A trend in the changing AV industry is the increase in female assistant directors. What does their job entail, and what is rewarding about it? To find out the truth, we follow the hard day of Uta Hibiki, an AD in her first year at the company! Hibiki-san joined the company despite being offered a job as a news announcer at a major broadcasting station in order to fulfill her dream of "shooting realistic sex scenes." Before filming, she checks the smell and erection of the male actors, takes care of famous cast members who should not be offended, and even models for sex scenes filmed by the director and veteran male actors to understand the feelings of the actresses? She says her nipples are very sensitive. After showing off her amazing face at work, she gets a big dick thrust into her and another one deep in her throat. It must be a tough job to have to cum so much while at work!
