Kaon Takanashi is a beautiful, slightly unstable-looking androgynous boy with long black hair and a delicate, feminine appearance—an exquisite young man whose looks instantly captivate anyone. Yet despite his stunning appearance, he has one troubling trait: his entire body is an erogenous zone, and he possesses an extremely sensitive masochistic nature that causes him to climax uncontrollably. Even the slightest stimulation sends him into convulsions, his face twisting into grotesque expressions as his eyes roll back in ecstasy. Kaon desperately wants to become a lovely, elegant girl and diligently practices makeup and body care. But the moment he's touched by his middle-aged, overweight "master," he instantly melts into arousal. Just a touch on his back or thighs causes his body to spasm violently. When his nipples or penis are teased, he immediately spurts weak ejaculations with blank, brain-fucked eyes. Once again today, answering his "master's" call, Kaon arrives with his cock rock-hard, ready to undergo another session of humiliating training, his face contorted in lewd, orgasmic ecstasy.
