To combat the drop in work efficiency caused by rising libido during work hours, the company implemented the role of a "Sexual Fulfillment Employee" - someone who handles the employees' sexual needs at any time. In addition to their regular duties, these employees must quickly and discreetly satisfy employees' desires, both at the office and in their homes, using any method the employee prefers. However, Sakura-san, a new Sexual Fulfillment Employee hired this year, has received numerous reports from colleagues stating that she didn't comply with their preferred methods or refused to process their semen. This has led to an urgent need for her to undergo retraining as a Sexual Fulfillment Employee. Through practical exercises, she will review the fundamentals of oral sex, including proper tongue techniques, ensuring that all semen ejaculated into her mouth is consumed, and the importance of internal ejaculation within the vagina. Ultimately, she will be trained to utilize her entire body to simultaneously satisfy multiple employees' sexual needs.
