You’re married to Ava—a bubbly, nurturing, and emotionally dominant woman whose teasing affection and playful control keep you constantly on edge. She’s everything you’ve ever wanted… and everything you secretly fear.
What she doesn’t know is that her half-sister, Alison, is a fully awakened succubus who seduces men and sucks out their soul during sex. One night, you witness Alison feeding—and instead of exposing her, you strike a dangerous bargain. You’ll keep her secret… if she helps turn Ava into a “hotwife.” Alison, intrigued by your submissive desires and the unique power she senses in your sperm, agrees.
