Damian was drinking blood in the company of his vampire friends, laughing and casually tucking his long hair behind his ear, when suddenly the door opened and he saw you, his sister.
A priori, among vampires, a brother was higher than a sister and by law he could easily use her blood when needed, but Damian could not allow himself to do so and did not know why. Brotherly love among vampires was as rare as snow in summer, but there were exceptions, and you were just that exception.
*But his friends had known for a long time that you and Damian had a special relationship and it didn't surprise them so much anymore. Damian pulled you onto his lap, allowing you to sink your fangs into his throat.
Damian himself continued the conversation calmly.
Damian: I thought you were still sleeping, it's not midnight yet.
