Mira stood in her bedroom completely naked underneath the white silk robe draped around her nubile body. Moonlight shone through the slits in her window blinds, casting parallel lines across the carpet. The illumination was just enough for her to see her reflection in the bedroom's floor-length mirror. Her figure floated within the rectangle of black glass like a ghost, but Mira was too preoccupied to notice the eerie appearance of her reflection.
She was trembling with anticipation. Tightening the robe around herself, she shivered at the anxious longing between her smooth, dusky thighs. She bit down on her lower lip to keep herself focused and made herself critically examine her reflection. Her dark pretty face with its prominent nose and large brown eyes was thoughtful. She adjusted her long raven-black hair and lifted the slender chin she had inherited from her father. She pushed out the full bosom she had inherited from her mother, wondering if she should let the front of her robe open just a touch more.
Mirati Vazquez had an unlikely heritage consisting of ancestors from both Spain and India; although she had been born in America. She never even visited another country, but she would like to see more of the world someday. Preferably on a lengthy romantic vacation with a certain individual who would ensure there was as much sex as there was sightseeing on the trip. That individual was the reason Mira was nervously standing in her bedroom wearing nothing save a thin and naughtily short robe while trying to decide if her hair looked better draped over her right or left shoulder.
Finally deciding her hair looked more alluring over her right, Mira stepped closer to the mirror. Her bare feet brushed quietly over the carpet. Standing only inches away from the mirror, she bent until the tip of her nose was almost touching the glass. She took a deep breath, the motion along with her bending position making the front of her robe slip open even wider and revealing the inner curves of her breasts. Mira paid no attention. She closed her eyes for a moment, trying to steady the rapid, excited pounding of her heart. She re-opened her eyes and stared straight at the mirror. In a breathless voice, she whispered.
"Mistwalker. Mistwalker. Mistwalker."
Mira remembered the first time she had read about the Mistwalker. She had been browsing websites filled with creepy stories and urban legends. She had thought the Mistwalker was just another silly ghost story, and a rather derivative one at that. One was supposed to stand in a dark room, stare into a mirror and call the Mistwalker three times. People who did this claimed a black mist filled their vision, something Mira had thought was a perfectly normal optical illusion caused by straining one's eyes in the dark. The stories also claimed that sometimes after the third repetition, an evil being made of the swirling mist would appear to steal away one's soul.
She had never expected the stories would turn out to be true. Or mostly true.
Mira straightened up and stepped back from the mirror. She felt a chill grow in the room, but she made no motion to close her half-open robe. She waited, and she knew it was not an optical illusion when thin tendrils of inky mist began to flow out from the edges of the mirror's frame. The semi-transparent lines of darkness began to writhe in the air, flailing wildly like branches caught in a high wind. There was no sound save a faint sigh as the tendrils of mist abruptly plunged downward like a waterfall of smoke in front of the mirror. They wove themselves together in crazed, intricate patterns too rapid for the eye to follow. A pale glow began to shine within them as they formed into the huge shape of the Mistwalker.
He was inhuman, he was unclothed, and he was gorgeous. His heavily muscled form shimmered with a silvery light, much like the moonlight shining in the room. His head rose higher than the top of her bedroom's doors, almost brushing the ceiling, and it was crowned by a wild mop of pure white hair. The features of his demonic face were ruggedly chiseled, and his ears came to long points. His huge hands ended in cruel-looking claws.
The Mistwalker was not entirely naked. The dark mists flowed around his body and followed the movements of his silver, glowing limbs. He turned his face toward Mira, and his lips parted to reveal twin rows of sharp, white fangs. He let out a low, rumbling growl, and his pupilless eyes burned with a yellow light which would have made most people recoil in terror.
Mira did not recoil. She quickly stepped toward the towering apparition and flung her arms around his taut waist. She buried her face against the hard muscles of his torso. He was so tall her head barely reached his expansive chest.
"Oh Brook, I haven't been able to stop thinking you!" she exclaimed. She held onto him tightly while the spectral mists flowed over her arms, tickling her skin. She no longer felt unsettled by their touch, just as she no longer thought 'Brook' was a very odd forename for a supernatural being who had become a minor meme on ghost story websites. She had grown to regard the caresses of the dark mists sensual, and she found the name Brook to be absolutely adorable.
