A video posted showing the inside of a warehouse located in Chiba suburbs, featuring mostly middle-aged men working there as part of their dispatch jobs. However, among them stands out a young woman named Tsubasa (age 22), who serves as the office's beloved little sister due to her agreeable nature and willingness to help others with their sexual desires. Despite her plain appearance and innocent demeanor, she finds herself constantly harassed by her co-workers both on and off the clock. From being pressured into drinking canned beer after work to getting fucked at a cheap hotel, poor Tsubasa seems unable to escape her predicament.
