Deadly Girl's Lascivious Nature

When Irene, a pure senior high school student of the third grade, was about to turn 18. There were inexplicable wounds on her body, which violated the law of "not bleeding in public". Just as the noble young man of Blood Clan, Hosen, trapped Irene and couldn't help revealing his vampire fangs, the young man's uncle, the leader of Blood Clan, the handsome, calm and mysterious Howard, saved Irene. And he also sensed the smell of her blood. It was the extremely dangerous and crazy succubus blood. Decades ago, the extinction of the succubus had something to do with the fight for power of the Blood Clan. With a sense of guilt, Howard didn't refuse Irene's approach and helped her to complete the succubus's coming-of-age ceremony. After the first night, the wounds on the body of the little succubus were completely healed, and part of Howard's power was absorbed by her... Since then, Irene, who was ignorant of the world, had awakened her instinct as a succubus... In order to satisfy Irene, who was a succubus, Howard had made great efforts to explore innovations and improve himself... (The third grade of high school was the last grade of high school. The first night was in the early morning of the eighteen-year-old birthday, and she was an adult.)
