Mitsuri is horrified to be assigned the same room as the boss she despises on a business trip. He drugs her, secretly records her, and uses the footage to blackmail and assault her.

He taunts her that her boyfriend cannot satisfy her and forces her through repeated humiliating orgasms until she squirts uncontrollably.
