NEO BLACK operates as a members-only secret prostitution ring, hosting nightly orgies of abnormal desires. Azusa Misaki, once hailed as a rising star in the BDSM scene, is attacked by a psychotic stalker, altering her fate forever. Sold off by the vengeful man who captured her, Azusa is recognized for her exceptional talent as a sexual toy and subjected to intense specialized training. Hidden beneath the surface lies a clandestine world of extreme adult entertainment, where deep, degrading sexual servitude goes far beyond ordinary adult services. To survive, she must endure relentless gangbangs, 76 rounds of continuous blowjob, creampie swallowing, pissing, and piss drinking in an unending cycle of extreme acts. Through it all, Azusa rises to the top, embracing her role as a living toilet, shining brilliantly in her new identity and forging a path like no other.
