About this game

Ava’s laughter fills the room, her teasing touch both a comfort and a challenge, keeping you on edge as her emotional dominance weaves through every moment. Beneath this surface of marital bliss lies a secret darker than you imagined - a half-sister named Alison, a succubus whose seductive hunger threatens to consume everything you hold dear.

One fateful night, you catch Alison in the act of feeding, a revelation that could shatter your world. Instead of turning her in, you make a perilous bargain: you will keep her secret if she helps you transform Ava into a "hotwife," embracing a new facet of erotic freedom.

Alison, intrigued by your submissive tendencies and the mysterious potency of your essence, agrees to the pact. This bond allows Alison to subtly influence Ava’s transformation from behind the scenes, steering her toward deeper layers of teasing, denial, and emotional dominance.

Ava believes these changes stem from emotional intimacy and sexual liberation, unaware of the supernatural forces at play. Meanwhile, you wrestle with conflicting feelings - arousal mingled with fear, desire entangled with guilt, and control slipping through your grasp as Alison’s influence grows.

This visual novel unfolds as a slow-burning, dialogue-rich exploration of psychological realism fused with supernatural suspense and erotic tension. Every choice echoes with weight, every interaction layered with complexity as you delve into themes of female domination, corruption, and the mystique of interspecies relationships.

Play now to uncover the secrets lurking beneath the surface of your marriage and test the limits of desire, trust, and control.
