Ruka Inui, a debt-ridden, big-breasted wife sold to a bubble bath parlor specializing in anal licking CEMD-898

Ruka, an innocent and naive young woman, is a pitiful wife sold by her good-for-nothing husband. After being taken to a bubble bath shop by underground financiers, she is stripped naked and subjected to a full-body examination. She is favored because of her large, voluptuous breasts and white vulva, and thus signs a contract at a bubble bath shop specializing in "anal licking"... Day after day, Ruka licks customers' anuses, gradually finding a sense of accomplishment in her work among numerous requests and regular customers. Sometimes she uses unprotected sex to capture customers' hearts and penises, and unknowingly, Ruka grows to the point of being known as the "Queen of Anal Licking"... After the shop manager personally instructs her on prostate development and the techniques of using a penile ring (Peniban), Ruka uses lewd language to tease and harass the perverted manager, bringing his anus and penis to frenzied orgasms, leaving him completely limp! After becoming a high-class bubble bath hostess, embodying all the expectations of the establishment, Ruka kneels with three fingers to greet customers. When she looks up, she's confronted by the man from the underground finance industry. Her life has hit rock bottom… Having climbed to the top from her previously despised bubble bath job, Ruka has unknowingly paid off all of her good-for-nothing husband's debts on her own. The finance man feels sorry for Ruka, who has always only been able to serve customers at the bubble bath, so on this day, he uses his large penis to bring Ruka to a frenzied orgasm, reversing roles and serving her for the first time!
