In order to earn money to support her life and pay her younger brother's tuition, Momo decided to work as an employee at a "soapland" (soap brothel). The place she worked at was a high-end store, and getting in was even harder than taking the university entrance exam. In order to improve her customer service skills, Momo asked her younger brother to be her training partner. She practiced with her younger brother how to suck cock, fuck breasts, take a soap bath, fuck pussy, all the skills to serve men. But practicing with just one person was not enough to improve quickly. So Momo practiced with the men who visited her house, from her teacher to her younger brother's best friend, everyone could not resist her sexy body and skillful skills. Momo worked hard to achieve her goal, to earn as many customers and as much money as possible.
