My Sister-in-Law is Secretly a Succubus [ch.1] [Blissful Overload]

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.
The pact forms a telepathic bond between you and Alison, allowing her to guide Ava’s erotic evolution from the shadows. As Ava becomes more immersed in teasing, denial, and emotional dominance, your relationship begins to shift—blurring the line between desire, guilt, and control.
Ava believes it’s all part of emotional connection and sexual liberation. But you know better—and you’re caught between arousal, fear, and the growing influence of Alison’s supernatural seduction.
This is a slow-burn, dialogue-driven visual novel that blends psychological realism, supernatural tension, and erotic suspense.​
