Fantasy

[WARNING: This book contains explicit R18 scenes]
    After the Catastrophe, the rich and the gifted built walls and left the rest of us on the other side. The plain, where zombies roam and survival is the only way to live.
    When the zombies finally caught me and sank their teeth into my neck, I didn't die. I awakened the Lewd Leveling System.
    [Core Rule: Have sex with female ability users to recharge, level up, and grow stronger.]
    [Every moan, every orgasm, every scream gives EXP.]
    Sounds great, right? Except the real problem starts when I make it inside the walls. Because every time I sleep with a female ability user, she charges and levels up too.
    ***
    In a world where ability is power and every ability user is slowly burning out, a Charger who can boost anyone's gift is the most wanted man alive — and Abram Nadez is the only Charger.
    How is he supposed to keep a low profile when every woman — students, teachers, administrators, MILFs — wants a sample, and every man who's lost his wife, girlfriend or mother to him wants him dead?
