Latex Island [v1.1.6 Demo] [Sepia Oulomenohn]

January 9, 2026F95

Latex Island
Lathe is an apprentice imperial summoner, and not a very good one at that. But when a botched ritual sends her to a mysterious island, host to both the ruins of a lost civilization and an amnesiac imperial colony, she finds herself wrapped up in conspiracy, conquest, and the all-encompassing embrace of latex.
Features a novel sensory system, involving sight, sound, scent, and the restriction thereof, as well as the promise of erotic puzzles and scenes focused around a nervous but eager main character.
