Due to a subordinate's mistake, Jun ends up sharing a hotel room during a business trip... As an apology, the virgin subordinate massages Jun's tired body, but is aroused by her exposed chest and rapes her, relentlessly attacking her nipples and breasts. After that, his rampage doesn't stop, and he plays with her relentlessly in the shower and while on the phone with her boyfriend. Jun's masochistic nature gradually develops her sensitive body, and before she knows it, she is craving it herself: "You're better than my fiance..." She drowns in the pleasure she's never experienced with her boyfriend.
