Yukari rather enjoys her extra work that she does at her family's bathhouse. She loves to be able to assist customers in a very special way, and because of this, she has become rather popular with a lot of guys in the area. After all, when rumors spread about a preteen girl willing to help younger boys jerk off, and old men have their way with a young pussy, it is no wonder that customers flock to her, eager for her services. Whether she is sitting on an old man's lap in the water, letting him bounce her on his cock while he moans, or working her hand up and down the length of a young boy's small, twitching member, explaining to him how to make it feel all better, she couldn't be happier. Like this, it is clear that she has a talent for customer service, and the more customers demand her, the more obvious it becomes that she is the biggest selling point of the bathhouse. Which means that she is stretched rather thin, unable to take care of all of this work on her own. Fortunately, she has some friends who are eager to volunteer their assistance, once they find out that she has been overworked. Though Doremi, Hazuki, and Aiko seem a little confused at first about the purpose of Yukari's job, it does not take long for them to catch onto all of the things that they need to learn. In fact, the three of them are naturals, and once they have been hired to assist her, the popularity of the bathhouse only goes up. They all have quite the knack for pleasuring customers, with Hazuki a great teacher for the boys, and Aiko and Doremi more than capable of wearing the old men out.
