The servant didn’t scream though, they had been indoctrinated into the coven as a blood slave, as all humans were. They’d do duties and what not, but they were spelled to let the vampires feed on them whenever.
Eric watched as she fed upon the human, and he stood, heading over to her, catching Cassandra as she backed up, the servant thudding to the ground. He turned her around and had her look into his eyes. His eyes were mesmerizing and he muttered something she wouldn’t understand but that blood lust urge dampened slightly, yet her next victim wouldn’t be a victim per say.
He then had a line of human servants for her, and he watched her intently. “Here, watch me,” he spoke, going up to a human and feasting upon his neck, closing his eyes as he drank, but did not drain completely- pulling away after a few moments. He then wiped his mouth and walked back over to her, touching her sides sensually and leaning next to her ear, “See? How about you try next?” He was trying to make the feeding process..easier for her.
