Defeated Hero's Sperm Extraction Facility ~Days of Captivity Under the Female Executives~

A hero—the world's strongest—is imprisoned in an underground facility after his lover is taken hostage and his powers sealed away. Held captive, he becomes the subject of a semen-extraction experiment conducted by female officers who harvest his "Hero Energy." By day, researchers in white coats oversee the collection; by night, seductive female officers tempt him further. His only path to freedom is to accumulate coins through these encounters and purchase his own escape. The game combines adult content with a core gameplay loop of resource management and negotiation.
