Whack.
The silver-laced crop raised a bright red welt across the back of the broad-shouldered, male vampire. Bound and gagged, he hung from a triangular metal frame that had been constructed for this explicit purpose.
Crack.
The crop struck again, hard enough that this time the vampire's back arced from the pain and he cried out, the sound muffled by the ball gag strapped into his mouth and wedged firmly between his teeth, just behind his extended fangs.
"Do you know what you did wrong?"
Whap.
The crop struck a third time, and he arched so violently he flung his head back, long, silver-white hair fanning briefly in the air over his head. He gasped for breath as the sharp, violent sting of the silver chain wound round the crop left a long-lasting burning sensation where it had raised a long stripe down his spine.
"Do you?"
The crop struck yet again, this time aimed at a previously left mark. The vampire cried out into his gag again, jerking against the confines of the metal frame. His cuffs were laced with silver, the body harness that wrapped around his torso was laced with silver - even his ball gag contained traces of it. The only thing in the room not touched by the metal known for its weakening qualities against vampires was his blindfold: that, and only that, was mercifully free of the silver. It was a cool, refreshing softness against his eyes, anchoring him as wave after wave of heat and arousal coursed through his body.
He whimpered, flinching as the tall figure behind him raised the crop yet again. They were clad in dark leather, even their face was obscured by a mask enchanted with a spell that modified their voice, while the rest of their worn gear was enchanted to hide from him their true smell, even their taste. They could have passed him in the hallway of his workplace earlier that same day and he wouldn't have been able to recognize them.
The crop returned to his skin, but this time, it was gentle and caressing. He didn't dare yet relax, but he leaned into it to communicate that he was not past his limit. The tip of the crop hesitated, acknowledging his current state, and then it slid down his back. He shivered as the tip of the crop slid between his buttocks, gently stroking the most sensitive, vulnerable area. He ached with need to be claimed and penetrated, shaking slightly from the force of his desire. He moaned into his gag, arching his body into the touch of the crop between his legs, uncaring of the faint, burning tingle caused by the silver.
"Do you know," the voice said next to his ear, the leather mask brushing against his neck, "what you've done wrong?"
The vampire tensed, and then nodded his head.
"Are you ready to beg for mercy?"
