Lunarnalia

Every summer the mountain town of Crater Hallow throws Lunarnalia, a solstice festival honoring the moon goddess Luna, and every year the local church makes sure it's more than just fireworks and prayer. Gabriel gets pulled into the town's religious weirdness, digging into secrets tied to the church of Lunarology, his neighbors, and even his own family, all while something out there seems intent on wrecking his sanity and his virginity in equal measure.

The story follows Gabriel as he tries to figure out what Lunarology actually worships and why everyone around him, friends included, keeps acting like they know something he doesn't. It's a small-town horror setup dressed in festival lights, with the church at the center of whatever's really going on.

As a kinetic novel, there's no branching to fuss over: you read, you watch the town's rituals close in on Gabriel, and the femdom-leaning encounters play out as part of that descent rather than as choices you make. The weight-gain angle mentioned by the creators is baked into the same slow, creeping tone as the rest of the horror.
