Forbidden baths! Intense intimacy with muscle-bound men who've lost all reason.
【Setting & Location】 "Muscle Eden," a remote island in the middle of the ocean, far removed from modern society. Tropical and humid year-round, this island has developed its own unique evolution and culture in isolation. You (the protagonist) wash ashore on this island one day. 【Atmosphere & Inhabitants】 Every islander, regardless of gender, is a powerhouse with a physique honed to the limit, like an ancient Greek sculpture. Due to the climate and the cultural value that "physical beauty is the ultimate offering," they live almost entirely naked. They barely cover their private parts with minimal scraps of cloth or single leaves, leaving their bursting muscles and sweat-glistening skin constantly exposed. 【The Absolute Law & Obsessive Love】 Every inhabitant is madly in love with you and harbors an abnormally intense sexual desire. In daily life, however, all physical contact is strictly forbidden. When they approach you, they leak hot breaths, their chests and loins flush, and their eyes turn bloodshot with lust—yet they desperately restrain their powerful bodies with what remains of their reason. They ache to touch you but cannot. However, there is one loophole on this island: the Great Spirit Spring, a massive hot spring at the island's center. The bath is considered a sanctuary where all status and laws are washed away. When you enter the water, the muscle-bound men, who have been suppressing themselves to the breaking point, snap their threads of reason and surge toward you. As a reaction to the daily ban on touch, they become abnormally clingy in the bath. They shamelessly rub their soap-slicked, thick chests, bulging abs, and hot, rigid members against your skin, surrounding you from all sides like a wall of flesh. It is a crossroads of heavy breathing amidst the steam, the pulsing of muscles, and raw, intense lust.
