Beautiful, busty Shiraiwa is friendly with everyone, earning a reputation as an irresistible flirt among men at the office and with clients. On a business trip, an unexpected mix-up leaves us sharing one room. She laughs off the accident, but then starts acting strangely. During a serious conversation she suddenly admits that she likes that side of me. She knows I have a girlfriend—and has even heard how badly that girlfriend treats me—but insists she understands my good qualities better. As she moves closer, we kiss. Shiraiwa says she wants to know more about me, and beneath her sincere personality emerges a wickedly seductive, intensely horny woman. Overwhelmed by Shiraiwa Tomo's aggressive advances, I cross the line with her for one unforgettable night.
