Ruka, a naive woman, is a pitiful young wife sold off by her useless, trashy husband. Brought to a soapland by a loan shark, she is stripped and examined thoroughly. Her plump, huge breasts and shaved pussy are highly praised, and to her shock, she ends up signing a contract for a soapland specializing in "anal licking"... Day after day, as she licks the anuses of her customers, Ruka begins to find fulfillment in the numerous requests and repeat clients. Sometimes, she captures the hearts and cocks of her customers with raw creampie sex, and before long, she grows to be known as the "Queen of Anal Licking"... Taught directly by the shop's president on prostate development and the use of penibans, Ruka entertains the perverted president with dirty talk, making his anal and cock cum repeatedly until he is completely drained! Having become a high-class soapland girl carrying the shop's expectations, Ruka greets a customer with a traditional three-finger bow. When she looks up, it is that same loan shark standing there. From the rock bottom of her life... Ruka, who climbed to the top of the soapland work she initially hated, had unknowingly paid off her trashy husband's entire debt on her own. Feeling sorry for Ruka, who had done nothing but serve customers until now, the loan shark uses his big cock to make Ruka cum repeatedly on this day, reversing their roles to serve her!!
