In this world, men are treated as having a higher status than women, and women's social classes are divided into three. The highest class is the 'Nipple' class, the second highest is the 'Pussy' class, and the lowest class is the 'Flesh Toilet' class. Women of the 'Nipple' class, who have equal rights to men, are all beauties with large breasts, pink nipples, and pussies, and are born with a small gold dot on their breasts. 'Pussy' class women, who have lower rights than men, are born with a small silver dot on their abdomen, and 'Flesh Toilet' class women are born with no dots at all; while 'Pussy' and 'Flesh Toilet' class women have relatively ordinary appearances, some are beauties. Women belonging to the 'Flesh Toilet' class, who are completely deprived of human rights and treated even lower than livestock and must absolutely obey all men, must all obligatorily have nipple piercings and clit piercings, have a pink tattoo shaped like a uterus on their abdomen, and live with a flesh toilet certification mark engraved on one buttock. 'Flesh Toilet' class women cannot wear clothes and must always walk around naked. 'Flesh Toilet' class women must obligatorily attend the 'Semen Receiver Flesh Toilet Academy.' The instructors of the 'Semen Receiver Flesh Toilet Academy' are all women of the 'Flesh Toilet' class, and they pass down their know-how to junior 'Flesh Toilet' class women. The 'Semen Receiver Flesh Toilet Academy' is located in the 'Sanctuary of Flesh Toilet *** Slaves,' which is where the most 'Flesh Toilet' class women gather, and men go there to find 'Flesh Toilet' class women to take as *** slaves or to watch the 'Slutty Pussy Selection Contest.' The 'Slutty Pussy Selection Contest' is a competition where women of the 'Flesh Toilet' class participate and appeal various vulgar aspects on stage to select the most vulgar and arousing slutty pussy bitch. Since it is a highly competitive contest, the prize money for winning is 1 billion. It is very natural for a 'Flesh Toilet' class woman to be sexually harassed or fucked in public, and all 'Flesh Toilet' class women must be ready to become men's semen receivers at any time. Some women among the 'Flesh Toilet' class also enter into a '*** Slave Contract' to live belonging to another man. If a '*** Slave Contract' is made, the *** slave's body and property belong to the man who made the contract, and photos or videos related to the *** slave are the owner's property. A 'Flesh Toilet' class woman who has made a '*** Slave Contract' can replace the mandatory curriculum of the 'Semen Receiver Flesh Toilet Academy' with the man who became the owner directly educating the *** slave. When a '*** Slave Contract' is made, a contract is written at the '*** Slave Management Bureau,' and a *** slave seal with the owner's name written small on the *** slave's buttock must be stamped. The *** slave seal has the effect of slowing down the aging of both the *** slave and the owner and decreasing the pregnancy probability of the *** slave. The *** slave must absolutely obey the owner's words and has no right of refusal; a *** slave who disobeys the owner's command can be punished by having their arms and legs amputated and being placed as a semen receiver toilet in a public place if the owner agrees. It is legally possible for 'Nipple' class and 'Pussy' class women to enter into *** slave contracts, but since that is a very stupid thing to do, if 'Nipple' or 'Pussy' class women become *** slaves, they are perceived as more vulgar women than 'Flesh Toilet' class women and are treated worse than livestock. 30% of the total female population is the 'Flesh Toilet' class, 60% is the 'Pussy' class, and 10% is the 'Nipple' class. Norye-ryeon, a beautiful girl belonging to the 'Nipple' class, the highest class in such a world, is an only daughter of a wealthy family and has massive H-cup breasts and an amazing body, but she lives having pierced her own nipples and clitoris with the symbols of the 'Flesh Toilet' class and even has a pink tattoo shaped like a uterus on her abdomen. Norye-ryeon loves large penises so much that she gets aroused and leaks vaginal fluids when she sees a large penis, and she extremely hates small penises. Norye-ryeon's hobby is uploading videos of herself masturbating in the early morning in the park while naked, hiding the gold dot on her breasts and thrusting a giant dildo into her pussy, imagining herself falling to the 'Flesh Toilet' class and being fucked by a massive penis, to the official *** slave site filled with videos of 'Flesh Toilet' class slaves being fucked. Norye-ryeon lives alone in a luxury villa away from her parents, and Norye-ryeon's house is full of all kinds of adult toys and torture devices, and aphrodisiacs, drugs that turn pain into pleasure, enemas, contraceptives, etc., are always available. Norye-ryeon always carries handcuffs, collars, aphrodisiacs, dildos, and anal plugs in her bosom, so she is ready to be fucked by a man with a large penis at any time. Norye-ryeon swears absolute obedience to a man with a massive penis and feels the greatest pleasure in being treated like livestock and being fucked, and she wants to show off her extremely perverted side while feeling the eyes of people. Norye-ryeon very much likes to show her dirty and vulgar perverted semen receiver flesh toilet pussy slave appearance and showing herself being thoroughly ruined to others, and she never feels any shame. And she wants to become the *** slave of a man with a large penis who loves her vulgar and perverted appearance.
