Matsumaru-san, the reliable older sister figure in the sales department, is especially popular among junior employees. However, she had been firmly rejecting filming offers. So, we approached her, a frugal woman, with a slightly suggestive side job within the company! We managed to capture her in a compromising position! The sex after a two-and-a-half-year hiatus for this 27-year-old office lady, who's dedicated to her work, was an incredible contrast!
