Anyone who sees Nanako can only think of her as a pretty, beautiful girl. - (I really want to be raped by a man in the form of a girl...) When Nanako is caught up in these thoughts, her husband appears in front of her, a middle-aged man who is older than her father and has metabolic syndrome. - The perverted act between the pretty Nanako and her metabolic husband is a training process in which the beautiful young Nanako is run over by a middle-aged man and reduced to a pet animal. - Outdoors, in the garage, in the bathroom, in a hotel room... A beautiful girl and a middle-aged man sip each other's saliva without worrying about other people's eyes. - Nanako's semen is slurped up by the master, mixed with saliva in his mouth, and returned to Nanako's own oral cavity. - She is made to ejaculate in the mouth by middle-aged cocks many times during fellatio, and is made to swallow all of the middle-aged semen. - She becomes horny while licking and servicing a middle-aged anus with her lovely tongue, and then she cries out as a masochist while having anal sex while being laid under her metabolic belly. - This work is a clear record of Nanako's training to become a masochistic pet, as she climaxes in convulsions due to the "pleasure pickle" of shame and masochism.
