Angela looked down her straight, pale nose at her brother's stiff form. He wasn't asleep, but was unable to move, held in place by her power. She never in her wildest dreams imagined that her twentieth birthday would end like this.
The change was dramatic and exhilarating. Just days ago she'd been a shy young woman, barely able to allow a man to molest her firm, tender breasts, let alone actively seduce him. Now, seduction and sensuality coursed naturally through her bloodless veins. She radiated sexuality and lust. No man could resist her. No man ever would again.
Her sire had ordered her to use her power to live out her heart's most wicked desire, and at the same time he revealed it to her, her shameful secret, the desire she thought no one knew, a desire she'd never truly admitted to herself.
She wore a loose, white shift, as sheer as a thin, night fog. The night wind, blowing in the open window, ruffled it smoothly over her slim, supple, feminine form. Her unearthly white skin, the smooth, pale knobs of her slight breasts, the white shift, the white sheets beneath her and her lover to be, all seemed to glow in the moonlight.
Angela let her hands slide forward, up her brother's legs, delighting in the tickle of his masculine leg hairs running over her fingers. Her dainty hands crept up and up, up his broad inner thighs, up the sensitive area of his groin, to stop on either side of his sinfully inviting cock.
It grew for her. She looked at it, and him. He trembled beneath her, frozen, as she projected lust into his mind. Her sire had taught her that. He'd commanded her to come here to demonstrate her new found powers.
She was a monster, now, he'd told her. He'd made her into a monster with one long, agonizingly euphoric bite on her neck. It wasn't only a bite, she thought, smiling. She supposed the bite was what mattered, but in the same moment he'd filled her wondrously with his hard, stingingly cold prick. He filled her and spread her, the first man she'd ever had, as wave after wave of pleasure coursed through her even as her life seeped away, to be replaced with an almost dreamlike non-life.
Angela lowered her open mouth to her brother's now stiff cock, as he stared at her in rigid fear, and trembled. When his living cock touched her cold, dead lips, it burned them like fire. She pulled back to see a wonderfully wicked blood red lipstick stain, an imprint of a sister's lips on her loving brother's cock head, a sinful brand marking him as hers, and a sign of only the start of what was to come.
She was a monster now. Her sire had told her what she had become, what she would do, and what he demanded of her. She would service him at his pleasure. She would feed on the living. In time, she would learn to kill, and to enjoy the exquisite pleasure that killing and feeding brought. And, when she wished, she could take other lovers, at will, whomever she chose.
That was a vampire's one greatest power. A vampire could instill an overpowering lust, a lust so strong, that the victim, no matter what his fears and intellect and inhibitions, would willingly succumb. They might know they were going to die. They might know the act they were about to commit was a heinous evil. But they would willingly, ardently submit, and enjoy it none the less.
Angela slipped forward across her brother's reclined form. Her hands slipped up his strong, hairy chest. Her thighs brushed his, and then the sides of his hips, as she shuffled forward to straddle him and settle into position.
Her sire commanded this one seduction. He said she was a monster. She had to prove it.
She had to feel her brother's cock inside her cold, dead cunt, and draw his living, burning, sinfully incestuous seed into her.
Angela lowered herself onto her brother's stiff shaft. The Sire hadn't really needed to order her to do this. She'd longed for it, shamefully, and secretly, for so very long.
"That's it, Mark. Stay perfectly still while little sister makes you feel so good," she purred.
His cock burned her cunt as it impaled her. The heat of it was inhuman. She giggled at the thought. It was she that was inhuman, and in her deathly state, it was the warmth of a living man that so burned her tender, nearly virginal insides.
Her living, breathing brother's cock burned her tight, wicked cunt.
The thought sent a chill up her spine. Her body tingled with pleasure as she lowered herself further onto him, feeling inch after inch of his awesome cock filling her, dragging across and spreading her narrow cunt lips. She watched his eyes intently the whole time. He somehow found the strength and courage to speak.
"No, Angie, no. Don't do this."
"Yes, Mark. Little Angie wants her brother's cock. Don't you want your little sister to be happy?"
She smiled down at him.
She lowered herself all the way onto him as she spoke, taking all of him, and ending with a glorious, pleasured wail. He trembled, then, as his eyes rolled up into his head and he tried to stifle his own involuntary, victorious moan.
"I know you like it. I like it, too, Big Brother. I like it a lot," she said, as she rode him, up and down, moving her brother's shaft in and out of her forbidden, incestuous, tight little cunt.
He shuddered for her. She giggled and smiled, relishing the power she had over him. He couldn't move. He was frozen, beneath her, as if he were dead himself, his cock stiff, not with rigor mortis but with his own excitement at being with his own beautiful sister, stabbing into her cunt, pleasuring her as much or more than any girl he'd ever had. Up and down she moved, letting her cunt slip over it, sliding easily, coating it with her plentiful juices. Her sinfully eager cunt clenched and grabbed, massaging her brother's prick mercilessly.
"Ooh, Big Brother, you fuck so good. Do you fuck your wife this good, Mark? Are you fucking me like you fuck your wife?"
