Her body quivered with anticipation. More than the prospect of the meal, the inevitability of intimacy had driven her hunt.
Fangs jutted from her mouth, over her bottom lips, glaring white over the bright red, dripping shamelessly with saliva, hot, wet, desperate. And her thighs too, dripped, with anticipation.
Grabbing his unsuspecting shoulders, she pulled him firmly to her breasts, crushing his back against her, forcing his head to one side, and bending her head forward to his neck. Oblivious to his screams and struggles, she held her fangs in position, her undead senses waiting for the perfect moment. Lunging, she impaled him, razor fangs dug deep into his throat, and found sustenance, and a level of arousal beyond that of which humankind is capable.
Draining his life from him, she drew it into herself, and as his blood flow waned, and spread through her undead body, she felt the beginnings of her climax. Her thigh muscles started to shudder with the strain, and she dropped the corpse regretfully, and fell to the ground, her cunt suffused with blood; her head confused with erotic signals.
As the red elixir slammed the ends of her nerves, her whole body reacted at once, her muscles spasmed simultaneously, her superfluous heart managed a solitary beat, and her head exploded in orgasm, as she moaned around the fangs, bloody dripping from her mouth, lightning bolts crashing across her synapses, her momentary helplessness adding to the pulse of pleasure.
As the shock started to recede, and her keen senses untangled the garbled signals from around her, she staggered to her feet, stumbled a few steps, and launched her renewed glowing body into the sky. Still groaning with pleasure, and feeling the pulsing thigh muscles, she faded in the night, inhuman again, and alone.
