The underground diary of 'Aoi,' who has been trained for three months in the NEOBLACK underworld organization. 'Please use me as a meat toy however you like.' Brainwashed Aoi is played with by sadistic men, making them feel good while she is gradually turned into a slave. Being licked all over, intense deepthroating, and swallowing semen are all routine. Even when tormented with various toys, the erotically brainwashed Aoi isn't satisfied, and in the end, she is relentlessly fucked by sadistic men.