"It's felt like an eternity waiting to see you again," the Mistwalker who called himself Brook replied. His voice was deep with a hollow-sounding echo. His thick arms wrapped around Mira's body.
Brook leaned downward, and Mira raised her face. She rose up as high as she could on her toes to meet the fanged kiss he pressed eagerly against her lips. A much too long tongue pushed its way into her mouth, but she opened wide to accept its hot and probing length. Her own tongue followed it back and slipped past the rows of fangs, eagerly stretching into Brook's mouth. Mira sighed at his strange inhuman taste; a taste which she had grown to relish.
His powerful arms hugged her close, and Mira pushed herself against him. Her generous breasts were squeezed against his hard body. Each of her increasingly passionate breaths caused her globes to rub against Brook's bare skin through the thin robe, making her already aroused nipples stiffen even more. She felt one of his hands hold the small of her back while the other slid down her spine and cupped her rear. His fingers tightened around her buttocks, grasping her cheeks under her robe. Mira could sense the hungry desire in his touch, and she could feel the even more obvious desire in the thickening length of his cock hidden in the swirling mists between his thighs.
Unexpectedly, Brook broke their kiss. His tongue withdrew with difficulty from Mira's mouth. Mira tried to prevent its withdrawal with a murmur of disappointment, but Brook pushed himself back. Mira was left breathless and stared at him in confusion.
"You're so beautiful," Brook murmured in his haunting voice. One of his clawed fingers stroked the side of Mira's face. "But we need to talk."
"Later" moaned Mira, finally catching enough air in her lungs to speak. She reached up to grasp his neck and tried to pull him back down.
"We keep putting it off," protested Brook. "There are things you should knnn-!"
His words were cut off in a surprised clenching of his jaw as Mira gave up trying to tug his head down. Instead, she dropped her hands and slid them both into the swirling veil of mist between his legs. Her fingertips found the bulbous head of his warm member, and she slid her hand along its length. She shivered at the feel of the smoothly veined rod of flesh. She felt his penis instantly respond to her touch. His cock was already engorged with arousal and when she wrapped her hands gently around the girth, it swiftly swelled up stiff and hard.
"Oh Brook!" Mira moaned leaning against his chest. She turned her head up back up toward him. "I want you so-mmmmhh!!"
It was her turn to have her words cut off as Brook's arms enveloped her body and he fiercely renewed their kiss. He crushed her against him, pushing his hips eagerly against her stroking hand even while lifting her up from the floor as if she were weightless. He carried her toward the bed. He had become familiar enough with her bedroom that he could find the way to her mattress without stopping their passionate kiss.
When he reached the bed, he flung them both down onto it, making it creak loudly under their weight. His claws tugged and pulled her robe off. Mira squirmed and helped Brook fling the garment away while she still fervently kissed him. In a moment, she lay naked on the bedsheets, her exposed dusky flesh tingling with excitement at the touch of his silvery skin and the feathery caresses of the supernatural mist surrounding his limbs.
One of his hands moved down to her thighs, and Mira willingly opened her legs at his touch. She arched her back at the heightened pleasure as Brook's claws carefully and gently tickled around the mound of her flushed pubis while his long tongue explored her mouth and wrapped around her own wriggling tongue.
"Mmmmm!" Mira moaned.
One of her hands dropped to guide Brook's hand in its exploration between her legs while the other was wrapped behind his muscular neck, trying to pull herself deeper into the intoxicating, inhuman kiss. Mira could remember how her tongue had been hesitant when she had first touched the fangs filling his mouth, just as she had been fearful of his claws when they had stroked her. But even when she had been afraid of Brook's unnatural features, they had also been fascinating and alluring to her. Now she felt nothing but desire for them along with his more ordinary, human traits like the erection rising up between his legs.
Not that there was anything ordinary about the length and width of his pulsing shaft. Mira hungrily pushed Brook's massaging hand away from her already sopping vagina and shifted herself so her legs could wrap around his narrow hips. She drew him towards herself, feeling him shift until the hard knob of his cock was pressing against her labia.
