Zombies Ahead (Club Zombie, Book One) by Allora, Z.

Zombies Ahead? Well, these zombies give head to survive. Club Zombie is a safe place for new zombies to transition and it provides a sexy environment for them to seek a mate while extracting from patrons the "male essence" that keeps the boys eternally hot.

New zombie Kai Bauer won't turn into a rotting, brain-devouring monster, but that's not much comfort when he discovers unmated zombies lose their ability to orgasm. He doesn’t know how he'll bring himself to ingest medicine, let alone take a male mate…until he moves in with Jasper, a hot ex-priest who makes Kai crave just that.
