A factory worker with a hidden G-cup bust, forced to repay a work mistake with her body, becomes the young company president's sex slave... Unexpectedly awakens a secret M-like business order. (Yui Sayama, FOCS-252)

After graduating from high school, Yui worked diligently at a warehouse in her hometown. One day, she made a serious mistake at work and was forced to negotiate with the president of the company—the president's son. Previously, the president had sexually harassed Yui, causing her distress. However, instead of blaming her for her mistake, he demanded that she repay him with her body. Unable to resist, Yui finally yielded, and from that day on, the president came every day to demand her voluptuous figure, which concealed a G-cup bust.
