Yuki, an honest and cheerful female college student, has a slightly shy personality. During her first visit to a brothel for a job interview, she is surprised by an unexpected practical demonstration. The establishment's unique feature is that creampie services without condoms are permitted. Through the interview process, she undergoes sexual training, and her tension gradually builds as she interacts with clients. Eventually, she is forced into creampie sex by an aggressive customer, her expression growing increasingly distressed.
