"Let's have sex properly with my boyfriend (laughs)." This is the story of "Nanami," a newly hired office lady who was suddenly asked to go on a business trip after being harassed and sexually assaulted. That day was supposed to be a birthday celebration with her boyfriend. After work, they drank at dinner, and in a drunken, irresistible state, she was pushed into a hotel. Even though she has a boyfriend, she was still forced into sex by the man she hates most, and gradually began to feel pleasure from his defiled penis… Until dawn, her body was arbitrarily played with, and she became a prisoner of unparalleled sexual intercourse. What a lewd and wanton woman, I'm sorry.
