Succubi Magic

This is my very first post. Should I keep going with part 2 ???? I have some investing ideas.

Having moved into an old mansion, the brother and sister explored the old library. Susan and her 18 year old brother reached for the same book at the same time.
The book opened with two small puffs of wind. At first there was a feeling that they were going to be pulled into the ancient tome. They grabbed each other and with a monumental effort they managed to fall away. Surprisingly, they heard the book slam shut. The gold emblem was still pulsing and they felt drawn to it. "I want to touch it, said Susan" Robert responded with, "I want to touch you!" He reached out and grabbed Susan's arm, pulling her towards him. Susan looked into his eyes and felt something she hadn't felt before. The rain outside grew louder, seemingly in sync with the beating of their hearts.
Robert held her tightly. His arms around her back. She held him likewise.
Both gasped at the same time. "why did you do that?" gasped Susan. "You ran your hand right up my inner thigh!" Robert looked stunned himself. "My arms are around your back. I felt you touching my...my....dick. But it couldn't have been you." Susan's voice was shaking. "It wasn't me!" she exclaimed. The room grew warmer and the gold emblem on the book grew brighter.
Susan stretching as far she could touched the glowing emblem with 1 shaking finger.

The moment her skin made contact with the warm metal, a jolt of energy shot through her. She stifled a moan as the energy spread through her body, reaching parts she had never felt before. The gold light grew brighter, enveloping her hand and then her entire arm. The book vibrated and the pages began to turn rapidly, as if by an invisible force.
"What's happening to me?" Susan whispered, her eyes wide with fear and awe.
Robert, unable to resist the pull, reached out and touched the emblem with his own trembling hand. The same jolt hit him, but instead of fear, he felt a strange sensation of power, his body tingling with an unfamiliar heat. The gold light grew even more intense, and the two teenagers found themselves locked in an embrace, their bodies reacting to the ancient magic.

The stereo voice, a haunting mix of masculine and feminine tones, echoed through the room. "We will have fun with you," it purred, the sound seeming to come from everywhere and nowhere at once. "You will be innocents no more." The words sent shivers down their spines, but also a thrill of excitement that they couldn't explain. The air grew thick with anticipation, as if the very walls of the mansion were holding their breath, waiting to see what would happen next.

Susan and Robert couldn't tear their eyes away from each other's bodies. The rain outside had turned into a downpour, the sound of it drumming against the windows melding with their own rapid heartbeats. The gold emblem grew so bright it was almost blinding, and the heat it emitted was palpable, a warmth that seemed to seep into their very bones.

Robert's gaze dropped to Susan's chest, where her breasts strained against the thin fabric of her top. Her nipples were clearly visible, standing out like two tiny bullets, betraying her arousal. He had never noticed before how perfect they were, how they begged for his touch. His mouth went dry and his pulse quickened as he imagined the sensation of his thumbs brushing against the hardened peaks.

Susan felt his eyes on her and her cheeks flushed even more, her breath catching in her throat. She looked down and noticed the bulge in Robert's shorts. It was unmistakable, and it sent a thrill of desire through her that she had never felt before. Her eyes grew wide as she took in the size of it, the realization that her younger brother had grown into a man hitting her like a sledgehammer. Her thoughts swirled with confusion and excitement.

Her hand moved almost of its own accord, reaching out to touch the pulsing emblem again. This time, it was not just her fingers that felt the heat, but her entire hand, her wrist, and forearm. The gold light grew even brighter, and she watched in astonishment as her hand slid away from the book and reached towards Robert's shorts.

With a gasp, she felt her hand rub against the fabric that contained his burgeoning arousal. The warmth and hardness of his desire sent a jolt through her, and she felt her own body respond in kind. The room was spinning now, the rain outside a distant crescendo to the symphony of strange, new feelings that were taking over.

Robert could only moan in longing, feeling the intimate, forbidden heat of his sister's body so close to his. His hands, as if guided by a will not his own, reached up to cup Susan's breasts through the thin material of her top. The feel of them in his palms was heavenly, and he could not resist the urge to pinch and roll her nipples. Susan's breath hitched, and she leaned into his touch, her body arching slightly, offering herself to him without words.

Her eyes opened wider, "What happened to my bra?" she murmured, realizing it was no longer there. The gold emblem's power had removed it, leaving her breasts bare and exposed to his eager touch.

"I don't know," Robert panted, his eyes never leaving hers as his thumbs traced circles around her now-bare nipples, "but your shirt's gone too."

In an instant, they were ripped apart, the gold light dissipating like mist. The emblem grew quiet, but the room remained charged with an electric tension that seemed to crackle in the air. They stumbled backward, their bodies protesting the sudden loss of contact. An opaque glass had appeared between them, a sudden and impenetrable barrier that reflected their shocked expressions.

On the other side of the glass, two figures materialized, their forms undulating and shifting as if made of shadow and light. The figures coalesced into the forms of two succubi, their voluptuous curves and sharp features a stark contrast to the innocent teens before them. The creatures looked identical, save for the one with hair the color of a raven's wing, her eyes a piercing green, and the other with locks of fiery red and eyes that burned like molten gold.
