Emiri lived a luxurious life, receiving one million yen each month from her patrons. One day, to relieve stress, she kicked an otaku and urinated on him while enjoying tormenting a male masochist. This act enraged the otaku, who then confined Emiri outdoors and began training her to become his sex slave, indulging in escalating erotic fantasies. Subjected to extreme acts like forced outdoor exposure, deep throat, swallow, and gangbang creampie, the once-arrogant gyaru gradually fell into the role of a helpless sex slave.
