Tsuma no Mamorigami

You watch your own wife from your own body, in your own home, as she changes into someone else. That's the whole pitch: a first-person netorare piece built to make the room feel real enough that you're stuck standing in it.

There's no real story beyond that setup, just the husband's point of view and the slow, deliberate reveal of what he was never supposed to see. The 3D presence does the work a script normally would, putting you in the doorway rather than in a dialogue tree.

Play consists of watching, following, and reacting from behind the protagonist's eyes as scenes escalate through teasing, pressure, and betrayal. It's less a game you steer than a scene you're trapped inside, framed to keep you looking even when you'd rather not.
