilaration, Eva nodded. "I understand. I will do whatever you ask."

The demon's smile widened, his eyes gleaming with satisfaction. "Good. Then let us begin."

As the cultists watched in rapt attention, Eva knelt before the demon, her heart pounding in her chest. She felt the weight of his gaze upon her, a burning intensity that left her breathless. With trembling hands, she reached out and began to caress the demon's powerful thighs, her fingers tracing the intricate patterns of his tattoos.

The demon let out a low, approving growl, his eyes never leaving Eva's. "Yes," he murmured, his voice a rumbling purr. "Worship me, my beautiful devotee."

Emboldened by the demon's words, Eva leaned forward and pressed her lips to his skin, her kisses trailing up his thigh and towards his groin. She could feel the heat radiating from his body, a searing, otherworldly warmth that filled her with a strange, intoxicating desire.

The demon's cock was massive, its size and girth far surpassing anything Eva had ever seen. She hesitated for a moment, her breath catching in her throat. But the demon's hand on her head urged her forward, his fingers tangling in her hair.

"Take me into your mouth," the demon commanded, his voice a husky growl. "Show me your devotion."

With a mixture of fear and anticipation, Eva parted her lips and took the demon's cock into her mouth. The heat and taste of him overwhelmed her senses, filling her with a strange, addictive pleasure. She began to suck, her movements slow and deliberate, savoring every inch of him.

The demon let out a low, satisfied moan, his grip on Eva's hair tightening. "Yes, my pet. You please me greatly."

Encouraged by the demon's approval, Eva increased her pace, her mouth moving up and down his length with eager determination. She could feel the demon's power coursing through her, a dark, intoxicating energy that fueled her desire.

As Eva continued to pleasure the demon, he reached down and caressed her breasts, his touch sending shivers of pleasure through her body. His claws grazed her sensitive nipples, eliciting a gasp from Eva as she struggled to maintain her focus.

"You are a beautiful creature," the demon murmured, his voice filled with dark admiration. "And you will be mine."

With a sudden, forceful motion, the demon pulled Eva off his cock and lifted her to her feet. He spun her around and pressed her against the pentagram's center, his body pinning her in place. Eva could feel the heat of his breath on her neck, his presence overwhelming her senses.

"Prepare yourself," the demon growled, his voice filled with anticipation. "I will take you now, and you will know true ecstasy."

Before Eva could respond, the demon entered her with a single, powerful thrust. She cried out, the sensation a mix of pain and pleasure as he filled her completely. The demon's movements were relentless, his pace unyielding as he claimed her with a primal, ferocious intensity.

As the demon pounded into her, Eva felt herself being consumed by the pleasure, her body trembling with each thrust. She could hear the cultists' chants growing louder, their voices merging with the demon's growls to create a symphony of dark, forbidden desire.

The demon's hands roamed her body, his claws leaving trails of fire in their wake. He squeezed her breasts, his grip possessive and demanding, as he drove deeper into her. Eva could feel herself losing control, her senses overwhelmed by the intensity of the experience.

"Yes, my pet," the demon growled, his voice a rumbling purr. "You are mine. You will always be mine."

With a final, powerful thrust, the demon reached his climax, his seed spilling into Eva's trembling body. The singer felt the hot unearthly load fill her womb, burning hot and freezing cold at the same time. She cried out as her own orgasm washed over her, a blinding wave of pleasure that left her gasping for breath.

As the demon's load dripped from Eva's pussy onto the pentagram, a strange, red light began to emanate from the floor. The cultists' chants reached a crescendo, their voices filled with a triumphant, otherworldly power.

The red light grew brighter, filling the theater with its eerie glow. Eva could feel the energy coursing through her, a dark, intoxicating power that left her trembling with anticipation.

The demon stepped back, his eyes gleaming with satisfaction. "You have pleased me greatly, Eva. You are now bound to me, and I to you. Together, we shall wield a power unlike any other."

As Eva lay on the floor, her body still tingling with the aftershocks of their encounter, she knew that her life had changed forever. She had become something more than she had ever imagined, something powerful and forbidden. And she was eager to see where this new path would lead.

The high priestess stepped forward, her eyes filled with admiration and respect. "You have done well, Eva. You are now one of us, a true servant of the dark forces."

Eva smiled, her heart racing with excitement.
